Abstract

The gas deflector plate in the solid rocket motor nozzle can make rocket rotate around its vertical axis. The mathematical and physical models of gas deflector plate flow field in the nozzle were established in this paper. The reason of steering moment generated by the deflector and the effect of its structure parameters on rocket guide properties were analyzed using numerical simulationm, and the high-speed rotation test and the exterior ballistic test results were compared with the theoretical results. The results show that the calculation results and experimental ones of the maximum speed of the rocket are in good agreement. The numerical model reliability of the gas deflector plate was verified.

Key words： solid rocket motor; deflector plate; gas; rotating velocity; steering moment
