Abstract

The present application relates to the field of aerospace technology, in particular to a control system for a reciprocating displacement pump of a solid-liquid rocket engine. The system includes a storage mechanism and a liquid pressurization mechanism; the storage mechanism is used to store the propellant; the liquid pressurization mechanism includes a reciprocating positive displacement pump, the storage mechanism communicates with the reciprocating positive displacement pump, and the reciprocating positive displacement pump is used to pressurize the propellant, And it is used to supply the pressurized propellant to the attitude and orbit control engine mechanism. The liquid pressurization mechanism is different from the traditional extrusion or turbo pump delivery system. This application no longer uses high-pressure gas cylinders and turbo pump components, and uses a lightweight reciprocating positive displacement pump to boost the propellant flowing out of the storage mechanism. The pressure can make the propellant have higher specific impulse performance.

Description

technical field [0001] The present application relates to the field of aerospace technology, in particular to a control system for a reciprocating positive displacement pump for a solid-liquid rocket engine. Background technique [0002] Attitude and orbit control engines are an important part of rockets, satellites, and upper-stage spacecraft, which can determine the maneuverability of spacecraft and the accuracy of orbiting. With the continuous development and innovation in the field of aerospace technology, the existing attitude and orbit control engines are mostly solid rocket motors and liquid hydrazine motors. Although the solid rocket motor has a simple structure, it is difficult to switch on and off multiple times, so it cannot meet the needs of the upper stage in the future. The high maneuverability requirements imposed by the spacecraft. The liquid hydrazine engine has a large thrust and can adjust the thrust by changing the flow rate, but the design is complex an...
