Book Description
By the mid-1930s the obstacles to high speed that aircraft designers faced included the question of cooling the engine. This was a big challenge that those working on the new fast aeroplanes entering service as the war clouds gathered over Europe had to consider, as the drag from the system increased as a square of the speed. Ducted systems were designed which lowered drag, but these were based on the assumption that the system was cold. This ignored the potential energy from the air, heated by the radiator, for liquid-cooled aircraft, and from the discharged engine exhaust gases. It took a profoundly lateral thinker to harness the possibilities of the paradox that heat could cut the cost of cooling. That thinker was the British engineer Frederick William Meredith. A researcher at the Royal Aircraft Establishment at Farnborough until 1938, F.W. Meredith a key player in the UK’s development of the autopilot and remote-controlled aircraft. His contribution to Allied success in the Second World War was enormous – but, incredibly, he was also a known a Soviet agent. Few would doubt that the Supermarine Spitfire was a pioneering aeroplane – not because it was an all metal, monoplane with retractable undercarriage and enclosed cockpit as these were not unique – but because it was the first to incorporate a Meredith designed ducted cooling system. This was intended from the beginning to use heat to create ‘negative drag’. In practice the Spitfire’s design was flawed, as Meredith himself pointed out, and did not fully use what became known as the ‘Meredith Effect’. Meredith also made entirely overlooked but extremely important contributions to resolving the problem of how to induce air smoothly into cooling ducts at high speeds without which, as the Spitfire demonstrated, ducted cooling systems worked sub-optimally. The first aeroplane properly to exploit the ‘Meredith Effect’ was the North American P-51 Mustang, this being a very significant factor as to why it was 30mph faster than the Spitfire when both had the same Rolls-Royce Merlin engine. This book by Peters Spring examines the life of the remarkable, and controversial, F.W. Meredith, an individual who has largely been forgotten by history despite the brilliant advances he made – advances which helped the Allies win the war against Hitler’s Third Reich.

Book Description
This book tells the tale of the brilliant aerodynamicist Beverley Shenstone MASc, HonFRAes, FAIAA,AFIAS, FCASI, HonOSTIV. As R.J. Mitchells chief aerodynamicist, it was Shenstone who designed the Spitfires 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. Shenstones knife-edge shape reached far back into early aeronautics for its inspiration. This book also names the other forgotten Spitfire design contributors who were Mitchells 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 Spitfires 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.

Book Description
During World War II, the United States Army Air Corps was led by a cadre of officers who believed implicitly that military aviation, particularly fast heavy bombers at high altitude, would be able to destroy strategic enemy targets during daylight with minimal losses. However, by 1942 the Flying Fortress was proving vulnerable to Luftwaffe fighters. This title charts the United States Army Air Force's struggle to develop a Long-Range Escort which would enable them to achieve the Combined Bomber Objectives and gain mastery of the skies over the Third Reich. The commitment of the USAAF to the Mediterranean and European theatres saw an increasingly desperate need to find a fighter escort, which reached crisis point in 1943 as losses suffered in the Tidal Wave offensive and Schweinfurt-Regensburg-Munster raids emphasised the mounting strength of the Luftwaffe. The USAAF leaders increasingly accepted the probability of bomber losses, and the deployment of the P-51B Mustang solved the problem of Germany's layered defence strategy, as Luftwaffe fighters had been avoiding the P-47 Thunderbolt and P-38 Lightening escort fighters by concentrating their attacks beyond the range of the Thunderbolt and Lightning. The P-51B duly emerged as the 'The Bastard Stepchild' that the USAAF Material Division did not want, becoming the key Long-Range Escort fighter, alongside the P-38 and P-47, that defeated the Luftwaffe prior to D-Day. As well as the P-51B's history, this title explores the technical improvements made to each of these fighters, as well as the operational leadership and technical development of the Luftwaffe they fought against.

Book Description
The 25 Most Influential Aircraft of All Time conveys the fascinating progression of flying technology from flimsy wood-and-fabric biplanes to thunderous supersonic wonders. Aviation’s most historically relevant and arguably most influential aircraft – planes like the elliptical-winged Spitfire, the blisteringly-fast X-15, and the ubiquitous Learjet – are dramatically showcased in individual chapters. Factors like performance, price, operational efficiency, and perceptions in popular culture are examined. People are just as important as hardware in the discussion of the world’s greatest aircraft. The larger-than-life characters who designed and built these aeronautical marvels – men like the reclusive Howard Hughes and the demanding Clarence “Kelly” Johnson – are an indispensable part of the story. So, too, are the fearless pilots like Charles Lindbergh and Chuck Yeager who gave life to the shining examples of a new and dynamic industry. The authors have flown or flown in many of the featured aircraft and they knew many of the luminous personalities involved, enabling them to share unique perspectives. The preface is written by William Lloyd Stearman, a former staff member of the National Security Council and the son of famed industry engineer Lloyd Stearman. The introduction is written by Norman R. Augustine, the retired Chairman and CEO of Lockheed Martin Corporation. The foreword is written by Burt Rutan, the renowned aircraft designer and founder of Scaled Composites. Each aircraft is magnificently illustrated in color, mostly with paintings by leading aviation artists.

Book Description
Explore the WWII history of the company that later became a part of Boeing and made more aircraft from 1938 to 1944 than any other company in the United States. During World War II, Los Angeles was the ultimate boom town. By the end of the war, the L.A. area had produced 17 percent of all of America's war needs. North American Aviation, Inc. (NAA), operating out of their main Inglewood, California, plant, which is south of and adjacent to the city, was a key player in that work. From 1938 to 1944, NAA built over 40,000 aircraft, more than any other company in the United States. The bulk of them were of three iconic types designed by NAA: - The P-51 Mustang, arguably the best fighter of WWII. - B-25 Mitchell medium bombers, which saw worldwide combat. - Two-seat military pilot trainers, such as the AT-6 Texan. This is a fascinating story of a remarkable time in aviation history, when American businesses helped fund the arsenal of democracy that helped defeat the Axis powers. Warbird Factory tells this story with over 200 photographs, many of which come directly from the NAA/Boeing archives, where they have resided since WWII. This is an essential book for anyone interested in warbirds, aviation, Boeing/NAA, WWII, and/or the history of Southern California!
