PADDLE-WHEEL PROPELLERS LIFT AND DRIVE NOVEL PLANE (Feb, 1936)

PADDLE-WHEEL PROPELLERS LIFT AND DRIVE NOVEL PLANE

THRESHING the air like giant paddle wheels, four huge propellers serve the double purpose of lifting and propelling an odd wingless plane designed by two Denver, Colo., inventors. Mounted in pairs on struts jutting obliquely upward from the fuselage, the “propeller wings” have opposing blades fixed on a common shaft at an angle of ninety degrees to each other. An automatic mechanism turns the shafts to “feather” the blades so that each upstroke propels the plane forward and each downstroke provides lift. Drive shafts in the struts connect the blades with the motor in the fuselage. The pilot may control blade pitch to gain either greater speed or more lift.

    i would like to know more about the article “Paddle-wheel propellers lift and drive novel plan”

    I’ve seen this concept at this blog before.

    I suspect it pre-dates the Wright Brothers.

    The paddle plane proponents had no way to calculate the power needed
    or the stresses developed on the blade swiveling mechanism.

    It would be interesting to build a water supported scale model.
    (Like a toy submarine) as a proof of concept.
    (Or disproof, as the case may be.)

    Look at the V-22 Osprey.
    Powerful gas turbine engines make it possible, if not feasible.

    1930s era piston engines would be totally inadequate.

    PS:
    Safwan… Your location… Africa? South East Asia? Some place with a “-stan”?

    jayessell: I think that he’s out of Malaysia
