A conceptual design was made of an 80000-shp fossil-fired closed-cycle helium turbine system for naval propulsion applications. Various oil-fired heater and power conversion system configurations were investigated, and a reference system was selected based on a trade-off between the system performance and the component size and weight characteristics which would yield the maximum payload capability for the ship type considered. The conceptual design of major components was made based on the parametric design results identified from a comprehensive computer program incorporating extensive past design experiences. The conceptual design drawing for the propulsion engine is presented, and a preliminary propulsion system lyout applicable to a conceptual high-speed destroyer is shown. The analysis indicates that no severe integration problem is anticipated for this typ propulsion engine for lightweight ship propulsion applications. (Wassmann)
