Cylindrical dielectric barrier discharge plasma propelling device

Abstract

The invention provides a cylindrical dielectric barrier discharge plasma propelling device comprising an N-layer cylindrical structure and a high voltage power supply; each layer of the cylindrical structure comprises an insulating dielectric cylinder, and an M-layer high voltage electrode and a M-layer grounding electrode which are staggeredly arranged at two side faces of the insulating dielectric cylinder; the high voltage electrode and the grounding electrode are connected to the high voltage power supply; two adjacent layers of a high voltage electrode and a grounding electrode form a dielectric barrier discharge plasma exciter. The main part of the device is the cylindrical structure which is simple and compact, and is light in weight and low in production cost; the device has no moving parts and has quick response and high reliability; through the voltage and frequency control of the high voltage power supply, the excitation intensity and power consumption can be flexibly set, and the pushing force can be accurately controlled. The direction of the pushing force can be adjusted through adjusting the axial direction of the cylindrical structure; when the device is applied in an aircraft, the moving velocity and moving direction can be accurately controlled without carrying fuel; long-term aerial hovering of aircrafts can be realized.

Description

technical field [0001] The invention relates to the technical field of thrusters, in particular to a cylindrical dielectric barrier discharge plasma propulsion device, which is especially suitable for airships. Background technique [0002] The stratosphere generally refers to the airspace located 18 kilometers to 50 kilometers above the earth's surface. It is the upper hot and lower cold layer in the earth's atmosphere, and it is also the junction of the two systems of earth observation aviation and spaceflight. The stratosphere is the calmest part of the atmosphere, hardly affected by the weather, and almost never wet. At the same time, the stratosphere also has stable meteorological conditions and good electromagnetic characteristics, and there is currently no airspace restriction. Therefore, in view of the stratosphere With its own sports characteristics and unique advantages, it has become a new hot spot for developed countries to compete for space resources. [0003] ...

AI Technical Summary

Problems solved by technology

Since the stratospheric airship needs to stay in the air for a long time, if the traditional propulsion method with fuel is used, it will bring two problems: one is that the fuel carried cannot be supplied for a long time; the other is that with the consumption of fuel, the weight of the airship will change. This is bad for the trim and counterweight of the airship

Therefore, the traditional fuel-carrying engine propulsion system cannot be applied to stratospheric airships, and there is an urgent need for a propulsion device suitable for airships in this field.
