Gorgon (missile Family)
The Gorgon missile family was a series of experimental air-to-air, air-to-surface, and surface-to-surface missiles developed by the United States Navy's Naval Aircraft Modification Unit between 1943 and 1953. The immaturity of the technology involved meant that none of the Gorgon missiles achieved operational service, however they were extensively used in the development of guided missile controls and guidance technologies. History In the late 1930s, then-Commander Delmer S. Fahrney proposed that an "aerial torpedo" be developed for the purpose of intercepting bomber aircraft; while in 1940 the U.S. Navy Bureau of Aeronautics investigated the concept, it was only in May 1943, with the advent of practical jet and rocket engines, that the United States Navy initiated the Gorgon missile program, headquartered at the Naval Aircraft Modification Unit (later Naval Air Development Station) in Pennsylvania.Parsch 2005 The original design for Gorgon called for a turbojet-powered m ...

Naval Aircraft Modification Unit
Naval Air Warfare Center Warminster was a U.S. Navy military installation located in Warminster, Pennsylvania and Ivyland, Pennsylvania. For most of its existence (1949–1993), the base was known as the Naval Air Development Center (NADC) Warminster, but it has also been referred to as Johnsville Naval Air Development Center, NADC Johnsville or simply, Johnsville. History Early history In 1944, the US Navy took over the lease of the property of the Brewster Aeronautical Corporation following a period of . The Brewster Buccaneer dive bomber was produced by Brewster at this location, which was known as Brewster Field. Following the US Navy takeover, the site was known as the Naval Aircraft Modification Unit (NAMU). It was considered a branch of the Naval Air Material Center (NAMC). It was a modification center for fleet aircraft before they were sent to the fleet. Wing panels for PBYs were manufactured here, and assembled on planes at Mustin Field at the Philadelphia Naval Ai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infrared Homing
Infrared homing is a passive weapon guidance system which uses the infrared (IR) light emission from a target to track and follow it seamlessly. Missiles which use infrared seeking are often referred to as "heat-seekers" since infrared is radiated strongly by hot bodies. Many objects such as people, vehicle engines and aircraft generate and emit heat and so are especially visible in the infrared wavelengths of light compared to objects in the background. Infrared seekers are passive devices, which, unlike radar, provide no indication that they are tracking a target. That makes them suitable for sneak attacks during visual encounters or over longer ranges when they are used with a forward looking infrared or similar cuing system. Heat-seekers are extremely effective: 90% of all United States air combat losses over the past 25 years have been caused by infrared-homing missiles. They are, however, subject to a number of simple countermeasures, most notably by dropping flares beh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CTV-N-2 Gorgon IIC
The CTV-N-2 Gorgon IIC – also designated KGN, KUN, and CTV-2 – was an experimental drone, originally intended as a surface-to-surface missile, developed by the United States Navy near the end of World War II. It was used to test control and homing systems for guided missiles, and was also produced in small numbers as a target drone under the designations TD3N and KD2N. Design and development Late in World War II, the U.S. Navy began development of a pulsejet-powered bombardment missile,Ordway and Wakeford 1960, p.181. intended to be launched from ships for use against targets ashore; in April 1945, plans for the invasion of Japan called for the production of "several hundred" missiles, named Gorgon IIC; initially, 20 prototype missiles were to be produced by the Naval Aircraft Modification Unit in Pennsylvania, while an order for 100 was placed with the Singer Manufacturing Company, a sewing machine manufacturer, in August 1945.White 1991, p.36. The end of the war saw the can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KA2N Gorgon IIA
The KA2N Gorgon IIA – also designated KU2N, CTV-4, and CTV-N-4 – was an air-to-air missile developed by the United States Navy near the end of World War II. Proving a failure in its designed role, it was repurposed as an experimental testbed for missile technology. Design and development The Gorgon missile program began in July 1943 at the Naval Aircraft Modification Unit in Warminster, Pennsylvania, and was intended to develop a family of small air-launched missiles for air-to-air and air-to-surface roles.Parsch 2005 The Gorgon IIA, the baseline design of the family, was of canard configuration, a conventional high-mounted monoplane wing providing lift; the structure was largely of laminated wood, while propulsion was by a Reaction Motors CML2N liquid-fuel rocket, fueled with monoethylamine and nitric acid. Intended for use intercepting bombers or transport aircraft, the Gorgon IIA was said to be the first American guided missile to be powered by a liquid-fueled rocket. It ...

Cold War
The Cold War is a term commonly used to refer to a period of geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc. The term '' cold war'' is used because there was no large-scale fighting directly between the two superpowers, but they each supported major regional conflicts known as proxy wars. The conflict was based around the ideological and geopolitical struggle for global influence by these two superpowers, following their temporary alliance and victory against Nazi Germany and Imperial Japan in 1945. Aside from the nuclear arsenal development and conventional military deployment, the struggle for dominance was expressed via indirect means such as psychological warfare, propaganda campaigns, espionage, far-reaching embargoes, rivalry at sports events, and technological competitions such as the Space Race. The Western Bloc was led by the United States as well as a number of other First W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atomic Bombings Of Hiroshima And Nagasaki
The United States detonated two atomic bombs over the Japanese cities of Hiroshima and Nagasaki on 6 and 9 August 1945, respectively. The two bombings killed between 129,000 and 226,000 people, most of whom were civilians, and remain the only use of nuclear weapons in armed conflict so far. In the final year of World War II, the Allies prepared for a costly invasion of the Japanese mainland. This undertaking was preceded by a conventional and firebombing campaign that devastated 64 Japanese cities. The war in the European theatre concluded when Germany surrendered on 8 May 1945, and the Allies turned their full attention to the Pacific War. By July 1945, the Allies' Manhattan Project had produced two types of atomic bombs: "Fat Man", a plutonium implosion-type nuclear weapon; and "Little Boy", an enriched uranium gun-type fission weapon. The 509th Composite Group of the United States Army Air Forces was trained and equipped with the specialized Silverplate version of the ...

Singer Manufacturing Company
Singer Corporation is an American manufacturer of consumer sewing machines, first established as I. M. Singer & Co. in 1851 by Isaac M. Singer with New York lawyer Edward C. Clark. Best known for its sewing machines, it was renamed Singer Manufacturing Company in 1865, then the Singer Company in 1963. It is based in La Vergne, Tennessee, near Nashville. Its first large factory for mass production was built in 1863 in Elizabeth, New Jersey. History Singer's original design was the first practical sewing machine for general domestic use. It incorporated the basic eye-pointed needle and lock stitch, developed by Elias Howe, who won a patent-infringement suit against Singer in 1854. Singer obtained in August 1851 for an improved sewing machine that included a circular feed wheel, thread controller, and power transmitted by gear wheels and shafting. Singer consolidated enough patents in the field to enable him to engage in mass production, and by 1860 his company was the la ...

Operation Downfall
Operation Downfall was the proposed Allied plan for the invasion of the Japanese home islands near the end of World War II. The planned operation was canceled when Japan surrendered following the atomic bombings of Hiroshima and Nagasaki, the Soviet declaration of war, and the invasion of Manchuria. The operation had two parts: Operation Olympic and Operation Coronet. Set to begin in November 1945, Operation Olympic was intended to capture the southern third of the southernmost main Japanese island, Kyūshū, with the recently captured island of Okinawa to be used as a staging area. In early 1946 would come Operation Coronet, the planned invasion of the Kantō Plain, near Tokyo, on the main Japanese island of Honshu. Airbases on Kyūshū captured in Operation Olympic would allow land-based air support for Operation Coronet. If Downfall had taken place, it would have been the largest amphibious operation in history, surpassing D-Day. Japan's geography made this invasion pl ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molt Taylor
Moulton B. "Molt" Taylor (September 29, 1912 – November 16, 1995) was an American aeronautical engineer famed for his work designing, developing, and manufacturing on a small scale one of the first practical flying cars, the Aerocar. Life and career Taylor was born in Portland, Oregon and studied engineering at the University of Washington. After graduation, he was accepted into the United States Navy as a pilot during World War II, and spent much of the war working on the Navy's Gorgon missile program, for which he was awarded the Legion of Merit medal. Shortly after the war, he designed his first flying car, the Aerocar, and founded Aerocar International in Longview, Washington, to develop, manufacture and market the aircraft. Taylor came up with the idea for the Aerocar in 1946, after meeting inventor Robert Edison Fulton Jr. and noticing the flaws in his Airphibian roadable aircraft design. To date, Taylor's Aerocar remains the closest that any such design came to act ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ramjet
A ramjet, or athodyd (aero thermodynamic duct), is a form of airbreathing jet engine that uses the forward motion of the engine to produce thrust. Since it produces no thrust when stationary (no ram air) ramjet-powered vehicles require an assisted take-off like a rocket assist to accelerate it to a speed where it begins to produce thrust. Ramjets work most efficiently at supersonic speeds around and can operate up to speeds of . Ramjets can be particularly useful in applications requiring a small and simple mechanism for high-speed use, such as missiles. The US, Canada, and UK had widespread ramjet powered missile defenses during the 1960s onward, such as the CIM-10 Bomarc and Bloodhound. Weapon designers are looking to use ramjet technology in artillery shells to give added range; a 120 mm mortar shell, if assisted by a ramjet, is thought to be able to attain a range of . They have also been used successfully, though not efficiently, as tip jets on the ends of helicopt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
