Embodiment Construction

[0032] Such as Figure 3-9 As shown, an axial gap adjustment structure at the high temperature end of a Hall thruster of the present invention is composed of a metal base 1 , a metal rubber pad 2 and a ceramic channel 3 . The three parts are arranged coaxially, and the metal rubber pad 2 is fixed in the groove of the metal base 1 . The three realize stable and reliable connection with other parts in the Hall thruster through screws.

[0033]The metal base 1 is a ring structure, including a first cylindrical surface, a second cylindrical surface, a third cylindrical surface, a first end surface, a second end surface and a third end surface. The first cylindrical surface is the cylindrical surface with the largest diameter in the metal base 1, and its diameter is D1. The third cylindrical surface is the cylindrical surface with the smallest diameter in the metal base 1, and its diameter is D3. The diameter of the second cylindrical surface is D2. The relationship among D1, D...

Abstract

The invention relates to an axial gap adjustment structure at the high temperature end of a Hall thruster, comprising a metal base, a metal rubber pad and a ceramic channel; the above three components are coaxially arranged, and the metal rubber pad is fixed in the groove of the metal base; the above The three realize stable connection with other parts in the Hall thruster through screws. The invention adopts the structure composed of metal base with groove, metal rubber pad wound by stainless steel wire, and channel ceramics, so as to adapt to the gap change caused by temperature change before and after the thruster works.

Description

technical field [0001] The invention relates to an axial gap adjustment structure at the high temperature end of a Hall thruster, which is suitable for the Hall thruster or other occasions requiring gap adjustment in high temperature areas. Background technique [0002] Hall propulsion technology is the mainstream technical direction of spacecraft electric propulsion at present. The Hall thruster mainly includes hollow cathodes, discharge chambers, magnetic poles, magnetic coils, anode / gas distributors, propellant delivery pipelines and support structures; Seoul propulsion technology can increase the payload of spacecraft, reduce launch costs, and extend service life. It is an effective means to improve the efficiency and competitiveness of commercial satellites in the future. [0003] Hall thruster consists of hollow cathode, discharge chamber, magnetic pole (composed of front and rear magnetic pole plates, inner and outer magnetic cores, inner and outer magnetic screens, e...
