Problems solved by technology

[0004] At present, the commonly used working medium of the micropulse plasma constant thruster is polytetrafluoroethylene, and the driving force component for it is generally a supply component based on a constant force spring, that is, a coil spring. The coil spring is used as the spring structure of the driving force, although its The elastic force is relatively stable, but the structural spring needs other accessories to fix it, and the stability is poor, which is not conducive to micro integration

Abstract

The invention discloses a pulsed plasma thruster working medium feeding component. The pulsed plasma thruster working medium feeding component is characterized by simple structure, light weight, and high mechanical properties, and can be integrated and assembled with different pulsed plasma thrusters. High general applicability is provided that a plurality of waist-shaped holes are formed in two sides of a working medium bearing box, and reinforcing bars are formed, a reinforcing bar connecting cover is arranged at the top of the box mouth, a hollow truss structure is formed, weight is reduced, damping is lowered, and the mechanical reliability of the component is improved; and a restraint groove is formed in the center of the bearing box, and an ear piece 15 is arranged on the side face of the corresponding working medium and can be arranged in a restraint groove, so that the restraints of the working medium and spring in the directions of up and down, and left and right are realized,and the stable and reliable directional pushing of the spring and the stable and reliable forward directional movement of the working medium can be effectively guaranteed.

Description

Technical field [0001] The invention belongs to the technical field of spacecraft propulsion, and particularly relates to a working medium supply assembly for a pulse plasma thruster. Background technique [0002] The pulse plasma thruster is a kind of capacitor energy storage, relying on spark plug induction or self-sustained discharge, a large current arc discharge is generated between the anode and cathode electrodes, which makes the working medium ionize into plasma, and sprays under the action of self-induced electromagnetic force and aerodynamic force. A pulsed plasma device that generates thrust is produced. With low power, simple structure, light weight, and easy micro-integration, it is especially suitable for tasks such as micro-nano satellite attitude control, orbit maintenance, and formation flying. [0003] The typical working medium of the pulse plasma thruster widely used at present is polytetrafluoroethylene. The continuous and stable supply of working medium direc...
