This book was released on 1951 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: A longitudinal stability analysis of hydrofoil systems has been made. The equations of motion include the terms corresponding to an automatic control with finite time lag. The methods used for solution of such equations have been discussed for the case when the critical time lag of an automatic control - hydrofoil craft combination is desired. The resulting equations have been applied to the Cape Cod Boat, a 14 ft tandem foil test craft, which used an automatic control sensitive to displacements from a preset depth. The critical time lag was obtained for this craft based upon an assumed two degrees of freedom and flight at an intermediate depth of approximately two and one half chords below the surface. Both the frequency response method and the transcendental characteristic stability equation solution were employed to determine the aforementioned critical time lag. Further examination was made of the Cape Cod craft's stability characteristics when control gearings are varied and zero time lag in control is assumed. (Author).

Book excerpt: The hydrofoil boat in a seaway is a very complicated system. In its simplest form it may be treated as a rigid body. However, this representation is not always correct. In some cases it may be necessary to take into account other factors such as the gyroscopic effects of propellers, the dynamics of the control systems and the elastic behavior of the boat. In this report the general equations of motion of the hydrofoil boat, treated as a rigid body, are first derivedAND DISCUSSED. The gyroscopic effects of the propellers, the dynamics of the control systems and the effects of the elasticity of the boat are then considered and related to the equations of motion of the boat.

Download or read book LONGITUDINAL STABILITY EQUATIONS FOR HYDROFOIL CRAFT WITH CONSTANT LIFT CONTROL SYSTEM. written by and published by . This book was released on 1952 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: Longitudinal equations of motion are developed for a tandem foil hydrofoil craft with a constant lift control on the forward hydrofoil. The roots of the characteristic stability equation are interpreted in terms of the physical motions expected for the craft. Several of the component stability modes involved are independent of one another, thus permitting simplified solutions to the general case of 4 degrees of freedom without loss of accuracy. Control inertia and mass unbalance are shown to have a negligible effect upon the hydrofoil craft motions. The short period craft oscillation can be isolated in study by assuming constant forward velocity of the craft. Numerical correlation was based upon the Lantern configuration developed by the Hydrofoil Corp.

This book was released on 1963 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the large amount of computations involved in solving the equations of motion of a hydrofoil craft in a seaway, various simplified methods have been used in the past. Most of the methods fol lowing aircraft motions analyses were neglecting surge and added mass. It is shown that surge has a large effect on the heave and pitch motions while added mass and unsteady lift do not have significant effect. Furthermore, a boat with fully submerged foils can, in fact, be controlled through regular and irregular waves in both ahead and following seas. A computer program enabling very rapid evaluation of the motions through various seaconditions was prepared for IBM 7090 computer and the results were displayed on the television scope attached to the computer. Repro ductions of the results are presented. (Author).

Download or read book Marine Hydrodynamics, 40th anniversary edition written by J. N. Newman and published by MIT Press. This book was released on 2018-01-26 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: A textbook that offers a unified treatment of the applications of hydrodynamics to marine problems. The applications of hydrodynamics to naval architecture and marine engineering expanded dramatically in the 1960s and 1970s. This classic textbook, originally published in 1977, filled the need for a single volume on the applications of hydrodynamics to marine problems. The book is solidly based on fundamentals, but it also guides the student to an understanding of engineering applications through its consideration of realistic configurations. The book takes a balanced approach between theory and empirics, providing the necessary theoretical background for an intelligent evaluation and application of empirical procedures. It also serves as an introduction to more specialized research methods. It unifies the seemingly diverse problems of marine hydrodynamics by examining them not as separate problems but as related applications of the general field of hydrodynamics. The book evolved from a first-year graduate course in MIT's Department of Ocean Engineering. A knowledge of advanced calculus is assumed. Students will find a previous introductory course in fluid dynamics helpful, but the book presents the necessary fundamentals in a self-contained manner. The 40th anniversary of this pioneering book offers a foreword by John Grue.
