Luftfahrtforschungsanstalt

Luftfahrtforschungsanstalt (Aeronautical Research Institute, LFA, also known as the Hermann Göring Research Institute) was a secret German facility for airframe, aeroengine, and aircraft weapons testing during the Second World War. It was Germany's "most advanced and extensive [aviation] research establishment, outside of the existing Erprobungsstelle network of military aviation evaluation facilities, themselves headquartered at Rechlin.

Located near Völkenrode, on the western outskirts of Braunschweig (Brunswick), near what became the Inner German Border. it was a 1,000-acre (400 ha) site begun in October 1935. The first wind tunnel was begun in November 1936. Most of the sixty buildings, scattered around the site, did not exceed treetop height, and all were well-camouflaged, to reduce the chance of them being detected by aerial reconnaissance and to avoid making them targets, as the wind tunnels of the Deutsche Versuchsanstalt für Luftfahrt (DVL) in Adlershof (near Berlin) or the (AVA, part of today's DLR agency) at the University of Göttingen were.

The buildings were in five groups. The Institute of Aerodynamics had five wind tunnels, while the Institute of Gas Dynamics had its own high-speed tunnel; both were at the southern end of the campus. The static testing station of the Institute of Strength Properties was to the west; the Institute of Engine Research, the east. Weapons research was done by the Institute of Kinematics in a 400 m (1,300 ft)-long tunnel in the northwest corner. These were accompanied by administration buildings, a canteen, a telephone exchange, guard houses, generators, and other facilities.
