Abstract
A secondary air system for an aircraft engine comprises an air flow path communicating between a source of pressurized cooling air and an air consuming component. A filtering baffle is disposed in the air flow path upstream from the air consuming component. The filtering baffle has a monolithic body at least partly made of a cellular material, the cellular material including a non-stochastic lattice structure having a plurality of cells arranged in an ordered, repeating manner for trapping particulate matter contained in a flow of contaminated air.
