  • Patent number: 4081155
    Abstract: A heavier-than-air structure has a delta-shaped wing and a plurality of rearwardly-directed flat fans mounted upon the rear thereof. The fans are driven in up and down arcuate oscillations by a rotating shaft carrying flap board assemblies, one board for each fan. The shaft is rotated by a bicycle-type pedal crank driven by the operator of the machine and connected to rotate the shaft by a chain and sprocket. Each flap board engages its corresponding fan forwardly of a pivot axis of the fan, driving the fan downwardly against an opposing force of an elastic band affixed to the fan aft of its pivot point. When the fan is released by continued rotation of the shaft and flap board the fan is returned upwardly by the elastic band. Fanning of ambient air at a rate of two oscillations per second gives sufficient propulsive thrust to drive the machine forwardly.
