Electromagnetic propulsion system and method

Abstract

Provided is an electromagnetic propulsion system and method. The electromagnetic propulsion system consists of a signal source, an input control module, a filtering module, a microwave amplification module, an electromagnetic propulsion module and a feedback power control module. The signal source provides a trigger signal and sends the signal to the input control module. The input control module receives the trigger signal sent from the signal source and a feedback signal sent from the feedback power control module and sends the signals to the filtering module. The filtering module filters the trigger signal and the feedback signal and sends the signals to the microwave amplification module. The microwave amplification module amplifies the signals and sends the signals to the electromagnetic propulsion module. The electromagnetic propulsion module converts input power into a thrust. The power of the feedback signal is matched with the input power of the microwave amplification module. Based on the electromagnetic propulsion system and the method, a failure mode caused by frequency drift of an electromagnetic thruster can be solved, the propulsion efficiency and working stability of the electromagnetic propulsion system are greatly improved, and a design method is provided for ground testing and on-track application of the electromagnetic propulsion system.

Description

technical field [0001] The invention relates to an electromagnetic propulsion system and method, relates to an electromagnetic thruster and electromagnetic propulsion, and is suitable for the design of the electromagnetic propulsion system when the electromagnetic thruster is used in a spacecraft. Background technique [0002] In recent years, as a new concept propulsion technology, the lossless electromagnetic propulsion technology has been continuously developed. In order to realize the in-orbit application of massless electromagnetic propulsion, it is necessary to design an electromagnetic propulsion system based on the use strategy of massless electromagnetic propulsion. [0003] The working principle of lossless electromagnetic propulsion is: by designing a microwave cavity (namely electromagnetic thruster) with a specific shape, the electromagnetic field of a specific frequency and mode is distributed in the cavity to become the main mode, and the electromagnetic field...

Problems solved by technology

In actual testing and use, the resonant cavity of the electromagnetic thruster will experience frequency drift due to heat, force, etc., causing its resonant main mode frequency to be far away from the frequency of the input microwave, and the thrust power ratio (that is, the ratio of thrust to input power) cannot be maintained. Constant stable job requirements
