The complex mechanical gear trains and lubrication systems of conventional engine configurations are eliminated by using combinations of hydrodynamic air foil bearings, hydrodynamic solid geometry carbon seals/bearings, magnetic bearings, and electrical starter/generators that can also act as bearings to support the high speed shafts of gas turbine engines. The various bearing types and the starter/generators are arranged in such a way as to share peak loads experienced by the engine shaft during maximum aircraft maneuvers. This results in a minimal bear...
1. A rotor comprising:at least a first rotor; an air foil bearing supporting a first end of said first rotor; and a hydrodynamic carbon bearing/seal providing additional support to said first rotor and sealing a bearing compartment of said air foil bearing, thereby allowing an increased internal operating pressure of said air foil bearing, and hence, increased load capacity of said air foil bearing, as compared to said air foil bearing without said hydrodynamic carbon bearing/seal. 2. The rotor according to claim 1, wherein said hydrodynamic carbon beari...
