Division II: Aerodynamics, Volume 7: Wing Theory in Supersonic Flow examines the cases of isolated simple wings, wings with vertical plane tail, cruciform wings, and simple or cruciform wings fitted with a body. This book presents the method for the actual calculation of isolated wings or of more complex system. Organized into 12 chapters, this volume starts with an overview of the basic equations in the mechanics of inviscid fluids. This text then presents a unified theory that is established for angularly shaped wings in supersonic flow. Other chapters consider the method for calculating the characteristics of drag, lift, and moments for various shapes of the trailing edge line. This book discusses as well the wings of ordinary shapes, delta wings, yawed wings, polygonal wings, trapezoid wings, and arrow-head or swept-back wings. The final chapter deals with a delta wing with a central fusiform body. This book is a valuable resource for teachers, students, and specialists engaged in modern aerodynamics.

This book gathers contributions to the 21st biannual symposium of the German Aerospace Aerodynamics Association (STAB) and the German Society for Aeronautics and Astronautics (DGLR). The individual chapters reflect ongoing research conducted by the STAB members in the field of numerical and experimental fluid mechanics and aerodynamics, mainly for (but not limited to) aerospace applications, and cover both nationally and EC-funded projects. Special emphasis is given to collaborative research projects conducted by German scientists and engineers from universities, research-establishments and industries. By addressing a number of cutting-edge applications, together with the relevant physical and mathematics fundamentals, the book provides readers with a comprehensive overview of the current research work in the field. The book’s primary emphasis is on aerodynamic research in aeronautics and astronautics, and in ground transportation and energy as well.

A comprehensive, lavishly illustrated guide to tying popular trout flies. This book is aimed at all fly tyers, from those with modest experience to those with more advanced skills. The author’s intention is to focus on certain important elementary techniques, and then share some of his favorite contemporary twists on old, tried-and-true techniques. Many of the flies in this book are based in his own techniques and patterns, ones that he has developed in more than thirty-five years of tying. The book is arranged in sections to give readers the opportunity to easily locate the pattern or technique they are looking for. Patterns are not grouped alphabetically, but by technique. For example, the section on dry flies has categories demonstrating a particular dry fly style or technique such as mastering the use of deer hair, parachute, CDC, and so on. If you are fairly new to fly tying, the opening chapters on materials and special techniques and tricks will familiarize you with some basics and help you get started. Seasoned tyers will similarly find information here to help them raise their tying skills to a new level. Each pattern is listed with a recipe, recommended hook style, size, and materials. They are listed in the order that that author uses them, and illustrated by the book’s step-by-step images. This will help you plan each pattern and assemble materials your beforehand. Included are lushly illustrated photos for such well-known trout flies as: Pheasant tail nymph Klinkhamer Humpy Deer Hair Irresistible CDC Mayfly Spinner And much more. A special feature of this one-of-a-kind books is that its the first tying book to have a video link for all the patterns featured. Watch the author tying online, then turn to the matching chapter in the book to follow the step-by-step instructions so that you can tie your own fly in your own time. Author Barry Ord Clarke will respond online to your questions.

Fluid mechanical aspects of separated and vortical flow in aircraft wing aerodynamics are treated. The focus is on two wing classes: (1) large aspect-ratio wings and (2) small aspect-ratio delta-type wings. Aerodynamic design issues in general are not dealt with. Discrete numerical simulation methods play a progressively larger role in aircraft design and development. Accordingly, in the introduction to the book the different mathematical models are considered, which underlie the aerodynamic computation methods (panel methods, RANS and scale-resolving methods). Special methods are the Euler methods, which as rather inexpensive methods embrace compressibility effects and also permit to describe lifting-wing flow. The concept of the kinematically active and inactive vorticity content of shear layers gives insight into many flow phenomena, but also, with the second break of symmetry---the first one is due to the Kutta condition---an explanation of lifting-wing flow fields. The prerequisite is an extended definition of separation: “flow-off separation” at sharp trailing edges of class (1) wings and at sharp leading edges of class (2) wings. The vorticity-content concept, with a compatibility condition for flow-off separation at sharp edges, permits to understand the properties of the evolving trailing vortex layer and the resulting pair of trailing vortices of class (1) wings. The concept also shows that Euler methods at sharp delta or strake leading edges of class (2) wings can give reliable results. Three main topics are treated: 1) Basic Principles are considered first: boundary-layer flow, vortex theory, the vorticity content of shear layers, Euler solutions for lifting wings, the Kutta condition in reality and the topology of skin-friction and velocity fields. 2) Unit Problems treat isolated flow phenomena of the two wing classes. Capabilities of panel and Euler methods are investigated. One Unit Problem is the flow past the wing of the NASA Common Research Model. Other Unit Problems concern the lee-side vortex system appearing at the Vortex-Flow Experiment 1 and 2 sharp- and blunt-edged delta configurations, at a delta wing with partly round leading edges, and also at the Blunt Delta Wing at hypersonic speed. 3) Selected Flow Problems of the two wing classes. In short sections practical design problems are discussed. The treatment of flow past fuselages, although desirable, was not possible in the frame of this book.

In December 1943, a top secret contract (E.24/43) was awarded to Miles Aircraft. The contract was to build the world's first supersonic jet capable of 1000mph. The only reliable source of data on supersonic objects came from the Armament Research Dept and their wind tunnel tests on ammunition. From this, Miles developed an exceptionally thin-winged, bullet-shaped aircraft. the research was inexplicably passed to the Americans in 1944. By December 1945, one prototype was virtually complete. The second, destined for an attempt at the sound barrier was 80 per cent complete. In February 1946, Capt Eric Brown was confirmed as the test pilot and October 1946 was set for the supersonic trials. However, on 12 February 1946, Miles were ordered to stop production. No plausible explanation was given for the cancellation when Britain was within six months of breaking the sound barrier. Eric Brown and others directly involved including Dennis Bancroft, the Chief Aerodynamicist on the M.52, have now come together to try and finally solve the mystery behind the cancellation.

This novel of a Mississippi family in the 1920s “presents the essence of the Deep South and does it with infinite finesse” (The Christian Science Monitor). From one of the most treasured American writers, winner of a National Book Award and Pulitzer Prize, comes Delta Wedding, a vivid and charming portrait of Southern life. Set in 1923, the story is centered on the Fairchilds, a big and clamorous family, who live on a plantation in the Mississippi delta. They are in the midst of planning their daughter’s wedding when a nine-year-old relative, Laura McRaven, whose mother has just died, comes to visit. Drama leads to drama, revelation to revelation, in a novel that is “nothing short of wonderful” (The New Yorker). The result is a sometimes-riotous view of a Southern family, and the parentless child who learns to become one of them.
