DEVICES AND METHODS FOR GUIDING BLEED AIR IN A TURBOFAN ENGINE

Device and methods for guiding bleed air in a turbofan gas turbine engine are disclosed. The devices provided include louvers (302, 128) and baffles (304, 128) that guide bleed air toward a bypass duct (104) of the turbofan engine (100). The louvers (302, 128) and baffles (304, 128) have a geometric configuration that promotes desirable flow conditions and reduced energy loss.
