Abstract

The invention provides a gas supply assembly. The gas supply assembly comprises a main body structure, a gas cylinder and gas circuit control elements. The main body structure comprises a gas cylindermounting part, a gas circuit mounting part and an external connection part. The gas circuit mounting part is arranged at the upper end of the gas cylinder mounting part. The external connection partis arranged at the lower end of the gas cylinder mounting part. The gas cylinder is mounted on the gas cylinder mounting part and located between the gas cylinder mounting part and the external connection part. The gas cylinder mounting part and the external connection part are matched to clamp the gas cylinder. The gas circuit control elements are mounted on the upper side of the gas circuit mounting part and connected with the gas cylinder. All the gas circuit control elements and the gas cylinder of the gas supply assembly are integrated to the main body structure, so that the gas circuit control elements are mounted conveniently, all the components of the gas supply assembly form an independent module, the final assembly efficiency of a power system is greatly improved, the productioncost is reduced, the structure is compact, space is saved, and the reliability and maintainability of the system are enhanced.

Description

technical field [0001] The invention relates to the technical field of rockets, in particular to an air supply assembly. Background technique [0002] Space orbit attitude control engines are widely used in the upper stages of rockets and satellites, and are the key to the success or failure of missions. The two-component attitude-orbit control power system is widely used in the aerospace field because of its advantages such as high specific impulse, high precision, multiple starts, and wide thrust range. [0003] The gas circuit system in the space-orbit attitude control engine is an important part of the dual-component engine. However, when the gas circuit system in the prior art is installed and used, there are many system components and complicated structural layout, which leads to cumbersome installation and maintenance. Inconvenience and other issues. Contents of the invention [0004] The main purpose of the present invention is to provide an air supply assembly t...
