人民网北京1月12日电 （芈金 陈云龙）据环球网援引香港媒体报道称，中国首艘国产航母于1月8日上午返回大连造船厂码头，完成了第四次海试任务。军事专家李杰在接受人民网专访时表示，如果工作进程顺利，首艘国产航母正式交付给海军使用指日可待。
报道称，国产航母结束海试返回港口时，飞行甲板上停放着一架歼-15电子战机和一架直-18舰载直升机的等比例模型，分别停放在甲板尾部和舰岛旁。与航母此次出海前的照片对比，可以发现两架模型机的位置均发生了变化，很可能是在海试期间进行了甲板的舰载机系留试验。
军事专家曹卫东在过去接受人民网采访时介绍，飞机模型是要进行一些舰上调度的训练，同时还要借助全比例模型来检验升降机等设备能否正常运行，测试航母究竟可以容纳多少舰载机。
李杰认为，这次海试算是接近后期的海试了，国产航母进行了四次海试，已经发现并解决了很多问题。国产航母进行舰载机上舰的接触、系留这些基本作战动作的试验，表明研发工作已经进入了最后的冲刺阶段，正式交付给海军使用指日可待。
据媒体报道，按照通行做法，航母试航可分为服役前试航和服役后编队试航。服役前试航一般是测试航海性能，例如船体动力、指挥系统、水密舱密封性、雷达导航、通信系统等性能。海试的清单内容非常长，按照一般规律，首次海试的核心是动力系统，第二次海试测试内容依旧集中测试包括动力系统、导航系统、通信系统在内的航行功能，第三次海试是一次针对更多系统、更全面的一次检测，如调度检查等。
自2018年12月27日起，国产航母的第四次海试任务共历时12天时间，这是国产航母首次在黄海和渤海两大海域进行试航任务。
渤海离陆地近水深较浅，海况相对比较平静。黄海水位更深，海浪、水流和海底的状况比渤海更加复杂。李杰表示，“像孩子走路，过去是在家门口蹒跚学步，现在可以走的远一点。这意味着国产航母迈向了新的航海水域阶段，具有里程碑意义。”

No take-off and landing aircraft! My first domestic aircraft carrier returned to the 1st sea trial 1/10

On January 8, Dalian, Liaoning Province, the first domestic aircraft carrier ended its fourth trial flight on the morning of January 8 and returned to the dock of Dalian Shipyard. There were no signs of take-off and landing of the aircraft on the deck. The fourth trial of the domestic aircraft carrier has lasted for 12 days since December 27 last year. This is the first time it has been trialed in the seas of the Yellow Sea and the Bohai Sea. When going to sea and returning to Hong Kong, the carrier deck is equipped with a shipboard model machine and hangs up. Cable. (Source: worm creative)
People's Daily Online, Beijing, January 12 (Zhang Jin, Chen Yunlong) According to the World Wide Web, the Hong Kong media reported that China's first domestic aircraft carrier returned to the Dalian Shipyard Terminal on the morning of January 8, completing the fourth sea trial mission. In an exclusive interview with People's Daily, military expert Li Jie said that if the work process is smooth, the first domestic aircraft carrier will be officially delivered to the Navy for use just around the corner.
According to the report, when the domestic aircraft carrier returned to the port by sea test, an equal scale model of a J-15 electronic warplane and a straight-18 ship-borne helicopter was parked on the flight deck, parked at the tail of the deck and next to the island. Comparing with the photos of the aircraft carrier before going out to sea, it can be found that the positions of the two model machines have changed. It is likely that the deckboard carrier mooring test was carried out during the sea trial.
In an interview with People's Daily in the past, military expert Cao Weidong introduced that the aircraft model is to carry out some training on the ship's dispatch. At the same time, it is necessary to use the full scale model to check whether the elevators and other equipment can operate normally, and test how many carrier aircraft can be accommodated by the aircraft carrier. .
Li Jie believes that this sea trial is close to the late sea trial. The domestic aircraft carrier has carried out four sea trials and has found and solved many problems. The trial of the domestic aircraft carrier to carry out the contact and tethering of the ship on the carrier aircraft indicates that the research and development work has entered the final sprint stage, and the formal delivery to the Navy is just around the corner.
According to media reports, according to the common practice, aircraft carrier trials can be divided into trials before service and after trials. Tests before service are generally tested for maritime performance, such as hull power, command system, watertight tank sealing, radar navigation, communication systems and other performance. The list of sea trials is very long. According to the general law, the core of the first sea trial is the power system. The second sea trial test still focuses on testing the navigation functions including power system, navigation system and communication system. The third sea The test is a more comprehensive test for more systems, such as scheduling checks.
Since December 27, 2018, the fourth sea trial mission of the domestic aircraft carrier lasted for 12 days. This is the first time that the domestic aircraft carrier conducted the sea trial mission in the Yellow Sea and the Bohai Sea.
The Bohai Sea is relatively shallow from the land and the sea conditions are relatively calm. The yellow waters are deeper, and the conditions of the waves, currents and seabed are more complicated than the Bohai Sea. Li Jie said, “Like a child walking, it used to be a toddler at home, and now you can go a little further. This means that the domestic aircraft carrier is moving towards a new maritime waters stage, which is a milestone.”
