LOW PRESSURE TURBINE SHAFT MODULE - DESCRIPTION AND OPERATION
_____________________________________________________________
1. General
_______
A. The low pressure turbine (LPT) shaft module connects the fan shaft with the LPT rotor (Fig. 1). It is composed of the LPT shaft, LPT stub shaft, center vent tube and center vent tube rear extension duct. The aft end of the LPT shaft is supported by the No. 5 bearing; its forward end is coupled with the fan shaft. The LPT shaft has two functions: coupling the fan booster rotor with the LPT rotor and providing for high pressure turbine rear support through the No. 4 bearing. In addition, the LPT shaft houses the center vent tube of the forward and aft engine sumps.
