A blade retainer clip for retaining a foot of a turbine blade in a shoe of a turbine disc of a turbine wheel includes: a clip shank that fits into a mating slot in the blade foot; a protuberance along a central portion of the clip shank that fits into a mating recess along the mating slot in the blade foot; a clip heel on one end of the clip shank that engages a heel of the blade foot and a heel of the disc shoe that expands radially from at least opposite sides of the clip shank; and a clip toe that extends beyond a toe of the disc shoe that is deformable to contact at least the toe of the disc shoe.

Blade retainer clip

A blade retention system for retaining a foot of a turbine blade in a shoe of a turbine disc of a turbine wheel includes: a hook on a heel end of the blade foot that protrudes from a bottom of the blade foot to engage a heel end of the turbine disc shoe; and a compound fillet that engages the hook with the bottom of the blade foot.

Blade retainment system

A gas turbine engine includes a radial compressor having first and second blades. The first blade has a tuned leading edge that prevents either blade from exciting at a natural frequency at speeds within an expected operating speed range.

Radial compressor of asymmetric cyclic sector with coupled blades tuned at anti-nodes

A gas turbine engine includes a radial compressor with first and second blades. The first and second blades have tuned leading edges that prevent natural frequencies from exciting at speeds within an expected operating speed range.

Radial compressor with blades decoupled and tuned at anti-nodes

A rotor blade suitable for use in a gas turbine engine includes an attachment section which defines at least one internal cooling passage along a passage axis through the attachment section.

Coolable airfoil attachment section

A method and system for determining the reliability of a rotating component compares a normalized stress curve with a normalized strength curve. The resulting overlap corresponds with the reliability of the rotating component.
