Sr-71
Reading a book written by an SR-71 pilot and says "At Mach 3.2 cruise, over 80% of the thrust created comes from the inlet, 20% from the engine."
I realise at this speed the the engine is basically a ramjet and the flight manual quotes "At high altitude, military thrust is approx 28% of the maximum thrust available."
What I'd like is an explanation of (how? aerodynamics? mechanics of?) is the inlet providing 80% of the thrust.
Question for John Farley or those of his ilk?
