Cryogenic Wind Tunnelsmic testing experience in the NASA Langley 0.3-m Transonic Cryogenic Tunnel (TCT). Since we built the 0.3-m TCT in 1973, it has logged over 8000 hours of running at cryogenic temperatures. We use the 0.3-m TCT for aerodynamic testing and to develop test techniques for cryogenic tunnels..Areas briefl

High-Reynolds-Number Test Requirements in Low-Speed Aerodynamicske a major contribution. Research areas discussed include high-Reynolds-number experimental requirements for: (a) wake vortex hazard, physics and alleviation (control of vortices) (b) supermaneuverability via body vortex control (control by vortices), and (c) high-lift device development and evaluat

Flow Visualizationapplicable to liquid helium flows. Focusing schlieren, particle image velocimetry, and holocinematography are described in some detail. The last of these in particular can give the time-varying three-dimensional velocity field.

On the Measurement of Subsonic Flow around an Appended Body of Revolution at Cryogenic Conditions ins discussed. Some pertinent details of the “1986 Body of Revolution Experiment” are presented along with possibilities for a “Future Body of Revolution Experiment” and a “Future Rat Plate Experiment”. Finally NTF testing is considered from the “hydrodynamic” users point of view and a brief compariso
