He was the originator of the use of twisted rubber to power model aircraft, and his 1871 model airplane, which he called the ''Planophore'', was the first truly successful automatically stable flying model. He went on to design a full sized aircraft with many advanced features, but was unable to get any support for the project, and eventually committed suicide in 1880, aged 30. ==Biography== Pénaud was born in Paris into a naval family, his father being an admiral in the French Navy. Because of a hip disease he walked with the aid of crutches and so was unable to attend the Naval School. At 20, he began studying aviation and joined the newly founded ''Société Aéronautique de France''. He became vice-president of the Society in 1876 and participated in the publication of the journal ''L'Aéronaute''. In 1870 Pénaud made the first of a series of successful model helicopters. The principle of this was not new, having been demonstrated to the French Academy of Sciences in 1784 by M. Launoy, a naturalist, and M. Bienvenu.,〔http://invention.psychology.msstate.edu/i/Chanute/library/Prog_Screws_Mar1892.html〕 and was known by Sir George Cayley, but it was the first use of twisted rubber to power a flying model. During the early years of the development of heavier-than-air flight, many experimenters were to use this method of propulsion for experimental models, including Lawrence Hargrave and A.V. Roe. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Alphonse Pénaud」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016. All Rights Reserved.
