Book Description
November, 2008 Anna Schwarz, Johannes Janicka In the last thirty years noise emission has developed into a topic of increasing importance to society and economy. In ?elds such as air, road and rail traf?c, the control of noise emissions and development of associated noise-reduction techno- gies is a central requirement for social acceptance and economical competitiveness. The noise emission of combustion systems is a major part of the task of noise - duction. The following aspects motivate research: • Modern combustion chambers in technical combustion systems with low pol- tion exhausts are 5 - 8 dB louder compared to their predecessors. In the ope- tional state the noise pressure levels achieved can even be 10-15 dB louder. • High capacity torches in the chemical industry are usually placed at ground level because of the reasons of noise emissions instead of being placed at a height suitable for safety and security. • For airplanes the combustion emissions become a more and more important topic. The combustion instability and noise issues are one major obstacle for the introduction of green technologies as lean fuel combustion and premixed burners in aero-engines. The direct and indirect contribution of combustion noise to the overall core noise is still under discussion. However, it is clear that the core noise besides the fan tone will become an important noise source in future aero-engine designs. To further reduce the jet noise, geared ultra high bypass ratio fans are driven by only a few highly loaded turbine stages.

Book Description
The Skycrane was the last creation of aircraft design pioneer Igor Sikorsky. In SKYCRANE: Igor Sikorsky's Last Vision, former Sikorsky Aircraft Executive Vice President John A. McKenna traces the development of this remarkable helicopter from original concept and early sketches to standout performer for the military and private industry. Responsible for building the first S-64 Skycrane in 1961 and for supporting its Army and commercial programs, McKenna has written a comprehensive history chronicling a radically designed helicopter that many thought would not succeed. Indeed, initial versions generated no orders. But General Harry Kinnards vision and advocacy resulted in the Skycranes support of combat operations in Vietnam as part of the groundbreaking concept of supporting Army troops with helicopters rather than trucks. In 1971 Erickson Lumber Company acquired the first Skycrane intended for commercial use to move timber deep in American forests. Owner Jack Erickson later acquired the world manufacturing and support rights to the aircraft creating Erickson Air-Crane Inc. A half century after its first flight the Skycrane continues to save lives, provide essential services, and earn daily profits worldwide. Beautifully illustrated with scores of historical photographs, SKYCRANE features interviews with engineers who designed and tested the helicopter and with Army pilots who flew it during combat in Vietnam. This engagingly written work is the definitive history of a unique and important aircraft.

Book Description
From the pioneering glider flights of Otto Lilienthal (1891) to the advanced avionics of today’s Airbus passenger jets, aeronautical research in Germany has been at the forefront of the birth and advancement of aeronautics. On the occasion of the centennial commemoration of the Wright Brother’s first powered flight (December 1903), this English-language edition of Aeronautical Research in Germany recounts and celebrates the considerable contributions made in Germany to the invention and ongoing development of aircraft. Featuring hundreds of historic photos and non-technical language, this comprehensive and scholarly account will interest historians, engineers, and, also, all serious airplane devotees. Through individual contributions by 35 aeronautical experts, it covers in fascinating detail the milestones of the first 100 years of aeronautical research in Germany, within the broader context of the scientific, political, and industrial milieus. This richly illustrated and authoritative volume constitutes a most timely and substantial overview of the crucial contributions to the foundation and advancement of aeronautics made by German scientists and engineers.

Book Description
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.

Book Description
"This report is intended to give public and port authorities, designers and contractors insight in the applications and the limitations of geosynthetics in waterfront structures. It is not a design book, but it should allow the users to quickly evaluate the possible use of a geotextile and to decide if a more detailed design is useful."--Introduction
