The engine itself can be much cheaper and more reliable if it is produced in bigger numbers and covers more units of the VKS

Yeah, like the engine for the F-35 will be cheap if they cancel the other engine so everyone has to use the same engine so you save money because one engine gets all the sales... except that didn't work.

A bit of competition gives your customers some choice... with an aircraft like the F-35 you can have different engines that might improve different aspects of flight performance... one customer might want the aircraft as a pure fighter in which case an engine that allows higher supercruise speed might be preferred, whereas another customer might prefer the engine that gives the greatest range in high subsonic low altitude penetration flights for more strike roles...

Sukhoi has already explained the reason for the single engine plane and why it is cheaper than twin engine (it should be obvious regardless), no need for me to insist on their arguments.

Yeah, and if they made a three engined plane they would explain that that was the best design solution too... at the end of the day it comes down to what the customers want... and what their alternatives might be.

It was done by UEC which means 1 trillion times more in the know than you or me...

They would know more than us, but certainly not a trillion times.... I would say the person in purchasing for the military customer would know better than the guy in marketing for the producer...

Maybe, but they were covering basically the whole range of applications in UEC's future portfolio.

And any producer would love for all their customers to want their best product and nothing else... it very much simplifies things... but having one tool to solve all your problems is a bit like the opposite of the old saying... when the only tool you have is a hammer treat every problem like it is a nail.

Those plans passed the drain long time ago. We have fresh statements from Slyusar (it should serve as food for thought that he stresses the fact that the LTS has the kind of performance it has re. payload and range in order to attend the VKs' needs) and we all know VKS will buy the Su-75. But ok.

It hasn't even flown yet, let alone passed any tests or been compared with any competing project... it would be criminal for him to state it was the plane they want and he should be removed from his position if he did so... otherwise it makes a mockery of procedure and rules.

They need money to actually bring those ideas to metal and that is where investors may not want to take the risk.

Promising something they know they can't deliver is no help to their situation... no risk or low risk usually means no or low reward.

Then you are missing what UEC is about. There are simply no resources to have several manufacturers of equivalent engines competing for the market, not if you need to keep up with the advances of your adversaries. This is no joke, they need to concentrate efforts to face the West now and China in the imminent future.

UEC is about retaining design skills, so having factions inside the company competing for different jobs makes sense... once jobs are allocated then you can cooperate to make things better, but giving all the jobs to one faction just makes one faction fat and lazy and overloaded with work... and defeats the whole purpose of keeping the different engineers and technicians.

Not to mention each faction has its own partners in electronics and engines and systems which also need some work too.

Giving all the plane jobs to Sukhoi and all the engine jobs to Saturn and you will find you will continue to depend on them because the other design bureaus will shrivel up and die without funding or activity.

The Checkmate looks like a good plane, but lets see what MiG or Yak can come up with first before we call it a done deal... some of the features of the izd 30 engine are very good and state of the art but Klimov and Salyut have not been sleeping either.

Concentrating their resources into one branch of one company and you end up like the US where Boeing made the F-35 and Northrop/Whoever used their XF-32 funding to really work on new stealth technologies they wanted to apply to other aircraft... they didn't really even try to win.

A. Inozemtsev - on the prospects for engines for aircraft from Tu-214 to MS-21-400, 08.18.2022.

Alexander Inozemtsev, Deputy General Director of JSC UEC for the management of NPK Perm Motors, Managing Director - General Designer of JSC UEC-Aviadvigatel, spoke on the sidelines of the Army-2022 International Military-Technical Forum about the prospects for the production and modernization of the PD-14 engine , the required number of PS-90A, on the development of the PD-35 engine and on the opportunities that open up for designers after its appearance.

“We have just signed a four billion ruble loan with Novikombank for the production of a very large batch of PD-14s for the next years,”informedAlexander Inozemtsev to the journalist of the TV channel Zvezda Alexei Samoletov during a conversation.

He explained that the required production volumes of the PD-14 are currently so large that this engine is not planned to be used anywhere except for the MS-21 liner. “God forbid to swallow what will now be on MS-21-310. [...] The government instructed us to reach 160 engines a year by the thirtieth year, this is with a reserve. There will be 72 aircraft [per year], plus a reserve,” said the deputy head of the UEC.

Regarding the line of promising engines and the modernization potential of the PD-14, Alexander Inozemtsev noted that so far this is the first member of the family. But there will be others with a thrust of 8 to 18 tons.

“Irkut Corporation is simultaneously making a smaller aircraft for an engine with a capacity of 12.5 tons instead of fourteen, and is now actively engaged in the “four hundred” - MS-21-400 . This is 16.5 tons and a larger aircraft,” said A. Inozemtsev.

Regarding the PD-8 engine, he said that the UEC-Saturn enterprise is developing it, and the UEC-Perm Motors is an "accomplice" in this project, explaining that the required number of these engines is about 100 units per year. "The Superjet needs to fly."

Answering a question about the succession of the PD-8 and PD-14 gas generators, Alexander Inozemtsev said that it was a mistake to consider the PD-8 gas generator as one of the PD-14 variants. “This is a brand new gas generator. It is smaller, more optimal for this small engine than the PD-14 gas generator and therefore a more technically risky project. The timing of its creation is very tough,” he explained.

Alexander Inozemtsev also noted that in addition to the PD-14 and PD-8, there will be a sharp increase in the production of PS-90A engines.

“Because the magnificent Tu-214 aircraft, ruined in the zero years ... the “leader” made a decision: to urgently make 70 aircraft before the 30th year. We reach 120 PS-90A engines per year. This is along with military orders. This is also a huge volume. This is an engine that got into trouble... We received a type certificate on April 3, 1992... And thank God that it comes to life and will be made in the same quantities as the PD-14,” said the general designer of JSC UEC-Aviadvigatel.

And depending on the engine, the undeservedly ruined Tu-214 comes to life - a medium-haul airliner capable of flying 6-7 thousand km non-stop, for example, from Moscow to Khabarovsk. Also, this liner is used for special purposes as a reconnaissance and surveillance aircraft. “The equipment has been preserved, the technologies have been preserved. Now you just need to remove the military cabin and put in beautiful seats, and there will be a magnificent passenger plane,” said A. Inozemtsev.

And the most important question that Aleksey Samoletov asked the Deputy General Director of the UEC: "What is the fate of the PD-35?"

According to Alexander Inozemtsev, in conditions of limited resources, unfortunately, the project will develop more slowly than previously planned. The PD-35 demonstrator engine will be assembled and tested by 2024.

“The PD-35 project will go a little slower, with a shift to the right for two or three years, because gigantic money is needed. Without a doubt, we will assemble and test a demonstrator engine by 2024, no matter how hard it is. And then let's move on to the situation. But we will understand for sure, having assembled the engine, where we are in terms of technology, we are creating technologies for the long-haul aircraft market,” said A. Inozemtsev. He added that the main forces will now be applied to replicate the PD-14 and PS-90A engines.

At the same time, the General Designer of UEC-Aviadvigatel noted that the PD-35 has great potential. “This is the most innovative project. The latest technology is absolute. This is a market niche for long-haul twin-engine aircraft, a colossal scientific and technical potential, which we must enter with the help of the PD-35 and further develop the family from 25 tons to 50 tons. This is what we are aiming for,” said Alexander Inozemtsev.

He added that China is very interested in the PD-35 engine project. “Now it will be easier with the pandemic, we will revive.”

it could not be the same as the thrust is just a bit more than half of the PD-14. The core would be too large for the rest of the engine and also highly inefficient. I believe the lower thrust limit for the PD-14 family engines is around 12.5 tons.

Maybe the new PD,8 engine will have better specific fuel consumption than the SaM146 engine (which, according to public available data has actually worse performance than the later models of the Soviet/Ukrainian Ivchenko -Progress D-436).

At the Technoprom-2022 forum, they talked about the timing of the development of the PD-8 engine, 08.26.2022.

As part of the development work and in order to pass the certification of the PD-8 engine, it will be necessary to manufacture and test nine prototypes. This was announced in Novosibirsk during the Technoprom-2022 forum by UEC General Designer Yuri Shmotin.

“Testing continues for almost a year. The gas generator of the engine, components and systems were tested. We need to produce nine prototypes and four assemblies as part of the development work. A large amount of testing lies ahead,” he said.

The General Designer of the UEC explained that it is planned to create and test the engines within the next year. All these works should be completed in 2023. He emphasized that it is necessary to confirm by tests the design results and the compliance of the engine with the requirements of the certification basis.

“The question is not to manufacture, but that we must confirm the design results with tests,” the general designer said.

Also at the forum, the head of the Department of Innovative Development of the UEC Evgeny Pavlovtoldthat the process of development and production of engines, in particular, VK-650 and PD-8, is planned to be reduced to four years.

According to him, one of the key tasks facing the UEC today is to reduce the time it takes to develop and bring products to market. “When developing such engines as the PS-90, the development period was about 12 years, the PD-14 engine is eight years, and at the moment we have a target setting to reduce the product development period to four years, these are our VK-650 and PD engines -8,” he said.

In turn, the head of projects of the highest category of innovative development of Rostec, Viktor Slavyantsev, noted that it takes about five years for UEC to form a complete advanced scientific and technological reserve before the production and development of an engine.

Here's a good article on current Russian turbine engine research areas. Demonstrators are being made to test polymer composite compressor rotating elements, ceramic composite turbine elements (probably static), dry bearings (no lubrication), and hollow discs. And it may not have a gearbox. Next gen technology.

What an excellent article... well worth visiting and giving them traffic:

CIAM develops technologies for small-sized gas turbine engines
08.09.2022, 13:17 270
Photo: CIAM

The P. I. Baranov Central Institute of Aviation Engine Building (CIAM) conducts research and develops technologies for advanced small-size gas turbine engines (MGTD) and aircraft piston engines (APD) to ensure the creation of mass-produced engines for light aircraft, helicopters and UAVs for civil purposes.

The results of the fifth, penultimate stage of the research work "Demonstrators of MGTD and ADF", ordered by the Ministry of Industry and Trade of Russia, were summed up at the Scientific and technical Council at CIAM in August this year, the press service of the Institute said.

The three-year research project is scheduled for completion at the end of 2022. The result of this work will be the creation and testing of five demonstrators: a" more electric " dry small-size MGTD, a promising low-cost MGTD, demonstrators of free-piston and turbocompound ADF technologies, a demonstrator of a high-altitude small-size combustion chamber, as well as a number of experimental objects: a compressor impeller made of polymer composite material, a turbine nozzle made of diamond-silicon carbide composite material, hollow disk of the MGTD turbine, etc. The technology demonstrators and experimental facilities developed and tested at V Zhelezye CIAM will serve as a base for the development of a new generation of domestic small-sized gas turbine and piston engines.

A number of innovations are planned to be introduced in promising Russian aircraft engines. So, the built-in electric generator of the" more electric " engine will provide power to the electric drives of its units. This allows you to get away from the manual transmission of drives and improve performance, reduce the weight and cost of the structure, and increase the reliability of the engine. The demonstrator is called" dry " because it uses supports with gas-dynamic bearings that do not require oil cooling. This will reduce the amount of maintenance during operation, as well as reduce the weight and cost of the engine.

"At the heart of the promising MGTD of low cost turbofan engine-200 is the concept of a unified gas generator, which reduces the number of parts to a minimum, combines the functions of structural elements," says Yuri Fokin, head of Research and Development, Head of the CIAM Department. – Due to the optimization of manufacturing technology, which involves the use of resource-saving methods and materials, the cost of such an engine will be significantly cheaper than traditional ones. Its scheduled inter-repair life is 2000 hours. This is not yet ROC, but our task is to bring the engine as close as possible to the serial, "business" model at the research stage."

The demonstrator of advanced ADF technologies is a turbocompound engine-a combination of a piston engine and a gas turbine engine.

"A turbocompound module is added to the piston engine, which uses the energy of the ADF exhaust gases in the turbine and converts it into mechanical energy, thereby increasing the engine power," explains Yuri Fokin. "The turbocompound module is being developed as part of a demonstrator paired with a basic 100 hp piston engine, but in the future it will be able to be used with different ADCs for UAVs and small aircraft."

Additionally, the characteristics of the piston engine are improved by using a volumetric air supercharger, which is part of the demonstrator of advanced ADF technologies.

The peculiarity of the free-piston engine is that in its design there is no mechanism-a converter of reciprocating movements of pistons in the rotation of the output shaft. This simplifies the design of the engine, reduces its weight, and increases the reliability of the power plant. Such engines are supposed to be used in conjunction with a linear electric generator as part of power plants for light-engine "more electric" aircraft.

As part of the fifth stage of research, demonstrators and experimental objects were manufactured and tested based on the designs and solutions developed at the previous stages. The results confirmed that the products met the requirements of the technical specifications for their development.

So it is a development programme to make small gas turbines and prop engines for light planes and helicopters and UAVs using new materials and new technologies and more electric components... this sounds excellent...

The first set of engine nacelles for the PD-8 engine was shipped to VASO, 10.13.2022.

The Voronezh Aviation Aircraft Building Society (VASO, a branch of PJSC Il) has shipped the first set of engine nacelles made for the new PD-8 engine. The flight kit of the PD-8 engine nacelle is a fairing, hull and wings, the customer is UEC-Aviadvigatel, the UAC press service reported.

“The work on the PD-8 project for the domestic SSJ-New aircraft was decided to be significantly accelerated,” says Alexei Moskovsky, head of the VASO composite production workshop. - The production was completely carried out at the sections of mechanical processing of parts, gluing and automated laying out, reconstructed under the federal target program, functioning on the principle of a "clean room".

All new products from non-metals and polymer-composite materials are manufactured at VASO according to electronic models on high-performance CNC equipment. Taking into account the extensive experience in working with engine nacelles for the PD-14 engine, domestic composites have been introduced and used at the aircraft plant.

Now VASO continues to work on the manufacture of the second set for the PD-8, intended for additional bench tests of the engine.

Promising engines for local airlines and small aircraft will be presented at MFD-2022

22.10.2022

Small-sized aircraft engines of various types and purposes will be one of the important topics of the exposition of the Central Institute of Aviation Motors named after P.I. Baranov at the International Engine Building Forum - 2022, the CIAM press service reported.

The stand will feature demonstrators of advanced domestic piston (APD), rotary piston, electric and small-sized gas turbine engines in the power range of 70-500 hp. The Institute is the lead executor of work on the creation of technology demonstrators for these engines, forming a scientific and technical reserve to ensure a smooth transition from research to development work and accelerate the transfer of products to mass production.

The single-circuit turbojet TRD-70 and the turbojet double-circuit turbofan engine TRD-200, with a thrust of 70 and 200 kgf, respectively, belong to the family of promising small-sized low-cost demonstrator engines developed by CIAM by order of the Russian Ministry of Industry and Trade. They are created on the basis of a unified gas generator, a feature of which is the number of parts reduced to a minimum and the combined functions of structural elements. CIAM will complete a three-year research project this year. Upon completion of the R&D, the engines will be able to be used on aircraft (LA) of small aircraft and local airlines.

Visitors to the CIAM exposition will be able to see the demonstrator engine APD-500 (power 500 hp), adapted by CIAM for aviation use from an automobile engine of the EMP FSUE NAMI engine line. R&D, which is also ordered by the Russian Ministry of Industry and Trade, will be completed this year. APD-500 has successfully passed a series of ground and altitude-climatic tests, incl. as part of the power plant of an experimental aircraft based on the Yak-18T. In the future, it will be able to be used for the remotorization of training and agricultural aircraft, as well as for advanced aircraft, incl. twin-engine.

Another piston innovation is the free-piston aircraft piston engine being developed by CIAM. The absence of a mechanism in the engine - a converter of the reciprocating movements of the pistons into the rotation of the output shaft simplifies the design, reduces its weight, and increases the reliability of the power plant. Such engines are supposed to be used in tandem with a linear electric generator as part of power plants for light-engine "more electric" aircraft.

As part of the development of technologies for the "electric" future of aviation, the booth will demonstrate the fault-tolerant 6-phase demonstrator electric motor ED-360 (power 360 kW) developed by CIAM for the power plant of a light helicopter. Information will also be provided on other projects being implemented by CIAM to develop technologies for hybrid and electric power plants, including work in the areas of "Intelligent Engine" and "Electric GTE", aimed at finding new effective methods of engine control.

The direction of rotary piston engines will be represented by the RPD-100T aircraft demonstrator, developed by order of the Advanced Research Foundation. The single-section RPD-100T of a block-modular design, equipped with parts made of composite materials and a domestic turbocharging system, has high specific characteristics, small dimensions and a wide range of operating conditions, which are confirmed by the results of resource and altitude-climatic tests at the CIAM stands.

CIAM is working not only on new design schemes, but also explores the use of advanced materials and technologies in engines of the future. At the booth, you will be able to see demonstrators of engine elements and assemblies, which use the latest solutions. These are, for example, a unified gearbox of a small-sized gas turbine engine, a hollow LPT blade with a shroud designed by the method of topological optimization printed by selective laser sintering; turbine nozzle segment made of diamond-silicon carbide material; "branched" heat exchanger and many other interesting exhibits.

Also at the stand will be presented demonstrators of elements of a promising power plant for a new generation supersonic passenger aircraft (SPS): a model of a flat nozzle turbofan engine with an ejector and shielding elements of the SPS airframe; supersonic spatial air intake and noise-reducing sector nozzle.

WFD-2022 will be held from October 26 to October 28, 2022 in the 57th pavilion of VDNKh, Moscow. The forum organizers are the Russian Ministry of Industry and Trade and ASSAD. Within the framework of the IFD, a Scientific and Technical Congress on Engine Building will be held.

The development of the PD-35 engine will depend on the work on the CR929 aircraft, 10.26.2022.

In August 2022, Alexander Inozemtsev, Deputy General Director of UEC JSC for the management of NPK Perm Motors, Managing Director - General Designer of UEC-Aviadvigatel JSC, announced at the Army International Military-Technical Forum that due to the upcoming loading Perm engine builders with the serial production of PD-14 and PS-90A, as well as participation in the PD-8 program and the corresponding redistribution of resources, the PD-35 program is shifting “to the right”.

Now in an interview with Vzlyot magazine, the general designer of UEC-Aviadvigateltoldon the nearest work plans for this promising turbofan engine.

“In the coming years, we will make a demonstrator engine and test it to understand where we are, how difficult and how long it will be fine-tuned. We will do it no matter what the circumstances. I think that in 2024 we will test it,” said Alexander Inozemtsev.

Also, according to him, the reconstruction of the PD-35 test bench will begin at the testing station in Froli. “We will build a temporary open stand there to test the main characteristics of the PD-35 demonstrator engine. And then, depending on the result, we will plan further fine-tuning. We will involve private small high-tech enterprises in this work. And, I hope, by the end of 2024 it will become clear to us how close we are to the necessary characteristics,” said Alexander Inozemtsev.

He noted that the PD-35 gas generator had already been tested , and the convergence of experimental and calculated data turned out to be much higher than that of the first PD-14 gas generator at one time. The characteristics obtained are very close to the design values, and UEC-Aviadvigatel hopes that the engine as a whole will show characteristics close to those that will ensure its competitiveness in the long-haul aviation market.

“We are still looking for sources of funding, since part of the money allocated for PD-35 is now being redistributed to other priority tasks. And this is right - it is necessary to clearly prioritize, it will not work to do everything at the same time, ”the general designer explained.

Further work will depend on the development of the SFDMS CR929 program. “... either cooperation with Chinese partners will continue, or it will be decided to modernize and remotorize the domestic Il-96-400, or some other option will appear. But for the time being, this is not so critical for us - it is now very important for us to master the technology and understand where we are, what we really managed to achieve, because such large engines have never been produced in either the Soviet Union or Russia", concluded Alexander Inozemtsev.

Three prototypes of the promising PD-8 engine have been created in Russia
Deputy General Director - General Designer of UEC Yuri Shmotin said that their tests will continue to be carried out in 2023

MOSCOW, 27 October. /TASS/. Three prototypes of the promising PD-8 engine have been created in Russia. They participate in trials. This was announced to TASS by Deputy General Director - General Designer of UEC JSC (part of Rostec) Yuri Shmotin at the International Engine Building Forum.

"We have already tested three prototypes, on which we obtained results, and today we say: thermodynamically, the machine has succeeded," he said.

According to Shmotin, work on the engine continues. He noted that there are issues that need to be resolved during the certification and engineering tests. Tests are planned before the end of the year and next year.

The PD-8 engine is being developed for the SSJ 100 aircraft and the Be-200 amphibious aircraft. The premiere demonstration of the gas generator of this engine took place at MAKS-2021, which took place in Zhukovsky near Moscow. The PD-8 concept is based on the creation of a family of modern gas turbine engines with the possibility of improving the specific fuel consumption and reducing the cost of the life cycle. Earlier, Vladimir Artyakov, First Deputy Head of the Rostec State Corporation, said in an interview with TASS that the promising Russian PD-8 engine would receive a certificate in 2023.

Which suggests they are not focused on Slon and twin engined Il-106, so presumably the focus is on civilian airliners and their engines that are also currently used by the Il-476 and potentially the Il-276 and Il-106 in the four engined version...

Interesting.

UEC held a presentation of the PD-35 engine. 10.27.2022.

At the International Engine Building Forum (MKD-2022), the UEC presented a model of a promising double-circuit turbojet engine of extra large high thrust - PD-35.

On October 26, Alexander Inozemtsev, General Designer of UEC-Aviadvigatel JSC, Deputy General Director for Management of NPK Perm Motors, made a presentation of the new product,toldin the editorial office of the Vzlyot magazine.

According to him, the project is now at the stage of research work, within the framework of which a demonstration gas generator PD-35 and its individual components have already been manufactured and are being tested, and a demonstrator engine will be built and tested in 2024.

Alexander Inozemtsev emphasized that for the first time in domestic practice, “we are conducting large-scale work without having a technical task from aircraft, but engine engineers from all over the world live like that.” The task of the current stage is to work out new critical technologies, due to which readiness for the start of development work will be achieved.

From the presentation of the general designer of UEC-Aviadvigatel, it follows that the PD-35 gas generator has a 10-stage compressor and a two-stage turbine. For the first time in Russia, a fan with a diameter of 3100 mm will receive blades made of polymer composite materials.

Achieving the specified parameters of the PD-35 engine requires the development of about 18 critical technologies, among which one of the key ones is a fan blade made of PCM. In 2020, Alexander Inozemtsev said that the transition from a solid titanium to a hollow titanium blade made it possible to reduce the mass of the assembly by 30%, and the use of a composite blade would save another 30% in mass.

In the presentation of Alexander Inozemtsev at MKD-2022, several options for extra-high thrust engines were presented. These are the PD-35 with a thrust of 35 tf for aircraft of the CR929 type (take-off weight up to 245 t), PD-38 (thrust 38 tf) - for possible remotorization into the twin-engine version of the Il-96-400 (weight 270 t, more than 350 passengers), PD -28 (28 tf) - for modernized and promising super-heavy transport aircraft with a take-off weight of 400-450 tons and a payload of 100-150 tons, PD-24 (24 tf) - for a promising transport aircraft with a payload of 80-100 tons, as well as industrial gas turbine plants GTU-20PD and GTU-33PD with a capacity of 20.4 and 32.7 MW.

The PD-8 engine is considered as the basis for the power plant of the Mi-26 helicopter
October 28, 2022 at 10:05 am Theme: Aviation , military- industrial complex
The United Engine Corporation has created three samples of the PD-8 engine. Its gas generator is considered as the basis for the engine of the world's largest Mi-26 helicopter.

“We have already tested three prototypes, on which we have obtained results, and today we say: thermodynamically, the machine has succeeded,” Yury Shmotin, General Designer of the UEC, told the media

According to the press service of Rostec, the Ministry of Defense of the Russian Federation is the customer for the engine for the Mi-26.

The PD-8 bypass turbofan engine is planned to be used in the SSJ-NEW passenger aircraft and the Be-200 amphibious aircraft.

Interesting fact, because in the past they spoke about using a PD-12V, derived from the PD-14, but while more efficient it would have been heavier of the Progress D-136 turbofan from Zaporozhye.

It make sense, also because the D136 turboshaft was derived from the D-36 turbofan, an engine less powerful than the PD-8 (6.5 tons takeoff thrust for the D-36 Vs more than 7 tons takeoff thrust for the PD-8.

However it will also mean that a new turboshaft (and later turboprop engine) of 8 to 11 kW will have to wait a few more years.

Note: an eventual PD-12V would have been in need to be derated in order to be paired with the Mi-26 gearbox, as the D136 has a maximum possible power of 8,500 kW (11,400 hp), while according to preliminary data the PD-12V would have been capable of more than 10500 KW (14000hp).

UEC increases production capacity in Rybinsk for the production of the PD-14 engine
07.11.2022

In 2025, a new production building will be put into operation at the UEC-Saturn enterprise in Rybinsk, where more than 250 machines will be installed. This will make it possible to increase the production of parts and assemblies for serial assembly up to 160 PD-14 engines annually by 2029.

UEC-Saturn participates in the development and production of power plant components as a co-executor and is responsible for the production of low-pressure compressor parts and assemblies, as well as high-pressure compressor stator blades.

At the moment, the production capacities of the cooperators are being increased and modernized, in particular, a new building is being built at UEC-Saturn, the total area of which will be 40,000 square meters. More than 250 units of equipment will be installed in the new workshop, including 102 new machines. In 2025, the facility will be put into operation, the press service of the Rostec State Corporation said.

In addition, the Rybinsk enterprise from 2027 will be the lead organization for the repair of power plants for MC-21. The deployment of repair production for the PD-14 engines is the final stage in the creation of the UEC competence center, which will also serve the SaM146 and PD-8.

"As a result of the implementation of the product program, by 2030 the total number of SaM146, PD-8 and PD-14 engines will exceed one thousand units. For timely and high-quality maintenance and repair of power plants, UEC will increase the capacity of the repair production of the Rybinsk enterprise to 250 power plants annually. To organize repair work with PD-8 and PD-14, the area of the workshops will increase from 10 to 16 thousand square meters, 27 units of new equipment will be purchased and the test base will be adapted", said the Deputy General Director - Managing Director of PJSC UEC-Saturn Victor Polyakov.

Note, the photo in the article is about a bench test of the NK32-02, which is the modernised tu-160 engine, and not about the PAK-DA engine, which currently is only know by the name "изделие РФ" (product RF)), and which characteristics (fan size, bypass ratio, etc) are currently unknown to public.

https://aviation21.ru/v-samare-proshli-stendovye-ispytaniya-dvigatelya-dlya-pak-da/

Bench tests of the PAK DA engine were held in Samara
31.10.2022, 12:34 1 233

Prototypes of the “RF product” engine for a promising long-range aviation complex (PAK DA) have passed bench tests. This is reported by TASS with reference to a source in the military-industrial complex.

“Several prototypes of the engine have already passed part of the bench tests, now the tests are ongoing, according to their results, we can say that the engine confirms the parameters laid down in it,” the agency’s interlocutor said.

He added that a special stand for testing was prepared for the “product of the Russian Federation”. At UEC-Kuznetsov, preparations are underway for the production of the engine.

Alexey Sobolev, Deputy General Director - Managing Director of UEC-Kuznetsov, spoke about the assembly of the first engine for PAK DA in December 2020.

In 2021, the Russian Ministry of Defense was reported to have approved the final look of the PAK DA. Priority is given to reducing the visibility of the aircraft and weapons with a long range of destruction, and the construction of several prototypes of a promising aircraft is also underway.

PAK DA is designed according to the "flying wing" scheme with subsonic flight speed. The design of the new strategic missile carrier will make extensive use of technologies and materials that reduce the radar visibility of the aircraft. It will be capable of carrying existing and future long-range cruise missiles, high-precision bombs, hypersonic weapons, and will be equipped with modern means of communication and electronic warfare.

A previous article from December 2020 said that

The Samara engine-building company "ODK-Kuznetsov" has started developing a gas generator for a 5th generation engine in the 18-24 tf thrust class. The new engine can be used for advanced long-range and military transport aircraft - PAK DA and PAK VTA. Research work is planned to be completed by the end of 2022.

https://aviation21.ru/odk-kuznecov-razrabatyvaet-gazogenerator-dlya-novogo-perspektivnogo-dvigatelya/

Since PAK-DA is a subsonic aircraft and the engine should be without afterburner, the engine (of course with new pylon and nacelle) should be also usable as a replacement for the D18T in the An-124 (or possibly in an eventual il-106).

This engine should end up being on the same thrust class as the PD-24, that however will not probably be available before mid 2030s.

Very interesting:

> This second stage would be probably a 5th gen development based on the NK32, but with that application and thrust class it should have a substantially higher BPR than current engine. If that was the case, the PAK-DA's fuselage should be designed with the ability to house bigger engines, or rather, ones with a smaller core but higher BPR
> Given the thrust class, which is already in line with current NK32 capacities, maybe the core of development is not to achieve much higher performance, but rather reduce the big stage count of the current engine and/or consumption by increased BPR and reduced core size;
> Also possible that the core could serve two different designs with different BPR and different applications;
> The biggest threat to the feasibility of this engine is that it would compete with the downsized version of the PD-35 that was announced recently and would also provide that thrust level (PD-24), but that one would already demand to reduce the BPR very substantially or a strong reduction of the core size. We saw that already with the PD-8 derived from the PD-14, so it may be possible.

At first I would guess this is an own-initiative project by Kuznetsov and not an order of the military but, looking deeper, maybe VKS favors to have specially designed, military grade engines in their fleet instead of simply using those designed for civilian applications. In which case VTA and Long Range Aviation may stick to Kuznetsov products for the future. The released characteristics of the izdeliye-RF (like flight endurance, temperature range and EMP hardening) point in this direction.

This is needless duplication of resources IMHO. You basically will have three engines in the same thrust class. The NK-32-02, this Izdeliye RF, and the PD-35. There is no good reason why these engines would not have at least a common gas generator. Because of all this duplication then the industry lacks resources and some projects get defunded and cancelled or close to it. The PD-35 is already getting a cut in funding.

NK32 and izdeliye-RF are essentially the same Kuznetsov engine, with some new parts and the afterburner being removed in the later. The further development of this type would be the 5th gen gas generator discussed in the link above, which should not be a redundant path, but the substitute of the NK32.

PD-35 is in a different thrust class altogether, unless they reduce substantially the core or under-use it in a 24 tf class application.

So there would be no duplication, Kuznetsov would fill the gap between the PD-14 and the PD-35, and ensure VKS gets engines designed specifically for military applications in the right power classes. Does not seem unreasonable to me, and the investment of substantial amounts of money in reestablishing production of the NK32, modernizing the engine, plus giving the PAK-DA order to Kuznetsov, indicate that the military are interested in keeping them as a supplier, at least for the long range aviation.

The PD-35 is being delayed a bit to use funding more efficiently.

If they want real stealth and to carry very long range weapons on the PAK DA and also be able to use bombs then I would say optimisation for very high altitude flight with engines that might sit on the back (top) of the wing so it is stealthy from ground based radar and airborne radar...

Having different engines could also offer the potential for a future flying wing with semi tail surfaces and thrust vectoring nozzles on the engines to allow transonic flight performance and potentially super cruising too... if they are flying high then the speed potential is increased and drag reduced so why not take advantage of that with super cruising so it moves around the place faster without excessive increases in fuel consumption.

Civilian aircraft that could do the same would be useful too, for very long range flights.

Rostec to Double Production of Engine Components in Samara
November 16, 2022

The Rostec United Engine Corporation launched three new production buildings equipped with modern equipment at the Samara enterprise UEC-Kuznetsov. More than 4 billion rubles have been invested in their construction. The commissioning of new capacities will double the output of components for a number of power plants, including NK-32 series 02 and Izdeliye RF.

Vladimir Artyakov, First Deputy General Director of Rostec State Corporation, and Alexander Artyukhov, General Director of the United Engine Corporation, took part in the opening ceremony of the new tool production and welding buildings, as well as the second stage of the compressor production building.

"The implementation of the largest investment program in the history of UEC-Kuznetsov in the amount of 40 billion rubles allows us to significantly increase the company's capabilities. 12 new facilities have already been built and are in operation, and 9 more are at various stages of construction. After the commissioning of three new production sites with a total area of almost 11 thousand square meters, in the construction of which more than 4 billion rubles have been invested, the Samara plant will be able to double the volume of production of engine parts with significantly lower labor costs. Thanks to the installation of 69 units of modern equipment, it will be possible to significantly speed up production processes. I would like to note that some of the high-precision machines required for production are manufactured and supplied by Rostec's machine-tool companies, in particular STAN, " said Vladimir Artyakov, First Deputy General Director of Rostec.

All sections of the new production facilities are equipped with high-precision control equipment – coordinate measuring machines, magnetic powder and luminescent control, which allows you to track the quality of products at all stages of production.

"Until the end of 2022, the new sites will be used to manufacture parts within the framework of the UEC-Kuznetsov aviation, missile and ground-based programs. The introduction of new production sites will have a positive impact on the production performance of our company, " said Alexander Artyukhov, General Director of the United Engine Corporation.

The new tool production site with an area of 2.4 thousand square meters will produce tooling and tools intended for assembling parts and assemblies of a number of industrial engines, as well as aircraft power plants NK-32 series 02, NK-12MP, NK-25 and a new promising high-power Izdeliye.

The 3.9-thousand-square-meter welding building contains nine sections with equipment, including robotic equipment that allows operators to automatically conduct soldering, welding and applying protective coatings. The technological chain includes a 3D printing unit for "growing" large-sized products. The production facility is capable of processing more than 5,5 thousand parts and assembly units per year.

The second stage of the compressor housing with an area of 4.6 thousand square meters includes 11 sections, including mechanical processing of compressor parts, plasma and detonation spraying, and quality control of parts. Lathes and grinders, processing complexes, robotic spraying units, magnetic powder and fluorescence monitoring units were purchased to equip the site.

A new site for the production of VK-650V and TV7-117V engines was launched in Moscow
01.12.2022

The United Engine Corporation launched a new production site at the MMP named after V.V. Chernyshev for the production of VK-650V and TV7-117V helicopter engines. At the new site, the process of manufacturing one of the most complex parts of a high-pressure compressor - a centrifugal wheel, the most important part of an aircraft engine compressor, has been worked out. Until 2025, it is planned to increase the production of compressors up to 500 units annually, the UEC press service reported.

The new production site has become part of the center of specialization of the compact production complex "Production of DSE helicopter engines". It made it possible to create a technological reserve for the production of components for promising helicopter engines VK-650V and VK-1600V. More than 130 units of new equipment have been placed on the site.

“Today we are opening a production site, an important “fragment” of the engine corporation's new production model. The created site is part of the center of specialization of the compact production complex "Production of Helicopter Engines DSE", which, in turn, is implemented by the UEC as part of the transformation of the industrial model," said Valery Teplov, Production Director of the UEC.

When creating the site, fundamentally new approaches and solutions were used - this is the simulation of production flows in a digital environment, the use of digital transformation tools, for example, equipment loading control, modern machines are involved, taking into account lean manufacturing and building the production flow for manufacturing parts. An electronic document flow of technical documentation has been introduced, and a project on electronic planning is being worked out.

“Creating a new site, we are creating a high-tech production complex at the enterprise. This is part of a large project to transform the UEC production model. The site will expand bottlenecks, provide an increased production program for the manufacture of parts and assembly units for VK-2500, VK-1600 and VK-650 engines,” said the managing director of the V.V. Chernysheva Amir Khakimov.
