straight intakes are more efficient.
variable radar blockers may be used in place of s-ducts
>using the photo shopped picture
sneaky breaky vatnik
Most people claim it's shopped because you can clearly see much farther into the intake on the right side than you can on the left.
Still not as bad as vatniks that claim that the infamous picture that shows the fanblades is shopped and try to prove it by showing a completely different image of what it was supposedly taken from.
>what makes you think the pic is shopped?
Oh you snicky bicky Vladimir
Just increase the brightness, it's a shit photoshop comerade
no, you need to slow the airflow to subsonic to avoid compressor stall. but that is done on the intake ramp, way before the actual s-duct.
straight ducts are more efficient than s-ducts because it's easier to maintain laminar flow in them.
in the pak-fa picture, air flow is detached from the lower intake lip and a low-pressure zone is formed. this causes atmospheric water vapor to condense and form fog, which is clearly visible against the black paint on the lower half of the intake duct.

thats a real cool opinion, but you see it has a fuel line and a ladder extended, which means the engines are not on.
Because the fuel line would have a really good chance of getting sucked right into the intake.
Its a shoop. Either deal with it or be in denial.
It looks really strange, but it might not be a shop. If you fuck around with sharpness, brightness, and contrast, you can make out what might be condensation in the intake.
>why can't russia?
Can't? Nigga, even their old Yak-43 had S-ducts. They invented S-ducts!
>They invented S-ducts!
>Because their engines don't instantly die when a pebble goes through them.
the Soviet use this to maintain their airfield
they used it to defrost the airfield most of the time though

What a huge piece of shit.
Same thing with 4037, but at least that one had the decency to go down and not waste people's time.
maybe because carrier base aircraft need a shorter runway
>doesn't into supersonic flight
Doesn't matter. The S-duct on a fighter is behind the diffuser anyways (or sometimes, conveniently, part of it), so flow is subsonic in both cases.
All fighters and commercial/executive "jet" aircraft have turbo-fans these days, dude.
Fighters have a low bypass fan, and the others have a high bypass fan.
The military got away from turbo-jets a long time ago.
