Book Synopsis Dynamics of Aircraft Flight by : Gilles Louis
Download or read book Dynamics of Aircraft Flight written by Gilles Louis and published by John Wiley & Sons. This book was released on 2022-07-20 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Performance calculations can be classified into three main types: lift, thrust and slope. Firstly, since the lift profile is known and unmodifiable from the time an aircraft is designed, the mass at a given speed or the speed at a given mass must be determined. Then, once the thrust of the engines and the mass are known, the slope must be calculated. Finally, once the slope is known (for example, level flight) as well as the mass, it is necessary to deduce the thrust; this is the position of the throttle control lever that ensures balance. The corresponding consumption must then be defined. Performance specifications for customer aircraft, such as manoeuvrability, fuel consumption, maintenance, safety and testability, have become ever more demanding with each generation of equipment. Major technical advances have been required: wing profiles, engines, materials to reduce mass, etc. This book presents a theoretical approach to flight mechanics that makes it possible to grasp the subject and links it with the empirical approach of manufacturers.
Book Synopsis Thermodynamics of Heat Engines by : Bernard Desmet
Download or read book Thermodynamics of Heat Engines written by Bernard Desmet and published by John Wiley & Sons. This book was released on 2022-12-28 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optimizing the process of converting heat into mechanical power is a major challenge when it comes to meeting targets for protecting primary energy resources and minimizing our environmental impact. For many years to come, the use of thermal engines will continue to be necessary for transportation on land, by sea and by air, as well as for many industrial applications. Against this background, Thermodynamics of Heat Engines aims to present a comprehensive overview of the thermodynamic concepts, including combustion, that are necessary for understanding the phenomena governing the energy efficiency of internal and external combustion engines as well as that of gas turbines and jet propulsion engines. Existing and developing industrial applications, based on combined heat and power (CHP) or the use of staged cycles, are presented, with particular attention paid to the recovery of lowtemperature waste heat. This book, which is mainly intended for university and engineering students but is also useful for engineers and technicians working in the fields concerned, provides a basis for reflection on the optimization of energy systems.
Book Synopsis Uniform Supersonic Flows In Chemical Physics: Chemistry Close To Absolute Zero Studied Using The Cresu Method by : Bertrand R Rowe
Download or read book Uniform Supersonic Flows In Chemical Physics: Chemistry Close To Absolute Zero Studied Using The Cresu Method written by Bertrand R Rowe and published by World Scientific. This book was released on 2022-05-18 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radioastronomy has painted an extraordinary picture of the Galactic interstellar medium, which displays an amazing organization and structuring of matter from very hot ultra-diluted media to very cold denser milieus considered as the cradles of stars. In these latter environments, the discovery of a chemical diversity of molecules, including those associated with precursors to life itself, immediately brought to light the question of the mechanisms leading to their formation and persistence at temperatures as low as 10 K. The chemical networks developed to understand telescope observations required a great deal of physical and chemical parameters relevant to interstellar conditions, particularly at very low temperatures. These included the rate coefficients of thousands of gas phase chemical reactions. Such data were missing in the 1970s, when the very first molecular discoveries were made. Then, in the early eighties, it was realized that uniform supersonic flows were ideal chemical reactors to study reaction kinetics at interstellar temperatures.Uniform Supersonic Flows in Chemical Physics reviews 40 years of use of such reactors, the so-called CRESU machines, focusing on major breakthroughs brought to chemical physics, physical chemistry, astrophysics and astrochemistry by the various experiments carried out with such apparatuses. The wealth of kinetic data at very low temperatures provided new targets for the predictions of theory, with new theoretical methods being developed to explain observed behavior. The first two chapters describe the physical context of reaction kinetics at very low temperatures and the requirements needed to run optimally such uniform supersonic flows, together with a historical perspective. Chapters 3 to 9 describe the various families of chemical processes that have been explored within the CRESU technique, highlighting major advances and offering an exhaustive up-to-date bibliography. Chapters 10 and 11 show how these experimental results have helped in improving the ideas in quantum chemistry and interstellar modeling. The book concludes with an overview of potential perspectives and new routes to be explored.
Book Synopsis Turbulence and Coherent Structures by : O. Métais
Download or read book Turbulence and Coherent Structures written by O. Métais and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 612 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last 25 years, one of the most striking advances in Fluid Mecha nics was certainly the discovery of coherent structures in turbulence: lab oratory experiments and numerical simulations have shown that most turbulent flows exhibit both spatially-organized large-scale structures and disorganized motions, generally at smaller scales. The develop ment of new measurement and visualization techniques have allowed a more precise characterization and investigation of these structures in the laboratory. Thanks to the unprecedented increase of computer power and to the development of efficient interactive three-dimensional colour graphics, computational fluid dynamicists can explore the still myste rious world of turbulence. However, many problems remain unsolved concerning the origin of these structures, their dynamics, and their in teraction with the disorganized motions. In this book will be found the latest results of experimentalists, theoreticians and numerical modellers interested in these topics. These coherent structures may appear on airplane wings or slender bodies, mixing layers, jets, wakes or boundary-layers. In free-shear flows and in boundary layers, the results presented here highlight the intense three-dimensional character of the vortices. The two-dimensional large scale eddies are very sensitive to three-dimensional perturbations, whose amplification leads to the formation of three-dimensional coherent vorti cal structures, such as streamwise, hairpin or horseshoe vortex filaments. This book focuses on modern aspects of turbulence study. Relations between turbulence theory and optimal control theory in mathematics are discussed. This may have important applications with regard to, e. g. , numerical weather forecasting.
Book Synopsis Advances in Aeronautical Sciences by : Th. Von Kármán
Download or read book Advances in Aeronautical Sciences written by Th. Von Kármán and published by Elsevier. This book was released on 2014-05-15 with total page 621 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in Aeronautical Sciences, Volume 3 contains the proceedings of the Second International Congress in the Aeronautical Sciences held in Zurich, Switzerland, on September 12-16, 1960. The papers explore advances in aeronautical sciences and cover topics ranging from the role of entropy in the aerospace sciences to the theory of hypersonic flow over blunt-nosed slender bodies. The effect of boundary layer transition at the leading edge of thin wings on general nose separation is also discussed, along with the aerodynamics of aircraft shapes for flight at supersonic speeds. This book is comprised of 28 chapters and begins with a review of the importance of entropy in the aerospace sciences, citing the work of Nicolaus Sadi Carnot and Rudolf Clausius as well as enthalpy and free enthalpy. The link between entropy and molecular theory is also described before turning to the physics of jet streams and the aerodynamics of jet flaps. Other chapters consider a wide range of problems both of theoretical and practical importance, including the flow around a circular cylinder; the theory of boundary layer; the physics of transition from laminar to turbulent flow; and the theory and experimental knowledge of transonic, supersonic, and hypersonic flows. Due attention is given to the re-entry of missiles and space vehicles into the atmosphere; problems of trajectories; guidance of space vehicles; and power generation in space. The economic and technical aspects of air transportation are also highlighted. This volume will be of interest to scientists and engineers in aeronautics and astronautics.

Download or read book Exercices et Problèmes d'Aérodynamique Fondamentale. 2e édition written by Airiau Christophe and published by Éditions Cépaduès. This book was released on 2023-07-27 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cet ouvrage d’exercices est l’ouvrage compagnon du livre de cours Aérodynamique Fondamentale. Issu d’un savoir et d’un savoir-faire très importants, il s’adresse aux étudiants de Master, aux élèves ingénieurs et même à des ingénieurs professionnels qui souhaitent apprendre à résoudre analytiquement ou numériquement des problèmes d’aérodynamique, souvent très concrets. Certains problèmes relativement complexes s’adressent à des doctorants de troisième cycle ou à des chercheurs qui auraient besoin dans leurs activités de recherche de données de référence en aérodynamique. À l’opposé certains exercices sont abordables dès le premier cycle universitaire et en classes préparatoires. Nous espérons aussi que cet ouvrage et les codes fournis pourront être utilisés par des enseignants pour préparer des travaux dirigés, des travaux pratiques, des projets ou des examens. Tout pilote ou passionné d’aéronautique pourra aussi y piocher des informations ou des données. Chaque chapitre est constitué de rappels, d’énoncés et de corrigés détaillés. De nombreux schémas, figures et tableaux permettent de mieux visualiser et de quantifier les données et les résultats associés aux différentes approches théoriques ou numériques. Au travers des quelque 120 exercices et problèmes présentés, cet ouvrage permet d’appliquer et de comprendre les différentes théories dans tous les régimes de vol : les basses vitesses en phase d’atterrissage ou décollage, les moyennes vitesses en vol de croisière subsonique ou supersonique et les très grandes vitesses hypersoniques lors de la rentrée atmosphérique d’engins spatiaux. Une suite logiciel (sous linux et Windows) assez unique, accessible librement sur GitHub, composée de codes dans les langages Python, Fortran, Matlab et Maple, permet de retrouver les solutions de 95 des sujets ou de réaliser ses propres développements ou projets en aérodynamique. Son utilisation exige cependant quelques connaissances en programmation et plus généralement en informatique.
