Mechanical Engineering Reference Manual for the PE Exam, 12th Edition

Electric Motors and Control Techniques

Get greater flexibility, reliability, and reduced energy consumption from household appliances to automobiles. This book will show you how different types of motors operate and how electronic control devices can be used to improve efficiency in a wide range of applications. You'll get in-depth, updated coverage of: Electric motor control applications; dc and ac motors; Digital motors; Commutator-type motors; Noncommutator-types motors; Electric vehicles.

Electric Motors & Drives

Electric Motors and Drives is intended for non-specialist users of electric motors and drives, filling the gap between maths- and theory-based academic textbooks and the more prosaic 'handbooks', which provide useful detail but little opportunity for the development of real insight and understanding. The book explores all of the widely-used modern types of motor and drive, including conventional and brushless D.C., induction motors and servo drives, providing readers with the knowledge to select the right technology for a given job.

The third edition includes additional diagrams and worked examples throughout. New topics include digital interfacing and control of drives, direct torque control of induction motors and current-fed operation in DC drives. The material on brushless servomotors has also been expanded.

Austin Hughes' approach, using a minimum of maths, has established Electric Motors and Drives as a leading guide for electrical engineers and mechanical engineers, and the key to a complex subject for a wider readership, including technicians, managers and students.

* Acquire knowledge of and understanding of the capabilities and limitations of motors and drives without struggling through unnecessary maths and theory
* Updated material on the latest and most widely-used modern motors and drives, including brushless servomotors
* New edition includes additional diagrams and worked examples throughout

TERMINAL CHAOS: Why U.S. Air Travel Is Broken and How to Fix It (Library of Flight Series)

In total passenger miles, air travel has never been more popular. But as any frequent flyer knows, air travel problems are growing even faster long lines, lost luggage, overbooking, flight delays, and serious safety issues. And instead of doing something about it, the traveling public seems simply to be sitting down, buckling in, and allowing itself to be treated like sheep.

But it doesn't have to be this way. There are solutions to our air travel problems, real solutions that can make real differences. And they don t require 15 years to implement.

With decades of experience in civil aviation and policy, Drs. George Donohue and Russell Shaver are well qualified to assess the problems in the system and to offer responsible, workable solutions. Dr. Donohue, the current Director of the Center for Air Transportation Systems Research and a Professor of Systems Engineering at George Mason University (GMU), has extensive high-level experience at the Federal Aviation Administration and the Defense Advanced Research Projects Agency (DARPA). Dr. Shaver, formerly a senior RAND Corporation research analyst and now a visiting research fellow at GMU, served as chief scientist for policy analysis at the MITRE Center for Advanced Aviation System Development.

The stories they tell are compelling. They are high-profile horror stories passengers stranded for hours on the tarmac, flights canceled for bad weather when there s not a drop of rain anywhere near the flight path, and an overall sense of apathy and obstructionism among those responsible for managing the industry. Interestingly, these problems are not the inevitable result of the size or complexity of the U.S. system. Air transportation in Europe, with almost identical air traffic control systems and safety standards, is far better. Amsterdam moves 30% more passengers than Newark, but the average flight delay is an order of magnitude lower. In addition, a European Passenger s Bill of Rights giving distressed passengers the right to substantial and immediate compensation has been a powerful incentive for non-U.S. airlines to maintain their schedules.

The Causes

So just how did we get where we are in the U.S. system today? Donohue and Shaver cite multiple reasons for the chaos we now face. These causes include airline deregulation, multiple governmental agencies with no central oversight or responsibility, multiple corporate entities with conflicting agendas, and a technologically outdated air traffic control system. Even more importantly, there seems to be a complete absence of advocacy for the customer the passengers. The authors also explain that our air travel problems, if left unaddressed, are on a direct course to greatly impact the overall U.S. economy and harm our global competitiveness. In 2006 alone, the delays and cancellations cost U.S. travelers an estimated $3.2 billion. And in 2004 and 2005, the U.S. tourism industry is estimated to have lost $98 billion in revenue due to our air travel mess.

The Cures

Fortunately, Donohue and Shaver don t leave us in this state of chaos. Their provocative analysis not only identifies the causes and extent of the problems, but also provides us with a course heading that will put us on the path to recovery. The solutions they propose include holding the government decision-makers responsible, expanding the capacity of airports and airplanes, modernizing the air traffic control system, and implementing what the authors call the 30% solution to significantly reduce congestion.

In short, this book should be read by every airline passenger traveling in or through the United States. As a country,
