Froude, the contributions of the latter continued and enlarged by R. For the forty years following the first flight of the Wright brothers, airplanes used internal combustion engines to turn propellers to generate thrust. Even though both propellers produce the same amount of thrust, the descending blade on the right engine has a longer moment arm, or greater leverage, than the descending blade on the left engine. This picture from the book shows how prop efficiency is related to blade pitch and advance ratio (which is proportional to speed). Propellers: The First, and Final Explanation - isbn 9780962023927.
