Contraves Cora
The Cora was a digital fire-control system designed by Hungarian-Swiss Peter Tóth and produced by the Swiss company Contraves. Development Peter Tóth started the design of ''Cora-1'' in 1957. The system was intended for anti-aircraft fire direction with the Swiss Army.Un ordinateur historique retrouvé dans les caves de l’EPFL , ''24 Heures'' However, ''Cora-1'' turned out to be too slow and too bulky for this application. It was programmed for other applications by programmers including Heinz Lienhard. One copy of the system was used at the |
Contraves
Rheinmetall Air Defence AG is a division of German armament manufacturer Rheinmetall, created when the company's Oerlikon Contraves unit was renamed on 1 January 2009 and integrated with Rheinmetall's other air-defence products. Oerlikon Contraves was a Swiss anti-aircraft artillery manufacturer famous for its adaptation of the 1916 Becker Type M2 20 mm cannon, 20 mm Becker as the Oerlikon 20 mm cannon, Oerlikon 20 mm autocannon design, which was used in the Second World War and remains in use. Copies and derivatives of these designs were made by German, French, British, and Japanese weapon manufacturers. Oerlikon Contraves was purchased by Rheinmetall in 1999. , Rheinmetall Air Defence had around 1,050 employees at locations in Switzerland, Germany, Italy, and Canada. The group's sales were about . History Oerlikon's earliest predecessor was Maschinenfabrik Oerlikon, Schweizerische Werkzeugmaschinenfabrik Oerlikon, founded in the Oerlikon (Zürich), Oerlikon district of Zü ...

Ballistics
Ballistics is the field of mechanics concerned with the launching, flight behaviour and impact effects of projectiles, especially weapon munitions such as bullets, unguided bombs, rockets and 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 those 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 missile guidance, guided only during the relatively brief initial phase of powered flight, with the trajectory subsequently governed by the laws of classical mechanics, in contrast to (for example) a cruise missile, which is aerodynamics, aerodynamically guided in powered flight like a fixed-wing aircraft. History and prehistory The earliest known ballistic projectiles were stones, spears, and the throwing s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Artillery Operation
Artillery consists of ranged weapons that launch munitions far beyond the range and power of infantry firearms. Early artillery development focused on the ability to breach defensive walls and fortifications during sieges, and led to heavy, fairly immobile siege engines. As technology improved, lighter, more mobile field artillery cannons were developed for battlefield use. This development continues today; modern self-propelled artillery vehicles are highly mobile weapons of great versatility generally providing the largest share of an army's total firepower. Originally, the word "artillery" referred to any group of soldiers primarily armed with some form of manufactured weapon or armour. Since the introduction of gunpowder and cannon, "artillery" has largely meant cannon, and in contemporary usage, usually refers to shell-firing guns, howitzers, and mortars (collectively called ''barrel artillery'', ''cannon artillery'' or ''gun artillery'') and rocket artillery. In common ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Military Computers
This article specifically addresses U.S. armed forces military computers and their use. History Some of the earliest computers were military computers. Military requirements for portability and ruggedness led to some of the earliest transistorized computers, such as the 1958 AN/USQ-17, the 1959 AN/MYK-1 (MOBIDIC), the 1960 M18 FADAC, and the 1962 D-17B; the earliest integrated-circuit based computer, the 1964 D-37C; as well as one of the earliest laptop computers, the 1982 Grid Compass. Military requirements for a computer small enough to fit through a submarine's hatch led to the AN/UYK-1. Construction Typically a military computer is much more robust than an industrial computer enclosure. Most electronics will be protected with a layer of conformal coating. There will be more structure inside to support the components, the plug-in cards will be individually supported and secured to assure they do not pop out of their sockets, the processor and heat sink will be secured, mem ...

Von Neumann Architecture
The von Neumann architecture—also known as the von Neumann model or Princeton architecture—is a computer architecture based on the '' First Draft of a Report on the EDVAC'', written by John von Neumann in 1945, describing designs discussed with John Mauchly and J. Presper Eckert at the University of Pennsylvania's Moore School of Electrical Engineering. The document describes a design architecture for an electronic digital computer made of "organs" that were later understood to have these components: * A processing unit with both an arithmetic logic unit and processor registers * A control unit that includes an instruction register and a program counter * Memory that stores data and instructions * External mass storage * Input and output mechanisms.. The attribution of the invention of the architecture to von Neumann is controversial, not least because Eckert and Mauchly had done a lot of the required design work and claim to have had the idea for stored programs ...

Expo 64
The Swiss national exposition of 1964 (French: ''Exposition nationale suisse de 1964''), usually shortened to Expo 64, was the 5th swiss national exhibiton held in Lausanne, more specifically in Vidy and the neighbouring Vallée de la Jeunesse, between 30 April and 25 October 1964. Expo 64 was directed by Gabriel Despland, with Alberto Camenzind as chief architect, Edmond Henri as administrative director, and Paul Ruckstuhl as financial director. The syndic of Lausanne, Georges-André Chevallaz, was also part of the direction committee. Sectors Expo 64 was divided into eight sectors: *''La Voie Suisse'' ("the Swiss way"): main sector of Expo 64, devoted to the history, political system, cultural values and future perspectives of Switzerland * ''L'art de vivre'' ("art of life"): devoted to the resources of the 1960s, such as the environment, the way of life and spiritual aspirations. * ''Communications et transports'' ("Communications and transports"): Communications, transpor ...

Fire-control System
A fire-control system (FCS) is a number of components working together, usually a gun data computer, a director and radar, which is designed to assist a ranged weapon system to target, track, and hit a target. It performs the same task as a human gunner firing a weapon, but attempts to do so faster and more accurately. Naval fire control Origins The original fire-control systems were developed for ships. The early history of naval fire control was dominated by the engagement of targets within visual range (also referred to as direct fire). In fact, most naval engagements before 1800 were conducted at ranges of . Even during the American Civil War, the famous engagement between and was often conducted at less than range. Rapid technical improvements in the late 19th century greatly increased the range at which gunfire was possible. Rifled guns of much larger size firing explosive shells of lighter relative weight (compared to all-metal balls) so greatly increased the ...

Cartography
Cartography (; from , 'papyrus, sheet of paper, map'; and , 'write') is the study and practice of making and using maps. Combining science, aesthetics and technique, cartography builds on the premise that reality (or an imagined reality) can be modeled in ways that communicate spatial information effectively. The fundamental objectives of traditional cartography are to: * Set the map's agenda and select traits of the object to be mapped. This is the concern of map editing. Traits may be physical, such as roads or land masses, or may be abstract, such as toponyms or political boundaries. * Represent the terrain of the mapped object on flat media. This is the concern of map projections. * Eliminate the mapped object's characteristics that are irrelevant to the map's purpose. This is the concern of Cartographic generalization, generalization. * Reduce the complexity of the characteristics that will be mapped. This is also the concern of generalization. * Orchestrate the elements ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
