03.1 - Aerodynamics CFD Methods and ValidationPROPELLER AEROACOUSTIC MODELS IN VARIABLE-FIDELITY DESIGN OPTIMIZATIONW. Klimczyk¹, A. Sieradzki¹; ¹Lukasiewicz Research Network - Institute of Aviation, Poland Current work provides a summary of crucial aspects in defining the propeller aeroacoustic optimization framework. It is focused on: defining the design process framework and selection of suitable aeroacoustic models. The advantages and limitations of using various models are discussed. The potential of merging data from models of various fidelities to speed up the optimization process is assessed. |
