The HK-12 is a single-engine, two-seat ultralight aircraft manufactured by Leichtflugzeugbau Malchow . It is the first aircraft that was developed in the new federal states after the fall of the Wall .
history
The aircraft designed by Ulrich Horn and Gerhard Köhn was developed in two years at Leichtflugzeugbau Malchow GmbH, which was founded in 1993 . The state government of Mecklenburg-Western Pomerania sponsored the construction of the two prototypes . The first flight of the aircraft ( registration D-MOHK) took place on February 8, 1995 at the Rechlin-Lärz airfield .
construction
The cantilever wing monoplane with normal tail and rigid spur wheel chassis is a fiber composite construction with a rectangular wing in GRP - sandwich construction and GRP / CFRP -Holm. Like the HFL Stratos 300, which Ulrich Horn helped to design, the wing with flaps has a modified Wortmann profile, but thickened by 10%.
The fuselage is a GFK / CFK construction with a low-lying tail unit; behind the cockpit there is a pusher propeller arrangement in the first prototype, a two-cylinder two - stroke engine Göbler-Hirth 2704 with 29 kW and later a two-cylinder four-stroke engine HKS 700E with 44 kW. The one-piece canopy opens to the front, and there are windows on both sides of the cockpit.
