Cruise Missile
A cruise missile is an unmanned self-propelled guided missile that sustains flight through aerodynamic lift for most of its flight path. Cruise missiles are designed to deliver a large payload over long distances with high precision. Modern cruise missiles are capable of traveling at high Aerodynamics#Incompressible aerodynamics, subsonic, Supersonic speed, supersonic, or Hypersonic speed, hypersonic speeds, are self-navigating, and are able to fly on a non-Ballistics, ballistic, extremely low-altitude trajectory. History The idea of an "aerial torpedo" was shown in the British 1909 film ''The Airship Destroyer'' in which flying torpedoes controlled wirelessly are used to bring down airships bombing London. In 1916, the Americans, American Aircraft pilot, aviator Lawrence Sperry built and patented an "aerial torpedo", the Hewitt-Sperry Automatic Airplane, a small biplane carrying a TNT charge, a Sperry autopilot and barometric altitude control. Inspired by the experiments, the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Tomahawk Block IV Cruise Missile -crop
A tomahawk is a type of single-handed axe used by the many Native Americans in the United States, Indian peoples and nations of North America, traditionally resembles a hatchet with a straight shaft. Etymology The name comes from Powhatan language, Powhatan , derived from the Proto-Algonquian root 'to cut off by tool'. Algonquian languages, Algonquian cognates include Lenape language, Lenape , Malecite-Passamaquoddy language, Malecite-Passamaquoddy , and Abenaki language, Abenaki , all of which mean 'axe'. The term came into the English language in the 17th century as an Anglicisation#Anglicisation of loanwords, adaptation of the Powhatan (Virginian Eastern Algonquian languages, Algonquian) word. History The Algonquian people created the tomahawk. Before Europeans came to the continent, Native Americans would use stones, sharpened by a process of knapping and pecking, attached to wooden handles, secured with strips of Rawhide (material), rawhide. The tomahawk quickly spread ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Siemens-Schuckert
Siemens-Schuckert (or Siemens-Schuckertwerke) was a German electrical engineering company headquartered in Berlin, Erlangen and Nuremberg that was incorporated into the Siemens AG in 1966. Siemens Schuckert was founded in 1903 when Siemens & Halske acquired Schuckertwerke. Subsequently, Siemens & Halske specialized in communications engineering and Siemens-Schuckert in power engineering and pneumatic instrumentation. During World War I Siemens-Schuckert also produced aircraft. It took over manufacturing of the Protos vehicles in 1908. In World War II, the company had a factory producing aircraft and other parts at Monowitz near Auschwitz. There was a workers camp near the factory known as Bobrek concentration camp. The Siemens Schuckert logo consisted of an S with a smaller S superimposed on the middle with the smaller S rotated left by 45 degrees.Siemens used this as a theme for their logos with absorbed companies: Siemens & Halske's logo was a large S with a small superimp ...

Ballistic Missile
A ballistic missile is a type of missile that uses projectile motion to deliver warheads on a target. These weapons are powered only during relatively brief periods—most of the flight is unpowered. Short-range ballistic missiles (SRBM) typically stay within the Earth's atmosphere, while most larger missiles travel outside the atmosphere. The type of ballistic missile with the greatest range is an intercontinental ballistic missile (ICBM). The largest ICBMs are capable of full orbital flight. These missiles are in a distinct category from cruise missiles, which are aerodynamically guided in powered flight and thus restricted to the atmosphere. History One modern pioneer ballistic missile was the A-4, commonly known as the V-2, developed by Nazi Germany in the 1930s and 1940s under the direction of Wernher von Braun. The first successful launch of a V-2 was on October 3, 1942, and it began operation on September 6, 1944, against Paris, followed by an attack on London two ...

V-2 Rocket
The V2 (), with the technical name ''Aggregat (rocket family), Aggregat-4'' (A4), was the world's first long-range missile guidance, guided ballistic missile. The missile, powered by a liquid-propellant rocket engine, was developed during the Second World War in Nazi Germany as a "V-weapons, vengeance weapon" and assigned to attack Allies of World War II, Allied cities as retaliation for the Strategic bombing during World War II#The British later in the war, Allied bombings of German cities. The rocket also became the first artificial object to travel into space by crossing the Kármán line (edge of space) with the vertical launch of MW 18014 on 20 June 1944. Research of military use of long-range rockets began when the graduate studies of Wernher von Braun were noticed by the German Army. A series of prototypes culminated in the A4, which went to war as the . Beginning in September 1944, more than 3,000 were launched by the Wehrmacht against Allied targets, first London and ...

Pulsejet
file:Pulse Jet Engine.PNG, 300px, Diagram of a valved pulsejet. 1 - Air enters through valve and is mixed with fuel. 2 - The mixture is ignited, expands, closes the valve and exits through the tailpipe, creating thrust.3 - Low pressure in the engine opens the valve and draws in air. A pulsejet engine (or pulse jet) is a type of jet engine in which combustion occurs in Pulse (physics), pulses. A pulsejet engine can be made with few or no moving parts, and is capable of running statically (that is, it does not need to have air forced into its inlet, typically by forward motion). The best known example is the Argus As 109-014 used to propel Nazi Germany's V-1 flying bomb. Pulsejet engines are a lightweight form of jet propulsion, but usually have a poor compression ratio, and hence give a low specific impulse. The two main types of pulsejet engines use resonant combustion and harness the combustion products to form a pulsating exhaust jet that intermittently produces thrust. T ...

V-1 Flying Bomb
The V-1 flying bomb ( "Vengeance Weapon 1") was an early cruise missile. Its official Reich Aviation Ministry () name was Fieseler Fi 103 and its suggestive name was (hellhound). It was also known to the Allies as the buzz bomb or doodlebug and (maybug). The V-1 was the first of the (V-weapons) deployed for the terror bombing of London. It was developed at Peenemünde Army Research Center in 1939 by the at the beginning of the Second World War, and during initial development was known by the codename "Cherry Stone". Due to its limited range, the thousands of V-1 missiles launched into England were fired from V-1 flying bomb facilities, launch sites along the French (Pas-de-Calais) and Dutch coasts or by modified Heinkel He 111 aircraft. The Wehrmacht first launched the V-1s against London on 13 June 1944, one week after (and prompted by) Operation Overlord, the Allied landings in France. At times more than one hundred V-1s a day were fired at south-east England, 9,521 in t ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

World War II
World War II or the Second World War (1 September 1939 – 2 September 1945) was a World war, global conflict between two coalitions: the Allies of World War II, Allies and the Axis powers. World War II by country, Nearly all of the world's countries participated, with many nations mobilising all resources in pursuit of total war. Tanks in World War II, Tanks and Air warfare of World War II, aircraft played major roles, enabling the strategic bombing of cities and delivery of the Atomic bombings of Hiroshima and Nagasaki, first and only nuclear weapons ever used in war. World War II is the List of wars by death toll, deadliest conflict in history, causing World War II casualties, the death of 70 to 85 million people, more than half of whom were civilians. Millions died in genocides, including the Holocaust, and by massacres, starvation, and disease.

Gyroscope
A gyroscope (from Ancient Greek γῦρος ''gŷros'', "round" and σκοπέω ''skopéō'', "to look") is a device used for measuring or maintaining Orientation (geometry), orientation and angular velocity. It is a spinning wheel or disc in which the axis of rotation (spin axis) is free to assume any orientation by itself. When rotating, the orientation of this axis is unaffected by tilting or rotation of the mounting, due to the angular momentum#Conservation of angular momentum, conservation of angular momentum. Gyroscopes based on other operating principles also exist, such as the microchip-packaged Vibrating structure gyroscope#MEMS gyroscopes, MEMS gyroscopes found in electronic devices (sometimes called gyrometers), solid-state ring laser gyroscope, ring lasers, fibre optic gyroscopes, and the extremely sensitive quantum gyroscope. Applications of gyroscopes include inertial navigation systems, such as in the Hubble Space Telescope, or inside the steel hull of a submer ...

Glide Bomb
A glide bomb or stand-off bomb is a standoff weapon with flight control surfaces to give it a flatter, gliding flight path than that of a conventional bomb without such surfaces. This allows it to be released at a distance from the target rather than right over it, allowing a successful attack without exposing the launching aircraft to anti-aircraft defenses near the target. Glide bombs can accurately deliver warheads in a manner comparable to cruise missiles at a fraction of the cost—sometimes by installing flight control kits on simple unguided bombs—and they are very difficult for surface-to-air missiles to intercept due to their tiny radar signatures and short flight times. The only effective countermeasure in most cases is to shoot down enemy aircraft before they approach within launching range, making glide bombs very potent weapons where wartime exigencies prevent this. World War II-era glide bombs like the German Fritz X and Henschel Hs 293 pioneered the use o ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Group For The Study Of Reactive Motion
The Moscow-based Group for the Study of Reactive Motion (also known as the ''Group for the Investigation of Reactive Engines and Reactive Flight'' or ''Jet Propulsion Study Group''; ), abbreviated as GIRD (), was a Soviet research bureau founded in 1931 to study various aspects of rocketry. GIRD launched the first Soviet Liquid-propellant rocket, liquid propellant rocket in August 1933. In November 1933 it was incorporated into the Reactive Scientific Research Institute (, , РНИИ, RNII). History The inspiration for establishing the organisation came from Friedrich Zander, Fredrich Tsander, a scientist, inventor, and romantic who dreamed of space travel. Tsander had begun to consider rocket-powered interplanetary flight as early as 1907 and was one of the founding members of the Society for the Study of Interplanetary Communication in 1924. In September 1931 Tsander formed the Moscow-based 'Group for the Study of Reactive Motion', better known by its Russian acronym “GIRD” ...

Sergei Korolev
Sergei Pavlovich Korolev (14 January 1966) was the lead Soviet Aerospace engineering, rocket engineer and spacecraft designer during the Space Race between the United States and the Soviet Union in the 1950s and 1960s. He invented the R-7 Semyorka, R-7 Rocket, Sputnik 1, and was involved in the launching of Laika, Sputnik 3, the first luna 2, human-made object to make contact with another celestial body, Soviet space dogs#Belka and Strelka, Belka and Strelka, the first human being, Yuri Gagarin, into space, Voskhod 1, and the first person, Alexei Leonov, to conduct a Voskhod 2, spacewalk. Although Korolev trained as an aircraft designer, his greatest strengths proved to be in design integration, organization and strategic planning. Arrested on a false official charge as a "member of an anti-Soviet counter-revolutionary organization" (which would later be reduced to "saboteur of military technology"), he was imprisoned in 1938 for almost six years, including a few months in a K ...
