New combat aircraft will be presented at MAKS-2021

I guess, there is no point to discuss that further until we will see in "naked"
If that thing would require so big air intake, it would mean that engine is much more powerful than we have ever expected.
My suggestion is, let's live it for a few days

Rememer what was promised at the beginning of the F-35 program. The plane will be ready very fast and be cheap because all the tech has already been developed for the F-22. In the end they invented the wheel new, so to say. It seems the russian developers did exactly that, developed all the stuff for the Su-57, took some to build the Okhotnik and now this nice "little" plane. Of course, our western friends and partners will claim that it could only be done because the evil russians stole all the stuff from poor american companies.

The next days and weeks will be very interesting to watch.

Will they announce ROFAR?
What other technologies

I dont know about ROFAR if it is even a possible presentation or if it would be on the 2nd version Su-57 which is tested in 2022-2024 so maybe maks 2023 or 2025 airshow if we get lucky? I want the air to air/ground weapons the most or some features mentioning the avionics of the Su-70 atleast. More TEM projects will make me happy to.

KRET clarified recently what we have been saying, that ROFAR is at the level of basic research, that means, decade(s) away from implementation.

IMO that plane will be a flying S-70 with a pilot and a design of a fighter. That's why it is fast to build. All the systems will be the same.

in other words like a pulse detonation engine

It sure was mean of VEGA displaying those antennas and RTI stating in September 2019 that in a few years a prototype aircraft will have.

We will have to wait for a week, to see it without cover. This cover is baggy to hide its details. But what could be seen uncovered is, that the plane is painted and looks very refined. Maybe this is not even the first prototype. We do not know, how long they develope it, maybe even longer than S-70 Ohotnik and at what stage it is. If it have electronics installed, as IRST, radar, etc, than it could be later stage prototype. First prototypes for static tests and for learning to fly doesn't need combat electronics and is usually not that refined and even without RAM (Su-57 first prototypes). If it is later stage, than it for sure made its first flight. After all, they bring to MAKS real plane, not a model.

It's interesting, that all western spy agencies as CIA, MI6,... didn't notice this plane before. Sukhoi kept it secret and made a surprise.

They were supposed to make three versions of one plane

Instead they decided to make three completely different planes that had to look the same

That's where it went tits up

I said months ago that MiG should take existing parts, a single engine and wrap them in new stealth airframe in order to develop new fighter jet

At the time I was ridiculed by several individuals here

But now Sukhoi did exactly that and took MiG's entire market segment

And the only one that will probably be substantially different is the Russian one

Broski wrote:If this plane finds success on the export market and the VVS adopts a domestic version for its airforce, where would that leave the MiG LMFS? Would they even have a need for it anymore?

I think it's safe to say that MiG LMFS has already been left behind, current day VKS has no patience for redundant products

LMFS wrote:...And the only one that will probably be substantially different is the Russian one

No horizontal stabiliser, it's already substantially different

Mig last chance is mig-41. If the program is late or not respecting the specs then it will be eaten by sukhoi.


I guess this one will be named su-21 in ref to the year but also to the wonderful single engine mig-21.

Certainly, there have been countless names for the Russian light fighter. It makes as much sense to develop LMFS in parallel with the LTS as to develop the MFI together with the PAK-FA. That is, below zero.

I will have to change my name here, but that is ok as far as we have a real plane FINALLY

I am pretty sure it will not be the only thing. The intake, TVC, and hopefully the bays are radically different, and many other solutions look like they are going to be unique. If Sukhoi manages to deliver, it will be the first proper and balanced realization of a "light" 5G fighter platform.

Because they are in the business of denial now. They only look for things that they want to find.

They are all under one roof now. For all we know, people with Mig on their paychecks could have designed parts of this aircraft.

Do we know with 100% certainty that it will say Sukhoi on the serial plate on this new bird ?

When did you start specializing in the LMFS ? What did you think the chances were that we'd see it come into existence ?

Regarding Klimov, this is from today's interview to UEC and it is difficult to say more with less words:

Secondly, a new generation of engines is being developed. The UEC's portfolio of ongoing developments includes new power plants for strategic and front-line aviation. A serious product fork is the question of developing a new generation engine to replace the RD-33/93. In my opinion, this is an important and promising product niche. A number of new twin-engine platforms are currently being developed around the world, focused on engines of this size. We do not see such a promising platform in the plans of our key internal customer yet. But in any case, in order to make an informed decision about the development prospects, it is necessary to study the appearance to clarify the technical and economic characteristics of the product.

They are saying now that it is a form of flattery, or that the design is copied form the F-35, or that it is a mix of F-22 and YF-23 thirty years late... while they buy F-15EX, retire the F-22, fail to field the F-35 and dream about a clean sheet 4.5G substitute for the F-16. Let us see the hysteric reactions when the ventral intake and the rest of the layout is revealed... Retard has become a high form of compliment for these arrogant no-brainers

Exactly, they will cooperate. Of course it seems that the honour of being the creator of the concept will not go to MiG, but they will have work and they will be able to recover. To what extent they get politically dominated by Sukhoi is an open question and depends on the government.

I started thinking about this I guess in 2017, I figured out that I could not solve my doubts (is it possible to create a true multirole light 5G fighter based on a izd. 30 sized engine?) without getting hands on and doing a 3D dimensional check myself, which ended as the model that has been circulating around. I knew the idea of a light single engine 5G fighter made tons of sense, but I am truly surprised that UAC has managed to keep it under wraps for so long while deep, concrete work was being developed. Not that I doubted they were checking the concept, but I admit how far they are with the design has caught me by surprise. Hats off to them for keeping it secret as they must. The resemblance of what I did and what we know until now is very nice to me, but I still want to wait the the 20th to see how the story ends

Backman wrote:Is it possible that its a whole new engine ? I hope  not. But doesnt it seem too big to be built around a su 57 engine ? I thought it would be more practical to be a little smaller.

That seems to be the main question about this aircraft. It does appear to be rather large when you look at that one pic with the bald man walking next to it. The girth is there even though the sagging tarp could have some effect on that, but the length is undeniable and it is pretty long, almost appears to be as long as the venerable Su-57.

So the engine is a huge question mark. Will it be a single Al-41 or is the Izdeliye 30 ready and is already in there and would either of those give this thing a thrust to weight ratio of greater than 1 and a top speed of around Mach 2? Or is there a new engine that has been built especially for this thing?

There was also a report that it would have TVC which I thought was interesting considering we've never seen a single Russian aircraft with a single engine that was also 360 degree TV. Some neat things to look forward to.

Oh, and also it's designation will be neat to find out. And let's hope NATO behaves itself this time and not come up with a stupid and insulting name like "Felon" those bastards.

It is not so sure whether it is a prototype or a mock-up.

How are we so sure this thing has no horizontal stabilizers? Maybe it wasn't added yet when the pictures were taken?

Tingsay wrote:How are we so sure this thing has no horizontal stabilizers? Maybe it wasn't added yet when the pictures were taken?

Maybe russian TVC technology is so advanced that they decided they dont need stabilizers, thus reducing drag. This raises the question if the TVC is 3D or 2D, and what benefits does 3D TVC add to a single engine fighter. My theiry is that 3D tvc adds diminishing returns for a light single engined fighter in terms of lower controllability compared to 2 engined fighters but more weight and cost. Therefore 2D system might be enough.

Currently the only air force operating a single engined fighter with TVC is the PLAAF with the J-10C. It would be interesting if sukhoi snalyzed the J-10Cs performance to see if TVC for one engine is worth it.

However, if sukhoi is like the people on this forum, they will deem all chinese engineering decisions as retarded and worthless because ofcourse, chinese are supposedly backward commie copying subhumans not capable of innovation...just like the west claims.
