Sukhoi PAK FA

And Indeed its Canards create additional radar-reflecting area. A LERX, while providing many of the benefits of canards (additional lift, additional maneuverability) are less observable in the radio spectrum.

Thanks for Information.

Good, as these are controlled by FBW system of the plane, it diversify manoeuvring and control, making it a sophisticated machine.

As in the quote above about radar reflection, Is it means FBW system or other systems be agitating the LEVCON to a specific position in a radar coverage theatres to provide more stealth or its just a physical add on for manoeuvring and control but compromising or enhancing stealth, is just coincidental or intentional ?

I know these are difficult question and only those who make or operate know it and may wouldn't like to tell us. Just asking for sake of asking and if lucky be able to get the answers .

It is impossible to answer that without conducting tests on the aircraft or Sukhoi officials themselves answer it.

Tikhomirov NIIP to Custom Build AESA Radar for IAF FGFA

Tikhomirov NIIP will custom build a AESA Radar for IAF's FGFA fleet, which will be different from the AESA radar that Tikhomirov is developing for the PAK- FA / T-50 fifth-generation fighter aircraft.

Tikhomirov-NIIP Director General Yury Bely revealed the information in an interview with Take Off magazine for its June 2012.

Tikhomirov-NIIP developed the Bars PESA radar that is currently fitted on IAF Su-30MKI fighters. The radar is supplied to the IAF BY Tikhomirov NIIP partner Ryazan State Instrument-making Enterprise. Ryazan is also helping HAL with local manufacture of the BARS PESA.

Under a preliminary agreement with HAL, Tikhomirov NIIP would also be developing the AESA radar for IAF's upgraded Su-30MKI aircraft. A final contract has, however, not been signed.

Meanwhile, Tikhomirov NIIP developed AESA radar for the T-50 has commenced flight testing on the T-50-3 prototype at Zhukovsky near Moscow in June 2012.

Test and alignment of the fourth radar is nearing completion prior to its shipping to Komsomolsk-on-Amur where the radar will be mounted on the T-50-4. Flight trials of the fourth AESA are expected to commence before the end of 2012.

Manufacture of two more AESA radars for subsequent PAK FA prototypes, is under way.

so the Russis will use the PAK FA t50 and we will use the FGFA?

same aircraft, different names, I still think that this should have no bearing on our own AMCA. WE should go ahead with the project whatever be the costs. Who's with me on this one?

The company "Dry" in 2013 will produce the fifth prototype fifth-generation fighter

Tests of promising Russian aviation complex tactical aviation (PAK FA) are in accordance with the schedule next year will begin service testing, said the president of the United Aircraft Corporation (UAC), Mikhail Pogosyan. According to him, is now in trials involving three cars. By the end of the year to connect the fourth test aircraft and, in 2013 - the fifth.
In 2013, the schedule will begin work with the Ministry of Defense Test PAK FA. In the implementation of the program to create a fighter is the problem: some systems suppliers rip time, there are issues of quality, in terms of performance. However, Pogosyan said, it is - working times that are inevitable when you create a fundamentally new technology, the 30-40th serial aircraft manufacturing process stabilizes. He noted that the Russian aircraft industry is extremely important to increase the volume of production, above all, civil and military transport aircraft.

Today, the aircraft "Sukhoi Superjet 100" is about 170 orders. Among the foreign customers - airlines in Indonesia and Mexico.

Indo-Russian 5th generation fighter now has Aesa radar : Sukhoi

August 8, 2012

The Russian aircraft manufacturer Sukhoi said Wednesday it has begun testing a fifth generation fighter T-50 (PAK-FA) with a single radar with active electronically scanning.

"In initial testing ground and airborne radar using an array antenna with phase control installed on a prototype T-50-3 gave strong performances in the plans" air-air "and" air-surface ". These performances are worthy of the best existing aircraft," Sukhoi said in a statement.

The T-50 must have all the performance of a 5th generation aircraft: a low radar signature and heat, a supersonic cruise speed, high integration of control systems, etc.. The aircraft is designed to replace the MIG-29 and Su-27 in service with the Russian army. The T-50 was developed in Russia since the 1990s.

From this pic it seems that PAK-FA is substantially longer than Mig29. As Mig29 is known to be 17.37m long, some simple interpolation calculation suggests that PAK-FA is about 22m long, about the same length as Su27. This is hardly surprising considering that both aircraft use same lines of engines. This should put to rest claims that PAK-FA is less than 20 m long.
