Rotor blade
摘要:
A rotor blade for a turbine engine including a blade root section and an airfoil section which extends radially outward along a radial line RAS from the blade root section, is described. The radial line RAS extends at an angle relative to a plane extending across a top surface of the platform, rather than normal, or perpendicular, to such plane. As a result, and during a blade out event, an over turning moment is generated in a root of the airfoil section. The overturning moment facilitates bending the airfoil section reducing damage to the stator.
