In 1975 the U.S. Air Force and the Federal Republic of Germany signed a Data Exchange Agreement numbered AF-75-G-7440 entitled 'Viscous and Interacting Flow Fields.' The purpose was to exchange data in the area of boundary layer research. It includes both experimental and theoretical boundary layer research at speeds from subsonic to hypersonic Mach numbers in the presence of laminar, transitional, and turbulent boundary layers. The main effort in recent years has been on turbulent boundary layers, both attached and separated in the presence of such parameters as pressure gradients, wall temperature, surface roughness, etc. In the United States the research was conducted in various Department of Defense, NASA, aircraft corporations, and various university laboratories. In the Federal Republic of Germany it was carried out within the various DFVLR, industrial, and university research centers.

In September 1968, the FDP of AGARD held a specialists' meeting in Paris on transonic aerodynamics, in recognition of the fact that the absence of adequate theoretical methods and wind-tunnels of high enough Reynolds number had already led to costly shortcomings in the transonic performance of certain combat and transport aircraft. Since projected aerospace systems, military, civil and space-oriented, would involve flight at Reynolds number of up to 100 million, the FDP undertook an examination of the requirements of NATO nations for wind tunnel facilities for testing large models at high Reynolds numbers.
