A New Propeller Design

Here a concept for a new propeller is presented. Instead of a single point where a propeller blade is fixed with the aircraft or the ship, I suggest a long axis. The axis runs horizontally. The blades are long rods. They are fixed at one side with the axis. Contrary to the usual propeller, a single propeller blade can be used. The blades may have an arbitrary length. It is limited only by the axis.
