Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French Navy
The French Navy (french: Marine nationale, lit=National Navy), informally , is the maritime arm of the French Armed Forces and one of the five military service branches of France. It is among the largest and most powerful naval forces in the world, ranking seventh in combined fleet tonnage and fifth in number of naval vessels. The French Navy is one of eight naval forces currently operating fixed-wing aircraft carriers,Along with the U.S., U.K., China, Russia, Italy, India and Spain with its flagship being the only nuclear-powered aircraft carrier outside the United States Navy, and one of two non-American vessels to use catapults to launch aircraft. Founded in the 17th century, the French Navy is one of the oldest navies still in continual service, with precursors dating back to the Middle Ages. It has taken part in key events in French history, including the Napoleonic Wars and both world wars, and played a critical role in establishing and securing the French colonial ...

Submarine Classes
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 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 navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, blockade running, nuclear deterrence, reconnaissance, conventional land attack (for example, using a cruise missile), and covert insertion of ...

Arsenal De Cherbourg
Cherbourg Naval Base is a naval base in Cherbourg Harbour, Cherbourg, Manche Departments of France, department, Normandy. The town has been a base of the French Navy since the opening of the military port in 1813. History Early works Cherbourg had been a stronghold since Roman times, and was one of the strongest fortresses of the Hundred Years War. But until the 18th century it had only a shallow harbour, minor commercial activity and no military development. In the 17th century the military engineer Sébastien Le Prestre de Vauban, Vauban drew up plans to develop Cherbourg into a port where passing ships could shelter from attack or storms. Vauban's plans included an artificial harbour, and the quadrupling of the size of the city. The project was eventually abandoned, before being temporarily revived under Louis XV of France, Louis XV. The British raid on Cherbourg in 1758 however caused severe damage to the barely completed commercial port. By the 1770s, with French involvement ...

Arsenal De Toulon
The military port of Toulon (french: arsenal de Toulon) is the principal base of the French Navy and the largest naval base in the Mediterranean, sited in the city of Toulon. It holds most of France's force d'action navale, comprising the aircraft carrier ''Charles de Gaulle'' as well as its nuclear attack submarines, in total, the base contains more than 60% of the French Navy's tonnage, and about 20,000 military and civilian personnel work at the base. The ''Rade'' The word ''rade'' comes from the old English term 'Road,' "a protected place near shore, not so enclosed as a harbour, where ships can ride at anchor.". The Rade of Toulon is one of the best natural anchorages on the Mediterranean, and the largest rade in Europe. It is protected from the sea by the peninsula of Giens and the peninsula of Saint-Mandrier-sur-Mer, and has been used as a military harbour since the 15th century. The Rade shelters the port of Saint-Mandrier-sur-Mer, the port of La Seyne-sur-Mer, as we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arsenal De Rochefort
The Arsenal de Rochefort was a French naval base and dockyard in the town of Rochefort. It was founded in 1665 and it was closed in 1926. In December 1665 Rochefort was chosen by Jean-Baptiste Colbert as a place of "refuge, defense and supply" for the French Navy. Its military harbour was fortified by Louis XIV's Commissary of Fortifications Sébastien Le Prestre de Vauban. Between 1666 and 1669 the King had the ''Corderie Royale'' (then the longest building in Europe) constructed to make cordage for French ships of war. The making of cordage ceased in 1867 and in 1926 the Arsenal de Rochefort was closed.

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electric Motor
An electric motor is an Electric machine, electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a Electromagnetic coil, wire winding to generate force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy. Electric motors can be powered by direct current (DC) sources, such as from batteries, or rectifiers, or by alternating current (AC) sources, such as a power grid, Inverter (electrical), inverters or electrical generators. Electric motors may be classified by considerations such as power source type, construction, application and type of motion output. They can be powered by AC or DC, be Brushed motor, brushed or Brushless motor, brushless, single-phase, Two-phase electric power, two-p ...

Deck Gun
A deck gun is a type of naval artillery mounted on the deck of a submarine. Most submarine deck guns were open, with or without a shield; however, a few larger submarines placed these guns in a turret. The main deck gun was a dual-purpose weapon used to sink merchant shipping or shell shore targets, or defend the submarine on the surface from enemy aircraft and warships. Typically a crew of three operated the gun, while others were tasked with supplying ammunition. A small locker box held a few 'ready-use' rounds. With a well-drilled, experienced crew, the rate of fire of a deck gun could be 15 to 18 aimed shots per minute. Some submarines also had additional deck guns like auto-cannons and machine guns for anti-aircraft defense. While similar unenclosed guns are often found on surface warships as secondary or defensive armament (such as the US Navy's 5-inch (127 mm)/25 caliber gun which was removed from battleships to mount on submarines), the term "deck gun" normally r ...

Hotchkiss Gun
The Hotchkiss gun can refer to different products of the Hotchkiss arms company starting in the late 19th century. It usually refers to the 1.65-inch (42 mm) light mountain gun; there were also a navy (47 mm) and a 3-inch (76 mm) Hotchkiss guns. The 42 mm gun was intended to be mounted on a light carriage or packed on two mules to accompany a troop of cavalry or an army travelling in rough country. Descriptions 1.65-inch gun The gun and accessories could be packed on two mules. The gun was introduced as a modern replacement for the aging twelve-pounder mountain howitzer. The first gun purchased by the U.S. military from the French arms firm of Hotchkiss was employed against the Nez Percé in 1877. Over the next twenty years the U.S. purchased 56. They were used at the Wounded Knee Massacre in 1890, and again in Cuba at the Battle of Las Guasimas, the Battle of El Caney and the attack on San Juan Hill during the Spanish–American War of 1898. ...
