Multi-rotor unmanned aerial vehicle

Abstract

The invention discloses a multi-rotor unmanned aerial vehicle. The multi-rotor unmanned aerial vehicle comprises a strip streamlined vehicle body, wherein a plurality of paddle arms symmetrically distributed relative to a symmetry plane in the vehicle body are arranged on the vehicle body; a paddle assembly is arranged at the outer end part of each paddle arm and comprises a motor and a paddle, the motor is mounted on the paddle arm, the paddle is connected to an output shaft of the motor; and the rotation axes of the paddles are located on the same cylindrical surface. According to the technical scheme, on one hand, the resistance of the multi-rotor unmanned aerial vehicle in a flight process can be reduced; on the other hand, the utilization ratio of the volume in the cavity of the vehicle body can be increased, which is beneficial to the upgrade and modification of the multi-rotor unmanned aerial vehicle; besides, the balance and attitude change of the multi-rotor unmanned aerial vehicle having the structural form are simply controlled, and the balance performance is high, so that the seaworthiness of the multi-rotor unmanned aerial vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a multi-rotor unmanned aerial vehicle. Background technique [0002] Unmanned aerial vehicle (unmanned aircraft) is a kind of aircraft that is gradually becoming practical at present. It has the advantages of flexible maneuvering, quick response, unmanned flight, and low operation requirements. Loading multiple types of sensors on UAVs, such as cameras, can realize real-time image transmission and detection of high-risk areas. monitor. At present, most UAVs are designed and manufactured based on the flight principle of helicopters, which can realize vertical lift and high-altitude hovering, so as to meet the requirements of aerial photography and monitoring. The most common ones are single-axis single-propeller, single-axis common propeller and multi-rotor (e.g. quadrotor) form. Generally, there is no casing or only a simple casing on the body of the UAV. The ...

AI Technical Summary

Problems solved by technology

Generally, there is no casing or only a simple casing on the body of the UAV. The UAV without a casing or only a simple casing has poor wind resistance and large flight resistance during flight, which increases the performance of the UAV. consumption, shortening the cruising time of the UAV

In addition, for UAVs equipped with casings, most of the casings are disc-shaped or other irregular shapes. The volume utilization rate of the inner cavity of this structure is low, which is not conducive to the later upgrade of UAVs and the expansion of capabilities. Difference
