    When those pics of T 50 ( prototype 051) in its hangar were taken a press call was made to announce "greater involvement" of Russian Academy of Sciences' participation by raising the faculty from 1 ( on this date ) to 5 .

    This is *written* so poorly that I can't bear to finish reading it.

    Of course little tidbits of what may as well be complete BS, like the 20 year old APG-77 is "more advanced" than the NIIP AESA, caught my eye.

What's new is that they are now working on radar-absorbing composite fan blade for new jet engine to be mounted on the PAK-FA. This will eliminate the need for a radar blocker ( or a S-duct ).
    Not really, the blades will still have some reflection left.. and not to mention that there are still other parts of engine made of conductive metal that can be the source of RCS.

    Interesting... but that is where the main undercarriage is... there is no room for R-73s there.

    So the pakfa has 6 bays(4 in the middle and 1 at either side in the long slim protrusions beneath the wing). I find this a bit lacking though, only 6 targets could be engaged with missiles, perhaps the morphei could be small enough to fit 2 in a bay?

    It is the standard capacity for everything 5th gen, though some have increased since. The two main bays are clearly large enough to contain 6 missiles of R-77 size...will they in the future? We will see.

    NPO Saturn should ideally focus on fully developing the PAK FA's AL 41F engine . This development is going on for eternity & yet there is nothing concrete that has yet come out.

    Just look at how long NPO Saturn took to develop the AL-55I turbofan for the HJT-36 IJT & how long it is taking to develop a 20% uprated thrust AL-31FP .

    They need to swing for the fences coz as of now things are moving very slowly .

    Wasn't there a report recently about the engines going well and that they will be ready for the operational PAK FAs in 2016 or 2017 when they fully enter operational service?

    Most of the time the PAK FA will carry very light military payloads and with internal carriage there will be no external drag so the increased thrust engines are not really critical to its performance.

    I would say the new missiles being specifically developed for the aircraft will be much more important to how effective the aircraft will be.

    Lockheed has also produced tons of such reports for the last 5 years about the F 35 doing extremely well . Reports mean nothing .

    You kidding me ......right ? In that case why not have the engines of the SU 30 SM or SU 35S on the PAKFA ?

    The F-35 is a huge international program with lots and lots of customers that have sunk lots of cash into this aircraft... press releases have a different meaning for it.

    When Saturn starts lying then we can question the validity of its reports... so far its track record is good.

    You kidding me ......right ? In that case why not have the engines of the SU 30 SM or SU 35S on the PAKFA ?
    Actually the engines on the Su-30SM and Su-35S are from the current PAK FA... but funding has been allocated to produce more powerful and more fuel efficient engines so why would they not introduce that engine when it is ready for the aircraft it was made for?

    More importantly why introduce it now when it is not ready and risk losing an expensive prototype?

    thats the benefit of poded engine configuration in pak-fa unlike f-22 whose intakes and engines are of strict dimensions , the drawback is worse rcs ofcourse.

    I think that Su 35 has a 117S (AL-41F1S) similar but not the same than the 117 (Al-41F-1) of the Pak Fa, and SM has the al 31FP the same of the MKI (or maybe a 31MF1)

    Nothing wrong with PAK FA. The article is a joke seeing as they are taking some 'analyst' that somehow knows if they can mass produce new radar? And they state first one is hand assembled? They guys a tool. All brand new radars are hand assembled, and when the testing are finished, they move onto getting the facilities retooled to be able to run high volume production of said product. As well, they are claiming that they are using Indias contribution of FGFA for PAK FA development, when it has been known for quite sometime already that India has no contribution to PAK FA other than FgFA.

    Yeah, as well, introducing equipment for a 5th gen fighter, having to be 95% Russian components, is quite a feet, especially when development for such subsystems just started and are working out kinks before development.

    They dont list their sources nor do they remotely understand the difference between PAK FA and FGFA is the problem with that artical, which throws its credibility out the window.

    As well, you cant "hand make" composite materials. The way its dine on PAK FA like any other aircraft shows machenary has done it not hand. Or jet would look much like Irans so called fifth gen jet.

    Very much so. FGFA will help reduce cost of lets say radar, composite materials and engines over a long time for PAK FA, but not initially, and definately not now. As well, they wouldnt retool a facility to build radar that are still going through testing phase, I dont think any industry does that till the testing phase is done and they move onto full rate production. That is going to be some time. With Zhuk-A to end up on Ka-52k, radar components like the t/r modules will end up being cheaper over long term and thus reducing costs for the new aesa radar for pak fa.

    There are currently what? 4 pak fa's with only two of them with some avionics for testing purposes? They are jumping to conclusions far too early. Criticize in around 2017 if they still have not opened up a full rate production of the aesa radar and composite materials. But not now. They as well do not mention that composites have been in full rate production in Russia for a long time.

    That article is clearly written by someone with little actual knowledge of the program.
    Factual errors abound, regarding radar, engines...everything really.

    Pass.

    I need clarification on now the lower number of stages for new engine in hot and cold section will improve the performance ?

    The AESA description is very interesting. Any comments on the program's pace. Do you also think that PAK-FA will fall behind schedule?

    Thanks again Austin for the article.

    What is interesting for me is the misunderstanding of the financial aspect between India and Russia on FGFA. Since Indian Rupee dropped quite a bit, the price probably jumped high, and they are negotiating on lowering it? Well, they said it will be resolved by next year. But where is the 5 prototype indeed? Whats the hold up?

    As well, didnt know they are working on another radar for FGFA based on N-036. Interesting news.
