Abstract

The invention belongs to the technical field of micro propulsion in aerospace and relates to the MEMS (Micro Electro Mechanical System) technique and the general rocket bipropellant device. A novel liquid bipropellant micro chemical propulsion array is provided by combining the advantages of the current solid and liquid micro chemical propulsion device structures in order to overcome the defects in the prior art. The bipropellant micro chemical propulsion array not only solves the problems on complicated working principle, high requirement of processing and manufacturing technology and low working reliability and the like in the current liquid micro chemical propulsion device, but can simply realize reignition and real-time adjustment of thrusting force and maintain the advantages that the traditional solid micro propulsion system can be distributed in arrays and has high integration level and the like.

Description

technical field [0001] The invention belongs to the field of aerospace micro-propulsion technology, and relates to MEMS technology (micro-electro-mechanical technology) and conventional rocket dual-component propulsion devices. Background technique [0002] MEMS technology (micro-electro-mechanical technology) is a new high-tech development field. It is a micro-miniature mechanical device or component manufactured using microchip technology, integrating micro-mechanical systems, micro-sensors, micro-actuators, control circuits and signal processing. At the same time, the development of MEMS technology in the aerospace field has also been widely used, and the combination with power system technology has greatly promoted the trend of miniaturization and miniaturization of modern rockets and satellites. MEMS micro-propulsion technology is developed by combining MEMS technology and traditional rocket power propulsion technology. As a new technical field, people pay more and more...
