Hughes D-2
The Hughes D-2 was an American fighter and bomber project begun by Howard Hughes as a private venture. It never proceeded past the flight testing phase but was the predecessor of the Hughes XF-11. The sole D-2 was completed in 1942–1943. Design and development In 1937, Howard Hughes began the design of an advanced twin-engine, twin-boom aircraft. The D-2's early gestation is historically obscure because Hughes Aircraft and its corporate successors have never released archives regarding the D-2; however, Howard Hughes had recently set a global circumnavigation speed record in a Lockheed 14. Aircraft historian René Francillon speculates that Hughes probably initiated the project for another circumnavigation record attempt, but the outbreak of World War II closed much of the world's airspace and made it difficult to buy aircraft parts without government approval, so he decided to sell the aircraft to the U.S. military instead. The first documentary evidence of the project is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fighter Aircraft
Fighter aircraft are fixed-wing military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air superiority of the battlespace. Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical and strategic bombing of enemy targets. The key performance features of a fighter include not only its firepower but also its high speed and maneuverability relative to the target aircraft. The success or failure of a combatant's efforts to gain air superiority hinges on several factors including the skill of its pilots, the tactical soundness of its doctrine for deploying its fighters, and the numbers and performance of those fighters. Many modern fighter aircraft also have secondary capabilities such as ground attack and some types, such as fighter-bombers, are designed from the outset for dual roles. Other fighter designs are highly specialized while still filling the ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tricycle Gear
Tricycle gear is a type of aircraft undercarriage, or ''landing gear'', arranged in a tricycle fashion. The tricycle arrangement has a single nose wheel in the front, and two or more main wheels slightly aft of the center of gravity. Tricycle gear aircraft are the easiest for takeoff, landing and taxiing, and consequently the configuration is the most widely used on aircraft.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 524. Aviation Supplies & Academics, 1997. Aviation Publishers Co. Limited, ''From the Ground Up'', page 11 (27th revised edition) History Several early aircraft had primitive tricycle gear, notably very early Antoinette planes and the Curtiss Pushers of the pre-World War I Pioneer Era of aviation. Waldo Waterman's 1929 tailless '' Whatsit'' was one of the first to have a steerable nose wheel. In 1956, Cessna introduced sprung-steel tricycle landing gear on the Cessna 172. Their marketing department described this as "Land-O-Matic" t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northwest African Photographic Reconnaissance Wing
The Northwest African Photographic Reconnaissance Wing (NAPRW) was a composite Allied photographic reconnaissance wing operational in North Africa during World War II in 1943. History NAPRW was a sub-command of the Northwest African Air Forces which itself was a sub-command of the Mediterranean Air Command (MAC). These new Allied air force organizations were created at the Casablanca Conference in January 1943 to promote cooperation between the British Royal Air Force (RAF), the American United States Army Air Force (USAAF), and their respective ground and naval forces in North Africa and the Mediterranean Theater of Operations (MTO). Effective 18 February 1943, the NAPRW and other MAC commands existed until 10 December 1943 when MAC was disbanded and the Mediterranean Allied Air Forces (MAAF), with the Mediterranean Allied Photographic Reconnaissance Wing (MAPRW), were established. Colonel Elliott Roosevelt, the son of United States President Franklin D. Roosevelt, attended ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elliott Roosevelt (general)
Elliott Roosevelt (September 23, 1910 – October 27, 1990) was an American aviation official and wartime officer in the United States Army Air Forces, reaching the rank of brigadier general. He was a son of President Franklin D. Roosevelt and First Lady Eleanor Roosevelt. As a reconnaissance commander, Roosevelt pioneered new techniques in night photography and meteorological data-gathering, but his claims to a distinguished record on combat missions have been largely discounted. After the war ended, he faced an investigation by the United States Congress on charges of corruption, including accusations that he had recommended the purchase of the experimental Hughes XF-11 reconnaissance aircraft ahead of a Lockheed model that was believed to be superior. Ultimately, he was found blameless. Roosevelt published a book about his attendance at several major Allied war conferences and a controversial exposé of his parents' private life. He also wrote 22 mystery novels. His career als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White House
The White House is the official residence and workplace of the president of the United States. It is located at 1600 Pennsylvania Avenue NW in Washington, D.C., and has been the residence of every U.S. president since John Adams in 1800. The term "White House" is often used as a metonym for the president and his advisers. The residence was designed by Irish-born architect James Hoban in the neoclassical style. Hoban modelled the building on Leinster House in Dublin, a building which today houses the Oireachtas, the Irish legislature. Construction took place between 1792 and 1800, using Aquia Creek sandstone painted white. When Thomas Jefferson moved into the house in 1801, he (with architect Benjamin Henry Latrobe) added low colonnades on each wing that concealed stables and storage. In 1814, during the War of 1812, the mansion was set ablaze by British forces in the Burning of Washington, destroying the interior and charring much of the exterior. Reconstruction began ...

Henry "Hap" Arnold
Henry Harley Arnold (June 25, 1886 – January 15, 1950) was an American general officer holding the ranks of General of the Army and later, General of the Air Force. Arnold was an aviation pioneer, Chief of the Air Corps (1938–1941), commanding general of the United States Army Air Forces, the only United States Air Force general to hold five-star rank, and the only officer to hold a five-star rank in two different U.S. military services. Arnold was also the founder of Project RAND, which evolved into one of the world's largest non-profit global policy think tanks, the RAND Corporation, and was one of the founders of Pan American World Airways. Instructed in flying by the Wright Brothers, Arnold was one of the first military pilots worldwide, and one of the first three rated pilots in the history of the United States Air Force.Arnold, Capt. Charles DeF. Chandler, and Lt. Thomas Milling all qualified for the rating on July 5, 1912. Milling received the first certif ...

USAAF
The United States Army Air Forces (USAAF or AAF) was the major land-based aerial warfare service component of the United States Army and ''de facto'' aerial warfare service branch of the United States during and immediately after World War II (1941–1945). It was created on 20 June 1941 as successor to the previous United States Army Air Corps and is the direct predecessor of the United States Air Force, today one of the six armed forces of the United States. The AAF was a component of the United States Army, which on 2 March 1942 was divided functionally by executive order into three autonomous forces: the Army Ground Forces, the United States Army Services of Supply (which in 1943 became the Army Service Forces), and the Army Air Forces. Each of these forces had a commanding general who reported directly to the Army Chief of Staff. The AAF administered all parts of military aviation formerly distributed among the Air Corps, General Headquarters Air Force, and the ground ...

Attack Aircraft
An attack aircraft, strike aircraft, or attack bomber is a tactical military aircraft that has a primary role of carrying out airstrikes with greater precision than bombers, and is prepared to encounter strong low-level air defenses while pressing the attack.Mortensen 1987, pp. 24–25. This class of aircraft is designed mostly for close air support and naval air-to-surface missions, overlapping the tactical bomber mission. Designs dedicated to non-naval roles are often known as ground-attack aircraft.Gunston 2009, p. 73. Fighter aircraft often carry out the attack role, although they would not be considered attack aircraft ''per se'', although fighter-bomber conversions of those same aircraft would be considered part of the class. Strike fighters, which have effectively replaced the fighter-bomber and light bomber concepts, also differ little from the broad concept of an attack aircraft. The dedicated attack aircraft as a separate class existed primarily during and after Wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pratt & Whitney R-2800
The Pratt & Whitney R-2800 Double Wasp is an American twin-row, 18-cylinder, air-cooled radial aircraft engine with a displacement of , and is part of the long-lived Wasp family of engines. The R-2800 saw widespread use in many important American aircraft during and after World War II. During the war years, Pratt & Whitney continued to develop new ideas to upgrade the engine, including water injection for takeoff in cargo and passenger planes and to give emergency power in combat. Design and development First run in 1937, near the time that the larger competing 18-cylinder Wright Duplex-Cyclone's development had been started in May of that year, the displacement R-2800 was first-flown by 1940, one year before the Duplex-Cyclone. The Double Wasp was more powerful than the world's only other modern 18-cylinder engine, the Gnome-Rhône 18L of . The Double Wasp was much smaller in displacement than either of the other 18-cylinder designs, and heat dissipation was a gr ...

Lockheed XP-58 Chain Lightning
The Lockheed XP-58 Chain Lightning was an American long-range fighter developed during World War II. Although derived from the successful P-38 Lightning, the XP-58 was plagued by technical problems with its engines that eventually led to the project's cancellation. Design and development The XP-58 was a Lockheed Aircraft Company funded initiative to develop an improved Lightning as a long-range fighter following the release by the U.S. Army Air Corps of the Lightning for sale to Britain on 20 April 1940. Initially, two designs were formulated, both using the Continental IV-1430 engines. One would be a single-seat aircraft with one 20 mm (.79 in) cannon and four .50 in (12.7 mm) machine guns. The second would be a two-seat aircraft with the addition of a flexible .50 in (12.7 mm) gun at the end of each tail boom.Francillon 1982, p. 252. In July 1940, Lockheed decided to switch to Pratt & Whitney XH-2600 engines as the aircraft would be underpowered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Force Materiel Command
Air Force Materiel Command (AFMC) is a major command (MAJCOM) of the United States Air Force (USAF). AFMC was created on July 1, 1992, through the amalgamation of the former Air Force Logistics Command (AFLC) and the former Air Force Systems Command (AFSC). AFMC is headquartered at Wright-Patterson Air Force Base in Dayton, Ohio. AFMC is one of nine Air Force Major Commands and has a workforce of approximately 80,000 military and civilian personnel. It is the Air Force's largest command in terms of funding and second in terms of personnel. AFMC's operating budget represents 31 percent of the total Air Force budget and AFMC employs more than 40 percent of the Air Force's total civilian workforce. The command conducts research, development, testing and evaluation, and provides the acquisition and life cycle management services and logistics support. The command develops, acquires and sustains the air power needed to defend the United States and its interests. This is accomplished ...
