The group continued to discuss the issue of length 12.
At some point, Zhang Peicai sighed with emotion. "Speaking of which, it can be successfully put into use for 11 years, but thanks to your company’s nano-mineral powder, otherwise there is no way to improve the performance and mass production of the cermet materials of the Science and Industry Corporation."
Huang Xiuyuan really admires aerospace science and technology. After all, he can develop rapidly with the accumulation of future science and technology.
"The technical bottom of the Science and Industry Corps can still be achieved by powder metallurgy in my snail industry, and the high-temperature resistant materials in the laboratory can reach 3756 degrees Celsius."
"Let’s take a look at the problem of controlling solid fuel combustion!" On the side table of Academician Wang Kan, let the assistant clear out an area and give everyone a seat.
The problem of N2 fuel combustion control is also a huge trouble. Solid fuel has the disadvantages of solid fuel, and it can’t stop the fire at all. For missiles, it is not a disadvantage, but it is a big problem for carrying rockets.
This is also why the long 11-core secondary stage has to adopt hydrogen and oxygen fuel, because the solid fuel will stop when it catches fire.
I plan to go to the moon to explore the outpost. 1 If solid fuel is used, there is no way to carry out fine control, and I can rush to the end by brute force.
If you can’t reach the designated orbit before the fuel is exhausted, it will be wrong to make mistakes in the end.
There are several research institutes in Aerospace Research Institute engaged in precise combustion control of solid fuels, but the results are few.
Chapter two hundred and ten Visiting the motorcade
June 15th
Alxa League Dongfeng Aerospace City Wan Liyun
This kind of sunny weather without dust and fog is the ideal weather for space launch.
The white painted Chang 11 rocket has arrived at the south launch site of Dongfeng Aerospace City by transport vehicle, which is the main site for launching Chang 2 rocket.
The launch pad, fixed launch tower and 11 rockets will be fixed. Aerospace technicians and engineers are carrying out the last inspection.
The launching room of the mobile tower, which is responsible for the last inspection, meticulously inspects all parts of the rocket through the automation system and various testing instruments.
Because Chang 11 is not needed for solid fuel rocket transportation, the fuel is reduced for a long time.
Command and control center
Nie Guanghua and others are so busy that the control center, communication time system center, data exchange processing center and weather astronomy real-time monitoring class are connected to other areas for measurement.
These complicated things and small-scale countries are really not qualified to play space exploration.
Huang Xiuyuan stayed in the lobby lounge of the command center without actually participating in the space launch and rubbed his temples to repose.
There are also Zhang Peicai, Wang Kan and others. They are mainly too old. They are all in their fifties and sixties, and they are physically and mentally exhausted after tossing.
Pushing the door from the outside with a pair of panda eyes, the whole person is depressed and I don’t know if people have returned him to too much sex.
Huang Xiuyuan smiled and poured him a cup of tea with his eyes open. "When General Zhang comes, he will come to have a cup of tea."
Some hearts shook their heads and smiled bitterly. "I can’t sleep for a day without this satellite."
"All right, stop dangling. I’m almost dizzy from you." Wang Kan knocked on his forehead.
Fidgeting and restless, even if you sit down, you still seem to have ADHD. From time to time, your eyes aim at the control center outside the window.
One minute passes by.
the other side
The highway from Jinta County to Dongfeng Aerospace City was closed a few days ago.
A motorcade of news media and special guests headed for Dongfeng Space City and went to Jiuquan Space Center after passing the whistle, and the alert level was higher than Wenchang’s.
Driving in the vast wilderness, the front bus was specially invited. Asahi Shimbun reporter Hasegawa Kenichi picked up his camera and pressed the shutter in the northeast.
In the midsummer morning, the sun rises from the northeast horizon, and the red sun actually makes Hasegawa Kenichi a little absent-minded.
The desolate Gobi desert occasionally has patches of grassland flashing to show their tenacious vitality, just like the history of this barren country.
He was accompanied by Wayne, a reporter from the German Mirror.
They are one of the few foreign media people in the news media invited this time.
Wayne asked slightly, "Mr Hasegawa, what do you think of this invitation?"
The mood is a little complicated. Hasegawa Kenichi let go of the camera. "They are more confident and more willing to show their strength to the world. It used to be the same in Japan."
"…" Wayne, a German, also seems to feel the envy and jealousy of Kenichi Hasegawa and finally sigh "The rise of great powers is easy to talk about"
Japan’s broken backbone, Germany’s taste is not the same. Although relying on the economic core position of Xizhou Alliance, together with Gaul and Britain, it can affect the whole Xizhou Alliance, but the German Empire is a thing of the past after all.
Just as Hasegawa Kenichi said, China has always closely protected Dongfeng Aerospace City, and rarely invited foreign news media to watch and interview it.
This time, reporters from Asahi Shimbun, Mirror and Nanyang United Daily News were suddenly invited, which was naturally not simple.
The rise of Dalian Stock Exchange has given China a card to lift the table, and its influence on the world economy is almost equal to that of oil and gas.
The frequent testing of super missiles and high-energy explosives in the previous period made the world fall into silence.
This rise in economy, science and technology, and force has in turn driven national self-confidence and people’s self-confidence
Only this time, Dongfeng Aerospace City invited the world to see what technology and power are.
After more than an hour.
Hasegawa saw the five characters "Dongfeng Aerospace City" and he consciously picked up the camera and took some photos.
The coach also stopped at this time.
Because they have to undergo a strict inspection before they can enter the space city.
Hasegawa, who just wanted to take pictures, was warned by a side worker that some areas are forbidden to take pictures, and they will check their equipment when they leave, hoping that they will cooperate with the work.
Awe and obedience to the national characteristics of the strong made Hasegawa immediately bow and apologize. "I am very sorry for the trouble."
"I can confiscate your equipment if I violate the regulations again," the worker warned seriously
"hey! I am very sorry. "
After the inspection, the bus followed the team into the space city.
Although it is to build a Gobi desert city, the landscaping of the space city is very good, and the colors are full of flowers and trees, which is not like a desert city.
Soon the team entered the vicinity of the launch site.
