A sealing system for a fuel injector is provided. The fuel injector includes a body defining a plurality of fuel passages. Each of the plurality of fuel passages is defined by a first portion of the body and a second portion of the body. The sealing system includes a sealing structure adapted to be disposed between the first portion and the second portion. The sealing structure extends circumferentially around a central axis of the fuel injector. The sealing structure includes a ring and a plurality of lobes. Each lobe from the plurality of lobes is adapted to accommodate and seal a corresponding fuel passage from the plurality of fuel passages. The sealing system also includes a plurality of mechanical fasteners adapted to couple the first portion with the second portion, and to apply a pressure on the sealing structure to seal the plurality of fuel passages.

Fueling passage array sealing system and method of use

Exhaust outlets (e.g., in a gas turbine engine) are generally made from sections of thin-walled materials (e.g., sheet metal) that are joined by flanges. Due to the length of the exhaust outlet and differing thermal expansion coefficients exhibited by the flanges and the thin-walled materials, these joints are subjected to high mechanical, as well as thermal, stresses. A long-arm flange is disclosed that decouples the mechanical stress from the thermal stress in the flange and distributes the stress, to thereby reduce the stress at the flange interface. Additionally, the long-arm flange can be easily adapted to the specific geometry of any exhaust outlet.

A thermal bridge forms a connection between a cold side and a hot side that is capable of withstanding a large temperature differential while high-pressure gas (e.g., air) flows between the two sides within an internal passageway. A cold-side region and hot-side region of the thermal bridge may each have a flange with a plurality of holes. The cold-side region may also include a conical fillet with counterbore recesses to provide access to each of the plurality of holes from a low radial position.
