Abstract: The experimental system of hydroreactive metal fuel motor is introduced.The calculational methods for water/fuel ratio,operation pressure and experimental combustion efficiency are put forward,which provide bases for experimental design and performance evaluation.The experiment of hydroreactive metal fuel motor is carried on,and also the propellant component,the motor structure and the water supply system are ameliorated based on the analysis of the experimental results.The experimental results show middle content metal fuel can combust stably after adding water.The combustion efficiency can be improved effectively through the methods of increasing magnesium content in the fuel,keeping water flux invariably and increasing the length of the secondary combustion chamber.
