摘要： An annular inlet stator vane assembly (18) positioned upstream of the bypass and core flow passages (24, 26) of a turbofan jet engine is provided with energy-absorbing bendable vanes (38) which are fixedly secured to a radially outer support shroud (42) and extend through radial slots (96,98) in an inner shroud (40). The radially inner ends of the vanes (38) are releasably secured to the inner shroud (40) by specially designed deformable retaining clips (102, 124) which are welded both to the inner ends of the vanes (38) and to the shroud (40). These features of the vane assembly (18) cooperate to limit the circumferential extent of inlet vane damage in the event of ingestion into the engine of foreign bodies such as birds, and to help to prevent damaged parts of the vane assembly from being drawn through the core passage of the engine or blocking surch core passage.
