"President Qin, I've been looking up to you for a long time." Li Xiangyu came up and shook hands with Qin Guan. This man is a miraculous existence. He suddenly rose like a God in the tide of reform in the Han country.

Now, the promoter behind this super seven project is also Qin Guan. Now that I see him, Boeing should also attach great importance to him.

"The engine of our plane is poor now," Qin Guan said. "Our technicians are trying to repair the engine. If it is repaired, we can continue to test fly."

After hearing Qin Guan's words, Ralph was quite puzzled. What's the difference? Are you bragging?

"Mr. Qin, what about the engine?" Ralph asked, "where's your radar, fire control and navigation equipment?"

"We have a plan," Qin Guan said. "By the end of the year, Chaoqi will be in full state. Now, we have completed the improvement. In order to improve its performance, we have introduced telex operation in the vertical direction."

Telex operation? Ralph was stunned when he heard Qin Guan's words.

Laymen watch the excitement and experts watch the doorway. Of course, Ralph knows what telex operation means. Aircraft can have higher performance, but at the same time, telex operation is also quite complex.

Eagle is now only on the F-16, which has realized telex operation. At the same time, it is still in the test flight and dropped several planes.

When Qin Guan exchanged this super-7, there was a vertical telex. However, when it was produced in 1132 factory, it was changed to a conventional hydraulic control because of its great difficulty. Even if it was a test flight performance for the holy people, it was also hydraulically controlled. However, Qin Guan had to add a digital telex to it according to the later project.

"Is it analog?" Ralph asked.

The electronic system is divided into analog system and digital system. The analog system is quite simple and easy to implement. Even the Su-27SK uses analog telex and three redundancy.

"It's a four redundancy digital telex," Qin Guan said.

Just you? Ralph certainly doesn't believe it.

"We can invite our friends to have a look," Qin Guan said.

Because the super-7 only has digital telex in the vertical direction, it is easier to have the guarantee of test flight. In history, it first completed the Raptor's digital telex, and then simplified it and assembled it for the super-7. Now, it is the opposite. After the digital Telex system is well done, it first tested the super-7. Anyway, the super-7 has hydraulic backup. After everything is OK, it can be assembled for the Raptor.

Recently, I have been doing this. As for the problem of no engine, it is certainly an excuse. The brand-new f404 can be installed at any time.

Several technicians went up and opened the equipment cabin in front of the nose.

If it was a previous fighter, it didn't pay attention to maintainability at all when designing. It was necessary to maintain a subsystem or even disassemble the cockpit.

However, the current super seven fully follows the principle of convenient maintenance. In addition to the rapid disassembly of the engine, the front equipment cabin can also easily remove the functional plug-in boards.

Now, when the technicians opened the equipment cabin, Ralph's eyes widened.

What do you see?

It's a row of plug-in boards. Each plug-in board can be inserted or pulled out. This is the most convenient design. It has only become popular in the eagle country in recent years, but now, it's actually seen on this Han fighter. Has this been improved from the J-7?

Look at the airfoil and fuselage. It can be said that there is almost no connection with the J-7 except a name!

"Can we pull it out?" Ralph asked.

"Of course." Qin Guan was very generous and was meant for you to see.

Ralph pulled out one of them, about the size of two pieces of a paper, which was densely covered with various parts, but it was very different from Ralph's guess.

How to judge whether a circuit board is an analog circuit or a digital circuit? Of course, look at the above components. If it is an analog circuit, there will be a large number of transistors, capacitors and resistors. If there is an old semiconductor radio, take it apart and have a look.

Digital circuits are almost all integrated blocks. Each integrated block has dense pins. Accordingly, those lines on the circuit board are also dense, and many are arranged neatly.

Now, what Ralph sees is neat lines, integrated blocks welded on them, and discrete capacitors and resistors, but the number is quite small.

This is a digital circuit, no doubt, and I have never seen the integrated block on it.

In particular, the integrated block in the middle looks very big. There are dozens of pins around it!

"What's this?" Ralph pointed to the integrated block and asked others. Although it's large, it doesn't have many functions. Even because it doesn't have enough functions, it has to be so large.

"This circuit board is a part of our integrated avionics. It is used to process data for the head up display. This integrated block is the processor inside. Because we don't have a special processor yet, we use a godson-1 for the time being," Tu explained.

Now, when the Han and Niu countries cooperate to transform the new J-7, that is, the historical J-7 M model, they have introduced the head up display synchronously.

The emergence of head up display is a bridge for the progress of aviation technology in China. It is very advanced at first sight. It directly superimposes the synthetic data and displays it in front of the pilot, which is also the premise of vitrified cockpit.

However, the performance of the head up display used on the current super seven has long exceeded that of NiuGuo avionics. It is almost copied from later products. Because it is digital processing, in order to have strong processing power, it simply adopts Godson 1 directly. The computing power of this chip can be said to be the first in the world.

Meanwhile, when he heard Godson one, Ralph suddenly understood something.

Yes, the Han people want to build their own avionics. They have their own technical reserves and ability!

When the world's electronic technology began to develop, Han was almost synchronized with foreign countries, and the gap was not large. However, after ten years of catastrophe, there was no development at home, but foreign countries were advancing by leaps and bounds, which opened the gap and could no longer make up for it.

Now, the emergence of Longxin 1 has surprised the world. In those ten years, the Han people have not given up and continue to engage in research. Moreover, they have made breakthrough progress!
