Adjacent space electric power patch

Abstract

The invention discloses an electrodynamic patch near space, comprising: an anode wire, a cathode wire, an anode base, a cathode base, an insulating patch, an upper insulating sheet, a lower insulating sheet and an insulating rivet. The beneficial effects of the present invention are: (1) The electrodynamic patch can be adhered to the outer layer of a low-speed aircraft without requiring an independent space like a propeller, and as the adhesion area increases, the thrust increases, which is especially suitable for large-scale low-speed airships such as stratospheric airships. Aircraft; (2) Within the altitude of 20km to 50km, as the altitude increases, the thrust of the electrodynamic patch with the same voltage will continue to increase; (3) The electrodynamic patch has no mechanical movement, no noise, and low infrared visibility; (4) Compared with the existing propulsion devices such as high-altitude propellers, the electric power patch is lighter in weight, simpler in design, and has no requirement for rotational torque balance.

Description

technical field [0001] The invention relates to the technical field of near-space low-speed aircraft power, in particular to a near-space electrodynamic patch. Background technique [0002] At present, the power approach of low-speed aircraft in near space mainly includes the following aspects: (1) Propeller power: It is characterized by the use of propellers with large diameters, which are powered by electricity or fuel to obtain greater thrust near a height of 20km, such as high-altitude The propeller of the airship; the main advantage is that the thrust is large, which can reach more than several thousand cattle. The main disadvantage is that the noise is relatively large, and as the altitude increases, the density of the atmosphere decreases, and the power provided by the propeller decreases rapidly; (2) wind power: Its characteristic is to use the atmospheric wind field in the adjacent space, and the power is formed by the atmospheric wind field, such as a hot air ballo...

[0002] At present, the power approach of low-speed aircraft in near space mainly includes the following aspects: (1) Propeller power: It is characterized by the use of propellers with large diameters, which are powered by electricity or fuel to obtain greater thrust near a height of 20km, such as high-altitude The propeller of the airship; the main advantage is that the thrust is large, which can reach more than several thousand cattle. The main disadvantage is that the noise is relatively large, and as the altitude increases, the density of the atmosphere decreases, and the power provided by the propeller decreases rapidly; (2) wind power: Its characteristic is to use the atmospheric wind field in the adjacent space, and the power is formed by the atmospheric wind field, such as a hot air balloon or a stratospheric balloon; the main advantage is that it does not need to consume additional energy, and the main disadvantage is that it cannot be actively controlled, so it is difficult to completely offset the influence of the atmospheric wind field; (3) Jet power: It is characterized by the use of gas combustion expansion or heating expansion to form a strong power, which is mostly used in high-speed aircraft, such as ramjet engines; the main advantage is that it can form strong power, such as reaching tens of thousands of cattle. , and easy to control, the main disadvantage is that the lower limit of thrust is high, usually above several thousand cattle, and it needs to consume fuel continuously, so it cannot maintain long-term voyage
