加液氢固体火箭发动机性能分析

A PERFORMANCE ANALYSIS OF A LIQUID-HYDROGEN-ADDED SOLID ROCKET MOTOR

通过热力计算,分析了固体火箭发动机中加入液氢后对发动机性能的影响.结果表明,加入液氢可以减少燃气成分的分子量,提高发动机的比冲.在所讨论的算例中,比冲最大提高量达4.2%.

The effect of adding liquid hydrogen into a solid rocket motor on the performance of the motor is analysed based on the thermodynamic calculation. It is shown that adding liquid hydrogen is available to reduce the molecular weight of the gaseous components and to increase the specific impulse of the motor. For the discussed example, the specific impulse increases by 4.2%.
