ABSTRACT:
A centrifugal particle separator removes particles such as dust particles from a compressed airflow prior to reaching and cooling the turbine blades of a turbine engine. A particle separator structure defines a plurality of inward-facing pockets which are separated by pocket dividers defining an airflow path having a diameter that decreases from the entrance to the exit. A centrifugal force created by the rotating centrifugal particle separator assembly causes particles to collect within the plurality of pockets and the remaining compressed air is provided to cool the turbine blades. The decreasing diameter of the airflow path forces the airflow with particles to accelerate to a rotational velocity greater than that of the rotating particle separator by conservation of momentum.
