RANGE EXTENSION OF ENGINE FLIGHT TEST BED WITH THROTTLE SCREEN

An approach to extending test range of the engine flight test bed by mounting a throttle screen before the tested engine is proposed.The relevant design principles of the throttle screen are given.The extended test limits by mounting a given throttle screen have been calculated.The rationality and feasibility of the approach have been proved by comparison of the calculated results with pressure loss data of an aircraft air-inlet screen.
