In 1878, the brothers’ father, Milton Wright, brought home a rubber band powered toy helicopter. Designed by French aeronautical experimenter Alphonse Pénaud, this toy did not simply fall to the ground as expected. Rather it "flew across the room till it struck the ceiling, where it fluttered awhile, and finally sank to the floor."
He worked with aeronautical experimenters Alphonse Pénaud and Étienne-Jules Marey. Hureau de Villeneuve had promoted the use of flapping wings ("ornithopter designs") with perhaps 300 experimental models for 25 years since the 1860s, according to Octave Chanute, who discussed an 1872 model in particular.

Dec 17, 2021 · 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. (Image: HNA) In 1870, during the Franco-Prussian War, the Prussian army besieged Paris, Penaud’s hometown. Bored and laid low by a bone disease, the 24-year-old distracted himself by improving on ...
Feb 24, 2021 · As early as November 1809 Sir George Cayley published a masterly essay practically inventing the aeroplane. It lay forgotten for 62 years, until found by Alphonse Pénaud. In August 1871 Pénaud flew his Planophore, the first model to resemble a modern aeroplane. He had discovered the secret of inherent longitudinal stability.
Alphonse Penaud född 1850 död 1880, var en fransk ingenjör. Penaud konstruerade en flygande stavmodell och en helikoptermodell. Stavmodellen visades upp för Le Société Francaise de la Navigation Aérienne som inte insåg betydelsen av dess flygande förmåga.
The Frenchman Alphonse Pénaud was one of the most important figures of the period and was considered by some to be as significant as George Cayley. He theorized about wing contours and aerodynamic principles and applied them successfully to model airplanes, helicopters, and ornithopters. Pénaud used a propulsion system that consisted of ...
