The Sino-Japanese combined fleet was almost defeated by the Italian Air Force, and even Yang Rui was very different about it. Didn't the Italian army say that it was very face-to-face, why didn't it face this time? And he fought well, his own side was a little worse, no, he had already taken it, if it wasn't for Zhu Tiansen's temporary disposal, I am afraid that the loss would not be just 29 fighters.

"What's going on again?" Wang Jitong, who was introducing the situation of the rocket laboratory, asked. At this time, the two of them were not in Tonghua, but in Yang Rui's other fiefdom, Sakhalin Island, a narrow island of nearly 80,000 square kilometers, all of which belonged to him, and the reason why he asked for this place was not really for fishing.

"There's something going on in the Navy, but it's okay now." Yang Rui did not tell Wang Jitong the truth in detail, and there was no need to say in detail, Wang Jitong was not interested in naval operations. He returned the telegram to Pei Shoutong, who had come with him, turned his mind back to the present, and said, "You better go on, I'll stay here for three hours." ”

Sakhalin Island is more than 900 kilometers long from north to south, and it is sparsely populated and self-contained, and there is no better place to use it as a rocket launch site than this fiefdom of the Renaissance Society, so the rocket laboratory is located on Sakhalin Island.

“…… The meeting to be held will mainly report on the current situation of rocket research and development, which is mainly divided into two project groups, which are also divided according to your requirements, one is a vertical take-off and landing rocket, and the other is what you call a cruise rocket. Although the laboratory is divided into groups, in fact, many groups within the project team are shared, such as fuel, electromechanical, navigation, and propulsion. The person in charge of the laboratory is Qian Changzuo, a native of Changshu, Jiangsu, who first studied at MIT. Then he went to the University of Berlin in Germany.

When I set out to set out to set up this lab ten years ago, I brought him back. At that time, there was no rocket talent compared to now. There are only a few people in the grass platform team. However, there are also advantages to fewer people, at least it is easy to settle down here......"

After the economic reform ten years ago, except for the atomic bomb laboratory, which was still funded by the government, the other laboratories were all supported by Tianzihao funds. Fortunately, these laboratories did not spend much money in the early stage, and more than 830 tons of gold were smuggled from the United States three years ago, and because the Chinese dollar depreciated by 40 percent along with the dollar, these 830 tons of gold were used as reserves. If half is redeemed, 3.6 billion Chinese dollar bills can also be issued, and in addition to the more than 700 million US dollars spent on smuggling operations, the remaining 2.2 billion Chinese dollars is a huge amount of money that can be used at will.

However, to do so, it is necessary to rely on the National Bank to strategize and realize the additional issuance; At the same time, this is also due to the fact that China's foreign trade has been in a state of surplus, and the State Bank can exchange the newly printed Chinese dollars into US dollars in the hands of traders, and in two years it will fill the foreign exchange gap of more than 600 million US dollars spent on exchanging gold in the United States, otherwise the more than 600 million US dollars can only be obtained by selling gold, so that there are only more than 400 million Chinese dollars of gold left in their hands, and even if they issue Chinese dollars, they will only be more than 800 million.

Wang Jitong has always been in charge of spending money and not making money. As long as there is money in the account, he can manage the laboratory according to the plan and increase the laboratory funds in order to reap the results as soon as possible. Of the six most important in the laboratory under his jurisdiction, only rockets and jet engines are the toughest. Until now, there has been no clear result, and this time Yang Rui temporarily decided to go to Japan but wanted to make a detour to Sakhalin Island to visit, and he had to reluctantly arrange this report.

The list of key personnel in the laboratory is in Yang Rui's hands. In addition to Qian Changzuo, the general person in charge of Wang Jitong, there are also some laboratory backbones. Most of them have German backgrounds, and many of them are from the same school. But what surprised Yang Rui the most was that there were actually two women among them. One is Wang Jiyu, a doctor of chemistry, and then Lu Shijia, a doctor of fluid mechanics.

"This Wang Jiyu is ......" Yang Rui looked at the photo and felt that this person was very similar to Wang Jitong.

"It's my sister." Wang Jitong nodded and replied, he was surprised by Yang Rui's surprise. "Haven't you seen it?"

"Hmm. Oh. Yang Rui has seen it, but he has too many sisters, and he can't figure out who is who.

"Originally, I was ready to promise you the ...... back then," Wang Jitong said with a smile.

"Hehe, isn't it also a family member now." Yang Rui was a little embarrassed, he said that his in-laws were his son marrying Wang Jitong's granddaughter, and in terms of generation, he was a generation lower than Wang Jitong, and this relative was very uncomfortable. Fortunately, he said that the person in charge of the laboratory over there came, probably because of work needs, and the people who came were all dressed in short shirts, led by Qian Changzuo, a man with glasses.

"You're going to be excused!" Yang Rui waved his hand before they saluted, and at this time he was dressed up according to the standard set by the Ministry of Rites, dressed in a Chinese-style duke dress, with a jade pendant and a sword around his waist - he left for Japan in the afternoon, and saw that the little devil could not be cheapened, so he was dressed like this. "I'm here first, and I'm here to see you, after all, I've been suffering for several years; The second is to understand the progress of the project and listen to your opinions and ideas......"

Among the seven or eight people who came, even women felt a little unkempt, seeing this scene, Yang Rui did not agitate with great fanfare, but wanted to hear the voices of these people.

"Thank you, sir!" Yang Rui said so kindly, but the leader Qian Changzuo was still a little apprehensive, he said: "Changzuo really has a heavy trust......

"That's it! Don't say anything about this kind of discouragement. Yang Rui immediately waved his hand to stop him. You've done something that has never been done before, and I'm very satisfied with how far you have been in a few years. The reason why it is not up to the requirements may be due to the high requirements, the times are always limited, and it is difficult for people's efforts to surpass the times in which they live, and the same is true for scientific research. If it really doesn't work, then treat the rocket project as basic research and prepare for the future. ”

Because the Shanghai Film Company made a meteorite hitting the earth, and the film companies of various countries followed suit, everyone in Rocket Lab more or less had a cosmic dream, and they all fantasized about seeing human beings walk out of the earth in their lifetime. At this time, when they heard Yang Rui say that they would treat the rocket project as basic research, they were suddenly a little disappointed.

Wang Jitong's sister Wang Jiyu saw her brother by her side, and immediately said, "My lord, Team Leader Qian is polite. Rocket Lab has achieved some results over the years. At a minimum, liquid fuels solve the problem of nitrous tetroxide/dimethylhydrazine production and use. Solid fuelWe have also found a suitable binder, and we are a big step closer to the available solid fuel for rockets. The successful development of rockets for the army is also inseparable from this. ”

After all, Wang Jiyu is the Huang generation and the Taimei Party, although she is only responsible for fuel, she can decide many things in the laboratory. Her such a straightforward performance only made Wang Jitong laugh, the formula of liquid fuel was actually ordered by Yang Rui, and what Wang Jiyu did was just to achieve it, and the laboratory wanted to give up when the fuel was found to be highly toxic, but in the end it persevered. Now his sister treats Yang Rui as a person who knows nothing, which really makes him funny.

Unlike Wang Jitong's laughter, Yang Rui nodded solemnly. Although the recipe for liquid rocket fuel was copied from a chemistry book. The shape of the rocket is also copied from the book, but he lightly strokes, and there are not many things that the researcher has spent ten years on. He interrupted Wang Jitong's laughter and said: "The achievements are to be commended, but the project is kept secret, and we can only wait for the reward for meritorious deeds in the coming day." He turned his head to look at Wang Jitong and asked seriously: "Has the bonus of the project been paid?" ”

"It's been sent a long time ago." When Wang Jitong heard about the bonus, he wanted to laugh again, "At that time, it was said that the island was too cold. Therefore, the reward is the half-moon tour of Hainan and Miluo for the entire project team, plus bonuses. After he said that, he looked at Wang Jiyu again and blamed: "You are the best treatment and the most reward." He said two sentences to his sister here, and seeing that Yang Rui was still waiting, he returned to the topic. said: "Xin Jue, let's talk about it." To be concise, adults stay here for a few hours and leave. ”

"Yes." While Wang Jiyu was talking. Qian Changzuo had already grasped the general proportion, and his expression calmed down. He said, "Your Excellency." Although the laboratory is two projects, in fact, the two projects are designed to interdisciplinary in a large number of disciplines. And we have a limited number of people to use, so the people from the two project teams are grouped together.

For cruise rockets, because the impulse jet engine is extremely simple, we finalized the engine very early. Based on the characteristics of the impulse engine that cannot fly at an altitude of more than 3,000 meters, the fuel we used for the cruise rocket is gasoline, and the aerodynamic design of the shape is also leaning on the aircraft, but because the vibration of the engine will cause the failure of the rocket itself, considering that the rocket can only be ejected and launched, so in the end we have to install the engine in the rear of the rocket......"

Although he was not prepared, and Qian Changzuo did not bring any information, he still sketched the shape of the cruise rocket on a blank piece of paper - the German V1 missile. It seems that the designs are all the same, and because the engine vibrates too much, and the rocket needs to be ejected to a certain speed to work on its own, the laboratory aeropneumatic team finally chose the appearance of the historical V1 missile.

"After several years of experiments, the reliability of the rocket itself is no longer a fatal problem, even if it is ejected, we have thought of many ways to improve and simplify it, and now we only need an orbit 21 meters long and an angle of 6.5 points to launch. With 1,200 liters of gasoline on it, the rocket can fly 580 kilometers at a speed of 580 kilometers per hour and carry a 600-kilogram warhead. Qian Changzuo said the parameters of the cruise rocket, which is not as good as the V1 of the Germans, except for the range. But the problem is that the cruise rocket is an unmanned aircraft, and its sailing range is proportional to the fuel, as long as the balance of the rocket is not disrupted, adding fuel can solve the range problem.

"It's too slow!" Yang Rui heard that the speed of the rocket was less than 600 kilometers, didn't this mean that a faster plane could shoot them down. "The warhead is too light," he said, picking on another fault.

"Yes, sir." Qian Changzuo agreed, understanding that cruise rockets were used in the military, although the development plan called for the development of a target aircraft that could be used by the Air Force for target shooting. "We have already begun to solve the problem of speed, and the reason why it is too slow is also due to the use of low-grade gasoline used in automobiles, if high-grade gasoline is used, the thrust of the new engine has increased to 4.6 thousand N, an increase of nearly half compared with the previous one, and the flight speed can be close to 800 kilometers per hour based on the full load weight of the rocket of 2,500 kilograms."

"Can it be any faster?" Yang Rui asked, he didn't know how fast the V1 missile was, but he knew that one Mach was equal to 1,220 kilometers per hour. If the speed of a cruise rocket can reach 850 km, then it is the speed of a Tomahawk cruise missile.

"It's hard." Qian Changzuo shook his head helplessly under Yang Rui's gaze, "Eight hundred kilometers is the theoretical maximum, and the rocket needs to be in a low-flying state." If the flight altitude is too high and the engine does not reach the design thrust, then the speed is only about seven hundred and fifty kilometers. ”

"Eight hundred is eight hundred." Yang Rui is not worried about the altitude at all, cruise rockets have always flown at an altitude of tens of meters, and it is simply not necessary to fly at an altitude of several thousand meters. "So what's the main problem now?"

"The main thing is that you can't control it remotely." Qian Changzuo said: "We can roughly control the flight attitude of the rocket, but the rocket needs more accurate gyroscopes and accelerometers, and no one knows where it will fly." ”

It's gyroscope again! Yang Rui glanced at Wang Jitong, a few years ago, that Chen Se, reported that he could do what kind of laser gyroscope, he and Wang Jitong had high hopes, but I didn't expect things to be made, but light also has light problems, once the positive and negative two light speeds are reversed and coupled, the result is that their oscillation frequencies tend to be synchronized, and lower angular velocities cannot be measured, and their accuracy is an order of magnitude worse than that of the current mechanical gyroscope.

"Isn't radio navigation good?" Yang Rui turned his head and asked Qian Changzuo, every time he thought that he could make a copycat version of the Tomahawk cruise missile, his heart was hot, and he had made up his mind early on to build this big killer even if it cost hundreds of millions. I don't know that Qian Xuesen, the great god of later generations, once said: "The sum of these problems about structure, aerodynamics, and propulsion is only 20% of the entire missile design problem, and the remaining 80% is completely a control problem." ’

"We tried before, but one time during the experiment, because the people who lived on the island turned on the radio, they flew a rocket and crashed uncontrollably." Qian Changzuo said that he unconsciously touched a handful of sweat, that time was really dangerous.

"Where's the radar?" Yang Rui asked another way to navigate.

"Adult ......," said Wang Chenghuang, deputy head of the laboratory, "The project proposal should be cheap, and if radar is used, then the cost of the rocket will exceed expectations." Besides, the radar can only track the existing target, and cannot make the rocket fly towards the destination. ”

"That's just as well." Yang Rui had to nod, feeling that the missile was really difficult to guide. After lighting a cigarette, he looked at Wang Jitong again: "It seems that the optical laboratory and the computer laboratory still have to work harder!" (To be continued.) )
