ABSTRACT:
A mounting assembly for supporting stator vane platforms formed in an extended arc length, in a compressor casing, comprising a circumferential flange formed in the compressor casing having spaced clamp arms, a flange carrier on each stator vane platform having a surface which is formed with a plurality of radially outwardly extending wedge lock elements, and locking springs having inner and outer sides each formed with wedge lock elements extending radially outwardly therefrom. In order to mount the stator vane platform on the compressor casing, the locking springs are placed in an "unlocked" position on the flange of a stator vane platform wherein the wedge lock elements on the inner side of the locking spring extend between adjacent wedge lock elements on the flange. The vane platform flange and locking spring are then inserted as a unit between the clamp arms of the compressor casing. The locking spring is then moved to a "locked" position wherein the wedge lock elements on the inner side of the locking spring engage the wedge lock elements on the flange of the vane platform, and the wedge lock elements on the outer side of the spring engage one of the clamp arms. In the locked position, the locking spring is wedged between the vane platform flange and one of the clamp arms, and applies a radially inwardly and outwardly directed force thereto which securely mounts the vane platform flange between the clamp arms of the compressor casing and reduces leakage of air therebetween.
