Abstract
An apparatus and method for assembling an inducer assembly for inducing a rotation on an airflow passing within a turbine engine. The inducer assembly can provide a volume of fluid from a compressor section to a turbine section of the engine. The inducer assembly can include the combination of separate segments to form an annular inducer.
Claims20
A turbine engine cooling air circuit comprising:
- an inducer assembly having a plurality of interconnected segments collectively forming an annular shape, wherein each segment of the plurality of segments includes a doublet, each doublet including two inducer-particle separator pairs, a first arm extending in a first circumferential direction, and a second arm extending in a second circumferential direction opposite of the first arm to route a cooling airflow;
- and
- a windage cover coupled to the inducer assembly to prevent the cooling airflow from bypassing the inducer assembly.
A turbine engine comprising:
- an engine core having a compressor section, combustor section and a turbine section in axial flow arrangement;
- an inducer assembly forming at least a portion of a cooling air circuit to route a cooling airflow among at least two of the sections of the engine core, the inducer assembly having a plurality of interconnected segments collectively forming an annular shape, wherein each segment of the plurality of segments includes a doublet, each doublet including two inducer-particle separator pairs, a first arm extending in a first circumferential direction, and a second arm extending in a second circumferential direction opposite of the first arm to route the cooling airflow;
- and
- a windage cover coupled to the inducer assembly to prevent the cooling airflow from bypassing the inducer assembly.
