Airfoil section for complex geometric shaped rotor blade of wind turbine, has leading edge including flexible outer layer and extended with adjusting unit to ensure adjustment of outer contour of leading edge

摘要

The section (1) has a leading edge (6) including a flexible outer layer and extended with an adjusting unit to ensure adjustment of an outer contour of the leading edge. The adjusting unit includes a pressure piece that is attached to an inner side of the leading edge. The pressure piece extends along a surface of inner side of the leading edge such that multiple areas of inner side of the leading edge accomplish a relative motion of the pressure plate. A printing unit includes a compression spring and a guide cylinder in which a piston is guided.
