Abstract:
Thrust is one of the key parameters of the rocket engine performance. The accuracy of thrust measurement in liquid rocket engine testing is important to the impulse and the engine performance evaluation. Negative thrust is one of the important factors influencing the accuracy of thrust measurement in liquid rocket engine testing. The reason of negative thrust generation, negative thrust correction technique and the thrust measurement in the liquid rocket engine testing is described in this paper.
