Abstract
A rotor shaft that drives a load and is supported by a plurality of bearings includes a first bearing to support a distal end of the shaft, a second bearing to support a distal end of the load, and a third bearing to support both proximal ends of the shaft and the load in order to dynamically uncouple the load from the rotor shaft and to eliminate a fourth bearing of the prior art. The invention is also used in a small gas turbine engine in which the turbine shaft is connected to an electric generator, and the third or middle bearing supports the proximal ends of the generator and the rotor shaft to dynamically uncouple the turbine shaft from the generator rotor.
