Question

Engineers call the supersonic combustion in a scramjet
engine almost miraculous, “like lighting a match in a hurricane.”
Figure C9.8 is a crude idealization of the engine.
Air enters, burns fuel in the narrow section, then exits, all at supersonic speeds. There are no shock waves. Assume areas
of 1 m² at sections 1 and 4 and 0.2 m² at sections 2 and
3. Let the entrance conditions be M_a1 = 6, at 10,000 m
standard altitude. Assume isentropic fl ow from 1 to 2,
frictionless heat transfer from 2 to 3 with Q = 500 kJ/kg,
and isentropic fl ow from 3 to 4. Calculate the exit conditions
and the thrust produced.
