Dietrich Küchemann CBE FRS[1] FRAeS (11 September 1911 – 23 February 1976)[2] was a German aerodynamicist who made several important contributions to the advancement of high-speed flight.
During this period he continued research, notably into the problems of high speed flight, wave drag, swept wing theory and initial steps on the road to the area rule, and he designed a fuselage shape later dubbed the "Küchemann Coke Bottle".
He retired from administrative duties in 1971, but continued work on an effort to build a very large supersonic wind tunnel for use by various European research departments, but this was not completed in his lifetime.
He was awarded the Ludwig-Prandtl-Ring from the Deutsche Gesellschaft für Luft- und Raumfahrt (German Society for Aeronautics and Astronautics) for "outstanding contribution in the field of aerospace engineering" in 1970.
His name has entered aeronautical lore in the form of the trailing edge anti-shock bodies used on the Handley Page Victor bomber, commonly referred to as "Küchemann carrots".
