Abstract

The invention relates to the technical field of aerospace Hall electric propulsion, in particular to an iodine medium ground gas supply device for a Hall thruster and a using method. The iodine mediumground gas supply device includes an iodine vapor generating unit and an iodine vapor flow control unit, wherein the iodine vapor generating unit includes a solid iodine storage tank and a first pressure sensor. The iodine vapor flow control unit includes a shut-off valve, a pressure relief valve, a second pressure sensor and a flow control valve. The iodine medium ground gas supply device for the Hall thruster adopts an iodine medium propellant to achieve good thrust parameter performance, and the thruster is more efficient. An iodine medium is heated and sublimated into iodine vapor for transportation, the condensation of the iodine vapor in the transportation process is prevented, the flow rate of the iodine vapor can be controlled in real time, and it is ensured that the iodine vaporcan be stably and accurately transported to the Hall thruster.

Description

technical field [0001] The application relates to the technical field of aerospace Hall electric propulsion, in particular to an iodine medium ground gas supply device for a Hall thruster and a method for using it. Background technique [0002] With the development of aerospace technology and the continuous maturity of electric propulsion technology, more and more electric thrusters are being developed and developed by the aerospace industry of various countries. Compared with traditional chemical thrusters, electric thrusters have the characteristics of high specific impulse, long life, compact structure, and small size, and have significant application prospects in satellite attitude control, orbit correction, orbit maintenance, and power compensation. [0003] Among many electric thrusters, the Hall thruster has attracted widespread attention because of its simple structure, easy operation, and high utilization of working fluid. The mainstream Hall thruster propellant is...
