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.

1. A liner system comprising: a fan track liner panel positionable axially within a casing arranged around a rotatable fan and forming a blade containment zone, the fan track liner panel positionable radially outward of the rotatable fan;the fan track liner panel comprising:a body extending 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 fore portion divided from the aft portion by a seam in the body, the seam configured to act as a mechanical fuse; andwherein the fan track liner panel is configured to be directly secured to the casing by a fastener extending through only part of the body and at least partially 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, and the fore portion of the fan track liner panel extends away from the casing to define a cavity between the interior surface of the casing and a surface of the fore portion of the fan track liner panel. 2. The liner system of claim 1, wherein the fastener is a plurality of fasteners spaced apart along a length of only the aft portion of the fan track liner panel. 3. The liner system of claim 1, wherein the fastener is a bolt used in conjunction with a nut. 4. The liner system of claim 3, wherein the nut is embedded in the body of the fan track liner panel as a potted insert. 5. The liner system of claim 3, wherein the body defines a body cavity configured to receive the bolt. 6. The liner system of claim 1, further comprising an abradable layer layered along a surface of the body extending the length of the fan track liner panel from the fore portion to the aft portion of the fan track liner panel. 7. The liner system of claim 1, further comprising an abradable layer layered along a surface of the body extending along the length of the fan track liner panel, the abradable layer defining a notch, wherein the notch aligns with a second end of the seam, and wherein the notch is configured to act as a separation point. 8. The liner system of claim 1, wherein the seam is configured to be positioned directly upstream of the fastener. 9. The liner system of claim 1, wherein the cavity is configured to receive a detached fan blade fragment. 10. The liner system of claim 1, wherein the seam is configured to enable the fore portion to move independent of the aft portion during a blade off event. 11. The liner system of claim 10, wherein a first end of the seam is configured to abut the interior surface of the casing, and wherein the first end of the seam is configured to act as a first pivot point during the blade off event. 12. The liner system of claim 10, wherein the seam is configured to extend substantially perpendicularly from the interior surface of the casing to a second end of the seam, the second end configured to separate during the blade off event. 13. A liner system comprising: a fan track liner panel positionable axially within a casing arranged around a rotatable fan and forming a blade containment zone, the fan track liner panel positionable radially outward of the rotatable fan;the fan track liner panel comprising:a first body and a second body separated by a seam, the first body and the second body layered between a first surface and a second surface, the first surface configured to face away from the casing and the second surface configured to face toward the casing, the second surface including a first portion along the first body and a second portion along the second body;wherein the first body is configured to be secured to the casing by a fastener extending through the casing in the blade containment zone such that the first portion of the second surface is contiguously aligned with the casing in parallel with a surface of the casing; andwherein the second body is configured to project away from the casing toward the rotatable fan to form a cavity between the second portion of the second surface and the surface of the casing. 14. The liner system of claim 13, wherein the first surface is an abradable material. 15. The liner system of claim 13, wherein the first surface includes a first portion along the first body and a second portion along the second body, and wherein the first and second portions of the first surface are separated by a notch on the first surface. 16. The liner system of claim 15, wherein the notch is aligned with the seam. 17. The liner system of claim 15, wherein the seam is configured to act as a mechanical fuse and the notch is configured to act as a separation point when the second portion of the first surface is struck by a detached fan blade fragment, such that the second body moves toward the casing to accept the detached fan blade fragment. 18. The liner system of claim 13, wherein the seam is configured to be positioned substantially perpendicularly to the surface of the casing. 19. The liner system of claim 13, wherein the seam is configured to be immediately adjacent to the fastener. 20. A liner system comprising: a fan track liner panel positionable axially within a casing arranged around a rotatable fan and forming a blade containment zone, the fan track liner panel positionable radially outward of the rotatable fan;the fan track liner panel comprising:a body layered between a first surface and a second surface, the first surface configured to face away from the casing and the second surface configured to face toward the casing; anda seam positioned between a first end of the fan track liner panel and a second end of the fan track liner panel, the seam extending through the body from the first surface to the second surface;wherein the fan track liner panel is configured to be secured to the casing by a fastener extending through the casing in the blade containment zone, such that a portion of the second surface between the seam and the second end of the fan track liner panel is in continuous contact with a surface of the casing. 21. A liner system comprising: a fan track liner panel positionable axially within a casing arranged around a rotatable fan and forming a blade containment zone, the fan track liner panel positionable radially outward of the rotatable fan;the fan track liner panel comprising:a body extending 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 fore portion divided from the aft portion by a seam in the body, the seam configured as a mechanical fuse to enable the fore portion to move independent of the aft portion during a blade off event; andwherein the fan track liner panel is configured to be secured to 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, and the fore portion of the fan track liner panel extends away from the casing to define a cavity between the interior surface of the casing and a surface of the fore portion of the fan track liner panel, the fore portion pivotably movable independent of the aft portion, into the cavity, during the blade off event.
