Example Embodiment

[0014] figure 1 It is a structural schematic diagram of a high-frequency high-voltage single-electrode plasma thruster of the present invention.

[0015] see figure 1 , a high-frequency high-voltage tip electrode 107 is installed on the center line of a jet tube 105, and the jet tube 105 is fixed on an insulating material 104 provided with an air inlet channel, and the gas of the gas source 101 is passed through the gas in the insulating material 104 Passage 109 enters in the jet pipe 105, and is sprayed out by the mouth of jet pipe, is provided with gas flow switch 102 on gas pipe; The other end of the high voltage and high frequency power supply 108 is connected to the ground. When the line is connected, a high-frequency high-voltage electric field is formed at the end of the tip electrode 107 and breaks down the ionized surrounding gas to form a plasma 106 ejected outward through the nozzle, and the plasma will generate a reverse thrust at the same time. Installed on a s...

Abstract

The invention discloses a high-frequency and high-voltage single electrode plasma thruster. The high-frequency and high-voltage single electrode plasma thruster comprises a point electrode, a gas ejection pipe, a high-frequency and high-voltage power supply and the like, and is characterized in that: the high-frequency and high-voltage point electrode is arranged on the central line of the gas ejection pipe; the gas ejection pipe is fixed on an insulation material with a gas inlet channel; a source gas enters the gas ejection pipe through a gas channel in the insulation material and is ejected outward through a gas ejection pipe opening; the high-voltage point electrode is also fixed on the insulation material and connected with the high-frequency and high-voltage power supply; the other end of the high-frequency and high-voltage power supply is grounded; after a line is conducted, a high-frequency and high-voltage electric field is formed at the end of the point electrode and the gas around ionization is punctured so as to form a plasma ejected outward through a spout; and the plasma produces a reverse thrust at the same time. The system is arranged on a space vehicle so as to thrust the space vehicle in the space.

Description

technical field [0001] The invention relates to a high-frequency and high-voltage single-electrode plasma thruster, in particular to a plasma generator with a single-electrode discharge, which can be installed on a spacecraft and used to propel the spacecraft in space. Background technique [0002] The amount of propellant required to be carried by the aircraft using the electric propulsion system is smaller than that of the chemical propulsion system, thereby increasing the payload on the aircraft or prolonging the life of the aircraft. [0003] Electric propulsion can be used not only as the main propulsion system of the aircraft, but also as an auxiliary propulsion system, such as satellite orbit elevation and adjustment, drag compensation, position maintenance, and orbit entry for geospace and interplanetary navigation. Electric propulsion, which has been extensively studied at present, can be divided into three types: electrothermal, electromagnetic and electrostatic. ...
