| 摘 要： | 针对传统经验公式估算点火药量存在的不足,从固相点火理论出发,推导得到固体发动机点火药量的计算公式.对不同配置的固体火箭发动机进行点火药量验算的结果表明,该公式估算的点火药量与发动机真实试验药量基本一致,估算精度明显优于传统经验公式,且公式通用性较好.

| Abstract: | In order to breakthrough the limitation of traditional engineering empiric formulas for amorce mass estimation, a new method was introduced based on the hypothesis of solid phase ignition. The new formulas was used to estimate the amorce mass for solid rocket motor in different concepts and configurations, and the estimations agreed well with the experiment values. The results show that the new method is superior to classic engineering formulas in estimation precision and applicability. |
