Abstract
An exemplary embodiment of the invention is directed to a turbine engine having a circumferential casing with a circumferentially extending slot formed in an inner wall. A radially inwardly facing fin-ring is disposed in the slot and has a radially inwardly projecting fin extending axially there across. A radially inwardly extending stator blade has a base and an airfoil. The base is disposed in the casing slot, radially inwardly of the fin-ring. A complementary base slot is disposed in the stator blade base and is configured to receive the fin therein for the transfer of a circumferential force, applied to the stator blade, to the fin-ring.
Claims11
A turbine engine comprising:
- a circumferential casing having a circumferentially extending slot formed in an inner wall thereof;
- a radially inwardly facing fin-ring disposed in said slot and having a radially inwardly extending fin extending axially across said fin-ring, said fin having adjacent sidewalls;
- a radially inwardly extending stator blade having a base and an airfoil, said base disposed in said slot, radially inwardly of said fin-ring;
- and
- a complementary base slot disposed in said stator blade base and configured to receive said fin therein for transfer of a circumferential force, said complementary base slot having base sidewalls where said circumferential force is transferred from said base sidewalls to said adjacent sidewalls of said fin.
A turbine engine comprising:
- a multistage axial compressor having a circumferential casing;
- a circumferentially extending slot formed in an inner wall of the casing;
- a radially inwardly facing fin-ring disposed in said slot and having a plurality of radially inwardly extending fins extending axially across said fin-ring in a spaced relationship, said fins each having adjacent sidewalls;
- a stationary nozzle assembly comprising a plurality of radially inwardly extending stator blades having an airfoil and a base with a base slot disposed therein, the stator blade bases disposed in said circumferentially extending slot with said base slots receiving radially inwardly extending fins of said fin-ring for the transfer of a circumferential force, said base slots each having base sidewalls where said circumferential force is transferred from said base sidewalls to said adjacent sidewalls of said fins.
A turbine engine comprising:
- a circumferential casing having a circumferentially extending slot formed in an inner wall thereof;
- a radially inwardly facing fin-ring disposed in said slot and having a radially inwardly extending fin extending axially across said fin-ring;
- a radially inwardly extending stator blade having a base and an airfoil, said base disposed in said slot, radially inwardly of said fin-ring;
- and
- a complementary base slot disposed in said stator blade base and configured to receive said fin therein for transfer of a circumferential force, applied to said stator blade, to said fin-ring, and wherein said complementary base slot is configured to extend axially across said stator blade base between the ends thereof.
A turbine engine comprising:
- a multistage axial compressor having a circumferential casing;
- a circumferentially extending slot formed in an inner wall of the casing;
- a radially inwardly facing fin-ring disposed in said slot and having a plurality of radially inwardly extending fins extending axially across said fin-ring in a spaced relationship;
- a stationary nozzle assembly comprising a plurality of radially inwardly extending stator blades having an airfoil and a base with a base slot disposed therein, the stator blade bases disposed in said circumferentially extending slot with said base slots receiving radially inwardly extending fins of said fin-ring for the transfer of a circumferential force, applied to the stator blades, to said fin-ring, and wherein said base slots are configured to extend axially across said stator blade bases between the ends thereof.
