Description

technical field [0001] The invention relates to the technical field of micro electric thrusters, in particular to a metal wire explosion-enhanced microcapillary pulse plasma thruster. Background technique [0002] The pulsed plasma thruster is based on the discharge of the spark plug to generate plasma, which causes the discharge of the main energy storage capacitor to form an arc to ablate the surface of the propellant, and the vaporized and decomposed propellant is ejected under the action of electromagnetic force and aerodynamic force to generate thrust pulses plasma device. Pulsed plasma thrusters are mainly used for micro-nano-satellite rotation elimination, orbit positioning (orbit insertion), long-term on-orbit (orbit maintenance), orbit and position adjustment, attitude control, formation flight, and orbit unloading. With the continuous development of aerospace technology, electric propulsion technology has increasingly become one of the symbols to measure the advan...
