General Electric LM2500
The General Electric LM2500 is an industrial and marine gas turbine produced by GE Aviation. The LM2500 is a derivative of the General Electric CF6 aircraft engine. As of 2004, the U.S. Navy and at least 29 other navies had used a total of more than one thousand LM2500/LM2500+ gas turbines to power warships. Other uses include hydrofoils, hovercraft and fast ferries. In 2012, GE developed an FPSO version to serve the oil and gas industry's demand for a lighter, more compact version to generate electricity and drive compressors to send natural gas through pipelines. Design and development The LM2500 was first used on the US Navy in 1969, after the original FT-4 gas turbines experienced many technical problems. Later, they were used in US Navy warships in the of destroyers and the related , which were constructed from 1970. In this configuration it was rated to . This configuration was subsequently used into the 1980s in the s, and s. It was also used by one of People's Rep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aeroderivative 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 ...

Amphibious Assault Ship
An amphibious assault ship is a type of amphibious warfare ship employed to land and support ground forces on enemy territory by an amphibious assault. The design evolved from aircraft carriers converted for use as helicopter carriers (and, as a result, are often mistaken for conventional fixed-wing aircraft carriers). Modern ships support amphibious landing craft, with most designs including a well deck. Coming full circle, some amphibious assault ships also support V/STOL fixed-wing aircraft, now having a secondary role as aircraft carriers. The role of the amphibious assault ship is fundamentally different from that of a standard aircraft carrier: its aviation facilities have the primary role of hosting helicopters to support forces ashore rather than to support strike aircraft. However, some are capable of serving in the sea-control role, embarking aircraft like Harrier or the new F-35B variant of the Lightning II fighters for combat air patrol and helicopters for an ...

Spanish Navy
The Spanish Navy or officially, the Armada, is the maritime branch of the Spanish Armed Forces and one of the oldest active naval forces in the world. The Spanish Navy was responsible for a number of major historic achievements in navigation, the most famous being the discovery of America and the first global circumnavigation by Elcano. For several centuries, it played a crucial logistical role in the expansion and consolidation of the Spanish Empire, and defended a vast trade network across the Atlantic Ocean between the Americas and Europe, and the Manila Galleon across the Pacific Ocean between the Philippines and the Americas. The Spanish Navy was the most powerful maritime force in the world from the late 15th century to the early 18th century. In the early 19th century, with the loss of most of its empire, Spain transitioned to a smaller fleet but maintained a major shipbuilding industry which produced important technical innovations. The Spanish Navy built and operat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Thai Navy
The Royal Thai Navy ( Abrv: RTN, ทร.; th, กองทัพเรือไทย, ) is the naval warfare force of Thailand. Established in 1906, it was modernised by the Admiral Prince Abhakara Kiartiwongse (1880–1923) who is known as the father of the Royal Navy. It has a structure that includes the naval fleet, Royal Thai Marine Corps, and Air and Coastal Defence Command. The RTN headquarters is at Sattahip Naval Base. The navy operates three naval area commands (NAC): Northern Gulf of Thailand (First NAC); Southern Gulf of Thailand (Second NAC); and the Andaman Sea ( Indian Ocean) (Third NAC). RTN also has two air wings and one flying unit on its aircraft carrier.

Aircraft Carrier
An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and facilities for carrying, arming, deploying, and recovering aircraft. Typically, it is the capital ship of a fleet, as it allows a naval force to project air power worldwide without depending on local bases for staging aircraft operations. Carriers have evolved since their inception in the early twentieth century from wooden vessels used to deploy balloons to nuclear-powered warships that carry numerous fighters, strike aircraft, helicopters, and other types of aircraft. While heavier aircraft such as fixed-wing gunships and bombers have been launched from aircraft carriers, these aircraft have not successfully landed on a carrier. By its diplomatic and tactical power, its mobility, its autonomy and the variety of its means, the aircraft carrier is often the centerpiece of modern combat fleets. Tactically or even strategically, it replaced the battleship in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
COGAG
Combined gas turbine and gas turbine (COGAG) is a type of propulsion system for ships using two gas turbines connected to a single propeller shaft. A gearbox and clutches allow either of the turbines to drive the shaft or both of them combined. Using one or two gas turbines has the advantage of having two different power settings. Since the fuel efficiency of a gas turbine is best near its maximum power level, a small gas turbine running at its full power is more efficient compared to a twice as powerful turbine running at half power, allowing more-economical transit at cruise speeds. Compared to combined diesel and gas (CODAG) or combined diesel or gas (CODOG), COGAG systems have a smaller footprint but a much lower fuel efficiency at cruise speed and for CODAG systems it is also somewhat lower for high speed dashes.

Combined Diesel Or Gas
Combined diesel or gas (CODOG) is a type of propulsion system for ships that need a maximum speed that is considerably faster than their cruise speed, particularly warships like modern frigates or corvettes. For every propeller shaft there is one diesel engine for cruising speed and one geared gas turbine for high speed dashes. Both are connected to the shaft with clutches; only one system is driving the ship, in contrast to CODAG systems that can use the combined power output of both. The advantage of CODOG is a simpler gearing compared to CODAG, but it needs either more powerful or additional gas turbines to achieve the same maximum power output. The disadvantage of CODOG is that the fuel consumption at high speed is poor compared to CODAG. CODOG vessels * MGB 2009, a modified Motor Gun Boat of the Royal Navy (1947), and *The two German torpedo boats ''Pfeil'' and ''Strahl'' (''Vosper'' class, 1963-65) *The US Navy s (built 1966-1971) *The US Coast Guard s (from 1967) * ...
