Progress in Aeronautical Sciences

Progress in Aeronautical Sciences, Volume 5, contains six articles that belong to the field of aerodynamics. This accords well with one of the declared purposes of this series, to serve the general reader with accounts of those parts of the subject remote from his specialized interest, not only because his field of specialization is likely to change during his career but also because we are all students of one science. The first paper gives a comprehensive survey of low-speed wind-tunnels, those early tools of the aerodynamicist which seem likely to retain their importance indefinitely. The second deals with a basic feature of the separation of a laminar boundary layer from a wall in two-dimensional flow: the bubble. The third reports on the more theoretical aspects of the IUTAM Symposium Transsonicum, which afforded a reunion of almost everyone who at one time or another had contributed to our knowledge of flows of mixed type. The fourth paper is concerned with a particular aspect of the theory of transonic flows and gives an exhaustive survey of this work. The fifth paper reports on a symposium devoted to rarefied gas dynamics. The final paper presents corrections to an article on the theory of sonic bangs, published in Volume 1 of this series.

Progress in Aeronautical Sciences, Volume 9 presents the vibrational characteristics of certain aircraft. This book supplements the comprehensive account of matrix methods of structural analysis. Organized into five chapters, this volume begins with an overview of the different schemes of the numerical method of characteristics for calculating three-dimensional steady supersonic gas flow about bodies moving at incidence. This text then examines the flow of a perfect gas and provides the generalization for the case of equilibrium and non-equilibrium flow of real gas. Other chapters consider the various aspects of the aerodynamic design of aircraft and discuss the application of modern computer methods to fluid mechanics. This book discusses as well the prospects for further development of the existing types and for the establishment of the as yet hypothetical types of aircraft. The final chapter shows how the evolution of the aerodynamic shape leads to a complete spectrum of major types of aircraft. This book is a valuable resource for engineers.

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.

Advances in Aeronautical Sciences, Volume 1 contains the proceedings of the First International Congress in the Aeronautical Sciences, held in Madrid, Spain in September 1958. The book is comprised of survey papers and original contributions that discuss common problems in aeronautics and in space technology. The reader will also find interesting articles that cover topics on the principles of inertial guidance; boundary layer control; VTOL/STOL aircraft; heat resisting material; heat transfer and heat barrier; and jet noises and human factors in aeronautics. Hypersonic speeds; propulsion methods in space and magneto-fluid dynamics are discussed as well. Aeronautics engineers and scientists in allied fields will find the book insightful.
