Sukhoi PAK-FA / FGFA: Updates,News & Discussions

[Devianz]

Guys, any preliminary info on what they would eventually do about those exposed engines?

Radar blockers will be used, the after section will most probably be covered like in Su-34 and not exposed like in Su-27/30/35 once the final engine and flat nozzles are ready.

Well the PAK-FA is not going to be nearly as stealthy as the F-22 with estimated 0.5m2 RCS. Advanced AESA radar can probably detect it at around 70km. I guess that's why it is going to need super long range AA missiles against 3rd/4th gen fighters with AESA radars (F-16?). The downside is that the long range AA missiles have lower hit probabilities.

That's ridiculous. The Su-35 has RCS of around 1m^2, so a good estimate of the PAK FA RCS would be 0.1m^2 or less.

The 0.5m2 estimate was disclosed by a Indian military general if I recall correctly.

IIRC the figure was given by the Russians themselves. But they also quote RCS of the Raptor to be between 0.3-0.4 m^2. IMHO, the 0.5 figure stated doesn't prove anything they seem to calculate RCS differently than the west.

Yeah that's probably cause they look at all aspect RCS and don't consider just X-band RCS.

Third PAK-FA prototype breaks cover

Russian-language spotter pages are reporting the first sighting of the third Sukhoi PAK-FA prototype at the Siberian flight test centre in Komsomolsk-on-Amur. As soon as pictures become available, we will post them.

The T-50-3 prototype is reportedly scheduled for first flight by the end of 2011. It follows the maiden of sorties of T-50-2 in February and T-50-1 in January 2010.

The third prototype is understood to carry the PAK-FA's active electronically scanned array (AESA) radar. T-50-2 is an avionics and mission systems test aircraft, and T-50-1 is dedicated to flight sciences testing.

Sukhoi has already completed more than 100 flights of the PAK-FA prototypes in less than 22 months of flight testing, including a chequered appearance at Moscow's MAKS air show in August where T-50-2 had an engine blow-out on take-off.

At what nth protoype can we expect to see the PAK-FA with a stealthy engine and exhaust nozzle?

I think the PAK-FA has gone pretty well, its first flight was in beginning of 2010 and its 3rd prototype is just two years after that. I would expect it to go live in 2015 or 2016.

Depends on if Russia wants something like that. So far it seems they will take the Su 35BM engines and main avionics, to keep their timeline of 2015/16 for induction. The new AL 41 engine on the other side is just offered to India for a co-development (co-funding) and that engine might come with more features.
Btw, there are already more than 3 prototypes, but not all of them are for flight testing.

The third PAK FA prototype has joined the flight test program

Russian Aviaton » Tuesday November 22, 2011 16:18 MSK


The first flight of the third PAK FA prototype has been performed today at Komsomolsk-on-Amur Aircraft Production Association named after Y.A. Gagarin (KnAAPO), based in Komsomolsk-on-Amur , Sukhoi Company reports. AEX.ru

The jet was piloted by the honored test-pilot of Russian Federation, Hero of Russia, Sergey Bogdan. The fighter’s flight lasted more than one hour and then it has landed at the runway of enterprise’s airfield. The flight has been performed successfully in full accordance with flight assignment. The stability testing has been performed during the flight and the work of powerplant has been evaluated. The jet has performed well on all the stages of flight. The pilot has underlined the reliable work of all the systems and equipment.

The first flight of PAK FA has been performed on January 29th 2010 in Komsomolsk-on-Amur. The second prototype has performed its maiden flight in early March 2011. The work on ground and flight testing is in progress. The first public demonstration of the fighter has taken place in Zhukovsky on August 17th 2011 at MAKS-2011 airshow. More than 100 flights have already been performed in the network of flight test program.

PAK FA program assumes creation, serialization and passing into service the fifth-generation fighter. It will help increase the combat potential of Russian air forces; it will help aircraft industry and other related industries reach a new production and technical level and will give impulse to development of school of sciences, provide a stable workload for enterprises taking part in the development and production of the jet. This top-priority program of Sukhoi will contribute to development and implementation of new materials, element base and hi-end technologies with high innovative potential for aircraft industry and the country’s economy, for development of new projects of consistent next-generation aviation systems.

“As compared to the fighters of previous generations, PAK FA has some unique features combining functions of strike aircraft and fighter. Fifth-generation fighter is equipped with new avionics with an integrated function of “electronic pilot” and advanced radar with phased antenna array. It significantly decreases the load on the pilot allowing him to concentrate on performance of tactical objectives. The airborne equipment of the new aircraft enables real-time data exchange with ground systems and other aircraft. Implementation of composites and innovative technologies, aircraft aerodynamic configuration, visibility mitigation measures for the engine provide the outstanding low level of radar, optical and infra-red visibility. It increases the combat efficiency of the fighter in any weather and lighting conditions”, - the company noted.

First flight of Sukhoi T-50-3

Video showing first flight of the Sukhoi T-50-3 -- the third prototype to emerge under the PAK-FA programme. Note the absence of a pitot tube on the nose, a first in the PAK-FA programme so far.

@Spark:Bro is that the only change that is done to the third prototype?how about the engine blades any improvement on that?

Rumors of AESA in 3 rd P is there.

T-50-2 is an avionics and mission systems test aircraft, and T-50-1 is dedicated to flight sciences testing
