The S1 sounding rocket is the largest rocket they have made so far, with a total weight of nearly 2 tons and divided into two stages. The lower stage is a dual-based liquid thruster, mainly using hydrogen peroxide and kerosene as fuel to drive the liquid oxygen kerosene engine to work at extremely high pressures and temperatures, providing strong power to ensure that the rocket can take off at extremely high speeds.

The previous stage is a solid propellant engine. The entire rocket shell is mainly made of non-magnetic ultra-light and high-strength aluminum alloy forged and pressed. The outer layer is covered with high-temperature-resistant basalt fibers. The aerodynamic shape has been repeatedly simulated and calculated by the spacecraft's intelligent brain to ensure that the data calculated by a group of scientists are accurate and reliable.

The internal key components of the combustion chamber and nozzle, one needs to withstand high pressures of up to 102~2x107 Pa, and the other needs to withstand high temperatures of 25003500 degrees. This is a huge bottleneck that is difficult to achieve in most countries in the world. At most, there are Germans, Soviet Russians and Americans who can barely make do with it, but if you want to make it big enough to make the engine work long and stable enough, only Zhu Bin can guarantee it.

Zhu Bin has been fooling so many scientists from the world, and under the guise of "world peace", of course he cannot continue to develop weapons. He deliberately divided them into two main groups, one of whom was responsible for solid engines. He first completed the research on rocket launchers, rockets, rocket launchers and primary missiles for him. Finally, it was natural to deduce that sounding rockets with large enough sizes were not done in the early stage, but the flight altitude of those single-stage solid thruster sounding rockets with diameters less than 300mm was limited. It was difficult to exceed 50 kilometers. It was far from enough for them to complete the research needs of atmospheric physics, space physics, astrophysics, meteorology, optics, electromagnetics and other aspects.

The other group, based on the former, first successfully developed a relatively safe torpedo. From the internal structure, the advanced torpedo is actually the prototype of a rocket. In addition to converting chemical energy into electrical or mechanical energy, and finally completing the propulsion work by the propeller, other high-strength pressure-resistant shells, warheads, guidance units, combustion chambers, propellant arrangements, etc. are similar. If the biggest difference is, in aerodynamic layout, one follows fluid mechanics. The other follows aerodynamics a little more, and some technologies of torpedo are even more complicated than simple rockets.

It can be said that any country that can create excellent torpedoes will be technically free of charge. On the other hand, a country that can create rockets may not be able to do a good job of torpedoes.

After the success of the torpedo, it was natural to start construction of larger-sized items, and the liquid propellant, combustion chamber, engine, nozzle, shell and other materials were almost done. The rocket's various top instrument components were quickly taken out after the world-class development team was in place. The sounding rocket that can truly conduct scientific experiments naturally came out.

Based on the mature main structure, the improvement and maturity of technology and propulsion systems, the entire rocket development team has almost no detours, and many problems in aerodynamic layout have been repeatedly verified on the rocket.

The internal instrument part was originally a very bottleneck, but Zhu Bin all solved the key technologies. The electronic boards made of micro large-scale integrated circuit chips and transistors made of fully automatic production lines, and the electronic boards made of high-quality capacitor and resistor can be made only one percent of the current world electronic technology level, saving huge space; ultra-high-precision CNC machine tools and even three-dimensional printers make all small structures and fine-processed parts possible; molecular smelting furnaces can provide the world's most pure materials, ensuring stable and accurate performance of sensitive devices; and unlimited material formulas that can be combined at will ensure that every scientist can find a type of material that suits his wishes.

In addition, the fixed-point computing terminals, simulated wind tunnels, low-altitude environmental data provided by airships and large aircraft, small helium balloons can fly directly to the atmospheric environment of 30,000 meters high and atmospheric air at the same temperature, and almost unlimited financial support. Thousands of experts and experimental teams can't create some fun, so they will all commit suicide in shame!

It can be said that the S1 sounding rocket in front of us has actually concentrated the great achievements of rocket technology in today's world, and can be used as a stable experimental platform and weapon development basis, but... Zhu Bin is not going to let everyone know about it.

For the sake of security and confidentiality, the entire project was dismantled and all key technical parts were hosted or participated by Chinese local scientists, in order to prevent any one who knows too much will cause uncontrollable trouble!

Although every expert involved in these core projects has signed a work agreement and a lifelong confidentiality agreement of no less than ten years, it is better to be careful in this chaotic era.

After Von Braun came to China, he had been involved in rocket research for less than a year and a half. The results were mainly concentrated in the past year. Since scientists from all over the world gathered in June last year, the project has made rapid progress, and naturally limited his work scope. It is mainly focused on rocket design, which is actually the most critical part.

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

Shu Xingbei finished shouting, and the last report of the situation from all parties quickly came from the radio:

"The rocket inspection is completed, the staff are evacuated!"

"The launch site is cleared and safety personnel are evacuated!"

"The Wuzhishan Observation Station is ready to be in place, and the radar is working normally!"

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

"Jiantian 1 works normally!"

"The command center main control system is working properly!"

...The strict working procedures were meticulous, and more than a dozen units reported in sequence, deliberately erected on a large LED electronic clock in front of them, with huge Arabic numerals jumping steadily counting down.

"Countdown to one minute!"

The loud sound of the time made Feng Braun tremble again, and subconsciously placed his hand above the mushroom-shaped red button. Shu Xingbei's eyes quickly grabbed him with his hands, and laughed: "Don't be so excited, boy, be careful of getting angry!"

Feng Braun smiled shyly, subconsciously turned his head to look at Zhu Bin and the one sitting behind him smiling and staring at him with encouragement. He immediately felt relieved in his heart, took a deep breath, and listened to the countdown: "Six, five, four, three, two, one! Launch!"

Shu Xingbei's wide and thick bear paw was placed on the back of his hand with force, pressing the button heavily, and then he saw a high-transmittance window outside the high-transmittance window sweeping over the launch site, tumbling up. The next moment, a snow-white awl-shaped rocket ejected the blazing flames of the factory more than ten meters. Under the observation of infrared lenses, it emitted a bright orange color, indicating that its propellant was kerosene.

The two-ton arrow body pierced the sky like a sharp sword under the surging high-speed flames, and suddenly rushed into the sky, accelerating from zero straight line to Mach two, and running wildly towards a higher speed!

Just as the rocket took off, dozens of instruments loaded on the top began to operate at the same time. In a few seconds, the major observation stations around them sent reports of signal reception!

A few seconds later, the second stage of liquid propelling rocket was exhausted, separated from the connecting part and fell towards the South China Sea. The first stage of solid engine ignited in time, maintaining the speed and angle to continue to impact high altitude!

On the ground observation station and the measurement ship, high-precision radar constantly captured relatively small rocket figures, and no one was missing from the high altitude to the top of the troposphere. Finally, the helium balloon monitoring instrument at the highest point took over, and a group of data was transmitted to the ground station through microwave communication links. There was no time for anything else to be reported, and the height and status of the rocket were continuously reported.

"Seventy kilometers! Ninety kilometers! One hundred and twenty kilometers! One hundred and fifty kilometers! Two hundred and two hundred kilometers! The solid engine stops working... The measurement instrument is released... The radio positioning equipment works normally and the launch is successful!"

"Success!"

Shu Xingbei roared, clenched his fists and waved his force in the air. The control center suddenly felt thunderous. Hundreds of scientists in white coats jumped up like children, hugged the people next to him, patted each other's shoulders and backs hard. In another temporary rest area not far away, a whole row of champagne bottles opened "bang"!

Although Zhu Bin has seen the scene of the tens of thousands of meters of interstellar warships entering service, and has no feeling about this kind of gadget at all, he is still affected by the atmosphere on the scene. Besides, such success also means that he has taken a big step towards his future goal. He also smiled and applauded, walked over, shook hands with Shu Xingbei, Ye Qisun and others, and finally hugged Feng Braun, patted his shoulder and said, "It's a great job! Congratulations!"

Braun blushed with excitement and said stutteringly: "It should be my sincerest thanks to you! Without you, I would not have achieved my wish so quickly! I would not have had the opportunity to create such a great history myself!"

Braun is only 24 years old this year. He has been buried in the laboratory since graduation. He is a standard little otaku. He is very simple and has never thought about why Zhu Bin would call him to China by name.

Zhu Bin smiled in his heart: "Without me, I will create history too! Great young man!" But he would never say it out loud. He nodded with satisfaction and followed him to congratulate others warmly!

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