Patent ID: 7377832

Claim:
A propulsion system for an electric powered flying wing toy, the flying wing having a wing body with a nose and trailing edge, comprising: an electric motor powered pusher propeller mounted aft of the trailing edge; a minimal profile motor enclosure having no horizontal stabilizers and that form-fits to the shape of the electric motor in order to maximize the cross section of smooth air presentable to the propeller, the motor enclosure adapted to extend aft of the trailing edge a predetermined distance that decouples airfoil trailing edge air turbulence from the aft-mounted propeller, the predetermined distance comprising a minimum distance of 20% of the diameter of the propeller; and a smooth, streamlined, featureless top surface between the flying wing nose and pusher propeller having the effect of minimizing obstruction of air upwind of the propeller and maximizing smooth laminar air flow over the wing body; said smooth wing airflow being further improved owing to the effect of partial vacuum between the propeller and the nose when the pusher propeller is engaged.
