Abstract
Aiming at the problems that the former friable lid of the missile was easy to be broken by gas or crashed by missile head in the engineering application, opening process of friable lid of one missile was deeply investigated by means of computational fluid mechanics and experimental method. The results show that the rear friable lid can be opened by nozzle gas, and the former friable lid can be opened by perturbation wave during the launch process when the missile applies the former and rear friable lid technique. Normal opening of the launch lid can be assured by reasonably allocating opening condition of the former and rear friable lid.
