Abstract
An aircraft engine anti-icing barrier assembly having a slip joint subassembly, a barrier subassembly, and a vapor barrier subassembly. The slip joint subassembly has a forward end for fixed attachment at a forward bulkhead of an aircraft engine, and has an aft end having a sliding joint. The barrier subassembly is attached to an aft side of an aft bulkhead and inserted through the aft bulkhead. The barrier subassembly has two mount pads with an upper mount pad and a lower mount pad configured for joined sealed attachment around the slip joint subassembly to form a barrier between an engine fan case compartment and an aft compartment in an engine inlet. The vapor barrier subassembly is attached to the aft side of the aft bulkhead and adjacent the barrier subassembly, has a boot element and a boot element retainer, and forms a vapor barrier to the slip joint subassembly.
