| 摘要 |
A propulsion system (10) includes a first row of propeller blades (16A) which rotate about an axis, an annular cooling flow nozzle (18) about an axis, the annular cooling flow nozzle upstream of the first row of propeller blades, and an annular exhaust nozzle (14) about an axis radially outboard of the annular cooling flow nozzle, the annular exhaust nozzle upstream of the first row of propeller blades.
A method of directing an exhaust flow from a propulsion system is also disclosed.
