When the world gives you lemons... make lemonade....

Make the best of a bad situation and turn it to your advantage... sounds like a good plan to me.

1) MS-21 is the first aircraft of its class to use a fully composite wing.

2) UAC is using vacuum infusion to assemble this wing from Russian made composite materials. Neither Boeing nor Airbus
have this technology. They use autoclaving and cannot make a full wing as one part and require assembly from smaller parts
which makes the whole assembly weaker.

3) There is no production delay of MS-21. This includes supply of PD-14 engines.

Awesome....

Nice , They should have also opted for all composite fuselage not just the wings.

That's too radical for the market. Acceptance of composites is a gradual process.

Lets see how the wings go first... this is largely unproven technology here... they need a lot of testing before they think about making all composite aircraft...

The Ministry of Industry and Trade has opened a tender for the concept of a civil supersonic aircraft

MOSCOW, April 15 - RIA News. The Ministry of Industry and Trade of Russia has announced a tender for the development of the concept of a supersonic civil aircraft (GHS) for almost 718 million rubles, the work is planned to be carried out in 2020-2021, according to the data of the government procurement portal.

"Scientific research work" A comprehensive scientific and technological project for the development of a scientific and technical reserve to ensure the creation of the CGS-T1 cipher supersonic civilian aircraft, the procurement statement states. The customer expects completion of work by December 15, 2021.

The ministry is ready to allocate up to 718 million rubles for development, indicating the corresponding maximum price for the contract. Of these, 213 million will be allocated in 2020, almost 505 million in 2021.

It is noted that at the moment in Russia there are no unified approaches to the formation of the appearance and life cycle parameters of a new generation of GHS.

The existing scientific and technical backlog in the interests of creating the GHS is not enough, which does not allow us to begin development work on the creation of a new generation of GHS. Significant technical risk, as well as the lack of standards for the acceptable level of sound shock and noise in the airport area, require development, numerical and experimental testing of new technical solutions and technologies, "the documentation says.

Carrying out research work in this direction will solve the problem, the ministry is sure. “Formation of a coordinated technical concept and a program for creating a GHS that ensures the competitive availability and quality of aviation services, with the fulfillment of promising requirements for environmental impact and safety based on the development of a set of key technologies,” the purpose of the work is described in the documentation.

Applications for participation in the competition are accepted until May 18. Received proposals will be considered in parts - May 19 and 22.

Well, tu-160 is restarting production. And there was supposed to be a civilian Varian as well. So why not? Ideal for within Russia flight

With new experience with ramjets and scramjets and of course new high temperature aluminium alloys it might be a good time to reexamine the idea of a supersonic civilian aircraft.

I actually liked the old designs shown for the T-4M... effectively a flying delta wing shaped bomber with small swing wings to reduce runway length.

With upgraded 5th gen versions of the NK-32 for the Tu-160M2... perhaps a thrust increase to maybe 30-35 tons per engine but maybe a 25 ton thrust level in dry thrust they might be able to make a civilian airliner that can super cruise at mach 1.8 to mach 2 perhaps without after burner... that would allow enormous range improvements and reduce fuel burn for longer trips.

Problem is that I can't see the western 1% flying on a Russian plane for any reason... which is fine... screw them...

Import Substitution Contract in the Design of the MS-21 Aircraft

After this is a table of items and dates that I can't translate.

Contract for import substitution in the design of the MS-21 aircraft
bmpd
May 7th, 17:33

As follows from the website of the Unified information system in the field of procurement, the Ministry of industry and trade of the Russian Federation on April 28, 2020 signed a contract with JSC Irkut Corporation as the only contractor for R & d on the topic "Performing research and development work in the framework of the project to replace imported materials and products in the design of the short-and medium-haul aircraft MS-21 with domestic analogues", the code "MS-21 import Substitution 2020-2021". The cost of the contract is 12.0763 billion rubles, and the deadline is December 31, 2021.

According to the contract documentation (the text of the contract), by the end of 2020, the contractor must select Russian-made materials and work out the technology for manufacturing MS-21 units from them, including the wing consoles, centerplane, Elevator and directional rudders, and tail units. It is also necessary to replace units, components and systems with domestic ones, prepare a test bench for their testing, and complete the production of a prototype No. 0012 of the import-substituted MS-21 with Russian PD-14 engines.

By the end of 2021, we need to continue R & d, including testing the technology for manufacturing composite materials based on carbon fibers produced by UMATEX (part of Rosatom). The result of the work should be the completion of the MC-21 prototype with import-substituted units No. 0012 and certification tests of this aircraft.

In General, the program of import substitution in the design of the MS-21 aircraft is designed for 2019-2024. It is worth noting that judging by the notes in the contract text (with the number "-300" crossed out in the index), the import-substituted MS-21 will no longer be designated MS-21-300.

In Russia, the demonstrator of a supersonic airliner may appear in 2023

A prototype demonstrater of a new generation of supersonic civil aircraft may appear in 2023 on the basis of the MiG-29 fighter, said Director General of the Central Aerohydrodynamic Institute (TsAGI) Corresponding Member of the Russian Academy of Sciences Kirill Sypalo in an interview with RIA Novosti.
“According to our calculations and with the availability of funding, such a demonstrator should appear by 2023. Obviously, this experimental aircraft is cheaper and easier to make on the basis of a donor aircraft, since the main goal is to verify in the flight experiment the correctness of the selected critical technologies: aerodynamic shape, the location, shape and size of air intakes, nozzle devices, etc., "said Sipalo.

Of course, you can’t talk about a full-fledged supersonic business aircraft, it is rather a prototype demonstrator," said the TsAGI general director.

interview with a RIA observer News Alexey Panshin was told by the Director General of the Central Aerohydrodynamic Institute (TsAGI) Corresponding Member of the Russian Academy of Sciences Kirill Sypalo .

None of these announcements are mentioning ozone layer destruction by NOx and other jet exhaust pollutants. That is what stopped
the planned fleet of supersonic civilians aircraft in the 1980s and 1990s.

These plans will go nowhere if they have not solved this problem.

I thought the problem with the ozone layer were CFC refridgerants...

Plus I would call a civilian aircraft based on the MiG-29 more of a private jet rather than an air liner...

In terms of aerodynamic shape the MiG-29 is a decent one to start with I guess... short operating field air strips but able to fly at mach 2.3 if needed... better and lighter and cheaper than a swing wing design of the previous generation.

Just to demonstrate some characteristics, the project is for a supersonic airliner.

CFCs produce ClOx which is one family of chemicals for catalytic destruction of O3. NOx is another family for
the catalytic destruction of O3.

Also, there is a fundamental chemical regime transition above 16 km where so-called pollution chemistry stops.
So in the troposphere NOx contributes to formation of O3 but in the stratosphere (above 16 km) it contributes
to destruction of O3. The reason is the concentration of atomic oxygen (O instead of O2) which is very reactive.

Operating a fleet of stratospheric supersonic cruisers which would fly above 16 km (Concorde flew above 18 km)
would inject NOx on an ongoing basis in a way that the current subsonic fleet does not. Subsonic civilian aircraft
cruise at 11 km.

It would be the low latitude flights that would be the worst since they would inject NOx into circulation pathways
that would efficiently distribute it to high altitudes (the stratosphere is characterized by a global meridional circulation
with ascent over the tropics and descent over the poles).

Well aren't there ways to prevent that... does natural gas fuelled aircraft produce the same level of the problem gasses.

And to be honest I don't see why these aircraft can't routinely fly at 15km altitude... the MiG-29 doesn't spend much flight time above that altitude normally... the max ceiling of the 29 is about 16-18km depending on the model.
