- W2321774429 abstract "One of the most persistent problems affecting the aerodynamic performance of rotorcrafts is retreating blade stall. The sudden loss of capacity to generate lift by the retreating blade results in large pitching moments on the flight control system and a net rolling moment due to the force imbalance between the advancing and retreating blades. A study of advanced airfoil sections by McCroskey 1 showed that airfoil shape can have a profound effect on the onset of stall and the lift cycle hysteresis. In this paper we apply an unsteady design optimization framework to refine rotorcraft blade designs by delaying the onset of stall, and improve aerodynamic performance as well as lift cycle hysteresis. The unsteady optimization framework utilizes an evolutionary algorithm, automated shape parameterization/deformation tool and a novel CFD derived analysis methodology for evaluating the objective function. The unsteady design optimization framework has previously been applied to shape optimization problems 2 involving pitching airfoils without dynamic stall. In this paper we extend the framework to carry out design studies of pitching airfoils in a regime where stall is prevalent. Furthermore, the data in the design landscape is analyzed with the help of Self-Organizing Maps (SOMs) to identify rules that help in generating shapes where the onset of stall has been delayed." @default.
