Abstract

The invention discloses a spiral wave opening system electrostatic ion thruster, and belongs to the technical field of aerospace propulsion of long-life deep space detectors and satellite power systems. The spiral wave opening system electrostatic ion thruster comprises a gas storage tank, a gas supply pipe, a discharge cavity, a spiral wave antenna, an AC electrode and a ring electrode plate. Theworking medium gas in the gas storage tank enters the discharge cavity through the gas supply pipeline, and at the same time, an external radio frequency source supplies power to the antenna, and thehelium gas is ionized inside the discharge to produce spiral wave plasma. Due to the unique double-layer potential difference of spiral wave plasma, the working fluid gas can be accelerated, and other working fluids leave the discharge cavity and enter the ring electrode plate area to accelerate again in the electric field area generated by the ring electrode plate. The spiral wave opening systemelectrostatic ion thruster has the advantages of reduced energy consumption, long service life, low production difficulty and the like.

Description

technical field [0001] The invention belongs to the technical field of space propulsion for long-life deep space probes and satellite power systems, and relates to a helical wave opening system electrostatic ion thruster. Background technique [0002] The helicon wave plasma thruster has attracted extensive attention from scholars at home and abroad because of its high ionization rate, no electrode ablation, long life, and high specific impulse. This new type of thruster will be used in the power system of long-life deep space probes and satellites in the future It has broad application prospects. The helicon wave plasma thruster accelerates the ejection of plasma to generate thrust through the double-layer potential generated inside, but the double-layer potential in the prior art is weak, and the thrust generated is limited, resulting in extremely low overall work efficiency. To deal with this problem, the solutions currently proposed include: rotating electric field acce...
