Far exceeding anything ever before written on the subject, The Development of the Rudder endeavors to unravel the mysteries of the evolution of a vital piece of seafaring equipment. And in the process, Lawrence V. Mott answers far-reaching questions on why some technologies develop and endure, while others are soon replaced. In this first considered historical overview of the rudder, Mott begins his examination in the Roman period, and from there traces rudder development through the middle centuries to the age of exploratory navigation, by which time the quarter-rudder had been replaced by the pintle-and-gudgeon rudder. Throughout, he offers a thorough analysis of the mechanics of these rudder systems, while never losing sight of the human interest that attends the radical changes brought on by innovation. The layperson will find in this unique work a penetrating look into the history of technology at sea - a history that defies the linear cosntructs often associated with developmental and evolutionary theory. Maritime historians, nautical archaeologists, and ship modelers will embrace this book as an invaluable reference, which includes useful appendixes filled with technical data for researchers and scholars.

When this assumption is made that the rolling motions alone or the lateral and rolling motions may be neglected in the calculations of rudder-free stability, it is possible to predict satisfactorily the characteristics of the long-period (Dutch roll type) rudder-free oscillation for airplanes only when the effective-dihedral angle is small. With these simplifying assumptions, however, satisfactory prediction of the short-period oscillation may be obtained for any dihedral. Further simplification of the theory based on the assumption that the rudder moment of inertia might be disregarded was found to be invalid because this assumption made it impossible to calculate the characteristics of the short-period oscillations.

Are you prepared? A training and reference manual for the great nationwide revival—which has already begun. The Wind and the Rudder: How to Live in the Power of the Spirit without Becoming Weird gives you everything you need to be part of God’s current move! Many times the wind of God’s Spirit moved powerfully through an individual, in a city, or across a nation, only to see healthy, long-lasting revival aborted due to the lack of a strong rudder. This book provides the stabilizing force during times of dramatic renewal and revival. The focus of The Wind and the Rudder is two-fold:1. To help an ocean of Jesus-followers discover the thrill, the adventure, and the passion of the Spirit-filled life they are called to live.2. To help believers who have experienced the Spirit discover balance, understanding, and a new sense of mission. A great nationwide revival is arriving—you can prepare yourself to absorb the many benefits of this amazing harvest opportunity!

Introduction: Directional control difficulties had been experienced in P-40 series airplanes in dive demonstrations and inadvertent entry into spins in service operations. At the request of the Army Air Forces, Materiel Command, quantitative measurements of rudder trim force change with speed and power, rudder force reversals in sideslips, and rudder positions in sideslips and straight flight of a P-40E airplane were made. Quantitative measurements of these items were also made on three other vertical tail arrangements supplied by the Curtiss-Wright Corporation. The results of these measurements are presented in this report.

The Boeing 737 has a history of rudder system-related anomalies, including numerous instances of jamming. A number of accidents and incidents were the result of the airplanes' unexpected movement of their rudders. During the course of the four and a half year investigation of the crash of USAir Flight 427 near Aliquippa, Pennsylvania, killing 132 people, the NTSB discovered that the PCU's dual servo valve could jam as well as deflect the rudder in the opposite direction of the pilots' input, due to thermal shock, caused when cold PCUs are injected with hot hydraulic fluid. This finally solved the mystery of sudden jamming of the rudders of this aircraft.

This book demonstrates that different rudder configurations have different hydrodynamic characteristics, which are influenced by the profile, the parameters, and the specific configuration. The author proposes new regression formulas to help naval architects quickly estimate the rudder-induced forces and moments in maneuvering. Furthermore, the author proposes and validates an integrated maneuvering model for both seagoing ships and inland vessels. Using the proposed regression formulas and maneuvering model, the specific impacts of rudder configurations on inland vessel maneuverability are studied. In turn, the book demonstrates the application of Reynolds-Averaged Navier–Stokes (RANS) simulations to obtain rudder hydrodynamic characteristics, and the integration of the RANS results into maneuvering models as an accurate estimation of rudder forces and moments needed to quantify the impacts of rudder configurations on ships’ maneuvering performance. In addition, the author proposes new criteria for the prediction and evaluation of inland vessel maneuverability. Simulations of ships with various rudder configurations are presented, in order to analyze the impacts of rudder configurations on ship maneuverability in different classic and proposed test maneuvers. Offering essential guidance on the effects of rudders for inland vessel maneuverability, and helping practical engineers make informed design choices, the book is of interest to researchers and academics in the field of naval engineering, as well as students of naval architecture. Industrial practitioners working on ship design may also find it beneficial.

An investigation was conducted to determine the floating characteristics of full-length plain and horn-balanced rudders during rotary tests at spinning attitudes of a typical low-wing personal-owner airplane model. The investigation also included the determination of the effects of the horizontal tail and wing on the rudder floating characteristics.
