Abstract

The invention discloses a water-based propulsion system and method applied to high-orbit satellites, wherein the system includes a power supply, a water tank, a static water supply proton exchange membrane electrolytic cell, a hydrogen-oxygen management system, and a 100-new level gas-hydrogen-oxygen rail control engine, cow-level gas hydrogen oxygen attitude control engine. The invention solves the problem that the hydrogen-oxygen gas is difficult to manage for a long time in the space environment and the problem that the equivalent mixing ratio of the hydrogen-oxygen gas is difficult to efficiently utilize, and improves the engineering practicability of the hydrogen-oxygen propulsion system on the space flight platform.

Description

technical field [0001] The invention belongs to the field of space propulsion technology, and in particular relates to a water-based propulsion system and method applied to high-orbit satellites. Background technique [0002] Hydrogen-oxygen propulsion is currently the chemical propulsion form with the highest specific impulse. [0003] Water-based propulsion technology is a space propulsion technology based on proton exchange membrane water electrolysis cell (SPE), space gas hydrogen-oxygen engine and hydrogen arc thruster. This technology produces hydrogen and oxygen gas through electrolysis of water and supplies it to the engine to generate thrust. This technology allows the space flight platform to generate a chemical thrust with a specific impulse of more than 360s in orbit only by carrying low-pressure water. It has the characteristics of high specific impulse, green and pollution-free, safe storage, and low cost, and meets the requirements of current space missions f...
