E: It's late today, continue to ask for votes, n-n)oi haha

On July 6, 257 (196 AD), Ejina County, Jiuquan City, Gansu Province, Dongfeng Base.

The Dongfeng base is China's first rocket and space test base. Its location is similar to the base of the same name in the original time and space, at the foot of Bayin Baogde Mountain in Ejina County. However, there is a slight difference that the Ejina region of the original plane is directly assigned to Jiuquan City, Gansu Province, which means that in the future, all the civil affairs near this base will be under the management of Jiuquan City, and of course, the taxes will also belong to Jiuquan City, so as not to be like the original time and space The two provinces are constantly arguing over the affairs of the base.

The area has an inland and desert climate, flat terrain, sparsely populated, little rain throughout the year, long daylight hours, and about 30 days a year can be used for launch tests. Moreover, it is deep inland, sparsely populated, and easy to keep secrets, making it the most suitable rocket test site in China. Of course, Wen Dehei, who has the information of later generations, is not completely copied, on the basis of the eastern base of the original time and space, he let his engineers and the main control optical brain "Xiao Fei" carry out a lot of optimization design, and in the layout and specific planning, some fine-tuning has been made to make it more reasonable and more convenient for future expansion and technological upgrading.

The Dongfeng base on this plane was built in February 1910, and by the end of February 192, the first phase of the project was completed, and the launch vehicle test began in earnest. In fact, before the completion of the base, before the CSD unified China, the CSD had already established the 33rd Branch of the Engineering Academy (mainly responsible for the research and development of rocket and aerospace technology) before the completion of the base, and had already achieved some results in the development of rocket projects in 1909. For example, the first generation of military rocket launchers and rocket artillery are some of the achievements.

However, in the past, limited by the venue, the 33rd Courtyard played with small rockets, and it was not until the Dongfeng base was completed that the research and development of large rockets began. Of course, when it is said to be "research and development", it is actually just copying. What engineers have to do is to realize those technical data of the "later generations" and turn the drawings into real objects.

But you must know that large rockets are very tall things, even if there are complete design drawings and process documents, it is not possible to turn into a physical object in a short time. What's more, the ability of the materials and process processing of the original plane cannot be compared with the "future generations", even if there is a complete technology tree data, it will take time to digest it.

Beginning in October 1913, the 33rd Courtyard was firing rockets at the base. Relying on sufficient funds and technical data, they continued to conduct tests, hitting rockets every two months on average, and so far a total of dozens of real Yàn rockets have been launched, each of which is larger than the other, and each of them is flying higher.

Of course, aerospace engineering is not about designing launch rockets, but also needs to consider many aspects, such as how to fly and navigate in space, the rendezvous of spacecraft, the remote control of ultra-long-distance spacecraft, and the survival methods of human beings in a vacuum environment, how to move under weightlessness, and the means of lunar exploration.

And then there's the key project right now -- artificial earth satellites, uh, mostly spy satellites. Then there is another sub-project - missile preparation, ballistic missiles. Cruise missiles are a project of the Eleventh Branch. Research in these areas is carried out in parallel with large launch vehicles.

In June 1914, the 330L Arrow Research Institute) had already hit the rocket to an altitude of 20 kilometers, which could already be said to have reached the boundary of space. At this rate, as long as the force is continued, at the most by the end of 1914, the rocket can be sent into orbit around the earth.

However, at this time, Wen Desi was not in a hurry, because the research and development of artificial satellites did not keep up. Can only rockets and satellites have a role? Could it be that hundreds of millions of yuan have been spent over the years just to listen to a sound and watch a big firework?

Therefore, in the past two years, on the one hand, we have continued to improve and optimize the rocket, and on the other hand, we have mainly carried out the research and development and ground testing of satellites and spacecraft. In addition to throwing them into a vacuum chamber, they were soaked in water, first in a pool and later into a lake in Qinghai to test for salt corrosion.

So it is only today that the launch of artificial satellites has really begun.

At this time, martial law was already under way dozens of kilometers around the rocket launch site, and hundreds of technicians were busy working in the central control building.

"Rao Gong, how is Feilian 5 ready?" the commander-in-chief asked the head of the rocket crew.

"Report to the commander-in-chief, we have just carried out the last test, a qiē is normal, there is no problem, and it can be launched as planned. The young man named Rao Jiaren replied excitedly.

Rao Jiaren is 28 years old, the son of a businessman, and has a natural interest in rocket research. He was the first batch of international students organized by Xingke Group, and studied in Berlin, Germany in 19uu, and after studying Wen Zong's "Materialist China", he had a premonition that the Oriental Lion was about to rise. After the newspapers came from the East one after another, he did not immediately return to China to feel the strength of the motherland like other classmates. Instead, he continued his studies in Berlin while studying rocket propulsion technology on his own. In 192, he had an accident while on a real yàn rocket, his rocket did not follow the intended orbit, deviated a few kilometers away and exploded on the ground on a farm, injuring several people (the first missile?). Fortunately, Sino-German relations were good in this era, and if he hadn't been a Chinese citizen, he would have been arrested and imprisoned long ago.

After Wen Desi knew about it, he immediately asked the relevant departments to investigate, and the results were very surprising, I didn't expect that there was such a rocket genius in this plane, this guy actually made a rocket with a range of more than 2 kilometers by himself without the technical information of later generations. So he immediately recruited him back to China. Later, with the technical support of later generations, his professional knowledge began to skyrocket, and his professional talent began to explode. In February this year, the world's first surface-to-surface ballistic missile was successfully developed, with similar performance and more than 20 years ahead of the original space-time.

This time, Wen Deji specially appointed him as the head of the rocket project of the satellite program.

The commander-in-chief nodded, and asked the person in charge of the satellite group, "How is Taibai 1 ready?"

The satellite team replied: "Report to the commander-in-chief, Taibai-1 is normal, there is no problem, and it can be launched as planned." ”

"The monitoring system is normal ......"

"Radar system is ...... normally"

"The remote control system is a qiē normal ......"

Subsequently, each project team began to report on its situation.

When the last project team finished reporting, the commander-in-chief looked at his watch and said into the microphone: "Okay, each project team is in place, according to the original plan, ready to launch"

The rocket launched this time, called Feilian 2, is a three-stage liquid rocket with a total weight of 10 tons, which can propel a payload of 66 kg to a low Earth orbit at an altitude of 20 kilometers.

"10,b...,2i launch"

At 6:06 a.m., as the countdown ended, a large amount of flames and smoke erupted from the bottom of the towering rocket, and the powerful thrust generated by liquid oxygen and liquid hydrogen fuel made the rocket soar into the air.

"The rocket engine is working fine"

"The tracking system is working fine"

"The radar system is working fine"

The first and second quarters of the rocket broke away one after another. At 6:14 o'clock, the third stage of the rocket turned off, opened the satellite protective cover, the satellite entered the preset orbit, began to unfold the solar panels according to the predetermined program, captured the three preset stars, began to correct their positions, and transmitted signals to the ground.

"Satellite positioning is done in a smooth way"

"Signal connection successful"

At this time, a burst of melodious classical music -- "Mountains and Flowing Water" -- came from the loudspeaker in the command center, which was a signal from a satellite.

"Success, success, success, we have succeeded" The command center immediately cheered, and everyone looked excited and enthusiastically supported each other.

Han Jing, State Council.

Zhang Lizheng, premier of the State Council, did not go home last night, got up at 5 o'clock this morning, and after eating breakfast, he has been guarding the red special line in front of him for a confidential telephone.

6:3, "Jingle Bell...... Jingle bell ......" the phone rings.

Zhang Lizheng immediately picked up the phone: "Hey, I'm Zhang Lizheng......"

"Report to the Prime Minister, the satellite launch plan has been completed smoothly, and now we have successfully established a signal ......link with the Taibai-1 satellite," the commander-in-chief's excited voice came from the phone.

Zhang Lizheng was stunned for a few seconds before he said excitedly: "Okay, please convey my congratulations to the comrades who participated in this plan, and I will immediately ask Mr. Wen for your credit."

After putting down the special line phone, he immediately turned on the handheld computer and contacted Wen Desi.

At this time, Wen Deji didn't sleep, and he got up before five o'clock today, waiting for news.

"Mr. Wen, the satellite launch is completed smoothly"

After receiving Zhang Lizheng's report, Wen Desi breathed a long sigh of relief: "It's great to give meritorious service to the units and outstanding individuals participating in this plan, and award medals."

The first satellite, called Taibai-1 and weighing 1,570 kilograms, is a low-orbit military reconnaissance satellite that operates in a low-earth orbit of 180 kilometers and has quite a lot of reconnaissance instruments on it. Almost everything that could be found in them, such as communication antennas, radars, high-magnification cameras, and high-magnification television cameras, was crammed into it.

The satellite will operate in orbit for three years, and although it can directly transmit encrypted video and image signals to the ground, due to technical limitations, the signal is not very stable and the clarity is not very satisfactory. Therefore, it also uses the re-entry capsule to drop negative film to the ground, and after several detours to shoot the negative of a film, it can be returned to the ground. The Qiming-1 had a total of eight rolls of film on it, so there were eight rolls of return. However, due to current technical limitations, the performance of cameras and camcorders is not very top-notch, and the weight and caliber are not large.

A few days later, the main persons in charge of the satellite program came to Hanjing to report to General Wen and other central leaders.

Wen Desi first congratulated them, and then asked Dean Wang of the 33rd Branch, who was the commander-in-chief, "Dean Wang, when is Taibai 2 going to be launched?"

Taibai-2 is actually an alternate satellite, exactly the same as Taibai-1. That is to say, for this launch, Dongfeng Base has prepared two rockets and two satellites, if the Taibai No. 1 launch fails, then the Taibai No. 2 will be launched to fill the position, in short, the launch must be guaranteed to be successful.

Dean Wang replied with a smile on his face: "Mr. Wen, we think that since the Taibai No. 1 was successfully launched, then the Taibai No. 2 does not need to be in such a hurry. We plan to collect more information on the operation of Taibai-1 and then launch Taibai-2 next month. This time, I'm going to try it on a different track. ”

"Well, you're experts, and you're in charge of the specifics. Wen Deji said sternly: "However, the next batch of satellites will not be military satellites." Our space program is not just for purely military purposes. Its cost is too high, and it must be profitable in the long run. I've told you before that scientists have to work with companies to help them reap the benefits and get their own research funding. This will not only benefit humanity, but also allow scientific research to be adequately funded. The greatest benefit of the space program is to launch all kinds of satellites with economic value, such as communication satellites, navigation satellites, meteorological satellites that provide meteorological forecasting services, and reconnaissance and photographic satellites that can carry out telemetry. ”

Then he turned to Rao Jiaren and said, "Director Rao, you have made a lot of contributions to the rocket team this time. In terms of rockets, I also ask you to continue to work hard and try to reduce costs as much as possible, so that there is a chance to launch in large quantities. ”

"Yes, Mr. Wen, I promise to complete the task......" Rao Jiaren saw the idol talking cordially with him, and he was so excited that he couldn't help but nod vigorously.

"Mr. Wen, our missiles can also be used," he hurriedly reported as if offering a treasure.

Wen Desi said with a smile: "I know, I also know about your missiles, and now you still use liquid rocket engines, right? Military weapons should be simple and easy to use and easy to maintain." Liquid rocket engines are inferior to solid engines in this regard, so I hope that you will continue your efforts to develop missiles with solid engines. And the current missiles are not very mature, and the cost is relatively high, which is also important. ”

Rao Jiaren hurriedly agreed: "Yes, Mr. Wen, we will continue to work hard......"

In fact, now Wen Desi is not very interested in this kind of primary primitive missile, this kind of thing with similar performance and 2 is really worthless, he is more interested in satellites.

Speaking of which, in fact, Nazi Germany in the original time and space could have launched satellites into space, and their main rocket was 2 heavy 2. 6 tons, the maximum launch height can reach 2-90 km, while the maximum end speed reaches 6 km / s. And how much is a 2? In the early stage of mass production, it was 100,000 Reichsmarks, and later it was reduced to 60,000 Reichsmarks, which were about 40,000 and 20,000 U.S. dollars respectively, and Germany made more than 5,000 pieces.

Of course, the terminal velocity of 2 is still 6 times different from the first cosmic velocity, but as long as 2 is magnified by three to five times, the satellite can be put into orbit. The rocket of the American Mercury program in the original time and space weighs only 2 tons, and it can hit small satellites into orbit. It's just that Nazi Germany wants weapons that can be used immediately, and they don't know anything about satellites, so they didn't click on this tech tree. However, later generations were well aware of the important military, technological and economic role of satellites.
