Embodiment Construction

[0051] The present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0052] The electromagnetic thruster of the present invention only uses electric energy to generate thrust without carrying fuel. The thruster has a long service life, can greatly reduce the weight of the spacecraft for effective load, has good environmental performance and safety performance, and is small in size and weight. Light is a revolutionary new technology that can greatly improve the performance of spacecraft. The electromagnetic thruster cavity scheme of the present invention is as follows: a microwave resonant cavity with a circular section (including a hemisphere, a truncated cone, and an ellipsoidal cavity) is adopted, and the circular polarization field distribution is designed in the circular section of the cavity, and the design is uneven in the local space of the cavity Energy distribution of electromagnetic field. Compared with the e...

Abstract

The invention discloses an electromagnetic thruster based on circular polarization distribution and a cavity of the electromagnetic thruster. The cavity is a microwave resonant cavity, electromagneticfield distribution of the resonant cavity has the circular polarization characteristic, and under a Cartesian right-angled coordinate system, the section of the microwave resonant cavity is defined to be in a circular shape; an X axis and a Y axis are located in the plane where the section is located, the X axis and the Y axis are orthogonal, and a Z axis is determined through a right hand rule;and an origin O is at the center of the circular section, an electromagnetic field is distributed unevenly in at least one of the X-axis, Y-axis and Z-axis directions. The cavity is provided with twoor more coupling ports; and the resonant cavity having the circular polarization characteristic is applied to the field of electromagnetic thrusters for the first time, the effect that at present, thethruster works stably is achieved, by introducing the design of the circular polarization electromagnetic field, the electromagnetic field resonance mode can be effectively controlled, and the stability of thrust is improved.

Description

Technical field [0001] The invention relates to an electromagnetic thruster based on circular polarization distribution and a cavity thereof, belonging to the technical field of electromagnetic thrusters. Background technique [0002] Electromagnetic thruster is a new concept propulsion technology that has emerged in recent years. This technology uses the uneven distribution of microwaves in a resonant cavity with a specific structure to generate thrust. It is a revolutionary new technology that can greatly improve the performance of spacecraft, and may generate new concept spacecraft based on this technology. [0003] The resonant cavity is a key component of the electromagnetic thruster. Under the condition of an external microwave source, a resonant cavity with a specific shape and a specific internal structure can generate an electromagnetic field with uneven spatial distribution and generate thrust. Therefore, the cavity type and structural design of the resonant cavity are...
