International ClassF01D 21/00AbstractA turbofan gas turbine engine (10) comprises a fan rotor and a compressor rotor (62). The fan rotor (24) carries a plurality of circumferentially spaced radially outwardly extending fan blades (26). The compressor rotor carries a plurality of circumferentially spaced radially outwardly extending compressor blades (64). The fan rotor (24) is mounted on a fan shaft (38) and the compressor rotor (62) is mounted on a compressor shaft (68). The compressor shaft (68) is arranged around the fan shaft (38). The fan rotor (24) is rotatably mounted on a support structure (40) by a first bearing (50) and the compressor rotor (62) is rotatably mounted on the support structure (40) by a second bearing (58) spaced axially from the first bearing (50). The fan and compressor rotors (24, 62) are normally arranged coaxially with each other and with the support structure (40). The first bearing (50) is connected to the support structure (40) by a first frangible connection (54) and the second bearing (58) is connected to the support structure (40) by a second frangible connection (61).Field of SearchINCLUDING DESTRUCTIBLE, FUSIBLE, OR DEFORMABLE NON-REUSABLE PARTSHAFT BEARING COMBINED WITH OR RETAINED BY ARM OR VANE IN SURROUNDING WORKING FLUID SPACE Erodable or permanently deformable BEARING, SEAL, OR LINER BETWEEN SHAFT OR SHAFT SLEEVE AND STATIC PART HAVING FRANGIBLE OR FUSIBLE PART OR CONNECTION HAVING LUBRICATING, SEALING, PACKING OR SPECIFIC BEARING MEANS BETWEEN IMPELLER OR SHAFT AND STATIC PART With destruction sensing and preventing means Air and diverse fluid discharge from separate discharge outlets (e.g., fan jet, etc.) | |
