Title:
ROTOR BLADE
Document Type and Number:
Japanese Patent JP2001055996
Kind Code:
A
Abstract:
To provide a rotor blade and vane for a turbine engine constructed to be easier to bend or buckle than conventional rotor blades and vanes.
A rotor blade 100 for a turbine engine has a blade root portion 104 and an aerofoil portion 102 extending radially outward from the blade root portion 104 along a radial line RAS. The radial line RAS extends slantly at an angle rather than perpendicular or transverse to a plane along the upper face of a platform 106. As a result, over-turning moment occurs at the root of the aerofoil portion 102 during blading-out. The over-turning moment facilitates the bending of the aerofoil portion 102 and reduces damage to a stator.
