Concept Exploration Process, Methodology and Design Tools for Teaching Naval Ship Design
Abstract
Approved for Public ReleaseThis project will develop a toolbox of Naval Ship Concept Exploration and Development tools, educational,materials and curricula for use at Virginia Tech, the MIT 2N Program and other universities for teaching naval ship design. Although, process and methods will be the focus of this work, it will use Model Center, Paramarine or LEAPS (w/o RSDE hence Distro A), MATLAB, and Excel as core software. This software is effective, readily, if not already, available in universities, fully Distro A, and eas,ily accessible to students with a modest learning curve. The research and development will coordinate closely with MIT 2N, NSWCCD Co,de 823 and NAVSEA 05D1 to ensure that the tools best support transition to the USN?s ongoing design tool effort and need for ship de,sign education without crossing the line into limited distribution materials.A full system of systems approach will be used to achie,ve the objectives of this proposal including: combat systems, power and energy systems; hullform; subdivision and arrangements for o,perability, survivability and fight-thru; and design assessment through direct modeling and interface with Operational Situations (O,PSITS) at the ship and force levels based on a Design Reference Mission. It will use an ?inside-out meets outside-in? design approac,h, which after sufficient exploration and definition of both problems, are integrated using a multi-objective, multi-disciplinary op,timization that searches a large design space and among other things assesses the feasibly of alternative inside and outside approac,hes and combinations.The basic framework that integrates and underlies our total a,architectures: logical, physical and operational. We believe that each of these architectures are necessary components of the whole,and must be considered explicitly and quantitatively in order to teach and perform naval ship design. Each of the architectures are,supported by what we call Ship Behavior Interaction Models (SBIMs) as well as the fundamental models and theory that support the ind,ividual system engineering and science such as hull form hydrostatics, hydrodynamics, seakeeping, power and energy, combat systems a,nd ship vulnerability/recoverability. All of these components and architectures are tied together and supported by a ship synthesis,model, an interactive design environment (Model Center) and ship physical architecture tools, currently Rhino/ORCA3D, but transition,ing to Paramarine. We expect that Paramarine will allow us to better explore physical architecture, general and machinery arrangemen,ts, and ensure feasibility, particularly for new and emerging technologies and components for which existing synthesis model paramet,rics for space and weight may not be applicable. Unique to our systems engineering approach is the ability to interface ship systems, directly with operational situations in time-based scenarios including the possibility for weapon hits, system damage, reconfigurat,ion and fight-thru, and to optimize all combat, power and energy systems simultaneously and automatically. We have developed our AFO, and related DAFO network methods that optimize system logical, physical and operational architectures to improve, refine and assess,n open-source papers, theses and dissertations.The proposal fully supports objectives of the ONR Naval Engineering Technology Area i,ncluding education and outreach in naval engineering, the health of critical naval S&T tools, processes and analyses, and the nation,al pipeline of new researchers, engineers and faculty in naval architecture and marine engineering.
