An investigation into how machines and living creatures fly, and of the similarities between butterflies and Boeings, paper airplanes and plovers. From the smallest gnat to the largest aircraft, all things that fly obey the same aerodynamic principles. In The Simple Science of Flight, Henk Tennekes investigates just how machines and creatures fly: what size wings they need, how much energy is required for their journeys, how they cross deserts and oceans, how they take off, climb, and soar. Fascinated by the similarities between nature and technology, Tennekes offers an introduction to flight that teaches by association. Swans and Boeings differ in numerous ways, but they follow the same aerodynamic principles. Biological evolution and its technical counterpart exhibit exciting parallels. What makes some airplanes successful and others misfits? Why does the Boeing 747 endure but the Concorde now seem a fluke? Tennekes explains the science of flight through comparisons, examples, equations, and anecdotes. The new edition of this popular book has been thoroughly revised and much expanded. Highlights of the new material include a description of the incredible performance of bar-tailed godwits (7,000 miles nonstop from Alaska to New Zealand), an analysis of the convergence of modern jetliners (from both Boeing and Airbus), a discussion of the metabolization of energy featuring Lance Armstrong, a novel treatment of the aerodynamics of drag and trailing vortices, and an emphasis throughout on evolution, in nature and in engineering. Tennekes draws on new evidence on bird migration, new wind-tunnel studies, and data on new airliners. And his analysis of the relative efficiency of planes, trains, and automobiles is newly relevant. (On a cost-per-seat scale, a 747 is more efficient than a passenger car.)

It introduces to the rotary-wing aerodynamics, with applications to helicopters, and application of the relevant principles to the aerodynamic design of a helicopter rotor and its blades. The basic aim of this book is to make a complete text covering both the basic and applied aspects of theory of rotary wing flying machine for students, engineers, and applied physicists. The philosophy followed in this book is that the subject of helicopter aerodynamics is covered combining the theoretical analysis, physical features and the application aspects. Considerable number of solved examples and exercise problems with answers are coined for this book. This book will cater to the requirement of numerical problems on helicopter flight performance, which is required for the students of aeronautical/aerospace engineering. SALIENT FEATURES: To provide an introductory treatment of the aerodynamic theory of rotary-wing aircraft To study the fundamentals of rotor aerodynamics for rotorcraft in hovering flight, axial flight, and forward flight modes To perform blade element analysis, investigate rotating blade motion, and quantify basic helicopter performance

What mysteries lurk in the depths of a glass of water? What makes the wispy clouds of vapour rising from your cup of hot coffee? Or the puffy white clouds hovering in the sky? Why do bubbles in your fizzy drinks get bigger the longer you wait? What keeps Jelly's water from oozing out? Why does your tongue stick to something frozen? Professor Pollack takes us on a fantastic voyage through water, showing us a hidden universe teeming with physical activity, providing cogent explanations to many of waters long-held secrets. In conversational prose, Pollack exposes where some scientists may have gone wrong, and instead lays a simple foundation for understanding how changes of water structure underlie most energetic transitions of form and motion on Earth. This seminal work, peppered with whimsical illustrations and simple diagrams invites us to open our eyes and re-experience our natural world, to take nothing for granted, and to reawaken our childhood dream of having things make sense.

Pilots must be provided explanations, predictions, factors of safety and control for high density altitude environments. Anytime a higher than standard temperature exists at a departure airport, improper planning and/or a lack of knowledge may lead to a fatal outcome. Attempting takeoff without a thorough knowledge and understanding of high density altitude takeoff parameters are known to be contributing factors in general aviation takeoff accidents. A critical ethnographic study was conducted to reveal cultural differences among the general aviation community, air carrier, and commuter and on demand operators. Takeoff distance, velocity, and time can be presented as a function of aircraft weight and provide a practical basis for other reliable information. Participants provide an unintended and unanticipated zero-rate condition encountered in an aviation operation. This study expands on participant's zero-rate concerns with ratio level measurements and graphs.

This is a book on how to design, build, and fly hydrofoil boats. It begins with the history and theory of hydrofoils, and continues with an explanation of flight characteristics, such as; stability, control, lift, drag, cavitation, and ventilation. Foil configurations, weight and balance, flying height, and roll management are covered as well as calculations of stress, hull configuration, and wing sizing. One section demonstrates methods for comparing designs, and explores specific design ideas for motorized, human powered, and sail powered hydrofoils. Piloting and trouble shooting are followed by a bibliography and index. This very complete book includes over 270 illustrations, charts and tables on the subject of creating hydrofoil boats. Because hydrofoils fly like airplanes, except in a denser fluid, the book's subject could be described as aerodynamics adapted to hydrofoils. It is the best book available for hydrofoil enthusiasts. There is no other book like it.

Geared toward advanced undergraduates and graduate students, this outstanding text surveys aeroelastic problems, their historical background, basic physical concepts, and the principles of analysis.

Despite the ongoing preventive actions, supervision failure remains the most serious contributor to aircraft accidents in the Brazilian Air Force (FAB). The Organizational Accidents Theory, introduced by James Reason (1997), focuses on the preexisting conditions that result from fallible decisions made by top management. Squadron Commanders are the managers who deal directly with frontline operations in the FAB, becoming the last managerial barriers to counteract flaw top-down decision-makings. The purpose of this study aims to assess squadron commanders' perceptions regarding the theory of Organizational Accidents to improve FAB's safety performance. Three research hypotheses have been formulated and answered. Surveys were sent to squadron commanders and 20 responded to them. Despite the basic understanding of aviation safety, the results show that squadron commanders need more education in advanced safety models as well as the theory of Organizational Accidents. Squadron Commanders also need a better decision-making process tailored for their managerial decisions.
