  • Wind turbine blade provided with root end flange
    Patent number: 11428202
    Abstract: A wind turbine blade (10) for a horizontal axis wind turbine (2), wherein the wind turbine blade (10) extends in a longitudinal direction parallel to a longitudinal axis and having a tip end (14) and a root end (16), and wherein the wind turbine blade (2) further includes a shell body is disclosed. The wind turbine blade (10) further includes a root end flange (55, 155, 255) at the root end (16) of the blade (10) and which includes a ring-shaped body that extends circumferentially along the entire root end (16), the root end flange (55, 155, 255) preferably made from a metal, such as stainless steel. The root end flange (55, 155, 255) includes an inwardly extending protrusion (70, 170) with a distal plate part (72, 172, 272, 372, 472, 572, 672, 772) arranged in a distance from the ring body.
