Abstract

The invention discloses a propelling agent supply system for a catalytic ignition hydrogen oxygen small-sized rocket thruster test. The propelling agent supply system comprises an air bottle assembly, a flow controller, a solenoid valve, a check valve, a pressure gauge and a connecting device. A fuel hydrogen (H2) pipeline system consists of a test pipeline and an emptying pipeline, wherein the emptying pipeline is used for coarsely adjusting H2 flow and pressure required by the upstream of a catalytic ignition hydrogen oxygen small thrust engine before the test starts, so that the time of coarsely adjusting H2 flow and pressure intensity and the time of H2 passing through the pipeline in the test process can be shortened by the emptying pipeline to the maximum degree.

Description

technical field [0001] The invention belongs to a rocket engine test system, and relates to a propellant supply system for catalytic ignition gas hydrogen oxygen small rocket thruster test. Background technique [0002] The propellant supply system of the gas-hydrogen-oxygen small-scale rocket thruster test using catalytic ignition is a system that provides propellant for the engine and plays an important role in the test. [0003] Compared with traditional chemical propellants, hydrogen and oxygen have advantages such as higher specific impulse, and have always been considered to have great potential in space propulsion. For a long time, the space storage problem of high-pressure hydrogen has not been effectively solved, thus limiting the wide application of hydrogen-oxygen propellants in space propulsion. The water-based rocket space propulsion system can use low-pressure water to electrolyze high-pressure hydrogen in real time, which solves the problem of hydrogen storag...
