Abstract
A wind turbine blade having a longitudinal axis is provided. The wind turbine blade includes a root portion and a tip portion. The root portion has a supported end and an unsupported end. The tip portion is configured to be slidably received within the unsupported end of the root portion. A transverse gap is defined between the root portion and the tip portion. A transition element is affixed to the unsupported end of the root portion such that the transition element at least partially bridges the transverse gap. The wind turbine blade may further include blade cleaning elements and/or sensing elements, particularly in the vicinity of the transition element.
