Hybrid rocket motor is a thermochemical propulsion method that stores different phases of fuel and oxidizer separately， which has the advantages of simple structure， low cost and adjustable thrust， making it possess wide applicability in military and commercial fields. However， the low regression rate and imbalance of mechanical properties restrict the development of hybrid rocket engines. This review summarizes the composition， combustion characteristics， laws and key technologies for improving combustion performance of typical hybrid rocket fuels， and analyzes the preparation methods and combustion performances of additive manufacturing fuels. Moreover， the future development directions and trends for advanced hybrid rocket motor fuels are also outlined， which provides insights and references for improving the performance of motors.
