Embodiment Construction

[0030] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] Aiming at the problems existing in the prior art, the present invention proposes a new type of micro-UAV using bionic wings. The propeller is differentially used for heading control; a pair of aerodynamic rudder surfaces are installed behind the wings to form a whole micro drone.

[0032] Such as figure 1 As shown, it is an overall schematic diagram of the new micro-UAV of the present invention, including: bionic leading edge 1, main wing 2, power system 3, motor frame 4 and aerodynamic rudder surface 5. The bionic leading edge 1 and the main wing 2 constitute the bionic wing, the main wing 2 is a fixed rectangular wing, and the bionic leading edge 1 is a bionic sinusoidal leading edge with n peaks obtained by processing the straight leading ed...

Abstract

The invention proposes a novel miniature unmanned aerial vehicle using bionic wings, which belongs to the field of miniature unmanned aerial vehicles. The invention includes: a bionic leading edge, a main wing, a power system, a motor frame, and an aerodynamic rudder surface; wherein, the bionic leading edge and the main wing constitute a bionic wing, the main wing is a fixed rectangular wing, and the bionic leading edge is on the fixed rectangular wing. The bionic sinusoidal leading edge with the number of peaks n is obtained by processing on the straight leading edge, n≥3. A new type of micro-UAV proposed by the present invention, by adopting a new type of wing plane with a bionic sinusoidal leading edge, improves the self-induced roll oscillation phenomenon of the micro-UAV under high angle of attack, and improves the flight stability of the aircraft Sex, and simple structure, easy design and processing.

Description

technical field [0001] The invention belongs to the field of micro unmanned aerial vehicles, in particular to a micro unmanned aerial vehicle using a bionic sinusoidal leading edge wing. Background technique [0002] MAVs are a category of drones. The definition of a micro air vehicle is that the flight speed is up to 5-20m / s, and the maximum design length of its fuselage is 10-15cm [1] , has been more and more used in military, civilian, scientific research and other fields [2] . MAVs are mainly divided into three categories, namely fixed-wing MAVs, rotary-wing MAVs and flapping-wing MAVs, among which fixed-wing research is currently the most developed and most widely used type of MAVs. [0003] The aerodynamic characteristics of the small-aspect-ratio wing need to be considered in the design of the fixed-wing micro-aircraft. The small-aspect-ratio wing is vulnerable to instability due to its small aspect ratio and the size of its fuselage span. The influence of the air...
