MECHANICAL INTERLOCK FOR MULTI-MATERIAL AIRFOIL

摘要

PROBLEM TO BE SOLVED: To provide a mechanical interlock for a multi-material airfoil.SOLUTION: A mechanical interlock includes: a first airfoil portion (34) which can be connected to a rotor disk (32); and a second airfoil portion (36) connected to an interlock feature of the first airfoil portion. The first airfoil portion is formed with a first material and can have the interlock feature (52) extended therefrom. The second airfoil portion radially extends from the first air foil portion, and can be formed with at least partially different materials.
