Abstract
A turbo-compounded engine includes a piston engine connected to drive a propulsor. An outlet of the piston engine is operable to connect products of combustion from the piston engine to pass over a turbine. The turbine is connected to drive a turbine shaft also providing rotation to the propulsor. An outlet of the turbine is connected into an exhaust duct configured to exhaust the products of combustion. The exhaust duct is provided with an exhaust duct outer wall defining an exhaust chamber, and a further cooling air outer wall is positioned outwardly of the exhaust duct. Struts connect a cooling chamber between the cooling air outer wall and the exhaust duct outer wall into a center bullet. The center bullet has a downstream end for directing the cooling air into the exhaust chamber at a location upstream of a downstream end of the exhaust duct outer wall.
