AEA Cygnet
The Cygnet (or Aerodrome #5) was an extremely unorthodox early Canadian aircraft, with a wall-like "wing" made up of 3,393 tetrahedral cells.〔Davies. A. ("Dr. Alexander Graham Bell and Kites." ) ''design-technology.org.'' Retrieved: 3 March 2012.〕 It was a powered version of the Cygnet tetrahedral kite designed by Dr Alexander Graham Bell in 1907 and built by the newly founded Aerial Experiment Association.
==Design and development==
Bell's experiments with tetrahedral kites had explored the advantages of utilizing great banks of cells to create a lifting body leading to the Cygnet I. On 6 December 1907, Thomas Selfridge piloted the kite as it was towed into the air behind a motorboat, eventually reaching a height of 168 ft (51 m). This was the first recorded heavier-than-air flight in Canada.〔("The “Silver Dart” Legacy: Alexander Graham Bell’s Flying Machines of the Future~ A Chronology." ) ''Alexander Graham Bell National Historic Site of Canada,'' 2012. Retrieved: 17 May 2012.〕 While demonstrably able to fly as a person-carrying kite, it seemed unpromising as a direction for research into powered flight. It was difficult to control, and was in fact destroyed when it hit the water at the end of the flight.
The following year, a smaller copy of the design was built as the Cygnet II, now equipped with wheeled undercarriage and a Curtiss V-8 engine.〔Payne 2006, p. 194.〕
