Integrated Optimum Design Approach for High Speed Prop-Rotors Including Acoustic

摘要

The objective of this research is to develop optimization procedures to providedesign trends in high speed prop-rotors. The necessary disciplinary couplings are all considered within a closed loop multilevel decomposition optimization process. The procedures involve the consideration of blade-aeroelastic aerodynamic performance, structural-dynamic design requirements, and acoustics. Further, since the design involves consideration of several different objective functions, multiobjective function formulation techniques are developed.
