When the An-1250 was slowly towed from the final 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 had a large enough land at the beginning, and the airport was also considering expansion, so it was very empty, but this plane appeared on the airport, giving people the impression that it was a giant ship moving on land.

Because the 130-meter fuselage is too long, the trailer has to make a big circle in order to turn the plane, which is just right for everyone to see.

There are six wheels in two rows in front of it, 13 theoretical dense on one side of the main landing gear, and the largest custom tires are used, but they are still very small in front of the 27-meter-high fuselage.

It's 10 a.m., and the sun has risen, but a large shadow has formed directly in the place where An-1250 is, and the visual impact caused by the large body will make people wonder if they are hallucinations.

The person in charge of the Shu Oak Group was completely shocked and speechless, and it took a long time to dare to believe his eyes:

"Turtle, such a big plane, no wonder the tire service life is only 90 times, such a large aircraft, indeed only this kind of customized special tires can withstand it!"

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 asked Wang Xun directly from the Ministry of Aviation:

"When did you start developing this plane?"

Wang Xun: "I don't know, last year, the engine and the aircraft were approved at the same time. ”

Yang Wei's face was full of disbelief, and he stretched out a finger:

"One year, one year from you! Stand! Item! Arrive! System! Make!

With such a large aircraft, it would take a year to design it! There are also 33-ton aero engines, these projects are at least four or five years, and it will take a year just to test them! ”

Then he pointed to the wingspan of the An-1250, which is nearly 60 meters on one side:

"Such a large wing, not a fatigue test? Don't do the endurance test under harsh conditions? Even the development of wing de-icing pipelines takes seven or eight months, and no matter how much the research and development process is reduced, the test must not be reduced!

Why don't you all do all kinds of tests and just fly up? ”

Wang Xunxin's guess was accurate.

The An-1250 did not go through any test process in the R&D and manufacturing process, that is, it was finished after the Anshang was built.

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

But this must not be said to Yang Wei, Wang Xun thought about it:

"We used a supercomputer to simulate the test, and the test was too time-consuming, and the test was the same when flying, and the cost of the two planes reached 5 billion yuan, and all the materials and processes that exceeded the standard were applied, and there would be no problem.

Moreover, this aircraft was designed by Chief Engineer Anderov, he is a genius, and it is said that he is related to the Antonov family, you see that the layout of the An-1250 is similar to that of the An-225. ”

Yang Wei: ......

What kind of reason is this, what is the meaning of being related to the Antonlov family to build a big plane, then the world has not been messed up early, just talking about China, how many people can be emperors?

However, he also saw that Wang Xun had avoided the topic a little, and he didn't ask any further.

But since the establishment of Xinyuan company, the amazing performance in technology is indeed obvious to all, they have almost no failure, the R&D team works closely, and the boss is 100% assured that the funds are approved casually, and there is really no place to do this.

Speaking of this Wang Xun alone, he also knew that he used to change his fortune 5 in Shifei, but when he arrived in Xinyuan, he became the deputy chief designer of An1250, this gap is a bit exaggerated?

On the runway, the An-1250, which has a composite green background, finally adjusted to the take-off position and prepared to run on the ground.

Ground taxiing is actually a simulated take-off, except that it does not pull up at the end, decelerates and brakes, and the take-off procedure is the same, and it is also a practical test of the aircraft's performance.

The test pilots of the An-1250, two demobilized pilots recruited by Xinyuan from the military, who used to fly the Il-76 and began working as astronaut training and flight school instructors after the transition, then suddenly received a notice last month asking if they would like to be test pilots.

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

Because the fuselage is too high, the cab of the An-1250 is on the top, and they only have to take the internal elevator to get on the plane, and climbing the spare boarding ladder can exhaust people.

Sitting in the eyes of this super monster, the two pilots did not have a very good view, and they had to rely on multiple displays inside the cabin to observe the ground situation through the cameras around them.

Such a large aircraft is supposed to have at least four or five crews, but thanks to the use of the revised SC09 intelligent control system, most of the operations are simplified, and at least one person can fly it, and even fly automatically.

However, in order not to be too shocking, pilots are still available.

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

In the eyes of the people on the ground, the signal lights around the An-1250 lit up one by one, flashing from time to time, and then the eight XW-30 engines began to be turned on one by one for test operation.

When all the engines started, even at very little power, the shrill roar filled the entire airport with noise, and everyone had to put on headphones.

And in the tower, Anderov looked at the An-1250 with pride in his eyes.

The fuel tank of the An-1250 is very exaggerated, if it can reach 700 tons when it is filled, it will take 140 fuel trucks to fill for three days and three nights, and its own weight will be 1090 tons.

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

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

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

That is to say, taking off from Xinyuan, the An-1250 can fly to the South China Sea without stopping when it is fully loaded with fuel, fly around the equator over the Pacific Ocean, fly over the Americas, fly over the Atlantic, fly over Africa, fly over Central Asia, and finally return to Xinyuan Airport.

This is the first miracle aircraft that can fly around the earth without stopping the plane and refueling in the air!

In normal times, in the mission of flying Xinyuan to Qiongzhou, the range is less than 2,000 kilometers, and you only need to fill the An-1250 with 120 tons of fuel, and you can carry the 130-ton H2 space shuttle to run a round trip, but it still takes 12 hours to refuel.

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