摘要：
The lift and drag coefficients of airfoils, used in wind turbine blades, are measured by wind tunnel tests. Large uncertainties are possible due to experimental errors and wind tunnel laboratory variability. Uncertainties in the aerodynamic loads have an important effect on the structural reliability of wind turbine blades. In this paper, the aleatory behaviors of the aerodynamic loads for a three-dimensional wind turbine blade are investigated by wind tunnel tests. Different angles of attack and Reynolds numbers are considered to quantify the uncertainties in the lift coefficients.
