The paper presents the shocks arrangement of ramp compression hypersonic inlet with fixed geometry within a range of flight Mach number.The effect of internal contraction ratio was studied based on the inlet optimization design with the objective of scramjet thrust.The design methods for the inlet shocks and bleeding slots were then developed.The result reveals that an optimal inlet internal contraction ratio exists for on-design engine thrust,while the pressure ratio and mass flow capture on off-design con...
