<p>The blade (10) has a blade root (14), a blade tip (12), an aerodynamic profile, and a longitudinal portion (24) including the pressure side (28), suction side (26), profile nose edge (20), and a chord (18). The trailing edge (30) of the pressure side meets with the suction-side end (32). The suction-side end which is spaced apart from pressure-side end point (34), meets the pressure side and trailing edge. The angle between the chord and the trailing edge is smaller than 90[deg] . The suction-side end is arranged on profile nose edge than the end point, in the direction of chord.</p> |
