Reflective laser-electromagnetic field coupled thruster

Abstract

The invention relates to a reflecting type laser-electromagnetic field coupling thrustor which comprises a laser system, an electromagnetic accelerating electrode assembly and a static electric fieldassembly. The electromagnetic accelerating electrode assembly comprises an electromagnetic accelerating cathode, an electromagnetic accelerating anode and an electromagnetic accelerating electrode power source; the static electric field assembly comprises a static electric field accelerating electrode, a working medium and a static electric field accelerating power source, the static electric field accelerating power source provides power for the working medium and the static electric field accelerating electrode, and a potential difference is formed between the working medium and the static electric field accelerating electrode to form a static electric field; laser plasmas generated by ablation of the working medium by laser beams enter the static electric field, when the laser plasmas accelerated by the static electric field move to the position between the electromagnetic accelerating cathode and the electromagnetic accelerating anode, discharge arcs can be induced to be generated,the laser plasmas are heated by the discharge arcs and are further ionized, the laser plasmas are sprayed out in an accelerated manner under the joint effect of lorentz force and aerodynamic force, and thrust is accordingly generated. The reflecting type laser-electromagnetic field coupling thrustor has the beneficial effects that the thrust is adjustable, the thrust efficiency is high, and the thrust density is large.

Description

technical field [0001] The invention relates to a novel thruster that provides precise thrust for micro-nano-satellite orbit elevation, position maintenance, attitude control and networking flight, etc., especially relates to a laser ablation plasma generated by laser ablation of solid working fluid, and then used Thrusters accelerated by electrostatic and electromagnetic fields. Background technique [0002] Modern wars and natural disasters have the characteristics of suddenness and localization. Even a huge space system is difficult to achieve complete coverage of the emergency area, and the cost is huge; at the same time, with the continuous development of anti-satellite technology, space The system is becoming more and more fragile, and under extreme war conditions, it faces a serious threat of being destroyed. Therefore, it is necessary to realize the rapid development, rapid launch and rapid application of satellites as an essential means for emergency enhancement an...
