F-22s doing the ‘Mach Loop’, NW England:
T-ViP, UMPO’s 2013 yearly report confirmed a contract with OKB Sukhoi to supply 12 117 engines specifically for “Stage 2 PAK-FA prototypes”.
T-10KM-2.
Well, at least they’re building them in an impressive, brand new assembly hall now – as opposed to the rather dilapidated cowshed for the very first examples.

I know the gear was down, but notice how the F2 effortlessly keeps up on dry power.
Nonetheless, a considerable indigenous achievement and moment of pride.
Probably T-50-6-2 @ 0:30 – 0:32s:
The INR has appreciated 11% vs the EUR since PM Modi signed the agreement in Paris last spring. The trend is for further appreciation so I guess it’s in Indian interests to delay a little longer.
Doesn’t mean to say the Rafale will be a *bargain* by any measure – pricing in all factors it’ll still weigh in at an eye-popping >US$244m per unit. Must be the only plane in history to defy economies of scale.
In the face of attractive ‘Make in India’ offers from Boeing, Airbus, SAAB and others, I can only assume it’s acquisition is to keep the French government happy for the EDF deal.
Signor Martinez, you may be onto something! The brown is most certainly polymer matrix composite, the yellow is Ti and Ti-Al alloy and the bluey-grey is (I would hazard a guess), carbon-fibre reinforced metal matrix composite – as it’s too shiny to be Al-Li:

Yeah, the AL-31FN is actually longer than the ’31F – despite having a shorter nozzle:

…What is that I spy behind the LEVCON? 🙂
Why, doorless conformal SRAAM bay, of course!
Something else that’s quite interesting. The missing engine nozzle reveals an acute triangular vent – a feature not seen on any FLANKER derivative at the same location.
I wonder if this has anything to do with thermal signature management, note how a gap is left between the nozzle:

The development contract for the AL-31FN was signed between Chengdu and NPO Saturn on 31st March 1992.
Later that year 10 serial AL-31F engines were delivered to MMPP Salyut’s facility to be modified to AL-31FN standard, 9 of these subsequently went to Chengdu’s facilities.
So, yes the AL-31F can be modified to FN standard, but would it be economically viable? Especially given that the latest AL-31FN Series 3 for the J-10 will be even further removed from the baseline ’31F.
Here the joint Russo-Chinese design staff are pictured in front of the first AL-31FN:
Well given that:
Oh, if anything i am always the most pedantic one. 😀
why don’t you ask him whether they’re 117 and ground vibration tests to verify the T-50-6-2 FC & management system (KSU’s) and its responses to inputs to the LEVCONS, wings, tails (horizontal & vertical stabilisers, ailerons, LE & TE flaps etc)?
Which, incidentally, would be common procedure especially given that it’s a new ‘Stage 2’ development prototype being prepped for its first flight – and he’s already stated it’s “a new version” of the KSU.
…….or is it what you wrote?
…частотные испытания с новой версией КСУ,
Means (ground) vibration tests for the new integrated digital control/management system (КСУ/KSU), scheduled completion today. This is very much an avionics hardware system, f.e. here are the KSUs for the 29KUB and Su-35S:
