ABSTRACT:
An integrated turbine and generator includes a power turbine having counter-rotating outer and inner rotor blades extending from respective outer and inner rotors. The outer and inner rotors are supported by stationary front and rear frames. At least one electrical generator includes a field core for creating magnetic poles which is disposed coaxially with an armature for generating electrical power upon relative rotation therebetween. The field core and the armature are disposed coaxially with the outer rotor and radially outwardly therefrom, with one of the field core or armature being fixedly joined to the outer rotor for rotation therewith, and the other one thereof being fixedly joined to the front and rear frames. In a preferred embodiment, a tractor piston is joined to the inner rotor and a pusher piston is joined to the outer rotor and both provided with steam under pressure for generating forward thrust forces thereagainst for balancing aft thrust forces from the outer and inner blades carried through front and rear thrust bearings to the front and rear frames.
