ABSTRACT:
A pusher turboprop engine is provided with an interior exhaust duct structure which directs the hot turbine gases through and out of the engine nacelle and around the rear spinner which surrounds the propeller hub. The spinner supports blade-shaped shields which protect the roots of the propeller blades from the hot exhaust gasses.
