Description

technical field [0001] The invention relates to the field of propulsion systems, in particular to an integrated satellite propulsion system, especially a novel low-cost integrated liquefied gas miniature propulsion system. Background technique [0002] The propulsion system is a key system for micro-nano satellites to perform tasks such as attitude control, precise positioning, position maintenance, resistance compensation, orbit elevation, and micro-satellite formation flight. For example, a small satellite liquefied gas constant pressure propulsion system and method disclosed in patent document CN106564623B includes a storage tank in which ammonia is stored in a gas-liquid two-phase form; a temperature sensor is installed on the outer shell of the storage tank, and the outlet of the storage tank The tube is equipped with a high-pressure sensor to detect the temperature and pressure in the tank; a heater is installed on the tank to increase the temperature of the tank and a...

AI Technical Summary

Problems solved by technology

[0004] 1. Each functional component of the propulsion system exists in the form of an independent product, which is implemented through pipeline connection. The assembly and welding of tiny pipelines also requires a long production cycle, which makes the system space utilization efficiency low, weight and volume control Difficulty and long development cycle

[0005] 2. Micro-nano satellites are small in size and light in weight. Traditional propulsion systems are difficult to meet the needs of micro-nano satellites for miniaturization and integration of propulsion systems.
