This book was released on 1977 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of system studies as part of a comprehensive study program to evaluate the technological and economic feasibility of utilizing open- and closed-cycle gas turbines integrated with fossil or nuclear heat sources for providing advanced lightweight propulsion power for future Navy capital ship applications. The level of technology considered is that judged by the Contractor to be available during the 1990's. Naval ship types which could benefit from implementing lightweight propulsion systems were selected and characterized, and performance and weight characteristics for selected propulsion machinery components were estimated. Turbomachinery technologies applicable to naval ship propulsion were reviewed, and future advances in crucial technical areas were projected. Eight reference installed power levels between 40,000 and 300,000 shp applicable to the ship types considered were selected. Basic propulsion system arrangements compatible with component capabilities were identified. From the huge number of possible combinations of propulsion system components, arrangements, and power levels for different ship types, a manageable number of practical cases were selected by use of a matrix screening process and subjected to detailed study.

This book was released on 1979 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: This executive summary report presents the major results of a comprehensive study program to evaluate the technological and economic feasibility of utilizing open- and closed-cycle gas turbines to provide lightweight propulsion power for future Navy surface ship applications. The level of technology considered in this study is that judged by the Contractor to be available during the 1990's. Naval ship types which could benefit from implementing lightweight propulsion systems were identified and characterized, and applicable propulsion system configurations and power levels compatible with component capabilities were selected. Extensive parametric analyses were made of the performance, weight, and cost characteristics for the baseline propulsion systems, from which the total propulsion-system-plus-fuel weight was then estimated. The payload capabilities and endurance limitations with open- and closed-cycle gas turbine propulsion systems for selected ship types are presented.

Download or read book Naval Ship Propulsion and Electric Power Systems Selection for Optimal Fuel Consumption written by Emmanouil Sarris and published by . This book was released on 2011 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although propulsion and electric power systems selection is an important part of naval ship design, respective decisions often have to be made without detailed ship knowledge (resistance, propulsors, etc.). Propulsion and electric power systems have always had to satisfy speed and ship-service power requirements. Nowadays, increasing fuel costs are moving such decisions towards more fuel-efficient solutions. Unlike commercial ships, naval ships operate in a variety of speeds and electric loads, making fuel consumption optimization challenging. This thesis develops a flexible decision support tool in Matlab® environment, which identifies the propulsion and ship-service power generation systems configuration that minimizes fuel consumption for any ship based on its operating profile. Mechanical-driven propulsion systems with or without propulsion derived ship-service power generation, separate ship-service systems and integrated power systems are analyzed. Modeling includes hull resistance using the Holtrop-Mennen method requiring only basic hull geometry information, propeller efficiencies using the Wageningen B series and transmission and prime movers fuel efficiencies. Propulsion and ship-service power generation systems configuration is optimized using the genetic algorithm. US Navy's Advanced Surface Ship Evaluation Tool (ASSET) model for the DDG-51 Flight I destroyer was used for modeling validation. Optimal fuel consumption results are compared against the existing configuration for the DDG-51 Flight I destroyer using a representative operating profile.
Download or read book An Impact Analysis of Superconducting Electrical Propulsion Systems on Naval Ship Design written by William Joe York and published by . This book was released on 1979 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three different proposed propulsion systems which incorporate superconducting electric machines are described. Two of these systems utilize a propulsion system integrated ship service electrical system. A ship synthesis computer model is used to determine the gross characteristics, detailed weight and volumes, maximum sustained speed, and endurance fuel requirements for each proposed design. Each of the designs is compared to a baseline ship, the FFG-7, to determine the impact of a superconducting propulsion system on gross characteristics, maximum sustained speed, endurance fuel, general arrangements, payload, vulnerability/survivability, risk, maintenance, and cost. Final comparison of the proposed designs shows a 31% reduction in propulsion machinery weight for all candidates. The two superconducting/integrated designs show a 61% reduction in electrical machinery weight, a 6% reduction in total required volume, a 10% reduction in full load displacement, a 7% increase in maximum sustained speed, and an 8% reduction in fuel.

Available in PDF, EPUB and Kindle. Book excerpt: The effort is concerned with the application of graphite/epoxy and graphite/polyimide composite materials in the design of both a conaxial compressor and a centrifugal compressor. The first part of the program involved the study of a composite conaxial compressor to determine the fabrication and structural feasibility of producing such a compressor. This composite compressor would be capable of 2000 feet per second tip speeds and would be applicable to small engines. The second part of the program involved the study of a centrifugal compressor that was to be constructed of advanced composite materials substituted on a functional-replacement basis with the current titanium material with the objective of arriving at a cost-competitive component. Structurally feasible designs for both the coaxial and centrifugal components were developed under the constraints set in the program. It is doubtful that composites can be utilized on a cost-competitive basis in the centrifugal compressor application unless the economics of high-volume production can be utilized to justify the cost of the necessary specialized automated equipment. It is recommended that future effort be directed toward the development of the composite conaxial compressor, since a major advance in axial compressor technology is possible. (Author, modified-PL).
