An air seal is provided which extends axially between a first side and a second side. The air seal includes an axial flange, a radial flange, a seal element, a retainer neck and a retainer head. The axial flange extends axially to the second side. The radial flange is connected to the axial flange at the second side. The radial flange projects radially outward from the axial flange to a distal end. The seal element projects radially outward from the distal end of the radial flange. The retainer neck is connected to the radial flange at the distal end of the radial flange. The retainer neck projects axially out from the radial flange towards the first side and then projects radially outward to the retainer head. The retainer head projects axially towards the first side and away from the retainer neck to an axial end of the retainer head.

A balance ring for a gas turbine engine has a ring shaped body with a first radial thickness, an anti-rotation tab extending outward from the body and at least one millable balancing feature connected to the body.

An assembly according to an exemplary aspect of the present disclosure includes, among other things, a disk, a cover plate providing a cavity at a first axial side of the disk, a passageway including an inlet provided by a notch in at least one of the disk and the cover plate in fluid communication with the cavity, and the passageway extending from the inlet to an exit provided at a second axial side of the disk opposite the first axial side, the exit in fluid communication with the inlet, and the passageway configured to provide fluid flow from the cavity to the exit.

Feature to provide cooling flow to disk

A seal assembly for a gas turbine engine includes a primary seal that includes an inner face that has a protrusion configured to seal relative to a seal land. The protrusion provided on segmented shoes is circumferentially spaced from one another by gaps. The shoes are positioned in a relaxed state. A removable material encases the protrusion with the shoes in the relaxed state.

A rotating component for a turbine engine includes a rotor portion protruding radially outward, at least one overweight region is located in the rotor portion, and at least one additively manufactured counterweight region is positioned relative to the at least one overweight region such that the rotating component is circumferentially balanced.

A cover plate assembly according to an exemplary aspect of the present disclosure includes, among other things, a first cover plate and a second cover plate in contact with a portion of the first cover plate to at least axially retain the first cover plate.

A rotor disk is provided. The rotor disk may comprise a disk lug and a trench. The disk lug may be fixed to a distal surface of the rotor disk. The trench may be disposed on a surface of the disk lug. The trench may extend radially inwards from a distal surface of the disk lug. The trench may be configured to at least partially define a flow path by which cooling air may reach a distal surface of the disk lug in order to provide disk lug cooling.

Disk lug cooling flow trenches

A gas turbine engine section comprises a rotatable shaft, first and second axially adjacent components, a nut, and a multifunction positioning lock washer. The first and second axially adjacent components are located on the rotatable shaft and are separated by an axial separation distance. The nut is configured to thread onto the rotatable shaft to hold one of the first and second axially adjacent components in compression. The multifunction positioning lock washer has antirotation geometry configured to prevent the nut from tightening or loosening. The axial length of the multifunction positioning lock washer is adjusted by removing material based on measurement of the axial separation distance to take in tolerances and reduce the axial separation distance.
