WIND TURBINE BLADE HAVING A GEOMETRIC SWEEP |
摘要 |
<p>A swept wind turbine blade (20) includes a blade body (24) extending along a length between a root (26) and a tip (28) of the blade (20). A pitch axis (36) extends through the root (26) of the blade (20). A reference line (48) defines a deviation from the pitch axis (36) and corresponds to a swept shape of the blade (20) along its length. The reference line (48) has a zero sweep at the root (26) a zero slope at the root (26) and a positive curvature (66) along a segment within 25% of the length from the root (26) to the tip (28) of the blade (20).</p> |
