Su-57 fifth-generation fighter may get flat nozzle for stealth purposes - pilot The flat nozzle technology is a breakthrough in modern aircraft-building, Major-General Vladimir Popov noted But now it seems there might be a way to bring the square flat nozzles back but maybe for later gen aircrafts since the Su-57 upgrades will only be the engines and sensor suite along with new weapons. They used square nozzles before on the Su-27 for reduced infrared signature, it killed the performance, so they used some kind of aerosol that helps reduce the engines infrared signature 3 to times less and went for the round serrated nozzle design. In regard to paintjobs, you chose a Su-57 without RAM for some reason than a Su-57 with RAM Trust me they have taken a lot of measures to reduce the RCS when they went with this design but we won't know if it offers more stealth or not while achieving high performance. Finally, it can apply the engine mesh screens to further reduce radar profile of the engine in case you need to, at cost of speed, and the second stage engine will have composite fan blades, and treatments to reduce RCS of the engine in the frontal aspect even without the mesh screens being engaged or without having S-ducts and fan blades are made of composite along with RAM coating. The engines also have a radar blocker in the intake to reduce RCS. The Su-57 uses a smoother partial S-duct, with less of a bend, it achieves some reduction of frontal engine profile, without killing performance too much, so it can go over Mach 2, and it can super cruise, even with the first stage engines. That and the fixed inlets are why certain aircrafts like the F-35 cannot super cruise and cannot reach Mach 2. In addition, because of all the gymnastics the air flow to the engine has to do with the S-duct, you get worse air flow to the engine, and even less performance. You are basically flying a brick at that point. A full S-duct was not chosen you get worse drag coefficient, and it kills the aircrafts top speed and acceleration. The air intakes are curved in the Su-57 and not straight. And of course since your a loyal follower your following very old information which has changed on the aircraft not really much of a surprise like the rest of your posts at this rate. I am starting to think that the user here might be the goofy blog user at this rate, probably explains why rockets were referenced for another aircrafts infrared detection than aircrafts themselves.į-18s use radar blockers but they are not the same patented design, they have straight ducts the Su-57 is curved. non-LPI/LPI radar is just cope when they have not stated what AESA modules are used or how they operate in public.IRST is small turns back when not in use with RAM and stealth material when not in use.The ducts are curved, use a patented design on shape with RAM and radar blockers.RAM is present everywhere even in the inlets.But I know that people with room temperature IQs do follow blog users like some religious figure and go fuck up their own reputation in the process so I will highlight the aircraft and changes of the aircraft that happened later since no-one follows the aircrafts program similar to why this thread was created posting old info like its new. We have similar requirements for visibility," Davydenko said. "The F-22 aircraft (the American fifth-generation fighter - IF-AVN) has 0.3-0.4 sq.m. Davidenko recalled that the fourth-generation aircraft - the Russian Su-27 or the American F-15 - have a reflected surface coefficient characterizing the radar visibility of the aircraft, within 12 square meters.
