Download and read online Active Control of Aircraft Cabin Noise in PDF and EPUB Active Control of Aircraft Cabin Noise provides a bridge to fill the gap between robust control theory and practical applications of active noise control systems in aircraft cabin. Both the possibilities and limitations of structural solutions to enhance aircraft cabin comfort by reducing interior noise are discussed supported by a wide range of topics in engineering, from finite element modeling to multichannel adaptive feed-forward control, usually dealt separately in the literature. In addition, experimental noise attenuation results with passengers' subjective perceptions predicting the effects of cabin noise on comfort assessments is examined. Theoretical and experimental research is detailed enough to capture the interest of the non-expert in engineering who wishes to have an overview of some of the active noise control applications in aircraft. This book may be used as an advanced textbook by graduate and undergraduate students in aeronautical engineering, and would be an authoritative resource book for research into the subject. Contents:Aircraft Noise ControlFundamentals in Structural AcousticsTransmission of Sound through Multiple PartitionsAdaptive Control of Sound RadiationNoise-Reducing Smart WindowsActive Noise Control Experiments Readership: Researchers, advanced undergraduate and graduate students in aeronautical engineering.

Download and read online The Legal Status of Aircraft in PDF and EPUB I . Historical survey The legal status of aircraft is a problem that has given rise to innumerable questions ever since the earliest years of aviation. But the majority of these questions only relate to certain aspects of the legal status of aircraft, and the problem as a whole has hardly been studied at all. The evolutionary process in the study of a number of facets of the problem is outlined below. Nationality The question of the nationality of aircraft has always received a lot of attention. As far as the principle is concerned, there can be little dispute on this point nowadays. The subject of the nationality of aircraft was discussed at the aviation conferences which led to the Paris Convention in 1919, the Ibero-American Convention in 1926, the Havana Convention in 1928 and the Chicago Convention in 1944. According to Article 6 of the Paris Convention of 1919, an aircraft possesses the nationality of the State on whose register it is entered. The Ibero-American Convention of 1926 and the Pan-American Convention signed at Havana in 1928 start from the same principle.
Download and read online Analysis of Aircraft Structures in PDF and EPUB As with the first edition, this textbook provides a clear introduction to the fundamental theory of structural analysis as applied to vehicular structures such as aircraft, spacecraft, automobiles and ships. The emphasis is on the application of fundamental concepts of structural analysis that are employed in everyday engineering practice. All approximations are accompanied by a full explanation of their validity. In this new edition, more topics, figures, examples and exercises have been added. There is also a greater emphasis on the finite element method of analysis. Clarity remains the hallmark of this text and it employs three strategies to achieve clarity of presentation: essential introductory topics are covered, all approximations are fully explained and many important concepts are repeated.

Download and read online Aluminium Alloy Corrosion of Aircraft Structures in PDF and EPUB Bringing together the latest research, this book applies new modeling techniques to corrosion issues in aircraft structures. It describes complex numerical models and simulations from the microscale to the macroscale for corrosion of the aluminum (Al) alloys that are typically used for aircraft construction, such as AA2024. The approach is also applicable to a range of other types of structures, such as automobiles and other forms of ground vehicles. The main motivation for developing the corrosion models and simulations was to make significant technical advances in the fields of aircraft design (using current and new materials), surface protection systems (against corrosion and degradation) and maintenance. The corrosion models address pitting and intergranular corrosion (microscale) of Al alloys, crevice corrosion in occluded areas, such as joints (mesoscale), galvanic corrosion of aircraft structural elements (macroscale), as well as, the effect of surface protection methods (anodization, corrosion inhibitor release, clad layer, etc.). The book describes the electrochemical basis for the models, their numerical implementation, and experimental validation and how the corrosion rate of the Al alloys at the various scales is influenced by its material properties and the surface protection methods. It will be of interest to scientists and engineers interested in corrosion modeling, aircraft corrosion, corrosion of other types of vehicle structures such as automobiles and ground vehicles, electrochemistry of corrosion, galvanic corrosion, crevice corrosion, and intergranular corrosion.--
