Another myth: "The Wright brothers were the first to discover that a propeller is in fact a wing that rotates"

1) "According to Wright historian and retired aeronautical engineer Quentin Wald, the Wrights were the first to think of a propeller as a wing moving on a helical path"
Source: "Discovery of Flight, Wright Experience Prospectus, Propeller Tests To Rediscover the Wright Brothers’ Aeronautical Achievements", 1999, http://www.wrightexperience.com/inde...s/propplan.pdf

2) "Une hélice est un plan qui tombe circulairement et continuellement, tandis que l'aile est un plan qui tombe alternativement."
Source: L'Aeronaute, Year 14, No. 1, January 1881 (see L'Aéronaute (Paris) )

Translation - "A propeller is a plane (surface) that falls (moves) circularly and continuously while a (flapping) wing is a plane that falls alternately."

In conclusion, long before the Wrights started to build planes somebody, in an aeronautical journal, had already had the insight that a propeller is, in fact, a wing that rotates.
