Analysis on the influence of aerodynamic performance enlarging the airfoil trailing edge thickness

Journal Article


Abstract


  • The FFA-W3 series airfoil trailing edge thickness is enlarged. The modified and pre-modified airfoil aerodynamic performance was calculated by using the analysis and design software for low Reynolds numbers airfoils XFOIL. The angles of attack for airfoil performance data is extended to 90 degree by using Viterna-Corrigan post-stall model. A comparison analysis of the aerodynamic performance data between the modified and pre-modified airfoils was performed. Using the aerodynamic performance data of the modified and pre-modified airfoils, the aerodynamic performance of a 600 kW wind turbine was calculated. The calculation results showed that the influence of aerodynamic performance is little as enlarging the airfoil trailing edge thickness. The conclusion can be made that enlarging the airfoil trailing edge thickness to meet the technological conditions is a feasible solution.
