My 1979

Qi Gongxun took the opportunity to see off Professor Wu and locked the door behind him.

This inadvertent action did not escape Li He's eyes. Since they came in the name of magazine editors, it meant that they did not want anyone to know.

He was also happy to pretend to be ignorant. Entering this vortex, it is not easy to escape. Serving the country does not necessarily mean working hard in Lop Nur.

The bearded Guo Dong politely poured a glass of water for Li and said with a smile, "Mr. Li, we didn't expect you to be so young. Our "Weaponry Knowledge" is a journal sponsored by the Ordnance Industry Association and supervised by the Science and Technology Association. . We recently wanted to do a study on the development trend of rocket launchers, and we hope to get some advice from you."

Li He had a deeper understanding of Guo Dong's ability to tell lies with his eyes closed, but he still complained on the surface and said with a smile, "You're welcome, we can learn from each other and make progress."

Qi Gongxun asked, "You seem to know our army's 70-type 130mm self-propelled rocket launcher very well, because we only transferred to mass production of the 130 rocket launcher in 1979 and officially equipped it with our army's armored forces. And our weapons magazine is in the middle of the new weapons Due to the principle of confidentiality, there is not much introduction, how do you know about it?"

Qi Gongxun's question was meaningful. Li He immediately turned his brain a hundred times before secretly cursing himself for being such a stupid fool. He could only force himself to calm down and asked, "Use 63 for 70 moves." It’s not a secret that the armored vehicle is used as a weapons platform, right?”

Qi Gongxun and Guo Dong looked at each other and said with a smile, "We all know this."

"The rocket launcher consists of a director, a rotary disc, a height machine, a steering gear, a marching fixator, an aiming device, a leveling device and a firing system. It is not complicated in terms of structure. And since the Type 63 is used as the platform, in order to adapt to the installation If the vehicle is needed, part of the structure of the gun needs to be modified. During the counterattack against Vietnam, the Type 79 was included in the pictures accompanying the People's Daily report on the battlefield. The Type 79 in the picture changed the installation position of the sight and rearranged it. The height machine and steering wheel are removed; a leveling mount is installed on the chassis body, and the leveling base on the rotary body is cancelled. As long as you know a little bit about rocket launchers, you can see it, right?"

Li He didn't lie. He had actually seen the photo of the Type 79 in the newspaper.

The two men nodded in approval again.

Li He continued, "And the anti-aircraft machine gun on the top deck has been replaced by a rocket launcher. If I can't tell the difference between an elevated machine gun and a rocket launcher, wouldn't I be a fool?"

After he finished speaking, the two people laughed.

I knew in my heart that this was a fool's errand.

Guo Dong asked again, "Do you think the development trend of rocket launchers is to become autonomous?"

"It is a trend, but not an obvious development trend, because the Soviet first-generation rocket launcher "Katyusha" that showed its prowess in World War II was installed on a five-and-a-half-ton truck. Almost all rocket launchers used by the warring countries in World War II were There are self-propelled rocket launchers. I think the future trend is not only to be self-propelled, but also to be able to achieve long-range strikes, at least more than 70 kilometers. The second is high guidance accuracy. The third is large firepower and multi-barreled salvos. If If the above points are not achieved, the position of the rocket launcher will be very awkward."

"Why?" Qi Gongxun interrupted this time.

"We have missiles for precision strikes and artillery for fire attacks. Why do we need rocket launchers?" Li He said and took a sip of tea. When he walked in, his throat was uncomfortable. He thought he might have a cold.

The three of them seemed more and more happy as they talked, but Li He deliberately kept an eye out and made some obvious mistakes in some places, and then asked the two of them to correct them with sincerity.

"In your paper, you mentioned the application of structural dynamics and structural optimization theory to conduct research on rocket launch dynamics and matching analysis of the dynamic characteristics of each component to achieve the purpose of reducing initial disturbance. This involves simulating the finite limitations of the original structure. Element model. Can you popularize this finite element analysis for us?" The questions Guo Dong asked seemed to be getting deeper and deeper, beyond the scope of an editor's knowledge.

Li He knew that he could not answer any more, otherwise he would be remembered and he would not have a good life. He pretended to be helpless and scratched his head and said, "This is embarrassing. After all, I have only studied high school mathematics for four years and my ability is limited. But still Don’t be embarrassed, there are a lot of people in China who know these things. Our principal is an expert in fluid mechanics. To establish a three-dimensional model, finite element analysis is commonly used. Moreover, when our domestic road engineering construction encounters soft foundations, finite element analysis method It is also indispensable. And our bridge construction, such as the Yangtze River Bridge, also uses the finite element method to analyze the roll stability of the combined system."

"Really?" Qi Gongxun asked uncertainly.

"Of course it's true. The things I have are only half-understandings I got from journals and newspapers, just picking up people's wisdom." Li He didn't know how much he sighed when he was reborn. Sometimes, there is no shortage of experts in certain fields in the country. What is lacking is the integration of resources for certain research results and projects. I don’t know how many people are doing repetitive research, and how much resources are wasted.

In the field of science, the United States implements a socialist model. It concentrates its efforts on big things. If there is a disagreement, it will launch a "Manhattan Project" or a "Moon Landing Project."

Every time the two asked some questions, Li He would rack his brains to recommend some experts or published journals and magazines.

In the end, when the two of them racked their brains and couldn't think of any questions, the conversation ended.

Guo Dong excitedly gave Li He a bear hug, "Teacher Li, thank you very much for your help. To express my gratitude, I would like to buy you a drink."

"Yes, Teacher Li, you are familiar with the place. You choose a place and let's have a few drinks." Qi Gongxun also pulled Li He and asked to go to the restaurant together.

What can Li He do? They are curious Teletubbies, but he is not an easy-to-remember star. He doesn't want to continue to deal with it at all. He has to escape for his life. He said righteously, "Thank you two editors. I also want to accompany you two." As a landlord, I haven’t prepared the lesson plan for tomorrow, and it’s the end of the term soon, so things are quite complicated. I hope you can understand that as a teacher, I first need to be responsible for my students.”

The two people immediately expressed their understanding and gave Li He a professional and responsible label.

Li He just walked out of the office door and took a breath of hot air.

Maybe I really have a cold, dizziness, sore throat, and sore eyes. After clearing my nose, my eye circles turned red. Said to himself: "I don't know if I have done something wrong in my life."

He went back and drank a large glass of boiled water, and did not buy medicine or eat dinner. He felt cold all over and covered himself with two thick quilts. His head was as heavy as a millstone pressing on Li He.

Although Li He was not asleep, he could not wake up. He was so heavy that he could not lift his head.
