USS Corvina
USS ''Corvina'' (SS-226), a Gato class submarine, ''Gato''-class submarine, was the only ship of the United States Navy to be named for the Cilus gilberti, corvina. Construction and commissioning ''Corvina''′s keel was Keel-laying, laid down by the Electric Boat Company of Groton, Connecticut, on September 21, 1942. She was Ceremonial ship launching, launched on May 9, 1943, sponsored by Mrs. LaRene P. Christie, wife of Rear admiral (United States), Rear Admiral Ralph Waldo Christie, Ralph. W. Christie, commander of submarine operations in Fremantle, Australia, and Ship commissioning, commissioned on August 6, 1943. Service record Clearing New London, Connecticut, on September 18, 1943, ''Corvina '' arrived at Pearl Harbor on October 14. She put out from Pearl Harbor on her maiden war patrol November 4, topped up her fuel tanks at Johnston Island two days later, and was never heard from again. Her assignment had been a dangerous one: to patrol as closely as possible to the h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceremonial Ship Launching
Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and, in addition to the size and weight of the vessel, represents a considerable engineering challenge as well as a public spectacle. The process also involves many traditions intended to invite good luck, such as christening by breaking a sacrificial bottle of champagne over the bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The oldest, most familiar, and most widely used is th ...

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] |
