The proposed work will determine the feasibility of achieving direct reversal of the power turbine section of a marine gas turbine of the class and type used for main propulsion in u.s. navy surface combat ant ships. A through literature, patent, and technical information search will be made to determine the state-of-the-art, experience, and technology of reversing gas turbines here and abroad. Contacts with leading gas turbine manufactures here and abroad, leading naval architects, and naval r & d agencies (y'ard, etc.) Will be made to supplement the survey. Conceptual designs will be developed, analyzed refined, and detailed analyses made of the most promising concepts with respect to the intended marine propulsion environment. Aerodynamic, hydrodynamic and mechanical solutions will be considered as long as they fall within the criteria establilshed for naval propulsion applications.
