摘要： An example blade outer air seal support assembly includes a main support member configured to support a blade outer air seal. The main support member extends generally axially between a leading edge portion and a trailing edge portion. The leading edge portion is configured to be slidably received within a groove established by the blade outer air seal. A support tab extends radially from the support member toward the blade outer air seal. The support tab is configured to contact an extension of the blade outer air seal to limit relative axial movement of the blade outer air seal. A gusset spans between the support tab and the support member.

摘要： An example blade outer air seal support assembly includes a main support member configured to support a blade outer air seal. The main support member extends generally axially between a leading edge portion and a trailing edge portion. The leading edge portion is configured to be slidably received within a groove established by the blade outer air seal. A support tab extends radially from the support member toward the blade outer air seal. The support tab is configured to contact an extension of the blade outer air seal to limit relative axial movement of the blade outer air seal. A gusset spans between the support tab and the support member. An example blade outer air seal assembly includes a blade outer air seal assembly having an inwardly facing surface. A blade path portion of the inwardly facing surface is axially aligned with a tip of a rotating blade. A peripheral portion of the inwardly facing surface is located axially in front of the blade path portion, axially behind the blade path portion, or both. The blade outer air seal assembly establishes cooling paths that terminate at a plurality of apertures established within the inwardly facing surface. The plurality of apertures are locate exclusively within the blade path portion.

摘要： An example blade outer air seal assembly for a gas turbine engine includes a main body portion extending along an axis. The main body portion has a radially inward facing surface and at least one radially outward facing surface. A passage is provided in the main body portion between the at least one radially inward facing surface and the at least one radially outward facing surface. The passage has a first portion and a second portion transverse to the first portion, and at least one rib disposed along the axis radially outward of the second portion.

摘要： A multi impingement plate assembly for a Blade Outer Air Seal (BOAS) includes a first impingement plate which defines a multiple of first impingement plate holes and a second impingement plate attached to the first impingement plate. The second impingement plate includes a platform section spaced away from the multiple of first impingement plate holes to define a plate cavity.
