Abstract

The separation process of the frangible cover of the launcher is complex and the safety is unknown.For this, the numerical calculation, impact cover opening test and shock wave cover opening test were studied. Firstly, integrated design of the frangible cover with new composite material. Secondly, the flow field in the launcher is calculated by computational fluid dynamics, we acquired the pressure distribution in the launcher and the time-pressure curve of frangible cover, and we simulated the shock wave opening process. Finally, the availability and reliability of the design are verified by impact frangible cover test and flight test. The analysis results show that the impact opening of the frangible cover can satisfy the design requirements, and the simulation results of shock opening are consistent with the experimental results.

Key words： launcher; frangible cover separation; numerical calculation; shock wave opening process
