Abstract
A gas turbine engine includes a fan operable for delivering air into a bypass duct. The fan is also operable for delivering air into a core engine housing. The core engine housing encloses a compressor, a combustor and a turbine section. The core engine housing has an upstream end defining a separation point between the bypass duct and the core engine housing. An air separation device is adjacent the upstream end. The air separation device includes a baffle and an opposed louver. The baffle and louver together are structured for defining an airflow path to guide air adjacent the upstream end with a radially outward and axially downstream components. There are baffle ribs on the baffle facing opposed louver ribs on the louver, with at least some of the louver ribs being circumferentially offset from the baffle ribs.
