Abstract: An unmanned aerial vehicle (UAV) is provided, which includes a main body; a plurality of frames each extending from the main body; and a plurality of thrust generating devices respectively mounted on the plurality of frames, each of the thrust generating devices including a propeller. The propeller includes a hub that provides a rotation axis of the propeller, and rotates according to an operation of the thrust generating device, and a pair of blades, each of which is pivotably mounted on the hub, and generates a thrust or lift while rotating around the rotation axis as the hub is rotated. The blades are pivotably interlocked with each other such that the blades are aligned to a folded position in which the blades are parallel with each other on the hub in a first arrangement or aligned to an expanded position in a diametric direction of a rotating region of the propeller in a second arrangement.
