In the past, comprehensive investigations have been made by the automobile industry and government institutions to develop new radiator fans of different geometry which generate lower noise and lower aerodynamic loss. These efforts have been conducted promarily in an empirical manner. More controlled and effective approaches are possible using modern computational methods to be described during this presentation. As a first step in the evolution of such modern analysis, an Aeroacoustic Singularity Method combined with an Optimization Code was developed at the Institute of Design Aerodynamics. This permitted conducting a research study supported by the AEG company, Germany, to improve conventional car radiator fans. In the case of periodic signals, the singularity method employs a lifting surface approach for both aerodynamics and acoustics. In the case of random signals, the method uses a semi-empirical.
