In the first video at 1:27 and 1:29...whatever the plane is dropping hits the underside and the engine nozzle...Specially at 1:29 we can see the dropped bombs or whatever they be,interfering with the engine exhaust after hitting the engine itself...
Huh! Where did you come to that conclusion? I saw your one more post claiming the same. What's with you and Su-34?
PAK-FA is a 5th generation stealth fighter in prototype stage for now, mean for performing both air superiority as well as ground strike roles. It is supposed to have supercruise, very low radar cross section, supercruise, AESA radar, 100% FBW system, 3D thrust vectoring etc.
A ground strike fighter-bomber, meant for carrying A2G weapons- a bomb truck in short.
Where do you see similarities in them, either in paper or in reality?
