 Heavy weight! China wants to build a permanent airport in the Antarctic, 28 kilometers away from Zhongshan Railway Station.


It is reported that Chinas 35th Antarctic expedition will take the snow dragon polar expedition ship to Antarctica on November 2, and an important task of the expedition is to build Chinas first permanent airport in the Antarctic ice sheet. At present, the construction of permanent airports in Antarctica has a very large practical demand. The United States, Russia, Britain, Australia and other large countries have permanent airports in Antarctica. The largest airport can even take off and land Airbus A319 aircraft and C-17 strategic transport aircraft.

Chinas first Antarctic permanent Airport

On the 29th, Chinas Science and Technology Daily Wechat published an article entitled Blockbuster! China will build its first permanent airport on the Antarctic ice sheet on the Internet, which has also attracted the attention of foreign media. The thirty-fifth Antarctic expedition team will take the snow dragon to the South Pole in November 2nd, the article said. An important task of this expedition is to build Chinas first permanent Antarctic airport on the ice sheet 28 km from Zhongshan Station in Antarctica.

It is reported that the Snow Eagle 601 aircraft carrying the advance team has arrived at Zhongshan Station in Antarctica before the main force of the Antarctic scientific expedition set sail with the Snow Dragon, which is the fourth time that the Snow Eagle 601 has participated in Chinas Antarctic expedition. As a polar fixed-wing aircraft, Snow Eagle 601 can carry scientific observation equipment and personnel, providing an important guarantee for rapid transportation, emergency rescue and scientific investigation of polar exploration activities. But Snow Eagle 601 had been parked at Russias Antarctic Airport before, and a lot of coordination and communication work needed to be done. To this end, 3 years ago, our thirty-second Antarctic expedition began planning for the construction of a permanent airport on the Antarctic ice sheet. A series of explorations were also carried out. The airport was situated on an ice sheet 28 km from Zhongshan Station. The runway is expected to be 1500 meters long and 80 meters wide.

Yu Jianbin, a reporter from the Peoples Daily, who had been on Chinas 25th Antarctic Science Expedition, told the Global Times on the 29th that most of his teammates set out from Shanghai on the snow dragon when they took the 25th Antarctic Science Expedition. In order to save time, he chose to fly to Port Freemantle in Perth, Australia, to meet the Snow Dragon. It is the main supply point of Snow Dragon in Australia. Then the Snow Dragon crossed the Westerlies to Zhongshan Station on Antarctica, or the Great Wall Station on King George Island. It is not yet possible for all players to fly directly to the Antarctic continent.

Where is the difficulty of building?

So how difficult is it to build a permanent airport on the Antarctic ice sheet? According to the article in science and technology daily, first of all, the location is special, and the alternative location is located on the ice sheet. The ice cover is better than a quilt on the Antarctic continent, but it is moving. To build a permanent airport, we first need to find an area with relatively uniform ice flow and a smaller flow velocity. In order to solve this problem, one year ago, China has carried out a year-long ice flow field observation at alternative locations and a large area of Surveying and mapping by UAV. Secondly, the snow covering several to tens of meters thick on the ice sheet can not meet the requirements of taking off and landing, the snow needs to be transformed. The transformation process is roughly like this: first, the snow is preliminarily treated with a snow shovel and a snow blower, then compacted with a snow compressor, and then supplemented by a snow plow, the snow is turned into a frictional surface. So repeatedly, the difficulty can be imagined.

The planned airport is not a big one, but it does not require a low level of navigation, communications and weather support systems, the article said. For example, in order to solve the problem of meteorological support, three years ago, China has set up automatic meteorological observation stations in alternative locations to accumulate meteorological information.

Cheng Xiao, Dean of the Institute of Global Change and Earth System Science of Beijing Normal University, told the Global Times that the difficulty lies in the location of the airport in Russia, which is the most used by Chinese aircraft, on the flank of a glacier. The velocity and direction of ice flow are relatively regular and cracks are not easy to occur. Secondly, the accumulation rate of snow can not be too large, if the accumulation rate is too large, the runway will need to be often compacted. Foreign countries usually choose to build an airport on blue ice, that is, to build an airport runway on pure ice exposed to the surface. Airport life and runway strength can be guaranteed.

Zhang Xia, director of the Strategic Research Unit of the China Polar Research Center, told the Global Times Wednesday that it was difficult to build an airport in Antarctica because 99.4% of the airports were covered with snow and ice, and the remaining bare areas were few and occupied by the first-mover countries to build their airports. Chinas plan to build the airport is applicable to ordinary aircraft, not to light aircraft that previously could only take off and land with sledges, which would help people move quickly into and out of Antarctica, greatly shorten transportation time and improve the efficiency of scientific research. But this kind of airport runway is very demanding, especially for the ground hardness, Antarctica is covered with ice and snow, hardness is not enough, these need to be overcome.

Whats the usage?

Yu Jianbin said that the construction of permanent airport, generally speaking, means that the scientific research station has a relatively strong strength, become the main distribution center of personnel, materials and even transit station. Australias Casey Station, for example, has a permanent airport, often used as a landing and transit point for flights from other continents. The construction of a permanent airport can meet the needs of larger-scale scientific research projects and international cooperation projects, and also means that scientists can use aircraft to enhance the strength of scientific research.

Zhang Xia holds that the construction of permanent airport has three main meanings: firstly, it can load aerial remote sensing equipment to increase the scope of scientific observation; secondly, it allows large and medium-sized transport aircraft to take off and land, and upgrades the Antarctic investigation and support slow-speed system centered on research vessels to the future rapid system centered on transport aircraft; thirdly, it shortens the scientific research personnel. The exposure time of the crew in the Antarctic field also shortened the time for emergency medical assistance. Cheng Xiao said that the permanent airport is an important step to build air transport and support capacity, there are aircraft now, but to use other peoples airports, the future of Chinas polar aircraft will be able to take off and land at their own permanent airport. However, there is only one polar fixed-wing aircraft in China. With the development of Chinas aviation industry and the construction of Antarctic airport, it is necessary to build a more powerful polar scientific research fleet in the future. u25b2uff08u672cu62a5u7279u7ea6u8bb0u8005?u5f20u4ea6u9a70?u672cu62a5u8bb0u8005?u5218?u626c?u5180u6631u6a35uff09u672cu6587u6765u6e90uff1au73afu7403u65f6u62a5-u73afu7403u7f51u3002 More brilliant, please log on to the world wide web http://www.huanqiu.com editor: Li Xi _NN2587
