System simulation and optimal design of hybrid rocket motor with pump feed system were proposed.The high concentration hydrogen peroxide was selected as the oxidizer.Based on the fact that the high concentration hydrogen peroxide can be easily catalyzed

a pump feed system was used and a system simulation procedure was programmed.The genetic arithmetic was used in the hybrid rocket motor optimal design process.The optimal design results show that hybrid motor with a pump feed system shows more engineering application potential compared with hybrid motor with a gas pressure feed system

because its performances are better.
