摘要： An oil scavenge system includes a tangential scavenge scoop and a settling area adjacent thereto which separately communicate with a duct which feeds oil into an oil flow path and back to an oil sump. A shield is mounted over the settling area to at least partially shield the collecting liquid oil from interfacial shear. A multiple of apertures are located through the shield to permit oil flow through the shield and into the duct. The scavenge scoop forms a partition which separates the duct into a first portion and a second portion. The first portion processes upstream air/oil mixture that is captured by the tangential scoop while the second portion receives the oil collected in the settling area.

摘要： Hot spots in the first stage turbine nozzles of small and medium sized engines are eliminated by spinning the nozzle assembly which consists of an annular hub circumscribed by a nozzle diaphragm having an inner and outer shroud ring between which are a multiplicity of symmetrically positioned vanes of airfoil design. Power to turn the nozzle assembly is obtained by connecting it to a rotary-type, vaned diffuser stage which lies in radial alignment with the impeller of the engine compressor. The rotary diffuser and nozzle combination is configured to turn at 50-1,000 rpm enabling the combined assembly to be mounted on unlubricated ceramic bearings.
