RELIABILITY-BASED OPTIMIZATION OF AIRFOILS USING A MOMENT METHOD AND PARSEC FUNCTION

모멘트 기법과 PARSEC 함수를 이용한 에어포일 신뢰성 기반 최적설계

In this study, reliability-based design optimizations of airfoils were performed. PARSEC function was used to consider the uncertainty of the aerodynamic shape for the reliability-based shape optimization of airfoils. Among aerodynamic performance. The accuracy of the reliability analysis was compared with other method and it was found that the moment method predicts the probability accurately. Deterministic and reliability-based optimizations were performed for shape of the RAE2822 airfoil and it was demonstrated that reliability-based optimizations the aerodynamic performances under uncertainties of the shape of the airfoil.
