Abstract

The invention discloses an electric propulsion testing platform gaseous-propellant supply device which consists of a high pressure gas cylinder, a gas cylinder manual valve, a gas cylinder pressure gauge, a discompressor, a discompressor valve, a discompressor pressure gauge, a metallic hose, a filter in front of a flow controller, the flow controller, a premixing cavity, a pressure sensor, a penetration front manual valve, a penetration flanged joint, an electromagnetic valve, a filter in front of an engine, a tee joint and a stainless steel canaliculus tubule. The gaseous-propellant supply device can propel gas which has single component in certain flow rate and pressure intensity, provides mixed gas propelling agent with certain mixing ratio, and has the advantages of stable work and accurate control of the flow rate.

Description

technical field [0001] The invention belongs to the field of electric propulsion engine tests, and in particular relates to a gas propellant supply device for an electric propulsion test platform. Background technique [0002] As an advanced micro-thrust propulsion method, electric propulsion will play an increasingly important role in the attitude and orbit control, orbit transfer and interstellar navigation of satellites or spacecraft. Resistance heating thrusters, arc heating engines, ion engines, magnetic plasma thrusters, etc. in the electric propulsion family have been extensively studied. The above-mentioned electric propulsion thrust device will select the gas working medium as the propellant for the engine to work. Therefore, the gas propellant supply device is indispensable in the ground simulation test of the electric propulsion engine. [0003] The propellant flow rate is an indispensable parameter for evaluating the performance of the thruster. The ground test...
