Chapter 416 Heavy Long March 10 Rocket Technology Seminar: First Flight and Head-to-Head Showdown with SLS Rocket!

Most netizens have been criticizing "Gentlemen of the East Eighth District" for several days and are tired of it. Now only a small number of people are continuing to criticize it and are even persisting in reporting it, determined to get this trashy TV series taken down.

On the 26th, "Godzilla vs. Kong" was released, and the "Wandering Earth 2" crew went to see it together after finishing a day of filming.

Director Guo has not forgotten his dream of making a domestic monster movie.

Godzilla vs. Kong is a standard commercial blockbuster, but Lu Yun remembers that it didn't seem to be a huge hit in its previous life; it probably only broke even.

At most, you'll make a small profit.

If his memory serves him right, the global box office of "Godzilla vs. Kong" in his previous life was over $400 million, of which Chinese people contributed $170 million, while North America's box office was less than $100 million.

It's clear that Chinese audiences still really enjoy monster battles, and Director Guo's domestic monster movies have a certain audience base.

Of course, the premise is that it looks good.

After all, Lu Yun knew that the famous "749 Bureau" was already in the later stages of production.

Without the impact of a pandemic in this lifetime, "Bureau 749" might be released earlier than expected, instead of being delayed until 2014.

However, Lu Yun didn't dare to make any guarantees, since the mental state of Director Lu was something that most people couldn't fathom.

Lu Yun spent most of March on set, and any issues with the aerospace engineering were mostly resolved via video conference. However, he still made a trip to Beijing at the end of March.

Because a technical seminar on the heavy-lift Long March 10 rocket was held.

Following the successful maiden flight and recovery of the Long March 10 basic rocket, China's manned lunar landing program was officially put on the agenda within the aerospace system.

The recovery size of the Long March 10 basic rocket is similar to that of the Long March 5 rocket. The national team does not actually have a great need for this type of rocket, especially since there is basically no short-term demand after the completion of the first phase of the Tiangong space station.

The term "short-term" here is measured in "years".

Basically, it requires large-scale deep space probes like the "Tianwen-1" Mars probe and the "Long March 5" lunar sample return mission, as well as large-scale sun-synchronous orbit experimental satellites.

But this kind of demand might only occur once a year.

The previous life was similar; there was basically no great demand for large and heavy rockets in various countries.

Until Elon Musk developed a space-based internet network with tens of thousands of satellites.

After that, Laos and China also wanted to develop space-based internet, which is why they vigorously developed reusable rockets, with both state-owned enterprises and commercial companies involved.

They were afraid of falling too far behind.

This life is different. Lu Yun developed reusable rockets much earlier and proposed the "Zhou Tian Xing Dou Grand Array" much earlier.

Faced with the launch requirements of 10,000 satellites for the "Starship Troops" mission, the "Wanhu" rocket, a mainstay in the international aerospace field, is somewhat small, with a carrying capacity of only about 60% of that of the Falcon 9 rocket.

The Long March 10 is different; it not only has a large fairing, but its recovery payload capacity also reaches 25 tons.

In comparison, the recovery capacity of the Falcon 9 rocket is only about 70% of that of the Long March 10 rocket.

With such a large carrying capacity, the Long March 10 can launch 80 "Xingdou" first-generation sub-satellites, each weighing 300 kilograms, in a single launch.

It's no longer the case that the number of "Stardust" satellites launched by the Wanhu rocket twice is equivalent to the number of "Starlink" satellites launched by the Falcon 9 once.

The cooperation model for the Long March 10 rocket is similar to that of the Wanhu rocket, where both the national team and Bluestar Aerospace can produce and use it.

As a result, the production capacity that the satellite factory had just increased was no longer sufficient, and they needed to continue to increase production capacity.

Previously, it was uncertain whether the Long March 10 rocket would be successful, so the increase in production capacity was somewhat conservative.

Fortunately, ramping up production capacity is not too difficult for Chinese people.

With the addition of the Long March 10 rocket to its launch vehicle, the number of satellites in orbit for the "StarDou" satellites this year will certainly surpass that of "Starlink" by a significant margin. Furthermore, the 7-meter diameter fairing for the Long March 10 rocket is nearing completion, so the development of the first-generation "StarDou" node satellite, weighing 800 kilograms, is also being accelerated.

It has stronger communication capabilities, allowing regular smartphones to connect directly.

Today's technical seminar revealed that the technical progress of the Long March 10 heavy-lift rocket is also quite encouraging.

"...The core technology of the heavy-duty Long March 10 is the already successful basic Long March 10 model!"

Lu Yun pointed to the rendering on the big screen and said, "The CBC configuration of the heavy Long March 10 is three basic Long March 10 rockets bundled together as a single booster. Although our country does not have rockets with this configuration, we are still very familiar with the concept of 'bundled boosters'."

At this point, Lu Yun asked the representative from the First Academy: "How is it going? We've progressed from the initial 2.25-meter booster of the Long March 2 rocket to the 3.35-meter booster of the Long March 5 rocket. Are there any problems with now building a 5-meter booster?"

"It's not a big problem."

A representative from the First Academy stated, "We have made a breakthrough in booster diameter and solved the important separation problem. We are now conducting overall vibration tests, and the progress has reached 90%."

Lu Yun nodded upon hearing this. It was indeed not a big problem, and he should be able to master it all soon. So he continued to point to the renderings and analyze.

"The second stage of the heavy-duty Chang-10 is an upgraded version of the second stage of the basic Chang-10. This has been resolved before, so I won't go into details."

"The heavy-lift Long March 10 has added a core three-stage rocket, which is not present in the basic model, in order to improve its high-orbit payload capacity."

Lu Yun pointed to the Long March 5 Heavy-lift three-stage rocket, which was significantly taller than the basic Long March 5, and said, "It uses liquid hydrogen fuel, and its three hydrogen-oxygen engines are an improved version of the second-stage engine of the Long March 5 rocket. How is the progress?"

The representative from the Sixth Academy immediately replied, "No problem. Because the increase in demand is not a leap, our improvements are progressing smoothly. We are already conducting full-system testing, and the testing is going very well!"

Lu Yun nodded upon hearing this, the development progress of the heavy-duty Long March 10 was much better than he had expected.

The primary recycling technology, which I will discuss later, is also fine.

After all, the core of the heavy-duty 10 is the basic 10, and the basic 10 has already completed the first-level recycling task.

As long as the three first-stage rockets of the Long March 10 heavy-lift rocket can separate successfully, they can land smoothly according to the basic Long March 10 flight control system.

As the First Affiliated Hospital just mentioned, the safe separation technology has been successfully developed.

Although the Long March 10 has a larger booster, China's rocket booster technology path is very clear, progressing smoothly from 2.25 meters to 3.35 meters, and then to 5 meters.

If the technology for the Long March 10 heavy-lift rocket is summarized according to these technical milestones, and if progress goes smoothly, it is highly likely that...

Lu Yun calculated in his mind.

It's highly likely that the maiden flight will take place next year!

next year……

In the previous life, the SLS rocket from the US was scheduled to make its maiden flight next year, and in this life, they have decided to do the same again next year.

The only difference is that in the previous life it was at the end of November, while in this life Boeing has given the first flight time to the second quarter of next year.

The SLS large rocket was initiated and researched ten years ago, but unexpectedly, its maiden flight will be on the same table as the heavy-lift Long March 10 rocket, which only started research this year.

The SLS can't even sit at the same table as the Long March 10 Heavy, because the Long March 10 Heavy is a reusable rocket, while the SLS is a disposable rocket.

So much so that in the previous 25 years, after Ma Yilong "entered the cabinet and took power," there were many rumors that it would be abolished.

That's because it's not only slow, but also extremely expensive!

At the time, Elon Musk was locked in a fierce struggle with the congressmen who had been lobbied by Boeing. He wanted to cut funding and cancel the project, but Congress absolutely refused.

After many repetitions, Ma Yilong offended everyone, and even fell out with Trump in the end, resulting in him being kicked out.

Ma Yilong is very angry, even a little crazy, and wants to create a new winning streak!
