Bonded window cover with joint assembly for a wind turbine rotor blade

Abstract:

A bonded window cover for an access window of a rotor blade assembly having a unique joint assembly is provided. For example, for rotor blade assembly having blade inserts that form access windows with the rotor blade segments, the laminated in window covers are replaced with bonded windows. More specifically, the bonded-in window covers are bonded in with a window frame lap joint, which allows the transition from two sets of inner skin layers (bonded onto one another) to one set of inner skin layers. Without this transition, the leading edge would have an undesirable bump or protrusion as well as waves in the skin layers.
