    摘要: A platform spacer is joinable to a rotor disk between adjacent rotor blades having dovetails retained in a circumferential dovetail groove therein. The spacer includes a platform having a flat upper surface sized for abutting adjacent blade platforms to form an inner flowpath, and first and second hooks extending downwardly from the platform lower surface. The first and second hooks are configured for insertion radially inwardly through first and second loading recesses in the rotor disk for retention thereto.

    摘要: A gas turbine engine rotor blade includes an airfoil joined to a dovetail. The dovetail includes a shank from which extends two pairs of dovetail tangs being defined by a bifurcating slot disposed therebetween. The dovetail is configured for retention in a complementary dovetail groove in a rotor disk with the bifurcating slot remaining empty for reducing weight of the blade while transferring centrifugal loads from the blade to the rotor disk.

    摘要: A rotor blade for a gas turbine engine includes an airfoil, platform and dovetail. The platform has top and bottom surfaces, with a plurality of pockets disposed in the bottom surface for reducing weight of the platform, with the pockets defining a plurality of continuous beams extending along the platform which provide structural stiffness to the platform to avoid resonance vibration thereof during operation.

    摘要: A spacer band for maintaining uniform spacing between adjacent compressor liner segments comprising two segments having a plurality of locking fingers extending from the band for engaging the casing at both ends of the liner segments and in the middle of the segments. The spacer band is located in a vertical channel located along an edge of each liner segment. The vertical channel is defined by a plurality of vertical flanges and a horizontal flange located on the edge of each liner segment. The horizontal flange has notches for receiving said locking fingers.
