People who can become engineers and designers, and even chief engineers of the most famous large aircraft manufacturing companies in the United States, such as Curtis, Boeing, and General Motors, now and in the future, will naturally have a high level of knowledge and vision. Not only Wang Zhu, Wang Xiaofeng, Zeng Yijing and others have the same feeling as Ba Yuzao, but other experts also have the same understanding, even Guo Wenyuan, who has just rushed over after hearing the news, is also deeply touched. They all feel that Song Zhewu's summary of "high, fast, far, heavy, spiritual, and accurate" can be called a six-character mantra.

Any aircraft with any of the advantages of this six-word mantra is a very good aircraft, and if it has all six items, it is the best aircraft in the world today.

"Commander, I heard that after graduating from the Baoding Military Academy, you went directly to the German "Dresden Military Academy" to study military affairs, is it not true that you also studied aviation in Germany?" Ba Yuzao asked suspiciously.

Indeed, it is hard to believe that a person who can have such an insightful view of the development of aviation said that he had not studied aviation. Not only Ba Yuzao, but others also believe that Song Zhewu must have carried out relevant studies.

Regarding Ba Yuzao's doubts, Song Zhewu couldn't help but smile bitterly in his heart, but he said: "Brother Yunhua, I didn't graduate from Baoding Military Academy, but dropped out, to be precise, I almost never attended class. I was sent to the ninth issue by my father in 20 years. It was the summer vacation, and I hadn't attended a day of class before the Anhui War broke out. Qu Tongfeng, the former commander-in-chief of the Anhui Army, who was the principal of the Baoding Military Academy, was captured in Songlindian, and the 15th Division of the Anhui Army surrendered to the direct army, and the military academy was used as a temporary shelter barracks by the direct troops. Because the 15th Division had been in arrears for several months, the junior officers were dissatisfied, and a mutiny broke out, and the military academy was looted and set on fire, and the military academy had to be closed. ”

"My father was afraid that I would cause trouble, so he immediately sent me to Germany to study military affairs. Although I studied military affairs in Dresden, I was very interested in scientific knowledge and scientific research in various disciplines, so I dabbled in many subjects in addition to my studies, and often took advantage of the time to go to Berlin to consult with those scholars and professors. The views on aviation that I just mentioned are just some of my experiences, and today I am a class with an axe, and if there is something missing, I would like to ask the experts to correct it. ”

Wang Zhu said with emotion: "The commander's words have won the essence of modern aviation, and the forward-looking surname is extremely strong, even if it is not an exaggeration to take it as the guiding ideology for the future development of world aviation. ”

Ba Yuzao also said sincerely: "I heard Wen Yuan say that the commander is well-read and has a strong memory, has incisive and unique insights on a variety of disciplines, and is even a pedantic man in chemical engineering. Originally, I was a little skeptical about this, but after listening to the commander's words today, I truly believe that if the commander engages in academic research, he will certainly have great achievements, and the commander is a little condescending as a soldier. ”

Song Zhewu is most afraid that others will entangle him more on how to learn this knowledge, unless it is absolutely necessary to be fully prepared with him, those who can say and those who cannot be said must be thought out in advance, otherwise he tries his best to avoid discussing academic issues with others. If he is not careful, others will ask him about the origin of his knowledge.

Song Zhewu saw that Ba Yuzao, Wang Zhu and others had this tendency now, so they were busy and pulled the topic back.

"To do this, it is not enough to rely on these aviation experts in your aviation institute, the aircraft is a system engineering, is the best integration of many technologies, it not only needs aerodynamics and other aviation knowledge, it also needs the support of material mechanics, mechanics, electronics, optics, hydraulics, remote sensing and many other disciplines. For example, as far as I know, many foreign advanced aircraft not only use metal skins, but also use a large number of metal pipes on the structural skeleton, which greatly improves the structural strength of the aircraft and provides the necessary guarantee for continuously improving the speed. ”

"However, it is not enough to just use pipes, there are some parts that require special profiles, which will be better for the structural stress of the aircraft. With the continuous improvement of speed, the requirements for the structural strength of the aircraft will be higher and higher, which requires the development of some special alloy materials with higher strength; There is also a metal skin, which is very thin, and once it is hit in an air battle, it is easy for a large piece of metal skin to fall off, causing the plane to stall and crash. Therefore, a stronger material is needed to make the shaping material of the aircraft. ”

"I think aluminum is a good choice. The aluminum shell is not only stronger than ordinary skin, but also lighter, but because the weight increase is not very much, the loss of speed is very small. But there is also a problem with using aluminum, which is that pure aluminum is not hard enough. However, I think this can be solved, steel can be added to other metals to form a stronger alloy, aluminum should also be able to, in fact, theoretically any metal can cause physical and chemical changes in its strength, toughness, conductivity, and corrosion resistance because of the formation of alloys. If we can develop a stronger alloy of aluminum, we will have the conditions to use a more powerful engine. ”

Speaking of this, Song Zhewu suddenly felt that there was a problem that he had handled inappropriately, that is, he found that he had made too obvious distinctions between various disciplines, and it was difficult for various disciplines to have the possibility of cross-collaboration. Although it is not possible to achieve the integration of various disciplines with each other, or even the emergence of new disciplines, it is at least not conducive to the coordination and integration of various disciplines.

Song Zhewu thought for a while, turned his head to Xiao Guodong and said: "Chief of Staff, I think it is a little inappropriate for us to separate the two research institutes of electronics and optics, and I suggest that these two research institutes be divided into the School of Engineering, so that it is more convenient for various disciplines to penetrate each other, and it is more conducive to the better integration of these technologies." ”

Xiao Guodong does not know much about these technical problems, but he knows Song Zhewu very well, he believes that Wang Mingyang said, "Song Zhewu must be a very outstanding scientist if he engages in scientific research", over the years, many things have happened, and many experts and scholars admire Song Zhewu is by no means unreasonable, Song Zhewu can convince these elites again and again is the best proof, he believes that all Song Zhewu's decisions in this regard are correct.

Xiao Guodong nodded in agreement and said, "Okay, that's it." It's just that Wen Yuan is going to suffer. After speaking, he smiled apologetically at Guo Wenyuan.

Song Zhewu said to Guo Wenyuan: "In your engineering school, we will also add a metal materials research room and a hydraulic transmission research room. The task of the Metal Materials Research Laboratory is to develop high-strength new materials for our aircraft. Of course, it should not be limited to aircraft, but also other military materials; Hydraulic transmission is the use of the static pressure energy of the liquid to achieve power transmission. More than 100 years ago, the hydraulic press was born in the United Kingdom, and at the beginning of this century, the hydraulic press with oil as the medium appeared. After 1920, hydraulic technology developed more rapidly. In 1925, Vickers invented the pressure balanced vane pump, which laid the foundation for the gradual establishment of modern hydraulic component industry or hydraulic transmission. Constantine. Nisco's theoretical and practical research on the transmission of energy fluctuations - hydraulic couplings, hydraulic torque converters, etc., has led to the great development of hydraulic transmission. However, this advanced technology is still blank in our country. ”

"I hope you'll try to fill that gap. Hydraulic transmission does not have a conversion node like mechanical transmission, so it runs more smoothly and faster, and the volume can also be smaller. If our aircraft could use hydraulic transmission heavily instead of mechanical transmission, our aircraft would be more flexible. ”

Song Zhewu continued: "The General Management Office and the Logistics Office of the Academy of Engineering can only be appropriately expanded, and Wen Yuan is assigned two assistants to handle general affairs, so that Wen Yuan's energy will not be too much involved." ”

Song Zhewu went on to explain: "The reason why the Institute of Optics and the Institute of Electronics are both placed in the Academy of Engineering is that we want these disciplines not only to develop independently in their own disciplines, but also to properly penetrate and integrate, give full play to their abilities more effectively, and create greater results." For example, whether some mechanical transmissions can be replaced by electric transmissions, ......"

Song Zhewu stopped the topic in time, so he didn't say the term laser rangefinder, which can cause trouble. Song Zhewu secretly blamed himself for being a little too excited today and a little open-mouthed.

In this era, not to mention the laser rangefinder, even the electric drive can only think about it, and the electric drive must be controlled with the help of easy-to-control special, servo motors, such as stepper motors, self-aligning machines, linear motors, ultrasonic motors and so on. And these special motors are basically blank in the international community, even if some have appeared, the technology is far from mature, if these things are developed by themselves, it is absolutely unrealistic. Under the existing conditions, this is nothing short of whimsical.

"Well said!" Ba Yuzao stood up excitedly and shouted loudly.

As soon as the words came out, Ba Yuzao suddenly realized that he was a little rude, Song Zhewu was not only the general of the national political axe, but also his boss.

In order to hide his embarrassment, Ba Yuzao hurriedly said: "The commander's words made Yuzao like a wake-up awakening, and the mouth suddenly opened, to develop an excellent aircraft, only an excellent aircraft designer is not enough, but also need to have the strong support of a variety of disciplines, only by organically combining these advanced technologies, can the best aircraft be developed." ”

Then he whispered to himself, "Systems engineering...... Integration...... Effectively combine the knowledge in the existing disciplines and integrate the comprehensive development of aircraft ......"

Ba Yuzao's words surprised Song Zhewu very much, not because of Ba Yuzao's obsessive demeanor, but because of Ba Yuzao's self-talk. Ba Yuzao's self-talk is very close to the definition of systems engineering that emerged more than 20 years later. Although there are more than a dozen definitions of systems engineering, and each of them is somewhat different, it is only a difference in focus and perspective, and the purpose is still the same. Song Zhewu remembers that one of the definitions is that "systems engineering is an engineering technology that effectively combines the knowledge of existing disciplines to solve the problem of integration". Just based on his own very unsystematic words, he can roughly understand and summarize that this Ba Yuzao is really not simple.

Seeing that the excited Ba Yuzao was a little distracted, Wang Zhu secretly pulled the sleeve of Laba Yuzao under the table.

Ba Yuzao came back to his senses, and did not feel the slightest embarrassment, but continued to follow his train of thought and said: "Commander, when it comes to integration, I have come up with an idea, can we and people from other disciplines jointly form an "Aviation Development Committee", and the problems that need the help of other disciplines in aircraft research will be coordinated and arranged by the committee. ”

"Good! Very good! Song Zhewu couldn't help but admire Ba Yuzao's cleverness. He just pointed out a direction, and he immediately thought of a concrete plan for implementation. The method of setting up this committee is excellent, and all the designs and materials that appear in the development of new aircraft that he cannot solve by himself, or that have no precedent in the world, will be studied and solved by this committee in a planned manner by other disciplines. This will be the world's first scientific research method that puts aircraft development into comprehensive research in various disciplines and jointly tackles key problems around the needs of new aircraft. With this relatively scientific and reasonable method, Song Zhewu believes that although his scientific research strength is still very weak, because of the effective system, he will definitely create a miracle within ten years.

Song Zhewu pondered and said: "In my opinion, the establishment of the Fourth Route Army Aerospace Development Committee will be headed by Brother Yunhua, and the members are Wang Zhu, Wang Xiaofeng, Zeng Yijing, Gao Zhihang, Guo Wenyuan, Li Minghua, Cui Hao, and the heads of the Optics Research Institute, as well as the chief technical leaders of the newly established New Materials Research Institute and Hydraulic Research Institute in Wenyuan. The Committee should meet regularly to study and discuss aviation issues and to arrange for the deployment of various problems that need to be solved by various disciplines. All the issues studied and discussed by the committee are the top secret of our Fourth Route Army. It is necessary to do a good job in the confidentiality system. ”

Song Zhewu's decision made everyone present very happy, and Song Zhewu's decision to make this decision so happily shows that Song Zhewu attaches great importance to the development of aviation, which makes these aviation experts very excited.

"But in this way, will it affect the scientific research of other disciplines because of the affairs of our Aviation Institute?" Ba Yuzao asked embarrassedly.

"No, absolutely not. Not only will it not affect their research, but on the contrary, it will greatly promote their scientific research, and it is precisely because of your needs that they will be prompted to carry out scientific research purposefully, and the efficiency of purposeful research will be higher. It will not only be able to keep up with the weak scientific research force of our Fourth Route Army, but will also accelerate the development of various disciplines. At the same time as the development of aviation technology, it will inevitably give birth to many new technologies, and many of these technologies will even be revolutionary, they are not only military, but also civilian, not only our military industry needs, our Xinghua company will also need, because the continuous emergence of new technologies can even change the status quo of our country's weak scientific and technological development to a certain extent. ”

Song Zhewu knew the great significance of this committee, but he remembered that in his previous life, the United States relied on automobiles, airplanes, atomic bombs, and aerospace, as well as a series of major scientific research projects with clear objectives, such as the "Star Wars Program" during the Reagan political axe period and the "Anti-Missile Program" during the Clinton and Bush periods, to give birth to many new technologies and concepts that were ahead of the times, and led the United States to always run at the forefront of the world in science and technology.

If he can use the aircraft as a system engineering platform to drive his limited scientific and technological strength during this period, he may be able to make a big leap forward in the scientific and technological strength of the Fourth Route Army.

"Good! Just do as the commander says. Ba Yuzao replied solemnly. It's just that I have one more request. ”

"Brother Yunhua wants to talk about the problem of funds, right? I know that it takes a lot of money to build an airplane, but please rest assured, as long as you need it, I will never let Brother Yunhua worry about money. Song Zhewu said with a smile.

"I believe the Commander on this, but that's not what I'm talking about." Ba Yuzao shook his head and said.

Looking at Song Zhewu in the group, Ba Yuzao continued: "That's right, I don't think there is a large-scale invasion of foreign enemies in our country today, and we don't need to have a powerful fleet to fight a civil war, just our DH-10 is enough." What I mean is that we should not rush to produce a large number of aircraft, and at this stage we should mainly do a solid job in the basic work of developing new aircraft, absorb the experience of foreign advanced aircraft design, and make good technical reserves. This requires the appropriate purchase of a small number of foreign advanced aircraft, which will be used for decomposition and study, and on the basis of learning the advantages of foreign advanced aircraft design, we will design our own aircraft. ”

"The planes we have designed should not be in a hurry to be mass-produced now, each model must have a high standard, and the six words of the commander must be used as the guiding direction, and none of the one or several items will be launched if they meet the standard, and for the time being, each type of aircraft will only produce the number of squadrons. Because now the development of aircraft technology in the world is very fast, and now advanced aircraft will become obsolete in a few years, and if each model is mass-produced, we will have a lot of second- and third-rate aircraft in a few years, which will waste a lot of resources. I mean that we will not be able to mass-produce until we come up with very mature aircraft, very technologically advanced, very good aircraft that have been leading for a certain period of time. ”

Song Zhewu agreed with Ba Yuzao's words, although the "9.18" incident is likely to occur in 31 years, but in less than two years, it is somewhat unrealistic to let Ba Yuzao and them come up with a new plane, and it would be very good to be able to come up with relatively advanced aircraft at the beginning of the all-out war of resistance. And in 37 there are still seven or eight years to go, and if a large number of aircraft are produced at this time, by that time, these aircraft must all be obsolete.

Song Zhewu actually had this intention for a long time, but he was afraid of dispelling the positive surnames of these aviation experts, so he didn't dare to say it, Ba Yuzao took the initiative to put it forward, which made Song Zhewu very happy, and immediately agreed.
