SYSTEM AND METHOD FOR COMBINING COMPRESSOR BLEED FLOW AND VENTILATION FLOW OF GAS TURBINE ENGINE

A flow combiner (12) is provided for a gas turbine engine (50). The flow combiner (12) includes an outlet duct (14), a compressor bleed inlet duct (16) coupled to the outlet duct (14), and a ventilation inlet duct (18) coupled to the outlet duct (14). The compressor bleed inlet duct (16) is configured to receive a bleed flow (28) from a compressor (56) of the gas turbine engine (50). The ventilation inlet duct (18) is configured to receive a ventilation flow (36) from an enclosure (54) surrounding the gas turbine engine (50). The bleed flow (28) and the ventilation flow (36) are combined as an outlet flow through the outlet duct (14).
