摘要： A blade outer air seal assembly (105) contains a support structure (112). A blade outer air seal (106) extends circumferentially about an axis (A) and is mounted in the support structure (112). The support structure (112) has a first support member (118) that engages a first axial side (A1) of the blade outer air seal (106). A second support member (120) engages a second axial side (A2) of the blade outer air seal (106). A retaining clip (152, 252) secures the blade outer air seal (106) to the support structure (112). The retaining clip (152, 252) has a first leg (160, 260) and a second leg (158, 258) that extends in a generally radial direction. The first leg (160, 260) abuts the first axial side (A1) and the second leg (158, 258) abuts the first support member (118).

摘要： A gas turbine engine (20) includes a compressor section (24) and a turbine section (28). The turbine section (28) includes at least one turbine rotor having a radially extending turbine blade (102). The turbine section (28) is rotatable about an axis of rotation (A). A blade outer air seal (104) is positioned radially outwardly of a radially outer tip of the at least one turbine blade (102). The blade outer air seal (104) has axially spaced forward and aft portions (106, 108) and a central web (99) between the axially spaced portions (106, 108). An attachment block (110, 136) is supported on structure within the engine (20). The attachment block (110, 136) mounts the blade outer air seal (104). A passage (118) extends into a central chamber (131) within the attachment block (110, 136), and communicates with cooling holes (120) through a radially inner face of the attachment block (110, 136) to direct cooling air at the central web (99) of the blade outer air seal (104).
