Without more accurate gyroscopes, miniaturized computers, no satellite ......, all of this would be a dream. However, all laboratories are moving forward in tandem, and the optics laboratory says that it has found an idea and is thinking about whether the experiment is feasible; After numerous failures, the Transistor Laboratory had solved the problem of rod growth using the Cheklauski method in 1918, but it had encountered difficulties in semiconductor doping, but unlike the previous ones, the researchers who saw hope were confident that they could optimistically estimate that the transistors would be mass-produced on a small scale five years ago.

At this point, Yang Rui has fully understood that the core of the science and technology tree is the transistor, and as long as the transistor problem is solved and used on a small scale in the military, the East Asian alliance can be invincible. After that, China's goods will not only have an advantage in quality and cost, but also a complete crushing in technical performance, and the key is to keep the last decade.

When Qian Changzuo and others were preparing materials to introduce the direct flight rocket, Yang Rui thought that this was the problem. China is about to set off the wave of the third industrial revolution, and with the first-mover advantage, she will surely dominate Asia and dominate the world. However, Xiong has just been born, the world situation is unpredictable, and it is likely that she will face extinction before she grows up, and the London naval negotiations in the second half of the year will be a real test.

Some people suggested that Japan should be abandoned, and even Wang Jitong had this idea in a casual conversation, believing that what China lacked was 10 years, and the naval disarmament treaty was precisely 10 years. There is nothing wrong with giving up Japan to gain a precious 10 years, and as long as it survives this 10 years, China will have no worries about it in the future. Wang Jitong's ideas represent the thoughts of many people who are familiar with the situation at home and abroad. For example, Yu Zixun, who has completely become the leader of Christian pastors in China, such as the representatives of the Inspectorate who don't want to fight and just want to get rich......

These people's views are insightful. But in Yang Rui's view, giving up Japan is giving up the first island chain. Although the Philippines is in the hands of the United States, because of the treaty, the west of Pearl Harbor is not within the scope of American sea power, which is why the US Navy's Asian Fleet has only two obsolete cruisers and a bunch of destroyers and submarines - they are not confident that they can hold anywhere west of Pearl Harbor after the war, and the Philippines passed the Independence Act two years ago, and will become independent ten years later, at which time, the United States will only have islands in the western Pacific to support, but even Guam. It is also too far from the Asian continent.

In this case, Japan is extremely important. Mackinder, a British political geographer who was an adviser to the government of Greater China, except for the classic saying, 'Whoever rules Eastern Europe can rule the hinterland of the continent; Whoever rules the hinterland of the continent rules the island of the world; Whoever rules the world island will be able to rule the world', there is also a prophecy: 'Whoever rules Northeast Asia will control the western Pacific; Whoever controls the Western Pacific controls the destiny of Asia. ’

Excluding the British nature of-stirring sticks, this assertion does capture the essence of Asia. China, Japan, and Russia are all entangled in the Korean Peninsula in Northeast Asia. For China, the Korean Peninsula is the arm of Gyeonggi and the barrier of the northeast. For Japan, the Korean Peninsula is a 'bayonet in the belly' -- 14 years ago, when China and Japan first talked about forming an alliance, the Japanese actually proposed to make the southern part of Korea a separate country; And to Russia. The Korean Peninsula is the horn of Vladivostok, the outlet of the Pacific Ocean, and only a pro-Russian North Korea can secure this strategic outlet to the sea, thousands of miles away from Petersburg and Moscow. It is a pity that the Petersburg Treaty eighteen years ago cost Russia Vladivostok.

Abandon Japan. Even if the Japanese do not attack Pearl Harbor, China and Japan will have more and more serious contradictions over the Korean issue. The result of the infighting must have been Japan's abandonment of Central Asia and its gradual transformation into the English and American sheepdogs of Asia. This kind of geographical loss can never be compensated for by scientific and technological gains. No matter how advanced the technology is, it must have a stable and safe foundation to thrive......

"It's a ......" Seeing that Yang Rui was silent, Wang Jitong knew that his old problem of wandering was done again, so he had to call him a few words.

"Oh......" Yang Rui woke up, he looked at Qian Changzuo and the others beside him, and said with a smile: "You're ready, right?" ”

"Yes, sir!" Qian Changzuo's side had already been prepared, the projector had already been moved, and the windows had been closed, but in order to wait for Yang Rui, the lights were still on. At this time, seeing that Yang Rui came back to his senses, he arranged for the staff to start playing the video - Yang Rui came too suddenly, so he could only play the video recorded during the rocket experiment.

The lights gradually dimmed, and under the light of the projector, there was a black and white image on the white cloth, but there was no sound. The first thing to do was a cruise rocket, like an airplane, which was carried to the launch stand by two researchers, then set the instrument parameters, add gasoline and start igniting — the rocket's engine ignited first, and then it was thrust out by a small rocket. According to the previous introduction, this impulse jet engine must work at a certain speed in order to work properly, it does not have a compressor part, and can only rely on speed to obtain relatively sufficient air, so that the engine can produce enough pressure gas inside, and these gases are all sent out from the tail of the engine to make the rocket gain thrust.

In the film, the cruise rocket starts working on its own after taking off, and the fire in the tail of the engine goes out. Guided by the radio remote control of the accompanying aircraft, it swerves, dives at a small angle or pulls up like a manned person. At this time, Yang Rui suddenly understood why the laboratory didn't speed up the rocket, five hundred and eight was the fastest speed of the twin-engine plane at this time, if the speed of the rocket was faster, it would not be possible to track the remote control.

"It's a shame." Thinking that this thing cost less than three thousand yuan, Yang Rui was extremely sorry. Such a cheap cost is really a big killer weapon for poor countries, but there is no way to control it, it seems that this Tomahawk cruise missile is really not so easy to get. He turned to look at Bei Shoutong, who was watching attentively beside him, and said, "Do you use it?" ”

When Yang Rui was distracted just now, Pei Shoutong not only communicated with Qian Changzuo and others, but also went to the laboratory to see the real thing. At this time, his face was full of regret, and he said: "If the problem of radio interference and accuracy can be solved, then it can be used regardless of the army, navy, and air force." Basically what a bomber can do. It's all inclusive. If these two issues can't be solved, I would like to ...... I can only do remote control target aircraft. Increase the air defense of the troops. ”

"You can think about it easily, if this thing can only be used as a target machine. Why set up a laboratory for research? In the dark, Yang Rui couldn't see Bei Shoutong's expression, but he could still understand the root of his thoughts-people who had never seen a precision strike by Tomahawk cruise missiles were like this.

After the first film about a cruise rocket, the next film is a direct-flying rocket, in which an open launch site is set up with a launch tower and a rocket about 15 meters high, which looks like a modern rocket. After the gas mask-clad researcher refueled, the launch procedure was prepared one by one, and after pre-firing, the rocket was up and forth in ten seconds - this time with a sound, and the thunderous roar of the rocket engine was heard. Seeing this wingless thing actually flying, and flying faster and higher, Bei Shoutong couldn't help but let out an 'ah', and his whole body shook.

What happened was only the Type C rocket, followed by the Type D rocket, which is more than 20 meters high and should be more than three meters in diameter - in the plan of the laboratory direct flight rocket project team, the rocket is a combination of Type A and Type B, and at the same time borrows from the appearance of the Long March 2 rocket copied by Yang Rui to high school physics. There will also be some small rockets tied to the bottom of these two stages as a boost.

Although the D-type rocket is five or six meters taller than the C-type and larger, it still goes up to the sky safely in the film, but the fire and sound are greater. When it was launched, the entire launch site was filled with smoke from it, and the rocket flew into the clouds thick in the middle of the shot. The film ends.

The light in the room was turned on at this time, and Qian Changzuo smiled and stepped forward and said, "My lord." The non-fly rocket is large in size and has a high engine temperature. The structure is also complex, and the success rate of launch is low. Since the test, the C rocket has been launched 21 times and successfully 8 times, and it is only now that its reliability has been finally resolved; The D-type rocket was only tested in the last three years, and it was launched nine times, and only one was successful......"

"Why are there so few launches?" Yang Rui didn't care about his failure rate, he was just surprised that the laboratory funds had always been sufficient.

"The main thing is that after each launch, we have to analyze the cause of the failure, and then make modifications to the rocket, so that each launch has two or three months to discuss where the problem is, and determine the modification method, so there are at most four launches a year, and some are five times more. The C-type rocket was completely overturned three years ago and redesigned to achieve success. Qian Changzuo said.

"After several experiments of the D-type rocket, I feel that it is not possible to copy the design of the C-type, and now we are redesigning the plan, and it is estimated that like the C-type, it will take about three to four years and 20 to 25 test launches before it can basically mature. And the E-type rocket, that is, the two types of propylene and Ding rockets are combined into one, and some boosters are added to the small fire, I am afraid it will take five years to finally succeed. The total weight of this type of rocket is more than 90 tons, and the thrust of the first stage can reach 2,500,000 NN, and the thrust of the second stage is 250,000 N......"

Yang Rui had no idea about rocket thrust, he listened carefully to a large pile of data spit out of Qian Changzuo's mouth, and after he finished speaking, he asked: "You just tell me two data, if you carry a five-ton warhead, how far can the rocket hit, and how high can it hit?" ”

The question of the five-ton warhead made Wang Jitong's eyes flicker, and Qian Changzuo gave a data after a little thought: "Theoretically, if you carry a five-ton warhead, the E-type rocket can reach a low-earth orbit of about 300 kilometers; The distance can exceed 8,000 kilometers. But my lord, the rocket was not designed to carry a five-ton warhead, and the first stage rocket may not need to be modified, but the second stage rocket will need to be greatly modified. ”

"That's for later." Hearing that the rocket can hit 8,000 kilometers, Yang Rui was a little satisfied, forgetting that this thing still needs at least ten years of experimentation, and the structure of the two-stage rocket plus the booster small rocket will definitely cause many problems.

"yes, that's something to come later." Wang Jitong said the same. He thought that it would be more than ten years before the E-type rocket was developed, and the international situation at that time would definitely not be as good as it is now, and maybe the rocket would really be used to land on the moon.

"I've read it all, I'm satisfied." Yang Rui said to the main person in charge of the laboratory, "Rocket research is of great significance, if a meteorite really hits the earth, we are really helpless without a rocket." ”

Yang Rui's words caused a burst of laughter, they had previously learned from Wang Jiyu that the rocket laboratory was the most expensive, and a test flight of the Type C rocket would cost tens of thousands of yuan, and the larger D-type would be even more incredible, with each flight being millions of yuan. Up to now, Type C can be said to be finalized, but Type D will not be stable without 20 or 30 million. And this is only the material consumption of the rocket itself, not including the salaries and other expenses of hundreds of people in the laboratory, not to mention the investment of the entire experimental site itself.

These hundreds of millions of dollars are not provided by the government, but by the private sponsorship of Tianzihao, which is the case, and whether the project is carried out depends on Yang Rui's attitude. After getting his affirmation, Qian Changzuo introduced some problems with direct rockets - still navigation control problems, and the laboratory finally even came up with a trick of astrological navigation, but it was also an unreliable design after research - it was really a difficult task to calibrate the stars on a fast-moving and vibrating rocket.

On the whole, the research and development of small computers based on transistors is becoming more and more urgent, if there is a small computer, the internal control of the rocket can be automated, and many achievements of the sensor laboratory have been used for the internal control and external monitoring of the rocket, otherwise the C rocket can not be successful so quickly, but there is no unified brain of many sensor information to analyze the information in a unified manner, and implement the optimal solution according to the program, which makes the rocket in a dry stare state that can only be monitored and difficult to adjust in real time.

There are many, many problems, the requirements are very urgent and urgent, and when the sun sets and Yang Rui and the ship leaves, everyone has endless topics. In the corridor on the side of the cruise ship, looking at the people waving on the dock, Yang Rui smiled and waved to everyone, and only when the cruise ship went away did he put down his hand and prepare to return to the cabin, at this time Bei Shoutong suddenly said, "Sir, I have an idea, I don't know if it is feasible......

Bei Shoutong was like being stupid from the moment he saw the C-type rocket take off, and it took several hours to say this sentence, and Yang Rui, who returned to the cabin, beckoned him to sit down, and said with a smile: "Do you have any new ideas?" ”

"Sir, just now Dr. Qian said that the E-type rocket can send five tons of things to low earth orbit, and said that the object in low earth orbit will not fall down immediately, it will only rotate rapidly around the earth, and slowly fall into the atmosphere after stalling?" Pei Shoutong recalled what he had just heard word by word, and his eyebrows were extremely solemn.

"Yes! If a rocket can deliver a warhead to an altitude of 36,000 kilometers, then we can launch a communications satellite, which is in a synchronous orbit, and satellites are forbidden relative to the Earth. Yang Rui said with a smile. Although he doesn't know too much, he understands better than Bei Shoutong. He also wanted to satellite, but the problem was that the solar cells in the transistor laboratory were not yet mature, and the rocket could only reach a low-earth orbit of several hundred kilometers, and in the end there was no suitable small computer.

Yang Rui, who guessed that Bei Shoutong wanted to put a satellite, looked at him and smiled, but Bei Shoutong's next sentence made him change color, only to see him make a gesture to take a picture, his eyes lit up and said: "Sir, what if we send the camera up......" (to be continued.) )
