Magnetic propelling device for spacecraft

Abstract

The invention discloses a magnetic propelling device for a spacecraft. The structural design is simple, the propelling device adopts a strip-shaped coil structure, and a higher total coil current can be generated through multi-circle wire-wrap connection of a low current wire; the direction and size of pushing force can be adjusted along with the direction of the coil and the size of the coil current, the direction of the pushing force is vertical to the direction of the coil current, and the spacecraft adopting the magnetic propelling device disclosed by the invention is simpler to control. Compared with a magnetic moment propelling method, the pushing force in a propelling method of the magnetic propelling device for the spacecraft is higher under the environments of equal current intensity and earth magnetic field; moreover, a plurality of propelling devices can be arranged in an overlapped mode for combined use, so that high pushing force propelling of the spacecraft is realized; when the propelling device works, a magnetic field is generated around, space charged particles are deflected under the effect of the magnetic field when getting close to the spacecraft, and the device has certain shielding and protecting effects on the space charged particles for the spacecraft; moreover, the magnetic moment sizes of the propelling devices counteract with each other, and no extract magnetic moment effect is generated for the spacecraft.

Description

Technical field: [0001] The invention relates to a spacecraft magnetic propulsion device, which belongs to the field of spacecraft propulsion systems. Background technique: [0002] The conventional jet propulsion device of spacecraft needs to continuously consume fuel, which restricts its service life and the life of the spacecraft, and at the same time increases the initial launch weight of the spacecraft, thereby increasing the cost of rocket launch and the cost of spacecraft use. Therefore, the propulsion method and device without fuel consumption is one of the main goals in the field of current spacecraft propulsion technology. [0003] At present, the research on propulsion methods for spacecraft without fuel consumption mainly focuses on three directions: electrostatic propulsion, electric tethered propulsion and magnetic propulsion. [0004] The electrostatic propulsion method makes the spacecraft whole with positive or negative charge through space plasma charging ...
