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

Those numbers are such baloney. Mach 2.1 supercruise? LOL nope. 2,000 km supersonic and 4,300 km subsonic range? Wow...

Former head of UAC (which owns Sukhoi) Mikhail Pogosyan stated that the subsonic range of the T-50 is around 3,500 km while supersonic range is more than 1,500 km. Those numbers are generously inflated, to say the least.

I giggled when I saw a member as recently as February this year claim that the T-50 will somehow carry four missiles per bay. Let me give you some facts. The following excerpt is pulled from Wikipedia, and its cited using quite reliable sources (Air International, AviationWeek, flateric and flanker from Secret Projects).

The T-50 has two tandem main internal weapon bays each approximately 4.6 m (15.1 ft) long and 1.0 m (3.3 ft) wide and two small triangular-section weapon bays that protrudes under the fuselage near the wing root.

is developing two ejection launchers for the main bays: the UVKU-50L for missiles weighing up to 300 kg (660 lb) and the UVKU-50U for ordinance weighing up to 700 kg (1,500 lb). The aircraft has an internally mounted 9A1-4071K (

) 30 mm cannon near the right LEVCON root.

There is at most room for three K-77M missiles in each bay, and currently, they only plan on having two of those missiles per bay. While the T-50 is capable of carrying a total of 4 Phoenix-size missiles (two per bay), in terms of quantity the air-to-air loadout of the T-50 will be no more than the F-22.

The T-50 will have little difference from the F-22 in terms of speed performance. The T-50 is limited to Mach 2 due to its materials, and I think the F-22 is also operationally limited at that speed. The T-50 does have greater range due to greater internal fuel capacity. It will also probably have the advantage in maneuverability in pitch and especially in yaw due to LEVCON and canted TVC, but rolling acceleration may be worse because of the bigger inertia from widely spaced engines.

Also, Air Force Brat, do you have the original source about the F-22's sustained g capability? I recall Schwarz saying that the F-22 can pull]/i] 6g at 50,000 ft, but I don't recall him saying that it will sustain it.

I believe General Schwartz, who is a C-130 pilot stated that it would "maintain 6 positive g's." He was preparing to retire and it may have been around some activities of the Air Force Association, just google the statement and I will do the same and report back to you!

You are correct, he does say pull, not maintain, so I am immediately issuing a corrective statement, I did get the exact wording wrong, and I very sincerely apologize, thank you for correcting my in-accurate statement, he was speaking at the Pentagon during a retirement press conference on 24 July 2012. I do believe that the F-22 will likely maintain 6 gs or near that at 50,000 ft, but I have no definitive proof to back up that statement.

It's not unreasonable to believe that the T-50 will "pull" 6gs at 50000 ft, but I am also certain that the F-22 will maintain a higher sustained g loading due to the F-22s much higher sustained thrust.

In today's AFM Daily Report, USAF projects the service life of the F-22 will have been extended to 2040 by some drastic cuts in actual aircraft hours and a further upgrade of flight simulators to provide a much higher percentage of training hours, "good move USAF!"
this will mitigate some of the concerns that these few airframes were being "used up" by lots of very high performance training flights, these exercises have been dialed back, and these beautiful, tactically critical aircraft will be babied in order to get their service life out to where we can reasonably expect the follow on sixth gens will be real operational airframes in USAF service.

March 23, AEX.RU - The deputy head of the Russian Defense Ministry Yuri Borisov on Monday confirmed plans to begin mass production of fifth generation fighter PAK FA (T-50) in 2016. So far, only one country in the world is armed with fifth-generation fighter - US aircraft F-22 and F-35. This was reported by RIA Novosti.

"We plan in the next year should be the first delivery of serial fifth generation fighter" - Borisov said during a visit to the Komsomolsk-on-Amur aircraft plant, where prototypes are going PAK FA for flight testing.

"The most important thing that we can say that the aircraft took place," - said the deputy minister. According to him, this year the plant will supply four prototypes for testing.

As reported, the use of PAK FA composite materials and innovative technologies, aerodynamic design aircraft, the characteristics of the engine provides unprecedented low level of radar, optical and infrared signature

seems T50-2 was damaged ,looks like cockpit canopy

a google translate of a russian comment in another forum

Cracks in the fixed part of the glazing. Which "increases". kosyachok sir, yes ... SchA will pick silicate technology lantern ... Something went wrong there. I wonder whether this is not the board, who went to high Mahi? if he did right then done that stopped him at M = 2.6 ... Overall, I think the project will not be affected. Well, maybe initially impose speed restrictions until sorted out with the technology.

Yes, and reportedly therefore the T50 was excluded from the parade in early April !

compare these 2 pictures around just behind the canopy area
@Deino what do you think is that goldenish quadilateral just behind the canopy

Yes, and reportedly therefore the T50 was excluded from the parade in early April !

the official reason seems to be

Fighter T-50 flew with a parade
Fifth-generation fighter T-50 flying over banned Moscow on May 9

Russian Defense Ministry has decided to exclude from the flight of the Victory Parade latest Russian aircraft - a fifth generation fighter T-50. Instead, it's flagship air the parade will be the Su-35 - the new Russian Air Force, outwardly indistinguishable from the Soviet Su-27. Experts believe that the decision was taken for security reasons, and note that the T-50 can be seen in August at an air show MAKS.

As told "Gazeta.ru" a source in the Defense Ministry, the decision to exclude the T-50 from Air Victory Parade program was dictated by safety requirements. "The plane had not yet passed the state test is not accepted by the Air Force, so there are no documents that would have given the right to include it in the flight program. Of course, this could be done by order of the Minister of Defense or the decree of the president, but no one took that responsibility, "- said the representative office.

On the question of why the tank "Armata", also did not pass state tests, given the opportunity to participate in the parade, the source "Gazety.Ru" replied that "tanks do not fly on people's heads."
