Book Description

This meeting reviewed the current status of new wind tunnel facilities and gave a perspective of recent developments in testing techniques and fluid motion problems related to wind tunnel testing. It was organized in five sessions. The session on Facilities dealt almost exclusively with cryogenic wind tunnels. The National Transonic Facility is operational and valuable experience already has been gained, not only on operational aspects but also on model design. The major European countries are putting considerable effort into the joint European Transonic Wind Tunnel. The emphasis on cryogenics was again highlighted in the session on Fluid Motion Problems, addressing such areas as condensation and nonadiabatic wall effects, as well as model test results from a cryogenic facility. Flow quality was also given prominence. That conventional wind tunnels are still the backbone of the Testing Establishment was demonstrated in the three sessions of Testing Techniques. The presentations covered a large variety of topics including support interference, dynamic testing, inlet/engine/afterbody related testing, store separation, half-model testing technique, aero-acoustic measurements and wind tunnel-flight data comparisons.
