Russian Su-57 Aircraft Thread (PAK-FA and IAF FGFA)

Finally the engines are covered, I never really figured out why they were not in the first place.

They have always been covered, but those cowlings have now been painted in camo, rather than the flat black that that doesn't show normal wear and heat. Just the aft station remains flat black. When you are cowling and uncowling engines, those covers get dinged up and kool paint gets chipped and heat faded, showing wear. The flat black is just a more practical coating while you are doing lots of buttoning and unbuttoning.

A few changes, more likely the internal structural enhancements are the real story, and we should hear bits and pieces of that coming out soon.

thanks for the explanation, however new question arises, is this a Sukhoi specific practice? All the current Su-27 families feature this not-painting operational including the Chinese variants. All other Soviet/Russian planes do not paint.

those are telemetry aim points for the cameras to get an accurate pitch rate picture of what the airplane is doing at various angle of attack, calibrated airspeeds. Much like the notation I made that the F-35 was carrying more alpha than the F-16s on that thread.

Are those telemetry aim points? I'll give a comparison. To me they look like radiation warnings. Other Russian aircraft also have them:

PAK-FA T-50 (055 and 056)


Compared to:

NLCA, J-10B, J-15, F-35 test markings

That's not a "nuke boat" Bubba, those are what they are, the triangles establish "Planes" and angles on the planes, lines of symmetry, this baby is in test flight as the first -2 bird, she is a flight test bird, she will hit all the high points and push the wussy places where the -1s where weak and cracked. She is likely a little overbuilt, every "clean sheet" aircraft is a whole new chapter in the book!

But, I will remind every one of the AFB's almost favorite saying? "A Flanker, is a Flanker, is a Flanker", in this beautiful bird, the heart and soul of the lovely, giving, anxious Flanker beats just as surely as a nuclear powerplant!
