Raduga Kh-22
The Kh-22 "Storm" (, NATO reporting name AS-4 'Kitchen') is a large, long-range anti-ship cruise missile developed by MKB Raduga in the Soviet Union. It was designed for use against aircraft carriers and carrier battle groups, with either a conventional or nuclear warhead. Kh-32 is an updated conventional variant of the Kh-22 and was accepted to service in 2016; it features an improved rocket motor and a new seeker head. Development After analyzing World War II naval battles and encounters in the late 1940s and early 1950s, Soviet military thinkers concluded that the era of large seaborne battles was over, and that stand-off attacks would be the way to neutralize and incapacitate large battle groups without having to field a similar force against them. Substituting cruise missiles for air attacks, Soviet Air Forces and Soviet Naval Aviation commanders set about converting their heavy bombers to ''raketonosets'', or missile carriers, which could be launched against approa ...

NATO Reporting Name
NATO uses a system of code names, called reporting names, to denote military aircraft and other equipment used by post-Soviet states, former Warsaw Pact countries, China, and other countries. The system assists military communications by providing short, one- or two-syllable names, as alternatives to the precise proper names, which may be easily confused under operational conditions or are unknown in the Western world. The assignment of reporting names is managed by the Five Eyes Air Force Interoperability Council (AFIC), previously known as the Air Standardization Coordinating Committee (ASCC), which is separate from NATO. Based in Washington DC, AFIC comprises representatives from the militaries of three NATO members (Canada, the United Kingdom and United States) and two non-NATO countries (Australia and New Zealand). When the system was introduced in the 1950s, reporting names also implicitly designated potentially hostile aircraft. However, since the end of the Cold War, ...

Kh-32
Kh-32 () is a Russian supersonic air-launched cruise missile with a range of 600–1000 km developed by the MKB Raduga from the Kh-22. The missile was accepted to service in 2016 as armament for the Tu-22M3M bombers. History Work on the modernization of the Kh-22 missile began in the Soviet Union during the late 1980s, due to vulnerability to ECM of its guidance radar Radar is a system that uses radio waves to determine the distance ('' ranging''), direction ( azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method used to detect and track ... operating at fixed frequencies. When an enemy is using radar jamming, the Kh-22 has very low probability of success. A state contract (No. 01133) for development work on an update was signed on 19 June 1990. Due to the general crisis in the country and insufficient financing, work was suspended several times. In 1998, the first missile tests were carried ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shaped Charge
A shaped charge, commonly also hollow charge if shaped with a cavity, is an explosive charge shaped to focus the effect of the explosive's energy. Different types of shaped charges are used for various purposes such as cutting and forming metal, initiating nuclear weapons, penetrating armor, or perforating wells in the oil and gas industry. A typical modern shaped charge, with a metal liner on the charge cavity, can penetrate armor steel to a depth of seven or more times the diameter of the charge (charge diameters, CD), though depths of 10 CD and above have been achieved. Contrary to a misconception, possibly resulting from the acronym ''HEAT'' (high-explosive anti-tank), the shaped charge does not depend in any way on heating or melting for its effectiveness; that is, the jet from a shaped charge does not melt its way through armor, as its effect is purely kinetic in nature—however the process creates significant heat and often has a significant secondary incendiary ef ...

Radio Altimeter
A radar altimeter (RA), also called a radio altimeter (RALT), electronic altimeter, reflection altimeter, or low-range radio altimeter (LRRA), measures altitude above the terrain presently beneath an aircraft or spacecraft by timing how long it takes a beam of radio waves to travel to ground, reflect, and return to the craft. This type of altimeter provides the distance between the antenna and the ground directly below it, in contrast to a barometric altimeter which provides the distance above a defined vertical datum, usually mean sea level. Principle As the name implies, radar (radio detection and ranging) is the underpinning principle of the system. The system transmits radio waves down to the ground and measures the time it takes them to be reflected back up to the aircraft. The altitude above the ground is calculated from the radio waves' travel time and the speed of light. Radar altimeters required a simple system for measuring the time-of-flight that could be displayed u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Mach Number
The Mach number (M or Ma), often only Mach, (; ) is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound. It is named after the Austrian physicist and philosopher Ernst Mach. \mathrm = \frac, where: * is the local Mach number, * is the local flow velocity with respect to the boundaries (either internal, such as an object immersed in the flow, or external, like a channel), and * is the speed of sound in the medium, which in air varies with the square root of the thermodynamic temperature. By definition, at Mach1, the local flow velocity is equal to the speed of sound. At Mach0.65, is 65% of the speed of sound (subsonic), and, at Mach1.35, is 35% faster than the speed of sound (supersonic). The local speed of sound, and hence the Mach number, depends on the temperature of the surrounding gas. The Mach number is primarily used to determine the approximation with which a flow can be treated as an i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Fuming Nitric Acid
Red fuming nitric acid (RFNA) is a storable oxidizer used as a rocket propellant. It consists of nitric acid (), dinitrogen tetroxide () and a small amount of water. The color of red fuming nitric acid is due to the dinitrogen tetroxide, which breaks down partially to form nitrogen dioxide. The nitrogen dioxide dissolves until the liquid is saturated, and produces toxic fumes with a suffocating odor. RFNA increases the flammability of combustible materials and is highly exothermic when reacting with water. Since nitrogen dioxide is a product of decomposition of nitric acid, its addition stabilizes nitric acid in accordance with Le Chatelier's principle. Addition of dinitrogen tetroxide also increases oxidizing power and lowers the freezing point. It is usually used with an inhibitor (with various, sometimes secret, substances, including hydrogen fluoride; any such combination is called ''inhibited RFNA'', ''IRFNA'') because nitric acid attacks most container materials. Hydrogen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tonka-250
Tonka is the name given to a family of German-designed rocket propellants first used under the name R-Stoff in the Wasserfall missile. Tonka propellants were later used in the Soviet Union, most commonly the TG-02 formulation, for example in the engine designs of the A.M. Isayev Chemical Engineering Design Bureau. Their use was later passed on along with other Soviet rocket technology to the Iraq, Iran, Afghanistan and later North Korea. Its name is a reference to the tonka bean. Being invented during the Second World War, it has no connection to the similarly named toys. The original R-Stoff formulation used by Nazi Germany was composed of 43% triethylamine and 57% xylidine. Its most common formulation, known as TONKA-250, TG-02 and under the code name Samin was made of 50% triethylamine and 50% xylidine, most commonly used with nitric acid or its anhydrous nitric oxide derivatives (classified as the AK-2x family in the Soviet Union) as the oxidiser; the combination is hype ...

Rocket Engine
A rocket engine is a reaction engine, producing thrust in accordance with Newton's third law by ejecting reaction mass rearward, usually a high-speed Jet (fluid), jet of high-temperature gas produced by the combustion of rocket propellants stored inside the rocket. However, non-combusting forms such as cold gas thrusters and nuclear thermal rockets also exist. Rocket vehicles carry their own oxidiser, unlike most combustion engines, so rocket engines can be used in a vacuum, and they can achieve great speed, beyond escape velocity. Vehicles commonly propelled by rocket engines include missiles, Rocket-assisted projectile, artillery shells, ballistic missiles and rockets of any size, from tiny Rocket (firework), fireworks to Rocket (weapon), man-sized weapons to huge Space vehicle, spaceships. Compared to other types of jet engine, rocket engines are the lightest and have the highest thrust, but are the least propellant-efficient (they have the lowest specific impulse). The ideal ...

Tupolev Tu-22
The Tupolev Tu-22 ( Air Standardization Coordinating Committee name: Blinder) was the first supersonic bomber to enter production in the Soviet Union. Manufactured by Tupolev, the Tu-22 entered service with Long-Range Aviation and Soviet Naval Aviation in the 1960s. The aircraft was a disappointment, lacking both the speed and range that had been expected. It was also a difficult design to fly and maintain. It was produced in small numbers, especially compared to the Tupolev Tu-16 it was designed to replace. The aircraft was later adapted for other roles, notably as the Tu-22R reconnaissance aircraft and as a carrier for the long-range Kh-22 antiship missile. Tu-22s were sold to other nations, including Libya and Iraq: Libyan Tu-22s were used against Tanzania and Chad, and Iraqi Tu-22s were used during the Iran–Iraq War. Development Previous efforts Andrei Tupolev's OKB-156 had successfully converted the Boeing B-29 Superfortress into the Tupolev Tu-4, while their ...

AV-MF
Soviet Naval Aviation (AV-MF, ) was the naval aviation arm of the Soviet Navy. Origins The first naval aviation units in Russia were formed in 1912–1914 as a part of the Baltic Fleet and the Black Sea Fleet. During World War I, the hydroplane units were used in the Black Sea for conducting aircraft reconnaissance, bombing and firing at coastal and port installations and enemy ships, and destroying submarines and enemy aircraft on the airfields. Civil War and Interwar Period The regular Soviet naval aviation units were created in 1918. They participated in the Russian Civil War, cooperating with the ships and the army during the combats at Petrograd, on the Baltic Sea, the Black Sea, the Volga, the Kama River, Northern Dvina and on the Lake Onega. The newborn Soviet Naval Air Force consisted of only 76 obsolete hydroplanes. Scanty and technically imperfect, it was mostly used for resupplying the ships and the army. In the second half of the 1920s, the Naval Aviation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soviet Air Forces
The Soviet Air Forces (, VVS SSSR; literally "Military Air Forces of the Union of Soviet Socialist Republics"; initialism VVS, sometimes referred to as the "Red Air Force") were one of the air forces of the Soviet Union. The other was the Soviet Air Defence Forces. The Air Forces were formed from components of the Imperial Russian Air Service in 1917, and faced their greatest test during World War II. The groups were also involved in the Korean War, and dissolved along with the Soviet Union itself in 1991–92. Former Soviet Air Forces' assets were subsequently divided into several air forces of former Republics of the Soviet Union, Soviet republics, including the new Russian Air Force. The "Air March, March of the Pilots" was its marching song. Origins The first military aviation branch of Russia or any of the Soviet Union's constituent states was the short-lived Imperial Russian Air Service, founded in 1912 and disbanded in 1917 with the onset of the Bolshevik Revolution and ...
