Rotating Blades To Row Planes In Air
JUST as the propeller supplanted the paddle wheel, revolutionizing shipping, so are the new Voith-Schneider vertical feather-blades, successfully tested in Germany, expected to supplant the propeller.
The blades, mounted on a rotating disk, have been used for the past two years on river and harbor boats with marked economies in operation coupled with a decided increase in maneuverability. As the disk rotates, the blades present a full face on the back stroke, and then assume a feathered position for the return circuit. Steering is accomplished by an adjustment which delays the feathering movement, the open faced blades thus pushing the stern of the vessel to starboard or port as desired.
Yup, that’ll work. No Problem.
Sensational German Paddle Plane Built On “Flapping Wing” Principle
FROM Germany comes the news of another attempt to produce a plane of the rotating wing, or “paddle” variety. Unlike the well-known Dr. Rohrbach’s paddle-plane design, the latest attempt to get away from conventional airscrews as a means of propulsion does not depend upon the paddles as a sole means of lift as well as propulsion. Rather, it seeks to adapt the paddle principle to an otherwise normal airfoil.
