| 摘 要： | 通过数值计算 ,分析了燃气流量固定的壅塞式固体火箭冲压发动机、等空燃比工作的固体火箭冲压发动机和非壅塞固体火箭冲压发动机的高度特性和速度特性。结果表明 ,当导弹的飞行高度和速度变化时 ,燃气流量固定的壅塞式固体火箭冲压发动机性能变化最大 ,燃速压强指数为 1 0的非壅塞固体火箭冲压发动机的性能基本实现了等空燃比调节。贫氧推进剂的燃速压强指数越高 ,非壅塞固体火箭冲压发动机燃气流量的自适应调节能力越强。

| Abstract: | The altitude characteristics and velocity characteristics of three types of solid ducted rocket, which are choked solid ramrocket with fixed mass flow rate of fuelrich gas generator, unchoked one and the one working under fixed mass ratio of air to fuel, were numerically studied. The results show that the performance of the unchoked ducted rocket is superior to that of the choked one. When the gas generator is loaded by fuel rich propellant with high exponent, the unchoked ducted rocket can almost be worked under fixed mass flow ratio of air to fuel. |
