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development through the middle centuries to the age of exploratory navigation, by which time the quarter-rudder had been replaced by the pintle-and-gudgeon rudder.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.

A New York Times Bestseller An audacious, irreverent investigation of human behavior—and a first look at a revolution in the making Our personal data has been used to spy on us, hire and fire us, and sell us stuff we don’t need. In Dataclysm, Christian Rudder uses it to show us who we truly are. For centuries, we’ve relied on polling or small-scale lab experiments to study human behavior. Today, a new approach is possible. As we live more of our lives online, researchers can finally observe us directly, in vast numbers, and without filters. Data scientists have become the new demographers. In this daring and original book, Rudder explains how Facebook "likes" can predict, with surprising accuracy, a person’s sexual orientation and even intelligence; how attractive women receive exponentially more interview requests; and why you must have haters to be hot. He charts the rise and fall of America’s most reviled word through Google Search and examines the new dynamics of collaborative rage on Twitter. He shows how people express themselves, both privately and publicly. What is the least Asian thing you can say? Do people bathe more in Vermont or New Jersey? What do black women think about Simon & Garfunkel? (Hint: they don’t think about Simon & Garfunkel.) Rudder also traces human migration over time, showing how groups of people move from certain small towns to the same big cities across the globe. And he grapples with the challenge of maintaining privacy in a world where these explorations are possible. Visually arresting and full of wit and insight, Dataclysm is a new way of seeing ourselves—a brilliant alchemy, in which math is made human and numbers become the narrative of our time.

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.

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.

WHAT'S IN STICK AND RUDDER: The invisible secret of all heavier-than-air flight: the Angle of Attack. What it is, and why it can't be seen. How lift is made, and what the pilot has to do with it. Why airplanes stall How do you know you're about to stall? The landing approach. How the pilot's eye functions in judging the approach. The visual clues by which an experienced pilot unconsciously judges: how you can quickly learn to use them. "The Spot that does not move." This is the first statement of this phenomenon. A foolproof method of making a landing approach across pole lines and trees. The elevator and the throttle. One controls the speed, the other controls climb and descent. Which is which? The paradox of the glide. By pointing the nose down less steeply, you descend more steeply. By pointing the nose down more steeply, you can glide further. What's the rudder for? The rudder does NOT turn the airplane the way a boat's rudder turns the boat. Then what does it do? How a turn is flown. The role of ailerons, rudder, and elevator in making a turn. The landing--how it's made. The visual clues that tell you where the ground is. The "tail-dragger" landing gear and what's tricky about it. This is probably the only analysis of tail-draggers now available to those who want to fly one. The tricycle landing gear and what's so good about it. A strong advocacy of the tricycle gear written at a time when almost all civil airplanes were taildraggers. Why the airplane doesn't feel the wind. Why the airplane usually flies a little sidewise. Plus: a chapter on Air Accidents by Leighton Collins, founder and editor of AIR FACTS. His analyses of aviation's safety problems have deeply influenced pilots and aeronautical engineers and have contributed to the benign characteristics of today's airplane. Stick and Rudder is the first exact analysis of the art of flying ever attempted. It has been continously in print for thirty-three years. It shows precisely what the pilot does when he flies, just how he does it, and why. Because the basics are largely unchanging, the book therefore is applicable to large airplanes and small, old airplanes and new, and is of interest not only to the learner but also to the accomplished pilot and to the instructor himself. When Stick and Rudder first came out, some of its contents were considered highly controversial. In recent years its formulations have become widely accepted. Pilots and flight instructors have found that the book works. Today several excellent manuals offer the pilot accurate and valuable technical information. But Stick and Rudder remains the leading think-book on the art of flying. One thorough reading of it is the equivalent of many hours of practice.

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.
