| Aerofoil Sections: Results from Wind-Tunnel Investigations,Theoretical Foundations By Friedrich Wilhelm Riegels
Description: Forewords, excerpted from both the original German, and English traslation During the last fifty years fluid dynamics has become indispensable in the solution of industrial problems, particularly those associated with aviation. Technology has advanced so rapidly that, to meet its demands, research on a gigantic scale is necessary. A regrettable consequence of this is that advances in the field of fluid dynamics have become too numerous for one person to be able to survey them. There is therefore a pressing need for surveys of the various branches, so that a reader can obtain a view of the whole subject and can be informed on the questions of greatest importance. Unfortunately, little has been accomplished in this direction; the chief reason is that few workers have a real mastery of their field. Consequently, this book is most welcome, since it provides a clear and comprehensive survey of the subject of wing profiles. It is highly desirable that similar books should be written on other subjects. Albert Betz Gottingen, October,1956 Dr. Riegels's book was written with the needs of German workers in mind, yet it should appeal to a much wider cIrcle of readers. Our knowledge of a scientific subject is never complete, but further advances in the subject of wing profiles are likely to be small-scale; therefore, a book that surveys all the main theories and discusses many of the experimental investigations should be most valuable. Not the least useful part of the book is the large amount of tabular and graphical information on the geometrical and aerodynamic characteristics of profiles. In times when slenderness is such a desirable attribute of wings, and supersonic speeds are commonplace, there is a tendency to think of low-speed, two-dimensional flow as an outdated topic. It is forgotten that the subject is still of importance: it is continually required in the design of ship propellers, turbines, and compressors; and it is still of use for a wide variety of aircraft, ranging from gliders to model aeroplanes. I wish to thank many of my colleagues at the Royal Aircraft Establishment (not all of them German-born) for their ready help. It is a pleasure to express my gratitude to Mrs. W. T. Lord for performing the secretarial work so competently. D. G. Randall Farnborough, February, 1960 | |
