| Abstract: | This paper introduces the experimental equipment and the method of secondary injection based on thrust vector control of SRM.Effect on bow shock wave due to secondary gas injection was investigated with different Mach numbers,gas mass,jet nozzle shape,jet positions and angles.The experimental data obtained from schlieren photograph were compared with the results from the blast wave theory. It proved that the shock slope from the blast wave agreed well with the experimental ones.This experiment provides a good foundation for theoretical calculation research of side thrust on thrust vector control. |
