Exposed on the network of so-called "first domestic carrier installed flight deck" photos. This picture from the network
March 25, 2016, in CCTV international channel today concern column in the, for a group network Shang exposure out of so-called "first ship domestic carrier has laying flight deck" of photos, famous Navy equipment experts, and Navy senior Cao Weidong said: "in accordance with tablets view, China new a ship domestic carrier of deck has laying completed, description hull basic built completed, away from water of days on not is far has. "
Limited steam turbines
Electromagnetic catapult required strong power protection, especially when the ejection of instantaneous high voltage power supply, which is offered by Chinese carriers to existing power systems.
"Admiral kuziniezuofuhaijun" 4 TB-12 steam turbine and 8 pressurized boiler. TB-12, formerly known as TB-8, and TB-8 is made the type 051 destroyer hosts domestic model 453-steam turbine. TB-8 36,000 horsepower is the power, when the type 051 destroyer with 2 TB-8 steam turbine speed of 38 knots. TB-12 's power increased to 45,000 horsepower. In addition, China imported GTZA-674 steam turbine installed on destroyer TB-12 improved.
From TB-8 to TB-12 to GTZA-674, on this series of steam turbines in China has accumulated a wealth of technology, operation and maintenance experience. If used steam turbines for its localization on the Liaoning province-level model, I believe that can at least reach the level of GTZA-674, 4 steam turbine of total power output of about 200,000 HP. The power system without a catapult of Liaoning province-level high speed no problem, but if you are using electromagnetic launch new aircraft carrier was a bit stretched.
United States "Ford", carrier only 4 Department electromagnetic ejection device while charging on needed about 22,000 horse horsepower, if next generation domestic carrier installation 3 Taiwan also power of electromagnetic ejection device, by needed power that over 16,000 horse horsepower, consider to steam turbine in power process in the 50% around of energy loss, only 3 Taiwan ejection device maximum by needed power on accounted for to has full ship total power of about 16%, this must will serious effect carrier speed and other electricity equipment of using.
More need to guard against is, whether it is "Admiral kuziniezuofuhaijun", was India's "weikelamadiya", its installation of TB-12 steam turbine and auxiliary boiler use multiple times during a major accident. Russia has rich experience in the development and use of marine steam turbine like this, TB-12 made in China based on the first generation of large marine steam turbine reliability will continue to be further tested.
"Nuclear power" to promote the dream and the reality
France "Charles de Gaulle" nuclear-powered aircraft carrier.
There is no doubt that using electromagnetic catapult aircraft carrier's best power will surely be like "Ford"-class nuclear-powered + all-electric propulsion system.
Nuclear power can provide inexhaustible energy to catapult and all-electric propulsion system, eliminating the need for mechanical transmission, after the reactor's power into electricity directly to catapult, propeller propulsion motors, and other terminals and carriers on the grid, arranged without large drive mechanism is inside the carrier structure design, handling and maintenance is convenient.
Of course, different from what many people imagine, all-electric propulsion systems for energy conversion efficiency is far better than the mechanical transmission, so infinite nuclear reactors and energy partner, is clearly the most appropriate.
Has just launched the United States Ford-class aircraft carrier ship "Ford" (CVN-78).
But in reality, the next generation of Chinese-made aircraft carrier "nuclear" power is unlikely.
China currently has no readily available high performance pressurized water reactors for use by carriers, 094-type strategic nuclear submarine of the new reactors is rumored performance good, but we should not forget that the boat with marine reactors modified risk.
United States nuclear aircraft carriers and nuclear submarines never shared any of the reactors. France has world Shang most top of nuclear technology, in built "Charles de Gaulle", Shi assumed to directly will triumph level strategy nuclear submarines Shang of reactor with in "Charles de Gaulle", Shang, this sets K15 natural cycle integration pressure water heap technology very advanced, in triumph level Shang of performance also is excellent, but loaded in "Charles de Gaulle", Shang is acclimatized, led to "Charles de Gaulle", duration drag long, added loaded pressure class died heavy Hou only barely input using, but also is in sea try and the follow-up served process in the times exposed problem. Knight Island after listening to the Secretary
Ford-class carrier of electromagnetic catapult.
Of course, if the next generation domestic carriers still using conventional power, does not select only steam catapults. Traditionally, the displacement of more than 30,000 tons of large surface ships were steam turbines as a main power system, a displacement of 20,000 tons of ships more diesel engines and gas turbines. Advantages of diesel engines is fuel efficient, economical; gas turbines are low noise, small vibration, compact structure, fast response, can be more effective in avoiding underwater threats. Large marine gas turbine developed very fast in recent years, with natural circulation ability of highly efficient gas turbines have come out. Displacement and a considerable level in Liaoning province of the United Kingdom, "Queen Elizabeth" aircraft carrier has already broken gas turbines not equipped area for large carriers.
China was from the United States introduced the famous LM-2500 marine gas turbine, also from Ukraine to introduce the DN-80 marine gas turbine. According to foreign media reports, China is now capable of producing DN-80 improved, according to Wu publicly available its output power is about 40,000 horsepower. If the next generation domestic carrier fitted with electromagnetic catapults, sufficient power-reserve needs at least 240,000 horsepower, which requires 4 single power gas turbines up to 60,000 horsepower--is very difficult, but not impossible. "Queen Elizabeth" the MT30 gas turbine on the maximum output power up to 55,000 HP, if the next 10 years to develop its current level MT30 gas turbines, and further improving the conversion efficiency of, the next generation of domestic carrier TRANS 4 gas turbines are not impossible.
Double construction base
MT30 gas turbines.
After the first domestic carrier to determine constructed in Dalian, the second generation of domestic carrier born where became a popular topic.
Dalian shipbuilding heavy industries (Dalian shipyard for short) was founded in 1898, has experienced Russian construction rule, Japan expanded invasion, Soviet liberation took over, Sino-Soviet joint ventures in different periods. Since the founding of the Dalian shipyard has built a total of 44 models, 820 boats, is the largest building ships for the Navy shipyard. China gunboats, the first missile submarines, the first guided-missile destroyer, the first oil supply ships were built by the factory, known as the "cradle of China's Navy".
Shanghai Jiangnan shipbuilding Group (referred to as Jiangnan shipyard, Shanghai shipyard or), formerly known as Jiangnan manufacturing Bureau, founded in 1865, is the Westernization movement in the late Qing earliest and biggest modern industrial enterprises, has created the first rifle, the first steel gun, the first million-ton hydraulic press, the first generation space tracking ship ... ...
A 7-MW gas turbine developed by China for 726-type air cushion landing craft.
Jiangnan Changxing shipbuilding base, built in 2005, on June 3, 2008, from Huangpu shipyard moved to Shanghai Chongming, Changxing island is located in the South-Eastern part of the new home. Changxing Island shipbuilding Base covers an area of 560 hectares, 3.8 km coastline shipbuilding base in accordance with the "100 years behind" requirements planning, divided into 3 lines, and 4 large dock and slipway with track a number of indoor and outdoor. Among them, the largest dock is 580 meters long, 120 meters wide, an area the equivalent of 10 standard football field. In addition is also equipped with more than 7 600-ton gantry crane, a total investment of about 16 billion yuan, it is the largest and most advanced, the most internationally competitive shipbuilding base, annual production capacity of 4.5 million tons, second only to Korea Ulsan shipbuilding yards, second highest in the world.
Official information is not difficult to see from the above, Shanghai Jiangnan shipbuilding group and Dalian shipbuilding industry group with an extremely strong army civilian shipbuilding capacity. But in contrast, Dalian shipbuilding heavy industry focusing on military tasks, and closer long-term cooperation with the military tradition. If there is competition on construction projects in Shanghai and Dalian, Dalian "Liaoning", settled in the moment of advantage. Through the system of China's first aircraft carrier, Dalian shipyard in aircraft carrier hull structures, materials technology and complete outfitting, shore and sea tests, project management and related personnel have been the accumulation of more profound, and become China's only aircraft carrier currently under construction experience in shipbuilding enterprise.
Worth note of is, can built modern carrier of shipyard in world numbered, even is like United States such of carrier superpower, active of 10 ship Nepal meters is hereby level and is built of "Ford", also are from Newport News shipyard a Home; France post-war built of 3 ship carrier (not is helicopter carrier) in the of two ship--"Charles de Gaulle", and "Clermont shuttle", are in Brest Navy shipyard built, addition a ship "Fu Foch", although in shengnaze, Atlantic shipyard starts, Finally was towed to Brest to completion.
United Kingdom "Queen Elizabeth" class using the MT30 gas turbine power 36 MW.
Russia's carrier is more embarrassing, in the heyday of the Soviet Union only in Ukraine within the Nikolayev shipyards able to build aircraft carriers, which led to Russia actually lost the aircraft carrier built after the establishment of the new State. And similar to the Dalian shipyard, Russia through India "weikelamadiya" aircraft carrier conversion works, St Petersburg North mechanical construction of the shipyard into a new base. But the twists of the project proved that building with a construction capacity of large shipyards in difficulty how hard it is.
Place the first indigenously-built in Dalian, off-the-shelf technology and can take full advantage of shipyard experience, risk-averse as possible and easier to control on construction time and cost. If the work undertaken by Shanghai, overseas experience has shown that shortly a new carrier shipyard difficulty with relevant inputs is extremely high. Changxing Island shipbuilding base despite the large-scale, technologically advanced, but that doesn't mean you can have construction skills in the short term (which can be partly responsible for the cabin). It's like Korea Hyundai Ulsan shipbuilding base is the world's largest shipbuilding base, but not aircraft carriers.
Therefore, the Jiangnan shipyard to build only carrier hopes upon domestic next-generation aircraft carrier. As early as in 2011, Shanghai Oriental TV broadcast of the look East programme, South Daqing, General Manager of the Jiangnan shipyard group, declared: "from our facilities, our production capacity, we have met a variety of contractor for the Navy what it needs water on the launching of naval ships include the strategic projects. Now, we are very concerned about the aircraft carrier project, I told you today is: Jiangnan shipyard for the construction of an aircraft carrier ready, it has had the capacity, we hope that the construction of the first of our own design, with independent intellectual property rights of the carrier. "
"The first US aircraft carrier design, with independent intellectual property rights. "South unveiled an answer maybe 5 years ago.
