The Iron and Steel Frenzy of the Republic of China

The s1-type sounding rocket is the largest rocket they have produced so far, with a total weight of nearly 2 tons and two upper and lower stages.The lower stage is a double-base liquid propeller, which mainly uses hydrogen peroxide and kerosene as fuel to drive the liquid oxygen kerosene engine to work under extremely high pressure and temperature, providing strong power and ensuring that the rocket can take off at a very high speed.

The upper stage is a solid propellant motor.The entire rocket shell is mainly made of non-magnetic ultra-light and high-strength aluminum alloy forging, and the outer layer is covered with high-temperature-resistant basalt fiber. Accurate and reliable.

The internal key components, the combustion chamber and the nozzle, one needs to withstand a high pressure of up to 102 ~ 2x107 Pa, and the other needs to withstand a high temperature of 2500-364 degrees, which is considered by most countries in the world They are all huge bottlenecks that are difficult to realize. At most, the Germans, Soviet Russia, and Americans can barely make do with them. But if you want to make them big enough to make the engine work long enough and stable enough, then only Zhu Bin has it. Assure.

There are so many scientists from all over the world, and Zhu Bin is using the guise of "world peace". Of course, he can't develop weapons all the time. He deliberately divides people into two main groups. One group is in charge of solid motors. He completed the research on bazookas, rockets, bazookas and primary missiles, and finally deduced it to sounding rockets with a large enough size--it's not that he didn't do it in the early stage, but those single-stage solid propeller soundings with a diameter of less than 300mm The flying height of the rocket is limited, and it is difficult to exceed [-] kilometers, which is far from enough for them to complete the research needs of atmospheric physics, space physics, astrophysics, meteorology, optics, electromagnetics and so on.

Another group, on the basis of the former, first successfully developed a relatively safe torpedo.In terms of internal structure, the advanced torpedo is actually the prototype of a rocket. Except for the need to convert chemical energy into electrical energy or mechanical energy, and finally complete the propulsion by the propeller. Chapter 364 Sounding rocket ([-]), other high-strength The pressure shell, warhead, guidance section, combustion chamber, propellant arrangement, etc. are all similar.If the biggest difference is that in terms of aerodynamic layout, one follows fluid mechanics, and the other follows a little more aerodynamics. Even torpedoes are more complicated than simple rockets in some technical aspects.

It can be said.Any country that can manufacture excellent torpedoes has no problems technically in manufacturing rockets. Conversely, countries that can manufacture rockets may not be able to make good torpedoes.

After the success of the torpedo, it was logical to start working on larger-scale gadgets, and the materials such as liquid propellants, combustion chambers, engines, nozzles, shells, etc. were almost completed, and various top instrument components of the rocket were also developed with world-class technology. After the development team is in place, the product is quickly produced.Sounding rockets that can really carry out scientific experiments will naturally come out.

Based on the mature main structure, technology and propulsion system, the entire rocket development team has hardly taken any detours, and many aerodynamic layout problems have been repeatedly verified on the rocket.

The internal instrument part was originally a very bottleneck, but Zhu Bin solved all the key technologies here.The miniature large-scale integrated circuit chips and transistors manufactured by the fully automatic production line, and the electronic boards manufactured by the basic components of high-quality capacitors and resistors are only one percent of the current world's electronic technology level products, which greatly saves space; ultra-high precision High-degree CNC machine tools and even three-dimensional printers make all small structures and finely processed parts possible; molecular melting furnaces can provide the purest materials in the world.To ensure the stable and precise performance of sensitive devices; and the unlimited material formula that can be combined arbitrarily ensures that every scientist can find the type of material that suits his heart.

Coupled with the fixed-point computing terminal mastered by a special person, the simulated wind tunnel, the low-altitude environment data below 3 meters provided by airships and large aircraft, and the atmospheric environment carried by small helium balloons that can directly fly to areas with thin air at an altitude of [-] meters , and almost unlimited financial support, thousands of experts and experimental groups can't come up with anything good.Don't you have to commit suicide in shame!

It can be said that the s1 sounding rocket in front of us has actually concentrated the culmination of rocket technology in the world today, and it can be used as a stable experimental platform and weapon development basis.But...Zhu Bin is not going to let everyone know.

For the sake of security and confidentiality, the entire project has been dismantled into pieces, and every key technical part is presided over or participated by Chinese local scientists, in order to prevent anyone who knows too much from taking it out. It will cause unmanageable big trouble!

Although every expert who participated in these core projects has signed a work agreement of no less than ten years and a lifetime confidentiality agreement, it can be found in this chaotic era.It's better to be more careful.

After von Braun came to [China], he really participated in rocket research for less than a year and a half.The achievements were mainly concentrated in the last year. Since the gathering of scientists from all over the world in June last year, the project has advanced by leaps and bounds. Naturally, his scope of work has been limited. He mainly focuses on rocket design, which is actually the most critical part.

Right now, the payload on the top of this rocket, which he designed with a lot of effort, can reach a maximum of 235 kilograms, and the design flight altitude can reach 200 kilometers, which is already quite excellent!

After Shu Xingbei finished shouting, the last situation report from all parties quickly came over the radio: "The rocket inspection is complete, and the staff is evacuated!"

"The launch site is cleared, and the security personnel are evacuated!"

"The Wuzhishan observation station is ready to be put in place, and the radar is working normally!"

"Ocean One survey ship is ready and the radar is working properly!"

"Jiantian No. [-] is working normally!"

"The main control system of the command center is working normally!"

...The strict working procedures were meticulous, and the reports from more than a dozen units came one after another. They were deliberately erected on a large LED electronic clock in front, and the huge Arabic numerals jumped steadily and counted down.

"Countdown 1 minute!"

The loud time chime made von Braun tremble again, and he subconsciously put his hand on the mushroom-shaped red button, and Shu Xingbei quickly grabbed it for him, laughing and saying, "Don't be so stupid, kid!" Excited, watch out for fire!"

Von Braun smiled shyly, and subconsciously turned his head to look at Zhu Bin and those sitting behind him, seeing him smiling and looking at him encouragingly, he felt certain in his heart, took a deep breath, and listened to the countdown. : "Six, five, four, three, two, one! Shoot!"

Shu Xingbei's broad and thick bear paws were placed on the back of his hand with great force, and he pressed the button down heavily. Outside the high-transmittance Xuan window, a billowing thick smoke from the shooting field in the distance swept in, billowed up, and fell down. For a moment, a snow-white awl-shaped rocket shot out a blazing flame of more than ten meters. Under the observation of the infrared lens, it glowed bright orange, which meant that its propellant was kerosene.

Driven by the surging high-speed flame, the two-ton arrow body pierced the sky like a sharp sword, and suddenly rushed to the sky, accelerating from zero to Mach [-] in a straight line, and rushing towards a higher speed!

The moment the rocket took off, dozens of instruments loaded on the top started to operate at the same time, and within a few seconds, all the major observation stations around the area sent reports of receiving signals one after another!

A few seconds later, the second-stage liquid propellant rocket ran out of fuel, detached from the connecting part, and fell toward the South China Sea. The first-stage solid engine ignited in time, maintaining the speed and angle and continuing to hit high altitudes!

On the ground observation station and the survey ship, the high-precision radar continuously captured the relatively small figure of the rocket, and never missed the high-altitude layers all the way to the top of the troposphere. A microwave communication link is passed to the ground station before anything else, and the altitude and status of the rocket are constantly reported.

"Seventy kilometers! Ninety kilometers! 120 kilometers! 150 kilometers! Two hundred kilometers! The solid engine stopped working... The measuring instrument was released... The radio positioning equipment is working normally, and the launch was successful!"

"Success!"

Shu Xingbei let out a loud roar, clenched his fists and swung vigorously in the air. The control center suddenly burst into cheers. Hundreds of scientists in white coats jumped up like children, warmly embraced the people next to them, and slapped each other's shoulders and backs vigorously. Back, in another temporary rest area not far away, a whole row of champagne bottles opened "bang bang"!

Although Zhu Bin has seen the tens of thousands of meters long star battleship entering service many times, and has no feeling for this kind of gadget, he is still affected by the atmosphere of the scene. He has taken a big step towards his future goal, and he smiled and applauded, walked over, shook hands with Shu Xingbei, Ye Qisun and others, and finally hugged von Braun, patted him on the shoulder and said: "What are you doing?" It's great! Congratulations!"

Braun blushed with excitement and stumbled: "I should be the one who expresses my sincerest thanks to you! Without you, I would not have achieved my wish so quickly! I would not have had the opportunity to personally create such a great history!"

Braun is only 24 years old this year. He has been immersed in the laboratory since graduation. He is a standard otaku, very innocent, and he never thought why Zhu Bin would call him and abduct him to [China].

Zhu Bin laughed secretly in his heart: "Without me, you would still make history! Great young man!" But he would never say it out of his mouth. He nodded in satisfaction, and went on to talk to other people. Warm congratulations!

This is not a successful launch in the general sense!The working and operation of the instruments and equipment carried on the rocket is enough to prove that their various guesses and calculations about the low-orbit space below 200 kilometers are correct. Next, the launch test of the living creature can be carried out, a series of experiments After all are completed, formal manned spaceflight will become a reality! ! ! !
