Problems solved by technology

[0004] The object of the present invention is to provide a liquid propellant constant pressure spring storage tank, which integrates the storage and supply of the propellant, effectively reduces the volume and mass of the propeller, and solves the problems caused by the previous high-pressure gas extrusion type supply. The volume and mass of the thruster are too large to meet the application requirements of micro-nano satellites

Abstract

The invention belongs to the technical field of liquid propellant electric propulsion systems, and provides a liquid propellant constant force spring storage tank, which includes a box body, a spring support, a constant force spring, a push rod, a piston, a pin shaft, a sealing ring and a guide ring. The sealing ring and the guide ring are installed on the piston to play the role of sealing and guiding; the push rod and the piston are connected, and under the elastic force of the constant force spring, the push rod and the piston squeeze the liquid propellant stored in the tank into the supply pipe road. The invention can ensure continuous and stable supply of liquid propellant under constant pressure, has small volume, light weight and high reliability, and is suitable for electric propulsion system of liquid working medium.

Description

technical field [0001] The invention belongs to the technical field of liquid propellant electric propulsion systems, and relates to a liquid propellant constant force spring type storage tank, which is used for continuous and stable supply of liquid propellant under constant pressure. Background technique [0002] Electric propulsion technology has the characteristics of high specific impulse, high control precision, and long life, and has broad application prospects in satellite attitude and orbit control, deep space exploration and other tasks. The stable and continuous supply of propellant is the key technology of the electric propulsion system. In the past liquid working fluid electric propulsion system, high-pressure gas extrusion is usually used for supply. However, this supply method needs to carry a high-pressure air source and a complete set of air pressure control devices, which will cause a sharp increase in the weight and volume of the thruster. [0003] With t...
