    Abstract
  • Numerical calculation and experimental study on the performance of the variable control flow supply angle regulation scheme of vortex valve solid rocket motor were carried out. Numerical results showed that the variable control flow supply angle regulation scheme can be used to achieve a very good performance, the maximum thrust regulation ratio of the vortex valve solid rocket motor exceeded that of the straight mass augmentation motor by 26%, and the pressure ratio increased with the decrease of the control flow supply angle. Experimental results showed that the variable control flow supply angle regulation scheme was feasible and the superiority of “gasgas” regulation was verified. The variable control flow supply angle regulation scheme provided a technical approach for the realization of thrust regulation of solid rocket motor.
