Hans Zacher (born November 22, 1912 in Lüdenscheid ; † August 5, 2003 in Gauting ) was the developer of the standard for determining flight characteristics .

Life

Hans Zacher was born in Lüdenscheid, where he attended school and graduated from high school. He then did an apprenticeship as a locksmith, began studying at the TH Darmstadt in 1933 and joined the Darmstadt technical department . After completing his studies, he joined the German Research Institute for Glider Flight as a graduate engineer , where he was head of department until the end of the war. In 1944 he wrote a report on the "flight suitability test" of the D-30 Cirrus glider .

After the Germans were allowed to fly again, Hans Zacher became a type examiner for aircraft. Soon, however, he returned to the research institute from which the DLR later developed.

Hans Zacher brought many ideas into gliding, some of which were groundbreaking. His greatest merit is a protocol for measuring flight characteristics, which includes various flight maneuvers to be carried out to record sliding roll moments, curve change times, longitudinal stability and much more. Zacher not only thought up and carried out these maneuvers, but made them standard. The properties shown during these maneuvers are measured with the so-called "Zacherbesteck". These include a stopwatch, a spring balance and the phipsitheta, with which you can read angles in different flight positions. In this way, different aircraft are examined at the annual Idaflieg meeting in Elchingen . The zacher is the easiest way to determine how a glider can be handled on the fly.

Hans Zacher was an honorary member of the OSTIV (Organization Scientifique et Technique du Vol à Voile), holder of the Tissandier Diploma - which is awarded for outstanding achievements in the field of recreational aviation - and a specialist book author.
