AI Technical Summary
Existing micro-flow control systems occupy a large volume and have flow rates far exceeding the requirements of propulsion systems for micro and nano satellites and other micro-space vehicles. They cannot achieve stable flow supply and precise control, which affects the control accuracy, lifespan and reliability of the spacecraft.
A micro-flow storage and supply system is designed using a purely mechanical gas pressure regulation and control scheme. The system includes a gas storage and control module, a propellant storage and supply module, and a micro-flow control module. Constant output and precise flow control of liquid propellant are achieved through a mechanical pressure reducer and a microfluidic chip.
This invention achieves stable output and precise flow control of liquid propellant in the propulsion system of small spacecraft. The system has a simple structure and high reliability, and is suitable for the storage and supply of propellant under microgravity conditions in space and the ultra-low flow output of liquid working fluid on the ground.
