Drum-type storage folding-wing unmanned aerial vehicle

Abstract

The invention relates to the field of unmanned aerial vehicles and provides a drum-type storage folding-wing unmanned aerial vehicle. The drum-type storage folding-wing unmanned aerial vehicle comprises a vehicle body, a double-folding vehicle wing, a propeller and a nacelle. The unmanned aerial vehicle adopts tail-pushing design, the propeller is arranged on the tail of the vehicle body, and the nacelle is arranged on the head of the vehicle body. The double-folding vehicle wing adopts sweepback wing design and is in an X shape when being unfolded. The double-folding vehicle wing comprises a first main wing body, a first winglet body, a second main wing body, a second winglet body and two empennage bodies. The first main wing body and the second main wing body are arranged above and below the vehicle body correspondingly and connected with the vehicle body by penetrating through a rotary shaft of the vehicle body. The ends of the first main wing body and the second main wing body are connected with the first winglet body and the second winglet body through connecting shafts correspondingly, and the tails of the first main wing body and the second main wing body are integrally connected with one empennage body correspondingly. The drum-type storage folding-wing unmanned aerial vehicle has the beneficial effects that through design of the double-folding X-shaped wing, space occupied the ratio of the vehicle wing is shrunk to a great extent when the unmanned aerial vehicle is folded, and a larger vehicle wing area is provided after the unmanned aerial vehicle is unfolded; and propeller conducts tail pushing, the nacelle is located on the front portion of the vehicle body, the filling space of the nacelle is increased, and the more convenient and faster effects are achieved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a folding-wing unmanned aerial vehicle with tubular storage. Background technique [0002] like figure 1 As shown, the front-pull folding-wing submarine-launched UAV is a UAV structure invented by Beijing University of Aeronautics and Astronautics. Its power system consists of a pair of vertically folded paddles 61 at the front of the nose. The wings are divided into left and right sections (62-65), which are folded back respectively. The fuselage is designed to be sealed and waterproof. [0003] However, this layout has many limitations. First, the front-pull structure greatly limits the installation of its pod equipment; secondly, the design of the single-fold wing has a small wing area and provides small lift, and the aircraft needs stronger power In order to maintain the flight, the battery life is reduced; finally, the folding method occupies a large span,...

Problems solved by technology

[0003] However, this layout has many limitations. First, the front-pull structure greatly limits the installation of its pod equipment. Second, the design of the single-fold wing has a small wing area and provides little lift. The aircraft needs stronger power. To keep the flight, reduce its battery life; finally, the folded way occupies a large span dimension, which is not conducive to storage in the launch tube
