    摘要： A material having a plurality of impurity collection spaces has an outer face facing into a cooling air flow stream for a gas turbine engine component. Impurities such as sand or dirt will collect in the plurality of spaces. In a disclosed embodiment, a honeycombed material is utilized. The material may have a surface that will sit with at least a component parallel to an axial centerline of a gas turbine engine that is to receive the collection material. The material surface may also have a component which is generally perpendicular to the axial centerline. The material may be placed in a gas turbine engine upstream of the turbine section, and downstream of the combustion section. Moreover, the collection material may be placed such that there is cleaner air flow radially inwardly of the collection material, and heavier dirt-laden air passing along the collection material such that impurities can be collected.

    摘要： A turbine blade outer air seal segment assembly has a first turbine blade outer air seal segment with a first end portion, a middle portion and a second end portion. The first turbine blade outer air seal segment is for connection with a second turbine blade outer air seal segment to form at least a part of a shroud of a turbine rotor. A first cooling passage is disposed within the first turbine blade outer air seal segment. The cooling passage extends from the first end portion to the second end portion and a land is disposed in at least one of the first or second end portions. The land represents a portion for receiving a mold ejection pin for a core forming the cooling passage.

    摘要： An article of manufacture has a body formed in part of a first metal alloy and in part of a second metal alloy, the second metal alloy having a thermal coefficient of expansion that is less than the thermal coefficient of expansion of the first metal alloy. A BOAS segment for a gas turbine engine is disclosed wherein the formation of cracks due to thermal mechanical fatigue in the body of the disclosed BOAS segment is minimized, if not eliminated, through a unique construction of the disclosed BOAS segment, whether original equipment manufacture or a repaired blade outer air seal. A method for manufacture of a BOAS segment and a method for modifying a BOAS segment are disclosed.
