Yi Xiaoyi and technicians spray paint on J-15S No. 311.
Li Hai came over, circled around the fighter plane, pointed at the small spray paint machine, and said, "General Manager Yi, aren't you applying car paint? Why does it look like a car spray painting machine?"
"This is a new product, a small field paint protection machine that can be pulled by a truck. It can be plugged in and filled with mixed paint, and then sprayed directly. However, the requirements for the operator are very high," Yi Xiaoyi said.
He pointed to the machine that was undergoing fully automated spraying and said, "This is a field-style fully automatic spraying machine. It has strict requirements on the installation environment. In order to ensure the joint military exercise, the Peace Base specially installed one. , now it’s more convenient for us.”
After sizing up the maintenance hangar, Li Hai nodded and said, "This maintenance hangar is relatively modern. That's right, why did the good guy change his paint? I think the shit yellow paint looks pretty good too."
"That was the original factory paint, which does not meet actual combat requirements. Now it is painted with a low-visibility light gray paint specially designed for the navy. It is anti-corrosion and rust-proof. It also has absorbing materials and has a certain stealth effect." Yi Xiaoyi smiled. He said, "Don't worry, this painting is very expensive."
Li Hai asked, "How expensive is it?"
"It's more expensive than the average price of houses in Beijing's third ring road." Yi Xiaoyi said.
Li Hai was stunned for a moment, "Your comparison is really first-rate."
"But it's not as good as No. 1 Shenzhen Bay. The housing prices there are much more expensive than our painting." Yi Xiaoyi sighed.
Li Hai laughed loudly. Yi Xiaoyi did not have the serious side of a scientific researcher. Instead, he was more humorous and had a particularly high emotional intelligence.
"It's really expensive, oh, I mean this kind of painting." Li Hai said.
Unfortunately, this dark humor is true. House prices are too high!
Yi Xiaoyi said, "You're here just in time. Let me tell you about tomorrow's test flight."
He and Li Hai left the maintenance hangar and came to the small building where scientific researchers were stationed. This building was right next to the maintenance hangar.
Yi Xiaoyi took out a stack of paper materials and said, "Tomorrow is an adaptive flight to comprehensively test the performance of each system of the fighter jet in the current terrain environment. There is a complete test flight process in it. You can take a look first. Our family is working overtime tonight. , integrate all the sensors and reduce your work intensity."
"Thank you, let me take a look first." Li Hai sat down.
"Where's the little party?" Yi Xiaoyi asked.
Lehi said, "He went to see the ammunition."
The pilots in the rear cabin are mainly responsible for operating weapons, so Dang Weimin ran to the ammunition depot to check the ammunition for this high-altitude test flight, and to familiarize himself with the parameters and performance of the ammunition, as well as some matters that need attention.
"You have to do some work in advance. Most of the ammunition for the No. 15B project is new. Many of them were specially developed for our project and are different from what your army is using now."
Yi Xiaoyi smiled and said, "It's more advanced, easier to use, and more powerful."
Li Hai looked up at Yi Xiaoyi and asked, "Can you tell me something?"
"I'm not very sure either. You can just look at them. Most of them are unformulated ammunition." Yi Xiaoyi said.
Li Hai said, "I really have to study seriously. When it comes to unformulated ammunition, safety comes first."
"Don't say that, it's unlucky." Yi Xiaoyi said.
Li Hai smiled and said, "General Manager Yi, you still engage in feudal superstition."
"Xiao Li, I'm not kidding, I'd rather believe it, you know?" Yi Xiaoyi said seriously.
He recalled it for a moment and said, "Let me tell you a real example."
Li Hai put down the materials in his hand and waited for the next chapter.
"Many years ago, there was a static instability test flight. At that time, a J-7 modified test aircraft was used, which was specially used to fly static instability. Before takeoff, the pilot joked that he was not afraid of not being able to correct it. The result was really It didn't change, but fortunately the pilot ejected smoothly. I had just graduated and joined the factory at the time, so of course I didn't believe it. It must have been a coincidence. Then it happened again. That time we were doing a maximum speed test and wanted to fly outside the envelope. This The project was relatively simple, and the risk was not that high. Before getting on the plane, the pilot said he was afraid of hitting a bird, but he was afraid of hitting a bird. As a result, he hit a bird just after takeoff, and the altitude and speed were not even increased. At that time, there was only one prototype left, and the pilot had no idea. I tried my best to save the fighter plane by parachuting, but unfortunately I couldn’t save it, and both the man and the plane were gone.”
"So, Xiao Li, don't say such things."
Li Hai was stunned for a while.
"Okay, I understand, Mr. Yi."
Although he didn't believe it, he knew that if he didn't listen to the old man's words, he would suffer a lot, so he nodded and agreed.
Yi Xiaoyi emphasized again, "We must not say it again."
"Okay, I've written it down."
After reading the document, Li Hai made a copy of the test flight content and took it with him, and returned to the maintenance hangar with Yi Xiaoyi to check the status of the fighter jet.
The fully automatic spraying machine is quite powerful. Several robotic arms spray various parts of the aircraft in a targeted manner. How much should be sprayed where and how large the range is. It is controlled by the central processor. The data is set in advance. During the spraying process There are also a variety of sensors in the machine that monitor at a frequency of dozens of times per second, constantly fine-tuning the accuracy of spraying to ensure that the error is within the required value.
There is only one thing one needs to do - press the start button.
In less than an hour, the No. 311 J-15S had changed into new clothes. It was a standard naval fighter low-visibility light gray paint. However, the difference was that except for the Shen Hoi dog on the outside of the vertical tail and the sides of the cockpit. There is no identification other than the "311" number.
Yi Xiaoyi said, "The next step is to integrate the sensors. We integrate all the sensors into a control system, turn them on and use them, and uniformly monitor all the data of the aircraft. It usually only takes a few seconds to feed back to you."
"This is good, this is good." Li Hai nodded repeatedly.
After so many actual battles, he has become more and more aware of the huge usefulness of the sensing system. What is used on fighter aircraft is called the battlefield situational awareness system. Fourth-generation aircraft have four aspects that third-generation aircraft do not have. One of them is super battlefield situational awareness capabilities.
The battlefield situational awareness capability of fighter aircraft is not only to convey more battlefield situations to pilots, but also to simultaneously transmit them to air command aircraft or ground command centers. From the perspective of commanding operations, each fighter aircraft is a multi-purpose aircraft with multiple capabilities. With the tentacles of information capture capabilities, commanders can timely understand the development of the battlefield situation and changes in the situation between the enemy and ourselves, so as to make command decisions quickly.
The method proposed by Yi Xiaoyi has the same reason.
The ground side is sometimes more aware of changes in the fighter aircraft's situation than the pilots, so the pilots can be notified in a timely manner.
One of the keys to why the No. 037 J-7EGGHS is so awesome is that it has a very powerful battlefield situational awareness system, which many third-generation fighter aircraft cannot match.
Li Hai said with confidence, "I am more confident about tomorrow's test flight."
