Transmission type laser-electromagnetic field coupling thruster

Abstract

A transmission type laser-electromagnetic field coupling thruster comprises a laser system, an electromagnetic accelerating electrode assembly, a working medium, a transparent base layer and an electrostatic field assembly. Focused laser beams enter the transparent base layer from a round hole formed in an electrostatic field accelerating positive electrode, the laser beams penetrate the transparent base layer and then erode the working medium, then laser plasma is generated, discharge arcs can be induced to be generated when the laser plasma sequentially penetrates a round hole in an electrostatic field accelerating negative electrode and a round hole in a high-temperature-resisting insulation plate to move to the position between an electromagnetic accelerating anode and an electromagnetic accelerating cathode after being accelerated by an electrostatic field, and the laser plasma is heated and further ionized through the discharge arcs; and a self-induced magnetic field is formed through a fast-changing alternating electric field between the electromagnetic accelerating electrodes, Lorentz force on the plasma is generated under the action of the electromagnetic field, and therefore the higher ionization rate and injection rate of the plasma are achieved, and then thrust pulses are formed. The transmission type laser-electromagnetic field coupling thruster has the beneficialeffects of being adjustable in thrust, high in propulsive efficiency, large in thrust density, small in pollution and the like.

Problems solved by technology

Although APPT has many advantages, it also has the following disadvantages: first, the plume pollution problem; second, there is hysteresis ablation phenomenon, and the propellant utilization rate is low; third, the spark plug ignition failure and easy carbon deposition

However, the working fluid utilization and system efficiency of μLPT need to be further improved to meet the application requirements of micro-nano satellites
