Abstract: A blade tip clearance system includes first and second control rings. The first control ring has a first coefficient of thermal expansion (CTE) and a first thermal response rate. The second control ring is located radially outward of and operatively connected to the first control ring and has a second CTE that is different from the first CTE and a second thermal response rate that is different from the first thermal response rate. Thermal expansion and contraction of the first and the second control rings controls a radial position of the blade tip clearance system relative to a rotating blade component.

Abstract: A seal assembly extends along an axis and seals an axial (and/or radial) gap between a first component and a second component. The seal assembly includes a seal carrier and a seal element. The seal element extends axially (and/or radially) between a first portion and a second portion. The first portion of the seal element is slidingly arranged within a slot in an axial end (or a radial side) of the seal carrier. The second portion of the seal element is configured to axially (and/or radially) engage the second component.

Abstract: The present disclosure relates generally to a sliding seal between two components. The sliding seal includes a seal ring including a radially extending base and an axially-extending leg disposed in a seal cavity between first and second components. A retaining ring having a first leg and a second leg defining a cavity therebetween is disposed with a portion of the base and a portion of the first component contained therein, thereby providing loading forces to help the seal ring seal against both the first and second components. One or more rope seals are carried by the seal ring in an embodiment. Other combinations of seal rings, retaining rings, and rope seals are also disclosed.

Abstract: A seal assembly for a gas turbine engine according to an example of the present disclosure includes, among other things, a seal arc segment that has a sealing portion and a first interface portion. The first interface portion defines circumferential mate faces. A support includes a mounting portion and a second interface portion. The mounting portion is configured to be fixedly attached to an engine static structure, and the second interface portion is radially inward of the first interface portion. At least one positioning member is dimensioned to abut the first and second interface portions such that the first and second interface portions are spaced apart by a predetermined distance in a radial direction.

Abstract: A core assembly for fabricating an air cooled engine component for a gas turbine engine includes an end portion for defining passages within a side of an engine component. The end portion defines a first cross-section. A middle portion is spaced apart from the end portion and defines passages through a middle part of the engine component. The middle portion defines a second cross-section. One of the first cross-section and the second cross-section includes a first height greater than a second height. An air cooled engine component for a gas turbine engine and a gas turbine engine are also disclosed.
