A gas turbine engine component may include an airfoil extending radially from a base to a blade tip, the airfoil including a pressure sidewall and a suction sidewall each extending between a leading edge and a trailing edge opposite the leading edge, an internal cooling circuit extending from the base to the blade tip; and a squealer tip. The squealer tip may include a first and a second squealer tip rail adjacent to the first squealer tip rail, and a squealer tip cap extending between the first and second squealer tip rails. The blade tip, the first and second squealer tip rails, and the squealer tip cap may define an internal squealer tip cooling channel. The blade tip may define a supply aperture that fluidly connect the internal cooling circuit and the internal squealer tip cooling channel.

Turbine blade squealer tip including internal squealer tip cooling channel

A blade track system includes a blade track configured to be positioned around a plurality of blades of a gas turbine engine. The blade track includes: a full-hoop body, an inlet port, and an exit port. The full-hoop body includes an outer surface and an inner surface. The inner surface defines an internal cooling channel extending within the full-hoop body. The inlet port and the exit port are each integrated with the full-hoop body and in fluid communication with the internal cooling channel.

Full hoop blade track with internal cooling channel

A blade track assembly for a gas turbine engine includes a plurality of blade track segments. The blade track segments are arranged circumferentially around a central axis to form a blade track. Each of the plurality of blade track segments includes a first circumferential end face, a second circumferential end face opposite the first circumferential end face, a radially-outer surface, and a radially inner surface opposite the radially-outer surface.

Apparatus and systems for a cooled gas turbine engine flowpath component are disclosed. In some embodiments, the flowpath component includes a spar and a coversheet. The spar may include a suction-side wall extending from a leading edge to a trailing edge and a pressure-side wall extending from the leading edge to the trailing edge, each wall having an outer surface. The coversheet may be positioned on the spar to at least partially enclose the spar, the coversheet having an engagement surface positioned to face the outer surface of the suction-side wall and the outer surface of the pressure-side wall. The spar and the coversheet cooperate to form a number of passageways configured to cool the flowpath component.
