MacCready Solar Challenger
The Solar Challenger was a solar-powered electric aircraft designed by Paul MacCready's AeroVironment. The aircraft was designed as an improvement on the Gossamer Penguin, which in turn was a solar-powered variant of the human-powered Gossamer Albatross. It was powered entirely by the photovoltaic cells on its wing and stabilizer, without even reserve batteries, and was the first such craft capable of long-distance flight. In 1981, it successfully completed a 163 mile (262 km) demonstration flight from France to England.
==History==
The Solar Challenger was designed by a team led by Paul McCready as a more airworthy improvement on the Gossamer Penguin, directly incorporating lessons learned from flight testing the earlier aircraft.〔(Solar Challenger - Exclusive first hand report, of Paul MacCready's solar powered aircraft project ) Martyn Cowley, with drawings by Pat Lloyd.
Aeromodeller, June 1981〕 As with the Gossamer Penguin, construction was sponsored by DuPont in exchange for publicity for the company's patented materials incorporated in the design. AstroFlight, Inc. supplied the motors, which were designed by Robert Boucher.〔 The plane's wings carried 16,128 solar cells yielding a maximum solar power of 3,800 watts.〔 It was flight tested in Western USA in winter 1980-1981.〔("Solar Challenger" by Don Monroe (1981) ) ((Archive ))〕
On July 7, 1981, the aircraft flew 163 miles from Pontoise – Cormeilles Aerodrome, north of Paris, France to Manston Royal Air Force Base in Manston, United Kingdom, staying aloft 5 hours and 23 minutes, with pilot Stephen Ptacek at the controls.〔 Currently the plane is owned by the Smithsonian Institution's Air and Space Museum.〔.〕〔http://www.si.edu/Exhibitions/Details/The-Solar-Challenger-3493〕
