DFS Rhönsperber

In 1935, Hans Jacobs was asked by Alexander Lippisch to become chief designer of sailplanes at DFS (Deutsche Forschungsanstalt Für Segelflug) at Darmstadt, after the closure the RRG (Rhön-Rossitten Gesellschaft) at the Wasserkuppe in 1933.

Airbrakes are centrally placed on the upper centre section surface and fabric-covered ailerons fill the trailing edges of the outer panels.

[1][2] The canopy is multi-framed with a rather upright windscreen; the fixed glazing extends rearwards to mid wing and the forward section, including the screen, instruments and a small surrounding portion of the fuselage, hinges to starboard for access.

The Rhönsperber has no landing wheel, only a curved main skid reaching from the nose to behind mid-chord, and an integral, pronounced tail bumper.

The following year Peter Riedel gave demonstrations of glider aerobatics at the Winter Olympics, taking off and landing on ice.

[1] Hanna Reitsch also put a Rhönsperber through some vigorous aerobatics, reaching 385 km/h (240 mph) in a dive and losing 1,920 m (6,300 ft) in a forty-two turn, 165 second spin.

[6][citation needed] It is based at the London Gliding Club, Dunstable, and is regularly flown on vintage glider days.
