The LCF II is a single seat Club Class glider, designed and built in the 1970s by German glider club members and intended to be suitable for training, competition and in particular aerobatics. Only one was completed. ==Design and development== Design of the LCF II began in 1971, at the beginning of a decade that saw increasing interest in aerobatic glider flight.The intention was to produce a general purpose club glider, capable of being used as a trainer or in standard gliding competitions but also to able to take the stresses involved in aerobatics.〔〔 The manoeuvrability required for the latter requires the ability to fly slowly and to rotate rapidly, calling for relatively short spans. The LCF II has a span of 13 m (42 ft 8 in).〔 The straight tapered, square tipped wings of the LCF II are mounted at shoulder height and built around a single wooden spar. The ribs are formed from polyvinyl chloride rigid foam and the wings plywood covered. The wing mounts Schempp-Hirth type airbrakes, which extend from the upper surfaces.〔 The fuselage of the LCF II is built around a steel tube structure, covered by glassfibre in front and fabric covered aft, producing a tapering hexagonal cross section from the leading edge rearwards. A long, single piece canopy extends back almost to the leading edge, where it blends smoothly into the upper fuselage line. At the rear the tailplane is attached to the top of the fuselage; the vertical surfaces are straight tapered and square tipped. All rear surfaces are foam filled and ply covered. The LFC II has a fixed monowheel undercarriage, partly recessed into the fuselage, and a tailwheel.〔 It took five air club members about 4,000 hours to build the LCF II, which made its first flight on 22 March 1975.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「LCF II」の詳細全文を読む スポンサード リンク
