Russian Su-57 Aircraft Thread (PAK-FA and IAF FGFA)

it is obvious Sukhoi based the T-50 upon the YF-23, they are different aircraft but definitively they based the PAKFA more on YF-23 than F-22
Oh yes...most of us have recognized that from the start. Not as stealthy as the YF-23...or as exotic...but they are producing a very good aircraft, and with a lot of their own innovations built in.

Now they just need the money to build them.

Man!.. Why you wanna make me defend the Russians! Ok maybe loosely is more appropriate but to be fair I don't think the Russians copied much at all from the 23.
It has 'some' design features of the yf23 but the inclusion of levcon, swept angles of the control surfaces etc tells me the kinematics are quite different. Not saying it is more or less maneuverable but one thing I can almost bet on based on my experience is pakfa will most definitely have an agility advantage in the higher Mach regime.
Russians know how to built planes. They just have problems with $$ but never lack of knowledge or expertise. People in the industry will honestly tell you that their aeronautical engineers and scientists are just as smart and capable as anyone working at Lockheed or Boeing.

Tests completed for the equipment and means of rescue of pilots on T-50:

Zvezda NPP experts finished testing the unified protective helmet ZS-10, new generation oxygen mask KM-36M, G-suit PPK-7, pressure suit WCC-17 and oxygen system COP-50 . Last year, the state tests were completed wrt ejection seat K-36D-5 .

They do stay a step ahead with their surface to air missiles, don't they?

They are much more serious about their surface to air missiles simply because we have the capability to penetrate their airspace, and have done it before to "verify" what their capabilities actually are? Anecdotally more than 4000 missiles were fired at the SR-71s, sadly the grand old "Blackbird" isn't with us any longer?? but we still have the means to go "downtown" with a package, if not the desire?

All of the measures we have taken for "arms reduction" have no doubt hurt our capabilities far more than theirs, but we still have the means to do what needs to be done.

This is one of those few airplanes that actually look better sitting on the ground than in the air, she has that "cover girl" look??? aesthetics aside, this is a very pretty airplane, but I would say that some of the initial cracking in the aft fuse is likely due to the aft weapons bay, which has introduced a large cavity in an area that is on most aircraft very heavily structured. I also note that there are several hard points attached to the wings, but not to many.

This is an aircraft that is still very conventional, no doubt an upgrade from the Flanker, but still not the true fifth gen that the F-22 is, and I'm not trying to be "snarky" here, but honest? This is a very awesome aircraft, it likely would be equal, possibly even superior in the fur-ball to the F-22 or F-35, it is all wing and tail, lots of lift, no doubt will pull a lot of Gs, but some of her issues have really slowed down her development process?

Back to aesthetics I will note the the J-31 looks very similar to the T-50 picture in the lower photo, even though the J-31 is much smaller and may in fact be stealthier, particularly in FC-31 form?

Come on are you serious?

i will mention a few facts to prove how wrong you are:

A) T-50 has F-22 type intakes, diamond shaped and not F-15 or Su-27 like wedges

B)T-50 has semi ventral intakes, not ventral not lateral, it has intakes in the same position to Rafale since part of the inner lateral wall of the intake is attached to the lateral fuselage side, Su-27 has a pure ventral intake, the lateral walls never touch the fuselage and is the upper horizontal wall that is attached to the Fuselage and where the boundary layer splitter and gap separates the intake from the fuselage.

C)T-50 has LEVCONs and not LERX and the leading edges are aligned with most wings and intakes and tail, Flanker has not such features.

D)T-50 has an all moving vertical tail, its position is like F-14 but it works like the one of SR-71 and YF-23, not similar to Su-27

E) T-50 has different wing leading edge angle of sweep due to super cruise needs, a feature not seen in Su-27

T-50 has 30% composites and 70% of them on the fuselage.

T-50 has smart skin, it means it has smart RAM, by the use of 5 passive and active radars .

common features with Su-27 are fuselage-wing blending and widely separated podded engines, these are also common features with YF-23.

Its weapons bays are also like YF-23, this reduces the frontal fuselage area making for a small nose like YF-23.

Main critics claim the engine nacelles are like Su-27, and are not as stealthy like flat bellies of F-22, this is very subjective since flat surfaces concentrate the radar signature in one direction, while tubular ones are omni directional but reflect weaker signature peaks and treated with RAM and composites and attaching a booms reduce greatly the radar signature of the nacelles and reduce the air drag .

I'm very serious Bubba, and I'm the one who told you 055s fuse was toast and that Sukhoi would pull a fuse off the line and plug and play 055s wings, tailfeathers, and thangs. (which is what they are doing by the way, should fly soon? I hope, I hope!) So while you make some awesome observations, this is a very kooool airplane, I am the pilot and airframer here on SDF, and when I am wrong, I issue very upfront, public, and heartfelt apologies, but, I do really enjoy "boxing your ears" once in a while, cause you are still a pup. The "Old Dog" has to have a little fun keeping you young-un in line.

So just for instance your "LEVCONS", that you love so much, really LockMart is not losing sleep thinking, man I sure wish we could put LEVCONs on the F-22, F-35, sixth gen proto-type???? whatever???
While they are kool, they kinda add some mojo to the T-50, I ain't that impressed! Something else to break? have to tweak? try to keep it all doing what its supposed too???? and working with the rest of your FCS??

I love ya man, I do consider you my Bubba, but you are my little Bubba, you oughta show a little more respect to your elders, or you will grow up with funny lookin ears??? no disrespect, but you've gotta earn your place, and you gotta know your place, I listen to everybody, and I learn a lot everyday.
I know who the Big Dogs are, and I don't pull their ears???

oh, and as far as "proving me wrong??" whats that all about, I am well aware to the T-50, its a great airplane, but if I were in a Raptor, and you were in a Sukhoi,,, well lets just say I'd send ya some flowers?? LOL, earnestly and respectfully your Bubba, the AFB, but I do love the PAK-FA, I do, and I am impressed, wish I had one to "play with"!

you are wrong and i mean no disrespect.

T-50 has several features common with YF-23 rather with Su-27, T-50 flew 20 years after YF-22 and YF-23, you can see the advances simply in aerodynamics, the LEVCON is one, and that is a visible one.

I will not tell you which one is better, since that is a futile work, i will simply say the T-50 has different philosophy, it is designed to track stealth aircraft by means of 5 radars and an IRST system; escape enemy missiles by means of super cruise, and a variable geometry intake that will allow speeds of Mach 2.5 at max speeds and 1.8-19 Mach supercruise.

It is designed to be as stealthy as F-22 by means of planform alignment, composites and a smart skin.

In few words it was designed to be faster, and more maneuverable with a blend of Passive and active radars to detect its rivals at theoretically longer ranges, if it really does or does not well History will tell, but the philosophy of the T-50 reflects two main trends, stealth aircraft can be detected and speed is life and if you can not out run it you have to dodge it
