Saturn is the direct successor organisation to the Soviet-era Lyulka design bureau, Salyut is primarily a manufacturer and component supplier. For the role of project lead Saturn with its decades-long experience in designing complete engines (rather than just individual sections of them like Salyut, though they generally did a creditable job) is hard to argue against as a choice. The Izd. 30 was supposed to have Salyut input in certain areas like the nozzle, but the engine as test flown in T-50 #052 has Saturn-style ball joint TVC rather than the AVEN-type Salyut design, so it’s unclear whether that’s still the plan of record.

As for the AL-31FM3, it did look great on paper but I’m not sure whether Salyut was ever able to satisfactorily prove they could deliver on the promise in reality. Saturn had already designed and flown a 142kN derivative of the AL-31F on the Su-37 and with greater TBO becoming an important concern they were perhaps considered more likely to execute successfully. Again it’s hard to find fault with the decision, although I do hope the final Izd. 30 gets the Salyut TVC nozzle (the PYBBN/AVEN-design is just a more elegant solution IMHO).

With the Russian aerospace industry there is always the possibility of entrenched and rigid supplier-OEM relationships or politics too, though.

What’s the benefit of the Saturn nozzle? I also think PYBBN type nozzle is better solution since you get true axisymmetric TVC and you can create yaw without causing roll.

Talking about engines, is there reason why Sukhoi chose Saturn 117 instead of Salyut AL-31FM3? Apparently FM3 performed better than 117.

Also is it certain Saturn is making izd.30? Wonder why Salyut is being sidelined.

My only point is that side WB of the F-22 are huge to carry one single SRAAM and it is very hard to discuss this as a matter of fact, just look for pictures for yourself if you disagree. Making a 5G to carry air inside is not the best investment.

Let’s say similar. Su-57 appears to have bigger surface while F-22’s fuselage is more boxy and probably has bigger internal volume. Area ruling in Su-57 is very apparent, in F-22 it is not and that adds volume.
The same applies to F-35. Look at the picture you posted, the F-35’s fuselage is quite thick and boxy too, but it is not small and empty weight just confirms it. As said it is heavier than a 4G heavy fighter. It is compact around the CoG and that is probably very good to give authority to the control surfaces and get fast turning, but it is bad for aero, specially in supersonic flight. Cross-sectional area of the F-35 is between 8 and 8.5 sqm as said, F-35C maybe more, F-22 and Su-57 are both below 9.5 sqm. F-16 is <5 sqm. F-35 is hence quite close to being a heavy fighter in fact

Area rule is not about boxy, it’s about volume distribution. Note most of F-22’s wing and especially at wingtips is behind most of the fuselage and little is behind trailing edge, and most of weapon bay volume is in front of wing, while Su-57 main weapon bay go the entire length even at wingtips. So most of F-22 weapon bay volume is in front of wing volume while Su-57 weapon bay volume goes alongside wing volume. Either way to compare area rule you need full cross section area plot, it’s hard to eyeball.

He gets on the radio and tells an experienced, 3,000-hour pilot in a very capable fourth-generation aircraft. ‘Hey bud, you need to turn around. You’re about to die. There’s a threat off your nose.’”

The young pilot then “killed” the enemy aircraft and had three more kills in the hour-long mission.

“Even in this extremely challenging environment, the F-35 didn’t have many difficulties doing its job, that’s a testament to the pilot’s training and the capabilities of the jet.”

This is RuAF topic NOT F-35 topic. Your dick waving is adding nothing here.

Hate to break it to you. Yet, Turkey isn’t going to get the S-400 or become close friends with Russia but they will get the F-35. 😉

Why are you so excited about Turkey getting F-35? Especially considering even most US posters even on f-16.net don’t want Turkey to have it?

If Erdogan gets voted out it might change but until then S-400 is happening.

What money? India has contributed nothing to the Su-57.

It is funny to see people repeating long debunked nonsense from “anonymous Indian defense sources”, in other words, inventions of Indian (and other) media.

They have barely even had access to the plane aside from T-50-4 (or was it -5?) years ago.

This thread in general has long ago devolved to people who don’t actually read Russian sources parroting laughable sources like National Interest, or cherry picking the words of some Russian official to fit their narrative.
There is a reason nobody actually posts Su-57 info here anymore lol.

Where can people find actual news instead of constant bickering here? Since Berkut is gone things went downhill.

It’s funny that even on f-16.net no one takes his J-31 bullshit seriously.

@tr1

F-35 senior designer and head ceo of stealth uavs is robert ruszkowski. To me technically polaks are like russians. But its getting annoying having users come here and say my slav**** is better than your slav**** design on a su-57 thread.

What is this bullshit? This is as stupid as saying Japanese are like Koreans.
