Title:
LOW STRESS CIRCUMFERENTIAL DOVETAIL ATTACHING DEVICE FOR ROTOR BLADE
Document Type and Number:
Japanese Patent JP2010270754
Kind Code:
A
Abstract:
To provide a retaining system for a circumferential entry type rotor dovetail, inserted into a dovetail slot in a rotor.
A plurality of rotor blade dovetails 118 are circumferentially slidable into and along the dovetail slot 110, with each rotor blade dovetail having a neck 120 and a pair of oppositely oriented lobes 122. A plurality of rail segments 126 are circumferentially slid into channels in the dovetail slot between the dovetail lobes and the respective disk hoops 106, 108. The rail segments define a first pressure face 138 that engages with an outward pressure face of the dovetail lobes, and a second pressure face 140 that engages with an inward pressure face of the respective disk hoop component.
