  • Publication number: 20240133298
    Abstract: A turbine blade includes an airfoil section, wherein at least one cooling hole is formed a tip floor of the airfoil section, which is fluidically connected to an internal coolant cavity of the airfoil section. The turbine blade further includes an additively manufactured tip cap formed via layer-by-layer deposition of material directly over the tip floor of the airfoil section. The tip cap includes at least one squealer tip rail extending outward from the tip floor. The at least one squealer tip rail comprises an embedded cooling channel formed therein. The embedded cooling channel is aligned with and fluidically connected to the at least one cooling hole formed through the tip floor of the airfoil section. The embedded cooling channel comprises one or more outlets located on at least one of a side face and a top face of the at least one squealer tip rail.

  • Publication number: 20240068368
    Abstract: A turbine blade includes a platform, a blade airfoil attached to one side of the platform, a blade root attached to the other side of the platform, a manifold attached to the blade root. The blade root defines a first cooling passage and a second cooling passage. The manifold includes an outer wall, a first compartment having a first flow area defined by a first aperture formed at the outer wall, and a second compartment having a second flow area defined by a second aperture formed at the outer wall. The first compartment meters a non-zero first flow of cooling air to the first cooling passage through the first flow area. The second compartment meters a non-zero second flow of cooling air to the second cooling passage through the second flow area that is different than the first flow area.

  • Patent number: 11365638
    Abstract: A turbine blade tip includes a squealer tip wall having a forward surface that is continuous with an outer surface of an airfoil pressure sidewall. A plurality of cooling channels are provided spaced apart along a contour of the squealer tip wall. Each cooling channel includes: an inlet configured for receiving a coolant from airfoil internal cavity; an upstream section including a closed channel extending from the inlet to the forward surface of the squealer tip wall; and a downstream section including an open channel formed by a slot on the forward surface of the squealer tip wall. The slot extends radially outward in a downstream direction so as to guide the coolant along the forward surface toward a radially outermost tip of the squealer tip wall.
