Hughes XH-17
The Hughes XH-17 "Flying Crane" was the first helicopter project for the helicopter division of Hughes Aircraft Company. The XH-17, which had a two-bladed main rotor system with a diameter of 134 feet (41 m), still holds the world record for flying with the largest rotor system. It was capable of flying at a gross weight of more than , but proved too inefficient and cumbersome to be mass-produced beyond the prototype unit. Design and development The XH-17 was a heavy-lift rotorcraft that was designed to lift loads in excess of 15 metric tons. To speed construction, parts of the XH-17 were scavenged from other aircraft. The front wheels came from a North American B-25 Mitchell and the rear wheels from a Douglas C-54 Skymaster. The fuel tank was a bomb bay-mounted unit from a Boeing B-29 Superfortress. The cockpit was from a Waco CG-15 military glider and the tail rotor from a Sikorsky H-19 Chickasaw was used for yaw control. In the late 1940s, Hughes developed an interest in h ...

Four Digit Groups Of The United States Air Force
4 (four) is a number, numeral and digit. It is the natural number following 3 and preceding 5. It is the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures. In mathematics Four is the smallest composite number, its proper divisors being and . Four is the sum and product of two with itself: 2 + 2 = 4 = 2 x 2, the only number b such that a + a = b = a x a, which also makes four the smallest squared prime number p^. In Knuth's up-arrow notation, , and so forth, for any number of up arrows. By consequence, four is the only square one more than a prime number, specifically three. The sum of the first four prime numbers two + three + five + seven is the only sum of four consecutive prime numbers that yields an odd prime number, seventeen, which is the fourth super-prime. Four lies between the first proper pair of twin primes, three and five, which are the first two Fermat primes, like seventeen, which is the third. On the other h ...

3200th Drone Squadron
The 3205th Drone Squadron is a discontinued United States Air Force unit. It was last active with the Air Proving Ground Center based at Eglin Air Force Base, Florida, where it was discontinued on 25 October 1963. The squadron operated various drones between 1950 and 1963 to provide targets to support development of weapons and for interceptor training. History The 3205th Drone Squadron was organized in April 1950, when it assumed the mission of operating QB-17L Flying Fortresses as drone aerial targets from the 550th Guided Missiles Wing. The squadron operated QB-17 drones and DB-17 controller aircraft, providing aerial targets for surface-to-air and air-to-air missile development programs at Eglin Air Force Base, Florida. The unit also used QF-80 Shooting Star jets for aerial gunnery targets for Air Defense Command interceptor squadrons.

3206th Test Group
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious or cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th ...

B-47 Stratojet
The Boeing B-47 Stratojet (Boeing company designation Model 450) is a retired American long-range, six-engined, turbojet-powered strategic bomber designed to fly at high subsonic speed and at high altitude to avoid enemy interceptor aircraft. The primary mission of the B-47 was as a nuclear bomber capable of striking targets within the Soviet Union. Development of the B-47 can be traced back to a requirement expressed by the United States Army Air Forces (USAAF) in 1943 for a reconnaissance bomber that harnessed newly developed jet propulsion. Another key innovation adopted during the development process was the swept wing, drawing upon captured German research. With its engines carried in nacelles underneath the wing, the B-47 represented a major innovation in post- World War II combat jet design, and contributed to the development of modern jet airliners. Suitably impressed, in April 1946, the USAAF ordered two prototypes, designated "XB-47"; on 17 December 1947, the fir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TM-61 Madador
The Martin MGM-1 Matador was the first operational surface-to-surface cruise missile designed and built by the United States. It was developed after World War II, drawing upon their wartime experience with creating the Republic-Ford JB-2, a copy of the German V-1. The Matador was similar in concept to the V-1, but it included a radio command that allowed in-flight course corrections. This allowed accuracy to be maintained over greatly extended ranges of just under 1000 km. To allow these ranges, the Matador was powered by a small turbojet engine in place of the V-1's much less efficient pulsejet. Matador was armed with the W5 nuclear warhead, essentially an improved version of the Fat Man design that was lighter and had a smaller cross section. A single U.S. Air Force group, 1st Pilotless Bomber Squadron, was armed with the weapon, keeping them on alert with a six-minute launch time. It could be easily retargeted, unlike weapons using inertial guidance systems. Acc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
F-82B Twin Mustang
The North American F-82 Twin Mustang is the last American piston-engined fighter ordered into production by the United States Air Force. Based on the North American P-51 Mustang, the F-82 was originally designed as a long-range escort fighter for the Boeing B-29 Superfortress in World War II. The war ended well before the first production units were operational. In the postwar era, Strategic Air Command used the aircraft as a long-range escort fighter. Radar-equipped F-82s were used extensively by the Air Defense Command as replacements for the Northrop P-61 Black Widow as all-weather day/night interceptors. During the Korean War, Japan-based F-82s were among the first USAF aircraft to operate over Korea. The first three North Korean aircraft destroyed by U.S. forces were shot down by F-82s, the first being a North-Korean Yakovlev Yak-11, Yak-11 downed over Gimpo International Airport, Gimpo Airfield by the USAF 68th Fighter Squadron.

Wagner Field
Wagner Field, (Formerly: Eglin Air Force Auxiliary Field #1), is a component of Eglin Air Force Base, Florida. It is located northeast of the main base, 13.9 miles northeast of Valparaiso, Florida. The site is notable as the training location for the Doolittle Raiders in early 1942, and the test location for the Credible Sport YMC-130H STOL 1980 Iranian Hostage rescue attempt aircraft. History With the onset of World War II, the Eglin Field military reservation was greatly expanded when the Choctawhatchee National Forest was turned over to the War Department by the U.S. Forestry Service on 18 October 1940, and a series of auxiliary airfields were constructed from January 1941. Work on Auxiliary Field 1, consisting of a triangular set of runways, began 27 November 1940. $800,000 was allocated for the grading and paving of fields 1, 3, 5, and 6 on 24 April 1941. Auxiliary Field 1 was subsequently named Wagner Field for Major Walter J. Wagner, USAAF, former commanding officer f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
B-36 Peacemaker
The Convair B-36 "Peacemaker" is a strategic bomber that was built by Convair and operated by the United States Air Force (USAF) from 1949 to 1959. The B-36 is the largest mass-produced piston-engined aircraft ever built. It had the longest wingspan of any combat aircraft ever built, at . The B-36 was the first bomber capable of delivering any of the nuclear weapons in the U.S. arsenal from inside its four bomb bays without aircraft modifications. With a range of and a maximum payload of , the B-36 was capable of intercontinental flight without refuelling. Entering service in 1948, the B-36 was the primary nuclear weapons delivery vehicle of Strategic Air Command (SAC) until it was replaced by the jet-powered Boeing B-52 Stratofortress beginning in 1955. All but four aircraft have been scrapped. Development The genesis of the B-36 can be traced to early 1941, prior to the entry of the United States into World War II. At the time, the threat existed that Britain might fall to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
