Abstract:
The method of slow strain testing for the liquid-propellant rocket engine is introduced in the paper. In order to research the centroid shift of the liquid-propellant rocket engine, the detecting points are reasonably collocated on the force transmission constructional elements to detect the slow strain parameters of the engine frame, pressure lever between thrust chamber and engine frame, and front-end of thrust chamber. The preliminary judgement for the centroid shift of the liquid-propellant rocket engine was achieved after the processing and analysis of the detected data.
