On the eve of the anti-eagle movement: the country urgently called me back home!

Qian Lao was a little surprised.

Jiang Chen took out the appointment letter:”Based on the current situation on the peninsula, in order to increase the speed of missile and aerospace related research, the headquarters decided to set up the Fifth Research Institute to be responsible for it. At the same time, Jiang Chen was appointed as the director of the institute and Qian Xuehua as the deputy director… Special order of the Military Commission, Ministry of National Defense/Chinese Academy of Sciences! June 12, 1951.”

Qian Lao was flattered:”Thank you for the organization’s trust in me. I will definitely devote my life’s learning to the institute.”

The Fifth Academy of the Ministry of National Defense currently has only one branch, the Launch Vehicle Technology Research Institute, located in Nanyuan.

A total of 8 research laboratories have been established: the first research laboratory is the overall design laboratory, the second research laboratory is the structural strength research laboratory, the third research laboratory is the aerodynamic research laboratory, the fourth research laboratory is the rocket engine research laboratory, the fifth research laboratory is the ramjet engine research laboratory, the sixth research laboratory is the chemical propellant research laboratory, the seventh research laboratory is the material research laboratory, and the eighth research laboratory is the test research laboratory.

Qian Lao looked at the establishment and research topics of the Fifth Research Institute, and his whole expression was stunned.

Space missile research?

There are no missiles yet?

It’s already started to study aerospace technology?

Qian Lao’s cognition was refreshed again by an appointment letter.

According to the course of history, in 1903, Tsiolkovsky published the world’s first theoretical work on jet motion,”Study of Space by Jet Tools”, and proposed the concept and schematic diagram of liquid propellant rockets.

After the October Revolution, Tsiolkovsky proved that multi-stage rockets could overcome the earth’s gravity and enter space, and proposed the first cosmic speed orbiting the earth’s surface, the second cosmic speed out of the earth’s gravitational field, and the third cosmic speed out of the solar system’s gravitational field.

In 1923, Hans Cat’s Oberth published”Rockets to Interplanetary Space”, proposed the theoretical formula for space rocket ignition, established the following relationships between fuel consumption, gas consumption rate, rocket speed, gravity effect during the launch phase, flight duration and flight distance, and used mathematics to explain how rockets can obtain the speed to escape the earth’s gravity. On

March 16, 1926, Eagle Sauce’s Goddard launched the world’s first liquid rocket.

In 1942 (World War I), Hans Cat developed?A-410 rocket (i.e. V-2 rocket), and was successfully launched in October of the same year.

In August 1957, the Russians successfully launched their first intercontinental missile (a long-range ballistic missile with a range of more than 8,000 kilometers). The Soviets called the Russians’ intercontinental missile”Old Seven” and NATO codenamed it”Old Seven”.?SS-6??P-7? type ballistic missile.

Then on December 17, 1957, Eagle sauce successfully tested the world’s second Atmospheric God intercontinental ballistic missile.

It was not until October 1957 that the bear launched the first artificial earth satellite with the”Satellite” carrier rocket.

So at this stage, few countries in the world have missile technology, and all theories remain at the theoretical stage.

Because, at this time, no country has proposed to develop aerospace technology, and even missile technology is not mature.

Rabbit has already proposed to develop aerospace technology?

Even Eagle sauce has just started to study missiles. Although he has a fast development speed, he lacks foresight.

Gan Lao has to admire Jiang Chen’s strategic vision and foresight for proposing this plan.

Excited, excited, trembling.

Unconsciously, Gan Lao’s blood has been boiling.

For him, it is better to study missiles than to make nuclear bombs… After all, once the satellite is successfully developed, it will benefit all mankind. However

, in Gan Lao’s view, it is very difficult to reach the first cosmic speed, let alone the second cosmic speed.

The first cosmic velocity is about 7.9 km/s, the second cosmic velocity is about 11.2 km/s, and the third cosmic velocity is about 16.7 km/s.

According to Tsiolkovsky’s theory, when the speed reaches the first cosmic velocity, the satellite will orbit the earth forever and will not fall from the sky. The first cosmic velocity is the maximum speed of an artificial satellite orbiting the earth in uniform circular motion, and it is also the speed of a near-earth satellite orbiting the earth in uniform circular motion.

If the second cosmic velocity is reached, the object will escape the bondage of the earth and fly into interstellar space, which is called the escape velocity.

If you want to travel outside the solar system, you must reach the third cosmic velocity, which is the minimum speed for an object to escape from the solar system.

Jiang Chen:”Brother Qian, although you are the vice president, you are still in charge of the Fifth Research Institute. Research topics, solve technical problems, personnel construction, etc. The task is very arduous!”

Brother Qian:”Jiang Chen, this aerospace development plan makes my eyes light up, but if we want to develop the aerospace industry, we should first solve the problems of missile technology, such as solid engines… guidance technology… aerodynamic layout technology, etc.!”

Jiang Chen:”Brother Qian, come with me……”

“Where to go?”

“Go to 101 Arsenal……”After saying that, Jiang Chen walked in front.

Gan Lao chased after him and said,”Jiang Chen, did you listen to me?���

“Jiang Chen, don’t walk so fast!”

“I’m telling you… Missiles!!”

The group boarded the plane, and along the way, Gan Lao chased Jiang Chen and talked about how to make missiles, etc.

……

101 Arsenal.

Zhao Tianming and Qiu Siyan are installing the drawings given by Jiang Chen, and are working hard to conquer the centrifuge.

At the same time, because the centrifuge must have the characteristics of high vacuum, high speed, strong corrosion, high Mach number, long life, and non-repairability.

Under normal circumstances, the centrifuge can reach tens of thousands of revolutions per minute and hundreds of thousands of revolutions, and needs to run continuously for more than ten years without stopping or maintenance.

This high speed requirement is because uranium enrichment is a high-precision technology that needs to overcome many difficulties, such as the centrifuge speed must reach tens of thousands of revolutions per minute and hundreds of thousands of revolutions per minute, and the working medium is highly corrosive uranium hexafluoride.

In addition, the speed of the centrifuge is also affected by its internal structure, working medium, load size and other factors.

Therefore, in terms of materials, Qiu Siyan can be said to have taken great pains to find a suitable one.

Finally, after consulting Jiang Chen, it was decided that stainless steel, polycarbonate, ceramic and other materials could be used.

Stainless steel has excellent corrosion resistance, high temperature acid and alkali resistance, and high hardness.

Polycarbonate plastic has good corrosion resistance and flame retardancy, as well as good mechanical properties and stability, and is not easy to deform or age.

It can also be made of alumina ceramics or silicon carbide ceramics, which have good wear resistance, corrosion resistance and high temperature strength, and are suitable for some high-strength and high-speed separation processes.

It can be said that there are many types of materials for manufacturing centrifuges, and the selection of centrifuges of different materials should be based on specific application scenarios to ensure that the centrifuge can operate stably and efficiently.

Of course, this requires Zhao Tianming and Qiu Siyan to choose according to the characteristics.

“Just choose alumina ceramics!”

“OK, I will arrange for Anshan Iron and Steel to start production immediately.……”Qiu Siyan:”By the way, how is the accessory mold going?”

“This thing has too many accessories, and they are all brand new, so the mold is still in the process of being made. It will probably be almost done after the raw materials are produced!”

“Good!” Qiu Siyan:”I heard that Jiang Chen is coming back today, right? ?”

“Well, by noon…we have completed all the tasks assigned by the factory manager. At least we have given our instructions.”

“”It’s almost time. Let’s go to the airport to pick up the factory director!”

Then, the two took the extended version of the Hongqi car to Shenyang Airport.

After getting off the car and waiting for a while, Jiang Chen’s private plane landed. The first to get off the plane were the personal bodyguard Yang Hucheng and others. After confirming that the airport was safe,

Jiang Chen, Gan Lao, Yang Siruo and others got off the plane one by one.

“Factory Director……”

“”Jiang Chen!” Qiu Siyan waved her hands and shouted. It felt like a long time since they last saw each other. However, when she saw Jiang Chen holding Yang Siruo’s hand, her excited heart was instantly poured with cold water.

“Why are you here?” Jiang Chen came to Qiu Siyan’s side and said,”Siyan, you look beautiful again after not seeing you for a few days!”

“”Hmph!” Qiu Siyan said in a bad temper.

Jiang Chen introduced:”Come here, let me introduce you to everyone. This is Gan Lao, a top professor in the military industry, who just returned to China!””

“Hello, Mr. Gan!” Zhao Tianming and Qiu Siyan greeted warmly

“”Okay, let’s go!” The group got on the extended version of the Hongqi sedan and left the airport under the escort of the motorcade. (To read the exciting novels, go to Faloo Novel Network!)

As soon as they got in the car, Gan Lao was amazed by the interior of the extended version of the Hongqi sedan in front of him.

“Jiang Chen, this car is more advanced than the one in the Eagle Sauce… I am not dreaming, am I?”

The interior is luxurious, high-end, full of Chinese elements, and air-conditioning. The touch and visual impact are all eye-catching.

“I wonder which country can produce such an amazing car? Is it Hans the cat or the Gallic rooster?”

“This is our own production.……”Zhao Tianming said as if it was normal:”Our commander-in-chief and the Ministry of Foreign Affairs are all using cars produced by the Shenyang Automobile Factory.……”[]

Shocked!

Qian Lao showed a surprised expression. Is our automobile industry technology so advanced?

Can such a good car be made?

However, just when Qian Lao was a little bit unbelieving, the convoy had passed the most prosperous street in Shenyang.

Looking at the hustle and bustle of traffic and the sea of people, all the sights are high-rise buildings and cars everywhere.

The vendors are shouting, the people live and work in peace and contentment, shopping, and everyone has a happy smile.

Such prosperity shocked Qian Lao.

At this moment, he may know what supports the rabbit soldiers on the battlefield of the peninsula.

The people have faith, the country has strength, and the nation has hope…

This is the living conditions that Qian Lao dreams of giving to the people of the motherland through his knowledge.

“Shenyang is even more prosperous than New York……”

At this moment, Gan Lao recalled the scene of Li Hongzhang’s visit to Yingjiang: In the summer of the late 19th century, when Li Hongzhang’s ship slowly entered the New York Harbor, an unprecedented scene unfolded before his eyes.

Far away from the classical European architecture, the skyline here was cut by skyscrapers, towering into the clouds, challenging the limits of the sky.

The steel structures and glass curtain walls of these high-rise buildings reflected dazzling light in the sun, and each of them demonstrated the brilliant achievements of engineering technology and architectural art.

In the center of New York City, Li Hongzhang was taken to a newly built skyscraper, which has become a new landmark of the city. With more than 20 floors, it was one of the tallest buildings in the world at that time.

He was invited to take the elevator directly to the top floor. The speed and stability of the elevator were impressive. Standing on the observation deck on the top floor…

Li Hongzhang could overlook the entire New York City. From here, he could clearly see the outline of New York Harbor and the Statue of Liberty in the distance…

He was filled with emotion! Shocked!

At this time, the prosperous Shenyang, isn’t it the appearance of New York that Li Hongzhang wanted to turn the entire Chinese land into?

If Li Hongzhang saw Shenyang at this time, he would be pleased.

The car stopped steadily in front of the 101 Arsenal

“We are here!”

After getting off the car, Gan Lao was once again���The 000 Arsenal was shocked

“This, is this the 101 Arsenal?”

It’s totally different from what I imagined.

Jiang Chen:”Brother Qian, please come in.……”

Entering the arsenal, the first thing that caught my eye was the rifle production workshop.

A buzzing sound attracted Qian Lao’s attention:”What is this?”

Zhao Tianming introduced:”Qian Lao, this is the rifle production workshop. The rifles used by the rabbit soldiers in the Peninsula Campaign were all produced here.……”

Qian Lao walked into the workshop curiously.

It was an integrated production, almost fully automated workshop. The moment the Type 49 and Type 51 automatic rifles came off the production line,

Qian Lao was stunned!

“Is this the automatic rifle we fired?”Qian Lao picked up the rifle and looked at it carefully. He was amazed by the precision and ingenious ergonomic design of the Type 49 rifle.

The degree of industrialization is too high.

It is all automated.

“Unexpectedly, our craftsmanship can reach world-class……”

Zhao Tianming:”Brother Qian, these are nothing, they are all outdated products… Now, we mainly produce the Type 51 rifle, which is the peak design of our factory director.……”

“Jiang Chen, did you design this?” Gan Lao asked while looking at the Type 51 rifle:”This rifle is cleverly designed, it is completely designed according to the height and characteristics of the rabbit soldiers… Jiang Chen, you are really a genius!!”

Jiang Chen:”I can’t say I’m a genius, but the Peninsula War broke out, and I had no choice but to develop a random rifle… It was all developed in a hurry and is not worth mentioning.……”

Jiang Chen hopes to develop the Type 95, but he just doesn’t have the time now.

Qian Lao:”You are too modest… Let’s put it this way, your rifle production and design are already ahead of the world level.……”

“I thought we were still at the stage of international production… Unexpectedly, we have already completed the standard rifle……”Gan Lao picked up the Type 49 rifle and said,”Moreover, you have set a precedent for the miniaturization of light weapons… In the future, other countries will surely imitate you.……”

Jiang Chen:”Brother Qian, stop praising me. Come on, let’s go.……”

“”Okay!”

However, after walking a few steps, Jiang Chen was attracted by the scene in front of him again.

Seeing Jiang Chen’s curiosity like Granny Liu entering the Grand View Garden, Jiang Chen was speechless.”

Jiang Lao, I just want to take you to see the Dongfeng missile… Is it that difficult?”

…… ps: Everyone, do you still have monthly tickets? I have completed the daily update of four chapters, and the next step is to add more chapters. 4 monthly tickets will add one more chapter!! (I am really sorry, my boss at work has been watching me very closely recently. I wanted to finish the extra chapter at work, but I really have no choice. However, tomorrow is Saturday, so I can add more chapters!!)
