This book was released on 2020-08-28 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Currently the only human powered swimming device widely sold on the market are swim flippers. However, flippers are not efficient for the human body, and there is a potential to increase the speed while swimming with a device. This thesis is the planning, design, construction, and prototyping of a new human powered swimming device which increases human efficiency and speed in water. This device uses a squatting motion to drive counter rotating propellers up and down a threaded shaft creating the propulsion force to move the swimmer forward. The design of this device is primarily geared towards scuba divers and swimmers moving beneath the water surface. Through various tests we were able to prove that the design concept is valid, but alterations are still necessary to reach optimal speed. One such improvement would be enlarging the size of the propeller to increase the force generated with each leg thrust.

This book was released on 1991 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: The oceanographic community is moving towards unmanned autonomous vehicles to gather data and monitor scientific sites. The mission duration of these vehicles is dependent primarily on the power consumption of the propulsion system, the control system and the sensor packages. A customized propulsion thruster is designed. This includes a specialized propeller tailored to ABE and a matched motor and transmission. A non-linear lumped parameter model of the thruster is developed and experimentally verified. The model is used to predict thruster performance and compare the design thruster with other variants of propeller and motor/transmission combinations. The results showed that there is a trade-off between rapid dynamic response and power conservation. For the typical ABE trajectory, the designed thruster provides good dynamic response and the lowest power consumption of all the modelled thruster units.

Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive method which designs the propeller blades with the maximum efficiency to move a given underwater vehicle at a specified speed is introduced. A previously developed nonlinear optimization algorithm which defines the blade shape by 4×4 B-spline polygon is applied for a target propeller thrust and a given inflow. The propeller performance is evaluated by a vortex-lattice method (VLM) within the optimization scheme. The interaction of the propeller with hull (and duct) is accounted for by coupling the VLM with a Reynolds-Averaged Navier-Stokes (RANS) solver, in order to determine the hull resistance, the propeller thrust, and the propeller inflow. The optimization method as well as the propeller/hull interaction method continue until the propeller thrust and the hull resistance equal each other. The method is applied to design various open, ducted, and contra-rotating propellers for a given underwater vehicle. Several combinations of propeller size and propeller RPM are studied. Additional pressure constraints, such as the minimum pressure constraint and the pressure difference constraint, are imposed for some cases. The effect of propeller diameter and propeller rotational speed on the resulting propeller performance and on the required power are explored, providing proof of concept for the presented method as well as guidance to the propeller designer

This book was released on 2018-06-15 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Human Powered Submarine Team has been in existence at Virginia Tech since its conception in 1993. Since then, it has served as a way for engineering students from many different disciplines to implement design conception and realization. The first submarine built was Phantom 1, a two-man submarine made of fiberglass. After construction was complete, Phantom 1 was ready for racing, but, unfortunately, suffered fatal problems come race time. The submarine team slowed down a bit after experiencing racing problems, but was revived in 1995 when design efforts for a new two-man submarine, the Phantom 2 commence. The propulsion system consisted of a chain and gear drive system using an ultra-light helicopter tail rotor for a propeller. Although the team learned valuable lessons as a result of Phantom 1's problems, Phantom 2 still experiences problems at races. After various parts of Phantom 2 are redesigned, it is once again ready for racing and proves that the redesign was well worth the time and effort. In 1997, Phantom 2 not only finishes its first race, held in San Diego, California, but comes in third. This success sparks yet another revival of the submarine team and design for the team's current project, the Phantom 3, a one-man submarine, is started. In 1998, the plug for Phantom 3 is built and the hull is constructed. With so many past problems from which to learn, Phantom 3 promises to be the fastest and best-designed submarine the team has developed thus far. The current speed world-record is 7 knots.
