Modular Bicomponent Propulsion System

Abstract

The invention provides a modular dual-component propulsion system, which also includes: a fuel tank gas bypass module, an oxygen tank gas bypass module, a main gas path module, a combustion agent liquid path module, an oxidant liquid path module and a storage tank Liquid port module; among them, the gas bypass module of the fuel tank is arranged on the left side of the installation space formed by the upper installation plate of the +Y side instrument and the lower installation plate of the +Y side instrument; the oxygen box gas bypass module, the oxygen box gas bypass module Set on the +Y side of the load-bearing cylinder and on the right side of the installation space formed by the upper mounting plate of the instrument on the + / ‑Y side and the lower mounting plate of the instrument on the + / ‑Y side; the main gas circuit module is set on the +Y side of the satellite body On the -Z side of the upper mounting plate of the instrument on the side; the combustion agent liquid circuit module is set on the -Z side of the lower mounting plate of the instrument on the +Y side of the satellite body. The invention adopts a modular layout and moves most of the traditional on-star welding work to off-satellite operations. The operation is simple, the inspection is convenient, and the difficulty of assembly welding is greatly reduced.

Description

technical field [0001] The invention relates to space vehicles, in particular to a modular dual-component propulsion system. Background technique [0002] my country's second-generation geostationary meteorological satellite, that is, Fengyun-4, adopts a dual-component propulsion system and a multi-tank layout plan. The propulsion system needs to complete the tasks of satellite attitude and orbit control and adjustment in each stage, including satellite orbit change maneuver, synchronous orbit fixed-point acquisition, position maintenance, attitude adjustment, etc. The propulsion system has the following functions: helium storage, helium decompression supply, propellant storage, propellant management and distribution, propellant mixing ratio adjustment and balance emission control, as well as orbit changing engine and attitude control thruster execution functions. [0003] Although the dual-component propulsion system of high-orbit satellites has been maturely applied in my...
