Abstract

Vortex valve is a promising approach to realize solid rocket motor thrust modulation. Effects of the flow rate and the pressure of control flow on regulative capability and response characteristics were discussed through cold flow test system. The results show that the operated pressure of vortex valve when the control flow was injected was determined by the pressure of control flow, the regulating ability and response characteristics of vortex valve were improved with the increase of flow rate and pressure of the control flow, under the same pressure variation, response performance of vortex valve were improved with the increase of the flow rate and the pressure of the control flow. The results can provide experimental support for analysis and design of variable thrust solid rocket motor based on vortex valve.

Key words： thrust modulation; vortex valve; old flow test
