Abstract: A temperature measurement system for a gas turbine engine, the gas turbine engine including, in axial flow sequence, a compressor section, a combustor section having plural fuel spray nozzles, and a turbine section. The temperature measurement system includes one or more optical thermometers, each optical thermometer configured to measure the temperature of a component washed by the working gas of the engine, the or each component being in the combustor section or the turbine section at a first position along the axis of the engine.

Abstract: A method for manufacturing a fuel spray nozzle for a gas turbine engine includes forming a first section of the fuel spray nozzle by additive layer manufacturing. The first section includes a main chamber and internal passageways. The method includes forming a second section of the fuel spray nozzle by additive layer manufacturing on the first section. The second section includes a metering feature disposed in fluid communication with one of the internal passageways of the first section. The method includes modifying the metering feature of the second section by a first subtractive manufacturing process to obtain a desired diameter of the metering feature and/or a desired surface roughness of the metering feature. The method includes forming a third section of the fuel spray nozzle by additive layer manufacturing on the second section. The third section includes a deflector and a spin chamber.
