Juge & Rolland Ornithoptère
Thr Ornithopter of Jean-Baptiste Juge and Paul Rolland was designed and realized during 1907 through 1909. In a January 1909 magazine article written by Paul Rolland in “L’Aérophile” about the machine, Rolland begins with a plea to the editor of “L’Aérophile” for a more powerful engine (40 hp), as the one available had insufficient power. In the last paragraph he mentions that the first tests were made without any publicity given. Additionally, he states that the first wing flaps or “coups d’ailes” rather, “have given us every satisfaction.” Jean-Baptiste Juge had filed a French patent on September 28, 1907 (published November 28, 1908) for an “Aviateur”, which is remarkably similar to the finished model. That this patent has only Juge as inventor, gives the impression at least, that he was the driving intellectual force behind the design of the machine.
