Musudan
The Hwasong-10 (), also known by the names BM-25 and Musudan (), is a mobile intermediate-range ballistic missile developed by North Korea. Hwasong-10 was first revealed to the international community in a military parade on 10 October 2010 celebrating the Workers' Party of Korea's 65th anniversary, although experts believe these were mock-ups of the missile. Hwasong-10 resembles the shape of the Soviet Union's R-27 Zyb submarine-launched missile, but is slightly longer. It is based on the R-27, which uses a 4D10 engine propelled by unsymmetrical dimethylhydrazine (UDMH) and nitrogen tetroxide (NTO). These propellants are much more advanced than the kerosene compounds used in North Korea's Scuds and Nodong missiles. Since April 2016 the Hwasong-10 has been tested a number of times, with two apparent partial successes and a number of failures. The Hwasong-10 was not shown in the April 2017 and February 2018 military parades, suggesting that the design had not been deployed. Assu ...

R-27 Zyb
The R-27 Zyb was a submarine-launched ballistic missile developed by the Soviet Union and employed by the Soviet Navy from 1968 through 1988. NATO assigned the missile the reporting name SS-N-6 Serb. In the USSR, it was given the GRAU index 4K10. It was a liquid fuel rocket using a hypergolic combination of unsymmetrical dimethylhydrazine (UDMH) as fuel, and nitrogen tetroxide (NTO) as oxidizer. Between 1974 and 1990, 161 missile launches were conducted, with an average success rate of 93%. Total production was 1800 missiles. The R-27 missiles were deployed on the Yankee I submarines, including the K-219. Technical details The missile's body is an all-welded construction made of hard-worked AMg6 (АМг6) aluminium-magnesium-alloy panels, which underwent a two-step process of deep industrial etching and mechanical milling, reducing the plate thickness to one-fifth and one-ninth of the thickness of the original plate. The outer surface of the missile was covered with an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scud
A Scud missile is one of a series of tactical ballistic missiles developed by the Soviet Union during the Cold War. It was exported widely to both Second World, Second and Third World, Third World countries. The term comes from the NATO reporting name attached to the missile by Western intelligence agencies. The Russian names for the missile are the R-11 (the first version), and the R-17 (later R-300) Elbrus (later developments). The name Scud has been widely used to refer to these missiles and the wide variety of derivative variants developed in other countries based on the Soviet design. Scud missiles have been used in combat since the 1970s, mostly in wars in the Middle East. They became familiar to the Western public during the 1991 Persian Gulf War, when Ba'athist Iraq, Iraq fired dozens at Israel and Saudi Arabia. In Russian service it is being replaced by the 9K720 Iskander. Development The first use of the term ''Scud'' was in the NATO name SS-1b Scud-A, applied to the ...

Intermediate-range Ballistic Missile
An intermediate-range ballistic missile (IRBM) is a ballistic missile with a range of 3,000–5,500 km (1,864–3,418 miles), between a medium-range ballistic missile (MRBM) and an intercontinental ballistic missile (ICBM). Classifying ballistic missiles by range is done mostly for convenience; in principle there is very little difference between a low-performance ICBM and a high-performance IRBM, because decreasing payload mass can increase range over ICBM threshold. The range definition used here is used within the U.S. Missile Defense Agency. Some other sources include an additional category, the long-range ballistic missile (LRBM), to describe missiles with a range between IRBMs and true ICBMs. The more modern term theatre ballistic missile encompasses MRBMs and SRBMs, including any ballistic missile with a range under . The progenitor for the IRBM was the A4b winged rocket, based on the V-2 (officially called A4) rocket used by Nazi Germany at the end of World War II ...

Liquid-propellant Rocket
A liquid-propellant rocket or liquid rocket utilizes a rocket engine that uses liquid rocket propellant, liquid propellants. Liquids are desirable because they have a reasonably high density and high Specific impulse, specific impulse (''I''sp). This allows the volume of the propellant tanks to be relatively low. It is also possible to use lightweight centrifugal turbopumps to pump the rocket propellant from the tanks into the combustion chamber, which means that the propellants can be kept under low pressure. This permits the use of low-mass propellant tanks that do not need to resist the high pressures needed to store significant amounts of gasses, resulting in a low mass ratio for the rocket. An inert gas stored in a tank at a high pressure is sometimes used instead of pumps in simpler small engines to force the propellants into the combustion chamber. These engines may have a higher mass ratio, but are usually more reliable, and are therefore used widely in satellites for orbit ...

Khorramshahr Missile
Khorramshahr ( fa, خرمشهر , also romanized as ''Khurramshahr'', ar, المحمرة, romanized as ''Al-Muhammerah'') is a city and capital of Khorramshahr County, Khuzestan Province, Iran. At the 2016 census, its population was 170,976, in 47,380 households. Khorramshahr is an inland port city located approximately north of Abadan. The city extends to the right bank of the Shatt Al Arab waterway near its confluence with the Haffar arm of the Karun river. The city was destroyed in the Iran–Iraq War, with the 1986 census recording a population of zero. However, Khorramshahr was rebuilt after the war, and more recent censuses show that the population has returned to its approximate pre-war level. History The area where the city exists today was originally under the waters of the Persian Gulf. It later became part of the vast marshlands and the tidal flats at the mouth of the Karun River. The small town known as ''Piyan'', and later ''Bayan'' appeared in the area no sooner t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lofted Trajectory
Projectile motion is a form of motion experienced by an object or particle (a projectile) that is projected in a gravitational field, such as from Earth's surface, and moves along a curved path under the action of gravity only. In the particular case of projectile motion of Earth, most calculations assume the effects of air resistance are passive and negligible. The curved path of objects in projectile motion was shown by Galileo to be a parabola, but may also be a straight line in the special case when it is thrown directly upwards. The study of such motions is called ballistics, and such a trajectory is a ballistic trajectory. The only force of mathematical significance that is actively exerted on the object is gravity, which acts downward, thus imparting to the object a downward acceleration towards the Earth’s center of mass. Because of the object's inertia, no external force is needed to maintain the horizontal velocity component of the object's motion. Taking other fo ...

Red Fuming Nitric Acid
Red fuming nitric acid (RFNA) is a storable oxidizer used as a rocket propellant. It consists of 84% nitric acid (), 13% dinitrogen tetroxide and 1–2% 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. 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 fluoride for instance will passivate the container metal with a thin layer of metal fluoride, making it nearly impervious to the nitric acid. It can also be a component of a monopropellant; with substances like amine nitrates dissolved in it, it can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
