TheGossamer Penguinwas a solar-powered experimental aircraft created byPaul MacCready'sAeroVironment.[1]MacCready, whoseGossamer Condorin 1977 won theKremer prizefor human-powered flight, told reporters in June, 1980 that "The first solar-powered flight ever made took place on May 18."[2]The testing ground was atMinter Fieldoutside ofShafter, California.[2]
ThePenguinwas a three-quarter scale version of theGossamer 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 anAstroFlightAstro-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 thePenguinapproximately 40 times before a 1.95-mile (3.14 km) public demonstration flight atNASA'sDryden Flight Research Centeron August 7, 1980.[4]
