Abstract

The invention discloses a solid rocket engine thrust control system and method based on a microwave field. The solid rocket engine thrust control system comprises a combustion chamber shell, an annular heat insulation layer arranged around the inner wall of the combustion chamber shell and an annular grain. An empty runner is formed in the middle of the grain; the inner side of the front end of the combustion chamber shell is connected with the heat insulation layer and the igniter; the igniter is mounted on the inner wall of the grain; the gas outlet end of the combustion chamber shell is sequentially provided with a spray pipe convergent section, a spray pipe throat and a spray pipe expansion section. A pressure sensor, a temperature sensor and a force transducer are distributed on the outer side of the expansion section of the spray pipe, and the pressure sensor, the temperature sensor and the force transducer transmit acquired engine performance parameters to a monitoring terminal through electric signals; the monitoring terminal outputs electric signals to the impedance converter and the microwave power supply according to working condition requirements, the intensity of a microwave field is changed, and thrust regulation and control of the solid rocket engine are achieved. The size of microwave output is adjusted according to working conditions, and thrust regulation and control of the solid rocket engine are achieved.
