Integrated satellite propelling system

Abstract

The invention provides an integrated satellite propelling system which comprises an integrated body structure (1), a feeding and discharging valve (2), thrusters (3), support structures (17) and a detection device (8). The integrated body structure (1) is of a ring-shaped structure. The support structures (17) are arranged on the integrated body structure (1), and the support structures (17) is provided with thruster connecting openings. The thrusters (3) are arranged on the thruster connecting openings. A cavity structure is arranged in the integrated body structure (1). A runner (14), a propellant storage cavity (15) and a propellant management structure (16) are arranged in the integrated body structure (1). The runner (14) can communicate with the thruster (3), the detection device (8)and the propellant storage cavity (15). The requirement for microminiaturization and integration of micro-nano satellites for the propelling system is met.

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.
