Abstract: A fuel nozzle for a gas turbine engine is constructed with two major castings where one is the support (10) and the other is the head (12), both welded together adjacent the fuel orifice plate (24). The fuel passage (14) is cast into the support (10) providing a smooth radius (16) from the radial to axial flow path and a smooth transition from the circular to the annular cross section. This configuration allows dimension control over the filming lip (30) and other critical dimensions of the nozzle.
