Luftwaffe Dreieckrechner DR2 Flight computer

In addition to mechanical and electrical radio directional navigation aids the Luftwaffe also utilized two different models of manual flight navigation devices which were basically circular slide rules to assist in navigation calculations. These were referred to by flight crew as 'Knemeyer' after the inventor Siegfried Knemeyer (5 April 1909 – 11 April 1979) who was a German aeronautical engineer, aviator and the Head of Technical Development at the Reich Ministry of Aviation during World War II. The earliest examples date from around June 1936 with the latest being dated November 1942.

This example is in good issued condition made by DENNERT & PAPE in Hamburg, Germany on April 1941 and carries Fl no 23825. The metal edges to the instrument show minor rubbing to the original paint finish as is to be expected. Both top and bottom dials show signs of service use but everything operates as intended and would sit happily in a Luftwaffe or general aviation collection. Measures 6" diameter (15 cm)
