Gossamer Albatross
From open-encyclopedia.com - the free encyclopedia.
The Gossamer Albatross was a human-powered aircraft built by Dr Paul B MacCready. On June 12, 1979 it completed a successful crossing of the English Channel to win the second Kremer prize.
The aircraft was powered using pedals to drive a large two-bladed propeller. Piloted by professional cyclist Bryan Allen it completed the 35.8 km crossing in 2 hours and 49 minutes, achieving a top speed of 29 km/h (18 mph) and an average altitude of 15 metres.
The aircraft is of unusual configuration, using a large horizontal stabilizer forward in a manner similar to the Wright brothers successful craft. The Gossamer Albatross was constructed using plastic over a carbon fibre frame, with the structure of the wings provided with expanded polystyrene ribs. The entire structure was then wrapped in a thin, transparent plastic (MylarŪ). The empty weight of the structure was only 32 kg, although the gross weight for the Channel flight was almost 100 kg. To maintain the craft in the air it was designed with very long tapering wings, like those of a glider, allowing some of the flight to be undertaken with a minimum of power.

The aircraft was designed and built by Paul B MacCready, a noted US aeronautics engineer, designer and glider pilot, and Gossamer Albatross was his second human-powered aircraft. The first was the Gossamer Condor which won the first Kremer prize on August 23, 1977 by completing a figure eight course.
MacCready's team built two Albatrosses, the back-up plane was jointly tested as part of the NASA Langley/Dryden flight research program in 1980. Part of this testing included flights inside the Houston Astrodome, the first ever controlled indoor flights by a human-powered aircraft. The Albatross II is currently on display at The Museum of Flight in Seattle, Washington.
A follow-up to the Albatross was the solar-powered Gossamer Penguin in 1980.
