Miniature coaxial double rotor wings unmanned aerial vehicle

Abstract

The invention relates to a miniature coaxial double rotor wings unmanned aerial vehicle, which comprises a coaxial double rotor wings power system, a lightweight vehicle body and a steering tail rudder system, which are sequentially connected from top to bottom. The coaxial double rotor wings power system comprises an upper rotor wing, a lower rotor wing and a double rotor wings bracket, and the upper rotor wing, the lower rotor wing and the double rotor wings bracket are coaxially arranged; the upper rotor wing is arranged on the double rotor wing bracket; the lower rotor wing is arranged inthe double rotor wings bracket. The lightweight vehicle body is of a streamline hollow structure, and two ends of the lightweight vehicle body are provided with vehicle body curved surfaces which aresymmetrically designed. The steering tail rudder system comprises a steering engine, a steering mechanism and steering rudder wings, wherein the steering engine is arranged on the steering mechanism,and the steering rudder wings are symmetrically arranged on two sides of the steering mechanism. Through the design of the lightweight vehicle body and the coaxial double rotor wings power system, theminiature coaxial double rotor wings unmanned aerial vehicle is light and small, and has a larger weight proportion of the bearable load compared to the weight of the vehicle body, and the angle of the vehicle body can be flexibly adjusted, so that the unmanned aerial vehicle is able to pass through a narrow space and is suitable for the arrangement of the unmanned aerial vehicle fleet.

Description

technical field [0001] The invention relates to a technology in the field of micro-aircraft, in particular to a micro-coaxial dual-rotor unmanned aerial vehicle capable of passing through a narrow horizontal space. Background technique [0002] Micro UAVs are often used for various purposes such as reconnaissance, photography, ground exploration, cargo transportation, etc. However, the low endurance and payload characteristics of the drone itself limit the practical role of the drone in these applications. At the same time, the existing civilian UAVs are mainly quadrotor UAVs, which have the disadvantage that the lateral area is too large and it is difficult to pass through narrow spaces. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention proposes a miniature coaxial dual-rotor unmanned aerial vehicle. Its overall structure adopts a longitudinal structure, so its lateral area is small and can pass through...
