Abstract
An exhaust system of a gas turbine engine includes an exhaust duct, and a venturi drainage device that drains fluid collected in the exhaust duct. The venturi drainage device includes an inlet in fluid communication with the exhaust duct. The venturi drainage device operates in an entrain mode when a flight condition occurs during operating of the gas turbine engine and operates in a drain mode when the gas turbine engine is not operating to drain the fluid from the exhaust duct.
