Abstract

Aiming at the problem of fault prediction of a rocket ejection seat in a fighter, based on the analysis on the stochastic fault mode and wear fault mode, a fault prediction method for the rocket ejection seat is proposed. First, the main two failure modes of a rocket ejection seat, including the stochastic fault mode and wear fault mode, are analyzed, then the prediction method for the stochastic fault mode based on the life distribution of the fault mode is established, then the prediction method for the wear fault mode is established by determining the fault sensitive parameters which reflect the performance degradation law of the rocket ejection seat and calculating the occurrence time of the fault according to the given specified value. The methods are applied in the fault prediction for a rocket ejection seat, and the result shows the predictive results are consistent with the engineering practice. The effectiveness and feasibility of the method is validated in this paper.
