Abstract
An aerofoil has a tip section formed at least in part of composite structure wherein a substantial number of fibres are skew to the spanwise direction, resulting in the direction of principal bending stiffness of the aerofoil being diverted away from the spanwise direction in said tip section to induce twist under certain loading conditions.
Claims3
An aerofoil having a direction of principal bending stiffness extending substantially spanwise, said aerofoil comprising a tip section formed at least in part of composite structure in which a plurality of fibres extend generally parallel to a spanwise axis of said areofoil and wherein a substantial number of said fibres terminate at said tip section in positions skewed to the spanwise direction such that the direction of principal bending stiffness is diverted away from the spanwise direction in said tip section towards an edge of the aerofoil.
