摘要：

The aeroelastic response of curved (i. e. , tip sweep in planform) wind turbine blades is analyzed. Numerical results for a 3-bladed, 20-ft radius wind turbine with fiberglass blades were obtained for various tip sweeps. Tip sweeps up to 5 ft appear to provide little tip deflection and bending moment reductions in response to gusts. However, blades with much lower torsional rigidities than the fiberglass blades were shown to provide up to 27% in tip deflections and bending moment relief during gusts.
