| 摘要 |
The invention relates to an engine for an aircraft. The engine includes an engine housing having a drive shaft and a power output shaft. The power output shaft and the drive shaft are separately journalled within the engine housing. The power output shaft includes a propeller at a front end for providing propulsive thrust for the aircraft. The aft end of the power output shaft extends aft of the engine housing. The drive shaft is rotatably coupled to the aft end of the power output shaft by a gear train located outside and aft of the engine housing. The engine provides bearings which solidly support the power output shaft over a substantial portion of its length. This arrangement significantly reduces the loads which would be applied to the drive shaft and other engine components, and therefore, increases the service life of these components.
