Egg-Beater Wind Plane Imitates Hovering Flight of Eagle (Oct, 1934)
Egg-Beater Wind Plane Imitates Hovering Flight of EagleRevolving blades resembling somewhat the working parts of an egg beater replace wings and tail stabilizers on the “cycloidal flying machine,” an airplane designed to reproduce the best features of an eagle’s flight.
A seven foot model of the unusual craft has already been built in the aeornautical laboratories of the University of Washington by its inventor, Dr. Frederick K. Kirsten. The novel wing mechanism is expected to give higher speeds, hovering flight, and slower landings.
I see eagles with wings like that all the time.
It looks like the Voith Schneider Propeller which works fine in water, so he may not have been too far off (http://en.wikipedia.org…).
he was on the money, this works and as he said it would :
