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

I think the relevance of information degrade with time as in this case.

The relevance is a personal thing, if you want to see no T-50 build in 2015, it will be irrelevant, if i want to see it as the press release is they will.

So there is no point to argue such point, the press releases say they will, if they do or do not become reality is something will we know later, but those are their plans, history will say later if they did or did not

I am simply saying that you can't have it both ways. If you are saying that the planned deliveries for 2015 is still valid, I am asking you whether you are prepared to accept that the prototype that caught fire had not been repaired as implicit in the same report?

The report is dated August 2014, now is February 2015, the Zvezda TV program was from December 27th 2014, the report does not say 055 will be not repaired, all are your opinions, you are entitled to them, i said Russia at least has 4 flying prototypes, one in hiatus, 055 is supposedly to be repaired, by 2015 they will have T-30 ready.

If you do not like that simply contact Sukhoi, tell them they are lying, 055 is totally destroyed, they will not built any T-50s and so and so, i am just telling you what they said, if you believe that or not is not my problem, i am neither trying to convince you or forcing you to agree, you are free to think whatever you want regarding PAKFA

Post a source or a link please, and it is totally different to have an ITR of 6.6 Gs from an airspeed of 1.6 mach, the Typhoon will NOT sustain 6 Gs at 50,000, here the Raptor will initially pull far more Gs bleeding off to a sustained rate of 6Gs at 50,000ft.
General Schwartz capped his statement by asking what other aircraft can do that?? the answer according to General Schwartz is NONE...

There are three sources. One is a pilot from early 2000s who said the Typhoon can do 5G mach 1.6 at 43000 feet. After a few years, the Typhoon's aerodynamics were further expanded and the airframe could handle more supersonic Gs. There was one official report which said the supersonic sustained Gs of the Typhoon was more than 7G, it could handle a 360 deg turn in 3000 m at mach 1.6. A different pilot said it was now 6G at mach 1.6 at 50000 feet. Both are youtube videos from a decade ago. There's no way I can look for those. Too bad they were not quoted in print.

The third source is an Air International article which said the Typhoon does greater than 6G at altitudes greater than 35000 feet, and that the F-22 is the only other aircraft to do the same. I don't have access to paid articles.

Americans are known to ignore West European capabilities. Although I'm pretty sure the F-22 will have a higher sustained turn than the Typhoon at that speed because the Typhoon was designed for ITR, not STR. Anyway in an interview with a female F-22 pilot, I remember reading her saying the F-22 does mach 1.6 6G at 60000 feet.

Reading between those statements, implicitly there is no new aircraft delivery expected in 2015.

Are you referring to production aircraft? That's scheduled for 2016.

Three prototypes are expected to join the fleet this year.

I think the relevance of information degrade with time as in this case.

In this case, it is as relevant as yesterday.

I am not convinced T-50 will be in service earlier than the Chinese J-20

Depends on the version of the T-50 and of course the timeline of the J-20's induction.

The definitive version will be ready only after 2020. The Stage-1 version will be ready for induction next year.

India, Russia sort out differences on fighter jet project

HAL’s share of work was a contentious issue in fifth generation fighter aircraft project
India and Russia have generally agreed upon the amount and division of work during the research and development (R&D) stage of the fifth generation fighter aircraft (FGFA) project.

A contract for the R&D phase is being prepared and expected to be signed this year, said Yuli Slyusar, president and chairman of Russia’s United Aircraft Corporation (UAC) at Aero India 2015 in Bengaluru.

“The Russian and Indian parties have generally agreed on the work share of each,” said company officials but refused to divulge specific details at this stage.

The work share of Hindustan Aeronautics Limited (HAL) has been a contentious issue as the project will have equal investment between India and Russia and is likely to cost over $30 billion for about 400 aircraft. India plans to induct 144 of them.

But HAL’s share in the work has been limited to a meagre 13 per cent so far which will not build any critical technological gains. Both sides have been holding discussions to sort this out before the final agreement.

FGFA is crucial for Indian Air Force’s evolving structure as was recently acknowledged by the air chief recently. The final announcement could come later this year with President Pranab Mukherjee visiting Moscow in June, and Prime Minister Narendra Modi expected to visit Russia twice.

The Izdeliye 30 engine for Russia’s T-50 fighter is undergoing rig testing, and will enter flight trials in 2017.

He (UAC boss) adds that the company has six T-50 test aircraft, two for ground tests and four for flight testing. Three additional aircraft will join the fleet in 2015.

“Everything is on track,” he says. “We are moving on as per the schedule agreed with our customers.”

Anyway in an interview with a female F-22 pilot, I remember reading her saying the F-22 does mach 1.6 6G at 60000 feet.

So the F-22 has far superior performance at altitude, and your little ITR vs STR is simply not true, in order to have superior STR at a given speed and altitude??? you must start out with a much higher ITR. Since the Typhoon is rated at 9gs positive, and the Raptor's G rating is classified, and it has TVC it is very safe to assume the Raptor is able to achieve a much faster pitch transition at 35,000 ft to 65,000 ft altitudes, where the Raptor lives, while the Eurofighter is very good at altitude, the TVC of the Raptor enhances greatly the initial turn in, that it will pull 6Gs sustained at 50,000 ft, tells you that without much better powerplants that the fifth gens in development will still fall short in the very high altitude performance arena of the Raptors excellent turn rates???
Your American's comment is number 1 not true, and number 2 is really another cheap shot??

Aircraft model photographed at Aero India would appear to be FGFA. If I'm not mistaken I see one seat in the cockpit.

Aero India 2015: New UAC chief bullish on fifth-gen fighter progress
James Hardy, Bangalore - IHS Jane's Defence Weekly
22 February 2015

New United Aircraft Corporation (UAC) CEO Yuri Slyusar is confident that Russia and India will sign a contract for the Fifth Generation Fighter Aircraft (FGFA) in 2015.

"Rosoboronexport [Russia's defence export body] is in the final stage of negotiations for the FGFA contract," Slyusar said on 19 February at Aero India 2015. "We think there is a possibility to sign the agreement within 2015. At least the Russian side thinks it will be done in 2015."

Slyusar, a deputy minister of Industry and Trade who replaced Mikhail Pogosian on 15 January, said that the two sides had signed preliminary and detailed design contracts for the FGFA programme, which is based on the Sukhoi T-50 PAK-FA fighter due to enter Russian Air Force service. "The level of co-operation we have with India [on this programme] is something we don't have with any other country," he added.

Pressed for details, he said that the workshare between the two countries on the FGFA was still the subject of negotiations, but "when we can tell you we will tell you" how the programme will be split between UAC and Hindustan Aeronautics Limited (HAL).

Indian officials have previously said that they are pushing Russia to restore Delhi's shared of the workload in the USD10.5 billion developmental programme after it was recently reduced from 25% to 13% without consultation. India is also seeking greater access to the fighter's design configuration, which it claims it is denied.

Enduring Indian reservations over the FGFA programme include questions about the fighter's AL-41F1 engine, although Slyusar said on 20 February that rig-testing for the next-generation Izdeliye 30 engine is under way.

The Indian Air Force (IAF) plans to acquire about 130 FGFA, down from an earlier projected requirement of around 220.

Meanwhile, UAC officials said the preliminary design for the HAL/UAC Medium Transport Aircraft had been completed and that the next step for the programme was to "define the technical performance characteristics". A Russian Air Force/IAF committee had been established to discuss this and after this was completed, the next step was to define the programme's "commercial parameters".

IHS Jane's reported in October 2012 that the two sides had signed a preliminary design phase (PDP) contract for the MTA, which is expected to have a payload of between 15 and 20 tonnes. Previously reported plans envisage 45 aircraft for the IAF, 100 for the Russian Air Force, and 60 for the international export market.

The Indian and Russian governments signed a collaborative agreement to develop the MTA in November 2007, with the joint venture between HAL and UAC being formed in 2010.
