I ask you to build tractors, but you build rockets?

When the An-1250 was slowly towed from the assembly hangar to the runway by two tandem trailers, everyone was shocked by this unprecedented giant aircraft.

What is the concept of a wingspan of 136 meters? Fortunately, Xinyuan originally acquired a large enough land, and the airport also considered expansion, so it was very empty. However, when this plane appeared at the airport, it gave people the impression of a giant ship moving on land.

Because the 130-meter aircraft is too long, the trailer had to make a large circle in order to turn the aircraft, which was just enough for everyone to see clearly.

There are six wheels in two rows in the front, and 13 wheels on one side of the main landing gear. They are densely packed with the largest custom-made tires, but they still look extremely small in front of the 27-meter-tall aircraft.

It is now 10 o'clock in the morning, and the sun has risen, but a large shadow is directly formed where An 1250 is located. The visual impact caused by the huge body will make people wonder if they are hallucinating.

The person in charge of Shu Oak Group was completely shocked and speechless. It took him a long time to believe his eyes:

"Gui'er, for such a big plane, no wonder the tire service life is only 90 times. It is true that only this kind of customized special tires can withstand such a big plane!"

Since the empty weight reached 390 tons, the preparation process for the An-1250 was also long, but Yang Wei was not impatient at all. He had too many questions.

He directly asked Wang Xun of the Aviation Department:

"When did you start developing this aircraft?"

Wang Xun: "I'm not sure. Last year, the engine and aircraft projects were approved at the same time."

Yang Wei looked in disbelief and stretched out a finger:

"One year, one year you go from! Establish! Project! to! Make! Make!

For such a big aircraft, even the design would take a year! There are also 33-ton aero engines. These projects take at least four to five years, and the test run alone takes one year! "

Then he pointed to the An-1250’s wingspan of nearly 60 meters on one side:

"With such a large wing, there is no fatigue test? No endurance test under severe aircraft conditions? Even the development of the wing de-icing pipeline will take seven or eight months. No matter how the development process is reduced, the test is absolutely It can’t be reduced!

Don’t you just carry out various tests and just put it on the plane? "

Wang Xundao's guess was really accurate.

There was indeed no testing process during the development and manufacturing process of the An 1250. It was just built and installed.

Why? Because Lin Ju wrote all the design parameters and working conditions into the system research institute in advance during the research and development process, the mission of the system research institute will be successful as long as funds are accelerated, so as long as it is produced according to the obtained technical results, there is no need for verification at all.

But this must not be said to Yang Wei. Wang Xun thought for a while:

"We used supercomputer simulation tests, and the tests were too time-consuming. The same goes for flying tests. Moreover, the cost of each of these two aircraft reached 5 billion. They all used materials and processes that exceeded the standard. There will be no problems. of.

Moreover, this aircraft was designed by Chief Engineer Androv. He is a genius, and it is said that he is related to the Antonov family. You can see that the layout of the An-1250 is similar to that of the An-225. "

Yang Wei:......

What the hell is this reason? Why can you build a big airplane if you are related to the Antonlov family? The world has been in chaos for a long time. How many people in China alone need to be emperor?

However, he also saw that Wang Xun was avoiding the topic and did not pursue the question any further.

However, Xinyuan Company's astonishing technical performance since its establishment is indeed obvious to all. They have almost no failures, the R\u0026D team works closely, and the boss is 100% confident in granting funds to his subordinates at will. There is really no place that can do this.

Speaking of Wang Xun alone, he also knew that he was transferred to Yun 5 in Shifei before, but when he arrived at Xinyuan, he became the deputy chief designer of An 1250. Is this gap a bit exaggerated?

On the runway, the An-1250, which is made of composite materials with a green background, finally adjusted to the take-off position and prepared for ground taxiing.

Ground taxiing is actually a simulated takeoff. Except for not pulling up at the end and decelerating and braking, it is the same as the takeoff procedure. It is also a practical test of the aircraft's performance.

The An-1250 test pilots were two retired pilots recruited by Xinyuan from the military. They had previously flown the Il-76. After their transition, they began to serve as astronaut training and flight school instructors. Then last month they suddenly received a notice asking them if they wanted to fly. Don't want to be a test pilot.

Both of them agreed, and then began to learn the parameters of the aircraft they would test fly. However, until they got on the plane, they still couldn't believe that they were flying such a large aircraft.

Because the aircraft is too high and the driver's cab of the An-1250 is at the top, they have to take the internal elevator to get on the plane. Climbing the spare boarding ladder is exhausting.

Sitting in the eyes of this super behemoth, the two pilots' vision was not very good. They had to rely on multiple displays inside the cabin and observe the ground conditions through the cameras around them.

Such a large aircraft should have a crew of at least four or five, but due to the adoption of the revised SC09 intelligent control system, most operations have been simplified. At least one person can fly it, and it can even fly automatically.

However, in order to avoid being too shocking, pilots were still equipped.

The tower notified the aircraft to self-check and start the engine. The two test pilots quickly turned on various switches in the cabin, applied the brakes, and then waited for the long self-check process.

From the perspective of people on the ground, the signal lights around the An 1250 lit up one by one and flashed from time to time, and then the eight XW-30 engines began to start up and test run one by one.

When all the engines started, even at low power, the high-pitched roar filled the airport with noise and forced everyone to wear headphones.

In the tower, Androv looked at An 1250 with pride in his eyes.

The fuel tank of the An 1250 is very exaggerated. If it is filled up, it can reach 700 tons. It will take 140 fuel trucks to fill it for three days and three nights. By then, it will weigh 1,090 tons.

If it is full of fuel and no load, the XW-3 engine consumes about 3.25 tons of fuel per hour when starting, and cruising after takeoff consumes 2.4 tons. You can turn off the four engines and fly with half thrust, then you can stay in the air for 57 hours, with 840 It flies at a speed of kilometers per hour and has a range of up to 47,800 kilometers.

What is this concept? The circumference of the equator is 40,000 kilometers.

The extra 7,800 kilometers is almost the distance of a transoceanic route.

In other words, taking off from Xinyuan, when empty and full of fuel, the An-1250 can fly to the South China Sea without stopping, fly around the equator, across the Pacific, over the Americas, across the Atlantic, over Africa, over Central Asia, and finally back again. Xinyuan Airport.

This is the first miracle aircraft that can fly around the earth on its own without stopping or refueling in the air!

In normal times, the mission from Xinyuan to Qiongzhou has a range of less than 2,000 kilometers. It only needs to refill the An-1250 with 120 tons of fuel to carry the 130-ton H2 space shuttle back and forth, but it still takes 12 hours. to refill fuel.

Therefore, any aviation person will understand that this will be an unprecedented progress in the human aviation industry!
