CRV7
The CRV7, short for "Canadian Rocket Vehicle 7", is a 2.75-inch (70 mm) folding-fin ground attack rocket produced by Bristol Aerospace in Winnipeg, Manitoba. It was introduced in the early 1970s as an upgraded version of the standard U.S. 2.75-inch air-to-ground rockets. It was the most powerful weapon of its class, the first with enough energy to penetrate standard Warsaw Pact aircraft hangars. The CRV7 remains one of the most powerful air-to-ground attack rockets to this day, and has slowly become the de facto standard for Western-aligned forces outside the United States. Beginning in 2021, 83,303 stored Canadian CRV7s are slated for disposal having been removed from service from 2005 to 2007. Development The CRV7 was an offshoot of late 1950s research at CARDE into high-performance solid fuel rockets, performed as a part of a general program studying anti-ballistic missiles. With Aerojet's assistance, CARDE and Bristol developed the "Propulsion Test Vehicle" to test new fu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bristol Aerospace
Bristol Aerospace is a Canadian aerospace firm located in Winnipeg, Manitoba and is an operating division of Magellan Aerospace. Today it is the only remaining and surviving subsidiary of Bristol Aeroplane Company. History Bristol Aerospace began in 1930 as the MacDonald Brothers Aircraft Company. Brothers Jim and Grant MacDonald moved to Winnipeg from Nova Scotia in 1904 to start a sheet metal business. Brother Edwin joined them later and by the late 1920s air travel had become an important means of transportation with Winnipeg becoming a hub for travel to the booming west. The MacDonalds formed ''MacDonald Brothers Aircraft Company'' in 1930, producing seaplane floats under licence from EDO Corporation of New York City. The company produced floats into the early 1980s. WWII During World War II the factory built training aircraft and by war's end had grown to 4,500 employees. At the end of the war, MacDonald Bros. became an important repair and overhaul centre for the Royal C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
McDonnell Douglas CF-18 Hornet
The McDonnell Douglas CF-18 Hornet (official military designation CF-188) is a Royal Canadian Air Force (RCAF) variant of the American McDonnell Douglas F/A-18 Hornet fighter aircraft. In 1980, the F/A-18 was selected as the winner of the New Fighter Aircraft Project competition and awarded a production order; deliveries of the CF-18 to the Canadian Armed Forces began in 1982. CF-18s have supported North American Aerospace Defense Command (NORAD) air sovereignty patrols and participated in combat during the Gulf War in 1991, the Kosovo War in the late 1990s, and as part of the Canadian contribution to the international Libyan no-fly zone in 2011. CF-18s were also part of the Canadian contribution to the military intervention against ISIL, Operation Impact. Development New Fighter Aircraft program In 1977, the Canadian government identified the need to replace the NATO-assigned CF-104 Starfighter, the NORAD-assigned CF-101 Voodoo and the CF-116 Freedom Fighter (although the de ...

Black Brant Rocket
The Black Brant is a family of Canadian-designed sounding rockets originally built by Bristol Aerospace, since absorbed by Magellan Aerospace in Winnipeg, Manitoba. Over 800 Black Brants of various versions have been launched since they were first produced in 1961, and the type remains one of the most popular sounding rockets. They have been repeatedly used by the Canadian Space Agency and NASA. History Black Brant was the result of research at Canadian Armament Research and Development Establishment (CARDE) during the 1950s into the nature of the upper part of the atmosphere as part of ongoing research into anti-ballistic missile systems and very-long-range communication. In 1957 CARDE contracted Bristol to produce a simple rocket fuselage, called the Propulsion Test Vehicle, for studies into high-power solid fuels. The resulting design, by Albert Fia, was quite heavy, as it was designed to be able to accommodate a wide variety of engine burning times, propellant loadings an ...

Anti-ballistic Missile
An anti-ballistic missile (ABM) is a surface-to-air missile designed to counter ballistic missiles (missile defense). Ballistic missiles are used to deliver nuclear weapon, nuclear, Chemical weapon, chemical, Bioagent, biological, or conventional weapon, conventional warheads in a ballistics, ballistic flight trajectory. The term "anti-ballistic missile" is a generic term conveying a system designed to intercept and destroy any type of ballistic threat; however, it is commonly used for systems specifically designed to counter intercontinental ballistic missiles (ICBMs). Current counter-ICBM systems There are a limited number of systems worldwide that can intercept intercontinental ballistic missiles: * The Russian A-135 anti-ballistic missile system (renamed in 2017 to A-235) is used for the defense of Moscow. It became operational in 1995 and was preceded by the A-35 anti-ballistic missile system. The system uses ABM-4 Gorgon, Gorgon and Gazelle (missile), Gazelle missiles pre ...

Aluminium
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity tow ...

Helicopters
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of STOL (Short TakeOff and Landing) or STOVL (Short TakeOff and Vertical Landing) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.Munson 1968.Hirschberg, Michael J. and David K. Dailey"Sikorsky". ''US and Russian Helicopter Development in the 20th Century'', American Helicopter Society, International. 7 July 2000. Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most common h ...

High-explosive
An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. The potential energy stored in an explosive material may, for example, be * chemical energy, such as nitroglycerin or grain dust * pressurized gas, such as a gas cylinder, aerosol can, or BLEVE * nuclear energy, such as in the fissile isotopes uranium-235 and plutonium-239 Explosive materials may be categorized by the speed at which they expand. Materials that detonate (the front of the chemical reaction moves faster through the material than the speed of sound) are said to be "high explosives" and materials that deflagrate are said to be "low explosives". Explosives may also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High Explosive Incendiary/Armor Piercing Ammunition
High-explosive incendiary/armor-piercing ammunition (HEIAP) is a form of shell which combines armor-piercing capability and a high-explosive effect. In this respect it is a modern version of an armor-piercing shell. The ammunition may also be called semi-armor-piercing high-explosive incendiary (SAPHEI) Typical of a modern HEIAP shell is the Raufoss Mk 211 designed for weapons such as heavy machine guns and anti-materiel rifles. The primary purpose of these munitions is armor penetration with better beyond-armor effects. Similarly to SLAP rounds (saboted light armor penetrator) which get their armor-piercing ability from the propulsion of a 7.62 mm tungsten heavy alloy bullet from a 12.7 mm barrel (.50 caliber) using a sabot with much more energy than is usually possible from a 7.62 mm round, HEIAP munitions utilize a similar theory with an added explosive effect at the end. The special effect is developed when the round strikes the target. The initial collision ignites the inc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flare (countermeasure)
A flare or decoy flare is an aerial infrared countermeasure used by a plane or helicopter to counter an infrared homing ("heat-seeking") surface-to-air missile or air-to-air missile. Flares are commonly composed of a pyrotechnic composition based on magnesium or another hot-burning metal, with burning temperature equal to or hotter than engine exhaust. The aim is to make the infrared-guided missile seek out the heat signature from the flare rather than the aircraft's engines. Tactics In contrast to radar-guided missiles, IR-guided missiles are very difficult to find as they approach aircraft. They do not emit detectable radar, and they are generally fired from behind, directly toward the engines. In most cases, pilots have to rely on their wingmen to spot the missile's smoke trail and alert of a launch. Since IR-guided missiles have a shorter range than their radar-guided counterparts, good situational awareness of altitude and potential threats continues to be an effective ...

M61 Vulcan
The M61 Vulcan is a hydraulically, electrically, or pneumatically driven, six-barrel, air-cooled, electrically fired Gatling-style rotary cannon which fires rounds at an extremely high rate (typically 6,000 rounds per minute). The M61 and its derivatives have been the principal cannon armament of United States military fixed-wing aircraft for over sixty years. The M61 was originally produced by General Electric. After several mergers and acquisitions, it is currently produced by General Dynamics. Development At the end of World War II, the United States Army Air Forces began to consider new directions for future military aircraft guns. The higher speeds of jet-powered fighter aircraft meant that achieving an effective number of hits would be extremely difficult without a much higher volume of fire. While captured German designs (principally the Mauser MG 213C) showed the potential of the single-barrel revolver cannon, the practical rate of fire of such a design was still lim ...
