Abstract: A method of positioning a wind turbine rotor comprises defining a predetermined angular position in a main rotation plane of the rotor and controlling a rate of deceleration of the rotor, such as to stop the rotor at the predetermined angular position.

Abstract: A prefabricated half-product for use in manufacture of a fiber-reinforced composite part of a wind turbine is provided, the half-product comprising at least one fiber mat and at least one inlay which is attached to the at least one fiber mat such that the relative position of the at least one inlay with respect to the at least one fiber mat remains substantially fixed during the manufacture of the fiber-reinforced composite part of the wind turbine. Furthermore, a method for manufacturing the half-product and method for the use of the half-product are provided.
