Book Synopsis Spinning Flight by : Ralph D. Lorenz
Download or read book Spinning Flight written by Ralph D. Lorenz and published by Springer Science & Business Media. This book was released on 2007-02-02 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: More frisbees are sold each year than baseballs, basketballs and footballs combined. Yet these familiar flying objects have subtle and clever aerodynamic and gyrodynamic properties which are only recently being documented by wind tunnel and other studies. In common with other rotating bodies discussed in this readily accessible book, they are typically not treated in textbooks of aeronautics and the literature is scattered in a variety of places. This book develops the theme of disc-wings and spinning aerospace vehicles in parallel. Since many of the examples are recreational, anyone who enjoys these activities will likely find it profitable and enjoyable. In addition to spinning objects of various shapes, several exotic manned aircraft with disc planforms have been proposed and a prototypes built – these include a Nazi ‘secret weapon’ and the De Havilland Avrocar, also discussed in the book. Boomerangs represent another category of spinning aerodynamic body whose behavior can only be understood by coupling aerodynamics with gyrodynamics. The narrative, supported by equations and graphs, explains how the shape and throw of a boomerang relates to its trajectory. The natural world presents still other examples, namely the samaras or ‘seed-wings’ of many tree species, which autorotate during their descent, like a helicopter whose engine has failed. The flight performance of these spinning wings directly affects the dispersal and thus the evolutionary competitiveness of the trees concerned. Samara-type configurations are also considered for instrumentation and other payload dispersal applications. In short, the book discusses a range of familiar, connected, but largely undeveloped, topics in an accessible, but complete, manner. From the reviews of the first edition: "In his fascinating book Spinning Flight, Ralph Lorenz provides a rich feast of ... examples of spinning bodies ... . The book is well organized ... . The discussion in the book ... should be accessible to readers with some elementary understanding of aerodynamic principles. For the expert, the book is full of open problems ... . Its scope is extensive ... . In this respect, there may be something for everyone within its attractively designed cover ... ." (H. K. Moffatt, Nature, Vol. 444, December, 2006) "If you liked physics at school, then this book is for you. It concerns itself with flying objects that spin through the air, and even tells you how to impress your friends with the biomechanics of Frisbees. ... there is plenty of information at all levels, and the book has a wealth of detail that only an aerospace engineer like Lorenz could have come up with." (Len Fisher, BBC Focus, February, 2007)

Book Synopsis The Paper Boomerang Book by : Mark Latno
Download or read book The Paper Boomerang Book written by Mark Latno and published by Chicago Review Press. This book was released on 2010-06-01 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: When it comes to lightweight avionics, there's no beating a paper boomerang. Let all the others chase after their dull folded airplanes--you can now build a flying device that comes right back to you, every time! And unlike expensive, heavy wooden boomerangs, you won't endanger windows and skulls with paper boomerangs. The Paper Boomerang Book is the first-of-its-kind guide to this fascinating toy. Expert Mark Latno not only tells you how to build, perfect, and troubleshoot your paper boomerang, but about the 20,000-year history of the device, including Egyptian throwing sticks found in pharaoh's tombs, and the physics behind their circuitous flights. And once you've mastered the basic throw, return, and catch, it's on to more impressive tricks--the Behind-the-Back Toss, the Boomerang Juggle, the Under-the-Leg Catch, and the dreaded Double-Handed, Backward, Double-Boomerang Throw. For those who don't have the luxury of the wide-open outback on a clear Australian day, author Latno includes plans for Little Dragons, miniature versions of the paper boomerang that can be used indoors in almost any sized room, rain or shine.

Download or read book Applied Aerodynamics written by Jorge Colman Lerner and published by BoD – Books on Demand. This book was released on 2012-05-11 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aerodynamics, from a modern point of view, is a branch of physics that study physical laws and their applications, regarding the displacement of a body into a fluid, such concept could be applied to any body moving in a fluid at rest or any fluid moving around a body at rest. This Book covers a small part of the numerous cases of stationary and non stationary aerodynamics; wave generation and propagation; wind energy; flow control techniques and, also, sports aerodynamics. It's not an undergraduate text but is thought to be useful for those teachers and/or researchers which work in the several branches of applied aerodynamics and/or applied fluid dynamics, from experiments procedures to computational methods.

Book Synopsis Golf Balls, Boomerangs and Asteroids by : Brian H. Kaye

Available in PDF, EPUB and Kindle. Book excerpt: Exciting reading for anyone with a curious mind! 'Walking one day by a golf course in Wisconsin, I was startled to hear a sharp bang as a golf ball narrowly missed my head and hit a tree. My companion cheerfully remarked, 'That could have killed you, you know.' I picked up the innocent looking little white ball and looked at it with new respect.' Prompted by this perilous experience, Brian Kaye has written a delightful and informative book on the design and behavior of different kinds of missiles from golf balls, arrows, and slingshots to comets and rockets to outer space. You'll learn about the science of tennis and find the answer to questions like why a golf ball has dimples or why a boomerang comes back. Don't miss Brian Kaye's latest, you'll be amused and amazed - and learn some physics to boot.
Book Synopsis Principles and Simulation of the Flight of a Straight Boomerang by : Nicolás Restrepo
Download or read book Principles and Simulation of the Flight of a Straight Boomerang written by Nicolás Restrepo and published by . This book was released on 1995 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: "There has been a lot of research done on the regular boomerang but little or none has ever been done on the straight boomerang. This not so popular toy does behave as a boomerang but the physics governing its flight are very different from those governing the regular boomerang's flight. In order to understand what makes the straight boomerang come back, high speed photography was used. It was concluded that the autorotation phenomenon played an important role during the flight. A mathematical model was then developed and the flight dynamics of the boomerang incorporating its actual behavior was simulated using MATLAB. The simulation results obtained were very close to those obtained from experimentation."--Abstract.
