On March 28, the space exchange meeting organized by the Aviation Development Commission opened again in Beijing.

The day before, the Queqiao relay satellite was put into orbit.

This satellite Xinyuan took over the power part, and installed a 1N "large" thrust Hall thruster with quite good performance, so that it can slow down into orbit with very little fuel consumption, and can adjust the orbit by itself, which is very useful.

On the first day of arrival, it sent back an ultra-high-definition image of the lunar surface, and the Aviation Development Commission selected the best one as the publicity and background picture of the conference.

This time, Xinyuan Company did not send any more heavyweights, and the PPT was almost the same as before, and NAPE was still confidential.

So the limelight is all on the space agency, especially the Long March 10 of the First Academy and the YF130 of the Sixth Academy.

Long March 10 is a giant rocket with a low earth orbit of more than 100 tons and a take-off thrust of more than 5,000 tons.

There were some minor problems in the joint test of the turbine pump and gas generator of the Sixth Academy, but it was not fatal, so the prototype in April was still produced, and it was mass-produced as soon as the test was successful.

This efficiency is 10 times faster than in the past, which is not an exaggeration.

Spending a little money to do big things is based on a long schedule, and now it is spending a lot of money to do big things, the funds are unprecedentedly abundant, and the scientific research team is also quite powerful.

It was only at the end of the exchange meeting, April 1, April Fool's Day, that a message came from the Qiongzhou launch site.

The Xinyuan launch site will be slightly modified to accommodate rockets up to 18 meters in diameter.

In addition, several launch stations in Qiongzhou have also undergone minor adjustments, mainly in terms of operation.

The Xinyuan-2 A, which has been advertised for a long time, is about to be ready for launch.

Three 6-meter-diameter core stages are connected in parallel, with a maximum length of 18 meters, but there is no need to build a new tower.

Both the Wenchang Launch Center and the Xinyuan Launch Center are vertically transferred, and the active launch can accommodate a rocket with a width of 18 meters, but it has to be diagonally in the direction of the diagonal, and 18 meters is just touching the limit.

Therefore, when Xinyuan-2A is launched, it has to be sideways by 45 degrees, and people have to change the angle to see its broad side.

Although the low-earth orbit capacity of the Long March 10 has reached 120 tons, the load factor of Xinyuan-2 is very high, and the recovery is 135 tons, which is very exaggerated.

However, the take-off thrust is still the first in the Long March 10, although this is not a particularly boastful thing.

But compared to Xinyuan No. 2 A and Xinyuan No. 3, there is another thing that will bring greater shock to the world.

On April 3, the "Tianhe" core cabin jointly manufactured by the Fifth Academy and Xinyuan Company left the factory, and while loading the Il-76 and preparing to transport it away, the experts of the Fifth Academy saw a super-large nose that had never been seen before stretched out from the tall hangar not far away.

They asked what it was, and then they saw the person in charge of the aviation department of Xinyuan and said indifferently:

"That, we built a big plane to transport rockets, it's too long, the assembly must stretch out a part of it, no way 130 meters is indeed a bit long?"

Five Hospitals: !

Also on the same day, the An-1250 was officially registered with the Civil Aviation Authority, and the two aircraft were numbered B-4043 and B-4143 respectively.

The beginning of B is in accordance with international standards, all civil aviation aircraft start with B, and 4 represents a military aircraft, registered in the Air Force.

"0" and "1" represent the first and second An-1250, and 43 represents the registration date of April 3.

If it is an ordinary civil aircraft, the An-1250 physique and transportation type application is too troublesome, so it is much easier to directly use the relationship to register as a military aircraft, and the take-off and landing management are separated separately.

It was also at this time that the specific data and dimensions of the An-1250 were slightly spread in the Chinese scientific research community.

With a wingspan of 136 meters, a length of 130 meters, and a take-off weight of 1,250 tons, such an exaggerated figure is directly considered a rumor by most people.

……

On April 15, Xinyuan Company announced that from April 16 to April 20, flights were prohibited in the surrounding airspace.

Flight school, stop, commercial flying, stop.

The local public security cooperated with the military to ensure the absolute clearance of the surrounding airspace.

At the same time, in the previous week, Xinyuan sent invitations to a number of units to watch the first flight of their new model on April 19.

Including provincial and municipal leaders, space bureau bosses, superiors, old acquaintances of various aerospace institutes, and some enterprises involved in the manufacture of An-1250 parts.

In the process of notification, the specific performance data of the An-1250 was also sent out at the same time, and many supporting companies knew that they had participated in a bullish aviation project.

And a group of superiors and leaders also understood that Xinyuan Company quietly dropped a bombshell in the aviation industry.

You're an aerospace company, hey, is it really good to cross the border like this!

At the same time, the aircraft design institutes in Huaguo also suddenly received a notice from their superiors that they should go to Xinyuan Company to see the test flight of the new aircraft.

The design institute was confused at first, and then looked at the data of the An-1250 and became numb.

Chang'an, Yan Liang.

Tao Changhong led the design team and just completed the basic design of the Yunyou 20, which has long been based on the finalization, and the next step is to use it as a flight test platform to derive a variety of models.

With a load of 66 tons and a maximum take-off weight of 220 tons, the Y-20 has become the sixth largest transport aircraft after the An-225, C5, An-124, An-22 and C17, which basically meets the current needs and is very good.

On this day, I suddenly received an order, saying that Xinyuan Aerospace Power Company, the aerospace company, had built a transport plane for transporting spacecraft, and many people were invited to the first flight, and the superiors decided to let each aircraft design institute go to a few people.

Tao Changhong is very puzzled, he is no stranger to Xinyuan Company, Xinyuan also rented an Il-76 modified to transport spacecraft, how can he build it himself, an aerospace company, at most a small transport aircraft across the bank, right? What did the superiors let them do?

Then, he got the data of the "small" transport plane shared by Xinyuan.

The An-1250, designed by Anderov, has a maximum take-off weight of 1,250 tons, a wingspan of 136 meters, a length of 130 meters, and is propelled by eight XW-30 engines of 330KN.

The first thing he thought was that it wasn't a joke that someone didn't make.

If nothing else, just this 330KN engine, how come there is no news at all about such a powerful engine, and it will come out silently? The thrust of the turbofan 20 is only 160KN!

XW-30: This is going to be one and two on top!

The largest thrust engine he knows Xinyuan has is still the XW-10 with 150KN, which is too big, right?

After repeatedly confirming with his superiors, he realized that this was really not a joke, the An-1250 is a giant transport aircraft with a take-off weight twice that of the An-225!

How this thing was made!

Tao Changhong stared at these parameters and imagined them for a long time, and he didn't understand how this super giant appeared silently.

And when he was confused, Yang Wei was also confused.

On April 16, the An-1250 ground gliding test, Yang Wei and the leaders of the local military region were present, as well as some enterprises that supplied An-1250 accessories.

Shu Oak Group is an enterprise that undertakes the research and development task of An-1250 special tires and accepts the technical guidance of Xinyuan engineers to produce tires.

The person who came was the person in charge of the project, to be honest, this batch of tires did not ask much, although the unit price was not low, but the total amount was not outstanding, it was completely for the face of Xinyuan Group.

When the person in charge took over the project, he was very surprised, and he didn't know what kind of working conditions would be able to use tires with such a high standard, and he also needed to carry out technical difficulty public relations, but now he understands it.
