Military Industry of Great Powers: Build the Strongest Flanker

"Dear teachers, we plan to use CAD three-dimensional modeling to build a missile model in the computer. This model is quite different from ordinary CAD images. Each component of the missile defines the properties of each material, including tensile strength and compression resistance. , elastic modulus, quality..."

"This gives us the first function to analyze, which is the calculation of the center of gravity of the missile body!"

"Each component can simulate aerodynamic, gravity, impact, vibration, and noise loads under different conditions!"

"This brings us to the second function of analysis, which is overall stability, overall vibration, and overall flight status analysis."

"When the engine load is added, a dynamic balance analysis can be performed, in which variable variables can be added to analyze the missile's state changes."

Shi Wenxiu spoke very slowly. Everything he said was based on logical arguments. There was no sound in the audience, and everyone was deep in thought.

"The above is an overall analysis, but for each component on the surface, using the principles of aerodynamics, I use the currently mature finite element analysis and use the powerful computing power of the computer to calculate the load borne by the components and the load transmitted through the connectors. The data applied to the load on the body are also used in the overall analysis.”

"We introduced advanced foreign hypersonic aeroelastic modeling and a hypersonic unsteady constant calculation method based on CFD computational fluid dynamics to establish a tool model to analyze stress concentration locations such as the missile head, canards, tail fins, and fuselage. Perform analysis, especially in the face of the head-effects of flutter analysis.”

"At the same time, we also simulated composite tests on thermostatic force, thermal vibration, thermal noise, and rudder structure..."

Can you understand?

I can understand!

The mathematical tools and testing methods used are still in use.

It can be done with a computer. No one has tried it. Oh, no, no one has seen it.

Ji Hongbo felt like he was doing nothing, sitting here like a country bumpkin. He looked at Zhao Guoqing with a puzzled expression and asked: "Guo Qing, can you do it?"

Zhao Guoqing nodded. There is no technical problem. The problem is that the computing power of the computer may not be enough. Even the IBM sys370 medium-sized computer in the computer room is not enough.

But Teacher Xiao Zhao has a way.

Mathematically, to calculate the area of ​​a circle, take the center of the circle as the corner point and draw n equal isosceles triangles. The more triangles are divided, the closer the calculated value is to the area of ​​the circle. Five million triangles will definitely have higher accuracy. But the results of five hundred triangle calculations can also be used.

If the computing power is not enough, just sacrifice some accuracy.

Chief General Chen Qiurong asked: "General Master Zhao, are there similar technologies abroad?"

Zhao Guoqing nodded and said: "Foreign countries have used computers to carry out various simulation designs in the 1950s, but now there is no comprehensive software. Aircraft design has already begun on AutoCAD."

Ji Hongbo said: "Does the missile body modified by R530 need to be optimized with this software?"

Zhao Guoqing smiled bitterly, Ji Hongbo really regarded him as a god.

"It will take half a year at the earliest, maybe more than that, before the first version of the software can be released."

Chen Qiurong said: "This is an eye-opener. Director Zhao, after the software is finished, can you send a copy to our 317 Factory?"

Here we go again, everyone wants to have sex for nothing, how can this be done?

Teacher Xiao Zhao believes that knowledge is valuable. For this reason, he and Director Liu Qing had an argument. To Mr. Chen, he said in a very gentle tone: "Mr. Chen, we plan to sell a set of this software for one million yuan." Of course, if 317 Factory can provide us with technical support, we can provide it at a preferential price. If it is key technical support, we can provide the software for free, and even share the revenue from selling the software with you according to the technical ratio!"

"..."

Everyone was dumbfounded, look at me, look at you!

Everyone is still very uncomfortable with Teacher Xiao Zhao's "philistine".

Especially Chen Qiurong and Shi Peigang, they felt a sense of offense.

Gao Changming hurriedly accompanied him and said with a smile: "Chief Engineer Chen, Chief Engineer Shi, it's like this. You guys also saw it when we came here. Now there are seven research centers, five workshops, and three research buildings under construction in the 101 Institute." , three material workshops, a photolithography machine factory, and an electronics factory. These properties do not require a penny of state funding, and it is not easy for Director Zhao!"

"..."

Gao Changming wanted to complain, but it sounded a bit like showing off.

Ji Hongbo listened happily. Hui Province was all grateful to him. If he hadn't been far-sighted, how could he have attracted this golden phoenix?

Du Chumingke told him that Hui Province's economic growth this year is very gratifying, and its foreign exchange has basically achieved independence. It basically does not require state support to meet the needs of enterprises in the province to upgrade production materials.

But Chen Qiurong and Shi Peigang really can't afford it. With so many houses and so many equipment, they can't afford tens of millions!

Gao Changming said: "Three hundred million have been spent before and after!"

"..."

As for how proud he is, Gao Changming's vision has also become much higher. In the past, a few hundred thousand for 14 institutions was a big deal, but for one or two thousand, he would hold a 14 team meeting.

Now, 14 institutions have more than 10 million on their books.

This is the result of Comrade Zhao Guoqing's priority to meet the needs of 101 before reducing dividends.

I heard Li Guangquan, an accountant from 14 firms working in 101 firm, say that next year’s 30% dividend will definitely exceed 100 million.

Gao Changming thought to himself: "Chengfei doesn't even have that much money on his books!"

The meeting was very successful, and the report was formed on the same day, because this project was initiated by Kong Zhi. After the experts signed it, it was sent directly to the military vehicle parked at the door and sent to the capital as soon as possible.

After sending the expert to the guest house, Gao Changming returned to No. 101 to find Zhao Guoqing.

Gao Changming asked: "National Day, I thought about it, can the software reported by 101 just now also be used in aircraft design?"

Zhao Guoqing nodded and said: "Director Gao, I was just about to report to you. I want to send a letter to Chengdu Aircraft Research Institute in the name of the 14th Institute, requesting them to send someone to provide technical support to us. After all, designing missiles is not as important as designing aircraft. A lot of different ones.”

Gao Changming said: "I think it will work! If nothing else, it will definitely be No. 53. I haven't seen Chief Lu Zhen for a long time!"

Institute 53 is a flagship unit of Chengdu Aircraft Corporation of China and has participated in all major projects of Chengdu Aircraft Corporation of China.

"National Day, there is one more thing I want to discuss with you?"

Zhao Guoqing smiled and said: "Director Gao, you just need to give direct instructions!"

Director Gao's expression didn't look good.

"On National Day, 14 schools are having a good time. Can we support Yi Yi Cheng Fei? Their life is not easy right now!"

"..."

Teacher Xiao Zhao's face suddenly turned ugly. If he wanted to give money, how could that be done?

"Director Gao, do you think we can try another way?"

The author's head is hot, his eyes are dazzled, his breathing is heavy, and his body temperature is rising. There are only three chapters today, and I am really sleepy.
