Review of recent advances in pyroshock for space system

摘要：

　　Numerous pyrotechnic devices are used in aerospace vehicles to separate structural subsystems, deploy appendages, or activate on-board operational subsystems.The state-of-the-art for pyroshock prediction, design and test verification has not yet reached the maturity of other environmental disciplines, due to the complex, high-frequency nature of pyroshocks.However,recent advances in the analysis and simulation of pyroshocks have led to a better understanding of this environment.This paper presents an overview of the development of characterization of pyroshock, various experimental tests and simulations, analytical and numerical simulation for pyroshock prediction, and protecting techniques.
