Air foil configuration for wind turbine

摘要

A balancing of aerodynamic optimization and structural optimization provides a family of airfoils for wind turbines. Mathematic modeling yields maximum aerodynamic criteria that are coupled with a structural analysis to modify the optimum aerodynamic design into a balanced, and optimized airfoil configuration. The resulting airfoils have substantial performance impact on GROSS ANNUAL ENERGY PRODUCTION (GAEP). The airfoil is based on the theoretical optimum aerodynamic structure modified as required to maximize structural integrity. The method for maximizing airfoil performance permits the design of airfoils of predictable performance while achieving necessary structural integrity. The family of airfoils having operational and structural characteristics includes thickness-to-chord ratios ranging from 14% to 45%, a design lift coefficient in the range of 1.10-1.25 and a design Reynolds number in the range of 3 million to 8 million.
