Ejection power device suitable for rocket launching booster

The utility model discloses an ejection power device suitable for a rocket launching booster. The ejection power device comprises an ignition powder box, a combustion chamber, a front powder baffle, arear powder baffle and a fairing. The air tightness, the stability and the coaxiality of the combustion chamber are guaranteed by integrally forming the combustion chamber, and the front and rear medicine blocking plate assemblies are glued by the front and rear medicine blocking plates and the shock pads, so that the assembly is more stable, and the safety is greatly improved. By the adoption ofthe technical scheme, a series of defects of welding variability, large tolerance, unstable assembly and the like of similar ejection devices in China are overcome. 本实用新型公开了一种适用于火箭发射助推器的弹射动力装置，包括点火药盒、燃烧室、前档药板、后挡药板、整流罩。本实用新型通过一体成型燃烧室，保证了了燃烧室的气密性，稳定性和同轴度，通过由前后挡药板和减震垫胶接的前后挡药板组件，使得装配更加稳定，安全性大大提高。采用上述技术方案，解决了国内类似弹射装置焊接易变性，公差大，装配不稳定等一系列弊端。
