摘要： A method and system is described herein for using a polyimide adhesive to bond a first metal layer to a second metal layer used in a gas turbine engine. The polyimide adhesive may be a film or a paste and is able to withstand operating temperatures in excess of 600 degrees Fahrenheit (315 degrees Celsius). In an exemplary embodiment, the second metal layer is an outer face skin of an exhaust nozzle and the first metal layer is a metal doubler configured to cover a damaged portion of the outer face skin. In some embodiments, the first and second metal layers may be formed of titanium.

摘要： A laminate air seal for a gas turbine engine includes at least one fabric layer made of fiberglass, ceramic fiber, basalt and/or carbon, and a polymeric resin that is stable at an operating temperature of the gas turbine engine. The resin may be preimpregnated into the fabric layers, or introduced into the fabric during assembly and formation of the laminate. The resin may be polyimide, bismaelimide (BMI) or cyanate ester. A particular resin selected may depend, in part, on the operating temperatures in that region of the gas turbine engine. In some embodiments, the laminate seal may include a coating to increase lubricity of the seal. In one embodiment, the laminate air seal is used to seal a gap between a pylon fairing and an exhaust nozzle of the turbine engine.

摘要： A method and system of repairing an engine part having a cracked metal skin bonded to a honeycomb core includes removing a portion of the honeycomb that corresponds to a cracked portion of the metal skin. A crack in the metal skin originates from an edge of the engine part. A portion of the honeycomb is removed to form a slot in the honeycomb beginning at the edge of the part. A doubler is inserted into the slot in the honeycomb and is attached to an underside of the metal skin to form a lap joint between the doubler and the metal skin. In one embodiment, the portion of the metal skin that includes the crack remains. In an alternative embodiment, the cracked portion of the metal skin is removed and a metal patch is attached to the doubler such that the patch replaces the removed metal skin.
