Abstract : The aim of the symposium is to review and discuss recent developments in aerodynamics and aeroacoustics as they apply to the rotary-wing aircraft, and to foster the future development of this class of flight vehicles. The Symposium recognizes the importance of understanding and accurately predicting the aerodynamic and acoustic characteristics of military and civil rotorcraft; and the need for improved phenomenological insight, better math models, adequate test equipment, and more precise and efficient numerical methods. Despite current limitations, considerable progress has been made in many technological fields in the last decade. New test facilities and test stands have been constructed, improvements in aerodynamic theory and tools have led to a better understanding of noise generation phenomena, and Computational Fluid Dynamics (CFD) and Computational AeroAcoustics (CAA) have evolved into useful techniques for designers. The agenda of the Symposium was as follows: Opening Remarks Keynote Speech Keynote Paper Session 1, Dynamic Stall Session 2, Wind Turbines Session 3, Three-Dimensional Aerodynamic Prediction Methods Session 4 and 5, Experimental Investigations on Helicopter Rotors Session 6 and 8, Acoustic Prediction Methods Session 7, Interference Problems Closing Remarks (KAR) P. 11
