Magnetic plasma thrustor supported through lasers

Abstract

The invention provides a magnetic plasma thrustor supported through lasers. The magnetic plasma comprises a thrustor power source for supplying power to all electric equipment in the thrustor; satellite platform electric energy is converted through the thrustor power source to be then supplied to the thrustor; the magnetic plasma thrustor further comprises a working medium supply device, a negative pole, a positive pole and a laser generation mechanism, a discharge channel is formed between the negative pole and the positive pole, the working medium feeding device used for fixing and conveying a working medium is arranged outside the discharge channel, and the working medium is a solid working medium and extends into the discharge channel; and the laser generation mechanism emits laser beams into the discharge channel to conduct ablation on the working medium, the laser beams conduct ablation on the working medium continuously to generate partial ionized gas and particulate matter, and the partial ionized gas and the particulate matter enter the discharge channel. The magnetic plasma thrustor solves the problems that an air supply system is complex, dynamic response is slow, negative pole ablation is serious, and performance reduction is caused by large-current vibration, and the magnetic plasma thrustor which is supported through the lasers and is high in dynamic response, high in working medium using rate and high in energy conversion efficiency is provided for a spacecraft.

Description

Technical field [0001] The invention relates to an electric propulsion system used for space missions such as spacecraft orbit lifting, deep space exploration, and manned landing on Mars. In particular, it is a magnetic plasma thruster that uses laser gasification and partial ionization of a solid working medium, and is mainly accelerated by electromagnetic force, and works in a quasi-steady state or a steady state. Background technique [0002] Magnetoplasma dynamic thruster (MPDT) is an electromagnetically accelerated electric propulsion system with high specific impulse (1000~10000s), high efficiency (more than 30%), high thrust (can be greater than 10N), and thrust density The Yamato system has the advantages of low mass and has become the most suitable thruster for docking with high-power space solar and nuclear energy systems. It has significant advantages in the orbit promotion of large spacecraft, interplanetary navigation and deep space exploration. [0003] The magnetic ...
