3KSES Producibility Improvement Study - Propulsion and Lift Systems Summary Report (0108)
This summary report documents tasks for the 3000-Ton Surface Effect Ship Producibility Improvement Plan. The principal objective is to identify propulsion and lift system concepts that will impart to the improved producibility SES, maximized performance and economy of operation consistent with minimized risk. The effort supports the ship design concept development reported in the 3KSES Producibility Study, Ship Characteristics and Performance Report (Preliminary), 26 Jun 81.Two basic propulsion/lift systems are identified for ships in the nominal displacement range of 1000 to 1800 LT established for the study. There are three appendices: "Appendix A -- Propulsor Studies" documents work to select the optimum propeller system for the various sizes of MDC* ship. Technical descriptions are given. Sizing and performance calculations are presented. A propeller performance computer program and results are described. Drive shafting design parameters are outlined. "Appendix B -- Propulsion Machinery Configuration" addresses arrangements for the ship main propulsion and lift machinery. Technical descriptions are given. Layouts are presented. Reduction gearing and CODOG arrangements are examined in detail. Cost data and recommended sources for all machinery including lift are furnished. "Appendix C -- Lift Machinery Configuration" presents machinery selections, arrangements, and performance for the various ships. All three appendices discuss Technical risk, reliability, maintainability, and producibility.
* "MDC" stood for a Medium Displacement Combatant (1000-1500 Lt)
