"Larry Dighera" wrote in message ... 59% increase in pulling power is claimed for an unusual new rotor propeller for airplanes designed on somewhat the same principle as the Flettner rotor sailing ship. Increase over what? Lets see the Wright props already had efficiencies in the eighties, so this guy's prop must deliver more power than it is input. The one I like is the little blades ahead of the prop that are supposed to create a vacuum and increase efficiency. Some of the other "innovations" are actually not lost. The free pivoting wing has been tried a number of times over the years (University of Maryland had one not too long ago on display at Oshkosh).
