Sukhoi PAK FA

[p2prada]

AMCA's feasibility study started at around this time last year. It was supposed to go on for 18 months. Do you have any source saying that its design phase has already started.

No. Feasibility study was completed in March this year, or was it April. One of those. Rs 100 Crores was released in mid or end 2010 for the feasibility studies. So, that finished the 18 month cycle a long time ago.

ASR was created more than 2 years ago. Preliminary design phase started in July-August of this year. The prelim design cycle is so small because ADA has been working on AMCA for over half a decade now along with the requirement changes in 2009.

Seems to be a Rafale class aircraft. The last we heard it is to be a 16-18 tons aircraft with 2 tons internal payload and 4 tons fuel. So, expect it to be a medium weight fighter weighing 9-10 tons when empty. Rafale weighs 9.5 tons and carries 4.5 tons of fuel. Add 2 tons of payload and it is a 16 ton aircraft. Similarly EF weighs 11.5 tons, ~5 tons of fuel, add two tons of payload and you get ~18.5 tons. So, you get an idea about where AMCA is. 2x90KN engine and we get a T/W of much greater than 1 when the aircraft is carrying full fuel and 2 1000Kg bombs or even better when it will carry at least 6 Astras and R-73s.

You can say the basic specs are way better than what's on Rafale or equivalent to a Rafale with 90KN engines instead of the current 75KN engines. Maybe an initial engine growth to 100KN to cater for weight increases and avoid problems later on. If weight specs stay the same we may see flight performance below FGFA and above current gen F-22 with T/W greater than 1.2 when fully loaded. This is speculation, but the current specs gives off such an image.

The final design will be shown to IAF by this year end. Once IAF decides whether it is good enough or needs more modifications, the final design phase will start, hopefully early next year. So, at best the design will be frozen by mid-end 2014 followed by the 3-4 year prototype build cycle until first flight.

After that cross your finger and hope to die that the aircraft is not another white elephant.

In August 2006, India's then defence minister Pranab Mukherjee announced in Parliament that the government is evaluating experiences gained from the Tejas programme for the MCA.[2]
In October 2008, the Indian Air Force asked the Aeronautical Development Agency (ADA) to prepare a detailed project report on the development of a Medium Combat Aircraft (MCA) incorporating stealth features.[3]
In February 2009, ADA director P.S Subramanyam said at a Aero-India 2009 seminar, that they are working closely with Indian Air Force to develop a Medium Combat Aircraft. He added that according to the specification provided by the Indian Air Force, it would likely be a twenty ton aircraft powered by two GTX Kaveri engines.[4]
In April 2010, the Indian Air Force issued the Air Staff requirements (ASR) for the AMCA which placed the aircraft in the twenty five ton category.[5]



By August 2011, the aircraft was in its preliminary design phase. As of July 2012, with aerodynamic design optimisation near complete, the AMCA's broad specifications are final. The aicraft will have a weight of 16-18 tonnes [16-18 tons with 2-tons of internal weapons and four-tonnes of internal fuel with a combat ceiling of 15-km, max speed of 1.8-Mach at 11-km.[9] The final design is expected to be shown to the air force by 2012, after which full scale development on the aircraft may start.[11]

the 16 to 18 ton empty weight ASR was released on 2011 august, That is what we all heard at last,not three years before.

In November, 2010, The Aeronautical Development Agency (ADA) had sought $2-billion (approximately 9,060 crore) fund for the development of the advanced medium combat aircraft (AMCA).[12]
PS Subramanyam subsequently stated, "We have just started working on this fifth-generation aircraft, for which we had already received sanctions to the tune of Rs 100 crore. The way the government is cooperating, I am able to say that we will receive the funding ($2 billion) in the next 18 months."[12]
Funding will initially be utilized to develop two technology demonstrators and seven prototypes. The first flight test is expected to take place by 2017.[12]

Only 100 cr funding has been released till now.
If achievable targets with well thought out one time only final ASrs are given, there will be no white elephants

Broadsword: Delays, challenges for Indo-Russian fighter

The HAl says FGFA which is far more complex than LCA will need 15 years of test flight according to this report.

 

[p2prada]

Read again. It will take 15 years without Russian help. With Russian help, it won't take 15 years.

If no x band radar BVR lock can be obtained on the 5th gens,then what is the point of having superior tech in avionics?
Ultimately it seems however advanced your avionics ,you cannot get a lock on the enemy 5th gen.
What is your thoughts on this.
Then only dog fights are possible it seems.
Even for that ,a defending 5th gen has to find enemy 5th gen while wandering at random,Is it real?
Then don't you see russian adherence to superior kinematics and dogfighting skills coming to the centerstage again?

There is no doubt with the speed electronics and warfare is advancing that missiles will be able to lock on to 5th generations planes and be more deadly and more effective. I am almost positive that USA has EMP missiles that will destroy an enemys plane electronics just be being in the area of an enemy plane and I am certain that Russia and China are not far behind. The same for ground based missiles. They are going to be more effective at longer and longer ranges. That being said, the more stealty plane is always going to be less vuneralbe then a less stealhy plane.

Defence News - DRDO To Complete Feasibility Study For Indian Stealth Fighter Project

The above report was posted during march 2011. Which means that feasibility study should have been completed just about now, provided that there were no delays. Also, there is no source saying that design phase has started.

 

[p2prada]

There was a release from NAL on one of the wind tunnel configurations.
http://www.nal.res.in/pdf/ch1dir.pdf

Unofficial work has already started. Like I said, they have been working towards it since half a decade now.

active defence: Update : HAL AMCA - Advanced Medium Combat Aircraft

Also, from an Aviation week article,
Aerospace Diary: India Develops Requirements For Advanced Medium Combat Aircraft

The Defense Research & Development Organization (DRDO) had announced earlier this year that the AMCA program would be launched in 2010. While unofficially work has started on the design, according to an official, the AMCA will be officially announced in 6-8 months. "There is nothing official about it "¦ It is currently not a sanctioned project from the government. We are looking at the technical requirements submitted by the Indian air force," the official told Aerospace DAILY.

Obviously ADA has been working on AMCA since 2010, without official govt sanction.

Apart from that both ADA and GTRE have asked the govt to sanction $2Billion each.

 

[ersakthivel]

they were working on non vertical fin strike type fighter from 2005 and that was dropped and ADA chief himself has said that the work done can be utilized in only tejas mk-3.
The previous raptor like figure was shown in aeroindia last time which pertains to 20 or 25 ton which is not clear.So all the work done on it cannot be automatically applied to 16 to 18 ton present ASR which was given only on 2011 august.So actual configuration of the aircraft for the last ASR should have started just a year ago.
And lets hope the asr remains the final asr.

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.

nice adoption of existing flanker airframe with minimum fuss.Hope the engine turns out better.
What is the RCS figure?

 

[ersakthivel]

Makes for a nice wallpaper,but sadly not the PAKFA design.

Was it a concept or artistic work?

Expected one of this.

Expecting similar ones, especially for J-31, maybe by next year end because photos need to become available.

I am wondering are they making any progress on this bird or not ...:shocked: because I am not seeing any progress in the air frame means the internal weapon bay.

Weapons tests are set to happen in 2013.

Recently it has all been about opening up the flight envelope.
