Components and arrangement thereof for Brayton-Rankine turbine

摘要

An engine consisting of an open Brayton cycle gas turbine mechanically as well as thermodynamically integrated with a closed cycle Rankine turbine engine is disclosed. The engine heat exchangers, including Rankine vapor generator, regenerator and condenser, are of annular configuration and are concentric with the axis of rotation of the turbomachinery components. A cooling fan is mounted coaxially with the condenser for improved cooling effectiveness. The engine components also are balanced around the gearbox for improved installation and use.
