Abstract:
The present invention relates to a blade tip rotary vane which, unlike an existing propeller, is formed by attaching a vane to a blade tip portion at which the rotational speed of the vane is fast, wherein the blade tip rotary vane is characterized in that: the rotational friction of the vanes (102) formed at blade rods (104) around a blade rod hub part (106) is reduced, and the outer surface of the vane (102) is fitted to an outer rotational surface arc in order to prevent the fluttering or vibration of the vanes; the inner surface of the vane (102) is fitted to an inner rotational surface arc; and the outer arc angle and the inner arc angle are the same with respect to the center of a rotary shaft.
