Abstract: An apparatus and method for minimizing and/or preventing thermal degradation of fuel in a fuel injector is disclosed. The body of the injector includes a fuel gallery with a contoured scarf formed therein. The scarf is configured to minimize and/or prevent fuel recirculation thus reducing the likelihood that fuel will dwell in an area long enough to sufficient to cause the degradation of the fuel.

Abstract: A fuel injector for a gas turbine engine is disclosed which includes an inlet fitting for receiving fuel, a nozzle for issuing fuel into the gas turbine engine, an injector body extending between the inlet fitting and the nozzle and having and interior bore extending therethrough, and an elongated fuel tube disposed within the interior bore of the injector body for delivering fuel from the inlet fitting to the nozzle. The fuel tube has an inlet end portion dynamically associated with the inlet fitting and an outlet end portion rigidly connected to the nozzle. An adapter is operatively associated with either the inlet end section of the fuel tube or a reception bore formed with the inlet fitting of the injector for accommodating a seal member in a manner that permits thermal growth of the injector body relative to the fuel tube.

Abstract: A linear semicircular trough is fabricated with intermittent vertical diaphragms placed crosswise. The diaphragms are fabricated with circular openings to permit secure placement of pipes within. The various lengths of drip pans are connected with semicircular sleeves of larger diameter bonded to the outside of the ends of the two drip pans being connected. Facility for conduction and drainage of leaked liquids is provided.
