An analytical study in computer-aided vehicle design is presented. The vehicle under study is the Unlimited Competition Racing Hydroplane, and the design objective is to obtain maximum lift/drag ratio in addition to adequate pitch plane stability. After discussion of the design concept, the mathematical model used to represent the aerodynamics and hydrodynamics of the configuration is developed. The mathematical model is then programmed for solution on a digital computer and an optimization study is performed. It is concluded that a tentative preliminary configuration is obtained through computer-aided design, but that the complexity of the concept will require further tow tank and wind tunnel model tests.

Underwater vehicles present some difficult and very particular control system design problems. These are often the result of nonlinear dynamics and uncertain models, as well as the presence of sometimes unforeseeable environmental disturbances that are difficult to measure or estimate. Autonomous Underwater Vehicles: Modeling, Control Design, and Simulation outlines a novel approach to help readers develop models to simulate feedback controllers for motion planning and design. The book combines useful information on both kinematic and dynamic nonlinear feedback control models, providing simulation results and other essential information, giving readers a truly unique and all-encompassing new perspective on design. Includes MATLAB® Simulations to Illustrate Concepts and Enhance Understanding Starting with an introductory overview, the book offers examples of underwater vehicle construction, exploring kinematic fundamentals, problem formulation, and controllability, among other key topics. Particularly valuable to researchers is the book’s detailed coverage of mathematical analysis as it applies to controllability, motion planning, feedback, modeling, and other concepts involved in nonlinear control design. Throughout, the authors reinforce the implicit goal in underwater vehicle design—to stabilize and make the vehicle follow a trajectory precisely. Fundamentally nonlinear in nature, the dynamics of AUVs present a difficult control system design problem which cannot be easily accommodated by traditional linear design methodologies. The results presented here can be extended to obtain advanced control strategies and design schemes not only for autonomous underwater vehicles but also for other similar problems in the area of nonlinear control.

The idea of editing a book on modern software architectures and tools for CAPE (Computer Aided Process Engineering) came about when the editors of this volume realized that existing titles relating to CAPE did not include references to the design and development of CAPE software. Scientific software is needed to solve CAPE related problems by industry/academia for research and development, for education and training and much more. There are increasing demands for CAPE software to be versatile, flexible, efficient, and reliable. This means that the role of software architecture is also gaining increasing importance. Software architecture needs to reconcile the objectives of the software; the framework defined by the CAPE methods; the computational algorithms; and the user needs and tools (other software) that help to develop the CAPE software. The object of this book is to bring to the reader, the software side of the story with respect to computer aided process engineering.

With a renewed focus on the Asia-Pacific region, the United States Navy will increasingly rely on high-endurance unmanned underwater vehicles (UUVs) to support successful operations in a challenging threat environment. Undoubtedly, this naval strategy will necessitate versatile UUV systems that fulfill a broad spectrum of customer-generated requirements. This thesis presents a unique approach to the conceptual design process for UUVs, thereby allowing strategic decision-makers to rapidly explore a given design space. The proposed MA TLAB-based conceptual design program features five primary modules: a mission module, a hull module, a resistance module, a battery module, and a pressure vessel module. The final concept design results from an iterative process that considers the displacement, interior volume, and exterior volume of the total UUV system. To validate the proposed design algorithm, the author applied the best practices of modern naval architecture, marine engineering, ocean engineering, systems engineering, and submersible design. Model test data and computational fluid dynamics (CFD) software were used to validate the empirical equations selected for the resistance module. The pressure vessel module, including a genetic algorithm to generate viable scantlings, was validated by a consideration of manually optimized pressure vessel designs. Ultimately, this thesis demonstrates the sufficiency, reliability, and versatility of the proposed conceptual design program for UUVs.
