Summary

Importance of the wind tunnel in the development of airplanes, from the 1903 Wright Flyer to our most advanced airplanes. Scaling parameters (Mach, Reynolds numbers). How to solve the problem of low Reynolds number. Discussion on the cryogenic solution, a way to increase the Reynolds number: effect of temperature on gas properties, test conditions and drive power and its consequences for tunnel operation. Brief history and listing of the specifications of the world cryogenic tunnels. The near future: the European Transonic Windtunnel, in Köln, Germany, will become operational in mid-1994. Discussion on the heavy-gas option, another way to increase the Reynolds number: use of R12, advantages of using binary mixtures of heavy gases. J.V.
