Available in PDF, EPUB and Kindle. Book excerpt: The potential noise problems anticipated with future VTOL aircraft are analyzed and discussed in general terms, and a brief review of the basic principles of noise generation of various types of propulsion systems proposed for VTOL is included. Primary consideration is given to the noise environments produced in areas adjacent to VTOL sites, since they could cause the most serious noise problem limiting the usefulness of VTOL aircraft. Contours of perceived noise levels are compared for different takeoff and landing profiles of 3-4 passenger, 60 passenger, and 25 ton-lift-crane VTOL aircraft. Criteria and methods for assessing the response of communities to noise from V-port operations are discussed along with the problem of detection of military VTOL aircraft by means of noise. Recommendations are given on the requirements for future research on these noise problems with emphasis on the need for considering noise as an integral part of the design, selection, and test of VTOL aircraft.

Download or read book Aeromedical Aspects of Vibration and Noise written by J. C. Guignard and published by . This book was released on 1972 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vibration and noise are treated separately in Parts One and Two of this volume; while Part Three deals with the special aeromedical problem of auditory perception in aircrew and ground support personnel and its conservation. Part Four is a glossary of relevant terms. This division of the subject matter recognises that in practice vibration and noise are conveniently studied, measured and controlled as separate entities. It should, however, be borne in mind that these conditions rarely affect man singly. They are commonly present at the same time; and vibration and noise may often be associated with different kinds of environmental agent, such as heat, to make up a combined environmental stress. The human response to such combinations of stressful agents is still a largely neglected field of research.

Download or read book Aeronautical Research in Germany written by Ernst Heinrich Hirschel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
