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.

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.

Wings carry tiny insects, fluttering butterflies, and backyard birds, and they even once propelled some dinosaurs up and through the skies. Find out how, when, and why birds and beasts have taken to the air, and discover how wings work in this informative and brilliantly illustrated book about flight.

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.

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.

For anyone interested in the aerodynamics, structural dynamics and flight dynamics of small birds, bats, insects and air vehicles (MAVs).

The book focuses on the synthesis of the fundamental disciplines and practical applications involved in the investigation, description, and analysis of aircraft flight including applied aerodynamics, aircraft propulsion, flight performance, stability, and control. The book covers the aerodynamic models that describe the forces and moments on maneuvering aircraft and provides an overview of the concepts and methods used in flight dynamics. Computational methods are widely used by the practicing aerodynamicist, and the book covers computational fluid dynamics techniques used to improve understanding of the physical models that underlie computational methods.

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.
