Revolving Paddles Lift Odd-Style Plane (Jul, 1933)

Revolving Paddles Lift Odd-Style Plane

Built entirely without propellers as such, but deriving lift from revolving wings which spin in windmill fashion, a unique auto-airplane invented by Paul Lewis, of Denver, Col., gives promise of portending a new trend of development. Principles of its construction are explained in these photographs and drawings. One of the photos shows the lifting wings being tested in the workshop, where they developed a vertical lift of 12 pounds per horsepower. The diagram immediately above shows how lift is obtained.

    What? He built a prototype??

    Didn’t the people in the 20th Century have calculating machines?
    The “Slide Rule”?
    Did anyone ‘run the numbers’?

    Assuming for even a moment that the paddles could be feathered 90 degrees twice per revolution,
    what speed would be required for that surface area to produce sufficient lift to lift the engine, frame, and passengers?
    How strong would the paddles have to be to run at that speed?
    (The photo makes the paddle look flimsy.)

    I call shenanigans on that 12 lbs / horsepower figure.

    I suppose when you are running a magazine during THE Depression, you have to put something between the front and back covers.
