Winglet rotation device of minitype fixed wing unmanned aerial vehicle

Abstract

The invention relates to a winglet rotation device of a minitype fixed wing unmanned aerial vehicle. The winglet rotation device of the minitype fixed wing unmanned aerial vehicle comprises an unmanned aerial vehicle frame, a winglet and a rotation mechanism. The unmanned aerial vehicle frame is composed of an unmanned aerial vehicle body, an open-source flight controller, am electronic governor, a motor and a propeller, wherein an unmanned aerial vehicle main wing segment is made of an EPP foam material, is light in specific gravity and good in elasticity, and is widely applied to remote sensing unmanned aerial vehicles; and an unmanned aerial vehicle wingtip segment is made of a balsa wood material, and the main wing segment and the wingtip segment are fixedly connected together. The rotation mechanism is composed of a biaxial motor and a connecting plate. The electronic governor is controlled by the flight controller, then the biaxial motor is controlled to rotate, and finally the angle of the winglet is adjusted, to automatically adapt to the change of the flight attitude of the unmanned aerial vehicle. The winglet rotation device is diverse in adjustable angles, and the flight attitude of the unmanned aerial vehicle is automatically identified by using the flight controller, so that the angle is adjusted more timely, the aerodynamic performance of the wings is better improved, and the endurance and voyage of the unmanned aerial vehicle in operation are increased.

Description

technical field [0001] The invention proposes a fixed-wing unmanned aerial vehicle device equipped with modified winglets, and particularly relates to the field of overall layout design of remote sensing fixed-wing unmanned aerial vehicles. Background technique [0002] As a kind of UAV aircraft, fixed-wing UAV has the advantages of high flight efficiency, simple system structure and low cost. It has been more and more widely used in large-scale cruise monitoring, making up for the satellite remote sensing data acquisition ability Insufficient, long update cycle and other shortcomings. The current drones have shortcomings such as short flight time and small task load, and cannot well meet the long-term, long-distance aerial photography, surveying and mapping tasks. [0003] Because winglets can improve the spanwise flow of airflow and reduce wing-induced drag, and have the advantages of increasing lift and reducing drag, increasing climb rate, and increasing flight time and...
