An Experimental Study on Thrust measurement Method of Supersonic Wind Tunnel from Pressure Measurement

압력 측정을 이용한 초음속 풍동의 추력 측정 방법에 대한 실험적 연구

The determination of thrust is very important in hypersonic air-breathing propulsion design and evaluation. Because of the short flow-residence time in the combustor, the evaluation of engine performance is strongly influenced upon the engine thrust. Conventional methods to determine the thrust is using thrust stand or force measurement system. However, these methods cannot be applied to the case where thrust stands are impractical, such as free jet testing of engines, and model combustor. With this reason, the thrust determination method from measured pilot pressure is considered and evaluated.
