다국어 초록 (Multilingual Abstract)

The designofhorizontalaxiswindturbine(HAWT)bladesinvolvesseveralgeometriccomplexities.Asaresult,themodelingofthesebladesby commercialcomputer-aideddesign(CAD)softwareisnoteasilyaccomplished.Inthepresentpaper,theHAWTbladeisdividedintostructural andaerodynamicsurfaceswitha G1 continuity imposedontheirconnectingregion.Thewidelyusedmethodofskinningisemployedthroughout thecurrentworkforsurfaceapproximation.Inaddition,toensurethecompatibilityofsectioncurves,anovelapproachisdevelopedbased ontheredistributionofinputairfoilpoints.Inordertoevaluatedeviationerrors,theHausdorffmetricisused.Thefairnessofsurfacesisquantitatively assessedusingthestandardstrainenergymethod.Theabove-mentionedalgorithmsaresuccessfullyintegratedintoaMATLABprogram soastoenhancefurtheroptimizationapplications.The final surfacescreatedbytheproceduredevelopedduringthepresentstudycanbeexported usingtheIGESstandard file formatanddirectlyinterpretedbycommercialCADandFEsoftware.
