The Performance Characteristic of Hybrid Rocket Engine

The development of hybrid rocket engine in abroad was introduced in this paper. The characteristics of hybrid engine such as specific impulse, adjustable thrust, safety and low cost were demonstrated. The propellant feature of burning behavior and engine in hybrid engine, the differences to liquid and solid engine and the difficulties of technology in development were analyzed. At last, the applied category of the hybrid engines was discussed.
