摘要： The present disclosure provides a liner system for a turbine engine (10). The liner system includes a fan track liner panel (32) that is positionable axially within a casing (20) that is arranged around a rotatable fan (14) and that forms a blade containment zone. The fan track liner panel (32) is further positionable radially outward of the rotatable fan (14). The fan track liner panel (32) includes a body (34) that extends a length of the fan track liner panel (32) from a fore portion (36) of the fan track liner panel (32) to an aft portion (38) of the fan track liner panel (32). The fan track liner panel (32) is configured to be directly secured to the casing (20) by a fastener (40) that extends through only part of the body (34) and entirely through the casing (20) within the blade containment zone such that the aft portion (38) of the fan track liner panel (32) abuts an interior surface (21) of the casing (20).

摘要： Methods and systems to electrically assist an internal combustion engine of an aircraft may be provided. A first bladed rotor may be rotated by a first internal combustion engine. Electricity may be generated from a first motor generator by rotating a first shaft of the first motor generator with the first internal combustion engine. In response to a predetermined event, such as an engine failure, mechanical power may be generated from the first motor generator instead of electricity. The mechanical power may be transferred to the first bladed rotor. The mechanical power may be generated by applying electricity to the first motor generator. The electricity applied is received from a second motor generator, where the electricity received from the second motor generator is generated by rotating a second shaft of the second motor generator with a second internal combustion engine that powers a second bladed rotor.
