Download or read book In Hovering Flight written by Joyce Hinnefeld and published by Unbridled Books. This book was released on 2009-09-01 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: At 34, Scarlet Kavanagh has the kind of homecoming no child wishes, a visit back to family and dear friends for the gentle passing of her mother, Addie, a famous bird artist and an even more infamous environmental activist. Though Addie and her husband, ornithologist Tom Kavanagh, have made their life in southeastern Pennsylvania, Addie has chosen to die at the New Jersey home of her dearest friend, Cora. This is because the Kavanagh’s ramshackle cottage is filled with too much history and because, in the last ten years or so, and for reasons that are not entirely clear, even bird song has seemed to make Addie angry, or sad, or both. Now, in their final moments together, Scarlet hopes to put to rest the last tensions that have marked their relationship. Through tender conversations with Cora and Lou, another of Addie’s dear friends, Scarlet slowly comes to peace with her mother’s complicated life. But can she do the same with her own? Scarlet has carried a secret into these foggy days - a secret for Addie, one that involves Cora, too. In its structure and style this novel follows in the tradition of writers like Virginia Woolf, Harriet Doerr, and Carol Shields: musical and dramatic, with myriad stories and voices. But the evocative language of this soaring novel is Hinnefeld’s own.

Download or read book Swimming and Flying in Nature written by Theodore Wu and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Symposium on Swimming and Flying in Nature which was held at the California Institute of Technology, Pasadena, California from July 8-12, 1974 was conceived with the objective of providing an interdisciplinary forum for the discussion of funda mental biological and fluid mechanical aspects of these forms of natura110comotion. It was the earnest hope of all concerned in the organization of the Symposium that the exchange of knowledge and interaction of ideas from the disciplines involved would stimu late new research in this developing field. If the liveliness of the discussion generated among the 250 or so participants is any measure, then this objective was fulfilled to a significant degree. These two companion volumes contain the manuscripts of the papers presented during the Symposium. It is hoped that this permanent record will serve to perpetuate the enthusiasm and active thought generated during those days in Pasadena. The first volume contains the proceedings of the first two days of the confer ence (Sessions I to IV) which concentrated on the locomotion of micro-organisms. The second volume (Sessions V to VIII) deals with the propulsion of larger fish, insects and birds. Professor Sir James Lighthill's Special Invited Lecture which opened the Symposium is contained in the second volume, rather than the first, since it deals with natural flight.
Download or read book Biophysics of Insect Flight written by N. Chari and published by Springer Nature. This book was released on 2022-01-04 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book basically involves the study of flight parameters, wing beat frequency, moment of inertia, and wing movements for developing various aerodynamic forces which have been calculated. The book is intended for biologists, physicists, nanotechnologists, and aerospace engineers. Resilin, an elastic polymer (4 λ) which is present at the base of insect, plays a major role in Neurogenic and Myogenic insect flyers and influences the physiology of flight muscles. Leading edge vortex (LEV) is a special feature of insect flight. Insect wings have stalling angle above 60 degrees as compared to a man-made aeroplane stalling angle which is 16 degree. Reynolds number, the knowledge of LEV, and detailed study of moment of inertia help in developing flapping flexible wings for micro-aerial-vehicles. This book serves as an interface between biologists and engineers interested to develop biomimicking micro-aerial-vehicles. The contents of this book is useful to researchers and professionals alike.

Download or read book Hovering Flight Tests of a Four engine transport Vertical Take off Airplane Model Utilizing a Large Flap and Extensible Vanes for Redirecting the Propeller Slipstream written by Louis P. Tosti and published by . This book was released on 1955 with total page 692 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation of the take-off, landing, and hovering-flight characteristics of a four-engine-transport, vertical take-off airplane has been conducted with a remotely controlled free-flight model. The model had four propellers distributed along the wing with thrust axes parallel to the fuselage axis. In order to produce direct lift for hovering flight, the propeller slipstream was deflected downward about 70 degrees by a full-span 65-percent-chord flap deflected 90 degrees and eight extensible vanes arranged above the wing in a cascade relation.

Download or read book An Introduction to Flapping Wing Aerodynamics written by Wei Shyy and published by Cambridge University Press. This book was released on 2013-08-19 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is an ideal book for graduate students and researchers interested in the aerodynamics, structural dynamics and flight dynamics of small birds, bats and insects, as well as of micro air vehicles (MAVs), which present some of the richest problems intersecting science and engineering. The agility and spectacular flight performance of natural flyers, thanks to their flexible, deformable wing structures, as well as to outstanding wing, tail and body coordination, is particularly significant. To design and build MAVs with performance comparable to natural flyers, it is essential that natural flyers' combined flexible structural dynamics and aerodynamics are adequately understood. The primary focus of this book is to address the recent developments in flapping wing aerodynamics. This book extends the work presented in Aerodynamics of Low Reynolds Number Flyers (Shyy et al. 2008).
Download or read book The Biokinetics of Flying and Swimming written by Akira Azuma and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: From a mechanical perspective, an animal's shape and the topological connection of its organs are important factors in locomotion. This book describes the physical relationships between form, habitat, way of life, and movement in living creatures. It includes in-depth mechanical and mathematical analyses of the way in which creatures move about, and it also investigates dispersal modes of plants and animals within the framework of flying and swimming. The book is written from the viewpoint of mechanics, specifically fluid dynamics and flight dynamics, rather than from that of physiology and ecology. It will prove a useful reference for aeronautical and mechanical engineers as well as for biologists who use mechanical analyses in the study of behaviour, function, and locomotion.
Download or read book Contact Flying written by Jim Dulin and published by Contact Flying. This book was released on 2008-05 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unlike conventional aviation authors and instructors I do not teach primary flying, crop dusting, pipeline patrol flying, bush flying, helicopter medical evacuation flying, and air to ground gunnery using instruments inside the aircraft as the primary situational awareness tool. Rather I teach Dutch rolls, slow flight and stalls over the runway, the energy management turns, use of ground effect on all takeoffs, the brisk walk apparent rate of closure approach, hover taxi in fixed wing aircraft, and low level low power mountain flying using sights, sounds, smells, and kinetics. Sight is used 99.9% of the time looking at the ground. Airspeed, nor any other instrument is used in takeoff or landing. This text teaches the art of flying in the old style at low level using ground references. Its author has over sixteen thousand hours of flying Army helicopters, crop dusters, and pipeline patrol airplanes at three feet to five hundred feet above ground level.
Download or read book Band pass Shock and Vibration Absorbers for Application to Aircraft Landing Gear written by Emanuel Schnitzer and published by . This book was released on 1956 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new class of frequency-selective shock absorbers called band-pass shock absorbers which were conceived as a means of overcoming some of the limitations of conventional shock absorbers is described. These shock absorber designs are introduced, special emphasis being given to their use in landing and taxiing problems of high-speed aircraft. For such aircraft operated on rough land or water runways, conventional oleo struts approach a rigid condition for bum[s with steep slopes and thereby develop and transmit severe shock loads to the aircraft fuselage. The operation of the band-pass shock absorbers in the reduction of loads in certain selected frequency ranges is described. Theoretical equations are derived and solutions are made for several cases for the purpose of comparing the low-pass and conventional shock-absorber actions. The results indicate that the band-pass shock absorbers should alleviate high-frequency or rapidly applied impact loads but should retain the characteristics of conventional oleo struts when taxiing and design landing loads are slowly applied. A number of variations in design are presented for low-pass shock absorbers and reference is made to double-acting band-pass vibration absorbers for other applications.
Download or read book The Biomechanics of Insect Flight written by Robert Dudley and published by Princeton University Press. This book was released on 2018-06-05 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the rain forests of Borneo to the tenements of Manhattan, winged insects are a conspicuous and abundant feature of life on earth. Here, Robert Dudley presents the first comprehensive explanation of how insects fly. The author relates the biomechanics of flight to insect ecology and evolution in a major new work of synthesis. The book begins with an overview of insect flight biomechanics. Dudley explains insect morphology, wing motions, aerodynamics, flight energetics, and flight metabolism within a modern phylogenetic setting. Drawing on biomechanical principles, he describes and evaluates flight behavior and the limits to flight performance. The author then takes the next step by developing evolutionary explanations of insect flight. He analyzes the origins of flight in insects, the roles of natural and sexual selection in determining how insects fly, and the relationship between flight and insect size, pollination, predation, dispersal, and migration. Dudley ranges widely--from basic aerodynamics to muscle physiology and swarming behavior--but his focus is the explanation of functional design from evolutionary and ecological perspectives. The importance of flight in the lives of insects has long been recognized but never systematically evaluated. This book addresses that shortcoming. Robert Dudley provides an introduction to insect flight that will be welcomed by students and researchers in biomechanics, entomology, evolution, ecology, and behavior.
