AIRCRAFT PROPULSION SYSTEM WITH PROPELLER AND COOLING FAN

An aircraft propulsion system (10) comprises an engine (12), a propeller drive shaft (14) drivingly engaged with the engine (12), a propeller (16) for propelling an aircraft and a fan (22) driving cooling air along a flow path in thermal communication with the engine (12). The engine (12) may be an internal combustion engine or other engine type having heat rejection requirements and the fan (22) may facilitate cooling of the engine (12). The propulsion system may have a pusher configuration.
