"Director Lin, it's early."

"You're too, early."

From February 5th to February 14th, it is Xinyuan's annual leave time, but at the end of January, many employees can leave with the rest days they usually accumulate, so basically there are 20 days when the B-level base is semi-suspended.

During this period, except for a few personnel who had to stay in the positions, system engineers, security departments and Lin Ju, there were not even a few cooks left......

There are only a few Xinyuan local ones in the security department, and the family is deserted, and the uncle who is about to 60 from the tractor factory is watching, but there is no problem, because there are soldiers patrolling outside the B-level base.

On the periphery of the base are patrol troops organized by the local military region, and there are various open and secret outposts in the surrounding 10-kilometer area, and no outsiders can casually blend in.

Lin Ju can receive some reports from time to time, and the number of unknown people in the surrounding villages and counties is increasing rapidly, but fortunately, it is impossible to rush through the layers of guards to get close to the base.

In addition, there are a huge number of cameras and sensors inside and outside the base, and the "mountains and seas" faithfully monitor them, and there is absolutely no possibility for the security guards to doze off and put something in.

Lin Ju took a morning jog to breathe fresh air under the protection of countless people in the dark, and then returned to the small cafeteria to eat with the system engineers.

The chef and the cleaning aunt who stayed behind discussed in a whisper, and they had discovered a phenomenon, the big boss and several senior engineers were all single, which was a miracle.

Lin Ju, who didn't know that he was dissed, was still discussing his plans for the next year with the engineers.

The most important thing is the NAPE nuclear propulsion plan, Cheng Nankai has basically thoroughly understood the basic reactor design in more than 7 months, which involves more than 1,300 new technologies, more than 200 of which are major difficult technologies.

The budget requirements for 2016 have been increased to 6 billion yuan, of which more than 4 billion yuan is for supporting enterprises to carry out new technology and equipment manufacturing research, and the first test reactor is expected to be put into trial operation from October to November, and the design of the XN90 spacecraft will be carried out and technical preparations will be carried out.

At the same time, the technical verification of ionization-gas tip joint propulsion will be carried out, and the prototype will be manufactured in July and September.

In 2017, the nuclear propulsion team decided that it would take at least half a year to master the perfect joint propulsion of the three, and a total of 5 prototypes were built, and the A100 was to be finalized at the beginning of the same year, and the H2 equipped with a nuclear thermal engine must make its first flight before the end of the year as a backup for the NAPE delay.

Although the system has a full set of technical data and experimental data, if you want to fully grasp and have the ability to develop yourself in this area, you still have to go through it yourself.

Actual NAPE-ready engines had to be built in October 2017, and construction of the first XN90 spacecraft began.

In the middle of 2018, the XN90 spacecraft equipped with six NAPE rolled off the assembly line, conducted two test flights that year, and carried out a manned mission to the moon as early as January 2019, with only six months left before the end of the system, enough for an unexpected event.

To be on the safe side, the goal for 2016 is to complete the design and manufacture of the H2 space shuttle's airframe, starting with the manufacture of two conventionally powered versions with liquid oxygen methane engines.

Because this year, Xinyuan officially began the construction of the "forward" centrifugal space station, which needs to be assisted by a large space shuttle.

Five more Xinyuan-2 will be manufactured to form two Xinyuan-2A and two Xinyuan-2, the former to be specially modified to send the 130-ton weight of H2 to the sky, and two Xinyuan-3 giant rockets, which will also make their first flight soon.

This year's budget is conservatively invested 30 billion yuan, and the funds are still sufficient, and there will be many manned commercial flights intensively, which can earn a lot of money.

On February 15, the two bases of Xinyuan Company officially started.

After all-out recruitment, the number of employees officially joined finally exceeded 3,000, of which more than 400 came back from abroad and were attracted by Xinyuan Company.

Many people pass the interview at the end of the year and only officially start work at the beginning of the year.

Coupled with the personnel seconded from the university, the B-level base is finally able to operate at full capacity and exert its terrifying manufacturing capabilities.

Anderov crammed more than 100 people into the workshop of An-1250, carried out two shifts to speed up the efficiency as soon as he came, and at the same time sent engineers to various supporting enterprises to urge and demand delivery as soon as possible.

He is now in charge of the manufacture of multiple rockets, space shuttles, and airplanes, and has more than a dozen departments under his jurisdiction, and his schedule is full.

The four rocket bodies of Xinyuan-3 entered the manufacture at the same time, and the production plan of the Ministry of Aerospace Power for K380V alone is 100 units, and it will be completed within 3 months, with an average of one per day.

The more than 4,000 chips produced by the silicon carbide production line during the Chinese New Year were divided among various departments in one day, and I don't know where they are going to be used.

……

Sixth Academy, Chang'an engine manufacturing base.

After 4 months of struggle, the YF130 design has been finalized, and parts have been sent to all units for production.

In March, the joint test of gas generator and turbine pump was carried out, the prototype was manufactured in April, and the first batch of 16 YF130s was produced in June at the latest.

Now the parameters of YF130 have been slightly improved, with a double-tube thrust of 510 tons and a specific impulse of 294 seconds, which can make the take-off thrust of the Long March 10 reach 5,100 tons, allowing astronauts to return to Earth with an extra 100 kg of mass.

Stimulated by the 2921 Project, the size of the scientific research team of the Sixth Academy has expanded to 1.5 times, and it has also successfully established an engine production line based on the needs of the Long March 10 in the future, which can mass-produce high-thrust engines instead of being manufactured by hand, approaching the route of specaX and Xinyuan.

This also saves a lot of time, because mass production makes the cost lower, and several prototypes can be tested in a row, and commissioning is no longer something that requires careful preparation.

Therefore, the Sixth Academy even has the spare strength to decide to carry out the YF90, 220-ton hydrogen-oxygen engine development plan.

Although the vacuum version of the Long March 10 II with four YF77 is also OK, the parameters of the YF77 itself are relatively backward and must be upgraded in the future, so the YF90 prepared for the Long March 9 is on the horse.

The YF79 used in the three-stage rocket, the new 25-ton closed-type expansion cycle hydrogen-oxygen machine is progressing faster, and the design work is gradually being completed.

But the Sixth Academy did not think that these future high-thrust engines were advanced, because at this time they gradually knew that Xinyuan's nuclear-powered engines had been advanced for several months!

The reason for this was that the nuclear test site next to the B-class base was completed, and the research institute under the space agency knew that there was actually a nuclear propulsion program going on there.

The specific project is unknown, but it is highly likely the A100 engine, which Anderov once said.

That's a nuclear-powered engine that's more than 20,000 impulses, and any chemically powered engine is a pile of garbage in front of it.

The Sixth Academy itself has also carried out a demonstration plan for a nuclear engine, and the ratio is only about 1,800 seconds, although it is high enough, but it is still much worse in comparison.

However, the superiors still had no intention of following up, which made the Sixth Academy a little anxious, and while organizing a team to conduct nuclear propulsion research, it also reported to the authorities:

Big man, you don't want us to fall behind everywhere, do you?

Space Agency: Not approved.

The nuclear engine program is too expensive, and when Huaguo Power Investment cooperated with Xinyuan, it believed that it would take about 40 billion yuan to complete the entire plan, and it would be difficult for the nuclear power reactor to recover so much value of this 40 billion yuan.

And even if you go to Mars, you can do it with traditional engines, and the nuclear engine is to explore Saturn and Jupiter, and the next generation of talents will do it, and the preparations made will not only have a spaceship.

The Sixth Academy, which had been deflated by its superiors, decided to continue the theoretical research on nuclear propulsion under the leadership of Tang Weitian, and at the same time decided to promote the development of methane-fueled engines.

The methane machine is not particularly difficult, the configuration is similar to the hydrogen and oxygen machine, but the performance of the previous methane machine is very bad, especially the specific impulse is not high, not as good as the kerosene machine and the hydrogen and oxygen machine.

However, the Sixth Academy of Research in this area does not want to be left behind, methane has a greater advantage than liquid hydrogen in terms of acquisition and preservation, and it is also a low-temperature fuel, and the design of the co-bottom tank is much easier.
