In OAK have told at the expense of what optimized SU-57
United Aircraft Corporation has noted importance of new methods of mathematical modeling.

Digital design has allowed to change significantly process of production of planes, to carry out besstapelny assembly of units of a glider and their automatic joining, the president of PJSC OAK Yury Slyusar following the results of the message of the president has told Federal Assembly.

"Use of domestic supercomputer technologies for mathematical modeling of the gun SU-57 installation has allowed to reduce the term of work on a design for many months, to save tens of millions of rubles" — he has told.

Besides, use in some SU-57 components of means of topological optimization has allowed to reduce the weight of difficult details of the fighter by 15-20%.

According to Slyusar, in the nearest future the corporation will enter digital technologies of augmented reality into practice.

"Their introduction on civil programs will lower time for assembly of difficult cable system for 25%, at the same time the quantity of mistakes will decrease twice" — he has emphasized.

In further OAK due to application of mathematical modeling plans to reduce natural tests of aerodynamic characteristics of products, verification of their strength characteristics, the onboard equipment, control systems and modes of fighting application.

And probably weapons separation trials. The left side of the radome has been painted with calibration stripes and the aircraft fitted with hardpoints.

It´s damn time!

In that last photo what is the IL-76 behind it with both a prop and a jet on the wing?

It's a testbed for testing new engines. So yeah it has two different engine.

Would be intersting to know if the prop is a new one and for which aircraft it is made. Or maybe it's an old plane that was left there with an old engine being tested.

Edit: google Il-76LL from Gromov flight research institut.

If I am not wrong this is the testbed for the TV7-117ST, the engine for the new light transport Il-112V

Another excellent pic of the T50-055, march of this year:




Edit: was not sure when I saw them at first but other people confirm that what the plane shows are eight war mission stars (!?)

Propably weapons tests.

The first stage engine for the PAK-FA has completed the state trials:

Tests of the engine for the SU-57 fighter are complete

The total meeting of the state commission on AL-41F-1 has come to the end with solemn delivery of PJSC UEC-UEPA of the act of completion of the state bench tests of the skilled engine, it is said in the statement of the company.

   "AL-41F-1 performs function of the engine of the first stage for the fighter of the fifth generation of SU-57 (PAK PHA). The first test flight PAK PHA with AL-41F-1 has taken place on January 29, 2010", - have reminded in UEC.

The program of the SU-57 fighter (PAK PHA) provides creation of the first serial samples with the AL-41F-1 engine of the first stage. From the engine for SU-35S (product 117C) him is distinguished the increased draft force, the difficult system of automation, completely digital control system, the new turbine and the improved account characteristics.

The engine of the second stage (product 30) has to provide to the fighter the cruiser supersonic speed, higher maneuverability, flying range. The first flight of SU-57 with this engine has taken place in December of last year. ■

--> So it seems they are getting ready to sign the contract for the first squadron and start deliveries next year

Will product 30 engine be as long to become operational?

Yup. this is a strong probability so we are looking at around 10 more years of testing, by 2030ish hopefully we will witness the official introduction of Su-57
Even Russia's UAV programs are running at the same pace, i mean they have been working on these projects for more than a decade and until now they still rely on Israeli "Forpost" Dont get me wrong, I didn't suddenly turned anti Russian, but the slow pace of these projects is a big disappointment.

Well they seem to have other priorities for their money which should be good news for everyone interested in peace. Modern weapons systems are quite complex and take ages to be completed, even among the supposedly rich countries (Eurofighter anyone? JAST then JSF to produce the F-35 like 25 years later?) These are multi-decade programs almost without exception.

What Russian officials have said is that Product 30 has already been designed, prototypes have been built and bench test has been ongoing for some time now. They were expecting at least three years more of testing until going in series, but since they do not seem to be in a hurry I would conservatively assume 5 years more before serial production of the engine. In the meantime one or maybe two squadrons of Su-57 can go operational and doctrine for its use can be developed. With the Su-35 and other existing aircraft the Russian Federation can take care of realistic conventional threats in that time frame, bigger threats (namely massive, frontal USA attack to the Russian territory) would mean nuclear war so no point in crushing the own economy trying to out-spend the whole NATO for a conventional war, me thinks.

The Su-27 took nearly 20 years.

You're off yer tree buddy....  its 2018 FFS, and you think the Su-57 won't reach IOC for another 12+ YEARS?

Fuck off and don't be a total prat. Saying shit like that is an insult, its suggestive that we are all stupid children with an inability to think critically, and I'm taking objection to it.

BTW the Ruskies already use a lot of drones for surveillance, arty targeting and observing strikes by stand-off weapons , and just because they haven't made been procuring USAF-style weaponized drones for whacking insurgents in 3rd-world shitholes doesn't mean they are "behind" - they simply don't have the same priorities as the Muricans, and have better and more important things to spend money on (like Khinzhal, Zircon, Sarmat, Avangard, Kanyon etc etc etc).

Not sure how you figure that.... The Su-27 program began around 1970 as the USSR came to grips with the prospective F-15, and first prototype flew in 1977. IOC was achieved in 1985.

I guess you can figure 20 years if you consider the time from initial inception to widescale service (ie late 80s) but its a real stretch.

The PAK FA was initiated around 2002 after award to Sukhoi, with 1st prototype airborne in 2010. I would judge that if the RuAF really wanted it, the Su-57 could make IOC in a year or so, albeit with interim engines.

However, the reality is that Su-35S and Su-30SM fulfills most of Russia's needs, and her SAM systems are proving to be as capable as HATO feared (Syrian operated export model Buk-2M and Pantsir are performing well in Syria, and really frustrating the NWO cartel-globalists who are not used to their wunder-waffens being shot down by their intended mugging victim...). Unlike the US, Russia has no burning need to rush 5G stealth warplanes into service, so they will work steadily at their own pace according to their own objectives, and pitiful whining by Westerners about what Russia isn't doing is just a useless exhalation of hot air...

The state bench tests of the AL-41F-1 engine have been completed

As reported in the press release of United Engine-Building Corporation JSC , the final meeting of the State Commission for the turbojet engine AL-41F-1 concluded with the solemn presentation of the PJSC "UDK-UMPO" (part of the United Engine Corporation of Rostekh) to complete the state bench tests an experienced engine. The ceremony was held in the Moscow branch of the enterprise - the Experimental Design Bureau. A. Lyulka.

Chairman of the State Commission Colonel VA. Bruskov handed over to the general designer-director of the OKB im. A. Lyulki E.Yu. Marchukov the document testifying to the end of the most important stage in the development of AL-41F-1.

Thus, 14-year experimental design work is completed. The AL-41F-1 performs the function of the first stage engine for the fifth-generation fighter Su-57 (PAK FA). The first test flight of PAK FA with AL-41F-1 took place on January 29, 2010.
