Abstract: Based on the investigation on the design of the variable geometry ventral inlets on the airplane EF2000 and F 16E,which are two different types of design,the successful and ripe design experiences of the proposed conformal Ⅲ B inlet configured on the F 16 multirole fighter are summarized and emphasised.It is found recently that with the forward movement of throat during the VGI diffuser ramp adjustment process,forward movement of the terminal shock is increased which is the main reason of the increasing instability of inlet operation at higher Mach number.It is desirable that the solving of instability problems in the similar variable ramp inlets may be benefit from the analysis.
