PAK FA performed the first docking with the tanker aircraft

Prototype promising Russian fighter T-50 (PAK FA) performed the first approach and docking with tankers Il-78 Russian Air Force, said in a press release, "dry". The trials involved the second prototype of the future fighter - T-50-2, as well as support aircraft Su-25UB with the crew of the Russian Air Force test center. Details of the tested were not disclosed.
Parallel as specify "dry", T-50-2 is being tested for stability, controllability and stability "in a range of subsonic and supersonic flight regimes in different configurations." The first prototype of the future fighter - T-50-1 - was trained to fly on large supercritical angles of attack, and tested for maneuverability.

In early August 2012 began testing the third prototype aircraft - the T-50-3 - a new airborne radar system with an active phased array and optical channels. According to the "dry", in the "air" and "air-to-surface" radar showed "significant and sustainable impact on the level of the best existing features of the aircraft."

Expected before the end of 2012 to the test program T-50 will join the fourth prototype. It was reported earlier that the test airframe PAK FA is to be completed in the current year and in 2013, the Russian Air Force plans to deliver ten aircraft for joint trials. Fighter series deliveries are scheduled for 2015. In total, the Russian Ministry of Defense until ordered 60 T-50.

Been thinking about what we can fit in the weapons bay of the aircraft.

This is the Mig-31s underside;


PAKFA's underside;


R-37 LRAAM, 38m diameter.

R-77 MRAAM, 0.2m diameter.

And this;
Mig-31 with 6 R-37s; 3+3. Plenty of space between the missile and the undercarriage. Seems to be similar in size to the PAKFA's weapons bays.


Even if we consider the PAKFA bays will carry 2+2 R-37s, 2 less than Mig-31, that would give space for 4+4 R-77s inside the bay. This is considering the weapons bays are smaller than the Mig-31s underside. So, it wouldn't be unrealistic to believe the bays will carry 8 R-77s.

The same Mig-31 version as the first pic. This time carrying 4 R-33s(0.38m diameter).

There is no way to know if the T50 PAKFA can match the F22 because so far only the basic air frame has been developed useing older engines. The best stealth the T50 can get and thats not likely, is stealth down to .01 meters compared to .0001 for the F22. The T50 is being designed to be a combination air superiority strike fighter more like the F35 then an air superiority fighter like the F22.....

The USA has developed a new air to air missile HPM generator for air to air missiles....http://defensetech.org/2011/09/22/air-force-successfully-fires-electromagnetic-weapon/ it should work well against planes and I understand the F22 is shielded, one of the more expensive parts of its production. The HPM range is classfied, it may be able down a flight of planes if they are close enough togather.....

Well Sukhoi sacrificed its all aspect stealth to gain super manuverability. and the .01 and the .0001 numbers are speculations. Yes the Raptor is more advanced in stealth design but being designed in the 80s it neglected the IRST and the EW advancements that took place after the 90s. This is the handicap of F 22 but albeit we need to wait for the final PAK-FA as the top speed of all these aircrafts are still kept classified.

And Russians also have their missile research going on the RVV-AD, R 74, K-100 and the R 37 are the Russian counterparts of the American programs.

Russia did not sacrifice anything. The flat nozzles have nothing to do with RCS, everything to do with supercruise. It is all design specific. But flat nozzles decrease IR footprint while sacrificing a little thrust. So, that's a good thing. F-22 has rear aspect stealth because they have placed radar blockers in the engines and ceramic matrix RAM on the nozzles.

PAKFA is an all aspect stealth design. It is claimed to not have sacrificed maneuverability to stealth, so advantage F-22, but the advantage is not very wide.

And Russians also have their missile research going on the RVV-AD, R 74, K-100 and the R 37 are the Russian counterparts of the American programs.
I don't know about the RVV-AD, but the export versions are RVV-SD(110Km), RVV-BD(200Km), RVV-MD(30-40Km WVR, maybe R-74) and K-100.

The Russians have their own non export developments which are slightly superior to the export versions.

Well I never told the rectangular nozzles were for stealth in the EM spectrum...but they are very good in the IR spectrum stealth. That is what I meant. The RVV-AD is more like the All Aspect American multirole missile that can engage both air and surface targets.

Hmm, Satish, I can't find any reference to RVV-AD. Is there a different nomenclature?

Some very interesting revelations here,
http://www.f-16.net/news_article4416.html

F-35 defeated in air combat simulation

An unnamed source stated that earlier this year a presentation was given by an industry air combat threat assessment expert to defense officials of a NATO country which showed that the F-35 Joint Strike Fighter (JSF) would not survive air combat against threats it is likely to see in its alleged service lifetime.

Part of the presentation showed a computer simulation which calculated that the F-35 would be consistently defeated by the Russian-made SU-35 fighter aircraft. The defeat calculated by the scenario also showed the loss of the F-35's supporting airborne-early warning and air-to-air refueling aircraft.
This is something APA analysts have been stating since a long time. If official simulations show the same result then that would be infuriating to F-35 clients who have to face advanced Flankers like the Chinese types.

APA did claim Su-35s can take out AWACS and tankers early on rendering F-35s inferior kinematics to the Flanker's domination.

Also,
he technology in the SU-35 will also see its way into growth upgrades of other SU-fighter variants used by countries like Indonesia, India, Malaysia and Vietnam. Chinese variants of these aircraft should also see similar growth capability in the coming years.
Obvious. MKI will infact be better when it comes to radar.

The Russian-made T-50, PAK-FA low-observable fighter now in development is expected to be much more lethal than the SU-35 in air-to-air combat against the U.S. made F-35. The SU-35 and T-50 made appearances this year at the Russian aerospace industry air show known as MAKS2011. Both aircraft will include sensors and networking which can minimise the effects of the limited low-observable qualities of the F-35. They will also have higher performance and carry more air-to-air weapons than an F-35.
More advantage to PAKFA, both against the F-35 and the export market.

There is more in the article.

The best I can tell learned from six generations of stealth operational planes the F22 does not need IRST at the present time because no enemy planes truly stealthy.. or I should say stealthier then the F22. The F22 stratgy is always going to detect the T50 or PAK FA first, its going to get its shot and then evade the the remaining T50 or PAK FAs. its impossilbe to defeat an enemy if you cant see him or find him.

What I find amazeing is the USA spends on Research, Development, Testing & Evaluation $79.1 billion
Military budget of the United States - Wikipedia, the free encyclopedia

This more then the entire budget of the Russian Military..74 billion....yet by some weird logic or miracle, or some weird thinking that defies all common sense you all think Russia is going to develope weapons equal or superior to the USA.

If I was you all I would really keep a close eye on the Russias that you are not buying a pig in a poke, I wonder if India could put togather a strictly objective committee that with out being bribed, or emotionally involved approve of the PAK FA. I expect Russia also knows they cant match the F22 and F35 or maybe even upgraded legacy fighters. But they got massive number of people to keep employed and India as a cash cow to keep them employed.

@p2prada :
Isn't 6 weeks for manufacturing a model for wind tunnel testing too much ?
Don't they use 3D Printers ? :confused:

The model isn't a toy. It is a scaled down version of the actual aircraft, at least the airframe aspects.

The wings and moving parts behave the same way as on a real aircraft.

This may be an internal record though.

3D printers? Models are made using metal or composites. 3D computational tools are used for measurement. I don't know what you mean by a printer.
