A Honeycomb Dielectric Barrier Discharge Plasma Propulsion Device

Abstract

The invention provides a honeycomb dielectric barrier discharge plasma propulsion device, comprising: a casing, a high-voltage power supply and a honeycomb structure arranged in the casing, along the axial direction of the honeycomb structure, an M A layer of high-voltage electrodes, an M-layer ground electrode is provided at the position where the insulating medium wall intersects with the M-layer high-voltage electrodes, and two adjacent layers of high-voltage electrodes and ground electrodes form a dielectric barrier discharge plasma actuator. The main part of the invention is a honeycomb structure, which is simple in structure, light in weight, and low in manufacturing cost; without moving parts, it responds quickly and has high reliability; by controlling the voltage and frequency of the high-voltage power supply, the excitation intensity and power consumption can be flexibly set, and the thrust can be precisely controlled The direction of thrust can be adjusted by adjusting the direction of the axis of the honeycomb structure. When it is applied to an airship, it can realize precise control of the speed and direction of the airship. It does not need to carry fuel and can realize the long-term resident airship of the airship.

Description

technical field [0001] The invention relates to the technical field of thrusters, in particular to a honeycomb 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] Du...

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.
