摘要： A method for creating a transition from an edge of an add-on part mounted on the outer surface of a rotor blade, including the steps: delimiting an application area on the rotor blade surface and the add-on part to be covered by a sealant compound with a thin and smooth masking tape; dispensing of the sealant on the application area; distribution of the sealant; removing the masking tape; and smoothening of a sealant transition step with a flexible tool, is provided. A wind turbine rotor blade is also provided.

摘要： An assembly for monitoring air flow at a surface of a rotor blade of a wind turbine is provided. The assembly includes (a) a surface module adapted to be arranged at a predetermined location of the rotor blade surface, the surface module including two air inlets facing opposite directions along an axis, (b) a sensor module including two pressure sensors, wherein one of the two pressure sensors is in fluidic communication with one of the two air inlets and the other one of the two pressure sensors is in fluidic communication with the other one of the two air inlets, wherein the sensor module is adapted to output two pressure signals indicative of the pressures sensed by the two pressure sensors, and (c) a processing unit adapted to determine at least one of a flow direction and a flow speed along the axis based on the two pressure signals.

摘要： A method of providing an edge seal along a longitudinal edge of an add-on part mounted on the outer surface of a rotor blade is provided. The method includes determining a height at the longitudinal edge of the add-on part, choosing a width for the edge seal to be applied on the rotor blade surface, wherein the width of the edge seal is chosen to exceed the height at the longitudinal edge of the add-on part by a factor of at least twenty; and forming the edge seal by applying a sealant material to the rotor blade surface at least in a volume defined by the height at the longitudinal edge of the add-on part and the chosen edge seal width.
