Claim 7:
8. A gas turbine engine, comprising:
a fan section configured to induce air from a surrounding environment into the gas turbine engine;
a compressor section in fluid communication with the fan section and configured to compress the air received from the fan section;
a combustor section in fluid communication with the compressor section and configured to ignite a fuel-air mixture to generate combustion gases;
a turbine section in fluid communication with the combustor section; and
a debris capture device to remove particulate matter from fluids associated with lubricating rotating components of the gas turbine engine, comprising:
an inlet pipe disposed substantially tangentially to an internal surface of a housing;
an outlet pipe; and
an oil filtration assembly, comprising:
the housing having a thickness defined between the internal surface of the housing and an external surface of the housing, the housing extending in an axial direction from a first end to a second end, the inlet pipe and the outlet pipe both disposed at the first end, the external surface defining an outer diameter of the housing, the outer diameter remaining constant from the first end to the second end;
a first filter having a first radially outer surface and a first radially inner surface, the first filter disposed in the housing, the first radially outer surface and the internal surface of the housing defining an outer annular flow passage;
a cavity disposed radially inward of the first filter, the cavity in fluid communication with the outer annular flow passage; and
a collection area disposed at the second end of the housing, the collection area configured to collect the particulate matter from an oil, wherein:
the inlet pipe is in fluid communication with the outer annular flow passage,
the outlet pipe is in fluid communication with the cavity to discharge the oil from the housing,
the oil is configured to flow radially from the outer annular flow passage through the first radially outer surface of the first filter and the first radially inner surface of the first filter into the cavity,
in response to injecting the oil substantially tangentially to the internal surface of the housing, the particulate matter is forced against the internal surface of the housing within the outer annular flow passage, and
the thickness of the housing gradually decreases towards the collection area.
