Book Description
This book tells the tale of the brilliant aerodynamicist Beverley Shenstone MASc, HonFRAes, FAIAA,AFIAS, FCASI, HonOSTIV. As R.J. Mitchell's chief aerodynamicist, it was Shenstone who designed the Spitfire's wing - the wing that gave the Spitfire it crucial advantage in the Battle of Britain and beyond. A quiet man, Shenstone never sought glory for his work, yet in recent years he has been credited as the man who persuaded Mitchell to adopt the ellipse - a modified ellipse that was unique in its shape and its combined use of two integrated aerofoil sections. Shenstone's knife-edge shape reached far back into early aeronautics for its inspiration. This book also names the other forgotten Spitfire design contributors who were Mitchell's men - Mr Faddy, Mr Fear, Mr Fenner, Mr Shirvall, a Prof Howland and others. Intriguingly, Shenstone had left his native Canada and early training as an RCAF pilot, to study at Junkers and then under the father of the delta wing - Alexander Lippisch in Germany in the early 1930s. There, he became immersed in delta wings and flying wings. He also became a glider pilot. The story of how Beverley came to be in the right place at the right time is revealed for the first time. So too are the enigmatic tales of his involvement with the military, the intelligence world, Lord Beaverbrook , the USAF, and Canadian aviation. During the war Shenstone worked at the top secret Wright Patterson air force base and was involved with the Air Ministry and the pro-British movement in America when Shenstone worked for Air Chief Marshal Sir Wilfrid Freeman, the unsung hero behind British defence procurement. Shenstone achieved high office - a President of the Royal Aeronautical Society, technical director at BOAC, chief engineer at BEA and a consultant to several aircraft makers. He was courted by Avro, de Havilland and Vickers, and was the force behind the renaissance of human-powered flight. Using exclusive access to his family documents, his unpublished autobiography and many notes and stories, as well as forensic research, this book details for the first time, a new twist to the Spitfire's story and the secrets of its advanced science. A tale of design and military intelligence reveals a story of a man whose name should be more widely known in the UK, Canada and the aviation world. SELLING POINTS: * Illustrated throughout * Evokes a golden age of aviation design and development * Relay's the story of one of History's most overlooked heroes of aviation design ILLUSTRATIONS: 20 mono photos

Book Description
There are many myths and legends surrounding the advanced German aeronautical technology of the Second World War. There are also facts and proven events. Yet within these stories and behind these facts lie conspiracy theories, mistaken assumptions and denials that seem to contradict the evidence. So what really happened? How far ahead were the German scientists? And, of even greater interest, why and how?There have been other books about advanced German wartime aeronautics, yet few authors have fully examined the detail of the designs and their relevance to the fighter and bomber legends of the 1950s and '60s, let alone the current crop of military and civil all-wing or blended-wing aircraft. This book charts the story from it origins, through current-day innovations and beyond, into the all-wing future of tomorrow.

"Skylar Crosby knows betrayal. She knows that deep stab when those closest to you deceive your fragile trust. And she knows what it's like when your secrets cost you everything--including the love of your life. Now kidnapped, scared, and alone, Skylar has no reason to believe in her rescue. Not when she can still see Brandon's face as she smashed his heart to pieces. Even if Skylar can get out of her physical prison, can she escape the cage created by her guilt? Brandon Sterling spent the last fifteen years desperately trying to reinvent himself: as a lawyer, a businessman, and now a candidate for public office. But as these daily stressors mount alongside a dangerous threat to his family and loved ones, the old Brandon reemerges: a ruthless hoodlum who'd rather use fists than brains to solve his problems.

Book Description
THE SUNDAY TIMES BESTSELLER 'An inspirational read celebrating the incredible young people who gave so much for this iconic British aircraft'. John Nichol, bestselling author of Spitfire: A Very British Love Story Despite the many films and television programmes over the decades since the end of the Second World War that portrays our allied heroes as grown-up men and women, the Battle of Britain was in the main actually fought and won by teenagers. The average age of an RAF fighter pilot was just twenty years old. Many of the men and women who designed and built their planes were even younger. Based on the hit BBC World Service podcast Spitfire: The People's Story, we use contemporary diaries and memoirs, many of them previously unpublished, to tell the story of the Spitfire through the voices of the teenagers who risked everything to design, build and fly her. This isn't a story of stiff-upper lips, stoical moustaches and aerial heroics; it's a story of love and loss, a story of young people tested to the very limits of their endurance. Young people who won a battle that turned a war.

Category : History
Languages : en
Pages : 480
Book Description
The piston engines that powered Second World War fighters, the men who designed them, and the secret intelligence work carried out by both Britain and Germany would determine the outcome of the first global air war. Advanced jet engines may have been in development but every militarily significant air battle was fought by piston-engined fighters. Whoever designed the most powerful piston engines would win air superiority and with it the ability to dictate the course of the war as a whole. This is the never before told story of a high-tech race, hidden behind the closed doors of design offices and intelligence agencies, to create the war's best fighter engine. Using the fruits of extensive research in archives around the world together with the previously unpublished memoirs of fighter engine designers, author Calum E. Douglas tells the story of a desperate contest between the world's best engineers - the Secret Horsepower Race.
