I have to say that after Sultan said hello, the preparations for the air show seemed to be quite smooth, and after everything was in order, it was time to wait for the air show to shine on the day.

The situation on the day of the air show is also very good, the most surprising thing for Yang Hui is that the air show team from Saudi Arabia actually came out of the air show, driving the Jianjiao 7A 7 aircraft formation on the opening day of the air show to fly a pretty good performance, this is indeed Yang Hui and even the Southwest Science and Industry did not know in advance, Saudi Arabia also used the Jianjiao 7A to do the air show, this

You must know that before this, Saudi Arabia almost did not have an air show team, and now it is definitely a major affirmation of the Jianjiao 7A to be able to form an air show team to fly Jianjiao 7A.

Yang Hui can imagine that after this time, Southwest Science and Industry may be able to receive an order for the Jianjiao 7A or the reduced version of the J-74 flight show aircraft from Master Bayi, which is a small mosquito leg order.

Dressed in formal Arabic robes, the beard moved as Sultan spoke.

"How about it, I didn't expect it, this is the Saudi Air Force air show team that I proposed to the king, Jianjiao 7A This aircraft has half of our Saudi investment, and we use this aircraft to do air shows, which is definitely quite a face-saving thing."

There was a strong sense of pride in his speech, after all, it was an aircraft invested and developed by Saudi Arabia, which must be proud, but of course there were shortcomings in it, which made Sultan feel regretful.

Yang Hui also saw the shortcomings of this Jianjiao 7A performance machine, but now it can be made up.

"Jianjiao-7A has good low-altitude maneuverability, and it is really good for air performances, the only drawback is that the turbojet 7 engine is not powerful. The good thing is that our turbofan 10 engine has been finalized. There will be another half a year to deliver the complete Jianjiao 7A, and the Jianjiao 7A at that time is the most suitable performance machine. ”

Sultan loved to hear what he said. Saudi Arabia has already prepared several plans, and the monkey version of the Jianjiao 7A used now must be eliminated. Perhaps it would be a good option to send these planes to Iraq.

"Okay, the new engine has been successfully developed, as long as we are sure that it is safe, we will change it, and some unnecessary equipment in this aircraft will also be dismantled for us, and Saudi Arabia must have a world-class air show team."

When the young Saudi air show team landed, the opening ceremony of the air show was completed, and there was nothing to say about the subsequent air show.

F16, F5, F4, these American-made fighters have flown many times, and the only thing that catches people's eyes is that the Tu-22 bomber from Iraq flew to the air show site and circled a few times. The appearance of this bomber really caused a sensation on the scene. It can also be regarded as the fact that Soviet-made aircraft were not absent from this air show, indicating the existence of the Soviet aviation industry.

Then the J-74 aircraft from the southwest science and industry flew up to do a flight show, after the landing gear was retracted, the whole machine looked not much different from the J-7A, but because of the installation of the turbofan 10 engine, the performance of the J-74 suppressed the limelight of the J-7A.

This also made Sultan more determined to replace the current Jianjiao-7A, and Iraq on the side saw the J-74 performing in the air, and his saliva was even more dripping, just by looking at this flight show, it can be seen that it is indeed much better than the Jianjiao-7A.

This also strengthened Iraq's confidence in the Jian-74 more and more. At this air show, it seems that the intention order for the 60 aircraft can be set, and it will not be too long before the final production is made.

In the indoor exhibition hall, two more booths were opened up next to the booth of Southwest Science and Industry, Hongdu on the left. On the right is Xifei, which occupies almost half of the exhibition hall, and the scale of the exhibition is quite large.

Now most of the eyes are on the Xifei booth. Even Southwest Science and Industry can only fall behind, and there are quite a lot of exhibitors brought by Xifei. It far exceeded the new regional airliner that Yang Hui had expected at the time.

See a slip of the model on the West Fly booth from this new regional airliner project. and then to the Yunqi plane, and even put out a Zhenguo artifact like the H-6, this time the westward flight can be said to be pouring out.

The most interesting thing is the introduction of the new regional airliner next to the staff, not only Tang Changhong, but also a group of Germans, about the new regional airliner on the side of the introduction of the display board, clearly written Sino-German cooperation project, MBB company is also written on the display board, it seems that the background behind this aircraft is quite deep.

Yang Hui became an observer once, and watched Xifei and MBB perform, at this time, MBB seemed to be much more skilled than Xifei, and he was also a veteran of many years of ups and downs in the business world.

Arabic with a Germanic accent is hilarious, but the specifics of this new regional jet are what everyone values, and Yang Hui listens carefully.

"As you can see, this new regional airliner is jointly developed by our MBB company and Xifei Company of the Chinese Communist Party, codenamed MPC75. It has a seating design of 68 to 83 seats and will be used for direct flights between medium-sized cities"

MBB's introduction seems relatively weak, after all, the design of the body is mainly responsible for Xifei, and it ended soon after roughly brushing the sense of existence, and handed over the topic to Tang Changhong.

Tang Changhong, who took over the conversation, knew that the introduction of the MBB staff just now was not technically exhaustive, so he mainly introduced the advanced points of the new linear compared with other linear passenger aircraft.

"Our aircraft uses the 3+2 layout that only mainline airliners like the B737 use, which is much more spacious than the common regional airliners now; Equipped with a large-channel ratio turbofan engine, the new engine uses gearing technology to deliver unprecedented ultra-low noise, which is only two-thirds of the average turbofan engine of today, which will bring a new ride experience. ”

Since Southwest Science and Industry has not yet come up with the finished engine this time, Tang Changhong is not entangled in the issue of the engine, and directly leads the topic to the shape design of this aircraft.

This is all the effort that Xifei has put into this aircraft, using international advanced technology and some unique designs.

"Our aircraft adopts many international advanced technologies in the design, the most prominent is the supercritical wing design, which will significantly the flight performance of the aircraft, reduce flight resistance and provide better attitude control performance, which is the most cutting-edge wing aerodynamic design in the world."

Speaking of this, Tang Changhong was proud, this technology is what Tang Changhong has been studying in college, and after arriving in Xifei, using Xifei's scientific research equipment, especially after the old-fashioned computing formulas in Xifei, this has made relatively great progress.

It is precisely by virtue of this that Tang Changhong sat on the throne of the deputy chief engineer of the new regional airliner.

Hearing what Tang Changhong said, Yang Hui's eyes were about to fall off, this guy actually captured the supercritical wing technology quietly, this is simply against the sky, staring carefully at the MPC75 model, Yang Hui really found that this wing is indeed different and the most fashionable.

That's right, the supercritical wing is the most fashionable design of the year, and it is even more fashionable to use this thing on regional airliners, and this alone can blow other regional airliners.

Since the airshow was attended by aviation professionals, they couldn't believe it when they heard that supercritical wing technology was used on the airliner, known as the MPC75.

Originally, it was still a tall supercritical wing technology, which was used on trunk airliners before, but now after being conquered by these Chinese people, how did it become a cabbage price? Actually installed a regional airliner, can you give a little self-esteem to the high-tech supercritical wing (to be continued......
