Water cooled automotive gas turbine engine
The rotary disc, regenerative type automotive gas turbine engine has a water cooled block for supplying hot water to a cab heater core and for supporting a gasifier spool and a power turbine spool within a core section of the block which receives high pressure air from a rotary regenerator matrix disc for flow to a combustor for supplying motive fluid to a gasifier turbine and power turbine with exhaust flow directed from the core section through the regenerator matrix disc and wherein the water cooled block includes an integral planar surface theron defining a reference plane for the rotary regenerator matrix with the high pressure inlet air and low pressure exhaust gas being directed therethrough for heating the inlet air and wherein the block further includes a water coolant filled passage therethrough in surrounding relationship to the power turbine to act as a containment mass therearound; the water coolant filled passage being located in close proximity to the planar surface defining the reference plane for the generator matrix; said passage also being located adjacent drive components for the regenerator to reduce thermal distortion of the reference plane and to cool regenerator drive components during engine operations.
