Small unmanned aerial vehicle adopting linked wing type pneumatic layout

Abstract

The invention discloses a linked-wing small solar unmanned aerial vehicle. The unmanned aerial vehicle comprises a front fuselage and a rear fuselage, front-end sweepback wings and rear-end sweepforward wings, a double-engine motor and propellers which are arranged at the front ends of the two fuselages, bridge arms which are connected with the front and rear wing sections, two motors and propellers which are arranged on the outer sides of the left bridge arm and the right bridge arm, and an inverted vertical fin which is connected with the rear fuselage. The upper surfaces of the left sweepback wing, the right sweepback wing, the left sweepforward wing and the right sweepforward wing of the wings are each provided with a solar cell panel set, and energy is provided for continuous flight of the unmanned aerial vehicle. During takeoff, the left and right propellers can be used for vertical takeoff and landing, so that the usability and takeoff stability of the aircraft are improved; the maneuvering characteristics and higher reliability of the aircraft are improved through control of multiple groups of propellers; the inverted vertical fin can replace an undercarriage as a support, so that the structure is simplified and the weight is saved; the unmanned aerial vehicle is not provided with an undercarriage, can realize short-distance throwing flight without a runway requirement during take-off, realizes gliding landing during landing, and also can realize vertical take-off and landing and hovering.

Description

technical field [0001] The invention relates to a small unmanned aerial vehicle adopting a wing-linked aerodynamic layout. Background technique [0002] Low-altitude solar-powered aircraft has many advantages, such as: providing a communication platform for remote and mountainous areas; taking ground pictures at close range with high resolution, which can detect forest fires, search and rescue, etc., and has a wide range of applications. Generally, small low-altitude UAVs that rely on their own fuel as a power source have the problems of less range, short time to stay in the air, and severe restrictions on the height of the air. In addition, in some cases, small drones are required to perform high-mobility tasks. Due to the low take-off weight of the drone itself, it cannot carry enough fuel, which will not meet the requirements of the flight mission. [0003] Taking border reconnaissance as an example, the use of reconnaissance aircraft in active service will be affected b...
