Frost Ornithopters
Two of E. P. Frost's ornithopters are among the earliest flapping-wing machines to survive until the present day. The larger, weighing 650 lb. and intended to lift a man, was powered by a steam engine and is preserved by the Shuttleworth Trust. It was made in 1900, and the wings were constructed of cane and silk, with hundreds of natural feathers attached to form a close replica of a pair of bird's wings.
The smaller, of similar construction, was made in 1903 and was 16 ft. in maximum span. Power was by a single-cylinder 3 h.p. B.A.T. petrol engine. This machine is exhibited in the National Aeronautical Collection at the Science Museum. South Kensington, S.W.7 (illustrated).
Neither of these devices succeeded in rising from the ground, but they marked the culmination of more than ten years study of bird flight and a series of ingenious attempts to imitate it by mechanical means.
