Methods and apparatus for supplying air to gas turbine engines
First Claim
1. A method for supplying air to a gas turbine engine positioned within a housing including an air inlet module, ail exhaust gas module, and a duct, the inlet module connecting an inlet of the gas turbine engine to the atmosphere, the exhaust gas module including a first conduit and a second conduit, the first conduit within the second conduit and connecting an exhaust of the gas turbine engine to the atmosphere, the second conduit open only to the atmosphere, the duct connected to the exhaust gas module second conduit anti in flow communication with the gas turbine engine inlet, said method comprising:
- operating the gas turbine engine within the module such that exhaust airflow exits the engine through the exhaust module first conduit; and
supplying air to the gas turbine engine inlet from the exhaust module second conduit through the duct.

Abstract
A gas turbine engine assembly including a gas turbine engine mounted within a module and including an inlet in flow communication with a module inlet area and a module exhaust area is described. The turbine engine also includes an exhaust, and is mounted within an engine area between the module inlet and exhaust areas. More specifically, the gas turbine engine is mounted such that the engine exhaust is in flow communication with the module exhaust area. Because the module also includes a secondary supply duct, the gas turbine engine is in flow communication with the module inlet and exhaust areas.
