BLADE OUTER AIR SEAL FORMED OF LAMINATE AND HAVING RADIAL SUPPORT HOOKS

A gas turbine engine (20) includes a turbine blade (102) extending radially outwardly to a radially outer tip (103) and for rotation about an axis of rotation (Z). A blade outer air seal (104, 204, 220) is positioned radially outwardly of the radially outer tip (103) of the turbine blade (102). The...

Beschreibung
Zusammenfassung:	A gas turbine engine (20) includes a turbine blade (102) extending radially outwardly to a radially outer tip (103) and for rotation about an axis of rotation (Z). A blade outer air seal (104, 204, 220) is positioned radially outwardly of the radially outer tip (103) of the turbine blade (102). The blade outer air seal (104, 204, 220) has a forward hook (118, 223) at an axially forward location and an aft hook (120, 221) at an axially aft location. An axial direction is defined by a rotational axis of the turbine blade (102). The blade outer air seal (104, 204, 220) has a central web (121) extending axially between the forward and aft hooks (118, 120, 221, 223). The forward and aft hooks (118, 120, 221, 223) extend generally radially outward from the central web (121), and have slots (146, 148, 222, 224) for being received on forward and aft support hooks (108, 110) of a blade outer air seal support (106).
