Abstract

The invention discloses a liquid propellant supply assembly for electric propulsion and an electric propulsion system. The liquid propellant supply assembly for electric propulsion comprises a pipeline, and a heating device, a porous material piece, a waterproof breathable film and a pressure reducing valve which are sequentially arranged on the pipeline and are conducted by the pipeline. The invention further provides an electric propulsion system comprising the liquid propellant supply assembly for electric propulsion. The problems that in space electric propulsion, xenon serving as a propellant is high in cost and cannot be massively applied for a long time, and space waste liquid, waste water and available liquid for in-situ resources carried by an aircraft cannot be utilized are solved. The micro-flow supply of the liquid propellant is realized, and the liquid propellant supply assembly has the characteristics of high efficiency, high flexibility, wide application range and long service life.

Description

technical field [0001] The present application relates to the field of aerospace electric propulsion, in particular, to a liquid propellant supply assembly and an electric propulsion system for electric propulsion. Background technique [0002] An electric propulsion system, also known as an electric rocket motor, is a device that generates thrust without relying on chemical combustion. The traditional chemical propulsion system converts chemical energy into mechanical energy through chemical reactions, while the electric propulsion system uses solar energy to convert electrical energy, and then converts electrical energy into mechanical energy. Its advantage is that it no longer needs to use solid or liquid fuel, saving Complex storage tanks, pipelines, engine combustion chambers, nozzles, corresponding cooling mechanisms, etc., can greatly reduce the amount of fuel carried by the spacecraft. The electric propulsion system is generally divided into three parts: power proce...
