摘要
针对某型号固体火箭发动机初始压强峰峰值超差的现象,分别对固体推进剂的能量特性、初始燃烧表面、发动机所用的点火具、测试系统以及发动机的装配过程等可能引起初始压强峰峰值超差的因素,进行了理论分析和实验验证。结果表明,发动机内筒涂层过厚,使得装配完的发动机的初始通气参量变大,同时发动机装配过程不合理,产生从推进剂药柱上刮下来的药屑,这些均导致初始压强峰超标。
Based on the phenomena of initial pressure peak value being high in certain solid rocket motor, the factors that causing the initial pressure peak high： energy properties and initial combustion surface of solid propellant, igniter in motor, testing systems and assembling process of motor are analyzed in theory and validated by experiments. The results show that the thick coat of inner canister in the motor make the initial ventilated parameter of the assembled motor large, and the unreasonable assembling process produces propellant scraps. These all result in initial pressure peak value over high.
