ML-20
The 152 mm howitzer-gun M1937 (ML-20) (russian: 152-мм гаубица-пушка обр. 1937 г. (МЛ-20)), is a Soviet heavy gun-howitzer. The gun was developed by the design bureau of the plant no 172, headed by F. F. Petrov, as a deep upgrade of the 152-mm gun M1910/34, in turn based on the 152-mm siege gun M1910, a pre-World War I design by Schneider. It was in production from 1937 to 1946. The ML-20 saw action in World War II, mainly as a corps / army level artillery piece of the Soviet Army. Captured guns were employed by Wehrmacht and the Finnish Army. Post World War II, the ML-20 saw combat in numerous conflicts during the mid to late twentieth century. Description The ML-20 was officially classified as howitzer-gun, i.e. an artillery system which combines characteristics of a howitzer and (to lesser extent) of a gun and therefore can be used in both roles. This universality was achieved by wide range of elevation angles and by using separate loading with 13 di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

152-mm Gun M1910/34
152-mm gun model 1910/34 (russian: 152-мм пушка образца 1910/34 годов) was a Soviet 152.4 mm (6 inch) heavy gun, a modernization of the 152-mm gun M1910/30, which in turn was based on 152-mm siege gun M1910. Description M1910/34 combined a barrel of the M1910/30 with a carriage of the 122-mm gun M1931. The barrel was of built-up construction; it was equipped with interrupted screw breechblock and recoil system consisting of hydraulic buffer and hydro-pneumatic recuperator. The split-trail carriage had leaf spring suspension and wheels with solid rubber tires. Development and production history The first upgrade of the 152-mm siege gun M1910 resulted in a weapon with improved characteristics, but didn't address some significant shortcomings, namely insufficient mobility (due to unsprung carriage and separate transportation of barrel) and limited traverse. The new modernization was an attempt to solve these problems by using a modern split trail c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gun-howitzer
Gun-howitzer (also referred to as gun howitzer) is a type of artillery weapon that is intended to fulfill both the role of ordinary cannon or field gun, and that of a howitzer. It is thus able to convey both direct and indirect fire. Modern gun-howitzers are usually identified just as howitzers. To be able to serve as a howitzer, gun-howitzers are typically built to achieve at least 60° to 70° of elevation. For effective direct fire, the gun-howitzers typically employ a fairly long gun barrel, usually not shorter than 30 calibres. Its ammunition also has a high muzzle velocity and usually of large calibre ( calibre and greater). History Historically the first gun-howitzer was the French ''canon obusier'' of the mid-19th century. The smooth-bore Canon obusier de 12 was a versatile weapon that quickly replaced both ordinary cannons and howitzers in French service, and became one of the basic types of artillery used by both sides of the American Civil War.

The Smolensk Region In The Years Of Great Patriotic War
''The'' () is a grammatical article in English, denoting persons or things that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pron ...

Howitzer
A howitzer () is a long- ranged weapon, falling between a cannon (also known as an artillery gun in the United States), which fires shells at flat trajectories, and a mortar, which fires at high angles of ascent and descent. Howitzers, like other artillery equipment, are usually organized in a group called a battery. Howitzers, together with long-barreled guns, mortars, and rocket artillery, are the four basic types of modern artillery. Mortars fire at angles of elevation greater than 45°, and are useful for mountain warfare because the projectile could go over obstacles. Cannons fire at low angles of elevation (<45°), and the projectile lands much faster at its target than it would in the case of a mortar. But the cannon is not useful if there is an obstacle like a hill/wall in front of its target. Etymology The English word ''howitzer'' comes from the Czech word , from , 'crowd', and is in turn a borrowing from the Middle High German word or (mode ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cannon
A cannon is a large- caliber gun classified as a type of artillery, which usually launches a projectile using explosive chemical propellant. Gunpowder ("black powder") was the primary propellant before the invention of smokeless powder during the late 19th century. Cannons vary in gauge, effective range, mobility, rate of fire, angle of fire and firepower; different forms of cannon combine and balance these attributes in varying degrees, depending on their intended use on the battlefield. A cannon is a type of heavy artillery weapon. The word ''cannon'' is derived from several languages, in which the original definition can usually be translated as ''tube'', ''cane'', or ''reed''. In the modern era, the term ''cannon'' has fallen into decline, replaced by ''guns'' or ''artillery'', if not a more specific term such as howitzer or mortar, except for high-caliber automatic weapons firing bigger rounds than machine guns, called autocannons.

Meteorological
Meteorology is a branch of the atmospheric sciences (which include atmospheric chemistry and physics) with a major focus on weather forecasting. The study of meteorology dates back millennia, though significant progress in meteorology did not begin until the 18th century. The 19th century saw modest progress in the field after weather observation networks were formed across broad regions. Prior attempts at prediction of weather depended on historical data. It was not until after the elucidation of the laws of physics, and more particularly in the latter half of the 20th century the development of the computer (allowing for the automated solution of a great many modelling equations) that significant breakthroughs in weather forecasting were achieved. An important branch of weather forecasting is marine weather forecasting as it relates to maritime and coastal safety, in which weather effects also include atmospheric interactions with large bodies of water.

Ballistics
Ballistics is the field of mechanics concerned with the launching, flight behaviour and impact effects of projectiles, especially ranged weapon munitions such as bullets, unguided bombs, rockets or the like; the science or art of designing and accelerating projectiles so as to achieve a desired performance. A ballistic body is a free-moving body with momentum which can be subject to forces such as the forces exerted by pressurized gases from a gun barrel or a propelling nozzle, normal force by rifling, and gravity and air drag during flight. A ballistic missile is a missile that is guided only during the relatively brief initial phase of powered flight and the trajectory is subsequently governed by the laws of classical mechanics; in contrast to (for example) a cruise missile which is aerodynamically guided in powered flight like a fixed-wing aircraft. History and prehistory The earliest known ballistic projectiles were stones and spears, and the throwing stick. The oldes ...

Slide Rule
The slide rule is a mechanical analog computer which is used primarily for multiplication and division, and for functions such as exponents, roots, logarithms, and trigonometry. It is not typically designed for addition or subtraction, which is usually performed using other methods. Maximum accuracy for standard linear slide rules is about three decimal significant digits, while scientific notation is used to keep track of the order of magnitude of results. Slide rules exist in a diverse range of styles and generally appear in a linear, circular or cylindrical form, with slide rule scales inscribed with standardized Graduation (instrument), graduated markings. Slide rules manufactured for specialized fields such as aviation or finance typically feature additional scales that aid in specialized calculations particular to those fields. The slide rule is closely related to nomograms used for application-specific computations. Though similar in name and appearance to a standard ruler ...

Gun Barrel
A gun barrel is a crucial part of gun-type weapons such as small firearms, artillery pieces, and air guns. It is the straight shooting tube, usually made of rigid high-strength metal, through which a contained rapid expansion of high-pressure gas(es) is used to propel a projectile out of the front end ( muzzle) at a high velocity. The hollow interior of the barrel is called the bore, and the diameter of the bore is called its caliber, usually measured in inches or millimetres. The first firearms were made at a time when metallurgy was not advanced enough to cast tubes capable of withstanding the explosive forces of early cannons, so the pipe (often built from staves of metal) needed to be braced periodically along its length for structural reinforcement, producing an appearance somewhat reminiscent of storage barrels being stacked together, hence the English name.''A History of Warfare'' - Keegan, John, Vintage 1993. History Gun barrels are usually metal. However, the e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
