摘要
Abstract
To predict the characteristics of subsonic flow field in front of aircraft inlet-engine combination in the free jet test of engine altitude simulation and to optimize the aerodynimic configuration of the test cell, the CFD method has been used to simulate the external flow of a fighter inlet in subsonic free-jet and in the real flight environment in the atmosphere. The relation of compression effect of the inlet to the inflow air and flight Mach number is analyzed. Optimized installation location of inlet has been found in three Mach num-ber of subsonic free-jet. And we compared the Mach number distribution of the forward and entrance of inlet between the condition that in free-jet and in real atmospheric environment. As a result,it can obtain the flow field of similar Mach number that the simulating of real atmospheric flight environment with subsonic free-jet.关键词
