(54) TRAILING EDGE ASSEMBLY


(57) The invention describes a wind turbine rotor blade (2) comprising a root end (2R), an airfoil (2A), and a transition region (2SC) extending between the root end (2R) and the airfoil (2A), further comprising a chord-adjustable trailing edge assembly (1) extending over at least a portion of the transition region (2SC), which chord-adjustable trailing edge assembly (1) comprises an inflatable support structure (10); a flexible material (11) arranged to cover the inflatable support structure (10); and an interface (135) to a volume control means (13) realised to adjust the volume of the inflatable support structure (10) to extend a chord length (Cext) of the transition region (2SC).
