Available in PDF, EPUB and Kindle. Book excerpt: Dynamic Soaring Dissected Albatrosses fly over the oceans in swooping, curving flight gliding thousands of kilometres in search of food, mostly without flapping their wings. This is known as dynamic soaring, which is the use of the energy of the horizontal wind to sustain speed and height. It is different from the soaring flight of most other birds and gliders which use the vertical motion of the air to maintain or gain height. Since the 1880's, a time before manned gliding flight had been achieved, the mechanism of dynamic soaring has been poorly explained by the Rayleigh cycle or the wind gradient theory. However, there is more to dynamic soaring than the wind gradient and furthermore, the true nature of albatross flight has only recently been revealed by filming and GPS tracking. Dynamic Soaring Dissected takes up the discussion where it was left in the 19th century and explains how aircraft and birds fly. It looks at albatross flight through the lens of electronic tracking and takes us on a foraging trip with an albatross in long-distance soaring flight. In the Windward Turn Theory, it describes the mechanism of dynamic soaring and the hidden effect of the wind on a bird or an aircraft in flight. It explains the way that albatrosses are able to turn this effect to their advantage and how they are able to dynamic soar crosswind, upwind and downwind. It also describes how radio-control gliders can achieve huge speeds in circling flight and settles the perennial debate on the Myth of the Downwind Turn and what really happens when an aircraft turns downwind and ends up in a stall and spin accident.

Available in PDF, EPUB and Kindle. Book excerpt: Knowledge is not merely everything we have come to know, but also ideas we have pondered long enough to know in which way they are related, and 1 how these ideas can be put to practical use. Modern aviation has been made possible as a result of much scienti c - search. However, the very rst useful results of this research became ava- able a considerable length of time after the aviation pioneers had made their rst ights. Apparently, researchers were not able to nd an adequate exp- nation for the occurrence of lift until the beginning of the 21st century. Also, for the fundamentals of stability and control, there was no theory available that the pioneers could rely on. Only after the rst motorized ights had been successfully made did researchers become more interested in the science of aviation, which from then on began to take shape. In modern day life, many millions of passengers are transported every year by air. People in the western societies take to the skies, on average, several times a year. Especially in areas surrounding busy airports, travel by plane has been on the rise since the end of the Second World War. Despite becoming familiar with the sight of a jumbo jet commencing its ight once or twice a day, many nd it astonishing that such a colossus with a mass of several hundred thousands of kilograms can actually lift off from the ground.

Available in PDF, EPUB and Kindle. Book excerpt: This book is concerned with the sport of soaring, mainly with the mathematical basis of sailplane design and operation. It does not tell the beginner how to fly, but it will give an experienced pilot some background, with historical notes showing how ideas have evolved and could develop in the future. Some of the material is taken from OSTIV (Organisation Scientifique et Technique Internationale de Vol a Viole) publications and from Technical Soaring, neither of which is readily available to the general public, including papers by the author and others. Extensive references are provided in each chapter.

Download or read book Downwind Faster Than the Wind written by Nicholas Landell-Mills and published by . This book was released on 2021-08-02 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: New analysis shows how Newton and Galileo provide a straightforward and useful explanation of sailing. According to Newton, the sail re-directs a mass of air of the apparent wind backwards to create a backward force (Force = ma). The reactive equal and opposite forward force pushes the sailboat ahead. According to Galileo a boat can sail downwind faster than the wind for the same reasons that it can sail upwind faster than the wind. Each tack is simply the mirror image of the other one. This is because in both situations the sailboat experiences a headwind, and the true wind is moving backwards relative to the boat. When sailing both upwind and downwind, the sail extracts momentum and energy from the true wind by slowing it down. That's it.

Available in PDF, EPUB and Kindle. Book excerpt: This investigation attempts to surpass the boundaries of pure mathematical interest in that it possesses as an example, a flow investigation in a multiply-connected region. Then the results appear to be carried out by means of an appropriate conformal representation of the region around two chosen closed curves. Thus we have the basis of an exact plane theory of the biplane. Certainly, the known difficulties of the accomplishment of this representation depend upon the region around the given curves. It is easier to choose the transformation function so that we obtain the transformal curves which, as contours of the wings of a biplane are at least useful to a certain extent, and correspond to the Joukowski monoplane wing.

Download or read book Modelling the Flying Bird written by C.J. Pennycuick and published by Elsevier. This book was released on 2008-08-23 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book outlines the principles of flight, of birds in particular. It describes a way of simplifying the mechanics of flight into a practical computer program, which will predict in some detail what any bird, real or hypothetical, can and cannot do. The Flight program, presented on the companion website, generates performance curves for flapping and gliding flight, and simulations of long-distance migration and accounts successfully for the consumption of muscles and other tissues during migratory flights. The program is effectively a working model of a flying bird (or bat or pterosaur) and is the skeleton around which the book is built. The book provides a wider background and then explains how Flight works and shows how to set up and test hypotheses generated by the program.The book and the program are based on adapting the conventional (and well-tested) thinking of aeronautical engineers to the biological problems of bird flight. Their primary aim is to convince biologists that this is the appropriate way to handle problems that involve flight, to make the engineering background accessible to biologists, and to provide a tool kit in the shape of the Flight program, which they can use to solve practical problems involving bird flight and migration. In addition, the book will be readily accessible to engineers who want to know how birds work, and should be of interest to the ever-growing community working on flapping "micro air vehicles" (MAVs). The program can be used to predict the flight performance and capabilities of reconstructed fossil birds and pterosaurs, flying in ancient atmospheres that differ from present conditions, and also, of course, to predict and account for the results of experiments and observations on living birds and bats.* An up to date work by the world's leading expert on bird flight* Examines the biology and biomechanics of bird flight with added reference to the flight of bats and pterosaurs.* Uses proven aeronautical principles to help solve biological issues in understanding and predicting the flight capabilities of birds and other vertebrates.* Provides insights into the evolution of flight and the likely capabilities of extinct birds and reptiles.* Gives a detailed explanation of the science behind, and use of, the author's predictive bird flight simulation program - Flight - which is available on a companion website.* Presents often difficult concepts in easily understood language.
