【摘要】 探讨了固体火箭发动机点火瞬态一维非定常内弹道模型,综合考虑侵蚀燃烧、加质、摩擦、压力升高速率等因素对内弹道性能的影响,建立控制方程组并采用隐式差分方法结合特征线法求解,应用VC++.NET面向对象技术编制计算机软件。数值算例表明:软件可以进行较为精确的计算并分析发动机点火内弹道影响因素对性能的影响,为发动机内弹道性能计算及火箭发动机工程设计提供了一套更实用的工具。更多还原

【Abstract】 The method of ignition transient interior ballistic calculation of solid rocket motor(SRM) was presented.Many factors influencing the performance of interior ballistic such as erosive burning,friction,pressure velocity were taken into consideration.A CAD software of one-dimensional interior ballistic calculation of SRM was developed with VC++.NET.The numerical examples show that it can basically meet the requirements of the design precision and application.This software is a useful tool for interior ballistic calculation and SRM design.更多还原
