Over the past 30 years, leading experts in turbomachinery unsteady aerodynamics, aer- coustics, and aeroelasticity from around the world have gathered to present and discuss recent advancements in the ?eld. The ?rst International Symposium on Unsteady Aero- namics, Aeroacoustics, and Aeroelasticity of Turbomachines (ISUAAAT) was held in Paris, France in 1976. Since then, the symposium has been held in Lausanne, Switzerland (1980), Cambridge, England (1984), Aachen, Germany (1987), Beijing, China (1989), Notre Dame, Indiana(1991),Fukuoka,Japan(1994),Stockholm,Sweden(1997),andLyon,France(2000). The Tenth ISUAAAT was held September 7-11, 2003 at Duke University in Durham, North Carolina. This volume contains an archival record of the papers presented at that meeting. The ISUAAAT, held roughly every three years, is the premier meeting of specialists in turbomachinery aeroelasticity and unsteady aerodynamics. The Tenth ISUAAAT, like its predecessors, provided a forum for the presentation of leading-edge work in turbomachinery aeromechanics and aeroacoustics of turbomachinery.Not surprisingly, with the continued development of both computer algorithms and computer hardware, the meeting featured a number of papers detailing computational methods for predicting unsteady ?ows and the resulting aerodynamics loads. In addition, a number of papers describing interesting and very useful experimental studies were presented. In all, 44 papers from the meeting are published in this volume.
