 How to predict the sea trial of domestic aircraft carrier? Just look at the 4 items


Caption: more than 23 tugs surrounded domestic aircraft carriers, causing widespread speculation. In fact, it is important to judge whether the domestic aircraft carrier is officially out of the sea. It can be concerned about the following points: whether the ships boarding bridge next to the carrier is evacuated, whether the boiler fires smoke or not, as well as the changes in the banner of the surrounding banners. In addition, the factors of the sea test of the carrier also include weather and sea conditions, which is also a point to be concerned. [global military reports Global Times reporter Guo Yuandan] yesterday (April 23rd) was the 69th anniversary anniversary of the founding of the peoples navy, which was called the Navy Festival by the patriotic army. There was a rumor that the domestic aircraft carrier of the sea trial would be moved on this day. The Global Times reporter noted that this was the first body movement of the domestic aircraft carrier after launching in April 26, 2017. However, it did not sail to the open sea as expected, but returned to berths. But it is clear that the first voyage of domestic aircraft carrier has entered countdown. The false alarm of the homemade aircraft carrier On the morning of April 23rd, when the tugboat approached the homemade carrier of the Dalian shipyard, the local army fan told the Global Times reporter that the tug was in place, and the sea test was to be carried out today. Then the news on the Internet is constantly updated: a lot of tugboats are pushed and pushed around the carrier on the deck of the aircraft carrier, a crane continues to go up and down the trawler shifts back and forth. During this period, there are firecrackers and whistles, the tug was once far away, and then all came back to the top. But in the end, it was still a false alarm. The domestic aircraft carriers basically did not leave berths. However, the news from Chinas Internet has aroused great concern from the international public opinion. Lianhe Zaobao, Singapore, reported the incident with the official sea trial and the first Chinese aircraft carrier leaving the port early this morning. Reuters also quoted the network news that Chinas first homemade aircraft carrier plans to leave Dalian wharf for sea trials, the 23 day the Chinese navy was set up 69th anniversary commemorative days. However, the report also noted that there were many reports on Chinas online sea trial on domestic carriers, but few official reports reported that the Chinese Ministry of defense did not comment on the matter. Hongkongs South China Morning Post, quoted by the Navy, said the homemade aircraft carrier will have a sea trial this week. If weather and sea conditions permit, it is likely to be on Monday. The domestic aircraft carrier has a greater challenge for the first time in the sea The outside world has speculated that the first domestic aircraft carrier will start its first sea trial on the 23 day. April 23rd is the 69th anniversary anniversary of the establishment of the Navy. According to the past practice, this is the day of giving gifts. In addition, the Liaoning maritime bureau website issued three navigation warnings in April 20th, which is also considered to be related to the first voyage of the domestic aircraft carrier. A series of construction details also seem to support the conclusion that aircraft deck has been emptied, scaffolds have been removed, and sea trial supplies have been lifted onto the deck. From April 26, 2017 to now, it has been over a year, Li Jie 23, the aircraft carrier expert told the Global Times reporter that the outfitting time of one year was enough to solve the main technical problems, and the various system tests should have been completed, so the recent domestic aircraft carrier went out to sea test completely without problems. However, whether the military mission mentioned in the three navigational warnings issued by the marine bureau is related to the sea trial of the aircraft carrier is not exactly the answer. Because military missions have a wide range of meanings, submarine activities, navigation replenishment and so on can be counted, and aircraft carrier trial can only be one of them. When the world Times reporter consulted the first sea trial of the Liaoning ship in August 10, 2011, the maritime department issued a warning only one day in advance, and made it clear that the Dalian Port OC3000-2# ship went to sea for the sea trial from 0 to 14 in August 10th, and the other ships were prohibited from entering the specific sea area of the Liaoning Bay of northern the Yellow Sea. Li Jie believes that the biggest difference between the domestic aircraft carrier and the first sea trial of the Liaoning ship is that the Liaoning ships predecessor Varyag is floating across the sea to China, and a lot of performance has been tested by practice. The domestic aircraft carrier is Chinas independent design. The ships engine, hull seal, construction technology, welding technology are all first tested, and the challenge is more challenging. The requirements of ship outfitting and sea trial are different, such as different water depth, different underwater pressure, different pressure under the joint, and different sea water salinity, which are new challenges for domestic carrier. What the hell did you do? What did the homemade aircraft carrier do on the 23 day? Experts believe that when the domestic aircraft can go to sea, and the 23 day of the test has a huge relationship. The field photos show that the crane is moving on the carrier deck, which may be a small range activity around the original berth with the assistance of the tugboat, which belongs to the ship tilt test. This is one of the preparatory actions that must be carried out before going to sea trial, which is related to the safety of ships. Li Jie believes that the 23 day is the warm-up of the aircraft carrier before the sea. Before the official trial, the basic elements should be tested, including the balance of the configuration, the leakage of the hull after the tilt, and the strength of the other parts. Li Jie believes that if the new problems appear in the warm-up process, we need to debug, which is a process that must be passed. Li Jie said that the factors affecting the sea trial include the objective conditions such as meteorology and sea conditions. Another notable detail was that, in the scene, the landing bridge was not evacuated by the carrier, which Li Jie thought meant that the carrier did not intend to carry out the sea test immediately, but to prepare for the possible problems in the tilt test. In addition, a professional who asked for anonymity on 23 days told the Global Times reporter that the ship has a preparation process, one of the necessary preparations is the boiler ignition, in appearance, the chimney will appear smoke. If there is no preparatory work for the relevant power trial, the possibility of trial sailing is basically ruled out. 23 days of activities, the domestic aircraft carrier did not appear relevant signs. And during the trial period, there will always be a tug alongside the carrier.
