US Classification:

416193A, 416219 R, 416245 R, 416248

Abstract:

A gas turbine engine rotor disk has a number of annular hubs circumscribed about a centerline and each of the hubs is connected to a disk rim by a web. A plurality of circumferentially spaced apart circular arc dovetail slots are disposed through the rim. Circumferentially extending annular burst slots extend radially through the rim into the dovetail slots between each adjacent pair of the webs. The fan blades have circular arc dovetail roots disposed within the circumferentially spaced apart circular arc dovetail slots. A one piece spinner attached to a forward extension of the disk at a location between a tip and an axially aft spinner end of the spinner. Non-integral platforms circumferentially disposed between the fan blades. A booster spool is connected to the rotor disk by a mounting plate therebetween and the platforms are radially retained to the disk and mounting plates by pins through holes in mounting lugs depending radially inwardly from the platforms. Pairs of circumferentially oppositely facing retaining slots have retainers disposed therein which extend across the dovetail slots to axially retain the dovetail roots in the dovetail slots.

Wayne Ray Bowen - West Chester OH

Assignee:

General Electric Company - Schenectady NY

International Classification:

F01D 1716

US Classification:

415160, 415229, 384273

Abstract:

A trunnion support for a variable-position stator vane in a turbomachine. The stator vane includes an upper trunnion and a lower trunnion to allow the stator vane to be pivoted about a longitudinal axis. The lower trunnion is supported in a bushing that is carried in an opening provided in an annular stator vane carrier ring. The bushing is longitudinally split and is installed in the carrier ring while in a laterally compressed condition so that when installed in the carrier ring the bushing bears against the carrier ring opening in which it is positioned. When the carrier ring material expands with rising temperature, the pre-stress in the bushing will cause it to expand to maintain tight frictional engagement between the bushing and the opening and thereby prevent relative rotation between the bushing and the carrier ring to minimize wear of the carrier ring material.
