| Abstract: |
| Hybrid rocket motor has many advantages such as high-energy propellants, safety, simplified throttling, multiple starts, high grain stability, low temperature sensitivity, non-pollution and good economy. Hybrid rocket motor meets the requirements of next generation space platforms in respect of environmental protection, intelligent real-time control and rapid launch. Thus, hybrid rocket motor has good application potential in sounding rocket, sub-orbital vehicle, tactical missile, small launch vehicle, booster, upper stage and orbit control power system, lander et al. Hybrid rocket motor has been the new research focus of relative researchers in many countries.This work surveys the development status and trend of hybrid rocket motor, summarizes the typical projects, engineering applications and key technologies. Nowadays, investigations on hybrid rocket motor is mainly intended to make best use of its advantages and avoid the drawbacks. |
