Abstract: A gas turbine engine fuel nozzle comprises a spray tip defining a fuel exit passage therethrough that extends along a central axis. The fuel exit passage has an exit orifice aligned with the central axis. The exit orifice is circumscribed by an inner annular surface. The inner annular surface has a spherically-convex profile in cross-section, the profile being constant around the circumference of the inner annular surface.

Abstract: A method of accessing a nozzle tip assembly of a gas turbine engine fuel nozzle is disclosed. The fuel nozzle has a stem and a heat shield enclosing at least part of the stem. The nozzle tip assembly is disposed within an inner cavity of the stem. The method includes forming an opening in at least the heat shield of the fuel nozzle, the opening providing access to the inner cavity of the stem via a first end thereof. The first end of the cavity is positioned opposite to a fuel nozzle exit from which fuel is conveyed from the fuel nozzle. The method includes accessing the nozzle tip assembly in the inner cavity via the opening. The method includes closing the opening after accessing the nozzle tip assembly.
