Its customers included France, the United States, Russia, India and other countries. History SEMT. was created in 1946 by France's ministry for industrial production by combining five national companies: * (Saint-Nazaire), * ( La Courneuve) * ( Le Havre) * (Nantes) * ( Denain) The aim of the new company was to develop new engines in France that could be licensed internationally. In 1948, the first licenses were supplied to licensed engine building companies worldwide. In 1951, after its relocation at La Courneuve, the was equipped with the first test beds. The equipment, which enabled the company to speed up the development of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Logo SEMT Pielstick Bleu
A logo (abbreviation of logotype; ) is a graphic mark, emblem, or symbol used to aid and promote public identification and recognition. It may be of an abstract or figurative design or include the text of the name it represents as in a wordmark. In the days of hot metal typesetting, a logotype was one word cast as a single piece of type (e.g. "The" in ATF Garamond), as opposed to a ligature, which is two or more letters joined, but not forming a word. By extension, the term was also used for a uniquely set and arranged typeface or colophon. At the level of mass communication and in common usage, a company's logo is today often synonymous with its trademark or brand.Wheeler, Alina. ''Designing Brand Identity'' © 2006 John Wiley & Sons, Inc. (page 4) Etymology Douglas Harper's Online Etymology Dictionary states that the term 'logo' used in 1937 "probably a shortening of logogram".

Floréal-class Frigate
The ''Floréal'' class is a type of light "surveillance frigates" (french: frégate de surveillance) designed for the needs of the French Navy in low-threat environments ordered in 1989. The ships are named after months of the Republican Calendar. They use construction standards of commercial ships. The frigates were built between 1990 and 1993 by the Chantiers de l'Atlantique at Saint-Nazaire, France. The six French ships of the class, , , , , and , remain in active service. The ships' main armament was two Exocet MM38 surface-to-surface missiles and a CADAM turret, but in 2014, the Exocets were removed at the end of their life cycle. The vessels have a maximum speed of and can carry 24 marines. The vessels are used mainly to patrol the French overseas departments and regions in the Pacific, Indian Ocean and Caribbean regions, but have served in both military and humanitarian operations in the Persian Gulf and the Gulf of Guinea. Two more ships were ordered by the Royal M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Georges Leygues-class Frigate
The ''Georges Leygues'' class (Type C70 AS or Type F70 AS) was a class of anti-submarine destroyers of the French Navy. They were multi-role ships due to their Exocet and Crotale missile armament, making them especially suitable for the defence of strategic positions, show of force operations, or as high seas escorts. The design was initially officially known as a " corvette" with the designation C70, but were internationally labelled an "anti-submarine destroyer" (hence the "D" in the hull numbers). Subsequently, the French referred to the ships as "frigates" with the designation F70. Design The superstructures were built to optimise resistance to the blast from nuclear explosions. The last three ships of the class had their bridges raised one deck to overcome problems experienced by the first four in bad weather, as well as being equipped with DSBV 61 passive linear towed array sonar and several other upgraded systems.

International Union Of Railways
The International Union of Railways (UIC, french: Union internationale des wikt:chemin de fer, chemins de fer) is an international rail transport industry body. History The railways of Europe originated as many separate concerns, and there were many border changes after World War I and the Treaty of Versailles. Colonial railways were the responsibility of the mother country. Into this environment the UIC was created on 17 October 1922, with the aim of standardising industry practices. Ticket revenue sharing was originally undertaken with the UIC Franc currency equivalent. UIC classification and UIC Country Codes allowed precise determination of rolling stock capabilities and ownership, with wagons assigned unique UIC wagon numbers. The 1990s GSM-R radio telecommunication system is an international interoperability specification covering voice and signalling systems for railway communications whose specification is maintained by the International Union of Railways project Euro ...

Turbocharger
In an internal combustion engine, a turbocharger (often called a turbo) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake gas, forcing more air into the engine in order to produce more power for a given displacement. The current categorisation is that a turbocharger is powered by the kinetic energy of the exhaust gasses, whereas a supercharger is mechanically powered (usually by a belt from the engine's crankshaft). However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger. History Prior to the invention of the turbocharger, |

Submarine
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and Autonomous underwater vehicle, robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navy, navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, Blockade runner, blockade running, Ballistic missile submarine, nuclear deterrence, reconnaissance, conventio ...

Four-stroke Engine
A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed: #Intake: Also known as induction or suction. This stroke of the piston begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.). In this stroke the intake valve must be in the open position while the piston pulls an air-fuel mixture into the cylinder by producing vacuum pressure into the cylinder through its downward motion. The piston is moving down as air is being sucked in by the downward motion against the piston. #Compression: This stroke begins at B.D.C, or just at the end of the suction stroke, and ends at T.D.C. In this stroke the piston compresses the air-fuel mixture in preparation for ignition during the power stroke (below). Both the intake and exhaust valves are close ...

Long-stroke Engine
In a reciprocating piston engine, the stroke ratio, defined by either bore/stroke ratio or stroke/bore ratio, is a term to describe the ratio between cylinder bore diameter and piston stroke length. This can be used for either an internal combustion engine, where the fuel is burned within the cylinders of the engine, or external combustion engine, such as a steam engine, where the combustion of the fuel takes place ''outside'' the working cylinders of the engine. A fairly comprehensive yet understandable study of stroke/bore effects was published in ''Horseless Age'', 1916. Conventions In a piston engine, there are two different ways of describing the ''stroke ratio'' of its cylinders, namely: ''bore/stroke'' ratio, and ''stroke/bore'' ratio. Bore/stroke ratio Bore/stroke is the more commonly used term, with usage in North America, Europe, United Kingdom, Asia, and Australia. The diameter of the cylinder bore is divided by the length of the piston stroke to give the r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
