  • Liner system
    Patent number: 10260522
    Abstract: The present disclosure provides a liner system for a turbine engine. The liner system includes a fan track liner panel that is positionable axially within a casing that is arranged around a rotatable fan and that forms a blade containment zone. The fan track liner panel is further positionable radially outward of the rotatable fan. The fan track liner panel includes a body that extends a length of the fan track liner panel from a fore portion of the fan track liner panel to an aft portion of the fan track liner panel. The fan track liner panel is configured to be directly secured to the casing by a fastener that extends through only part of the body and entirely through the casing within the blade containment zone such that the aft portion of the fan track liner panel abuts an interior surface of the casing.
