Commonwealth Of Independent States
The Commonwealth of Independent States (CIS) is a regional organization, regional intergovernmental organization in Eurasia. It was formed following the dissolution of the Soviet Union, dissolution of the Soviet Union in 1991. It covers an area of and has an estimated population of 246,200,194. The CIS encourages cooperation in economic, political, and military affairs and has certain powers relating to the coordination of trade, finance, lawmaking, and security, including cross-border crime prevention. As the Soviet Union disintegrated, Byelorussian SSR, Belarus, Russian SFSR, Russia, and Ukrainian SSR, Ukraine signed the Belovezha Accords on 8 December 1991, declaring that the Union had effectively ceased to exist and proclaimed the CIS in its place. On 21 December, the Alma-Ata Protocol was signed, but Estonia, Latvia and Lithuania chose not to participate. Georgia (country), Georgia withdrew its membership in 2008 following Russo-Georgian War, a war with Russia. Ukraine f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sponson
Sponsons are projections extending from the sides of land vehicles, aircraft or watercraft to provide protection, Instantaneous stability, stability, storage locations, mounting points for weapons or other devices, or equipment housing. Watercraft On watercraft, a sponson is a projection that extends outward (usually from the hull, but sometimes other parts of the vessel) to improve stability while floating, or to act as a securing point for other equipment. Vessels with unstable body shapes or unevenly distributed weight are likely to feature sponsons to help prevent capsizing or other instabilities. On many vessels, these projections from the main body of the vessel can be attached and removed quickly and fairly easily. Canoes and kayaks sometimes feature sponson attachments as well, for stability in rough waters. These differ from outrigger boat, outriggers, which extend a significant distance away from the body of the craft, and are employed on craft designed for open waters. ...

Self-sealing Fuel Tank
A self-sealing fuel tank (SSFT) is a type of fuel tank, typically used in aircraft fuel tanks or fuel bladders, that prevents them from leaking fuel and igniting after being damaged. Typical self-sealing tanks have layers of rubber and reinforcing fabric, one of vulcanized rubber and one of untreated natural rubber, which can absorb fuel when it comes into contact with it. When a fuel tank is punctured the fuel seeps into these layers, causing the untreated layer to swell, closing and thus sealing the puncture. A similar concept is also employed for making self-sealing run-flat tires. History World War I George J. Murdock applied for the patent "War Aeroplane Fuel Tanks" on February 7, 1917 but was temporarily blocked by an order of the Federal Trade Commission, on February 6, 1918, to keep any discussion or publication of the invention secret. The order was rescinded by the United States Patent Office on September 26, 1918 and Murdock was eventually granted "Self-Punctur ...

Modularity
Modularity is the degree to which a system's components may be separated and recombined, often with the benefit of flexibility and variety in use. The concept of modularity is used primarily to reduce complexity by breaking a system into varying degrees of interdependence and independence across and "hide the complexity of each part behind an abstraction and interface". However, the concept of modularity can be extended to multiple disciplines, each with their own nuances. Despite these nuances, consistent themes concerning modular systems can be identified. Composability is one of the tenets of functional programming. This makes functional programs modular. Contextual nuances The meaning of the word "modularity" can vary somewhat based on context. The following are contextual examples of modularity across several fields of science, technology, industry, and culture: Science *In biology, modularity recognizes that organisms or metabolic pathways are composed of modules. *I ...

Gearbox
A transmission (also called a gearbox) is a mechanical device invented by Louis Renault (who founded Renault) which uses a gear set—two or more gears working together—to change the speed, direction of rotation, or torque multiplication/reduction in a machine. Transmissions can have a single fixed-gear ratio, multiple distinct gear ratios, or continuously variable ratios. Variable-ratio transmissions are used in all sorts of machinery, especially vehicles. Applications Early uses Early transmissions included the right-angle drives and other gearing in windmills, horse-powered devices, and steam-powered devices. Applications of these devices included pumps, mills and hoists. Bicycles Bicycles traditionally have used hub gear or Derailleur gear transmissions, but there are other more recent design innovations. Automobiles Since the torque and power output of an internal combustion engine (ICE) varies with its rpm, automobiles powered by ICEs require multiple ...

FADEC
A full authority digital engine (or electronics) control (FADEC) is a system consisting of a digital computer, called an "electronic engine controller" (EEC) or " engine control unit" (ECU), and its related accessories that control all aspects of aircraft engine performance. FADECs have been produced for both piston engines and jet engines. History The goal of any engine control system is to allow the engine to perform at maximum efficiency for a given condition. Originally, engine control systems consisted of simple mechanical linkages connected physically to the engine. By moving these levers the pilot or the flight engineer could control fuel flow, power output, and many other engine parameters. The mechanical/hydraulic engine control unit for Germany's BMW 801 piston aviation radial engine of World War II was just one notable example of this in its later stages of development. This mechanical engine control was progressively replaced first by analogue electronic engine cont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurocopter AS332
The Airbus Helicopters H215 (formerly Eurocopter AS332 Super Puma) is a four-bladed, twin-engined, medium-sized, utility helicopter developed and initially produced by French aerospace company Aérospatiale. It has been subsequently manufactured by the successor companies Eurocopter and Airbus Helicopters. The Super Puma is a re-engined and larger version of the original Aérospatiale SA 330 Puma. Development of the Super Puma was carried out during the 1970s, based on the successful SA 330 Puma. While retaining a similar layout, the fuselage was redesigned to increase its damage tolerance and crashworthiness, while composite materials were also more extensively used. Furthermore, a pair of more powerful Turbomeca Makila turboshaft engines was also adopted, along with a more streamlined nose, amongst other changes. Two distinct fuselage lengths, a shortened and stretched form, were developed from the onset. On 5 September 1977, the ''SA 331'' preproduction prototype performed it ...
