Abstract

The invention relates to the technical field of aerospace, in particular to a control system for a reciprocating type positive displacement pump of a solid-liquid rocket engine. The system comprises astorage mechanism and a liquid pressurizing mechanism; the storage mechanism is used for storing propellant; and the liquid pressurizing mechanism comprises a reciprocating type positive displacementpump, the storage mechanism is communicated with the reciprocating type positive displacement pump, and the reciprocating type positive displacement pump is used for pressurizing propellant and supplying the pressurized propellant to the attitude and orbit control engine mechanism. The liquid pressurizing mechanism is different from a traditional extrusion type or turbine pump pressure type conveying system, a high-pressure gas cylinder and a turbine pump assembly are not used any more, the propellant flowing out of the storage mechanism is pressurized through the light reciprocating type positive displacement pump, and the propellant can have high 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 displacement pump of a solid-liquid rocket engine. Background technique [0002] The attitude and orbit control engine is an important part of rockets, satellites, and upper-level spacecraft, which can determine the maneuverability of the 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 engines and liquid hydrazine engines. Although the structure of the solid rocket engine is simple, it is difficult to switch on and off many times, so it cannot meet the needs of the upper stage in the future. High maneuverability requirements of spacecraft. The liquid hydrazine engine has a large thrust and can be adjusted by changing the flow rate, but the design is complicated, the technology is cu...
