PAK-FA / Sukhoi Su-57 - Updates and Discussions

AMCA will have 5 prototypes, most probably they know this so may be they will test it with different engines. The only issue with the RD33 is the low thrust. Of course you can test it but then super cruise capability needs to be considered.
Under actual combat conditions, the thrust of the RD-33 engine far exceeds that of the 404, 414, and M88;
in fact, the MiG-35 likely boasts the highest thrust-to-weight ratio among active-duty fighter jets—surpassing even the Su-57 or F-22.

But Mig 35 doesn't have a true super cruise capability, may be at high altitude but not overall. High TWR means good acceleration but sustaining high dry TWR is a complete different subject. Dry TWR greater than 1.0 at trans-sonic speeds immediately shows a wave drag spike (increase in wave drag) on graph.

But we can't tell if AMCA with it's aeroprofile can supercruise on two RD33 engines, it will be interesting to test it. Rafale can supercruise on two M88 which means here some different parameters apart from TWR are involved.

AMCA Mk1 is not gonna have supersonic capability with the GE 414 engine anyway, might as well go with a reliable supplier if things don't go well as planned with America.
 
listen man. The Su57 isnt going to happen until and unless russia agrees to a ceasefire in ukraine, the economic issues of working with russia while the majority of our economy does trade with the west is too hard. The only way we get the su57 is if the PAF gets the J35. Then we have a credible case. Its not like we can do jackshit vs China anyway for the next 20 or so years.

Isn't Pak already getting J35?

I think we Su57 can be a good opportunity for Indian aircraft companies. But only if we can structure deal right. My ambition is that we structure the deal as deep MKIzed version, so that instead of buying any flyway units, we ask for progressive indigenisation of subsystems of Su57, based on the Super Sukhoi upgrade.

Something like using the Russian airframe and engines, but replacing some parts such as Radar with Virupaksha, weapons with Astra series, use HAL mission computer, DRDO ECM package, etc. Any other component such as IRST which isn't ready should be Russian, as we don't want to delay procurement.
As more and more components are developed, the future aircraft will see increased indian content.

I know a deal like this is only fantasy, but if MoD can pull it off, it will really give a huge push to indian aircraft industry.

I have repeatedly made post regarding the selection of engine. The AMCA need to have supercruise capability if they are serious about developing a 5th gen stealth fighter. Mk1 and Mk2 both must have this capability.

I am now more satisfied that you need atleast 45 Su57s now.

Unless until some heavy losses during war occurs the Indians don't wake up. 600 causalities in Kargil could have been avoided as well. In the name of bhai chara and contacts and reference useless and incapable fellows are sitting on our head and pissing from there.

Why? Even for America, the F22 is the only US fighter which can supercruise and it's already outdated for modern combat, none of our enemies possess jets which can supercruise, so why the fixation for it? Sure it would be good to have and we will likely get it for the mk2 where newer platforms will be released globally.

I love the Su57, it would be our equivalent to the F22 but a generation ahead in tech and is also multi role which is a huge bonus. It's the only relevant 5th gen right now which can supercruise.

India disappoints both optimists and pessimists at the same time, a strange wonder.

We do not have access to intelligence report that Chinese do not have any aircraft or can't procure one or develop one with super cruise capability. But it is known that J20 has the supercruise capability. And looking at the US Iran and Russia Ukraine skirmish, plus having two enemies in the vicinity you have to be one step ahead.

The J20 can't sustain supercruise with their interim engine I believe, not to mention the tons of other issues on the jet. Maybe they would be able to crack it with the WS15 engine.

Ideally I would wish for a lot things in the AMCA like 6 IWB capacity, supercruise, thrust vectoring but none of this are an absolute need for 5th gen needs.

China Expanding Serial Production of J-20A Long Range Stealth Fighters with Enhanced WS-15 Engines


New footage released on Chinese social media has shown a J-20A fifth generation long range air superiority fighter still in yellow factory primary, indicating it has been produced recently, integrating twin WS-15 next generation turbofan engines.

A recent report published by the British Royal United Services Institute (RUSI) estimated that due to the significant expansion of production, the Chinese People’s Liberation Army Air Force will field approximately 1,000 J-20s by 2030. Production is expected to be sustained at approximately 120 fighters per year. No other fighter type is being procured on even half this scale by any other service in the world, with these investments combined with the J-20’s world leading capabilities expected to expand the PLA Air Force’s already extreme advantages in its air-to-air combat capabilities. WS-15 engines are expected to fully replace WS-10C engines in production in 2026, and may have already done so

Apart from super cruise other things can be compromised on 5th gen. Super cruise is a part of stealth to reduce IR signature. I don't think IAF will also compromise on it.

Supercruise isn't an absolute must according to americans because the F35 can't do it either or they dropped the ball with it's design.
