Abstract
A component for a turbine engine includes a body having an outer surface confronting a combustion air flow path and defining an interior, as well as a first cooling passage having at least a portion supplying cooling air to the interior of the body. The component also includes a cyclone separator having a cooling air inlet, a clean air outlet, and a dirty air outlet.
Claims19
A component for a turbine engine comprising:
- a body having an outer surface confronting a combustion air flow path and defining an interior;
- a first cooling passage having at least a portion supplying cooling air to the interior of the body;
- a second cooling passage having at least a portion supplying cooling air to the interior of the body and fluidly separated from the first cooling passage;
- a scavenge passage fluidly separated from the second cooling passage;
- and
- a first cyclone separator having a cooling air inlet, a clean air outlet fluidly coupled to the first cooling passage, and a dirty air outlet fluidly coupled to the scavenge passage;
- wherein the dirty air outlet of the first cyclone separator is fluidly separated from the interior of the body.

A component for a turbine engine, comprising:
- an airfoil body with an outer wall bounding an interior and extending axially between a leading edge and a trailing edge to define a chord-wise direction, and also extending between a root and a tip to define a span-wise direction;
- a first cooling passage having at least a portion supplying cooling air to the interior of the airfoil body;
- a second cooling passage having at least a portion supplying cooling air to the interior of the airfoil body and fluidly separated from the first cooling passage;
- a scavenge passage;
- and
- a cyclone separator having a cooling air inlet, a clean air outlet fluidly coupled to the second cooling passage, and a dirty air outlet fluidly coupled to the scavenge passage, wherein the dirty air outlet is fluidly separated from the interior of the airfoil body.
3 more elements
A method of cooling a component in a turbine engine, the method comprising:
- flowing a supply of cooling air to the component;
- directing a first portion of the supply of cooling air to a cyclone separator located within the component to clean the first portion of the supply of cooling air to form a cleaned first portion, and to direct dirty air to a scavenge passage at a dirty air outlet, where the dirty air outlet is fluidly separated from the cooling passage within the component;
- flowing the cleaned first portion through a first supply conduit to the cooling passage within the component;
- and
- flowing a second portion of the supply of cooling air through a second supply conduit to the cooling passage, the second supply conduit being fluidly separated from the cyclone separator.
