<p>The wind turbine rotor blade has a support framework (1) secured to a rotor shaft via a rotor blade carrier pipe (3) and enclosed by an outer envelope (27) formed from a high-strength flexible air-tight material, the inner space within the outer envelope defining a drive profile. The outer envelope may be shrunk-fit around the outer contour of the support framework and the interior of the envelope can be filled with a hardened foam material.</p> |
