Abstract

The invention belongs to the field of electric propulsion thrusters and discloses a cathode water cooling structure for a magnetoplasma thruster. The cathode water cooling structure is mainly used forsolving the cathode thermal protection problem of the magnetoplasma thruster. The water cooling structure adopts a cathode gripper composed of a cathode connecting part and a cathode water cooling outer shell for clamping a cathode, heat of the cathode is taken away through heat conduction, cooling water flowing reciprocally is used for heat convection in the gripper, and thus heat transmitted from the cathode is taken away. The water cooling structure takes lots of heat settled on the cathode of the thruster in a centralized mode away, an electrode structure is prevented from failing due tooverheat, ablation of the cathode is reduced, and the single working time and the service life of the magnetoplasma thruster are remarkably prolonged.

Description

[0001] Technical field [0002] The invention belongs to the design field of an electric propulsion thruster, and relates to a water cooling structure for cooling a cathode by a holder with an inner cooling channel. Background technique [0003] Electric propulsion is a kind of advanced propulsion method that uses electric energy to directly heat the propellant or ionizes and accelerates the propellant to obtain propulsion power. It has high specific impulse, thrust and efficiency. It has broad application prospects in space missions such as space navigation and interstellar navigation. [0004] The magnetoplasma thruster is a kind of electric propulsion, which uses the Lorentz force generated by the magnetic field and the electric field to accelerate the propellant ionized gas, also known as the Lorentz force accelerator. Magnetoplasma thrusters are easy to combine with high nuclear power, miniaturized, and can provide a greater magnitude of thrust than other electric thrust...
