Hi all,
I have read through some book and it said that in cold ambient condition [ISA -15C or less], the intake can suffer a supercritical condition and I did look up a picture of intake in supercritical condition and it show that the shock wave seems to get "sucked" in and the shockwave isn't concentrate at lip area. I don't understand that if the aircraft is travelling at M2.0 then the air passing through the engine should have the same mach no and hence the shockwave should be identical to the normal condition but it isn't. Can some explain this for me please.
Best regards
