Abstract
A cooling system for a compressor casing of an turbofan engine includes a cooling conduit extending between an inlet in fluid communication with a bypass duct of the turbofan engine and an outlet in fluid communication with an outer surface of the compressor casing. A shroud of the compressor is mounted to the compressor casing. A protrusion is disposed about an opening to the inlet and protrudes radially outwardly into the bypass duct A valve in selective fluid communication with the inlet of the cooling conduit is operable to selectively inject a flow of high pressure air from a high pressure air source towards the inlet of the cooling conduit to modulate a flow of bypass air entering the cooling conduit.
