Schempp-Hirth Standard Austria
Osterreichischer Aero-Club Standard Austria

This high performance Standard Class single-seater was the result of a commission by the Austrian Aero Club (Osterreichischer Aero-Club) to Ing Rudinger Kunz to design them a sailplane in this category; the prototype first flew in July 1959, and the design duly won the OSTIV Trophy in 1960 for the best Standard Class type in the World Championships at Koln-Butzwelerhof in Germany.
 
In designing the Standard Austria Rudinger Kunz sought to combine a high lift/drag ratio and a relatively low wing loading, and the type's great strength and excellent flying characteristics made it suitable for cloud flying and spinning, although it is not aerobatic. The cantilever shoulder wings are of wooden construction and are unusual in having no spars; they are fabric-covered from the 65% chord line to the trailing edge and there are air brakes in the upper surfaces. The circular section monocoque fuselage has a glassfibre nose section, pilot's seat and rear fuselage, the centre portion being of wood. The 'butterfly' V-tail surfaces are all-moving wood and fabric structures with an included angle of 90°, and each surface has a geared tab. There is a fixed monowheel forward of the cg, with a disc brake, and a small tailwheel. The pilot sits in an adjustable seat under a blown plastic canopy, and there is provision for radio, an oxygen system and full blind-flying instrumentation.
 
14 were built in Austria before production was licensed and transferred to Schempp-Hirth in Germany in March 1962. Schempp-Hirth produced 30 Austrias and 5 improved and slightly heavier Austria SH’s.
 
The 1964 model of the type, the Standard Austria SH, had an Eppler 266 laminar flow wing section instead of the previous NACA 65(2)-415 aerofoil, giving an improved performance at lower speeds; the SH also had a retractable monowheel as an optional feature, and this version was developed into the Schempp-Hirth SHK.

In 1964 a modified version appeared with an Eppler 266 airfoil to improve low-speed performance. A retractable gear was optional (making it a SH-I), giving much improved ground clearance. The Standard Austria has an all-moving V-tail and airbrakes.
 
Standard Austrias held the world goal record of 737 km./ 458 miles and the world goal-and-return record of 698 km./ 434 miles.
