Wind turbine rotor

Wind power plant rotor comprising

• a rotor shaft;
• two or more rotor blades attached to said rotor shaft, wherein each rotor blade is comprised of a first radially inward portion and a second radially outward portion;
• rotor stiffening elements to stiffen the wind power plant rotor;
• connection devices connecting the rotor stiffening elements with each other and the rotor blades;
• and
• blade stiffening elements and a corresponding spacing element associated with each rotor blade and configured to stiffen the associated rotor blade against bending deflections;
• wherein the rotor stiffening elements and blade stiffening elements are configured to permit rotation of the rotor blades around their longitudinal axes relative to the rotor stiffening elements.
• wherein said spacing element extends from the associated rotor blade, at a radial location between said first and second portions, and said blade stiffening elements comprise:
• a first radial blade stiffening element extending from said first portion of the associated rotor blade, to a portion of the spacing element spaced apart from the associated rotor blade;
• and
• a second radial blade stiffening element extending from a second portion of the associated rotor blade to a portion of the spacing element spaced apart from the associated rotor blade.
