Abstract

The invention belongs to the technical field of Hall thrusters, and particularly relates to a Hall accelerator with a sunken hollow inner magnetic pole structure. The Hall accelerator with the sunken hollow inner magnetic pole structure comprises an anode ring, a plurality of inlet and outlet water nozzles, an inner magnetic pole, an outer magnetic pole, an air inlet plate, an air inlet baffle, a support flange, an inner shielding cover, an outer shielding cover and permanent magnets. According to the Hall accelerator with the sunken hollow inner magnetic pole structure provided by the invention, the sunken inner magnetic pole structure design is adopted, so that the device is provided with a completely open leading-out channel, and the size scaling of the device structure is facilitated; and the placement number of the permanent magnets is adjusted, and the anode voltage working range can be greatly improved by adjusting a magnetic field of the discharge area.

Description

Technical field[0001]The present invention belongs to the technical field of Hall thrust, and more particularly to a Hall Accessor having a lower-type hollow polar structure.Background technique[0002]Promotion technology began to receive more and more attention. Compared to the traditional chemical propulsion system, this use of electrical energy treatment and acceleration, by forming a high-speed jet of the ion, thereby generating a technique of thrust, and can save a strong effort and greatly enhance the promotion efficiency. Among the different electric pushers, the application range is a wide range of Hall thrust, and there are two main types of Hall thrust applications in the aerospace field: extended the plasma accelerator (PAEZA) and an anode. The accelerator (AAL) of the layer. Among them, the Hall accelerator accelerates a shorter and accelerating the inner wall of the acceleration channel, which has a conductive properties, has a small secondary electron emission, which is...
