Flying wing layout solar unmanned aerial vehicle

Abstract

The invention discloses a flying wing layout solar unmanned aerial vehicle. The flying wing layout solar unmanned aerial vehicle comprises wings, vertical fins, power pods, non-retractable landing gears, a control surface and a solar cell array, wherein the control surface comprises ailerons, rudders and stabilators; the vertical tails adopt a trapezoidal shape and are arranged at wing tips on the two sides of the wings, the stabilators adopt a rectangular shape and are arranged at the tail parts of the middle sections of the wings, the ailerons are arranged at the trailing edges of the wings, the rudders are arranged at the trailing edges of the vertical fins; the power pods are hung below the wings, the solar cell array is laid on the upper surfaces of the wings, the non-retractable landing gears are arranged below the whole flying wing layout solar unmanned aerial vehicle. According to the unmanned aerial automobile, the scale of the unmanned aerial vehicle can be reduced by virtue of a high pneumatic lift-drag ratio and a light structural weight, and the wind resistance capability of the unmanned aerial vehicle is enhanced through the high flight speed.

Description

technical field [0001] The invention belongs to the technical field of overall design of unmanned aerial vehicles, and in particular relates to a solar unmanned aerial vehicle with flying wing layout. Background technique [0002] Solar UAV is an electric aircraft powered by solar radiation, and it is the product of the combination of aviation science and technology and new energy technology. Solar-powered drones have long cruising time, high flight altitude, wide coverage area, low cost of use, and no pollution to the environment. They can perform various tasks such as communication relay, electronic reconnaissance, and mobile networking. It is an important supplement to flying platforms such as airplanes and high-altitude airships, and has received widespread attention at home and abroad. [0003] Most of the existing solar-powered drones at home and abroad adopt the conventional layout of "wing + fuselage + tail", represented by the "Zephyr" series of the British company...

AI Technical Summary

Problems solved by technology

Conventional layout of solar UAVs has the following disadvantages: (1) The lift coefficient is large, and the flight speed under the same wing load condition is low, resulting in weak wind resistance of UAVs; (2) The fuselage increases the wetted area of ​​the whole aircraft, The lift-to-drag ratio of the whole machine is reduced; (3) The fuselage increases the structural weight of the whole machine, and the tail that is far away from the wing increases the weight of the cables of the whole machine, resulting in a larger scale of the drone
