"Remarkable Rotor Propeller For Airplanes"

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).

The rotors do add additional energy, as they are rotated by the engine. Of
course, that energy has to come from the engine so there's really no magic here.

You've lost me. If your engine is providing 100 HP, and one prop is 80% effeicient,
you can not make more than one prop deliver 59% more power.

The first one fascinates me!!

George Cornelius: Wing - Popular Science (May 1931) "Free-Winged Plane Able
To Fly Itself"

There was a guy shown on The Discovery Channel (or TLC) maybe 8 years ago,
who recently built one of these - I think it was Down Under. The reporter
flew with him and said it really did smooth out the bumps.

The guy mounted what looked like a PCV tube to the top of the fuselage - it
was a 152 high wing type plane, IIRC. The wings attached to the "pole" and
were free to rotate up and down (forward and back?). I think they were even
independent of each other - port and starboard. Camera caught the wings
doing their thing in flight - they were constantly adjusting to the air -
while the plane flew straight and level.

The STOL characteristics and numbers, according to the "builder" were
unbelievable.

I've always thought this was an idea that made good sense.

Does anyone have any further info on a plane that has pivoting wings?

Thanks for posting the link Larry.

No, but just so people don't think you're crazy(er), I saw the same show.

It was quite remarkable.
