On the morning of May 13, after completion, it will be the largest airport in the world, and the first Daxing International Airport in Beijing, which was ranked as the “Seven Wonders of the New World” by the British “Guardian”, will conduct a real test flight for the first time. China Southern Airlines, China Eastern Airlines, Air China and Xiamen Airlines sent their own models A380, A350-900, B747-8, B787-9 and so on.
This is the first time that a test flight was conducted with a real machine after a successful award landing on January 22, 2019.

The test flight is of great significance to the opening of the airport. After the official approval, the Daxing Airport will be able to sail smoothly.
So, what are the characteristics of the flight test aircraft, and what are the amazing black technologies behind Daxing Airport? Come and see it together!
What are the passenger planes for this test flight?
The China Southern Airlines A380, China Eastern Airlines A350-900, Air China Boeing 747-8 and Xiamen Airlines Boeing 787-9 passenger aircraft participated in the Beijing Daxing Airport test flight, which are the models of various airlines.
Because there are differences in the models of the aircraft that take off and land, the models sent by the four airlines represent different take-off weights and wingspan models.
The Boeing 787-9 passenger aircraft has a maximum takeoff weight of 247 tons and a wingspan of 60 meters.

China Southern Airlines A-380 is currently the world’s largest passenger aircraft, with a maximum takeoff weight of 575 tons, a wingspan of 79 meters, and a take-off distance of 2,900 meters.

China Eastern Airlines A350-900 has a maximum takeoff weight of 268 tons, which is heavier than the Boeing 787-9 and a wingspan of 64 meters.

Air China’s Boeing 747-8 has a maximum takeoff weight of 439 tons and a wingspan of 68 meters.

These four passenger aircraft represent different tonnages and are also common types of domestic airlines.
How big is Daxing Airport?
Daxing Airport is located on the south central axis of Beijing. It is basically the same distance to Beijing, Xiong’an and Tianjin. It belongs to a super-large international aviation hub between Daxing District of Beijing and Langfang City of Hebei Province. All of them will become the largest in the world. Airport port.

There are 7 runways planned and designed in the airport. It is estimated that by 2040, the passenger flow will reach 100 million passengers, the aircraft will take off 800,000 flights, and the terminal area will reach 1.4 million square meters.
By 2050, the airport will fully construct all reserved control land. It is estimated that passenger throughput will reach 130 million passengers, aircraft take-off and landing will be 1.03 million, and the number of runways will reach 9.
Civil aviation usually uses numbers plus letters to indicate the flight zone level of the runway.
The letters are determined according to the maximum aircraft span and the main wheel outer wheel spacing using the flight zone, from A to F, the highest level is F; the number is determined from the base flight length of the largest aircraft using the flight zone, from 1 to 4, The highest level is 4, and Daxing International Airport is the highest rated 4F airport.
What is the construction scale of Daxing Airport?
In order to achieve ultra-large-scale personnel and aircraft throughput, Daxing Airport has adopted a radial hexagonal layout. Thefive corridors have 82 boarding gates. Passengers walk from the center of the terminal to any boarding gate for no more than 8 hours. minute.
1. Theroof of the airport adopts irregular steel structure with atotal projectedarea of 360,000 square meters, a maximum diameter of more than 1.1 kilometers, and an seismic fortification intensity of 8 degrees. It is also the world’s largest single-isolated building.

2. In order to achieve super strong isolation, the entire terminal building uses1,320 sets of isolation devices, each with a diameter ranging from 1200 mm to 1500 mm, and more than 100 viscous dampers.
Assuming an earthquake, the first thing to ensure is that the terminal structure is intact, and the second is to ensure that the equipment and other instruments are operating normally.

3. Below the airport, there is a high-speed rail tunnel, which is also theworld’s first high-speed rail under the terminal building. By then, passengers can take the high-speed train to reach the terminal.

4. The roof of the terminal building isa 180,000 square meter full roof structure. A total of 12,800 pieces of glass are used toform a free-form roof.
Among them,no two of the 8,000 roof glass are the same, so engineers need to accurately locate the three-dimensional coordinates of each glass.
What black technologies are used in Daxing Airport?
In addition to the large scale of the overall structure of the terminal building and the difficulty of construction, the facilities in the terminal building also have many black technology. such as:
1. The robot receptionist with certain intelligent technology can provide passengers with flight consultation and other services.
2. The automatic returning system of the tray can automate the security inspection process. The security inspection scanner can scan the luggage of multiple passengers, which is twice as fast as the previous security inspection.
According to the design,the system can process about 30,000 pieces of baggage per hour, and can track the position of the baggage all thetime, which will greatly ease the pressure on Beijing passengers.

The construction of Daxing Airport reflects China’s massive black technology in the field of infrastructure construction, which is one of the miracles of modern architecture.
