Application of Hybrid Rocket Motor in Long-Range Air-to-Air Missile

In order to improve the performance of long-range air-to-air missile based on the basic performances of Phoenix missile and its original solid-propellant rocket motor, a long-range air-to-air missile is designed, in which hybrid rocket motor is taken as the propulsion system and the flight performance of the missile is improved by multiple starts of the hybrid rocket motor. First, a hybrid rocket motor scheme is designed and optimized to replace the original solid-propellant rocket motor by using the multi-island genetic algorithm. Then, a missile model is obtained by parametric simulation of the whole motor. Finally, the aerodynamic estimation, flight simulation, and performance analysis of the missile are carried out. The results show that hybrid rocket motor can significantly improve the range and speed characteristics of long range air-to-air missile, and has a good development prospect.
