Bartelt Ornithopter

   The Bartelt Ornithopter was designed by F. T. Bartelt, J.P., of Corston Lodge, Brislington, Bristol, who was the chairman of the Polysulphin Co. Ltd. The machine was shown at the 1911 Olympia Aero Show, and was powered by a 40 h.p. engine mounted between the lower pair of wings. Chain-drive imparted 50-60 revolutions per minute to the two pairs of movable wings which were superimposed upon each other, acting alternately with a rotary action horizontally. On the upward movement, the wings deflated; when flapping downward, they inflated. The Ornithopter was expected to be able to move backwards or forwards by means of a reversing gear. Each pair of half-wings was 13 ft. in span, with the chord tapering from 12 ft. at the roots to 7 ft. at the tips. Radiators were mounted horizontally on the frames beside the twin seats, behind which was a pusher propeller.
