Abstract
A stator vane assembly for a gas turbine engine, the stator vane including an airfoil portion formed from a single crystal material and two platforms attached to the ends of the airfoil by shear pins that fit within slots formed between the platform and airfoil. The shear pin slots extend along the contour of the airfoil where the lowest stress levels are located. The platforms include openings having the same cross sectional shape as the curved airfoil. Because of the shear pin retainers between the airfoil and the platforms, the airfoil can be formed from a single crystal material while the platforms are un-coupled from the airfoil and can be made from a different material.
