A core for a fan containment includes an intermediate core segment and a plenum for fluid passage defined through the intermediate core segment. The intermediate core segment has an axial inlet side, an axial outlet side opposed to the axial inlet side, a radially inner side, and a radially outer side opposed to the radially inner side. The radially outer side is configured to be operatively connected to a cylindrical outer case and the radially inner side is configured to be operatively connected to at least one arcuate panel to form a liner assembly. The plenum extends through the intermediate core segment proximate the radially outer side for fluid passage between the axial inlet side and the axial outlet side.

1. A core for a fan containment case assembly, comprising: a first core segment;a second core segment; andan intermediate core segment disposed circumferentially between the first and second core segments, wherein the core segments are configured to form at least a portion of an annular core for a fan containment case assembly, and wherein the intermediate core segment includes an axial inlet side, an axial outlet side, a radially inner side, a radially outer side, wherein the radially outer side is configured to be operatively connected to a cylindrical outer case and the radially inner side is configured to be operatively connected to at least one arcuate panel to form a liner assembly, and a plenum for fluid passage defined between the axial inlet side and the axial outlet side through the intermediate core segment proximate the radially outer side, wherein the plenum includes a fluid inlet proximate the axial inlet side and a fluid outlet opposing the fluid inlet, wherein the fluid inlet has a greater cross-sectional flow area than the fluid outlet. 2. A core as recited in claim 1, wherein the plenum extends beyond the axial outlet side of the intermediate core segment. 3. A core as recited in claim 1, wherein a portion of the plenum proximate the fluid inlet is a funnel and a portion of the plenum proximate the fluid outlet is a conduit in fluid communication with the funnel portion. 4. A core as recited in claim 3, wherein the intermediate core segment includes a plurality of ribs and the plenum includes an inner plenum wall defined between the radially outer side of the intermediate core segment and the radially inner side of the intermediate core segment, wherein the ribs extend radially from the radially inner side of the intermediate core segment to the inner plenum wall of the funnel portion of the plenum and only some of the ribs extend from the radially inner side of the intermediate core segment to the inner plenum wall of the conduit portion of the plenum. 5. A core as recited in claim 1, wherein the plenum includes an inner plenum wall defined between the radially outer side of the intermediate core segment and the radially inner side of the intermediate core segment. 6. A core as recited in claim 5, wherein intermediate core segment includes a plurality of ribs, wherein at least a portion of one of the ribs extends radially from the radially inner side of the intermediate core segment to the inner plenum wall. 7. A core as recited in claim 1, wherein the intermediate core segment includes an inner diameter segment wall on the radially inner side of the intermediate core segment and an outer diameter segment wall on the radially outer side of the intermediate core segment, wherein the outer diameter segment wall forms an outer diameter wall of the plenum, and wherein the plenum includes an inner plenum wall defined between the outer diameter wall of the plenum and the inner diameter segment wall. 8. A core as recited in claim 1, wherein the intermediate core segment and the plenum include a molded polymer selected from the group consisting of polyetherimide (PEI), polyimide, polyether ether ketone (PEEK), polycarbonate (PC), polyether ketone ketone (PEKK), polysulfone, Nylon, polyphenylsulfide, reinforced polyetherimide, reinforced polyimide, reinforced PEEK, reinforced PC, reinforced PEKK, reinforced polysulfone, reinforced Nylon, reinforced polyphenylsulfide, and combinations thereof. 9. A core as recited in claim 1, wherein the intermediate core segment and the plenum are co-molded by injection molding. 10. A core as recited in claim 1, wherein the intermediate core segment and the plenum are co-molded by compression molding. 11. A fan containment case with a drainage system, the fan containment case comprising: a cylindrical outer case with a forward end and an aft end; anda liner assembly disposed inside the cylindrical outer case, the liner assembly including a plurality of arcuate panels arranged end to end to form a cylinder and an annular core, the annular core including:a first core segment;a second core segment; andan intermediate core segment disposed circumferentially between the first and second core segments, wherein the intermediate core segment includes an axial inlet side, an axial outlet side, a radially inner side, a radially outer side, and a plenum for fluid passage defined between the axial inlet side and the axial outlet side through the intermediate core segment proximate the radially outer side, wherein the core segments are disposed radially between at least one of the arcuate panels and the cylindrical outer case, wherein the radially inner side of the intermediate core segment is engaged with at least one of the arcuate panels and the radially outer side of the intermediate core segment is engaged with the cylindrical outer case, wherein at least one of the first and second core segments is disposed radially between at least one arcuate panel and the cylindrical outer case and circumferentially between the intermediate core segment and the additional intermediate core segment. 12. The fan containment case as recited in claim 11, wherein a splice joint separates each adjacent end of the arcuate panels, wherein the intermediate core segment is operatively connected to adjacent ends of respective arcuate panels proximate the respective splice joint, and wherein at least one additional intermediate core segment is operatively connected to other adjacent ends of respective arcuate panels proximate to another respective splice joint. 13. The fan containment case as recited in claim 11, wherein the plenum extends aft of the axial outlet side of the intermediate core segment into a rear core of a rear liner, wherein the rear liner is disposed inside the cylindrical outer case aft of the liner assembly. 14. The fan containment case as recited in claim 13, wherein the rear core of the rear liner includes a groove for receiving the plenum of the intermediate core segment. 15. The fan containment case as recited in claim 11, further comprising an abradable strip liner disposed inside the cylindrical outer case forward of the liner assembly, and a rear liner disposed inside the cylindrical outer case aft of the liner assembly, wherein the plenum has a fluid inlet on the axial inlet side proximate the abradable strip liner and a fluid outlet aft of the axial outlet side within a rear core of the rear liner. 16. The fan containment case as recited in claim 11, wherein the cylindrical outer case includes a first drainage hole proximate the forward end, and a second drainage hole proximate the aft end, wherein the plenum provides a fluid passage between the forward end and the aft end for fluid drainage out of at least one of the first drainage hole and the second drainage hole. 17.
