Embodiment Construction

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments, and the present invention includes but is not limited to the following embodiments.

[0019] The four-axis rotor tilt-rotor solar drone provided by the present invention combines the features of the four-axis rotor tilt-rotor drone technology and the solar powered drone, and mainly consists of a wing-shaped fuselage, a rotor combination, a solar panel, an energy storage It is composed of battery, energy management device, automatic flight control system, support frame and tilting mechanism. For the structure, see figure 1 , see the working principle of solar energy system figure 2 .

[0020] The wing-shaped fuselage adopts a frame structure, and the frame is made of carbon fiber to reduce the structural weight. The surface is skinned, similar in shape to a straight wing, with certain streamlines, asymmetrical double-arc cross-section, and smooth leading ...

Abstract

The invention provides a four-axis rotor wing tilting rotor wing solar unmanned aerial vehicle which comprises a vehicle body, rotor wings, solar cell panels, an energy storage battery and a tilting mechanism; the vehicle body is of a wing-shaped structure, the upper surface and the side face of the vehicle body are covered with the solar cell panel, and the energy storage battery in the vehicle body is charged; the four independent rotor wings are installed on the outer sides, close to the front edge and the rear edge, of the root chord and the tip chord of the wing-shaped vehicle body through the tilting mechanism correspondingly. The unmanned aerial vehicle combines an existing four-axis rotor wing tilting rotor wing unmanned aerial vehicle technology and a solar power technology, has the characteristics of a fixed wing aircraft and a rotor wing aircraft, and has the characteristics of vertical take-off and landing, hovering, rapid cruise flight, long endurance, no pollution and thelike.

Description

technical field [0001] The invention relates to a solar unmanned aerial vehicle, which belongs to the technical field of aerospace. Background technique [0002] Tilting-rotor aircraft is a unique UAV, it not only has the vertical take-off and landing and aerial hovering capabilities like ordinary helicopters, but also cruising flight like propeller planes, with a cruising flight speed (500 mph) faster than ordinary helicopters. km / h or more), great range and maneuverability. This UAV is a high-performance aircraft that combines the characteristics of a helicopter and a fixed-wing aircraft. At present, many researchers believe that this is one of the most promising and most valuable aircraft. Tilt-rotor aircraft can be divided into two categories according to the number of rotors: dual-rotor tilt-rotor (typically represented by the American v-22) and quad-rotor tilt-rotor (typically represented by the QTR and Bell-626 under development in the United States) ). Because th...
