ABSTRACT:
To promote fuel and air mixing combustor of a scramjet engine, fuel is injected as a succession of pulses into the airstream flowing through the combustor. By controlling the duty cycle and flow rate of the fuel pulses, increased fuel penetration and mixing efficiency are obtained with an overall fuel flow schedule comparable to steady state fuel injection. With sequential pulsed operation of plural, variously located fuel injectors in phased relation, the combustor remains in a transient state to enhance mixing and to spread out the combustor heat load.
