Abstract

The invention discloses a propellant supply equipment for electric propulsion engine test. The equipment is applicable to the propellant supply equipment of an electric propulsion engine using liquid or gas as propellants. The gas supply and liquid supply capabilities are integrated into a set of devices so as to solve the problems of propellant flow measurement and control. The design of the liquid and gas line multi-filtering equipment meets the requirement of pipeline cleanliness. A reliable piping layout mode is adopted to achieve the intended functions of the supply equipment, and simultaneously ensure the operation safety, particularly solve the safe operation problem of the toxic propellant similar to hydrazine. The establishment of a set of the devices solves part of the propellant supply problems of the electric propulsion engine using liquid or gas as propellants in the ground experiments.

Description
