Rocket Motor Injector Housing Module

Abstract

The invention provides a shell module of a rocket engine injector. The invention relates to the technical field of spacecraft propulsion systems, in particular to a shell module structure of a rocket engine injector, which can realize modular integration of engine products. The injector shell module structure according to the present invention includes a power system installation interface, a throttle ring installation interface, an oxidant valve installation interface, a fuel valve installation interface, an injector panel installation interface, a nozzle installation interface, and a combustion chamber pressure nozzle The mounting interface, oxidant flow passage and fuel flow passage are located inside the injector housing module. The invention has the following advantages: 1) The engine product can be modularized and integrated, with compact structure and beautiful appearance; 2) The structure is properly hollowed out, which is beneficial to the weight reduction and thermal protection of the engine product; 3) The number of engine parts can be reduced, thereby improving the inherent reliability of the engine 4) The throttle ring is easy to disassemble and assemble, which is convenient for engine flow resistance adjustment.

Description

technical field [0001] The invention relates to a shell module of a rocket engine injector. Background technique [0002] The engine is the heart of spacecraft such as launch vehicles, satellites, and missiles, and provides power for the spacecraft to change its orbit and attitude. Rocket engines in the fields of launch vehicles, satellites, spacecraft, and lunar exploration generally do not have strict requirements on the weight of the engine and the response of starting and shutting down because the main goals pursued are high specific impulse, long life, and high reliability of the engine. In the field of weapons, the rocket engine pursues the capabilities of small size and fast response, so as to realize the functions of precise strike and fast maneuvering of space offensive and defensive weapons. [0003] The injector is the core component of the rocket engine, which directly determines the combustion performance of the rocket engine. Depending on the application fiel...
