Near space electrodynamic patch

Abstract

The invention discloses a near space electrodynamic patch. The electrodynamic patch comprises a positive pole wire, a negative pole wire, a positive pole base, a negative pole base, insulating patches, an upper insulating sheet, a lower insulating sheet and insulating rivets. The electrodynamic patch has the advantages that (1), the electrodynamic patch can be bonded to an outer layer of a low-speed aircraft, independent space as same as the space of propellers is not needed, the thrust force increases as the adhesion area increases, and the electrodynamic patch is particularly suitable for stratospheric airships such as the large-size low speed aircraft; (2), within the height of 20 km to 50 km, as the height increases, the thrust force of the electrodynamic patch under the same voltage increases continuously; (3), the electrodynamic patch has no mechanical motion, no noise and low infrared visibility; (4), compared with propulsion devices such as existing high-altitude propellers, the electrodynamic patch is light in weight and simple in design, and has no rotational torque balance requirements.

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
