Abstract

The invention discloses a thruster structure for deeply integrating a hollow cathode into an anode layer hall thruster. In the structure, the core part of the cathode is combined to the inner ring wall surface of the anode layer hall thruster, and the anode plays the role of an original cathode contact electrode. The thruster structure is used for replacing the combination of an original hall thruster and the hollow cathode, so that total mass of an electric propulsion system can be greatly reduced, and the payload is improved.

Description

Technical field: [0001] The invention belongs to the technical field of electric propulsion, and relates to an electric thruster, in particular to an anode layer Hall thruster with a deeply integrated hollow cathode. Background technique: [0002] The Hall thruster is a well-applied electric thruster, which has demonstrated its advantages of high specific impulse, long life, and high reliability in various space missions. Compared with the chemical propulsion system, the use of the Hall thruster is Energy supply can reduce the volume and weight of the system, reduce the quality of the propellant that needs to be carried, increase the actual payload of the satellite, and reduce the launch cost. There are currently two basic configurations of the Hall thruster, which are the Stationary Plasma Thruster (SPT) and the Thruster with Anode Layer (TAL). The core difference between the two is that, compared with In SPT, TAL has a shorter acceleration region, and the wall surface of ...
