Further improvements in cost effectiveness of wind tunnel testing at PWT

The continuing improvements in the tunnels of the Propulsion Wind Tunnel Facility at the USAF Arnold Engineering Development Center have centered on reducing the energy and manpower required to obtain data without compromising data quality reducing the quantity of data needed for decisionmaking. More efficient tunnel operations result from the automation of controls, improved procedures, improvements to components such as diffusers, reductions of manpower through consolidation and cross-training, reduction in the cost of electricity by drastic restructuring of the power contract, and by reducing the air-on time to obtain the required data. The quantity of data required has been frequently reduced by a 'near real-time' interactive graphics system for on-line decisionmaking. Further reductions have resulted from the use of CFD to predict and interpolate test data, verify and evaluate test data as it is obtained, and optimize test programs. (Author)
