Abstract

The invention provides an attitude control engine module comprising a module support and engines. A first cavity is formed in the module support. A fluid supply flow channel is formed by the first cavity. A second cavity is formed in each engine. A fluid receiving flow channel is formed by each second cavity. The module support is connected with a transmitter in a fastened manner so that the fluidsupply flow channel and each fluid receiving flow channel can communicate with each other and form a fluid passageway together. Sealing structures are arranged at connection positions of the fluid supply flow channel and the fluid receiving flow channels. According to the attitude control engine module, in practical application, four oxidizing agent flow channels and four fuel flow channels can be formed by the module support through internal punching, the process technology is mature, the mechanical property is good, pipelines are reduced by eight and weld joints are reduced by sixteen compared with traditional design, and the system complexity is lowered.

Description

technical field [0001] The present invention relates to an attitude control power system, in particular to an attitude control engine module, especially an attitude control four engine module. Background technique [0002] According to the traditional design concept, the transmission of propellant is realized through pipelines. Each bicomponent engine is equipped with 2 inlet pipes, and the four-engine unit needs to be equipped with 8 pipelines, involving 16 welds. The piping system is complex, with many welds, poor mechanical properties and low reliability. Contents of the invention [0003] Aiming at the defects in the prior art, the object of the present invention is to provide an attitude control engine module. [0004] The attitude control engine module provided by the present invention includes a module bracket and an engine; a first cavity is arranged inside the module bracket, and the first cavity forms a fluid supply channel; a second cavity is arranged on the en...
