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

An 1250 lowered its nose, and the front wheel bottomed out just a little later than the main landing gear. Then the eight engines turned on reverse thrust at the same time and braked with full force.

This still weighs only 440 when empty. If it is to carry an H2 space shuttle or the three core-stage rocket bodies of Xinyuan-2A, the weight will be close to 700 tons. Every time it lands, it must actively decelerate with all its strength.

Since the landing was on runway 2, the An-1250 was far away from everyone. Finally, when it passed the end of the runway, two fire trucks sprayed water from both sides to create a water curtain. Normally, the aircraft would pass under the water curtain.

However, the huge size of the An-1250 can only make the water curtain slightly pass the nose of the aircraft. This is only possible when the firefighters have adjusted the height of the water gun to the limit.

The super beast relied on its own power to round a big bend and return to Runway No. 1. It slowly advanced in the opposite direction from takeoff and finally stopped in front of the crowd.

Everyone immediately made way for a passage, and the superior leaders strode forward accompanied by Lin Ju. At this time, a hatch opened on the side of the nose of the aircraft. When they walked in, two test pilots just got off the elevator. Stand at the hatch and salute.

The superior shook hands with both of them and asked cordially:

"Is it difficult to fly such a big plane?"

"Reporting to the leader, the An1250 adopts an advanced intelligent assisted driving system. The entire machine is controlled by an electronic system. It is very easy to drive. It also has the ability for AI to take over and fully autonomous driving in emergency situations."

The superior nodded, and then followed Xinyuan's engineers to walk along the side of the aircraft to the cargo hold at the rear.

When passing by the main landing gear with 13 wheels, the superior couldn't help but touch the hard tires.

"This tire must be very expensive, right?"

The person in charge of Shu Oak Company quickly rushed over:

"The tires required for the An 1250 are of very high standards. We teamed up with Xinyuan Company to develop new technologies and form a new team to produce them. The production cost is not too high, but the investment in R\u0026D alone has reached more than 100 million, which is a breakthrough introduced many new technologies.”

Superior: "Very good. The tires of this aircraft have led to a major enterprise project, and the entire aircraft can lead to the technological upgrading of the entire industry chain."

Then the group of people arrived at the cargo hold. The hatches on the left, right and below had been opened, revealing a tall cargo hold that looked like an abyss.

The height above the ground alone is nearly three meters. When more than a dozen people walked in along the tailgate, it was hard to believe their eyes.

The cargo hold of the An 1250 is 7.5 meters wide and 6.9 meters high. It is spacious enough to park two heavy trucks side by side, and the length is also a terrifying 100 meters. The group walked in the cargo hold for a long time before reaching the cockpit.

A middle-aged man in casual clothes but unable to hide his sharp aura touched the inner wall of the cargo hold and said with emotion:

"This aircraft has two 99A main battle tanks parked side by side. It can put down six tanks. It can fly two platoons on the plateau front line. If it is to transport people, it can be modified to carry a brigade of seven or eight thousand people, and there will be no problem!"

As he spoke, he looked at Tao Changhong, who was also touching around, and the latter pretended not to notice and turned his head.

The maximum load capacity of the Y-20 is 66 tons, which is just enough to fit a 99A. Isn’t the An-1250 capable of carrying at least six Y-20s?

But if the military is told to exchange six Y-20s for one An-1250, they will definitely agree, because strategic airlift capabilities are not just a matter of adding a few more aircraft together, but the ability to be dropped at one time.

Moreover, the purchase price of one Y-20 is 800 million, and 6 is 4.8 billion, which is about the same price as one An-1250. Obviously the latter is better, and having two or three of them is reassuring.

Moreover, this kind of priceless super aircraft is actually made in China. The middle-aged man's heart is surging at the moment, and he is already thinking about how many aircraft to buy and where to put them in the Western Military Region, which needs air transport capacity the most.

There were not many people in the cockpit. Apart from the superiors and other leaders, there were no more than six people. They were amazed by the experience of taking the elevator to the cockpit. Moreover, when the four or five people from Xinyuan entered the cockpit, it was not crowded at all. The superiors He also sat in the driver's seat and had voice interaction with SC09. The surprise in his eyes could not be hidden.

"Will future C832 and C822 be equipped with this kind of intelligent driving system?"

Lin Ju: "Yes, our SC09 intelligent driving system was originally developed for the space shuttle. Later, it was simplified and derived into a flight version. It is very reliable and can also alleviate the driver's fatigue problem during flight. It pays great attention to man-machine. Interaction.”

At noon, the superior postponed his schedule and had lunch in the canteen of Xinyuan Company while observing the working status of the employees in the B-level base.

He found that although it was extremely busy here, the atmosphere was still very relaxed, and there was no clear distinction between superiors and subordinates in the department. Maybe it was because Lin Ju took the lead. All the management and most ordinary employees ate in the cafeteria, and they had become accustomed to it over a long period of time.

After lunch, the superiors, space agency bosses and others saw Androv's planned "Forward" space station in the small conference room.

The superiors were moved, the boss was dumbfounded, and the others were also surprised.

This is a space station with an estimated mass of two thousand tons during operation! Still centrifugal!

Androv: “This year we will launch two core modules, and then launch six spoke modules up and install them on the H2 large space shuttle. They will increase the strength by fixing the trusses on the outside, and then continue to launch the crew module.

As for the six service modules and six crew modules, it may take until next year to complete the launch, and the Forward space station will also be put into trial operation before 2018. "

Boss: "With so many things, we have to launch heavy or giant rockets at least twenty or thirty times."

Lin Ju: "So it is necessary to install 1250."

But this is not over yet, Androv continued to add:

"The maximum angular speed that the human body can rotate in normal life is only 2 revolutions per minute, so the Forward is just the beginning, or a verification type. The future centrifugal space station will provide a gravity of about 0.6G and the rotation speed will be reduced to 1.5 revolutions per minute. , with a radius of about 240 meters, so that it can support several years of space life and prepare for entering deep space."

Academician She, who came with the boss, thought for a long time. After listening to Androv's words, his thoughts immediately opened up:

"You are already planning a deep space voyage?!"

Androv nodded: "If a nuclear thermal engine is used to travel to Mars, the round trip can be shortened to 4 to 6 months. But if it goes further, Jupiter, Saturn, even to the Kuiper Belt, and even interstellar travel, in Without gravity devices or sublight-speed spacecraft that directly act on the principle of gravity, centrifugal space stations are our only means of maintaining gravity.

Of course, these are still far away from now, but it is necessary to prepare early. Moreover, the Advance can also serve as the prototype of a space port, providing mankind with an epoch-making permanent space port, so that astronauts no longer need to work long hours every day. Exercise ensures physical function, and the time saved is valuable in space. "

Deep space navigation may be just an idea for other people on the earth. Even if it is pushed to the next century, it will be no problem. However, Lin Ju believes that the system's mission will only become more and more difficult, from manned spaceflight to manned landing. The span of a month is already quite long.

If he directly came to build a Jupiter scientific research station in the future, he would be really dumbfounded.
