Abstract

The invention discloses a low-power electric arc heating propeller which is mainly applied to a power system for a micro satellite, and belongs to the field of electric propulsion. The low-power electric arc heating propeller aims to solve the problem that an existing micro satellite does not have a propelling system, and a set of complete electric propeller structure is designed according to an electric arc discharge principle between an anode and a cathode. The propeller structure mainly comprises a first cathode clamp seat 1, an upper insulator 2, a middle insulator 3, a lower insulator 4,an air inlet 5, the anode 6, a lower cover 7, a lower nozzle 8, an upper nozzle 9, the cathode 10 and an upper cover 11. According to the low-power electric arc heating propeller, when a voltage between the anode and the cathode achieves an arc-striking voltage, an introduced propellant is heated and expanded, under the action of the nozzles, supersonic gas is generated and ejected, and then reaction thrust is formed; and the low-power electric arc heating propeller has the advantages that integral structure is small in size and light in weight.

Description

technical field [0001] The invention belongs to the field of electric propulsion, and more specifically relates to a low-power arc heating thruster applied to tiny satellites. Background technique [0002] With the development of space mission requirements, higher requirements are put forward for the autonomy, energy saving and rapidity of satellite maneuvering. And micro-satellites with fast maneuverability also have important strategic value and broad application prospects. It can be used as a weapon to complete specific space missions, and can also be used for flight demonstrations and on-orbit operations, such as fault maintenance, on-orbit fuel filling, on-orbit assembly, and space load transfer. one of the important directions. In addition, with the gradual reduction of the technical threshold of micro-satellites, its commercial value has gradually become prominent, such as applications in industries such as communications, agriculture, education, and scientific expl...
