The Gossamer Penguin was a solar-powered experimental aircraft created by Paul MacCready's AeroVironment. [1] MacCready, whose Gossamer Condor in 1977 won the Kremer prize for human-powered flight, told reporters two weeks in June, 1980 that "The first solar-powered flight ever made took place on May 18." [2] The testing ground was at Minter Field outside of Shafter, California. [2]

The Penguin was a three-quarter scale version of the Gossamer Albatross II ; it had a 71-foot (22 m) wingspan and a weight, without pilot, of 68 pounds (31 kg). The propeller was driven by an AstroFlight Astro-40 electric motor, powered by a 541 watt solar panel, consisting of 3920 solar cells. [3]

Initial test flights were performed using a 28–cell, NiCad battery pack instead of a solar panel. The test pilot for these flights was MacCready's 13-year-old son Marshall, who weighed 80 lb (36 kg).

The official pilot for the project was Janice Brown, a charter pilot with commercial, instrument, and glider ratings who weighed slightly less than 100 lb (45 kg). She flew the Penguin approximately 40 times before a 1.95-mile (3.14 km) public demonstration flight at NASA's Dryden Flight Research Center on August 7, 1980. [4]

An electric aircraft is an aircraft powered by electricity. Electric aircraft are seen as a way to reduce the environmental effects of aviation, providing zero emissions and quieter flights. Electricity may be supplied by a variety of methods, the most common being batteries. Most have electric motors driving propellers or turbines.

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.
