Type 027 Torpedo Boat
The Type 027 torpedo boat is a family of Chinese torpedo boats developed to replace Type 025 torpedo boat, and these boats have since retired from active service in the People's Liberation Army Navy The People's Liberation Army Navy (PLAN; ), also known as the People's Navy, Chinese Navy, or PLA Navy, is the maritime service branch of the People's Liberation Army. The PLAN traces its lineage to naval units fighting during the Chinese ... (PLAN). In 1966, PLAN decided to indigenously develop a new generation of large torpedo boat that is armed with four torpedo tubes. The large boat would have better sea keep capability than its smaller predecessors and because it is more heavily armed, less will be needed to achieve the same result in comparison when its smaller predecessors were deployed. Th701st Research Institute of the China Shipbuilding Industry Corporation (CSIC, known as Warship Research Academy at the time) was assigned as the designer, and Wuzhou 449th Factor ...

Type 025 Torpedo Boat
The Type 025 torpedo boat, also known as the Huchuan or Hu Chwan class, was once the backbone of the People's Liberation Army Navy (PLAN) in its confrontations with its much larger opponents in the Republic of China Navy. Although no longer serving in that capacity, this class is still active. While relatively unsophisticated, the class has enjoyed a longevity in active service thanks to a philosophy within PLAN which has continued to favor its use. Powered by Soviet-era engines, the hydrofoil-equipped boats are capable of and carry two torpedo tubes for torpedoes, with some known to be armed with naval mines. Description The Type 025 torpedo boats have a standard displacement of and are at full load. They are long with a beam and a hullborne draft of . The torpedo boats are powered by three Type M 50F diesel engines rated at driving three shafts. Equipped with hydrofoils, they are located forward while the stern planes are located on the surface.

Torpedo Boat
A torpedo boat is a relatively small and fast naval ship designed to carry torpedoes into battle. The first designs were steam-powered craft dedicated to ramming enemy ships with explosive spar torpedoes. Later evolutions launched variants of self-propelled Whitehead torpedoes. These were inshore craft created to counter both the threat of battleships and other slow and heavily armed ships by using speed, agility, and powerful torpedoes, and the overwhelming expense of building a like number of capital ships to counter an enemy's. A swarm of expendable torpedo boats attacking en masse could overwhelm a larger ship's ability to fight them off using its large but cumbersome guns. A fleet of torpedo boats could pose a similar threat to an adversary's capital ships, albeit only in the coastal areas to which their small size and limited fuel load restricted them. The introduction of fast torpedo boats in the late 19th century was a serious concern to the era's naval strategists, i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internal Combustion Engine
An internal combustion engine (ICE or IC engine) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine. The force is typically applied to pistons ( piston engine), turbine blades (gas turbine), a rotor (Wankel engine), or a nozzle ( jet engine). This force moves the component over a distance, transforming chemical energy into kinetic energy which is used to propel, move or power whatever the engine is attached to. This replaced the external combustion engine for applications where the weight or size of an engine was more important. The first commercially successful internal combustion engine was created by Étienne Lenoir around 1860, and the first modern internal combustion engine, known ...

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] |
People's Liberation Army Navy
The People's Liberation Army Navy (PLAN; ), also known as the People's Navy, Chinese Navy, or PLA Navy, is the maritime service branch of the People's Liberation Army. The PLAN traces its lineage to naval units fighting during the Chinese Civil War and was established on 23 April 1949. Throughout the 1950s and early 1960s, the Soviet Union provided assistance to the PLAN in the form of naval advisers and export of equipment and technology. Until the late 1980s, the PLAN was largely a riverine and littoral force (brown-water navy). In the 1990s, following the fall of the Soviet Union and a shift towards a more forward-oriented foreign and security policy, the leaders of the Chinese military were freed from worrying overland border disputes. Traditionally subordinated to the PLA Ground Force, PLAN leaders were now able to advocate for a renewed attention towards the seas. Chinese military officials have outlined plans to operate in the first and second island chains, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
China Shipbuilding Industry Corporation
The China Shipbuilding Industry Corporation (CSIC) was one of the two largest shipbuilding conglomerates in China, the other was the China State Shipbuilding Corporation (CSSC).

Missile Boats
A missile boat or missile cutter is a small, fast warship armed with anti-ship missiles. Being smaller than other warships such as destroyers and frigates, missile boats are popular with nations interested in forming a navy at lower cost. They are similar in concept to the torpedo boats of World War II; in fact, the first missile boats were modified torpedo boats with the torpedo tubes replaced by missile tubes. The doctrine behind the use of missile boats is based on the principle of mobility over defence and firepower. The advent of proper guided missile and electronic countermeasure technologies gave birth to the idea that warships could now be designed to outmaneuver their enemies and conceal themselves while carrying powerful weapons. Previously, increasing the potency of naval artillery required larger projectiles, which required larger and heavier guns, which in turn called for larger ships to carry these guns and their ammunition and absorb their recoil. This trend culm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torpedo Boat Classes
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, and with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially a ''fish''. The term ''torpedo'' originally applied to a variety of devices, most of which would today be called mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large ships without the need of large guns, though some ...
