Abstract

An example blade outer air seal support assembly (50) includes a main support member (54) configured to support a blade outer air seal (60). The main support member (54) extends generally axially between a leading edge portion (56) and a trailing edge portion (58). The leading edge portion (56) is configured to be slidably received within a groove (62) established by the blade outer air seal (60). A support tab (68) extends radially from the support member (54) toward the blade outer air seal (60). The support tab (68) is configured to contact an extension of the blade outer air seal (60) to limit relative axial movement of the blade outer air seal (60). A gusset (72) spans between the support tab (68) and the support member (54). The blade outer air seal (60) has an inwardly facing surface (80). A blade path portion (102) of the inwardly facing surface is axially aligned with a tip (78) of a rotating blade (76). A peripheral portion (104) of the inwardly facing surface (80) is located axially in front of the blade path portion (102), axially behind the blade path portion, or both. The blade outer air seal establishes cooling paths that terminate at a plurality of apertures (110) established within the inwardly facing surface (80) and located exclusively within the blade path portion (102).
