East Pakistan
East Pakistan was a Pakistani province established in 1955 by the One Unit Scheme, One Unit Policy, renaming the province as such from East Bengal, which, in modern times, is split between India and Bangladesh. Its land borders were with India and Myanmar, with a coastline on the Bay of Bengal. East Pakistanis were popularly known as "Pakistani Bengalis"; to distinguish this region from India's state West Bengal (which is also known as "Indian Bengal"), East Pakistan was known as "Pakistani Bengal". In 1971, East Pakistan became the newly independent state Bangladesh, which means "country of Bengal" in Bengali. East Pakistan was renamed from East Bengal by the One Unit Scheme of Pakistani Prime Minister Mohammad Ali of Bogra. The Constitution of Pakistan of 1956 replaced the Pakistani monarchy with an Islamic republic. Bengali politician H. S. Suhrawardy served as the Prime Minister of Pakistan between 1956 and 1957 and a Bengali bureaucrat Iskander Mirza became the first Presid ...

Electrical Discharge Machine
Electrical discharge machining (EDM), also known as spark machining, spark eroding, die sinking, wire burning or wire erosion, is a metal fabrication process whereby a desired shape is obtained by using electrical discharges (sparks). Material is removed from the work piece by a series of rapidly recurring current discharges between two electrodes, separated by a dielectric liquid and subject to an electric voltage. One of the electrodes is called the tool-electrode, or simply the or , while the other is called the workpiece-electrode, or . The process depends upon the tool and work piece not making physical contact. When the voltage between the two electrodes is increased, the intensity of the electric field in the volume between the electrodes becomes greater, causing dielectric break down of the liquid, and produces an electric arc. As a result, material is removed from the electrodes. Once the current stops (or is stopped, depending on the type of generator), new liquid di ...

Feasibility Study
A feasibility study is an assessment of the practicality of a project or system. A feasibility study aims to objectively and rationally uncover the strengths and weaknesses of an existing business or proposed venture, opportunities and threats present in the natural environment, the resources required to carry through, and ultimately the prospects for success.Justis, R. T. & Kreigsmann, B. (1979). The feasibility study as a tool for venture analysis. ''Business Journal of Small Business Management'' 17 (1) 35-42. In its simplest terms, the two criteria to judge feasibility are cost required and value to be attained. A well-designed feasibility study should provide a historical background of the business or project, a description of the product or service, accounting statements, details of the operations and management, marketing research and policies, financial data, legal requirements and tax obligations. Generally, feasibility studies precede technical development and project ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Production Engineering
Manufacturing engineering or production engineering is a branch of professional engineering that shares many common concepts and ideas with other fields of engineering such as mechanical, chemical, electrical, and industrial engineering. Manufacturing engineering requires the ability to plan the practices of manufacturing; to research and to develop tools, processes, machines and equipment; and to integrate the facilities and systems for producing quality products with the optimum expenditure of capital. The manufacturing or production engineer's primary focus is to turn raw material into an updated or new product in the most effective, efficient & economic way possible. An example would be a company uses computer integrated technology in order for them to produce their product so that it is faster and uses less human labor. Overview Manufacturing Engineering is based on core industrial engineering and mechanical engineering skills, adding important elements from mechatronics, ...

Satellites
A satellite or artificial satellite is an object intentionally placed into orbit in outer space. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called transponders. Many satellites use a standardized bus to save cost and work, the most popular of which is small CubeSats. Similar satellites can work together as a group, forming constellations. Because of the high launch cost to space, satellites are designed to be as lightweight and robust as possible. Most communication satellites are radio relay stations in orbit and carry dozens of transponders, each with a bandwidth of tens of megahertz. Satellites are placed from the surface to orbit by launch vehicles, high enough to avoid orbital decay by the atmosphere. Satellites can then change or maintain the orbit by propulsion, ...

Entwicklungsring Nord
The Entwicklungsring Nord (Northern development circle) - abbreviated ERNO - was a 1961 joint venture of Bremen-based Weserflug and Focke-Wulf with Hamburger Flugzeugbau to develop parts for rockets and get involved in space activities. Jet-powered aircraft VFW 614 In 1961 work began on a small, jet-powered aircraft initially styled Erno-61-4. After Weserflug and Focke Wulf formally merged into Vereinigte Flugtechnische Werke (VFW) in 1964, the machine was redesignated VFW 614. The draft design was amended to a STOL 40-44 passenger jet with overwing engines, for easier operation from unprepared runways. German government subsidies enabled development to start in earnest in 1966. The first prototype started in August 1968, but then VFW and Fokker of the Netherlands formed a joint transnational holding company. The prototype flew on 14 July 1971 but crashed next February. Two more prototypes flew in 1972. German, FAA, and French DGA certifications completed in 1974, 1975, & 1976 resp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Technical Drawing
Technical drawing, drafting or drawing, is the act and Academic discipline, discipline of composing Plan (drawing), drawings that Visual communication, visually communicate how something functions or is constructed. Technical drawing is essential for communicating ideas in Manufacturing, industry and engineering. To make the drawings easier to understand, people use familiar symbols, Perspective (graphical), perspectives, units of measurement, notation systems, visual styles, and page layout. Together, such Convention (norm), conventions constitute a visual language and help to ensure that the drawing is unambiguous and relatively easy to understand. Many of the symbols and principles of technical drawing are codified in an international standard called ISO 128. The need for precise communication in the preparation of a functional document distinguishes technical drawing from the expressive drawing of the visual arts. Artistic drawings are subjectively interpreted; their meanin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown, Boveri & Cie
Brown, Boveri & Cie. (Brown, Boveri & Company; BBC) was a Swiss group of electrical engineering companies. It was founded in Zürich, in 1891 by Charles Eugene Lancelot Brown and Walter Boveri who worked at the Maschinenfabrik Oerlikon. In 1970 BBC took over the Maschinenfabrik Oerlikon. In 1988 it merged with ASEA to form ABB. Early History of BBC Brown Boveri BBC Brown Boveri was established in 1891. The company was one of only a few multinational corporations to operate subsidiaries that were larger than the parent company. Because of the limitations of the Swiss domestic market, Brown Boveri established subsidiaries throughout Europe relatively early in its history, and at times had difficulty maintaining managerial control over some of its larger operating units. The merger with ASEA, a company which was praised for its strong management, was expected to help Brown Boveri reorganize and reassert control over its vast international network. Activity in Britain Brown Bove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fighter Jets
Fighter aircraft are fixed-wing military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air superiority of the battlespace. Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical and strategic bombing of enemy targets. The key performance features of a fighter include not only its firepower but also its high speed and maneuverability relative to the target aircraft. The success or failure of a combatant's efforts to gain air superiority hinges on several factors including the skill of its pilots, the tactical soundness of its doctrine for deploying its fighters, and the numbers and performance of those fighters. Many modern fighter aircraft also have secondary capabilities such as ground attack and some types, such as fighter-bombers, are designed from the outset for dual roles. Other fighter designs are highly specialized while still filling the main a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wings
A wing is a type of fin that produces lift while moving through air or some other fluid. Accordingly, wings have streamlined cross-sections that are subject to aerodynamic forces and act as airfoils. A wing's aerodynamic efficiency is expressed as its lift-to-drag ratio. The lift a wing generates at a given speed and angle of attack can be one to two orders of magnitude greater than the total drag on the wing. A high lift-to-drag ratio requires a significantly smaller thrust to propel the wings through the air at sufficient lift. Lifting structures used in water include various foils, such as hydrofoils. Hydrodynamics is the governing science, rather than aerodynamics. Applications of underwater foils occur in hydroplanes, sailboats and submarines. Etymology and usage For many centuries, the word "wing", from the Old Norse ''vængr'', referred mainly to the foremost limbs of birds (in addition to the architectural aisle). But in recent centuries the word's meaning has exte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vereinigte Flugtechnische Werke
Vereinigte Flugtechnische Werke (VFW) was a West German aerospace manufacturer. The company was formed by the 1964 merger of two German aerospace firms, Focke-Wulf and Weser Flugzeugbau GmbH (Weserflug). The formation of VFW was a natural outcome, as the two companies had been collaborating, along with Hamburger Flugzeugbau (HFB), in the rocket technology development alliance Entwicklungsring Nord (ERNO) group since 1961, the move was seen as a natural fit. Such collaborative efforts continued throughout VFW's operating years, not just through ERNO but also with the Dutch aircraft producer Fokker, who formed a joint venture with the firm, VFW-Fokker GmbH, during 1969 to promote. Collaboration with Fokker waned substantially over the years, having been greatly soured by the poor results of the VFW 614 programme, resulting in VFW-Fokker GmbH being wound up in 1980. During 1981, VFW was acquired by its domestic rival, Messerschmitt-Bölkow-Blohm (MBB), and was largely integrated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
