In March, the Oasis New Town Launch Center, the launch site of the first polar-orbiting satellite rocket.

At this time, Zeng Qingfeng was a little nervous, because this was the first time that Xincheng had launched such a rocket in deep space, and he was worried about failure.

It is obviously not an easy task to send a satellite to the depths of space 36,000 kilometers above the ground.

The difficulty coefficient is not much worse than launching a space station.

But nervousness is nervousness, and the work still has to be done.

Zhou Jimin is extremely determined, because the rocket launcher was researched by him, and naturally knows better than anyone whether this launch will work or not.

Before the rocket was sent to the launch center, it was not just he himself who checked it three times, but also other staff members three times.

Just after refueling, he checked again to make sure that there was no problem with the rocket launch.

All the crew left the launch tower and the satellite launch entered the final stage of the countdown.

At this time, Lao Lin was also standing next to him, he was the only leader who came to the Xincheng launch center this time.

"Yes, in ten years, you have developed this place so well, great!"

Lao Lin had just arrived in Xincheng today, and he was picked up by a Type 65 improved passenger plane from the troops, and it was not Zhou Jimin who picked him up.

Today's Oasis New Town, although it has not yet mastered more advanced aero-engine technology, has made great progress in aero-engines.

The Type 65 improved passenger aircraft is an aircraft manufactured by the latest engine completely independently developed by the R&D team of Xincheng Aircraft.

The maximum take-off weight of this aircraft is two hundred and twenty tons, the maximum landing weight is one hundred and eighty tons, and the thrust of a single aero engine reaches thirty tons......

All the data indicate that the technology of this aircraft has reached an extremely striking level.

Such an awesome technology, of course, was first applied to the troops and became a transport aircraft.

Actually, this thing can't be used as a transport plane, but there is no way, this is the limit of the new city at present.

Originally, Xu Lei developed aero engines in accordance with civil airliner standards, but today's domestic civil aviation market is extremely underdeveloped.

For the time being, it is impossible to sell the engine abroad, so it can only be digested internally.

When the troops heard about it, they were so excited that they danced hand and foot.

Because such a huge thrust engine can completely make a transport aircraft, for the troops, the role of the transport aircraft is really too great.

No matter what the occasion, having the ability to react quickly in combat is the key point that the troops should consider.

Lao Lin liked the plane very much, because he saw the future of the country.

"Comrade Panda, do you think it's possible that we will also develop a Chinook heavy transport helicopter?"

Zhou Jimin glanced at the rocket that was about to be launched, and said softly:

"Yes, but it takes time."

Not to mention, Lao Lin thought about it quite carefully, and Zhou Jimin himself didn't think of this.

Heavy transport helicopters that can drop soldiers and supplies in their respective environments are indeed very good equipment.

Especially in the process of disaster relief, such a heavy transport helicopter is really too important.

The Chinook heavy transport helicopter, developed by Bald Eagle more than a decade ago, can not only hover in the air, but can also transport 33 heavily armed soldiers or eight tons of cargo at a time.

Its combat radius is 370 km, its maximum range is 2,200 km, and its maximum flight speed is 315 km/h.

Perhaps if Zhou Jimin uses the electric propulsion system as the main thrust, he can also save part of the take-off weight of fuel, which can improve the transportation capacity and combat radius.

Our country is vast, and for such transport helicopters, it is too urgent.

Lao Lin did not continue to talk about this topic, because the rocket at this time had already breathed fire.

With the huge coming from afar

With a roar, rockets rose from the ground.

At this time, the old and new city halls were filled with people in front of the TV screens in the major canteens, squares or their homes.

After years of development, television sets have also become popular.

Basically, it can be said that every household has a television set, and the penetration rate is as high as 80 percent.

Many public areas, such as school canteens, unit canteens, cinemas, squares and other areas, also have public televisions.

At this time, without exception, all of them were watching a live broadcast of a satellite rocket launch.

The new city with the low-orbit global satellite system wants to broadcast the satellite launch live, it is simply not too simple.

Of course, once the rocket is deep into space, it will be difficult to catch the signal.

Even if there is a signal, it will be too far away to see clearly, and it will not be attractive.

After all, the place that this satellite needs to go to is 36,000 kilometers from the ground.

Watching the live broadcast of this rocket launch, the pride of the residents of the new city instantly increased a lot.

Many people are excited, and many students have the urge to change majors and apply for astronaut exams immediately.

The rocket lifted off smoothly and soon entered space.

After entering space, the speed of the rocket not only did not slow down, but accelerated a lot.

If it is said that the launch is a space station, or a low-orbit artificial satellite, then the time taken is very short, in general, a few tens of minutes are enough.

Because we know that the journey to outer space is very long, and it can be done in such a short time, it is said that it is very fast.

It's just that the current launch is a polar-orbiting satellite, so the time required is very long, about ten days.

Oasis New City uses a multi-stage rocket launch method to launch polar-orbiting satellites.

It's expensive, but it's still affordable.

At present, polar-orbiting satellites have come to an orbital range of more than 200 kilometers, and from this place to a polar-orbital orbit of 36,000 kilometers, the rest depends on time.

Lao Lin naturally wouldn't wait that long, so after the launch was completed, he left the launch center when he learned that the polar-orbiting satellite had entered the normal orbital flight.

In the next two days, Lao Lin visited the new city, whether it was a greenhouse vegetable planting base or a zoo, he went to see it.

He even visited several squares of the city.

In short, he went casually and did not plan his trip in advance.

Lao Lin also visited the six university campuses and felt very shocked.

The campus is very large, and the green area is also very large.

It's just that Lao Lin is a little puzzled, why are the trees on both sides of the campus of these six universities towering trees?

Visiting these campuses makes him feel like a newly built university, with too many big trees.

On the contrary, it is the same feeling as visiting a century-old school, which is very unusual.

Except for the academic buildings, libraries, student dormitories, and teachers' villas, which look like new buildings, everything else is leafy and does not look like a new campus.

"Leader, our six university campuses are all built in the original forest, and these trees have grown for at least ten years, so you see, this campus is so different."

Lao Lin nodded suddenly, "Do you still have any such big trees in your new city?"

"That's a lot, there are big trees like this everywhere around our new town, and they are almost more than 50 years old......

A tree that is more than 50 years old, which is very unusual.

You must know that the new city is built on the desert, and in just ten years, it has not only given birth to a large city with a population of more than one million, but also has a very high urban forest vegetation coverage.

Within a hundred kilometers around the city, almost all of them are large trees, and even some places

There are also swamps.

In addition, there are also very rich species of flora and fauna in the forest, not only poplar and sand cats endemic to the Taklamakan Desert region, but also rare species in the primeval forests of North and South America and the deserts of Central Asia.

It's a paradise for all kinds of species.

These species weren't supposed to be together, but they didn't just get together, they built perfect ecosystems.

It is perfectly balanced, and the numbers of the various species are the same, and they are kept at a balanced level, neither overflowing nor extinct as a result.

How, exactly?

Lao Lin didn't study these too much, because it wasn't the point.

After he visited the electric propulsion engine that Zhou Jimin was studying, he again brought up the matter of the heavy transport helicopter.

"Leader, don't worry, as long as you approve the documents, I will gather people for research and development as soon as possible."

"You've built all the engines, aren't the current electric propulsion aero engines already capable of driving airplanes to a speed of 1,000 kilometers per hour? Just change it."

Hearing Lao Lin's doubts, Zhou Jimin suddenly cried and laughed, and hurriedly explained to the leader.

The electric propulsion system can be fitted with two engines on the jet, or four engines can also be installed.

So what Lao Lin just said is right, it can indeed achieve a flight speed of 1,000 kilometers per hour.

However, the thrust of a single electric propulsion engine is currently only about ten tons.

And this is only for jet engines, not helicopters or other aircraft.

If it is replaced by another aircraft, it is necessary to change the style of the engine, or even directly re-push it and develop a new engine.

Scientific research is not so simple, it must be rigorous.

After listening to Zhou Jimin's explanation, Lao Lin didn't say anything more.

Of course, after going back, he must sign the approval documents as soon as possible, so that Zhou Jimin can lead people to hurry up and develop this heavy transport helicopter.

This kind of weaponry continues in many places, which is really important for the troops, and it is also very useful.

When Lao Lin left the new city, Zhou Jimin quickly set up a research and development team in the laboratory.

It's just that there's no one left!

It's too short of people.

Fortunately, the army soon sent a research and development team of more than 50 people, all of whom were experts in aero engines.

You can have this!

Zhou Jimin sent the information to them, so that they could hurry up and understand the electric propulsion system, and then start research and development work.

Ten days later, the first polar-orbiting satellite successfully reached the scheduled orbit, and the news was broadcast on Xincheng Satellite TV that night, and the whole city was boiling for a while.

In the Zhou family's villa, Zhou Qingyi and the others also sat in front of the TV, watching TV while eating dinner.

For the millions of residents of the new city, it is customary to watch the news broadcast on time at 7 o'clock every night.

A lot of what happens in Xincheng will be fully broadcast during the news broadcast.

Not only the local news of Xincheng, but also the international news will also be reprinted or directly broadcast.

Yes, the reprinted news, the TV picture will be standard and clear.

At present, there are only two channels in the entire Xincheng TV station, one is the news technology channel, and the other is the entertainment channel.

The two channels are similar, and the morning, noon, and evening news at a fixed time are all broadcast in the same way, with the same host and the same program.

At other times, there are either popular science programs for science and technology projects or TV dramas, which are different.

"Dad, are polar-orbiting satellites really that powerful? Is it really possible to broadcast the weather forecast in the future? Isn't that allowed?"

[At present, it is the most complete and best app for listening to books, integrating 4 major speech synthesis engines, super 1.]

00 kinds of timbres, but also an artifact that supports offline reading, App]

A few little guys were very curious, because the announcer had just briefly introduced the main role of polar-orbiting satellites, and they already knew it.

In fact, as early as ten days ago, in the live broadcast program on the day of the launch of the polar-orbiting satellite, the host had already introduced it in general.

Polar-orbiting satellites are technical improvements made in response to the current space station, weather forecasting, etc.

"Won't you know when the time comes?"

Zhou Jimin took a bite of food and said vigorously.

Ding Qiunan said with a smile: "I think this is very good, many new technologies should be popularized to improve our national self-confidence."

Zhou Jimin didn't say anything about this.

There's no point in arguing with her, nothing but making everyone unhappy.

Whether the new technology will be announced or not depends on the situation.

The space engineering project is no secret in Xincheng, and polar-orbiting satellites can also openly broadcast the progress of the launch.

That's because Zhou Jimin has confidence in his own technology, but also in the staff of the entire space center.

Nature is not afraid of some tragedies that will happen as a result.

Besides, it's just a simple science popularization, and it has nothing to do with technology.

There is no risk of technology leakage.

In today's new city, how can it be so simple to enter the new city and become a resident of the new city?

The entire new city is located in the Taklamakan Desert area, surrounded by natural barriers such as deserts and the towering Kunlun Snow Mountains, and there is no fear of outsiders at all.

What's more, at the junction of the desert and the forest around the new city, as well as in some places in the forest, several monitoring belts have also been arranged, who can escape and enter the new city without a license?

No one can do it!

Even the two channels of Xincheng TV are not received at all except Xincheng and Liuer Town.
