Abstract: An unmanned aerial vehicle includes a body, a plurality of cantilevers and a plurality of driving components. Each cantilever has a first end and a second end. Each first end is opposite to the corresponding second end. The first ends are connected to the body. The driving components are respectively connected to the second ends of the cantilevers. Each driving component includes a motor and a plurality of paddles. The motor has a shaft. The propeller is connected to the shaft and includes a balance disc and a plurality of paddles. The balance disc is connected to the motor. The paddles are connected to the balance disc. The balance disc has a plurality of counterweight holes. The counterweight holes are used to be disposed with the at least one counterweight block. A propeller is also provided.

Abstract: An aerial vehicle and a propeller thereof are provided. The propeller includes a hub and at least one blade. The hub is rotatable about a shaft, and the blade is mounted to the hub. The blade extends from the hub to a tip along a first direction and has a leading edge and a tailing edge opposite to the leading edge. The blade has a section along a second direction in an arbitrary position along the first direction. The second direction is perpendicular to the first direction. A section of the blade in a first position along the first direction has a first peak value of chord length, and a section of the blade in a second position along the first direction has a second peak value of chord length. The second position is between the first position and the tip.
