Apr 28, 2017 · For our purposes, the most interesting of Alphonse’s interests is, of course, aerodynamics. In 1870, he built a series of successful toy helicopters. The overall design wasn’t all that new, as it was based on experiments that had been around a staggering 86 years at that point. A working toy helicopter was demonstrated in France in 1784 ...
Alphonse Pénaud was born in 1850 in Paris. Pénaud planned to join the Navy. Then he suffered a disabling illness. .... So he turned to inventing a flying machine. He was no idle dreamer. He worked methodically. He thought through questions of stability and propulsion. Pénaud was 21 when he finally perfected a rubber-band-driven model airplane.
Sketch of Penaud’s helicopter. Alphonse Penaud of France invented a toy helicopter in 1870, powered by a rubber band. The toy inspired the Wright brothers to explore human flight.

Alphonse Penaud. A drawing of Penaud's 1871 "planaphore" superimposed on a photo of a vintage planaphore. Penaud and many other manufactures reproduced his designs for rubber-band powered airplanes, helicopters, and ornithopters and sold them as children's toys. Penaud's 1870 helicopter, sans its rubber band.
Penaud's rubber band-powered helicopter. A single rubber band turned both propellers in opposite directions. Alphonse Penaud. 1871: Alphonse Penaud builds what he calls a "planophore," a 20-inch long monoplane with a pusher propeller powered by a rubber band. It flies 131 feet in 11 seconds — the first flight of an inherently stable powered ...
Sep 29, 2002 · A Frenchman, Alphonse Pénaud experimented with toy helicopters, using twisted rubber bands for motive power. It was a Pénaud toy helicopter, given to Wilbur and Orville by their father, that first stirred their childhood interest in flying.
Around 1872 a young French experimenter, Alphonse Penaud, managed to stabilize a rubber-band-powered toy helicopter. He used counter-rotating propellers at either end of a vertical shaft, one above, the other below. Bishop Milton Wright brought a Penaud-type helicopter model home to his boys Orville and Wilbur, and the rest is history.
