Abstract
Example embodiments provide a propeller apparatus comprising at least one blade able to twist along a blade twist axis, a hub, a shaft connected to the hub and configured to rotate such that the at least one blade rotates about a shaft axis, and at least one offset propeller unit located in at least one of an upper surface and/or a lower surface of the at least one blade, the at least one offset propeller unit configured to provide thrust. In the propeller apparatus the thrust of the at least one offset propeller unit generates a force to cause the at least one blade to rotate about the shaft axis, and a moment about the blade twist axis of the at least one blade to cause the blade to have a blade pitch angle.
