초록

In this paper, we have proposed a separable nose cap and its opening device to protect a seeker's window from aerodynamic heating and to decrease the drag force on missile body. The nose cap should be promptly deployed to secure the view field of seeker when it is needed. This cap consists of two nose cap structures and separation devices such as pyro puller and pusher. The performance of pyro puller was fully verified through analyses and several kinds of operating tests. We can obtain a sufficient confidence level of the pyro puller through many operating tests under various environments.
