Patterned after volumes in McGraw-Hill's "Time-Saver Standards" series in the architecture program (and Wiley's "Architectural Graphic Standards") and vastly expanding the range of the best-selling "Mechanisms and Mechanical Devices Sourcebook" by Chironis, this major new handbook presents a full array of key machine elements used in a wide range of applications. Filled with thousands of illustrations, it provides a quick-look-up resource of pictorial detail (worth many pages of text) for the busy engineer looking for the right device for the right application all systematically organized for easy access.

The development of clean, sustainable energy systems is one of the pre-eminent issues of our time. Most projections indicate that combustion-based energy conversion systems will continue to be the predominant approach for the majority of our energy usage, and gas turbines will continue to be important combustion-based energy conversion devices for many decades to come, used for aircraft propulsion, ground-based power generation, and mechanical-drive applications. This book compiles the key scientific and technological knowledge associated with gas turbine emissions into a single authoritative source. The book has three sections: the first section reviews major issues with gas turbine combustion, including design approaches and constraints, within the context of emissions. The second section addresses fundamental issues associated with pollutant formation, modeling, and prediction. The third section features case studies from manufacturers and technology developers, emphasizing the system-level and practical issues that must be addressed in developing different types of gas turbines that emit pollutants at acceptable levels.

Aviation fuel hydrant systems at airports are the penultimate step in the delivery chain of aviation fuel into aircraft. It is therefore imperative to ensure that the quality and cleanliness of the jet fuel in the hydrant is maintained at all times. This publication has been developed to assist in the optimisation of hydrant system operations. It provides recommended practices for operational checks, inspections and maintenance procedures to ensure aviation fuel quality assurance and cleanliness standards are met. It also provides recommendations for associated equipment, from pump sets to hydrant pit valves and for those undertaking routine checks and inspections of such equipment. This publication is applicable to owners, operators and users of aviation fuel hydrant systems at airports worldwide. It will also be of interest to procurement managers of equipment and materials for hydrant system inspection, maintenance and checking purposes, including service providers. Hydrant system designers will also find this publication useful as background information on the expectations of hydrant system owners and operators. This publication includes a free A3 annual planner pull-out/separate downloadable pdf.

"Aviation Logistics" demonstrates and explains how the rapidly evolving global logistics industry works in close partnership with the aviation operators to achieve fast and efficient facilitation. It examines the different sectors of products used by air freight and how carriers are responding to market demands with new and better methods and technologies.Technology and its resulting efficiency and transparency are a central part: for example, the adoption of electronic processing systems, screening of cargo, new warehousing technologies and the ability to track shipments through the system, are facilitating faster deliveries and reducing loss. Global markets and economies are constantly evolving and the supply chain business with its transport partners must be proactive for the future."Aviation Logistics" also reviews the changes in manufacturing and production methods -- these will be illustrated by case studies which will illustrate how different challenges are met in varied markets.

The book opens with a discussion of the vorticity-dynamic formulation of the low Mach number viscous flow problem. Physical aspects of the velocity and the vorticity fields, their instantaneous relationship, and the transport of vorticity in viscous fluids are examined for steady and unsteady flows. Subsequently, the mathematical aspects of vorticity dynamics and issues of initial and boundary conditions for the viscous flow problem are treated rigorously using classical analyses. Coverage includes evolution of the vorticity field which surrounds and trails behind airfoils and wings, generalizations of Helmholtz' vortex theorems and the Biot-Savart Law. A theorem is introduced that relates the aerodynamic force to the vorticity moment and the applications of the theorem are reviewed. Interpretations of the Kutta-Joukowski theorem and Prandtl's lifting line theory for vorticity dynamics are presented and wake integral methods are reviewed. The virtual-mass effect is shown to be the seminal event in unsteady aerodynamics and a simple approach for evaluating virtual-mass forces on the basis of vorticity dynamics is presented. The book presents a modern viewpoint on vorticity dynamics as the framework for understanding and establishing the fundamental principles of viscous and unsteady aerodynamics. It is intended for graduate-level students of classical aerodynamics and researchers exploring the frontiers of fully unsteady and non-streamlined aerodynamics.

Fundamentals of Spacecraft Attitude Determination and Control provides the fundamental concepts and mathematical basis for spacecraft attitude determination and control. It is intended to serve as both a textbook for undergraduate and graduate students and as a reference guide for practicing professionals. A primary motivation of this text is to develop the theory of attitude determination from first principles to practical algorithms, because very few of the existing texts on spacecraft control treat spacecraft attitude determination in depth. We emphasize specific applications so the reader can understand how the derived theory is applied to actual orbiting spacecraft. We also highlight some simplified analytical expressions that can serve as first cut analyses for more detailed studies and are especially important in the initial design phase of a spacecraft attitude determination and control system.
