Abstract

The invention relates to a pulse plasma thruster. In the pulse plasma thruster, an internal cavity isolated from a vacuum environment is formed in a shell, an anode is fixed to the shell, the anode isconnected to the positive electrode of a pulse power supply through an anode connecting wire, the anode is provided with a through hole facing a cathode, and the cathode is fixed to the shell; and the cathode is connected to the negative electrode of the pulse power supply through a cathode connecting wire, a metal wire penetrates through the through hole and abuts against the cathode, the anode,the metal wire and the cathode are exposed in the vacuum environment, and in response to a pulse signal, the metal wire loads pulse current to electrically explode to form plasma.

Description

technical field [0001] The invention belongs to the field of aerospace technology, in particular to a pulse plasma thruster. Background technique [0002] In the field of aerospace, plasma-based electric propulsion technology is the only way for space navigation. However, the traditional plasma thruster based on pulse discharge mainly uses thermal plasma ablation propellant to generate thrust, which has low energy utilization rate, low discharge stability, and poor controllability, which seriously restricts the application of plasma in the aerospace field. application. [0003] The above information disclosed in this Background section is only for enhancement of understanding of the background of the invention and therefore it may contain information that does not form the prior art that is already known in this country to a person of ordinary skill in the art. Contents of the invention [0004] Aiming at the problems existing in the prior art, the present invention prop...
