Abstract: A fuel nozzle for use in a gas turbine engine is provided. The fuel nozzle has a fuel nozzle tip with an outer tip housing. The tip housing has a recess formed at an inner surface of the tip housing. A shim is disposed within the recess and a surface of the shim contacts a diaphragm of the fuel nozzle tip. A thermal adjustment member is disposed within the recess against the shim. The tip housing, diaphragm and shim are formed of a base material having a coefficient of thermal expansion (?1) and the thermal adjustment member is formed of a different material having a coefficient of thermal expansion (?2) higher than the coefficient of thermal expansion (?1) of the base material.

Abstract: A gas turbine engine includes a turbine having a plurality of vanes, a plurality of blades, a turbine shroud arranged around the vanes and blades, and a turbine case arranged around the turbine shroud. The turbine shroud is sized to block combustion products from passing over the blades without pushing the blades to rotate. The turbine shroud includes a runner arranged around the blades and a carrier arranged around the runner.

Abstract: A gas turbine engine airflow member is disclosed having spherical interface shapes at a tip end and a hub end. In one embodiment, the airflow member is a fan blade. The spherical interface shapes can be convex or concave. In one form, the tip end spherical shape is axially shifted aft relative to a hub end. The tip end can include relatively little forward portion in an expanding flow path with predominant portion of the tip end in a contracting flow path. Such a configuration can occur with a midpoint and trailing edge located in the contracting flow path. A center of gravity of a swept airflow member having spherical end shape can be located on a pivot axis of the airflow member. Divot depressions can be provided to permit concave flow path shapes.
