ABSTRACT:
A gas turbine engine (10) comprising a first turbine (19) and a first compressor (13) mounted on a first shaft (26) and a bearing arrangement (52, 34) supporting the shaft (26), the bearing arrangement is subject to a total end load and comprises a fixed bearing (34), a load share bearing (52) and a bearing end load management system (50) that is capable of applying a variable load to the load share bearing to manage total end load between the bearings. The bearing end load management system comprises a static diaphragm (54) that defines part of a chamber (56) and that is coupled to the load share bearing whereby increased pressurization of the chamber loads the diaphragm which in turn increases the proportion of the total end load on the load share bearing.
