No yet! Internal part of turbine's blades are closed by horizontal "S"

Re: PAK-FA Thread - First flight

Here are clearer pics from parlay. More than half of the engines are facing the intakes. Ofcourse this is only 2 dimensional, but when you super impose it with the bottom view, there is nothing much that can be done. But the theory of s ducts in above pic(the blue and red lines airflow pic) looks p...

Re: PAK-FA Thread - First flight

Really? Well lets hope so. I'd be nice if there is a pic. I don't care if Pak-FA is less maneuverable then F-22, or has lower thrust to weight ratio, or has a slightly higher wing loading. But I certainly hope that it's frontal RCS is better or equal to F-22(i.e only taking the design of both fight...

Re: PAK-FA Thread - First flight

Frontal stealth characteristics looks awesome, maybe even less than Raptor. But I really hope they have shielded the turbine blades from direct exposure... Those things are one of the biggest RCS contributors, maybe even THE biggest. The bottom needs a little work as well. I hope these things get s...

Re: PAK-FA Thread - First flight

^^ S shaped inlet is not such a super tech. Even F-16 has s-shaped air duct. Eurofighter has double s-shaped air ducts. So rest assured that s-shaped air duct is not such an exclusive tech that Russians cannot use it in pak-fa. Tejas also has y-shaped air duct. Yes! And Serbians wrote: Sorry, but w...

Re: PAK-FA Thread - First flight

Are you can't win on those machines? You made it in last war with Pakistan! You win at F-15, F16 and F-22 some years ago at India and at Nevada! Is it not enought? No No - I think you misunderstand. I was only pointing out that the Russian design bureaus have been producing original beauties for de...

Re: PAK-FA Thread - First flight

Well the funny thing is a long time ago my late cousin Wing Co Suresh was describing meeting a Russian designer from the Sukhoi bureau and said that when talk came to technology and transfer of technology he said "What is technology? I am technology", patting himself on the chest. I am re...
