Burya
The ''Burya'' ("Storm" in Russian; ) was a supersonic, intercontinental cruise missile, developed by the Lavochkin design bureau (chief designer Naum Semyonovich Chernyakov) under designation La-350 () from 1954 until the program cancellation in February 1960. The request for proposal issued by the Soviet government in 1954, called for a cruise missile capable of delivering a nuclear payload to the United States. Analogous developments in the United States were the SM-62 Snark and SM-64 Navaho cruise missiles, particularly the latter, which used parallel technology and had similar performance goals. Development The first steps towards development of Burya was the idea of Mstislav Vsevolodovich Keldysh of Keldysh bomber. The Burya was planned as a Mach 3 intercontinental nuclear ramjet cruise missile. The Burya was remarkably advanced for its time, and despite setbacks and several crashes, the vehicle demonstrated a range in excess of 6,000 km with a thermonuclear (hydr ...

RSS-40 Buran
The Buran (, named for the Buran wind) cruise missile, designation M-40 (М-40) sometimes referred to as ''RSS-40'', was a Soviet Union, Soviet intercontinental cruise missile by Myasishchev capable of carrying a 3,500 kg hydrogen bomb payload. The project was canceled before flight tests began. It is unrelated to the later Buran (spacecraft), Buran Orbiter, reusable orbiter. Development The project was authorized on 20 May 1954, parallel to the development of the Burya missile. The development however, began in April 1953 as a rocket-aircraft system by Myasishchev OKB with internal designation M-40. The project was canceled in November 1957, when two prototypes were just ready for flight testing, in favor of the R-7 Semyorka, since ICBMs were considered unstoppable. Like the Burya, the Buran consisted of two stages, the booster rockets designated M-41, and the cruise missile stage designated M-42.

SM-64 Navaho
The North American SM-64 Navaho was a supersonic intercontinental cruise missile project built by North American Aviation (NAA). The final design was capable of delivering a nuclear weapon to the USSR from bases within the US, while cruising at at altitude. The missile is named after the Navajo Nation. The original 1946 project called for a relatively short-range system, a boost-glide weapon based on a winged V-2 rocket design. Over time the requirements were repeatedly extended, both due to the US Air Force's desire for longer ranged systems, as well as competition from similar weapons that successfully filled the shorter-range niche. This led to a new design based on a ramjet powered cruise missile, which also developed into a series of ever-larger versions, along with the booster rockets to launch them up to speed. Through this period the US Air Force was developing the SM-65 Atlas, based on rocket technology developed for Navaho. Atlas filled the same performance goals but ...

Keldysh Bomber
The Keldysh bomber was a Soviet design for a rocket-powered sub-orbital bomber spaceplane, which drew heavily upon work carried out by Eugen Sänger and Irene Bredt for the German Silbervogel project. Development During the closing weeks of World War II, the German work at Peenemünde was investigated by Soviet intelligence, amongst whom was rocket motor constructor Aleksei Isaev, who found a copy of Sänger and Bredt's report. A translation was soon circulating among Soviet rocket designers, and a condensed version made its way to Stalin himself. In November 1946 the NII-1 NKAP research institute was formed with mathematician Mstislav Keldysh as its head to investigate and develop the German Sänger–Bredt design. In 1947, studies indicated that the high fuel consumption of Sänger's rocket-based design rendered the concept impracticable in the short term. Using engines considered to be available in a reasonable timespan, 95% of the vehicle's initial mass would have to be pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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.

Ramjet
A ramjet is a form of airbreathing jet engine that requires forward motion of the engine to provide air for combustion. Ramjets work most efficiently at supersonic speeds around and can operate up to . Ramjets can be particularly appropriate in uses requiring a compact mechanism for high-speed, such as missiles. Weapons designers are investigating ramjet technology for use in artillery shells to increase range; a 120 mm ramjet-assisted mortar shell is thought to be able to travel . They have been used, though not efficiently, as tip jets on the ends of helicopter rotors. History France Cyrano de Bergerac ''L'Autre Monde: ou les États et Empires de la Lune ( Comical History of the States and Empires of the Moon)'' (1657) was the first of three satirical novels written by Cyrano de Bergerac that are considered among the first science fiction stories.

Supersonic Cruise Missiles
Supersonic speed is the speed of an object that exceeds the speed of sound (Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level, this speed is approximately . Speeds greater than five times the speed of sound (Mach 5) are often referred to as hypersonic. Flights during which only some parts of the air surrounding an object, such as the ends of rotor blades, reach supersonic speeds are called transonic. This occurs typically somewhere between Mach 0.8 and Mach 1.2. Sounds are traveling vibrations in the form of pressure waves in an elastic medium. Objects move at supersonic speed when the objects move faster than the speed at which sound propagates through the medium. In gases, sound travels longitudinally at different speeds, mostly depending on the molecular mass and temperature of the gas, and pressure has little effect. Since air temperature and composition varies significantly with altitude, the speed of so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Amine
In chemistry, amines (, ) are organic compounds that contain carbon-nitrogen bonds. Amines are formed when one or more hydrogen atoms in ammonia are replaced by alkyl or aryl groups. The nitrogen atom in an amine possesses a lone pair of electrons. Amines can also exist as hetero cyclic compounds. Aniline is the simplest aromatic amine, consisting of a benzene ring bonded to an amino group. Amines are classified into three types: primary (1°), secondary (2°), and tertiary (3°) amines. Primary amines (1°) contain one alkyl or aryl substituent and have the general formula RNH2. Secondary amines (2°) have two alkyl or aryl groups attached to the nitrogen atom, with the general formula R2NH. Tertiary amines (3°) contain three substituent groups bonded to the nitrogen atom, and are represented by the formula R3N. The functional group present in primary amines is called the amino group. Classification of amines Amines can be classified according to the nature and number o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
