Solar drone and operating method thereof

Abstract

The invention discloses a solar drone and an operating method thereof. The solar drone comprises a first drone body, a second drone body and a strip-shaped carrier, wherein one end of the strip-shaped carrier is fixedly connected with the first drone body, the other end of the strip-shaped carrier is fixedly connected with the second drone body, and the strip-shaped carrier is provided with solar cell groups; the strip-shaped carrier has a retraction state and a spreading state; in the spreading state, the solar cell groups convert light energy into electric energy provided to the solar drone; in the retraction state, the solar cell groups stop working. Compared with the prior art, the solar drone of the structure has the advantages that the solar cell groups can be adjusted correspondingly according to the size of the strip-shaped carrier, space occupation of the drone bodies is avoided, inconvenience brought to the bodies of the solar drone is avoided, and the solar cell groups can be retracted when not needed.

Description

technical field [0001] The invention relates to the technical field of solar-powered drones, in particular to a solar-powered drone and a method for operating the solar-powered drone. Background technique [0002] There are following technical problems in the solar unmanned aerial vehicle in the prior art: [0003] 1) In order to obtain enough energy, a large area of ​​solar cells usually needs to be laid on the surface of a solar drone, so the practical solar drone body size is very large, which has great impact on the design, manufacture, transportation and use of the drone. posed great difficulties. [0004] 2) Large-scale solar-powered drones have problems such as heavy weight, large wing deformation, prominent aeroelastic problems, and difficult flight control of flexible wings. [0005] 3) Solar cells are usually laid on the outer surface of the wing, fuselage or tail of a solar drone. For the surface of the body, especially the part with a large curvature of the win...

AI Technical Summary

Problems solved by technology

[0003] 1) In order to obtain enough energy, a large area of ​​solar cells usually needs to be laid on the surface of a solar drone, so the practical solar drone body size is very large, which has great impact on the design, manufacture, transportation and use of the drone. brought great difficulty

[0004] 2) Large-scale solar-powered drones have problems such as heavy weight, large wing deformation, outstanding aeroelasticity, and difficulty in flight control with flexible wings.

[0005] 3) Solar cells are usually laid on the outer surface of the wing, fuselage or tail of a solar drone. For the surface of the body, especially the part with a large curvature of the wing head, it is difficult to lay solar cells, so it is usually only laid on the wing The relatively flat part of the rear of the upper wing surface leads to a low utilization rate of the surface of the solar drone body

[0006] 4) Ordinary solar drones are mostly in a level flight posture when they are in use, and can only ensure that the sunlight is close to the vertical solar cell panel incident at noon, but in most of the other time, because the angle between the incident light and the solar cell surface is too large ,low efficiency
