As soon as he saw Xu Dongcun bring a young man in, an old professor who was standing in front of the podium projector fiddling with the equipment suddenly changed color, looked at Sun Cheng unhappily and said, "Old Xu, today's discussion is a confidential topic, why did you bring someone over?" ”

This professor's name is Liu Qiangjun, the main professor of aeronautical systems engineering. Pen & Fun & Pavilion www.biquge.info

Sun Cheng couldn't help but be taken aback when he heard this, studying at Imperial University, the top science and technology college in China, and most of the students knew very well the meaning of 'secret topics'.

At worst, it is to provide some theoretical basis for the [Aviation Power Research Institute], and at worst, it may be to provide technical support for military equipment that has been filed in the 'Ministry of War' or the 'Ministry of Industry'.

Hearing that Liu Qiangjun was about to drive people out as soon as he opened his mouth, where was Xu Dongcun willing.

I saw that his beard shook and pointed at the other party and said: "Lao Liu, you are not authentic, a few years ago, everyone exchanged the aerodynamic layout of the fourth-generation aircraft, which was a real 'secret topic'." As a result, you stubbornly bent on your cheeks and brought your kid in to listen, why didn't you see that you were principled at that time. ”

The old professor was suddenly dumbfounded, but his face turned red.

As soon as he saw someone blushing, the few people sitting below also started a round.

Wang Nian, the professor of aeronautical materials science, said to Liu Qiangjun with a smile: "Okay, old Liu." It's not a 'secret topic' today, I look very familiar with this young man, and he must be a student we have taken, let him sit there and listen for a while! ”

"That's it!"

Zhang Danian, the chief professor of aircraft structural mechanics, pointed to Xu Dongcun, "Lao Xu was robbed of a few good seedlings by us before, and it is rare that he has found a favorite student this time, so how can he give some face!" ”

"Hmph, Lao Zhang, don't think it's enough to say a few nice words to me. The little girl I fancied the year before last was cut off by you, if it weren't for the sake of that half bottle of ten-year-old wine, I would definitely smash your window! ”

"I've smashed you once, and you want to smash it again!"

Sun Cheng listened to it with pleasure, and felt that he, a cheap teacher, had really smashed someone's window.

Someone gave it to the bottom of the stairs, plus the two of them have known each other for decades, even if they don't see each other, there is no deep hatred, so although Liu Qiangjun still has a face, he didn't continue to talk about it after snorting, and stood on the podium by himself and fiddled there.

"Come on, boy, sit here!"

Yang Jin, who majored in flight automatic control theory, was a good man, and many students would take credits from him when they didn't have enough credits, and at this time, he also took the initiative to invite Sun Cheng to sit near him.

"Lao Xu, your little apprentice is a student we have taken, right?"

Deng Changlin, the old professor who was in charge of the principle of aero engines, pushed his glasses and looked at Sun Cheng seriously, and the more he looked at it, the more familiar he felt.

Without waiting for Xu Dongcun to reply, he suddenly tapped the table and said, "Oh, I remember." Your name is Sun Cheng, right? ”

Sun Cheng nodded: "Yes, Professor Deng, I'm Sun Cheng!" ”

He is not surprised that Deng Changlin can still remember himself, because a few years ago in Deng Changlin's lecture hall, Sun Cheng had a heated discussion with him on the issues of the Soviet Union, the United States, the British and the Chinese.

Deng Changlin looked at him and suddenly laughed, "I remember, you kid is quite stubborn." How about it, do you still think that the Soviet-style engine is more suitable than the British and American ones? ”

A few years ago, in a class, I talked about the relationship between domestic engines and the lack of talents in recent ten years, and at the same time, some material technologies have been delayed in breaking through, resulting in the trend of Guofa being thrown away by the United States, the Soviet Union and Britain.

In the era of second-generation aircraft, there is only a half-generation gap between Daming and the Soviet Union, the United States and the United Kingdom, and the middle push is almost neck-and-neck.

But in the era of the third-generation aircraft, it has been thrown away by nearly a generation.

In recent years, even the middle push that Daming is proud of has been thrown out of the first team.

The fourth-generation aircraft suffered from heart disease before it took off, and the domestic large-scale thrust technology was slow to mature.

Looking around the Ming Dynasty, there is the Soviet Union in the northwest, the Wailiao puppet Houjin State in the northeast, Goryeo and Shengyang in the east, Tianzhu in the southwest, and several ASEAN countries in the south in recent years, which are also jumping everywhere, with an extremely severe sea and air defense situation.

In the early years, the Ministry of War had to grit its teeth and squeeze out some of the military spending, and purchased the early F100 engine from the United States, which was castrated and had to be added with various conditions and restrictions.

Although, after more than ten years, Daming has almost been able to produce F100 by itself, but in terms of life and performance, not to mention being on a par with the legendary F110X, even the F110-GE-129, which is disliked by the US military itself, is also a line worse.

In this way, during the fourth Ryukyu crisis in 2008, the four golden eagles of the Ming Dynasty were still tragically staged by a strange fighter of unknown model in Shengyang Kingdom, and it is not an exaggeration to say that it was a loss of face.

Therefore, in Deng Changlin's previous class, he said with emotion that now that Daming is in a deadlock in national development technology, it is very necessary to introduce an advanced engine from Europe and the United States.

Sun Cheng was just the opposite of his opinion, on the contrary, he was more optimistic about the Soviet-style engine with rough skills and production technology that was relatively more suitable for the Ming Dynasty, so he proposed that the Ming Dynasty could take advantage of the economic recession of the Soviet Union in recent years to try to see if it could get some advanced aviation engine or even technology from the Soviet Union.

As soon as he heard Deng Changlin mention this, Sun Cheng couldn't help but feel a little flustered.

Due to the existence of Xu Dongcun, he just smiled slightly and neither refuted nor admitted, which can be regarded as a smarter way to avoid it.

Deng Changlin obviously understood what he meant, and scolded with a smile: "Little slippery head!" ”

turned to look at Xu Donglin again, pointed at him and said, "Your temper is a little stinky, but your vision is good, and you have met a good seedling!" ”

Xu Donglin raised his head proudly, pulled Sun Cheng to sit down next to him, and handed him the document bag under his armpit.

"Teacher, what is this?" Sun Cheng hadn't reacted yet.

Seeing that others had noticed their small movements, Xu Donglin didn't care, and didn't mean to lower his voice at all, "You take a look first, just preview in advance!" ”

Sun Cheng saw that the others had no intention of objecting, so he immediately answered and took it, only after checking it in his hand and realizing that there were a lot of things inside, he quickly opened it, took out a bundle of standard copy documents that were afraid that there were twenty pages small, and when he looked at it, a strange color immediately flashed in his eyes.

【On the positioning and analysis of UAVs in the military and civilian fields】

After flipping through the homepage a few more times, Sun Cheng quickly determined that he had read most of the things in this document in the past.

In order to verify his guess, he recalled while reading, and the documents in his hand flipped faster and faster, which immediately attracted the attention of several old professors present.

Not long after, when he completely closed the document and put it in front of him, Xu Dongcun quickly lowered his voice and asked a little unhappily, "Why do you see it so quickly?" Although you don't want to write down all the things in it, it is good for you to remember more things in the future. ”

"Teacher!"

As soon as Sun Cheng looked up, he noticed that several eyes were all focused on him, and he deliberately lowered his voice at the moment, and replied flatly: "There is nothing new in the document, more than seventy percent of them are from several foreign articles and magazine reports in the Imperial Digital Library, I happened to read it in the past!" ”

"What?"

Liu Qiangjun's face on the podium not far away changed suddenly, and he scolded loudly: "Just a few minutes after you just flipped through the scenes, you only watched a few more things, and you dare to talk nonsense!" ”

Seeing that he suddenly became angry for no reason, although Sun Cheng was surprised by his attitude, he still calmly defended himself: "Professor, I didn't talk nonsense. Except for the third and last paragraphs, the prologue on the first page of the document is mostly from the prologue of Document No. 1036 in the Foreign Resources Area of the Imperial Digital Library, originally written by Jacob Melhatz, an Israeli; Although the contents of chapters 1 and 2 have been modified to a certain extent, it can still be seen that they are also direct translations of Document 1036; Chapter 3 is partly based on the introduction of the US military's 'MQ-1 Predator' in Jane's Global Aircraft in July 2004, which is included in the library, and the fourth chapter is almost entirely translated from Document No. 1044 of the Foreign Resources Area of the Imperial University Digital Library - 'Analysis of the Global Drone Market', written by Australian military councillor Alexia Burbit. The epilogue is from the Swedish Saab Defense Review of the European Neuron UAV related article ......"

As soon as he finished speaking, he saw that Liu Qiangjun's face on the podium was blue and red for a while, and it was very ugly.

was wondering, but Xu Dongcun pulled his sleeves and asked, "Are you not mistaken?" ”

Sun Cheng shook his head, "I happened to have seen it when I was in the library before, if you don't believe me to write a note, write down the numbers of several documents, and go back to the digital library of the Imperial University to check it out!" ”

After speaking, he directly took out a pen and a palm-sized notebook from his pocket, opened it, quickly wrote down several sets of sources on it, tore it off, and solemnly placed it in front of Xu Dongcun.

Glancing at the document in front of him inadvertently, Sun Cheng noticed that the name of the writer of the note was 'Liu Yilin', and suddenly glanced at Liu Qiangjun on the podium as if he understood something.

Turning his head, the moment he looked at Xu Dongcun, the old man raised his mouth, nodded lightly, and almost told him that this 'Liu Yilin' dared Liu Qiangjun to have something to do with it.
