Abstract: According to one aspect, an airfoil assembly for a gas turbine engine comprises a first end wall, a second end wall, an airfoil and a sheath. The first end wall has surfaces defining a first recess, and the second end wall has surfaces defining a second recess. The airfoil includes a first portion disposed in the first recess, a second portion disposed in the second recess, and a leading edge disposed between the first and second portions. The sheath is in contact with the first and second portions of the airfoil covering the leading edge between the surfaces defining the first and second recesses.
