Description

Technical Field

[0001] The present invention relates to the field of aerospace electric propulsion technology, and more specifically, to a method and device for measuring the velocity of a field-reversed electric propulsion plasma cluster. Background Art

[0002] Field-reversed electric propulsion for space is an advanced aerospace propulsion technology. Its principle is to use space electrical energy to ionize propellant to produce a high-density plasma. This is then driven by a rotating magnetic field system to form a circular current. This current couples with an external magnetic field to generate an electromagnetic Lorentz force, which accelerates the ejection of electrons and generates thrust. Due to the pulsed operating mode and electromagnetic acceleration mechanism of field-reversed electric propulsion, conventional diagnostic and testing methods are difficult to meet application requirements. Conventional methods for measuring plasma mass velocity are relatively simple and have low measurement accuracy, which has hindered its development into commercialization. Summary of the Invention
