    Abstract: PROBLEM TO BE SOLVED: To provide a damping configuration for stator vanes (29) in a stator assembly for a gas turbine engine.SOLUTION: The stator subassembly includes an array of circumferentially arranged stator vanes (29). Attachment liners (100, 102) secure the stator vanes (29) to one another to provide the subassembly. Damping springs (104, 106) are integral with the attachment liners (100, 102) and are provided between the array of the stator vanes (29) and an outer case (90) which supports the array. The damping springs (104, 106) are provided to bias the array of the stator vanes (29) radially inwardly from the outer case (90).

    Abstract: PROBLEM TO BE SOLVED: To provide a damper spring which stabilizes a stator assembly and minimizes vibration.SOLUTION: The stator assembly 26 includes: an outer case 28; a stator subassembly having columns including stator vanes which are circumferentially arranged; and a damper spring 44 which is provided between the columns and the outer case 28, and is configured to bias the columns from an outer case to a radial inner circumferential side. Moreover, the assembly 26 includes a first attachment liner 40 and a second attachment liner 42 to which a first hook 34 and a second hook 36 of a stator vane are secured, respectively. The stator vane includes a recess 46 having lateral walls 48 and an adjoining bottom wall 50. The damper spring 44 engages with the outer case 28, the lateral walls 48 and the bottom wall 50.

    Abstract: A stator subassembly includes an array of circumferentially arranged stator vanes. A damper spring is provided between the array and an outer case, which supports the array. The damper spring is configured to bias the array radially inwardly from the outer case. The damper spring stabilize the stator and damp vibrations. The damper spring may be configured to offer multiple contact points to provide stator stability.

    Abstract: A stator assembly for a turbofan gas turbine engine is disclosed. The stator assembly is coupled to a shroud of the engine. The stator assembly includes an endless case fixedly coupled to the engine shroud. The case includes a forward portion, an aft portion and a central portion disposed therebetween. The case extends about an axis of the engine. The forward and aft portions of the case include rails that extend towards each other and form forward and aft pockets with the central portion respectfully. The stator assembly also includes a locking stator segment. The locking stator segment includes a shroud that includes a forward hook and a pair of aft hooks with a platform disposed therebetween. The forward and aft hooks are retained in the forward and aft pockets of the case respectfully.
