Powered glider
Rochelt Solair 1
The Solair 1 was one of the first aircraft that flies with solar energy.
It was developed and built by Günter Rochelt (1939-1998) at his own expense. On August 21, 1983, Rochelt set an unofficial long-term flight record for solar aircraft with the aircraft of five hours and 41 minutes. The history of manned solar flight began in Germany with the Solair 1. As a basis, Rochelt used the "canard design" Canard 2 FL glider from Farner. The wing surface was covered with 2500 solar cells, which were embedded in silicone and then covered with a polyester film. The industrial designer Rochelt was a self-taught specialist in extreme lightweight construction. He also built muscle powered aircraft, such as the Musculair 2, which is on display in the Flugerft Schleißheim museum.
