The rise of nanometers

The emergence of the canopy defense system is not only reported in the Western world, but also in China's own media.

The emergence of this system really surprised the allies. Whether it was the East Asian monster house, the Southeast Asian second-guessers, or the South Asian overlords, they were all frightened by the canopy defense system.

There are many test footage deliberately leaked on the Internet at home and abroad. In the overwhelming rain of rockets, not one of them penetrated the canopy defense system.

On the time blog.

The War Ignorance Bureau’s account updated an analysis video of the bureau.

On the domestic Internet, except for a small number of eccentric public figures, most netizens are teasing, joking and discussing.

As for foreign Twitter, YouTube, and Must Die, the attitudes of foreign netizens are mostly envy, jealousy, charisma, conspiracy theories, and threat theories.

However, recently, Suiren software has begun to appear all over the world except North America, including Time Blog, International Version of Chaoxin, Time Literature Network, and Time Film and Television, and these things have also penetrated little by little.

Just when there was a lot of discussion about the marquee system at home and abroad.

Huang Xiuyuan is still staying in the secret base in Baotou.

After he and Dr. Chen discussed some issues about multi-legged combat robots, Hu Li walked in: "Mr. Huang, Dr. Chen, the launch will be launched at Dongfeng Aerospace City in an hour."

"Oh? Then I'll wait and see." Dr. Chen said calmly.

"Is there a broadcast at the base?"

Hu Li nodded: "Not only are there broadcasts, but the several radar stations we control also undertake part of the tracking and positioning tasks."

The three of them came to the base's monitoring room together, where broadcast equipment was set up and more than a dozen staff members were busy.

After Dr. Chen sat down, he asked in a low voice: "I heard that the payload of length 12 is very large. How much is it specifically?"

Huang Xiuyuan knew about this issue. As the basic parameters of a space launch vehicle, there was no need to keep them secret.

"Low Earth orbit is 54.3 tons, geostationary orbit is 24.5 tons, and lunar orbit is 19.8 tons."

Dr. Chen rarely showed a hint of surprise: "So big? How much is the overall take-off weight?"

"The overall take-off weight is 824 tons."

After hearing this answer, Dr. Chen immediately calculated the load ratio of Chang 12: "The load ratio actually reached 0.0658. This seems to be higher than the previous Chang 11, right?"

Huang Xiuyuan explained with a smile: "What the doctor doesn't know is that the initial draft design of the Chang 12 has an overall weight of 824 tons, a low-Earth orbit payload of about 42.8 tons, a synchronous orbit payload of about 21.4 tons, and a lunar orbit payload of about 17.5 tons. "

Now Dr. Chen was even more surprised: "It has improved so much."

The low-Earth orbit of the Chang 12 launch vehicle has been increased from 42.8 tons in the first draft to 54.3 tons, which is an increase of 11.5 tons. This is a qualitative leap.

He wouldn't be too surprised if the total take-off weight increased accordingly. The key was that the overall take-off weight did not increase, but the payload did.

Seeing Dr. Chen's surprised look, Huang Xiuyuan immediately explained: "Because this is the first all-solid-fuel launch vehicle."

Totally solid?! Dr. Chen reacted instantly: "Have the second and third stages of the core been switched to N20 fuel?"

"It is a new design solution, which is a multi-stage engine and honeycomb multi-nozzle design, which can achieve precise control of solid fuel."

Dr. Chen knew everything about it. When he heard about the multi-stage engine and honeycomb multi-nozzle design, he knew the general idea of ​​the Chang 12 launch vehicle.

The original draft plan of the Chang 12 launch vehicle used solid fuel for the first stage of the core, and liquid oxygen and liquid hydrogen fuel for the second and third stages of the core.

The large orange tank of liquid oxygen and liquid hydrogen fuel occupies a large part of the dead weight of the launch vehicle. In addition, the fuel specific impulse is lower than N20. When the second and third stages of the core use nitrogen 20, the overall weight of the launch vehicle will be The dead weight will decrease.

The dead weight is reduced, but the fuel output power remains unchanged, so the payload naturally increases all of a sudden.

While the two were chatting, other scientific researchers in the base also took a break from their busy work and came to the monitoring room to watch the first launch of Chang 12.

On the launch tower of Dongfeng Space City, the Long 12 launch vehicle with a height of 83.2 meters has entered the countdown stage for launch.

"10...5...3...ignition."

Light red flames spurted out from the nozzle of the engine. In the heat sink below, a pool of hot water was quickly heated and evaporated by the flames.

The cleavage of the molecular bonds released surging chemical energy, pushing this 824-ton behemoth to fly towards the ninth heaven.

Driven by the radiant flames and cheered by the roaring roar, the Chang 12 carrier rocket, carrying mission equipment weighing 54.3 tons, and the space dream of all Chinese people, sprinted towards low-Earth orbit with all its strength.

In the tourist area of ​​Dongfeng Aerospace City, there was thunderous applause, and many people cheered and shouted loudly.

"pretty!"

"Success!"

"We also have our own big rocket."

In addition to the cheering audience and domestic media people.

There were also several reporters from foreign media. Their emotions were mixed at this moment, and they could only keep taking photos of the dazzling red light to cover up their embarrassment and complicated emotions at this moment.

Louis, a reporter from Gaul, looked up at the sky blankly, and the red light finally disappeared from his sight.

Putting down the camera, he glanced around. The smiling face reflected the vibrant spirit of a country.

When I think about the situation within the Xizhou Alliance, those gentlemen can argue for days over trivial matters. If they want to invest in and promote the aerospace industry like China does, it is basically impossible to reach a good agreement without several years of tussling.

Lewis felt confused and helpless about the future of the Western Continent Alliance.

"When is the next launch?"

"It seems to be November. I heard it's a manned space mission."

"Very good."

Louis, who could understand Chinese, felt even more envious and jealous when he heard the laughter.

Several other reporters from foreign media were also in no mood. After taking photos and videos, they hurriedly boarded the bus.

Louis also got on the bus, writing the press release and editing the video with his assistant.

After a while, waves of cheers came from the scene again.

Because the Chang 12 launch vehicle successfully broke through the Karman Line and entered the relatively safe bottom area of ​​low-Earth orbit.

After entering the bottom area of ​​low-Earth orbit, the core first stage of the Chang-12 launch vehicle still retains a lot of fuel and continues to escort mission equipment and circle toward the predetermined orbit.
