Abstract
A component for a turbine engine includes a body having a wall at least partially defining an interior and separating a combustion air flow path from a cooling air flow path. The component also includes at least one fluid inlet supplying cooling air to the interior of the body, as well as a cyclone separator.
Claims20
A turbine engine comprising:
- a core comprising a compressor section, a combustion section, and a turbine section, which are axially arranged to define a combustion air flow path passing through the core;
- a casing surrounding the core;
- an annulus defined between the core and the casing;
- a plurality of components with corresponding fluid inlets circumferentially spaced about the annulus;
- a cooling air flow path passing through at least one of the core and the casing;
- and
- a set of cyclone separators within the annulus, each cyclone separator in the set having a cooling air inlet fluidly coupled to the cooling air flow path, a clean air outlet, and a dirty air outlet,
- wherein the set of cyclone separators includes groups of at least two cyclone separators, each in the group having their clean air outlets fluidly coupled to a common fluid inlet.
A component for a turbine engine generating a combustion air flow path and providing a cooling air flow path, the component comprising:
- a body having a wall extending into the combustion air flow path and at least partially defining an interior and the wall separating the combustion air flow path from the cooling air flow path;
- at least one fluid inlet supplying cooling air to the interior of the body;
- and
- at least two cyclone separators each having a cooling air inlet fluidly coupled to the cooling air flow path, a clean air outlet fluidly coupled to the at least one fluid inlet, and a dirty air outlet.
A method of cooling a component for a turbine engine generating a hot airflow and providing a cooling airflow, with the component confronting the hot airflow and including a wall at least partially defining an interior receiving the cooling airflow, the method comprising:
- flowing cooling air through a first cyclone separator located within the component to define a cleaned first supply of cooling air;
- flowing cooling air through a second cyclone separator located within the same component to define a cleaned second supply of cooling air;
- and
- directing the cleaned first and second supplies of cooling air to a common interior cooling passage within the interior for the same component.
