From what I read, the air in a scram-jet is not slowed down to be below the speed of sound. I expect the combustion velocity must be greater than the speed of the air, otherwise the engine would keep flaming out, and would need to be constantly ignited. Three questions: 1) Can the combustion velocity actually be greater than the speed of sound? (I expect the answer is NO). 2) What is the limiting velocity for kerosene-air and for LH2-air in an engine? 3) What is the limiting combustion velocity for kerosene-air and LH2-air?

How do you compute the combustion velocity, or is it purely empirical?
