Type 032 Midget Submarine
The Type 032 midget submarine and its experimental version Type 032-1 belongs to a family of midget sub developed by the People's Liberation Army Navy (PLAN) in the late 1950s, and it was one of the first submarine indigenously developed in the People's Republic of China (PRC). However, due to the political turmoil in China at the time, Type 032 series was cancelled after only a single unit was completed. Development In the era of Great Leap Forward, PLAN decided to indigenously develop a midget sub for coastal defense, and the midget sub was to adopt the newest hull form, the teardrop hull. Unlike the normal development process where approval is given first before work start, the design begun first and approval was asked and given afterward. Naval Engineer department of the People's Liberation Army Engineering Institute (PLAEI), the predecessor of Harbin Engineering University (HEU) was tasked to design the midget sub. The design team consisted of a team of student led by Profe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Prototype
A prototype is an early sample, model, or release of a product built to test a concept or process. It is a term used in a variety of contexts, including semantics, design, electronics, and Software prototyping, software programming. A prototype is generally used to evaluate a new design to enhance precision by system analysts and users. Prototyping serves to provide specifications for a real, working system rather than a theoretical one. In some design workflow models, creating a prototype (a process sometimes called materialization) is the step between the Formal specification, formalization and the evaluation of an idea. A prototype can also mean a typical example of something such as in the use of the derivation 'prototypical'. This is a useful term in identifying objects, behaviours and concepts which are considered the accepted norm and is analogous with terms such as stereotypes and archetypes. The word ''wikt:prototype, prototype'' derives from the Greek language, Greek ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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] |
Cultural Revolution
The Cultural Revolution, formally known as the Great Proletarian Cultural Revolution, was a sociopolitical movement in the People's Republic of China (PRC) launched by Mao Zedong in 1966, and lasting until his death in 1976. Its stated goal was to preserve Chinese communism by purging remnants of capitalist and traditional elements from Chinese society. The Revolution marked the effective commanding return of Mao –who was still the Chairman of the Chinese Communist Party (CCP)– to the centre of power, after a period of self-abstention and ceding to less radical leadership in the aftermath of the Mao-led Great Leap Forward debacle and the Great Chinese Famine (1959–1961). The Revolution failed to achieve its main goals. Launching the movement in May 1966 with the help of the Cultural Revolution Group, Mao charged that bourgeois elements had infiltrated the government and society with the aim of restoring capitalism. Mao called on young people to "bombard the headqu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frigate
A frigate () is a type of warship. In different eras, the roles and capabilities of ships classified as frigates have varied somewhat. The name frigate in the 17th to early 18th centuries was given to any full-rigged ship built for speed and maneuverability, intended to be used in scouting, escort and patrol roles. The term was applied loosely to ships varying greatly in design. In the second quarter of the 18th century, the 'true frigate' was developed in France. This type of vessel was characterised by possessing only one armed deck, with an unarmed deck below it used for berthing the crew. Late in the 19th century (British and French prototypes were constructed in 1858), armoured frigates were developed as powerful ironclad warships, the term frigate was used because of their single gun deck. Later developments in ironclad ships rendered the frigate designation obsolete and the term fell out of favour. During the Second World War the name 'frigate' was reintroduced to des ...

Soviet M-class Submarine
The M-class submarines, also ''Malyutka'' class (russian: Малютка; ''baby'' or ''little one''), were a class of small, single-, or 1½-hulled submarines built in the Soviet Union and used during World War II. The submarines were built in sections so they could easily be transported by rail. The production was centered in the Gorky Shipyard on the Volga River, after which the sections were transported by railway to Leningrad for assembly and fitting out. This was the first use of welding on Soviet submarines. History 1930s to 1940s Submarines of this class were in four series: VI, VI-bis, XII, XV. The number of VI and VI-bis series boats were almost equal. Series XII was a re-developed project with equivalent tactical characteristics. The first series were powered by one diesel engine and one electric motor. Series XV had developed separately with improved characteristics, including the main ballast in light hull and two shafts. These vessels were mainly used by the Blac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hull Number
Hull number is a serial identification number given to a boat or ship. For the military, a lower number implies an older vessel. For civilian use, the HIN is used to trace the boat's history. The precise usage varies by country and type. United States usage Civilian use For civilian craft manufactured in the United States, the hull number is given to the vessel when it is built and forms part of the hull identification number, which uniquely identifies the vessel and must be permanently affixed to the hull in at least two places. A Hull Identification Number (HIN) is a unique set of 12 characters, similar to the Vehicle Identification Number which is found on automobiles. In 1972, The United States Coast Guard was asked to create a standardized format for HINs to allow for better tracking of accidents and history of boats. This HIN format is as follows: The first three characters consist of the Manufacturers Index Code (MIC) and should only be letters. The following five character ...

People's Liberation Army Navy Submarine Force
The People's Liberation Army Navy Submarine Force (PLANSF) is the submarine service of the People's Liberation Army Navy. It consists of all types of submarines in operational service organized into three fleets: the North Sea Fleet, the East Sea Fleet, and the South Sea Fleet. Submarines have long been one of the three focuses of the People's Liberation Army Navy (the other two are aircraft and major surface combatants), and when the decision was made in late 2006 to concentrate on building other principal surface combatants to strengthen the air defense and to further delay the construction of aircraft carriers due to insufficient air cover, submarines will continue to play the lead dominant role in the assault force for the PLAN. Currently, PLANSF operates a fleet of 66 submarines which include nuclear as well as conventional submarines. Its surface branch counterpart is the People's Liberation Army Navy Surface Force. Nuclear-powered ballistic missile submarines The PLA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Liu Huaqing
Liu Huaqing (; 1 October 1916 – 14 January 2011) was Chinese revolutionary and an admiral of the People's Liberation Army Navy, who served as the third Commander-in-Chief of the Navy from 1982 through 1988. He is considered to have greatly contributed to the modernization of the Chinese Navy, and is hailed as the "father of the modern Chinese Navy" and "father of Chinese aircraft carriers". Biography Taking over the role of Navy Commander-in-Chief from his predecessor Ye Fei (who retired due to health problems), Liu had outlined a three-step process by which China would have a navy of global reach by the second half of the 21st century. In step one, from 2000 to 2010, China would develop a naval force that could operate up to the first island chain. In step two, from 2010 to 2020, China's navy would become a regional force capable of projecting force to the second island chain. In step three, to be achieved by 2040, China would possess a blue-water navy centered around ai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
