Charles LawranceBorn 30 Sep 1882; died 24 Jun 1950 at age 67.Charles Lanier Lawrance was an American aeronautical engineer who designed the first successful air-cooled aircraft engine, used on many historic early flights. He also designed a new type of wing section with an exceptionally good lift-to-drag ratio. His wing design was used widely in World War I. By the mid-1920s his improvements in engine power and reliability made a remarkable series of long-distance flights possible, including those of Admiral Byrd, Charles Lindbergh, Amelia Earhart and Clarence Chamberlin. Despite the sensational publicity of the Lindbergh flight, Lawrance remained in relative obscurity - upon which he commented, "Who remembers Paul Revere's horse?" For his J-5 Whirlwind engine, Lawrance was awarded the annual Collier Trophy in 1928. |
