    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 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 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.
