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.

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.

Geared toward advanced undergraduates and graduate students, this outstanding text surveys aeroelastic problems, their historical background, basic physical concepts, and the principles of analysis. It has also proven highly useful to designers and engineers concerned with flutter, structural dynamics, flight loads, and related subjects.

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.

In the rapidly advancing field of flight aerodynamics, it is important for students to completely master the fundamentals. This text, written by renowned experts, clearly presents the basic concepts of underlying aerodynamic prediction methodology. These concepts are closely linked to physical principles so that they may be more readily retained and their limits of applicability are fully appreciated. The ultimate goal is to provide the student with the necessary tools to confidently approach and solve of practical flight vehicle design problems of current and future interest. The text is designed for use in course in aerodynamics at the advanced undergraduate or graduate level. A comprehensive set of exercise problems is included at the end of each chapter.

This essential book describes the mathematical formulations and subsequent computer simulations required to accurately project the trajectory of spacecraft and rockets in space, using the formalism of optimal control for minimum-time transfer in general elliptic orbit. The material will aid research students in aerospace engineering, as well as practitioners in the field of spaceflight dynamics, in developing simulation software to carry out trade studies useful in vehicle and mission design. It will teach readers to develop flight software for operational applications in autonomous mode, so to actually transfer space vehicles from one orbit to another. The practical, real-life applications discussed will give readers a clear understanding of the mathematics of orbit transfer, allow them to develop their own operational software to fly missions, and to use the contents as a research tool to carry out even more complex analyses.

Why do aircraft fly? How do their wings support them? In the early years of aviation, there was an intense dispute between British and German experts over the question of why and how an aircraft wing provides lift. The British, under the leadership of the great Cambridge mathematical physicist Lord Rayleigh, produced highly elaborate investigations of the nature of discontinuous flow, while the Germans, following Ludwig Prandtl in Gottingen, relied on the tradition called "technical mechanics" to explain the flow of air around a wing. Much of the basis of modern aerodynamics emerged from this remarkable episode, yet it has never been subject to a detailed historical and sociological analysis. In "The Enigma of the Aerofoil", David Bloor probes a neglected aspect of this important period in the history of aviation. Bloor draws upon papers by the participants - their restricted technical reports, meeting minutes, and personal correspondence, much of which has never before been published - and reveals the impact that the divergent mathematical traditions of Cambridge and Gottingen had on this great debate. Bloor also addresses why the British, even after discovering the failings of their own theory, remained resistant to the German circulation theory for more than a decade. The result is essential reading for anyone studying the history, philosophy, or sociology of science or technology - and for all those intrigued by flight.

Space Micropropulsion for Nanosatellites: Progress, Challenges and Future features the latest developments and progress, the challenges faced by different researchers, and insights on future micropropulsion systems. Nanosatellites, in particular cubesats, are an effective test bed for new technologies in outer space. However, most of the nanosatellites have no propulsion system, which subsequently limits their maneuverability in space.

Spacecraft Attitude Control: A Linear Matrix Inequality Approach solves problems for spacecraft attitude control systems using convex optimization and, specifi cally, through a linear matrix inequality (LMI) approach. High-precision pointing and improved robustness in the face of external disturbances and other uncertainties are requirements for the current generation of spacecraft. This book presents an LMI approach to spacecraft attitude control and shows that all uncertainties in the maneuvering process can be solved numerically. It explains how a model-like state space can be developed through a mathematical presentation of attitude control systems, allowing the controller in question to be applied universally. The authors describe a wide variety of novel and robust controllers, applicable both to spacecraft attitude control and easily extendable to second-order systems. Spacecraft Attitude Control provides its readers with an accessible introduction to spacecraft attitude control and robust systems, giving an extensive survey of current research and helping researchers improve robust control performance.

Dynamics and Simulation of Flexible Rockets provides a full state, multiaxis treatment of launch vehicle flight mechanics and provides the state equations in a format that can be readily coded into a simulation environment. Various forms of the mass matrix for the vehicle dynamics are presented. The book also discusses important forms of coupling, such as between the nozzle motions and the flexible body. This book is designed to help practicing aerospace engineers create simulations that can accurately verify that a space launch vehicle will successfully perform its mission. Much of the open literature on rocket dynamics is based on analysis techniques developed during the Apollo program of the 1960s. Since that time, large-scale computational analysis techniques and improved methods for generating Finite Element Models (FEMs) have been developed. The art of the problem is to combine the FEM with dynamic models of separate elements such as sloshing fuel and moveable engine nozzles. The pitfalls that may occur when making this marriage are examined in detail.

This book provides a thorough description of actual, working aerodynamic design and analysis systems, for both axial-flow and radial-flow turbines. It describes the basic fluid dynamic and thermodynamic principles, empirical models and numerical methods used for the full range of procedures and analytical tools that an engineer needs for virtually any type of aerodynamic design or analysis activity for both types of turbine. The book includes sufficient detail for readers to implement all or part of the systems. The author provides practical and effective design strategies for applying both turbine types, which are illustrated by design examples. Comparisons with experimental results are included to demonstrate the prediction accuracy to be expected. This book is intended for practicing engineers concerned with the design and development of turbines and related machinery.
