Abstract
A cyclonic particle separator may include a housing including a cylindrical sidewall having a plurality of flow entry ports. A cover member closes a first end of the cylindrical sidewall, and a mounting member having a flow exit opening defined therethrough is at a second end of the cylindrical sidewall. At least one particle exit passage is defined in the housing. Each of the plurality of flow entry ports includes a flow directing surface angled to direct a gas flow from upstream of the housing to enter the housing in a tangential direction relative to the cylindrical sidewall, causing a cyclone vortex. The cyclone vortex acts to separate particles from the gas flow.

A cyclonic particle separator, comprising:
- a housing including:
- a cylindrical sidewall having a plurality of flow entry ports defined therethrough,
- a cover member closing a first end of the cylindrical sidewall, and
- a mounting member at a second end of the cylindrical sidewall and having a flow exit opening defined therethrough;
- and
- at least one particle exit passage defined in the housing
- an annular body located within the cylindrical sidewall, the annular body defining a cyclonic separating chamber between an interior of the cylindrical sidewall and the annular body;
- a wall extending around the flow exit opening to define an annular particle trap with the cylindrical sidewall and the annular body, wherein the at least one particle exit passage includes a first particle exit passage in fluid communication with the annular particle trap;
- and
- wherein each of the plurality of flow entry ports includes a flow directing surface angled to direct a gas flow from upstream of the housing to enter the housing in a tangential direction relative to the cylindrical sidewall, causing a cyclone vortex within the housing, and
- wherein the housing is operatively mounted to one of an inner endwall and an outer endwall of a turbine vane by the mounting member.
