Annotation The measurement of performance during an airplane's flight, testing is one of the more important tasks to be accomplished during its development as it impacts on both the airplane's safety and its marketability. This book discusses performance for both propeller-driven and jet aircraft.

This new book is an in-depth study covering John K. "Jack" Northrop\s quest for a clean flying machine. Covered are: Northrop\s initial N-1M project, the N-9M, XP-56, through the B-35 project, B-49 project, and the huge bombers planned only on the drawing board.\nIncluded are over 300 black and white and color photographs, as well as drawings and statistical data on all of the Northrop flying wing and tailless aircraft.

A study of the British manufacturer’s efforts to get its Hunter aircraft into service following World War II. On September 2 1947, Hawker Aircraft Ltd figuratively and literally took to the air with their first jet design, the P.1040. Conceived in the latter days of the Second World War, and developed in the straitened times of post-war austerity, the aircraft allowed Hawker to explore the new technology before moving on to more ambitious programs. Rejected by the Royal Air Force, subsequent development of the aircraft allowed the Royal Navy to find in it a useful role at sea. As this project slowly wound its way through the government bureaucracy against a background of national insolvency, Hawker continued their research into more potent forms of jet travel with their first swept wing aircraft, the P.1052, their first rocket powered example, the P.1072, and, finally, the sleek, all swept P.1081. These essentially research aircraft gave the company the experience and expertise it required to produce a powerful, transonic fighter with which to equip the RAF for the defense of the UK and other friendly nations at a time when the Cold War threatened to engulf the world in a truly global nuclear conflict. That aircraft, the P.1067 Hunter first flew in 1951 and was, at the time, the fastest fighter in the world as evinced by gaining the World Airspeed Record in 1953 prior to entry into RAF service; at a stroke revolutionizing the potential of the UK’s air arm. Such was the haste with which this occurred that many teething problems remained to be resolved, as detailed here, but eventually the aircraft would become the day fighter of choice for many of the world’s air forces and remain in service for decades to come.

The renowned WWII RAF fighter pilot who went on to set an air speed record tells his story—now with an updated chapter and new photos. Joining the RAF at the beginning of the war, young Neville Duke became a fighter pilot with the crack 92 Squadron at RAF Biggin Hill in 1941. That spring and summer, he survived the air battles over Northern France with the Biggin Hill Wing, often flying as wingman to the legendary Adolph “Sailor” Malan, Fighter Command’s top-scoring pilot at that time. Duke quickly established himself as one of the most successful pilots in North Africa, bringing his score to twenty-one by the end of the Tunisian Campaign, and then took command of 145 Spitfire Squadron in Italy. Leading this unit in the summer of 1944, he brought his score to twenty-eight. Earning numerous honors, he was recognized for his heroism, but the military was only the beginning of his life in aviation. Toward the end of the war, he became an RAF test pilot—and later a member of the RAF High Speed Flight. He would go on to a successful postwar career, playing a key role in the flight development on one of the most famous of all RAF peacetime aircraft—the Hawker Hunter—and taking the world speed record in 1953. An in-depth look at his daring exploits covering both his combat career and his postwar accomplishments, Test Pilot is now updated with an additional chapter, appendices and index, and a completely new selection of photographs.
