I think with these smiles , the agresivity and flame on the forums will be reduced a bit :D……it would be a great idea..

Really i think these events are inevitable,russians constantly stress and test the US defences, so really these news arent the big deal…..until an accident happens

There is a lot of criticism inside and outside India about the tejas… but i think that a more powerful engine was inevitable, not because the tejas “overweight problems” -which i doubt, since i think this is a misinterpretation -, but because the kaveri was expected to have more power than the 404…

From where comes the overweight?

I wonder why the high percentage of Ti on the f-22?….is due the supercruiser requirement?, if is so, then more composites wont help, and knowing how conservatives and “tonka” thinking are the ruskis they wont use more than 15% of resine in their plane

Obviously they can drop the SC requirement -an idea that i support- and put more composites arround…but still due the composite plastic deformation, and knowing this is not an airliner -that dont must pull 9gs btw- …i think they wont pass over 20% of composites in such plane

Well, i think that industrialization of composites isnt a great challenge, compared with the manufacturing of the engine…also russians have a pretty nice experience with the berkut, which compared with the EF or even F-22, it composites aplication was far more complicated and challenging

And figure that…despite all these composite problems of the berkut -which , again the solution of these problems surely were a hell compared with the f-22-…that trash is still flying and doing his loops….., and i dont think that they had a great experience before that…so russians seems did it very well

Since ppl is talking about money, seems that the pak-fa is becoming in something more tangible…still we must wait and see..im still a bit skeptic

That remind me that the sukhoi guys really deserve the poject..they made a hard composite/unstable/forward wing/almost combat ready/heavy duty plane…at once, and did it well…and altought i hate the berkut…nobody can undestimate the Su guys

Centrifugal compressors reach a far better compression ratio than axial ones giving better thermodynamic efficiency, the problem is the exhaust velocity, axial sistems reach much better flow velocity, also packing centrifugal phases isnt easy task

Radial compresors could work nicely on subsonic engines, but i dont know about the supersonic performance

This thread remind me one i opened some time ago, anybody knows how many modern engines use radial phases?
