Alexander Hamilton
Alexander Hamilton (January 11, 1755 or 1757July 12, 1804) was an American military officer, statesman, and Founding Father who served as the first United States secretary of the treasury from 1789 to 1795. Born out of wedlock in Charlestown, Nevis, Hamilton was orphaned as a child and taken in by a prosperous merchant. He pursued his education in New York before serving as an artillery officer in the American Revolutionary War. Hamilton saw action in the New York and New Jersey campaign, served for years as an aide to General George Washington, and helped secure American victory at the Siege of Yorktown. After the war, Hamilton served as a delegate from New York to the Congress of the Confederation. He resigned to practice law and founded the Bank of New York. In 1786, Hamilton led the Annapolis Convention to replace the Articles of Confederation with the Constitution of the United States, which he helped ratify by writing 51 of the 85 installments of ''The Federalist ...

San Pedro, California
San Pedro ( ; Spanish: " St. Peter") is a neighborhood within the City of Los Angeles, California. Formerly a separate city, it consolidated with Los Angeles in 1909. The Port of Los Angeles, a major international seaport, is partially located within San Pedro. The district has grown from being dominated by the fishing industry, to a working-class community within the city of Los Angeles, to a rapidly gentrifying community. History The peninsula, including all of San Pedro, was the homeland of the Tongva-Gabrieleño Native American people for thousands of years. In other areas of the Los Angeles Basin archeological sites date back 8,000–15,000 years. The Tongva believe they have been here since the beginning of time. Once called the "lords of the ocean", due to their mastery of oceangoing canoes (Ti'ats), many Tongva villages covered the coastline. Their first contact with Europeans was in 1542 with Juan Rodríguez Cabrillo, the Spanish explorer who also was the first to wri ...

Flight Deck
The flight deck of an aircraft carrier is the surface from which its aircraft take off and land, essentially a miniature airfield at sea. On smaller naval ships which do not have aviation as a primary mission, the landing area for helicopters and other VTOL aircraft is also referred to as the flight deck. The official U.S. Navy term for these vessels is "air-capable ships". Flight decks have been in use upon ships since 1910, the American pilot Eugene Ely being the first individual to take off from a warship. Initially consisting of wooden ramps built over the forecastle of capital ships, a number of battlecruisers, including the British and , the American and , and the Japanese Akagi and battleship Kaga, were converted to aircraft carriers during the interwar period. The first aircraft carrier to feature a full-length flight deck, akin to the configuration of the modern vessels, was the converted liner . The armoured flight deck was another innovation pioneered by the Ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bow Thruster
Manoeuvering thruster (bow thruster or stern thruster) is a transversal propulsion device built into, or mounted to, either the bow or stern, of a ship or boat to make it more manoeuvrable. Bow thrusters make docking easier, since they allow the captain to turn the vessel to port or starboard side, without using the main propulsion mechanism which requires some forward motion for turning; The effectiveness of a thruster is curtailed by any forward motion due to the Coandă effect. A stern thruster is of the same principle, fitted at the stern. Large ships might have multiple bow thrusters and stern thrusters. Tunnel thrusters Large vessels usually have one or more tunnel thrusters built into the bow, below the waterline. An impeller in the tunnel can create thrust in either direction that makes the ship turn. Most tunnel thrusters are driven by electric motors, but some are hydraulically powered. These bow thrusters, also known as tunnel thrusters, may allow the ship to doc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Propeller
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gas Turbine
A gas turbine, also called a combustion turbine, is a type of continuous flow internal combustion engine. The main parts common to all gas turbine engines form the power-producing part (known as the gas generator or core) and are, in the direction of flow: * a rotating gas compressor * a combustor * a compressor-driving turbine. Additional components have to be added to the gas generator to suit its application. Common to all is an air inlet but with different configurations to suit the requirements of marine use, land use or flight at speeds varying from stationary to supersonic. A propelling nozzle is added to produce thrust for flight. An extra turbine is added to drive a propeller (turboprop) or ducted fan (turbofan) to reduce fuel consumption (by increasing propulsive efficiency) at subsonic flight speeds. An extra turbine is also required to drive a helicopter rotor or land-vehicle transmission (turboshaft), marine propeller or electrical generator (power turbine). Greater ...

Philippine Navy
The Philippine Navy (PN) ( tgl, Hukbong Dagat ng Pilipinas, , Sea Army of the Philippines) ( es, Armada de Filipinas, , Ejército del Mar de las Filipinas) is the naval warfare service branch of the Armed Forces of the Philippines. It has an estimated strength of 24,500 active service personnel, including the 8,300-strong Philippine Marine Corps. It operates 82 combat vessels, 14 auxiliary vessels, 25 manned aircraft and 8 unmanned aerial vehicles. It shares the responsibility of patrolling the maritime borders with the Philippine Coast Guard, a formerly attached unit which became a separate maritime law enforcement agency in 1998. History Pre-colonial period Before the Spaniards arrived in the Philippines the ancient native people were already engaging in naval warfare, raiding, trade, piracy, travel and communication using various vessels including balangay. A flotilla of balangay was discovered in the late 1970s in Butuan City, Agusan del Norte. Native Philippine warshi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Decommissioning
Ship commissioning is the act or ceremony of placing a ship in active service and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to placing a warship in active duty with its country's military forces. The ceremonies involved are often rooted in centuries-old naval tradition. Ship naming and launching endow a ship hull with her identity, but many milestones remain before she is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and electronic systems, galley, and other equipment required to transform the new hull into an operating and habitable warship are installed and tested. The prospective commanding officer, ship's officers, the petty officers, and seamen who will form the crew report for training and familiarization with their new ship. Before commissioning, the new ship undergoes sea trials to identify any deficiencies needing correct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
