Abstract

The invention provides a piston-driven charge structure of a laser-chemical combined propeller. A metal protective shell is sleeved on the charge tube; a fastening head is arranged at one end of the charge tube and is threadably connected with a metal protective shell; the adapter is arranged at the other end of the charge tube; one end of the piston rod is arranged in the charge tube, and the other end protrudes out of the charge tube through the fastening head; the paste propellant is placed in the charge tube; the transmission shaft of the stepping motor is connected with one end of the piston rod protruding out of the charge tube; the three-channel combustion chamber is connected with the adapter; the semiconductor laser is connected with a three-channel combustion chamber, and a glasslens is arranged between the semiconductor laser and the three-channel combustion chamber; the nozzle is connected with a three-channel combustion chamber. The piston-driven charge structure of the laser-chemical combined propellant of the invention is small in volume and light in weight, the paste propellant enters a combustion chamber under the pressure of the piston, the paste propellant combustion is controlled to generate thrust under the laser irradiation, and the thrust adjustment range is in the order of micro-ox to ox, so as to meet the power requirements of micro satellite attitudecontrol and orbit change.

Description

technical field [0001] The invention relates to the design of a thruster, in particular to a piston-driven charge structure for a combined laser chemical thruster, and the charge is a paste-like propellant. Background technique [0002] The existing micro-satellite propulsion system is limited by the size and weight of the satellite, and its charge is low, which leads to the low total thrust of the thruster, which makes it impossible for the satellite to make a large orbital deviation and maneuver, and its orbit changing function is severely limited . 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 pate...
