The Application of Pyrotechnic Shock in Korean Aerospace Program

한국 우주개발분야의 충격시험 적용사례

The tenn "Pyrotechnic Shock" or "Pyroshock" is used to describe short duration, high amplitude and high frequency transient structural responses in aerospace vehicle structures..The transients are generally initiated by firing of an ordnance item to separate or release a structural member of fastener. The objective of this paper is to present a set of pyrotechnic shock environment information - specific characteristics induced by many separation devices, prediction, testing, measurement and analysis methods of pyroshock environment. In addition, it is introduced the application of pyrotechnic shock test in Korean aerospace development program.
