Description

technical field [0001] The invention relates to a single-component micro-propulsion module device and a supercharging method based on additive manufacturing technology. Background technique [0002] With the rapid development of micro-nano-satellite technology, the complexity of tasks undertaken by micro-nano-satellites has also increased. The formation of a network to build a distributed system has raised certain requirements for the service life, orbital mobility, and rapid response of micro-nano-satellites. Therefore, it is required that the micro-propulsion system has the ability of high total thrust and large thrust, and can be modularized and pre-packaged. The current propulsion system is connected by conventional pipelines, which are heavy and bulky, and are not suitable for use on micro-nano satellites. At the same time, using high-pressure gas to pressurize the system is not conducive to shelf-type long-term storage. Contents of the invention [0003] The techni...
