Download or read book Flutter at Very High Speeds written by Harry L. Runyan and published by . This book was released on 1961 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper is concerned with a discussion of some of the problems of flutter and aeroelasticity that are or may be important at high speeds. Various theoretical procedures for treating high Mach number flutter are reviewed. Application of two of these methods, namely, the Van Dyke method and piston-theory method, is made to a specific example and compared with linear two- and three-dimensional results. It is shown that the effects of thickness and airfoil shape are destabilizing as compared with linear theory at high Mach number. In order to demonstrate the validity of these large predicted effects, experimental flutter results are shown for two rectangular wings at Mach numbers of 6.86 and 3. The results of nonlinear piston-theory calculations were in good agreement with experiment, whereas the results of using two- and three-dimensional linear theory were not. In addition, some results demonstrating the importance of including camber modes in a flutter analysis are shown, as well as a discussion of one case of flutter due to aerodynamic heating.

Download or read book Sound Hearing written by R. Duncan Luce and published by Psychology Press. This book was released on 2013-10-31 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: The major aim of this book is to introduce the ways in which scientists approach and think about a phenomenon -- hearing -- that intersects three quite different disciplines: the physics of sound sources and the propagation of sound through air and other materials, the anatomy and physiology of the transformation of the physical sound into neural activity in the brain, and the psychology of the perception we call hearing. Physics, biology, and psychology each play a role in understanding how and what we hear. The text evolved over the past decade in an attempt to convey something about scientific thinking, as evidenced in the domain of sounds and their perception, to students whose primary focus is not science. It does so using a minimum of mathematics (high school functions such as linear, logarithmic, sine, and power) without compromising scientific integrity. A significant enrichment is the availability of a compact disc (CD) containing over 20 examples of acoustic demonstrations referred to in the book. These demonstrations, which range from echo effects and filtered noise to categorical speech perception and total more than 45 minutes, are invaluable resources for making the text come alive.

Book excerpt: This third edition, in the same tradition as the second, is a vital servicing tool containing information covering virtually every motorcycle over 50cc sold in the UK since 1980. The author is technical editor of `Performance Bikes' and author of the well known `Motorcycle Tuning' books. The book provides access to the most frequently used data for dealers, mechanics and enthusiasts who have to deal with a wide variety of machines and wish to compare the features of different models. A seperate section lists conversion tables, standard torque settings for threaded fasteners, tyre size codes, tyre speed and load schedules and addersses of importers. Machines are listed alphabetically by manufacturer and then in order of capacity or model number.
