A method of installing a seal in a bore of a component includes, among other things, slidably orienting the component in a support fixture. The method includes securing a base plate to the component. The method includes arranging the seal onto a pusher. The method also includes inserting the pusher into a hole in the base plate. The method further includes installing a hub onto the base plate and over the pusher. The method further includes rotating a rod relative to the hub to advance the pusher and seat the seal in the bore.

Seal installation tool

A hybrid grommet assembly for a vane comprising a body portion comprising a first lip opposite a second lip forming a slot receiver, said slot receiver configured to receive a shroud slot of a shroud; said body portion comprising a vane receiver extending from said body portion and configured to receive a vane; a fiber integral within said body portion; and a potting coupled to said grommet proximate said vane receiver, wherein said potting fills a gap between the grommet and the vane.

The boss extending from a proximal end located at the first end surface to a distal end located opposite the proximal end. The boss includes: a passageway extending from the distal end to the second end surface through the boss; an external surface extending from the proximal end to the distal end; and a seal groove in the external surface located at the proximal end of the boss.

Circular seal outer diameter seal effectiveness testing tool

A tool for seating a wear liner into a first groove of a fan case of a gas turbine engine includes a body, a handle, and a first guide foot. The body includes a first end and a second end. The handle is connected to and extends from the body. The first guide foot is connected to and extends from the first end of the body. The first guide foot includes a first end connected to the body and a second end opposite from the first end of the first guide foot. The second end of the first guide foot is rounded and includes a chamfered portion.

Wear liner installation tool

The present disclosure provides a wear liner for a stator vane that has a first hook and a second hook that are connected by a base, providing in a generally S-shaped channel. The wear liner includes an outer surface that is adapted to lie against a first component and an inner surface that is adapted to lie against a second component. The first hook of the wear liner includes a first engaging end that is adapted to engage a first component, while the second hook is adapted to engage the second component. The first component may comprise a vane foot and the second component may comprise a slot for receiving and securing the vane foot.

Wear liner for fixed stator vanes

A method of installing a seal in a bore of a component includes securing a base plate to a component. The method includes arranging the seal onto a pusher. The method also includes inserting the pusher into a hole in the base plate. The method further includes installing a hub onto the base plate and over the pusher. The method further includes rotating a rod relative to the hub to advance the pusher and seat the seal in the bore.

A vane for use with a stator assembly is disclosed herein. The vane having: an upper mounting portion; a lower mounting portion; an airfoil body extending between the upper mounting portion and the lower mounting portion; a first integrally formed metal fillet located between the upper mounting portion and the airfoil body, the first integrally formed metal fillet defining a first mounting surface located between the upper mounting portion and first integrally formed metal fillet; and a second integrally formed metal fillet located between the lower mounting portion and the airfoil body, the second integrally formed metal fillet defining a second mounting surface located between the lower mounting portion and second integrally formed metal fillet.

A gas turbine engine includes an annular structure disposed around an engine central longitudinal axis of the gas turbine engine. The annular structure defines an annular channel and comprises a first density, according to various embodiments. The gas turbine engine may further include a weight-saving filler disposed within the annular channel. The weight-saving filler may have a second density that is less than the first density. The gas turbine engine may further include an annular retention strap disposed around the engine central longitudinal axis of the gas turbine engine. The annular retention strap is at least partially embedded in the weight-saving filler, according to various embodiments.

Annular retention strap

An inner shroud segment may include an inner housing and an outer housing. The inner housing may have a radial curve centered relative to an axis with a radial wall and a bottom wall that define a first channel. The outer housing may have a first axial wall, a first circumferential wall, and a second axial wall that define a second channel. The outer housing may also be disposed within the first channel with the radial wall of the inner housing contacting the first axial wall, the first circumferential wall, and/or the second axial wall. A compliant material may be disposed within the second channel and coupled to the radial wall and the first axial wall, the first circumferential wall, and/or the second axial wall.

Two pieces stator inner shroud

A stator assembly having: an inner air seal carrier having a mounting body; a plurality of guide vanes secured to the mounting body via a plurality of fasteners; and a fastener retention mechanism secured to the mounting body via the plurality of fasteners. The fastener retention mechanism having: a housing defining an inner chamber; and a filler located within the inner chamber. The portions of the plurality of fasteners are encapsulated within the filler.

Fastener retention mechanism

A vane assembly may comprise an engine case and an anti-rotation lug coupled to the engine case. The anti-rotation lug may have a forward end and an aft end. A vane cluster may be supported within the engine case. The vane cluster may include an outer shroud with a first slot defined by a forward flange of the outer shroud and with a second slot defined by an aft flange of the outer shroud. The second slot may be configured to receive the aft end of the anti-rotation lug from first direction and wherein the aft flange may be configured to block receipt of the anti-rotation lug from a second direction, which is opposite the first direction.

Anti-rotation stator vane assembly
