Embodiment Construction

[0028] The specific implementation of the present invention will be described in detail below through specific examples in conjunction with the accompanying drawings. Certain terms are used herein for convenience only and are not to be regarded as limitations of the invention. For example, terms such as "upper," "lower," "left," "right," "horizontal," "vertical," "upward," and "downward" merely describe the configurations shown in the drawings. In fact, components may be oriented in any orientation, and thus the term should be understood to include all such variations unless otherwise indicated. In this specification, the word "comprising" should be understood as its "open" meaning, ie, "having", and therefore should not be limited to the "closed" meaning, ie, "only including". Corresponding meanings also apply to the corresponding words "comprising", "including" and the like. Although expressions such as "1st", "2nd", "first" and "second" may be used to describe the respect...

Abstract

The invention relates to a vector magnetic nozzle composed of interlaced electromagnetic coils for electric propulsion. The vector magnetic nozzle composed of the interlaced electromagnetic coils forelectric propulsion comprises an electric thruster, the first electromagnetic coil, the second electromagnetic coil and the third electromagnetic coil, wherein the electric thruster generates a plasmaflow beam, the first electromagnetic coil, the second electromagnetic coil and the third electromagnetic coil are fixed together in an interlaced mode, certain angles are formed between axes of the first electromagnetic coil, the second electromagnetic coil and the third electromagnetic coil and an axis of the electric thruster respectively, the axes of the first electromagnetic coil, the secondelectromagnetic coil and the third electromagnetic coil are evenly distributed along a space, the first electromagnetic coil, the second electromagnetic coil and the third electromagnetic coil are energized with different magnitudes and directions of exciting currents respectively, the asymmetric vector magnetic nozzle is generated, thus the plasma flow beam is guided to expand and accelerate in arequired direction, and a required thrust vector is generated.

Description

technical field [0001] The invention relates to an electric propulsion structure for a space vehicle, and in particular, relates to a vector magnetic nozzle composed of interlaced electromagnetic coils for the electric propulsion of a space vehicle. Background technique [0002] There are various in-orbit propulsion technologies for spacecraft, and chemical propulsion and electric propulsion are the most widely used at present. Chemical propulsion is the most mature, and it is also the most widely used propulsion technology for my country's space vehicles. Compared with chemical propulsion, electric propulsion has the advantages of reducing the required propellant and prolonging the working time. With the development of electric propulsion technology, more and more spacecraft, such as satellites, have begun to be equipped with electric propulsion systems. [0003] The electric propulsion system includes a magnetic nozzle. The magnetic field lines without actual boundaries...
