本文对固体火箭发动机的点火作了初步的研究,并通过对影响固体火箭发动机点燃的主要因素的分析、探讨,从而提出了一条新的计算点火药量的公式.本公式综合考虑了装药的形状、装药和点火药的能量、装药的初温、推进剂的性能、燃烧室初始自由容积以及初始燃烧面积等因素的影响.通过对十多种型号的固体火筒发动机点火药量的计算,都能得到比较满意的结果,证明具有一定的普遍性.可供设计和试验时作参考.
In this paper, the ignition of a solid rocket motor is preliminary studied and a new formula for calculating the ignition dosage is proposed by analyzing and discussing the main factors that affect the ignition of the solid rocket motor.This formula takes into account the charge Shape, energy of charge and igniter, initial charge of charge, performance of propellant, initial free volume of combustion chamber and initial combustion area, etc. Through calculating the ignition dose of more than ten types of solid firearm engines, , Can get more satisfactory results, proved to have a certain degree of universality. Design and test for reference.
