Abstract
Arms and an associated unmanned aerial vehicle (UAV) are disclosed, which include a connecting component, a frame and arms. Each arm includes a longitudinal tube having an inverted teardrop shape-cross section with a hollow interior. The upper end of the longitudinal tube is a first curved surface. The lower end of the longitudinal tube is a second curved surface. The arc length of the first curved surface is greater than the arc length of the second curved surface. The connecting component connects the arm to the frame, and comprises an installing component and a mounting component. The installing component and the mounting component are mounted on two respective ends of the arm. The frame of UAV and the driving assembly are connected through the arm. Compared to circular shape, the raindrop/half lemniscate shape is more streamlined than those having a circular cross-sectional shape, resulting in substantially improved air fluidities.
