Methods and apparatus for exhausting gases from gas turbine engines

A gas turbine engine assembly comprising:

• a module comprising an inlet area, an engine area, and an exhaust area, said engine area extending between said inlet and exhaust areas to define a cavity, said module exhaust area comprising an exhaust duct and an outlet extending in flow communication from said exhaust duct;
• a gas turbine engine within said module cavity, said engine comprising an inlet and an exhaust, said turbine engine exhaust adjacent said module exhaust area, said module exhaust duct for routing exhaust gases discharged from said gas turbine engine exhaust substantially perpendicularly from said gas turbine engine, said exhaust area outlet for routing exhaust gases discharged from said exhaust duct in direction that is at least ninety degrees offset with respect to exhaust gases flowing within said exhaust duct;
• and
• a cooling system comprising an inlet and an exhaust, said inlet for supplying cooling fluid into said module engine area external said gas turbine engine, said cooling system exhaust for discharging cooling fluid from said module engine area, said module exhaust area concentrically disposed within said cooling system exhaust.
