The Schempp-Hirth SHK is a single-seat glider made of wood.
With the cooperation of Klaus Holighaus , Schempp-Hirth turned the Standard Austria S into a new type with a larger performance range and very good flight characteristics, the SHK . The performance was mainly achieved by increasing the span to 17 m (while maintaining the Eppler E266 profile ) and thus improving the aspect ratioachieved by 21% to 20.2. In addition, the aileron differentiation was changed to 1: 3 and the ailerons were lengthened outwards in accordance with the span expansion so that they reached over 55 percent of the span. The opening angle of the V-tail was changed from 100 ° to 92 ° and the tail was enlarged a little. The SHK went into series production in 1965 and proved itself in the same year at the Gliding World Championships in South Cerney (England): Seff Kunz came third in the Open Class behind an SZD-24-4 Foka 4 and the Akaflieg Darmstadt D-36 . Further successes followed in 1966 with second place in the German championship and victory in the national championships in England, Italy and Switzerland. Probably the last appearance of a SHK in an international competition was the 9th place of Klaus Ohlmann at the European championship of the club class 1990 in Denmark.
When the plastics era began with the Cirrus at Schempp-Hirth in Kirchheim / Teck in 1968 , production was discontinued after 59 aircraft. The successor to Standard Austria was the Standard Cirrus . The SHK is one of the best wooden gliders in terms of surface quality.
