AIAA-2000-1770AN OVERVIEW OF UNSTEADY PRESSURE MEASUREMENTS IN THETRANSONIC DYNAMICS TUNNELDavid M. Schuster*, John W. Edwards*, and Robert M. Bennett*NASA Langley Research Center, Hampton, VA 23681-2199AbstractThe NASA Langley Transonic Dynamics Tunnel has served as a unique national facility foraeroelastic testing for over forty years. A significant portion of this testing has been to measureunsteady pressures on models undergoing flutter, forced oscillations, or buffet. These tests haveranged from early launch vehicle buffet to flutter of a generic high-speed transport. This paper willhighlight some of the test techniques, model design approaches, and the many unsteady pressuretests conducted in the TDT. The objectives and results of the data acquired during these tests willbe summarized for each case and a brief discussion of ongoing research involving unsteadypressurc measurements and new TDT capabilities will be presented.INTRODUCTIONA wide variety of tests have been conducted in theNASA Langley Transonic Dynamics over the last fortyyears. The tests have encompassed flutter clearance _,
