Ader Avion II
The Avion II (originally referred to as the Zephyr (west wind) or the Éole II) was the second primitive aircraft designed by Clément Ader in 1893.[1] Most sources agree that work on it was never completed, Ader abandoning it in favour of the Avion III that had a financial backer. Ader's later claim that he flew the Avion II in August 1892 for a distance of 100 m at a field in Satory is not widely accepted.Script error: No such module "Unsubst".
Design and development
The name "Avion" was devised by Ader from Latin avis ("bird") and became the origin of the word avion, the most common in French to designate an airplane (heavier-than-air aircraft). The first official text noting it is French patent no. 205 555 granted to Ader on April 19, 1890.Script error: No such module "Unsubst".
