TECHNICAL ABSTRACT ( Limit 2000 characters, approximately 200 words)
With increased commercial competition, great pressure is being applied to effect aerodynamic design changes that will improve fuel economy and performance. But, for example, as we are now concerned with small changes in drag count, potential sources of improvement are much more likely to be masked by poor flow quality. We may have reached the stage where the lack of suitable facility flow quality will hinder and dictate the rate of progress of ground based testing. Few measurements have been made in the Nation's wind tunnels, and in those cases, large discrepancies have been found between full-scale and predicted performance. Consequently, there is an urgent need for in-situ measurements to measure flow quality and the performance of turbulence and noise suppression devices. To meet these challenges, a unique research program is proposed to clarify and alleviate the aerodynamic problems associated with adverse wind tunnel flow quality. It combines innovative advances in data base assessment and management, and new approaches to turbulence instrumentation and analysis. Standardized turbulence measurement techniques and data analysis procedures will be established and used to document the flow quality in our major test facilities.

POTENTIAL NASA COMMERCIAL APPLICATIONS ( Limit 1500 characters, approximately 150 words)
There is a national need to develop improved test capabilities for proposed civil and military aerospace systems. Detailed flow quality measurements and assessments of the performance of turbulence and noise suppression devices will lead to cost effective improvements in wind tunnel flow quality which will be needed to help design and ground test the proposed new generation of fuel efficient commercial transports and advanced military aircraft proposed for the new millennium. Standardized test procedures will enable meaningful assessments to be made of individual tunnel operational ranges with adequate flow quality related to specific test programs. These advances will help provide NASA with superior test capabilities at competitive cost and so attract a viable customer base that will be required for cost-effective facility operations.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS ( Limit 1500 characters, approximately 150 words)
Measurements are urgently needed in the Nation's major facilities if we are to successfully combat the ever increasing European test facility challenge. Wind tunnel disturbances must be measured to the highest accuracy to allow the aerodynamicist to distinguish between aerodynamic, aeroelastic, and Reynolds number effects. Measurements will help provide U.S. companies with superior test capabilities at competitive cost and so help attract a viable customer testing base that will be required for cost effective facility operations. This state-of-the-art turbulence testing capability available to support commercial aerospace needs meets two of the three main goals of NASA's Aeronautics Test Program (ATP) for corporate management of Aeronautical facilities namely: to "increase the probability of having the right facilities in place at the right time" and to "operate those facilities in the most effective and efficient manner."

NASA's technology taxonomy has been developed by the SBIR-STTR program to disseminate awareness of proposed and awarded R/R&D in the agency. It is a listing of over 100 technologies, sorted into broad categories, of interest to NASA.
