This book was released on 2018-06-19 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aircraft engine noise research in the United States has made considerable progress over the past 10 years for both subsonic and supersonic flight applications. The Advanced Subsonic Technology (AST) Noise Reduction Program started in 1994 and will be completed in 2001 without major changes to program plans and funding levels. As a result, significant progress has been made toward the goal of reducing engine source noise by 6 EPNdB (Effective Perceived Noise level in decibels). This paper will summarize some of the significant accomplishments from the subsonic engine noise research performed over the past 10 years. The review is by no means comprehensive and only represents a sample of major accomplishments.

Download or read book Aviation Noise Impact Management written by Laurent Leylekian and published by Springer. This book was released on 2022-03-15 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book provides a view into the state-of-the-art research on aviation noise and related annoyance. The book will primarily focus on the achievements of the ANIMA project (Aviation Noise Impact Management through Novel Approaches), but not exclusively. The content has a broader theme in order to encompass. regulation issues, the ICAO (International Civil Aviation Organization) balanced approach, progresses made on technologies and reduction of noise at source, impact of possible future civil supersonic aircraft, land-use planning issues, as well as the core topics of the ANIMA project, i.e. impact on human beings, annoyance, quality of life, health and findings of the project in this respect. This book differs from traditional research programmes on aviation noise as the authors endeavour, not to lower noise at source, but to reduce the annoyance. This book examines these non-acoustic factors in an effort to help those most affected by aviation noise – communities living close to airports, and also help airport managers, policy-makers, local authorities and researchers to deal with this issue holistically. The book concludes with some recommendations for EU, national and local policy-makers, airport and aviation authorities, and more broadly a scientifically literate audience. These recommendations may help to identify gaps for progress in terms of research but also genuine implementation actions for political and regulatory authorities.

Download or read book Recent Developments in High Speed Transport written by Dmitry Yu. Strelets and published by Springer Nature. This book was released on 2023-04-10 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the basic concepts and various aspects of creating a new generation supersonic passenger aircraft. It presents the fundamental and applied problems essential to the design of aircraft of this type. Solutions to the problems of reducing supersonic boom, environmental noise, harmful emissions, increasing the efficiency of propulsion systems, and the general concept and certification are described. The development of high-speed transport, as a means of improving mobility and quality of life, is a relevant task for research teams in many countries. The publication includes selected articles from the 1st International Conference on High-Speed Transport Development, organized by the Moscow Aviation Institute (National Research University) which, by participating in many research and commercial projects (including international ones) has accumulated a lot of competencies sufficient to act as a platform for knowledge exchange in this field. The target audience of this book are researchers working on high-speed transport, postgraduate students, as well as any individuals willing to broaden their knowledge of high-speed aircraft.
