Plasma vector thruster without moving part

Abstract

The invention discloses a plasma vector thruster without a moving part, vector propulsion without a mechanical movement deflection part is realized by combining multi-tube coupling discharge tubes, and a single-tube discharge system of the plasma vector thruster comprises a gas source, a valve, an antenna, grounding electrodes, a discharge tube and a power supply. The gas source is directly connected with the discharge tube through the valve, the valve can independently control gas inlet of each discharge tube, the antenna is embedded in the discharge tube and externally connected with the power supply, the grounding electrodes are sleeved at two ends of the discharge tube, and each antenna can also be independently controlled. The plasma vector thruster is small in space size and total mass, can work in a single-tube mode and a multi-tube combined mode, can achieve thrust from micro-Newton to milliNewton magnitude, can also achieve accurate vector control through multi-tube combination, and is suitable for being equipped with microsatellites for high-precision attitude control and relative orbit position keeping. In addition, the system is of a single-face array type, the structure is compact, the system can be installed on one side of a spacecraft, and the loading space is saved.

Description

technical field [0001] The present invention is suitable for the field of plasma propulsion technology, that is, a micro-propulsion system with high integration, low power consumption, small thrust, and micro-impulse, and can be applied to micro-satellites (micro-satellites, nano-satellites, pico-satellites) flying in formation and forming constellations, Especially for the design of the micro-satellite propulsion system and the realization of the vector thruster, in which the propulsion system is mainly the design of inductive capacitive interactive coupling discharge plasma micro-propulsion, and the vector thruster is mainly through the combination of discharge tubes to realize the angle of the satellite deflection. Background technique [0002] The propulsion system is a key subsystem for a spacecraft to perform tasks such as orbital maneuvering and special attitude control. However, the microsatellites developed internationally in the past two decades are almost not equi...
