LFU 205
The LFU 205 is a single-engined, four-seat, low-wing monoplane, that was built in the late 1960s entirely from glass reinforced plastic. Only one was produced but this machine continues to fly in a research program into laminar flow over wings. ==Design and development==
The Leichflugtechnik-Union (LFU) was a consortium formed by the Bölkow, Pützer and Rhein-Flugzeugbau companies specifically to produce an aircraft built entirely of glass reinforced plastic (grp). The result, the LFU 205 was one of the first all-grp light aircraft.〔 The LFU 205 is a single-engined, low-winged monoplane of conventional appearance apart from slight, 7° forward sweep on the moderately tapered wing. This carries Fowler flaps along the whole trailing edge inboard of the Frise ailerons. The tail surfaces are also straight tapered, with the vertical surfaces slightly swept. The tailplane is a single piece, all moving surface. There are two pairs of side by side seats under a large curved, rearward sliding, canopy. Fuselage and flying surfaces are monocoque structures using a grp sandwich with a smooth outer surface bonded to a corrugated inner skin, the latter formed from parallel 10 mm (0.4 in) tubes wrapped in glass fibre. The corrugations run chordwise, rib-like, in the wings and tail and circumferentially in the fuselage. The tail structures have a foam plastic core.〔〔 It is powered by a flat 4-cylinder, 200 hp (150 kW) Lycoming IO-360 engine and has a tricycle undercarriage with inward retracting main legs and an aft retracting nosewheel.〔〔 The first flight was on 29 March 1968.〔
