The Standard Austria is a single-seat glider made of wood.
The Austrian engineer Rüdiger Kunz designed an aircraft for the standard class in 1958 according to FAI regulations . In order to achieve optimum performance with good as well as weak thermals with reasonable construction costs, he broke new ground in the construction of Standard Austria.
In order to be able to carry out repairs without specialist workshops, the aircraft was made almost entirely of wood. Only the front part of the fuselage, the end of the fuselage and the edge arches of the wings were molded from glass fiber polyester material in a negative mold.
The wooden shell of the wings and tail units was used to absorb the forces. In order to achieve the highest accuracy, they were built in a device made of steel tubes.
14 aircraft were built in Austria, after which Schempp-Hirth acquired the license to build. After 30 built Standard Austria S was built in 1961/62 using a new laminar profile by Dr. Richard Eppler created the Standard Austria SH . By mid-1965, 60 of this further development had been built.
The V- tail and the high surface quality of the fuselage and wing are characteristic of Standard Austria , so that it is hardly recognizable that it is a wooden aircraft.
