Abstract: Natural laminar flow (NLF) design is widely used to reduce skin friction drag to improve aircraft aerodynamic performance. In this paper, a differential evolution (DE) algorithm was applied to a NLF-designed transonic ...

Abstract: Inlet separation is one of the primary sources of distortion at fan entrances. High angles of attack (AOAs) are the critical cause of inlet separation. Optimizing the inlet shape to increase the separation angle is of great ...

Abstract: Nacelle cowl design is dedicated to generating a three-dimensional surface with optimal drag performance. Most previous approaches focused primarily on the design method driven by streamwise profiles, which introduced no ...

Abstract: In the approach of metric-based geometric parameterization, the concept of database filtration and proper orthogonal decomposition manipulation quantitatively enhances the generation of new geometric parameters so that the ...
