Jet-Driven Propeller: Basic research by the National Advisory Committee for Aeronautics in the field of jet-driven propellers may lead to industry development of personal planes similar to this NACA model. The theoretical design uses a pusher propeller without an engine. Driving force would be supplied by reaction from jet nozzles in the propeller tips. Air enters wing scoops, is compressed at propeller hub and by centrifugal action in the hollow propeller blade.
