Abstract
A turbine inner shroud and a turbine assembly. The turbine assembly includes a turbine stator having a longitudinal axis and having an outer shroud block with opposing and longitudinally outward facing first and second sides having open slots. A ceramic inner shroud has longitudinally inward facing hook portions which can longitudinally and radially surround a portion of the sides of the outer shroud block. In one attachment, the hook portions are engageable with, and are positioned within, the open slots.
Claims8
A turbine assembly comprising:
- a) a turbine stator having a longitudinal axis and an outer shroud block, wherein said outer shroud block has a circumferential segment, wherein said circumferential segment has longitudinally spaced apart, generally opposing, and generally longitudinally outward facing first and second sides, and wherein said first side has a generally longitudinally outward facing first open slot;
- b) a ceramic inner shroud including a first hook portion having a first end disposed in said first open slot;
- c) a first compliant member disposed in said first open slot and surrounding said first end of said first hook portion of said ceramic inner shroud;
- and
- d) a first metal clip disposed in said first open slot and surrounding said first compliant member.
A turbine assembly comprising:
- a) a turbine stator having a longitudinal axis and an outer shroud block, wherein said outer shroud block has a circumferential segment, wherein said circumferential segment has longitudinally spaced apart, generally opposing, and generally longitudinally outward facing first and second sides, wherein said first side has a generally longitudinally outward facing first open slot, and wherein said second side has a generally longitudinally outward facing second open slot;
- b) a ceramic inner shroud including a first hook portion having a first end disposed in said first open slot and including a second hook portion having a second end disposed in said second open slot;
- and
- c) said first hook portion having a first curved region, said second hook portion having a second curved region, said first and second curved regions having longitudinally-outermost points which are longitudinally spaced apart a first longitudinal distance, and said ceramic inner shroud having a longitudinal length equal to said first longitudinal distance.
