Design And Operational Performance Of Manned Submersibles

This book investigates Reliability-based Multidisciplinary Design Optimization (RBMDO) theory and its application in the design of deep manned submersibles (DMSs). Multidisciplinary Design Optimization (MDO) is an effective design method for large engineering systems like aircraft, warships, and satellites, which require designers and engineers from various disciplines to cooperate with each other. MDO can be used to handle the conflicts that arise between these disciplines, and focuses on the optimal design of the system as a whole. However, it can also push designs to the brink of failure. In order to keep the system balanced, Reliability-based Design (RBD) must be incorporated into MDO. Consequently, new algorithms and methods have to be developed for RBMDO theory. This book provides an essential overview of MDO, RBD, and RBMDO and subsequently introduces key algorithms and methods by means of case analyses. In closing, it introduces readers to the design of DMSs and applies RBMDO methods to the design of the manned hull and the general concept design. The book is intended for all students and researchers who are interested in system design theory, and for engineers working on large, complex engineering systems.

Developed by French physicist Auguste Piccard and his son Jacques, the bathyscaph Trieste was a scientific marvel that allowed unprecedented scientific, technical, and military feats in the ocean depths. France and the United States both acquired and subsequently developed variants of the original bathyscaph. While both France and the United States employed the bathyscaph as a tool for scientific investigation of the deepest ocean depths, the U.S. Navy developed and employed the Trieste for military missions as well. From its earliest years, participants in the Trieste program realized that they were making history, blazing a trail into previously unexplored and unexploited depths, developing new capabilities and opening a new frontier. Comparisons with developments in space and the space-race between the United States and the Soviet Union often were made concerning the Trieste program and contemporary developments in undersea technologies and capabilities. The Trieste opened the entire oceans to exploration, exploitation, and operations. The bathyscaph was a first-generation system, a "Model-T" that spawned an entirely new industry and encouraged new concepts for deep-ocean naval operations. Advances in deep-sea technologies lacked the "gee-whiz" factor of the concurrent space race, but were highly significant in the development of new technology, new knowledge, and new military capabilities. Opening the Great Depths is the story of the three Trieste deep-ocean vehicles, their officers and enlisted men, and the civilians, often told in their own words, documenting for the first time the earliest years of humanity's probing into Earth's final frontier.
