A lubrication system is provided for delivering a lubricant to a plurality of nozzles. The lubrication system includes a reservoir for the lubricant; a pump fluidly coupled to the reservoir and configured to remove a flow of the lubricant from the reservoir; a lubrication sensor positioned between the pump and the plurality of nozzles and configured to detect a blockage in the plurality of nozzles and to generate a blockage signal when the blockage is detected; and an indicator coupled to the lubrication sensor and configured to generate a warning based on the blockage signal from the lubrication sensor.

A first-stage turbine that is adapted for receiving high energy air directly from a combustion chamber in a gas turbine engine auxiliary power unit includes a disk formed from a first alloy and having an outer surface, and a unitary blade wheel formed from a second alloy that is different than the first alloy. The unitary blade wheel includes an annular member having an inner surface that is joined to the disk, and blades that are integrally formed with the annular member.

A component for a gas turbine engine having an engine axis includes a rotor disk and a plurality of airfoils. The rotor disk comprises a web and a rim. The web has a first outer surface at least partially defining a plurality of holes and a plurality of slots. Each of the plurality of slots extends from a corresponding one of the plurality of holes and forms a first angle with the engine axis at the point of intersection with the corresponding one of the plurality of holes. The rim has a second outer surface also at least partially defining the plurality of slots. Each of the plurality of slots forms a second angle with the engine axis at the second outer surface, the second angle being different from the first angle. Each of the plurality of airfoils extends from the second outer surface.

An auxiliary power unit (APU) includes a rotary fuel slinger, and a single-spool, two-stage turbine. The rotary fuel slinger receives a rotational drive force from the turbine, and a supply of fuel from a fuel source. The rotary fuel slinger injects the fuel into a combustor as a continuous 'fuel sheet.' As a result, fuel mixing and atomization inside the combustor is improved, which reduces emissions and pattern factor, which in turn increases turbine life.
