More Information
Summary:A gas turbine engine (20) may include a rotor overspeed protection (ROP) assembly (100). The ROP assembly (100) may include an annular blade outer air seal (BOAS) assembly (10) including a ROP segment (280). The ROP assembly (100) may include a stator vane (72) coupled with the BOAS assembly (100). The stator vane (72) may include a stator flange (78) disposed about a forward edge portion (79) of the stator vane (72). The ROP segment (280) may include a ROP flange (286) extending in an axially aft direction from a main body (282) of the ROP segment (280) toward the stator vane (72), wherein the ROP flange (286) is disposed radially inward of the stator flange (78).
