Abstract
A method of producing a wind turbine rotor blade. The wind turbine rotor blade has at least an inner blade portion and an outer blade portion, as well as a connecting element. The inner blade portion is wound on a winding form having a first and a second winding portion. The first and second winding portions are releasably fixed to each other by way of a screw connection. The second winding portion is of a conical configuration so that after winding of the inner blade portion a sleeve is produced at an end of the inner blade portion.
Claims3
A method of producing a wind turbine rotor blade comprising an inner blade portion and an outer blade portion, the method comprising:
- forming the inner blade portion by winding composite fabrics on a first winding form, the first winding form having a first winding portion configured to separate from a second winding portion, wherein the first and second winding portions are fixed to each other in a longitudinal direction,
- wherein the second winding portion is of a conical configuration in the longitudinal direction so that after the winding composite fabrics, a sleeve is formed at an end of the inner blade portion, and
- winding laminate on a second winding form to form a connecting element, wherein the connecting element is configured to connect the inner blade portion and the outer blade portion together, wherein the connecting element has a first portion and a second portion, and
- wherein a form having a conical shape is pushed on to the first portion of the connecting element before the winding laminate is hardened in order to provide a first portion of a conical configuration.
