The invention relates to the technical field of spaceflight electric propulsion, in particular to a feeding device. The material supply device comprises a material storage box and a material supply device, wherein the material storage box is used for storing solid iodine particles; the heat conduction net is arranged on the inner wall and the inner bottom of the storage box; one end of the conveying pipeline is connected to the material storage box, and the other end of the conveying pipeline is used for being connected to a thruster; part of the heating assemblies are arranged on the outer wall and the outer bottom of the material storage box, and the other part of the heating assemblies are arranged on the outer wall of the conveying pipeline. When the storage box is filled with the iodine particles, the storage box is heated through the heating assembly, heat is rapidly transmitted to the iodine particles through the heat conduction net, the solid iodine particles are heated and fused, after heating is stopped and the iodine particles are cooled and crystallized, the iodine particles are added again, and the porosity of the iodine particles is reduced through repeated heating and cooling; therefore, the storage density is improved, and the space utilization rate is improved.
Description
technical field [0001] The present invention relates to the technical field of aerospace electric propulsion, and more particularly, to a feeding device. Background technique [0002] With the frequent space activities, the most active technology in the field of space propulsion in recent years is electric propulsion technology. Electric propulsion technology is a technology that uses electrical energy to heat, dissociate and accelerate the working medium to form a high-speed jet to generate thrust. Electric propulsion can bring the advantages of saving thrust agent, improving attitude control accuracy, and expanding deep space exploration distance for spacecraft. It has been widely used in spacecraft such as low-orbit satellites and deep exploration. Ultra-high specific impulse, more modes and lower costs. Ion thrust and Hall propulsion using gas such as xenon as working fluid are relatively mature, and their main feature is the use of high-pressure gas propellant storage...
