6300-407: The spar to provide variable incidence. For takeoff and landing, the wing was tilted upwards to increase the angle of incidence while keeping the fuselage nearly horizontal. The length of the fuselage made it difficult to achieve the same end by tilting the entire aircraft upwards, which would have required a very long extension on the landing gear . The system also allowed the fuselage to fly flat to

6384-462: The supersonic air to a usable speed. The energy lost in this process heats the air, which means the engine has to operate at ever-higher temperatures to provide net thrust. The limiting factor in this process is the temperature of the materials in the engines, in particular, the turbine blades just behind the combustion chambers. Using materials available at the time, speeds much beyond Mach 2.5 were difficult to achieve. The solution to this problem

6468-501: The three military departments of the Department of Defense . The Air Force through the Department of the Air Force is headed by the civilian Secretary of the Air Force , who reports to the Secretary of Defense and is appointed by the President with Senate confirmation . The highest-ranking military officer in the Air Force is the Chief of Staff of the Air Force , who exercises supervision over Air Force units and serves as one of

6552-467: The war, with only the infantry suffering more casualties. In practice, the U.S. Army Air Forces ( USAAF ) was virtually independent of the Army during World War II, and in virtually every way functioned as an independent service branch, but airmen still pressed for formal independence. The National Security Act of 1947 was signed on 26 July 1947, which established the Department of the Air Force , but it

6636-418: Was common for aircraft of the era. The fuselage was completely smooth, with a high fineness ratio for low drag at supersonic speeds. The design was developed prior to the discovery of the area rule , and does not display any of the wasp waisting common to aircraft primarily developed after 1952. The fuselage contours were mainly cylindrical, but blended into the intake starting around the wing root, giving it

6720-459: Was locked up. The entire nose of the aircraft was taken up by the large Hughes radar set, which (at the time) offered long detection ranges. Guidance and fire control were to be provided by the same MX-1179 package being developed for all of the WS-201 designs. Hughes had won this contract with their Hughes MA-1 fire control system, which was under development. Weapons were carried in bays located on

6804-500: Was not until 18 September 1947, when the first secretary of the Air Force, W. Stuart Symington , was sworn into office that the Air Force was officially formed as an independent service branch. The act created the National Military Establishment (renamed Department of Defense in 1949), which was composed of three subordinate Military Departments, namely the Department of the Army , the Department of

6888-624: Was taking place. In 1938, at the age of 26, he received Italy's highest prize for science, the Premio dell'Accademia d'Italia for science. Among the work he conducted there were spectacular experiments in 1939–1940 with supersonic wind tunnels . During World War II , in the period of the Italian Social Republic (or Salò Republic), three days after the Germans occupied Rome on 10 September 1943, Ferri bluffed his way back into

6972-429: Was that he had repeatedly clashed with Wynne and Moseley over other important non-nuclear related issues to the service. This followed an investigation into two incidents involving mishandling of nuclear weapons : specifically a nuclear weapons incident aboard a B-52 flight between Minot AFB and Barksdale AFB , and an accidental shipment of nuclear weapons components to Taiwan. To put more emphasis on nuclear assets,

7056-530: Was the first officer appointed to that position who did not have a background as a fighter or bomber pilot. The Washington Post reported in 2010 that General Schwartz began to dismantle the rigid class system of the USAF, particularly in the officer corps. In 2014, following morale and testing/cheating scandals in the Air Force's missile launch officer community, Secretary of the Air Force Deborah Lee James admitted that there remained
