Abstract
An aircraft engine cooling air system is configured to provide cooling air to turbine components. The system has an airflow path extending from a source of cooling air to the turbine components. A baffle is disposed in the airflow path upstream of the turbine components. The baffle has a filtering surface defining a plurality of filtering holes sized to trap particulate matter suspended in the cooling air. A bypass passage is fluidly connected to the source of cooling air and the turbine components in parallel with the baffle so as to allow airflow to the turbine components when the filtering holes of the baffle are clogged.
