The flight test phase of the NASA/Army UH-60A Airloads Program was completed in February 1994. The focus of the project was to measure the airloads in flight and to this purpose 221 pressure transducers were installed in nine radial arrays; plus an additional 21 transducers along the blade leading edge to better identify blade-vortex interaction phenomena. This paper briefly describes the program's background and history, instrumentation, data acquisition and processing. The database and access tools available are discussed to provide users an understanding of the capabilities for viewing the data. Data quality is examined using several different validation techniques and sample results are presented for level flight, maneuvers, and dynamic response conditions flown. A catalog of all airloads flights is included. Over 900 flight conditions were tested and half of the data have been installed in an electronic database that is accessible to industry, academia, and other government organizations. When the database is complete it will include approximately 40-60 Gigabytes of flight data.
