New MMPP Salyut AL-31FN ‘Series 3’ engines for China feature a 1T thrust increase as per contract stipulation:

Chinese press claims ‘consultancy’ may be sought for the J-20’s engines, and was the subject of a recent high-level delegation visit:

Me thinks they’re after the 15T AL-31F-M3.

I think there’s definitely sound reason & purpose behind the new camo scheme. It’s smudging and merging from light blue to dark grey is very careful, the effects of the dark grey tail fin’s borders is particularly illusory. Watching 55’s live stream when it banked (prior to landing) and revealed its top, my heart certainly missed a beat.

Palembang, did you paint that shark? If so I’m gonna recommended you for the PRC’s highest national bravery award!

That’s strange a google of msphere and kopp showed lots of hits..poor memory? or some may say telling fibs
here is the first on on the list

That’s an incredibly poor choice as an example. All MSphere is saying is that it’s pretty rich ActionJacksonMan championing Kopp’s Physical Optics analysis just because it concurs with his own DIY effort, whereas otherwise Kopp is the favourite whipping boy of the F-35 brigade.

Also, to coin your phrase “self-appointed expert” -AJM has yet to respond to the bombshell of frequency specific engine-duct backscatter and implications of [the same] frequency specific SWNT RAM (I know the latter represents a ‘World of hurt’ for him). He’ll have his work cut out though, in the face of overwhelming & insurmountable scientific/technical evidence from NATO, Japan, Russia, India, China and the US- as linked on the current PAK-FA thread (and strictly non- “counter-intel”).

Such silence from AJM strongly suggests his *analysis* are no more than heavily biased Personal Opinions (pun intended), so are we agreed that both he and Kopp have the same (highly dubious) level of credibility?

What is the fact that Kopp wrote a chapter in one of the classic textbooks on radar a “sure sign” of? That is not the sort of task one gets by being “a goofball”.

The fact that Kopp has oddball opinions on some subjects says nothing about his general reliability as a source, and the APA site remains a good reference point for anyone seeking unclassified data on (for example) Russian radar…

He also has good technical write-ups on US AESA radar developments over the last 2 decades, I believe that’s his field of academic expertise.

Found a lot of conflicting information……

No you didn’t. You found a seriously flawed/borderline contemptuous report on the PAK-FA (by that poor excuse for a journalist RFG) which you first posted on the ‘Chinese Air Power Thread’ and at least one other non-PAK-FA thread, then failing to incite a reaction there it finally arrived here. Now you’re peddling his very same report (the wording and glaring mistakes are the same), only using links from different country domains and declaring them as ‘valid multiple, open sources’. All this in the face of actual manufacturer links which you can neither open nor trust.

I could totally dissect the original RFJ report for you if you like, but it carries a risk that someone from IHS might read it and RFJ’s future commissions could vanish overnight. He is in the twilight of his career (mercifully), and I don’t want to see it end on a bum note. Also, your posts will be put in a very bad light indeed, proving that you’re incredibly stupid or a plain troll.

Either way, the vast majority of us moved on from ‘PAK-FA 101’ nearly four years ago, that you know next to nothing about that aircraft because you never bothered to read the news and posts here (despite time-out for your self imposed exile) is not our fault, is it?

…We wait

Komsomolsk-on-Amur has been badly hit by floods in recent weeks with water levels rising by up to 9 metres. Although the army was brought in to shore up levee defences and the KnAAPO plant was relatively unaffected, the workforce definitely would have been- and hence obviously disrupting day-to-day activity and schedules.

As the Indian’s are paying a huge sum they’re trying to use it as leverage to exact as much intellectual property from the Russians as they can. Unfortunately for them, there’s so many new technologies involved in the PAK-FA, with uses that extend way beyond it, that handing over IP (both academic and technological) is simply absurd.

We’re not talking about ‘Coca-Cola’s’ secret recipe here but the very technologies that the Russian government has invested in for over a decade to facilitate a rebalancing of the economy away from energy/raw materials’ extraction & exports. Also, involving the Indians in the ‘R&D’ @ this stage will simply delay the project they’d learn allot more if they requested consultancy on the AMCA, and could perhaps arrange a tie-in with the $5.5bn contract.

Such demands, as they stand, are unrealistic and unreasonable.

I thought this was quite interesting. Even with the T-50’s engine cowlings changing over to PMC (with CNT RAM), it still leaves a significant area of the nozzles exposed. However, a company called ‘GNIIHTEOC’ («ГНИИХТЭОС») has invented a ceramic composite specifically for rocket & missile nozzles and also ‘hot sections’ of future aircraft engines. It is due to enter mass production shortly and debut on the ‘Angara’ SLV:
