FVA-1 Schwatze Düvel
The FVA 1 Schwatze Düvel (Black Devil) was a glider produced in Germany in 1920. It was a highly streamlined, thick winged cantilever monoplane.
==Development==
After World War I aviation in Germany was seriously curtailed by very tight Allied regulation. One loophole in the regulations was gliding, which was virtually ignored. To stimulate interest in the sport, a competition was organised at the Wasserkuppe in August 1920 which became an annual event later known as the Rhön contests. In response, Professor Theodore von Kármán and Wolfgang Klemperer formed an aviation research group at Aachen University called the ''Flugwissenschaftlichen Vereintung Aachen'' (Aachen Flight Research Association) (FVA) to design and build gliders for research and for this competition.〔
For the 1920 Rhön meeting at Wasserkuppe the FVA built a simple monoplane glider. This aircraft, the FVA-1 Schwatze Düvel, was an internally braced, thick airfoil cantilever monoplane with large trousers over landing skids on each side. To keep costs low the aircraft was largely covered in black muslin fabric, donated by the father of a student's girlfriend. Cardboard was used on the wing leading edges and fuselage nose rather than expensive aircraft plywood.〔
The cockpit was on the leading edge of the wing. Conventional stick and rudder pedals controlled the ailerons, elevator and rudder.〔
