A rotorcraft is a class of aircraft that uses large-diameter rotating wings to accomplish efficient vertical take-off and landing. The class encompasses helicopters of numerous configurations (single main rotor and tail rotor, tandem rotors, coaxial rotors), tilting proprotor aircraft, compound helicopters, and many other innovative configuration concepts. Aeromechanics covers much of what the rotorcraft engineer needs: performance, loads, vibration, stability, flight dynamics, and noise. These topics include many of the key performance attributes and the often-encountered problems in rotorcraft designs. This comprehensive book presents, in depth, what engineers need to know about modelling rotorcraft aeromechanics. The focus is on analysis, and calculated results are presented to illustrate analysis characteristics and rotor behaviour. The first third of the book is an introduction to rotorcraft aerodynamics, blade motion, and performance. The remainder of the book covers advanced topics in rotary wing aerodynamics and dynamics.

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.

The Aircraft Designers: A Grumman Historical Perspective tells the behind-the-scenes story of the designers and engineers who conceived and built Grumman aircraft from the founding of the company in 1929 until its 1994 acquisition by Northrop. While Grumman aircraft have been previously documented, The Aircraft Designers focuses instead on the people, disciplines, processes, and anecdotes behind the creation of such past icons as the F6F Wildcat and TBF Avenger and modern-day weapon systems like the F-14 Tomcat, E-2 Hawkeye, EA-6B Prowler, and Joint STARS. Michael Ciminera has identified key team members who contributed to the creation and development of each new design, creating an unparalleled historical record of the aeronautical achievements of the Grumman Corporation. He has also chronicled the evolution from the aircraft design of the past, which bore the earmark of the chief engineer/designer, to today's complex aircraft systems, which require a significant team effort involving such disciplines as aerodynamics, structures, propulsion, avionics, systems analysis, software, simulation, testing, and much more. The Aircraft Designers provides a unique insight into the leadership traits, technical skills, and lasting contributions of Grumman's designers. It will stand as the definitive historical account of the people who made Grumman aircraft a reality.

"Sky Alert! What Happens When Satellites Fail" explores for the first time what our modern world would be like if we were suddenly to lose most, if not all, of our space assets. The author demonstrates humankind's dependence on space satellites and show what might happen to various aspects of our economy, defense, and daily lives if they were suddenly destroyed. The book opens with a consideration of how our space assets might be lost in the first place: through orbital debris, war, and solar storms. The author then looks at what would happen if our satellites were lost, including the effect on weather forecasting, and the Global Positioning System, explaining GPS in detail and its importance to the military, including spy satellites and military reconnaissance, commerce, civilians, communications and remote sensing - both resource monitoring and locating and environmental monitoring and science. The effects of losing such assets as the International Space Station as well as such research satellites as the Hubble Space Telescope or the Chandra X-Ray Observatory are also considered. Part III of the book looks at how we can protect our satellites, preparing for the worst, reducing the growth and amount of orbital debris, preventing acts of war in space and hardening against space radiation. The book ends on an optimistic note: most spacefaring nations are now working together to develop new technologies to reduce the threat posed by orbital debris and in-space nuclear detonations and treaties exist to limit the development and use of weapons in space. Finally, it is hoped that it will not be long before we will be able to better predict and take precautions against solar storms. The global economy has now become so dependent upon satellites that their loss would be devastating - to the economy, to national security, and potentially, to the day-to-day survival of those who live in the world's most advanced economies.

This is an ideal book for graduate students and researchers interested in the aerodynamics, structural dynamics and flight dynamics of small birds, bats and insects, as well as of micro air vehicles (MAVs), which present some of the richest problems intersecting science and engineering. The agility and spectacular flight performance of natural flyers, thanks to their flexible, deformable wing structures, as well as to outstanding wing, tail and body coordination, is particularly significant. To design and build MAVs with performance comparable to natural flyers, it is essential that natural flyers' combined flexible structural dynamics and aerodynamics are adequately understood. The primary focus of this book is to address the recent developments in flapping wing aerodynamics. This book extends the work presented in Aerodynamics of Low Reynolds Number Flyers (Shyy et al. 2008).
