Abstract:

In this paper a thrust random maculation of solid rocket motor which is called vortex valve modulation is introduced. The similarity criterion equations of vortex valve modulation performances are obtained, and static characteristics of SRM modulated by vortex valve are also analyzed. The major factors which effect modulation performances and the way how to improve maculation performances for SRM are shown. The thrust maculation performance calculation for a model SRM is conducted. The results are of great reference value to design of vortex valve modulation.
