Book Synopsis Unsteady Transonic Flow by : Mårten T. Landahl
Download or read book Unsteady Transonic Flow written by Mårten T. Landahl and published by Courier Dover Publications. This book was released on 2019-04-17 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: This classic monograph on unsteady transonic flow — the flow of air encountered at speeds at or near the speed of sound — is of continuing interest to students and professionals in aerodynamics, fluid dynamics, and other areas of applied mathematics. After a brief Introduction, Swedish physicist Mårten T. Landahl presents a chapter in which the two-dimensional solution is derived, succeeded by a discussion of its relation to the subsonic and supersonic solutions. Three chapters on low aspect ratio configurations follow, covering triangular wings and similar planforms with curved leading edges, rectangular wings, and cropped delta wings, and low aspect ratio wing-body combinations. The treatment concludes with a consideration of the experimental determination of air forces on oscillating wings at transonic speeds.

Book Synopsis Calculation of Unsteady Transonic Aerodynamics for Oscillating Wings with Thickness by : S. Y. Ruo
Download or read book Calculation of Unsteady Transonic Aerodynamics for Oscillating Wings with Thickness written by S. Y. Ruo and published by . This book was released on 1975 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analytical approach is presented to account for some of the nonlinear characteristics of the transonic flow equation for finite thickness wings undergoing harmonic oscillation at sonic flight speed in an inviscid, shock-free fluid. The thickness effect is accounted for in the analysis through use of the steady local Mach number distribution over the wing at its mean position by employing the local linearization concept and a coordinate transformation. Computed results are compared with that of the linearized theory and experiments. Based on the local linearization concept, an alternate formulation avoiding the limitations of the coordinate transformation method is presented.
Book Synopsis Introduction to Transonic Aerodynamics by : Roelof Vos
Download or read book Introduction to Transonic Aerodynamics written by Roelof Vos and published by Springer. This book was released on 2015-03-04 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written to teach students the nature of transonic flow and its mathematical foundation, this book offers a much-needed introduction to transonic aerodynamics. The authors present a quantitative and qualitative assessment of subsonic, supersonic and transonic flow around bodies in two and three dimensions. The book reviews the governing equations and explores their applications and limitations as employed in modeling and computational fluid dynamics. Some concepts, such as shock and expansion theory, are examined from a numerical perspective. Others, including shock-boundary-layer interaction, are discussed from a qualitative point of view. The book includes 60 examples and more than 200 practice problems. The authors also offer analytical methods such as Method of Characteristics (MOC) that allow readers to practice with the subject matter. The result is a wealth of insight into transonic flow phenomena and their impact on aircraft design, including compressibility effects, shock and expansion waves, shock-boundary-layer interaction and aeroelasticity.

It now includes new numerical examples, a section on the ground effect, and state-space representation.
Book Synopsis Unsteady Transonic Aerodynamics of Pointed Bodies of Revolution in Supersonic Freestream by : P. Garcia Fogeda
Download or read book Unsteady Transonic Aerodynamics of Pointed Bodies of Revolution in Supersonic Freestream written by P. Garcia Fogeda and published by . This book was released on 1992 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method to determine the aerodynamic forces acting on oscillating pointed bodies of revolution in transonic-supersonic flight has been developed. The nonlinear equation for the mean-flow perturbation potential and the time linearized equation for the cross-flow perturbation potential are both of hyperbolic type, for the Mach number range of interest, and have been solved by the method of characteristics. The method is valid for arbitrary frequencies of oscillation and can be applied for rigid or flexible body motions. Results are presented for the stability force coefficients, unsteady pressure distributions and shock deformations for various body shapes and Mach numbers.

Book Synopsis Transonic Aerodynamics by : L. Pamela Cook
Download or read book Transonic Aerodynamics written by L. Pamela Cook and published by SIAM. This book was released on 1993-01-01 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume offers exciting results, perspectives, and case studies for the treatment of problems arising in transonic aerodynamics. New advances including triple deck theory, analysis of stagnation at the nose of a body, transonic choked flow, and the transonic area rule are presented. Interest in analyzing the transonic range of flight, its stability properties, and especially the question of designing reduced drag (shockless or weak shock) airfoils keeps growing. Present day commercial aircraft cruise in the transonic range. Mechanical and aeronautical engineers interested in compressible fluid flows, design of optimal wings, and an understanding of transonic flow held about wings and airfoils will find the book invaluable. This book is understandable to those with a knowledge of continuum mechanics (fluids) and asymptotic methods. It is appropriate for graduate courses in aerodynamics and mathematical methods.

This book was released on 2018-08-16 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development and application of transonic small disturbance codes for computing two dimensional flows, using the code ATRAN2, and for computing three dimensional flows, using the code ATRAN3S, are described. Calculated and experimental results are compared for unsteady flows about airfoils and wings, including several of the cases from the AGARD Standard Aeroelastic Configurations. In two dimensions, the results include AGARD priority cases for the NACA 64A006, NACA 64A010, NACA 0012, and MBB-A3 airfoils. In three dimensions, the results include flows about the F-5 wing, a typical wing, and the AGARD rectangular wings. Viscous corrections are included in some calculations, including those for the AGARD rectangular wing. For several cases, the aerodynamic and aeroelastic calculations are compared with experimental results. Goorjian, P. M. and Guruswamy, G. P.

Book Synopsis An Efficient Method for Computations of Three-Dimensional Unsteady Transonic Aerodynamics by : K. Y. Fung
Download or read book An Efficient Method for Computations of Three-Dimensional Unsteady Transonic Aerodynamics written by K. Y. Fung and published by . This book was released on 1985 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: For aeroelastic application, the present Transonic Equipment Strip (TES) method has established an efficient and cost effective procedure for unsteady flow computations of arbitrary wing planforms including control surface. According to the nature of three dimensional unsteady transonic flow, a method based on the TES model is developed which consists of two consecutive correction steps to a given unsteady two-dimensional code. The latter could be a time-linearized transonic code or a nonlinear one such as the LTRAN2 code. The correction steps are: first, the mean-flow correction step which involves an equivalent airfoil design procedure; and second, the spanwise phase correction step which accounts for the effects of acoustic wave propagation in three dimensions. Computed results using the TES method are compared with those obtained by current methods such as results using the TES method are compared with those obtained by current methods such as various versions of the XTRAN3S code, Isogai's full potential code, and measured data provided by the National Aerospace Laboratory and the Royal Aeronautical Establishment. Computed cases included rectangular wings in pitching and bending oscillations, the Northrop F-5 wing in pitching oscillation, the AGARD standard RAE wing with an oscillating flap, and the LANN wing in pitching oscillation. Assessments of the present approach and other existing methods are given. (KR).
Book Synopsis Unsteady Aerodynamics, Aeroacoustics, and Aeroelasticity of Turbomachines and Propellers by : H.M. Atassi
Download or read book Unsteady Aerodynamics, Aeroacoustics, and Aeroelasticity of Turbomachines and Propellers written by H.M. Atassi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 876 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first International Symposium on Unsteady Aerodynamics and Aero elasticity of Turbomachines was held in Paris in 1976, and was followed by symposia at Lausanne in 1980, Cambridge in 1984, Aachen in 1987, Bei jing in 1989, and Notre Dame in 1991. The proceedings published following these symposia have become recognized both as basic reference texts in the subject area and as useful guides to progress in the field. It is hoped that this volume, which represents the proceedings of the Sixth International Symposium on Unsteady Aerodynamics of Turbomachines, will continue that tradition. Interest in the unsteady aerodynamics, aeroacoustics, and aeroelasticity of turbomachines has been growing rapidly since the Paris symposium. This expanded interest is reflected by a significant increase in the numbers of contributed papers and symposium participants. The timeliness of the topics has always been an essential objective of these symposia. Another important objective is to promote an international exchange between scien tists and engineers from universities, government agencies, and industry on the fascinating phenomena of unsteady turbomachine flows and how they affect the aeroelastic stability of the blading system and cause the radiation of unwanted noise. This exchange acts as a catalyst for the development of new analytical and numerical models along with carefully designed ex periments to help understand the behavior of such systems and to develop predictive tools for engineering applications.
