Xaver Hafer (born October 6, 1915 in Hanover ; † September 30, 2003 ) was a German aerospace engineer .

Life

He spent childhood and school in his hometown of Hanover. After completing a degree in aircraft construction at the Technical University of Hanover, he joined the development department of the Heinkel company in Rostock on June 1, 1939 . During this time, Xaver Hafer worked with the aerospace engineers Siegfried Günter and Karl Schwärzler , who shaped his way of thinking and working as an engineer. In 1942 he moved to the development department of the Heinkel company in Vienna , where he worked on the development of the Volksjäger He 162 .

In 1954, Hafer joined the new Heinkel company and was instrumental in the reconstruction of the German aviation industry in the following years. In 1957 he received his doctorate from the Technical University of Braunschweig under Professor Schlichting.

On May 1, 1966, Prof. Dr.-Ing. Xaver Hafer took over the chair of aviation technology at the University of Darmstadt . He worked with the research focus on flight mechanics and aerodynamics and in a special field in which he made a name for himself as a pioneer, namely the problem of steep and vertical take off aircraft.

His books Flight Mechanics and Flight Performance (with Gerhard Brüning), Vertical Takeoff Technology and Flight Mechanics: Modern Airplane and Control Concepts (with Günter Sachs) are considered standard works.
