Problems solved by technology

[0003] Due to the considerable weight of medium-sized drones, the rotor will make a very loud sound during flight (the sound produced by the friction of the blades with the air), and for many medium-sized drones, the noise will be very detrimental to its work However, there are relatively few studies on this type of leaf noise reduction
[0004] There are some studies on generalized noise reduction in other fields. For example, in the field of wind power generation, there is research on blade noise reduction. The airflow collides and the aerodynamics are slightly different, so its noise reduction method cannot be directly applied

Embodiment 1

[0031] The utility model relates to a rotating device of a six-wing medium-sized unmanned aerial vehicle, which comprises rotating shafts and blades arranged at the tops of the six wings.

[0032] Three blades are equidistantly arranged on each rotating shaft, and the blades include an upper surface of the blade, a lower surface of the blade, a windward side of the blade and a leeward side of the blade, and a lower side noise reduction component is arranged on the leeward side of the blade. A lower surface noise reduction component is provided on the lower surface of the blade near the leeward side of the blade.

[0033] Both the lower side noise reduction component and the lower surface noise reduction component are strip-shaped rubber strips arranged in a fluffy shape.

[0034] The included angle between the lower side noise reduction component and the leeward side surface of the blade increases as the distance from the rotating shaft increases, the angle between the bar-sha...

Abstract

The invention relates to a rotation device of a six-wing middle-sized unmanned aerial vehicle. The rotation device comprises rotation shafts and blades arranged at the top ends of six wings. By setting noise reducing components on the blades, the noise is obviously reduced during the flight of the middle-sized unmanned aerial vehicle, and thus the hiding property of the unmanned aerial vehicle during flight is perfectly improved.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicle accessories, and in particular relates to a rotating device for a six-wing medium-sized unmanned aerial vehicle. Background technique [0002] The UAV market is gradually expanding, and its application fields are becoming wider and wider. Small drones involve various fields such as film and television, inspection, detection, etc., and their prices are relatively low, so the requirements for details are relatively small. But for medium-sized UAVs, due to their wider application fields and the ability to carry relatively heavy items, research on this type of UAVs has become more in-depth in recent years. Medium-sized UAVs are generally divided into fixed-wing UAVs and rotary-wing UAVs, among which the rotor UAVs are further classified according to the number of rotors. It is good and has been valued by many R&D institutions. [0003] Due to the considerable weight of medium-sized drones, th...
