Abstract
A ring segment system (100) for a gas turbine engine (10) is disclosed. The ring segment system (100) may be formed from ring segments (50) that circumferentially surround a rotor assembly (40). The ring segments (50) may each include a carrier portion (34) that is coupled to a vane carrier (28), and a heat shielding portion (38) that is detachably coupled to the carrier portion (34). The detachable coupling may allow the heat shielding portion (38) to be uncoupled from the carrier portion (34) and removed from the gas turbine engine (10) axially. The ring segments (50) may further include cooling fluid supply channels (72) that allow cooling fluid to flow from a radially outward facing backside (42) of the ring segments (50) to a radially inward facing front side (46). Additionally, the ring segments (50) may also include ingestion prevention channels (76) that allow cooling fluid to create a barrier over the gap (80) between the ring segments (50) and the adjacent vane (18).
