Available in PDF, EPUB and Kindle. Book excerpt: Whirl Flutter of Turboprop Aircraft Structures, Second Edition explores the whirl flutter phenomenon, including theoretical, practical, analytical and experimental aspects of the matter. Sections provide a general overview regarding aeroelasticity, discussions on the physical principle and the occurrence of whirl flutter in aerospace practice, and experimental research conducted, especially from the 60s. Other chapters delve into analytical methods such as basic and advanced linear models, non-linear and CFD based methods, certification issues including regulation requirements, a description of possible certification approaches, and several examples of aircraft certification from aerospace. Finally, a database of relevant books, reports and papers is provided. This updated and expanded second edition covers new chapters including both analytical and experimental aspects of the subject matter. - Provides complex information on turboprop aircraft whirl flutter phenomenon - Presents both theoretical and practical (certification related) issues - Includes experimental research as well as analytical models (basic and advanced) of matter - Includes both early-performed works and recent developments - Contains a listing of relevant books and reports

Download or read book Prop3d written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-10 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: This guide describes the input data required, for steady or unsteady aerodynamic and aeroelastic analysis of propellers and the output files generated, in using PROP3D. The aerodynamic forces are obtained by solving three dimensional unsteady, compressible Euler equations. A normal mode structural analysis is used to obtain the aeroelastic equations, which are solved using either time domain or frequency domain solution method. Sample input and output files are included in this guide for steady aerodynamic analysis of single and counter-rotation propellers, and aeroelastic analysis of single-rotation propeller.

Download or read book Aerosol Sampling written by James H. Vincent and published by John Wiley & Sons. This book was released on 2007-04-04 with total page 636 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive account of the important field of aerosol sampling as it is applied to the measurement of aerosols that are ubiquitous in occupational and living environments, both indoor and outdoor. It is written in four parts: Part A contains 9 chapters that describe the current knowledge of the physical science that underpins the process of aerosol sampling. Part B contains 4 chapters, which present the basis of standards for aerosols, including the link with human exposure by inhalation. Part C contains 7 chapters that cover the development of practical aerosol sampling instrumentation, and how technical designs and methods have evolved over the years in order that aerosol sampling may be carried out in a manner matching the health-related and other criteria that have been proposed as parts of standards. Finally Part D contains 6 chapters that describe how a wide range of aerosol sampling instruments have performed when they have been applied in the field in both occupational and ambient atmospheric environments, including how different instruments, nominally intended to measure the same aerosol fraction, compare when used side-by-side in the real world. The book draws together all that is known about aerosol sampling, for the benefit of researchers and practitioners in occupational and environmental health and all other fields of science and engineering where aerosols are of interest.
Download or read book A Dictionary of Mnemonics PLE Memory written by Various and published by Psychology Press. This book was released on 2014-05-09 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Greeks invented them. All manner of people in the European Middle Ages used them, often with creative and brilliant effect. Victorian schoolmasters in England almost buried them and the pupils who had to cram facts parrot-fashion. Originally published in 1972, this title brought mnemonics back into focus with a new collection designed for current use. A mnemonic is anything that gets your memory working. When in the month does the third quarter-day fall? What order have the planets from the sun? Are you sure about the kings and queens of England? People nowadays have so much to remember that even those quite happy with √2 = 1.414 may prefer to chant ‘I wish I know the root of two’ and remind themselves in that way. Although some entries are very much of their time, this title reminds us that mnemonics are still a useful tool in a world where technology means most people feel they have little need to remember.
