Recently, following the "Liaoning ship" and is being painted in China's first domestic aircraft carrier 001A, China's third aircraft carrier to become the focus of foreign media competing hot, and even users to design a third aircraft carrier renderings The
"Model 001A second Chinese aircraft carrier will be completed in 2017, the third is 002 type, completed in 2021, and its displacement will be larger, reaching 85,000 tons." Russia "today's economic news agency" recently said.
"After the transformation of the former Soviet aircraft carrier from the 'Liaoning' aircraft carrier, China's first domestic aircraft carrier built in Dalian is also about to launch." China's third aircraft carrier is also being built in Shanghai. "Japan" Asahi Shimbun "site over the same period Reported.
What is the third carrier? Technology Daily reporter with you to open the third aircraft carrier's head.
It is possible to use conventional steam power
As early as the end of 2016, China National Defense University Professor Jin Yannan has revealed that China's third aircraft carrier --002 aircraft carrier, has been in March 2015 in Jiangnan Changxing Shipyard started construction.
Navy military experts Li Jie accepted the Science and Technology Daily reporter said, 002 type of aircraft carrier, looks and the past is not the same as the Chinese aircraft carrier. He said, 002 type looks more like the United States, rather than the Russian aircraft carrier.
So, China's third aircraft carrier will not be the same as the United States, but also the world's most advanced nuclear power? "Nuclear-powered aircraft carrier technology requirements than conventional power aircraft carrier is much more complex.As the hull scale is limited, not only to the design and development of high-power, compact reactor, and the need to produce high concentration of fuel rods, but also Consider its security. "Li Jie said.
According to reports, compared with a number of reactors, and often can repair and replace the fuel of the ground civilian nuclear power plants, marine reactors for 20 years or so for a material, refueling when the need to remove the entire core from the hull, and this period is not in use. US marine reactor fuel concentration of 93% or more, more than the concentration of weapons, so as to ensure the use of decades of refueling. For example, the US "Enterprise" aircraft carrier equipped with eight reactors, not only take up a lot of space, but also in the use of the process also exposed a lot of problems.
Li Jie said that marine reactors have higher requirements for nuclear safety and sealing measures, because thousands of crew members live and work near the reactor, and in the event of a problem, the disaster is unthinkable. Marine reactors also require high control technology, civil reactors are generally smooth after the start of the operation, if the ship to high-speed navigation or berthing into the port, you need precise control of the core heat.
National Defense Science and Technology University National Security and Military Strategy Research Center military experts Professor Wang Qun also told the Science and Technology Daily reporter, design and manufacture of aircraft carrier nuclear reactor technical requirements are very high, although China has long been able to manufacture nuclear-powered submarines, but the conventional power carrier to nuclear-powered aircraft carrier , Involving a lot of key issues, and can not be achieved overnight.
It can be seen from the perspective of mature technology, the third aircraft carrier design is likely to use conventional steam power.
Is unlikely to use electromagnetic catapult
Last year in June, when the naval commander Wu Shengli for the Chinese Academy of Engineering, ship electromagnetic ejection device research expert Ma Weiming major general umbrella photos on the Internet caused by hot, then some media and observers once that China will be in the third Aircraft carrier on the use of electromagnetic ejection way.
In this regard, Li Jie believes that the development of China's aircraft carrier in some key technologies, although made a major breakthrough, but in order to achieve the degree of engineering and practical, but also a lot of experiments and running; if from a more secure point of view Consider that China's third aircraft carrier may use steam ejection way.
According to public information, China's third aircraft carrier project and electromagnetic catapult project project time roughly the same. For weapons such as aircraft carrier, the maturity of its subsystems must be much greater than the overall design of the time, in order to carry out the overall equipment, especially the key equipment, otherwise completely unable to carry out the overall design, and even comprehensive project feasibility can not be carried out.
One has been engaged in naval equipment research and development work sources said that China's second domestic aircraft carrier is not equipped with the possibility of electromagnetic catapult. If the second domestic aircraft carrier to use electromagnetic catapult, then it means that the overall design of the aircraft carrier from scratch, researchers five or six years of effort will completely overthrow, but also means that China had for the second aircraft carrier The investment in research funds will be completely void, which is obviously unrealistic.
According to Hong Kong, "South China Morning Post" reported on February 13, China's third aircraft carrier will use conventional steam ejection take-off, will be equipped with at least three steam catapult, rather than more advanced electromagnetic catapult. US think tank Jamesston Foundation also wrote that China 002 aircraft carrier will soon be available, it will be the use of steam ejection aircraft carrier.
Not long ago online photos also confirmed the Chinese and foreign media reports. The picture shows the Wuhan-based land-based aircraft carrier model is being rebuilt. This shows that China's next aircraft carrier 002 will be with the second aircraft carrier 001A type, there is a substantial improvement. The most notable is the front of the deck to take off the springboard, which has been demolished on the model, which makes it easier to estimate the installation of the catapult for China's third aircraft carrier.
More than three is the formation of primary combat capability based on protection
In recent years, the Chinese navy has developed rapidly. According to statistics, as of 2016, the total number of Chinese naval vessels more than 300, and more than half are after 2000, new ships, especially as the carrier carrier core ships destroyers and frigates, more than Bacheng are new construction after 2010 The
But if the aircraft carrier in accordance with the current service period of 50 years, then at least the end of this century, the beginning of the next century, the aircraft carrier is still the world's dominance of the sea, is still the national navy, especially the great power of the Navy.
"The future of the Chinese Navy has more than three aircraft carrier is the basis for the formation of primary combat capability to protect a combat, a training, a maintenance, so that once something can guarantee that at least one aircraft carrier can appear in the area, In the major strategic direction of the sea to play a prominent effect. "Li Jie told the Science and Technology Daily reporter.
"In order to safeguard the country 's security and interests, we need to deploy two aircraft carrier battle groups in the important Pacific Ocean, the South China Sea and the Indian Ocean, and we need to deploy five to six aircraft carriers in the future," said Chinese military expert Yin Zhuo.
Li Jie said that China not only in Qingdao, Shandong, there are aircraft carrier port and berth, but also in southern China's Hainan Province, there are aircraft carrier port and berth.
Expert analysis, the main force of modern warfare is the missile and aviation combat power, so China needs to be as far away as possible from the local deployment of combat power, expand combat space. At present, the intended location of the aircraft carrier battle group activities include the United States Navy and so on through the Chinese security is essential to the Pacific Ocean, as well as islands and rock reefs increasing sovereign tension in the South China Sea and as the main maritime logistics routes in the Indian Ocean The
Last year in late December to January this year, Liaoning ship through the first island chain on the Miyagi Strait, for the first time into the Pacific Ocean, held in the South China Sea overseas training. Li Jie said that in the future, the domestic aircraft carrier deployment may be more to the South China Sea as the center to carry out activities.
