Download or read book Some Effects of Flight Path and Atmospheric Variations on the Boom Propagated from a Supersonic Aircraft written by Raymond L. Barger and published by . This book was released on 1964 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Equations for the shock wave envelope and cusp line associated with the boom propagated from a supersonic aircraft are formulated in terms of the moving-trihedral coordinate system for flight in a uniform atmosphere and also in an atmosphere with a linear sound-speed gradient. Ray-tube theory is used to calculate the lateral distribution of boom intensity in an atmosphere with a linear sound-speed gradient and also to investigate the effect of a general wind and sound-speed gradient on the ground-track intensity. The relative effects of wind and temperature gradient are treated. The mechanism of focusing by winds and by ground structures are discussed qualitatively.

Download or read book A Nonlinear Theory for Predicting the Effects of Unsteady Laminar Turbulent Or Transitional Boundary Layers on the Attenuation of Shock Waves in a Shock Tube with Experimental Comparison written by Robert L. Trimpi and published by . This book was released on 1958 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: The linearized attenuation theory of NACA Technical Note 3375 is modified in the following manner: (a) an unsteady compressible local skin-friction coefficient is employed rather than the equivalent steady-flow incompressible coefficient; (b) a nonlinear approach is used to permit application of the theory to large attenuations; and (c) transition effects are considered. Curves are presented for predicting attenuation for shock pressure ratios up to 20 and a range of shock-tube Reynolds numbers. Comparison of theory and experimental data for shock wave strengths between 1.5 and 10 over a wide range of Reynolds numbers shows good agreement with the nonlinear theory evaluated for a transition Reynolds nuniber of 2.5 million.

Download or read book Effects of Noise On Wildlife written by John Fletcher and published by Elsevier. This book was released on 2012-12-02 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effects of Noise on Wildlife emerged from the Symposium on the Effects of Noise on Wildlife, organized by ICA-WG4 as part of the 9th International Congress on Acoustics in Madrid, Spain, July 4-9, 1977. The book begins by examining some popular and relatively well-known aspects of animal behavior in relation to noise. This is followed by separate chapters on the physiological responses of large domestic animals to various sound environments; the effects of sonic booms on native fauna; wildlife-powerline interactions; the effects of transmission line audible noise on wildlife; and the effects of acoustical noise on selected marine biological systems. Subsequent chapters deal with the effects of noise stress on gestating female mice and the environmental impact of noisy activities on wildlife. The book concludes with a discussion of the impact of existing noise-related policy on animals and government and public policy needs. This book is intended for readers in administrative services and agencies responsible for nature protection.
