Problems solved by technology

This will bring about two problems. Before the aircraft goes to the sky, after the propellant is filled at the launch base, if there is an emergency and the propellant needs to be released, the metal diaphragm storage tank will be removed from the propulsion diaphragm , needs to be replaced with a new storage tank; and cannot be adapted to the needs of on-orbit propellant filling

Embodiment approach

[0045] The specific functions and implementation plans are as follows:

[0046] like figure 1 Shown: 1 is the gas cylinder, 2 is the filling valve, 3 is the electric explosion valve, 4 is the test port, 5 is the high pressure self-locking valve, 6 is the pressure reducing valve, 7 is the safety valve, 8 is the filling valve, 9 10 is a two-way high-pressure self-locking valve, 10 is a low-pressure self-locking valve, and 11 is a storage tank.

[0047] That is, each storage tank 11 has a gas cylinder 1 to supply extruding gas for it under the normal mode. During in-orbit operation, the electric explosion valve 3 and the high-pressure self-locking valve 5 downstream of the gas cylinder 1 are sequentially opened. After the high-pressure gas is reduced to the rated working pressure through the pressure-reducing valve 6, it enters the air chamber of the storage tank 11, and the gas circuit is completed. supercharged.

[0048] The inventive point of the present invention is that: th...

Abstract

The invention belongs to the technical field of space propulsion. The technical problem to be solved is to provide a realization method of the space propulsion system, which can effectively overcome the defects of the existing technology, and can adapt to the development requirements of long service life and high safety of space vehicles in orbit. The present invention has designed a "well" structure gas path supply system and a cross-supply propellant supply system, and can realize repeated filling / leaking of the propellant on the ground metal membrane box type storage tank, and the present invention brings the following beneficial effects: 1) The air cavities of the two propellant tanks are physically isolated and not connected to each other; 2) Solve the fault isolation of gas leakage, and the system will not fail to work due to the leakage of a gas cylinder; 3) Meet the long-term on-orbit aircraft to adapt to multiple times Supplemented tank design requirements.

Description

technical field [0001] The invention belongs to the technical field of space propulsion. technical background. [0002] On September 21, 1992, China approved the manned spaceflight project and named it "Project 921". Since 1999, the Shenzhou-1 spacecraft successfully entered orbit, which opened the prelude to China's manned spaceflight. After more than ten years of technical reserves and development, it has laid a solid technical foundation for the Chinese space station to be built. The space laboratory serves as the preliminary technology exploration of the space station, and the main technical requirements of the propulsion system are as follows: [0003] (1) The on-orbit working life is 2 years, and the design life is 3 years; [0004] (2) Provide the space laboratory and the combination with the required thrust for orbit change, orbit maintenance, attitude control, attitude correction, etc., and provide power for the unloading of the moment gyroscope. [0005] (3) The...
