The high-precision numerical simulation technology was used to calculate and analyze the evolution law of the shock wave in the launcher before the cover opening, the load distribution of the front cover at different opening times of the rear cover and the bearing deformation of the front cover under different loading modes. The results showed that the shock wave moved axially in the launcher at a speed of about 450 m/s, and the pressure in the center area of the prism cover was greater than that in the inclined area. The longer opening time of the rear cover from the ignition time indicated the greater peak pressure of the gas reaching the front cover. Considering the safety and opening reliability, the performance was optimal when opening the cover at 0.95 ms. Through the research on the gas load distribution of the prismatic fragile front cover, the regional deformation prediction should be carried out according to the platform area and the inclined area. Compared with the average load loading, it is more conducive to the design of the weak parts of the cover.
