Abstract : The need for a large High-Reynolds-Number Transonic Wind Tunnel has long been recognized throughout the industry, both in the USA and Europe. Such a facility will provide a much needed tool for studying phenomena sensitive to Reynolds number. The National Transonic Facility (NTF), located at NASA Langley Research Center, is now in the calibration phase and has the desired capability. Its usefulness, however, will be greatly influenced by the ability of industry to develop model systems capable of withstanding the severe operating environment of the facility so necessary to achieve full-scale Reynolds number, without degradation of accuracy, and at reasonable cost. The basic objective of this engineering study was to determine the feasibility of designing models of advanced aerodynamic technology does offer the potential for making tunnel-to-full-scale data correlations for this type of aircraft configuration.
