Chapter 1612

"This is our first appearance of the J-10, so we specially invited Chen Rui to bring the performance of the J-10 to the limit, and also carefully designed a set of actions for him," said Song.

At this time, I began to talk about the contents of the air show. This air show was carefully planned by Qin Guan to show the progress of the Han country in the aviation industry. At the same time, it was also to add bricks to the export of fighter planes. It was expected that the J-10 would participate in the exhibition.

Now, Qin Guan stood close and looked at the fighter.

The air inlet under the belly is still a bulging air inlet. In addition to the J-10 of the Spey engine version, which uses the air inlet of the adjusting plate, the F110 engine version has been replaced with this bulging air inlet. The biggest advantage is to save weight.

"We have further optimized this drum," said Song. "Now, this inlet saves nearly 200 kg of weight, but there is no decline in performance. High altitude and high speed are still its strengths."

"Really? That's great," said Qin Guan.

This drum air inlet is a way to save weight. However, it is said that its performance is not as good as the adjustable air inlet, but it is simple and convenient.

For example, it optimizes the transonic range, but it doesn't work in terms of high-altitude speed. In the design of the J-10, high-altitude speed is an important indicator. After all, a very important mission is to intercept bombers. It is different from the bomb truck of the F-16.

"Thanks to the advanced computer system provided by you, we have carried out further optimization calculation and obtained the current scheme," said Song.

This requires complex hydrodynamics calculation, which is impossible without advanced computer. It is required to accurately simulate the flow field in DSI inlet, front fuselage, inlet section and pipeline, and further optimize the flow field through the observation of the calculated flow field map.

Now the J-10 is finally mature! Qin Guan sighed in his heart that if it is further developed, it is its engine.

This is not to say that the three generations of engines are not good. After several years of development, our own engines have gradually entered service. They have been in service in small batches, exposed problems, and then modified. Although this road is very difficult, it has come after all. On the basis of thoroughly understanding F110, the next generation of engines need to be self-developed.

Now, vector propulsion is the one that our side still lags behind or has not started. This requires modifying the nozzle at the tail to become a vector nozzle. This is a standard for the super mobility of the fourth generation aircraft, and vector propulsion is required.

In terms of vector, the nozzle of the Pegasus engine of the Harrier fighter can rotate, which is vector propulsion. However, this is different from what is needed. After all, this is only a means to meet the vertical takeoff and will not really affect the mobility.

After the fighter is equipped with a special vectoring nozzle, the maneuvering action can be controlled not only by the rudder surface, but also by the engine. In this way, the maneuverability can be greatly improved.

Later, the J-10 was equipped with a vectoring nozzle to perform Cobra and falling leaves. Even the movement of Cobra was smoother than Su 27.

At present, there is no such technology. If the vectoring nozzle can be made and integrated with the flight control, the mobility will rise to a higher level. As for now, it can only perform some conventional actions.

Of course, in this era, MIG 21 is still the main equipment of many countries. Now, the basic movements of the J-10 show are enough amazing.

Qin Guan stood in front of the J-10 meditating, and the others shut up. They knew that Qin Guan must be thinking about something now. Maybe it's about how to continue the development of his own aviation industry.

There is no end to this. When the third generation aircraft comes out, there will be four generation aircraft. Now our side is working on the fourth generation aircraft, and when the fourth generation aircraft comes out, there will be five generation aircraft, that is the era of UAVs, or air-space integrated aircraft.

Now, those are still far away, but if there is no advanced high beam, you don't deserve to be a policy maker.

Just then, suddenly, Qin Guan frowned.

The air show hasn't officially started yet, so it's under martial law for the time being. Not ordinary people can come in. Only the organizers and exhibitors can come in, but now there's a guest outside.

This man can't get in yet, but he's been wandering outside all the time. It's like coming for intelligence. Now, the security guard has noticed this man. If he doesn't leave, he may be driven away.

However, Qin Guan knew that this man was not a spy. She came here just to find someone.

Kelly.

Last time I went abroad to participate in the air show, I saw the female pilot of the red arrow flight performance team for the first time. What's more, the female pilot fell in love with Chen Rui at first sight, because Chen Rui saved the girl regardless of her life danger.

Later, several encounters showed that fate was really unstoppable.

Therefore, Qin Guan was aware of the crisis and simply made human intervention to force Chen Rui to marry Lin Xiaoxia. It was not until Lin Xiaoxia was pregnant that he ended this compulsion. In the past, he was definitely a typical representative of arranged parents.

Now, is this Kelly looking for Chen Rui or coming to the air show? She must have guessed that Chen Rui was at the air show? So, do you want to let her in?

"There's a girl outside. We used to know each other. Do you want to let her in?" Qin Guan still handed over the decision to Chen Rui.

"Who?" Chen Rui asked.

"Kelly, the female pilot of the flying performance team," Qin Guan said.

Chen Rui shook his head: "what does this have to do with me? If she wants to come, go through the formal formalities. If she should come in, she will come in naturally. If she shouldn't come in, don't make an exception. By the way, I'm going to call Xiaoxia."

Chen Rui said, stepping back, leaving old song and others looking at each other. What's the matter with Chen Rui? I haven't seen him like this before!

"Dad, Dad, wreath!" just then, Chen Yutong and his children had woven a wreath. Ruoxi ran over with the wreath and put it on Qin Guan's head.

"Well, dad is the most handsome!"

In the back, Yusheng also held a small flower in his hand and showed a smiling face there.

"Eh, why did uncle go?"

At this time, it was already sunset. The sun pulled everyone's shadow for a long time. Ruoxi pouted and looked at the back of his uncle's departure.
