Reference bores are selected in blade extender and one or more reference plates are provided at a height (h1; h2) from extender flange. A reference laser device is provided within reference bores which beam impinging on reference plates is in line with bore axis. A blade root bore is selected and a laser device is fitted therein such that a measuring laser beam impinging on plates is in line with axis of blade root bore. The measuring laser beam can be then assessed. A measuring tool is used having a first end to which laser devices can be attached or other devices such as a comparator, and a movable second end for being inserted within the corresponding bores with a tight fit.
A method for determining defects in a wind turbine blade root attachment, the blade root attachment comprising a number of blade root bores formed in a blade root portion and a number of reference bores formed in a blade extender or a hub, the blade root and reference bores being suitable for receiving attaching studs therein for attaching the blade root portion (100) to the blade extender or hub, the method comprising the steps of:
The method of claim wherein at least two reference plates are provided at different heights (h1, h2) respectively from one end of the blade extender and wherein the laser assessing step includes determining an equation of a line corresponding to the measuring laser beam.
A measuring tool for determining defects in a wind turbine blade root attachment comprising a stem having a first end and a second end, said second end being suitable for being inserted within a blade root or reference bore wherein the second end of the stem includes an adjustable portion suitable for being moved relative to the first end when inserted into the blade root or reference bore such that a tight fit of the tool is created against inside of the blade root or reference bore.
