Musudan (missile)
The Hwasong-10 () is a mobile intermediate-range ballistic missile developed by North Korea. Description Hwasong-10 is a missile that is based on R-27 Zyb submarine-launched ballistic missile, but is slightly longer. It used a hypergolic combination of unsymmetrical dimethylhydrazine (UDMH) as fuel and nitrogen tetroxide (NTO) as oxidizer, which is similar to the liquid-fueled 4D10 engine of R-27. These propellants are much more advanced than the kerosene compounds used in North Korea's Scud and Hwasong-7 (Nodong) missiles. Once the fuel/oxidizer combination are fed into the missile, it could maintain a 'ready to launch' condition for several days, or even weeks, like the R-27 SLBM, in moderate ambient temperatures. A fueled Hwasong-10 would not have the structural strength to be safely land-transported, so the missile would have to be fueled at the launch site. It was originally believed that the rocket motors of Hwasong-10 were the same as those within the second stage of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Musu Dan
Musu Point or Musu Dan (; "Cape of the Dancing Water(s)") is a North Korean headland in the middle of the country's eastern coast along the Sea of Japan. It forms the eastern side of North Hamgyong's Hwadae County and the northern point of East Korea Bay. Names In the 19th century, Musu Point was variously known as .. or . It was known in Korean as .. During the Japanese occupation of Korea, it was known as Geography Musu Point is a promontory consisting of high reddish cliffs projecting boldly south but tapering down to the sea at its apex, which marks the northern end of East Korea Bay. It also forms the eastern end of a narrow but deep bay extending about west to Yongdae Gap.. The peak of the mountain forming the cape has been reckoned as . A rock high lies just south of the point.

Unsymmetrical Dimethylhydrazine
Unsymmetrical dimethylhydrazine (abbreviated as UDMH; also known as 1,1-dimethylhydrazine, heptyl or Geptil) is a chemical compound with the formula H2NN(CH3)2 that is primarily used as a rocket propellant. At room temperature, UDMH is a colorless liquid, with a sharp, fishy, ammonia-like smell typical of organic amines. Samples turn yellowish on exposure to air and absorb oxygen and carbon dioxide. It is miscible with water, ethanol, and kerosene. At concentrations between 2.5% and 95% in air, its vapors are flammable. It is not sensitive to shock. Symmetrical dimethylhydrazine (1,2-dimethylhydrazine) also exists, but it is not as useful. UDMH can be oxidized in air to form many different substances, including toxic ones. Synthesis In 1875, UDMH was first prepared by Emil Fischer, who discovered and named the class of hydrazines, by reducing N-Nitrosodimethylamine with zinc in boiling acetic acid. Fischer's student Edward Renouf later studied UDMH more extensively as part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lofted Trajectory
In physics, projectile motion describes the motion of an object that is launched into the air and moves under the influence of gravity alone, with air resistance neglected. In this idealized model, the object follows a parabolic path determined by its initial velocity and the constant acceleration due to gravity. The motion can be decomposed into horizontal and vertical components: the horizontal motion occurs at a constant velocity, while the vertical motion experiences uniform acceleration. This framework, which lies at the heart of classical mechanics, is fundamental to a wide range of applications—from engineering and ballistics to sports science and natural phenomena. Galileo Galilei showed that the trajectory of a given projectile is parabolic, but the path may also be straight in the special case when the object is thrown directly upward or downward. The study of such motions is called ballistics, and such a trajectory is described as ballistic. The only force of m ... [...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] |
Kerosene
Kerosene, or paraffin, is a combustibility, combustible hydrocarbon liquid which is derived from petroleum. It is widely used as a fuel in Aviation fuel, aviation as well as households. Its name derives from the Greek (''kērós'') meaning "wax"; it was registered as a trademark by Nova Scotian, Nova Scotia geologist and inventor Abraham Pineo Gesner, Abraham Gesner in 1854 before evolving into a generic trademark. It is sometimes spelled kerosine in scientific and industrial usage. Kerosene is widely used to power jet engines of aircraft (jet fuel), as well as some rocket engines in a highly refined form called RP-1. It is also commonly used as a cooking and lighting fuel, and for fire toys such as Poi (performance art)#Fire poi, poi. In parts of Asia, kerosene is sometimes used as fuel for small outboard motors or even motorcycles. World total kerosene consumption for all purposes is equivalent to about 5,500,000 barrels per day as of July 2023. The term "kerosene" is comm ...

Unha-3
The Unha (, "Galaxy") is a North Korean expendable carrier rocket, which partially utilizes the same delivery system as the Taepodong-2 orbital launch system. History North Korea's first orbital space launch attempt occurred on 31 August 1998, and was unsuccessful. This launch attempt was performed by a Paektusan-1 rocket, which used a solid motor third stage, a Scud-missile-based second stage, and a Hwasong-7 (Nodong-1) based first stage. Hwasong-7 was a North Korean-developed stage thought to be a scale-up of the old Soviet Scud missile. The Paektusan-1 stood tall, was in diameter, and weighed about 21 tonnes. Vehicle description The Unha's first stage consists of four clustered Nodong motors, which themselves are enlarged Scud motors. The second stage was initially thought to be based on the SS-N-6, although it, too, is now believed to be based on Scud technology. The third and last stage might be identical to the Iranian Safir's second stage which is propelled ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
