Rudolf Kaiser

Who was Rudolf Kaiser?

Rudolf Kaiser was a designer of gliders who worked for Alexander Schleicher GmbH & Co.

The designs of Rudolf Kaiser have proven themselves for over 50 years all over the world. His designs for Schleichers can be recognised by the K in the ASK designation. The designs that he did on his own account have the designation Ka.

He was born in Coburg, Germany, and graduated in house construction in 1952. However at the same time he took up gliding. He built a small single seater, the Ka 1 at his home in 1952 to perfect his design skills. His next glider, the two-seat Ka 2, was created for Alexander Schleicher, the sailplane manufacturer in Poppenhausen. Rudolf Kaiser also worked for Egon Scheibe designing the Ka 5 "Zugvogel" which was the best performing production sailplane in the world at the time.

To get his Gold C, he again built a sailplane for himself; the Ka 6. It won the OSTIV prize for the best new design in 1958. After Schleicher put it into production, it became the most popular Standard Class sailplane, winning two World Gliding Championships. 1368 Ka 6's were built and many are still flying.
