PRELIMINARY RESEARCH ON WAVE AND FREQUENCY SPECTRUM ANALYSIS OF DYNAMIC PERFORMANCE PARAMETERS FOR EJECTION POWER

The purpose of this study was to investigate the transfer function of ejection power of pilot escape system. The simulation tests were conducted by using linear mechanical vibration system and the data measured were processed by the method of wave and frequency spectrum analysis of digita signal. A preliminary analysis of the processed test data is briefly described in this paper. It shows that processed results of test data are in compliance with the feature of ejection power performance and dummy model. The computational equations and method selected are reasonable and practicable.
