Book Description
Technologies for developing radically new aerovehicles that would combine quantum leaps in cost, safety, and performance benefits with environmental friendliness have appeared on the horizon. This report provides both an assessment of the current state-of-the-art in flow and noise control and a vision for the potential gains to be made, in terms of performance benefit for civil and military aircraft and a unique potential for noise reduction, via future advances in flow and noise technologies. This report outlines specific areas of research that will enable the breakthroughs necessary to bring this vision to reality. Recent developments in many topics within flow and noise control are reviewed. The flow control overview provides succinct summaries of various approaches for drag reduction and improved maneuvering. Both exterior and interior noise problems are examined, including dominant noise sources, physics of noise generation and propagation, and both established and proposed concepts for noise reduction. Synergy between flow and noise control is a focus and, more broadly, the need to pursue research in a more concurrent approach involving multiple disciplines. Also discussed are emerging technologies such as nanotechnology that may have a significant impact on the progress of flow and noise control.Thomas, Russell H. and Choudhari, Meelan M. and Joslin, Ronald D.Langley Research CenterNOISE REDUCTION; AEROSPACE ENGINEERING; AEROSPACE VEHICLES; FLOW DISTRIBUTION; CONTROL SYSTEMS DESIGN; TECHNOLOGY ASSESSMENT; DRAG REDUCTION; COMPUTERIZED SIMULATION

Book Description
The study of hydrodynamic stability is fundamental to many subjects, ranging from geophysics and meteorology through to engineering design. This treatise covers both classical and modern aspects of the subject, systematically developing it from the simplest physical problems, then progressing chapter by chapter to the most complex, considering linear and nonlinear situations, and analysing temporal and spatial stability. The authors examine each problem both analytically and numerically: many chapters end with an appendix outlining relevant numerical techniques. All relevant fluid flows are treated, including those where the fluid may be compressible, or those from geophysics, or those that require salient geometries for description. Details of initial-value problems are explored equally with those of stability. As a result, the early transient period as well as the asymptotic fate for perturbations for a flow can be assessed. The text is enriched with many exercises, copious illustrations and an extensive bibliography and the result is a book that can be used with courses on hydrodynamic stability or as an authoritative reference for researchers.

In this second edition the opportunity has been taken to update the text and, most importantly, provide solutions to the numerous extended exercises.

Book Description
Australian High Country Raptors covers raptor species that regularly breed in the high country above 600 metres, from Goulburn in New South Wales down to the hills outside Melbourne, Victoria. Author Jerry Olsen explores the nature of these striking animals that are classified as Accipitriformes (diurnal hawks, falcons, kites and eagles), Falconiformes and Strigiformes (nocturnal owls). Comparisons between these high country raptors and lower-elevation breeders are also provided, in addition to comparisons with raptors found overseas, especially from North America and Europe. The book begins with a description of habitats and vegetation types in the high country, and which raptors are likely to be seen in each habitat type. It continues with sections on finding and watching raptors, raptor identification, hunting styles, food, breeding and behaviour, and conservation. Appendices provide species accounts for diurnal breeding species in the high country, with basic information about their ecology, distribution and conservation, as well as detailed instructions about handling an injured or orphaned raptor. Illustrated throughout with photographs and drawings, Australian High Country Raptors offers readers a chance to look into the lives of Australia’s fascinating birds of prey.
