Research on Liquid CO ₂ Phase Transition Ejection Technology

摘要

Due to the low temperature and clean gas, liquid CO_(2)phase transition ejection technology has outstanding advantages such as high versatility, low launch cost, and environmental friendliness, which will open up a new research field for the development of missile launch technology. Through the study of phase transition characteristics of liquid CO_(2)in this paper, a mathematical model of internal ballistics of the liquid CO_(2)phase transition ejection power system is established. And through simulation calculation, the launching parameters such as the pressure in the launcher, the velocity and acceleration of the missile are obtained, and they is compared with the experiment data to verify the validity of the model.
