AERODYNAMIC PROFILE FOR THE ROOT OF A WIND TURBINE BLADE HAVING A DOUBLE LEADING EDGE |
摘要 |
<p>The invention relates to an aerodynamic profile for the root of a wind turbine blade having a double leading edge, including a leading edge (13), a trailing edge (15) and suction and pressure sides (17, 19) between the leading edge (13) and the trailing edge (15). The profile (5, 5', 5") has a relative thickness in the 30%-50% range in at least one section (37) of the root region (31). In addition, the convex portion (21) of the pressure side (19) is configured such that the curvature thereof decreases from a value C0 at the leading edge (13) to a value C1 at a first point P1 and subsequently increases to a value C2 at a second point P2, after which it decreases to a value 0 at the end of the convex portion (21).</p> |
