Abstract:

In the data processing of solid rocket engine testing system,zero point viaration is the main problem which has great influence on the precision of data processing results.Some phenomena of zero point viaration in thrust measurement system of solid rocket engine test were introducted.The basic principle of zero point viaration were analysed,and the data processing methods were also proposed.
