Abstract

The invention relates to a rotary driving loading structure for a laser chemical combined propeller. The structure comprises a rotary disc, a rotary steering engine and at least two combustion rooms,wherein the rotary steering engine is connected to the rotary disc and is used for driving the rotary disc to rotate; the combustion rooms are hermetically and fixedly connected to the rotary disc, and the rotary disc rotates to drive the combustion rooms to rotate; each of the combustion rooms is provided with a solid propellant; and the combustion rooms are arranged in parallel, and the rotary steering engine is arranged parallel to the combustion rooms. The rotary driving loading structure for the laser chemical combined propeller provided by the invention is small in size and light in weight, and can meet the power demand on micro satellite orbit control.

Description

technical field [0001] The invention relates to a laser solid micro-thruster, in particular to a rotary-driven charging structure for a combined laser chemical thruster. Background technique [0002] The propulsion system of the existing microsatellites is limited by the size and weight of the satellite, and its charge is low, resulting in the total thrust of the thruster being too low, so that the satellite cannot make a large orbital deviation and maneuver, and its orbit changing function is seriously affected. limit. Increasing the charge amount of the micro-satellite propulsion system will significantly improve the performance of micro-satellites in all aspects, making it easy for micro-satellites to ensure formation flight and complete various tasks. However, the traditional propulsion system is relatively large in size and mass, which is not suitable for the use of microsatellites. [0003] The laser propulsion engine disclosed in patent CN102062019A is a liquid rock...
