| Abstract: | 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%. |
