Abstract
A method of manufacturing a compressor. A member is cast having forward and aft annular portions. A cavity forward wall extends from the forward annular portion to a first inner end. A cavity aft wall extends from the aft annular portion to a second inner end. A cavity outer wall extends between the forward and aft annular portions and defines an outer aperture. A cavity inner wall is cast and welded between the cavity forward and aft walls such that the cavity inner wall is offset from the first and second inner ends of the cavity forward and aft walls to form a U-shaped end channel. The compressor case is capable of receiving a vane so that a trunnion bearing extends from a vane root to a trunnion bearing outer end, through the inner aperture in the cavity inner wall and the outer aperture in the cavity outer wall.
