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

[Air Force Brat]

I don't know about the MKI, but the British claim the Typhoon can do 6.6G at mach 1.6 at an altitude of 50000 feet. No different from the American claim.

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...

Back on topic to the PAK-FA, that's the main reason the Russians maintain OVT on the T-50, to increase "sustained turn rate", no matter how much thrust you have, the aircraft will settle into a much lower turn rate than the initial turn rate. Both ITR and STR are equally instructive as the the actual turning performance of the aircraft, and those numbers taken together tell the whole story?

Please do post a link or a source to your assertions about the Typhoon???

Does anyone have any information on T-50 6.1?? has it completed its first flight? I would expect that any time?

If you read that article provided by aksha just above your post, it talks of continuation of test into 2015 presumably using existing prototypes. It then has a following statement that talks of delivery of a new aircraft in 2016 for operational evaluation. I am not sure whether this will be the T-50 6.1 but it sounds to me it will be a pre production version leading to LRIP. Reading between those statements, implicitly there is no new aircraft delivery expected in 2015.

something that will hopefully bring things back on track

Masalov also said that so far built 23 engine "article 117" - the so-called first-stage engines for the Russian fifth generation fighter T-50. With its tests should be no problem (according to plan, they should be completed in 2016), as part of its flow is identical to that of the engine at "117C product", which is equipped with Su-35 and who recently successfully completed the state tests, as in Wednesday signed the act. As for the engine of the "second stage" T-50 "article 30", then it should be 17-18% more efficient than the engine "117". At present the production of two prototypes gas generators "product 30", one of which will be harvested this year. In March, was completed engineering design stage of a new engine and clarified the requirements for fuel consumption and stealth, the first flight of the T-50 engines "article 30" is scheduled for 2017

The 117 is already in production, Masalov also said that at least upto December 2014, Russia had built 23 engines for PAKFA, thus at least two prototypes should pop up this year according to their plans

The following are relevant extracts from what you provided above.
"At present the production of two prototypes gas generators "product 30", one of which will be harvested this year. In March, was completed engineering design stage of a new engine and clarified the requirements for fuel consumption and stealth, the first flight of the T-50 engines "article 30" is scheduled for 2017"
The following is what I surmised from it :
1)23 engines built to-date
2)"Product 30" (presumably ehanced engine version). 2 engines in planned production in 2015 of which one is expected to be ready this year
3)The first flight with the enhanced engine (article 30) expected in 2017

There is nothing inherent in those statements to conclude " at least two prototypes should pop up this year according to their plans".

The Russian Air Force (VVS) will have received 55 Sukhoi PAK-FA (T-50) fighter aircraft by 2020, according to Vladislav Goncharenko, the deputy director of the United Aircraft Corporation's (UAC's) combat aircraft department.

The first PAK-FA deliveries are scheduled for 2016.

"The number of prototypes is increasing; the state trial programme is being conducted as per schedule," Goncharenko told Echo of Moscow Radio on 16 December.

Five PAK-FAs have been produced and three more are now being constructed at the Sukhoi Aviation Holding Company Y.A.Gagarin in Komsomolsk-on-Amur (KnAAZ).

Upon what it has been released, Russia has already started production of 117, they have 23 engines now, Sukhoi has 3 aircraft in the production lines, they plan 55 by 2020.

Engine type 30 will be built this year, it will start bench tests in 2016, by 2017 test flight on Pakfa, by 2020 ready.

It means by 2020 the later PAKFAs will have type 30

February 18, AEX.RU - Technical design of the engine of the second stage for the fifth-generation fighter T-50 made in 2015 will be made the first engine demonstrator. This was stated by Director General of Lenta.ru "United Engine Corporation" (UEC) Vladislav Masalov. "The technical design of the second stage engine for the PAK FA is made, and is currently being developed design documentation for the production of prototypes of the engine," said Masalov, noting that the work on the engine are conducted in full accordance with the schedule determined by state contract. Masalov reported that the first engine demonstrator of the second phase will be made in 2015. Earlier Masalov already said to the press that the first flight of the T-50 with the new engines will be held in 2017. At the moment, a fifth generation fighter T-50, produced by the Sukhoi Design Bureau for the PAK FA program, flies on the so-called "engines of the first stage of" AL-41F1 ("Article 117"). With mass production of their plan to be replaced by "engines of the second stage" (in the press, they were called "article 30"), which have improved characteristics. It was reported that these engines are superior to the AL-41F1 on the basic parameters of 15-25 percent and can provide supersonic cruising speed

If I understand these statements correctly, they are referring to engines and not the plane. Engines don't fly on their own. Back to the main point, there is nothing in the official statements that you had shared implicitly nor explicitly point to any new plane prototype deliveries scheduled in 2015. Please point to relevant statements to substantiate your point and not a bunch of statements that in my view have no relevance to the main point and I repeat "planned deliveries in 2015".

United Aircraft Corporation plans in 2015 to begin trials of two more units of fifth-generation fighter PAK FA (T-50), the head of the KLA Mikhail Pogosyan.

"To date, tests are held on four samples of T-50, next year, will connect the two," - said Mikhail Pogosyan reporters on Saturday in Komsomolsk-on-Amur in the celebrations to mark the 80th anniversary of Komsomolsk-on-Amur aircraft plant them. Yuri Gagarin (included in the company "Dry)

"We had planned in 2015 to complete the first stage of state tests fifth generation fighter T-50, and these plans are relevant. We are working hard to make this program was developed in the timeframe that we have stated. Today, in spite of the questions that always arise at various stages of testing, we are generally satisfied with the program, so plan to finish in 2015, the first stage of state tests and start from 2016 aircraft deliveries ", - said the head of the KLA.

Responding to a question about when to start testing the T-50 combat use, M.Pogosyan reported that this information for the benefit of the Defense Ministry were not disclosed.

The first flight of the PAK FA was held on 29 January 2010 in Komsomolsk-on-Amur.

Compared with the previous generation fighters PAK FA has several unique features, combining the functions of attack aircraft and fighter.

The use of composite materials and innovative technologies, aerodynamic design aircraft, measures to reduce the visibility of the engine provides unprecedented low level of radar, optical and infrared signature. This can significantly increase the combat effectiveness in the work of both air and ground targets at any time of day, and adverse weather conditions

The source of the news is Sukhoi, that is official

The source of the news is Sukhoi, that is official

This news article I believe is dated August 2014 and it even talks of just having four samples of T-50 being available for testing (presumably the one that caught fire had not been repaired). Are you saying that the timing for the two scheduled for deliveries remain valid in 2015 but the information on the one that caught fire is outdated? This article is at least 6 months old. There are no recent news that is collaborating with the information contained in this 6 month old article - not even the recent article shared by aksha.

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

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