Scheibe Bergfalke
Introduction The '''Scheibe ''Bergfalke''''' (German: "mountain hawk") is a German glider designed by Egon Scheibe as a post-World War II development of the Akaflieg München Mü13 produced before and during the war.
Design and development The prototype flew on 5 August 1951 as the '''Akaflieg München Mü13E Bergfalke I''' and by the end of the year, Scheibe had established his own works at the Munich-Riem Airport to produce the type as the '''Bergfalke II'''. It was a mid-wing sailplane of conventional design with a non-retractable monowheel undercarriage and a tailskid. The fuselage was a welded steel structure covered in fabric and enclosed two seats in tandem. The wings had a single wooden spar and were covered in plywood.Subsequent versions introduced forward sweep to the wings, a more aerodynamic canopy, airbrakes, and a tailwheel in place of the tailskid. By 1982, Scheibe had built over 300 of these aircraft, and Stark Ibérica built a number of the '''Bergfalke III''' version under license in Spain. Scheibe also developed a motorglider version as the '''Bergfalke IVM''' but this did not enter production.In 1976, two Bergfalke motorgliders participated in the Sixth German Motor Glider Competition. Later, one of these aircraft set a world 300 km triangle record.
