| 发明名称 | Hall effect plasma thruster with insulated layered ring assembly | ||
| 摘要 | The Hall effect plasma thruster includes a main annular channel for ionization and acceleration that presents an open downstream end, at least one cathode, an annular anode concentric with the main annular channel, a pipe and a manifold for feeding the channel with ionizable gas, and a magnetic circuit for creating a magnetic field in the main annular channel. The main annular channel includes inner and outer annular wall portions delimiting the open end, each of which includes an assembly of juxtaposed conductive or semi-conductive rings in the form of laminations separated by fine layers of insulation. | ||

| 主权项 | 1. A Hall effect plasma thruster having a main annular channel for ionization and acceleration that presents an open downstream end, at least one cathode, an annular anode concentric with the main annular channel, a pipe and a manifold for feeding the main annular channel with ionizable gas, and a magnetic circuit for creating a magnetic field in said main annular channel, wherein the main annular channel has inner and outer annular wall portions delimiting said open end, each of which comprises an assembly of juxtaposed conductive or semi-conductive rings in the form of laminations separated by fine layers of insulation, each of the fine layers of insulation having a thickness smaller than a thickness of said conductive or semi-conductive rings. | ||
