An exhaust eductor for a gas turbine engine comprises: an engine exhaust chamber with an exhaust chamber inlet that receives engine exhaust from the gas turbine engine and an exhaust chamber outlet that discharges the engine exhaust to establish an exhaust gas flow through the engine exhaust chamber; an air chamber with an air inlet that receives ambient air external to the gas turbine engine; and a mixing baffle that couples the air chamber to the engine exhaust chamber, comprising a first side adjacent the air chamber, a second side adjacent the exhaust chamber, multiple apertures through the mixing baffle that extend from the first side to the second side of the mixing baffle, each aperture having a corresponding canopy that extends from an upstream end of the aperture along the second side of the mixing baffle into the exhaust gas flow for at least a portion of the length of the aperture, to establish an air flow from the air inlet of the air chamber into the exhaust gas flow. |
