Abstract
The present invention discloses a spring clip made of a directionally solidified nickel-base superalloy for use in a high pressure compressor stator sub-assembly of a gas turbine engine. The spring clip includes a body section and a pair of arms integrally connected to opposing sides of the body section and the spring clip is used as a means for attaching circumferentially segmented flowpath liners to an annular casing. Each arm of the spring clips exerts a spring force against a flowpath liner mount lug causing the mount lug to be seated radially against an inner surface of the casing and axially against an annular seal, wherein the pair of arms of each spring clip engage mount lugs located on circumferentially adjacent ones of the flowpath liners. The spring clip material has a relatively low modulus of elasticity in a direction which is generally parallel to a longitudinal axis of the spring clip, and to the base surface of the spring clip arms, and a relatively high modulus of elasticity in a direction which is parallel to the centerlines of the holes used to fixedly connect the body sections of the spring clips to the casing. Accordingly, the spring clip of the present invention has a smaller size and reduced weight, as compared to a clip made of a conventional equiax nickel-base superalloy, with no loss in preload capability of the fasteners used to attach the body sections of the clips to the casing.
