Chapter 263 (1/2)
”But our No. 3 aircraft carrier has been installed in the later stage. We don't have time to study slowly, so we have today's meeting!”
Su Anguo said to the staff on the other side, ”Xiao Chen, send the information to everyone!”
”...” a young man took a piece of information and distributed it.
After waiting for more than ten minutes, after the materials were distributed to everyone, Su Anguo put his hands on his desk and said, ”chief engineer Li, your institute has been moving forward in terms of accuracy in China.”
”We have 15 accessories, A15, a521, D52, e586 and S05, which can't be processed because of the accuracy of the equipment!”
”Now the required parameter is that the refraction is 950yp, the reception is - 1050bd, and the accuracy should be up to 0.02mm. I wonder if you can help solve the problem!”
With expectant eyes, Su Anguo looked at a middle-aged man in his fifties in a gray Zhongshan suit in the second row.
Chief engineer Li saw Su Anguo ask himself, stood up, looked at the information in his hand, frowned and said helplessly: ”Mr. Su, I probably looked at it just now. The specifications of your accessories are large and super large. I'm afraid it's very difficult to achieve the accuracy of 0.02mm!”
”If it's a small accessory, don't say 0.02, even 0.01, I'm sure to help you process it!” Chief engineer Li knows that jg0002 exists naturally.
”This accuracy is already our limit. No matter how large it is, it will not meet our requirements.” Su'an was helpless.
”Our institute has always been a short board in large-scale processing. I can only say here to try, but I dare not assure you!”
”Well, after the meeting is over, I will go back to the Institute to communicate with the technicians and try my best to process this part!” Chief engineer Li could only say vaguely in the end.
Great pressure!
”The first problem is chief engineer Li!” Su Anguo continued: ”now the second problem is the accuracy and sensing system. This is the material problem!”
”Mr. Su, can we change IDR materials? These are very mature materials. You should also know that materials and accuracy are our weaknesses!”
......
Because this is the truth, everyone didn't speak and waited quietly for the following.
”I've seen what you just said. The S-wave radar uses a very high frequency 550ha and a millimeter wavelength of 0.3. It has very strict requirements in terms of materials!”
”The material you require not only has the characteristics of large band gap, high breakdown electric field and high electron saturation drift speed, but also has very high requirements for the response of high-frequency signals!”
”When the module power utilization is limited, most of the energy is converted into heat loss. When more than 2000 tr units in the whole array are working, the heat generated is quite huge, which is another material difficulty!”
”Therefore, the heat dissipation performance must be very good. It can work normally when the temperature difference is quite large, which is very harsh for space tension and weight distribution conditions!”
”With an output power of more than 180W in the X-band, the output power of MMIC (monolithic microwave integrated circuit) has been greater than 35W. Each parameter is a great difficulty for now!”
“......”
Look back at Zhou Meng
Time goes by slowly.
It's almost time for the ball.
”Come on, let's go out!” Li Hong said, ”Zhou Meng, you play with your classmates first. I'll call those entrepreneurs in the VIP room.”
”OK!”
On the sofa in the VIP room, six people are playing business with each other, four of them are middle-aged, two young people, a man and a woman.
These two young people are Guo Xiuqing and Lei Feng, as Cai Yeer and Zhou Meng said.
Gu Feng is about 1.85 meters tall. He wears a dark suit and his shoes are blinded. He looks like I'm a big man.
