The last small order, which can be regarded as a gesture of heart, gave this trip to the Feinborg Air Show a happy ending.

Bidding farewell to the seeker bidding project team still stranded in the UK, Yang Hui walked into the waiting hall with everyone and prepared to board the plane and return to China.

When the flight took off, scorching exhaust fumes were spewed out, Yang Hui went one step closer to returning to the Republic and sorted out the results of his trip to Europe:

First of all, the model airplane business has been pushed to a peak again, enriching the model airplane product line; The new Super J-7 has successfully attracted attention at the air show, although there are not many orders, but there are many countries that pay attention to the Super J-7 and Super J-7, after the finalization and launch.

Yang Hui has reason to believe that the second-generation fighters can be retired in the 90s, and it is not impossible to win some orders in the bidding for the new generation of fighters in various countries, and it is not impossible to grab some orders for the F16, and some countries that buy the F16 are not in urgent need of this kind of sky-high fighter compared to the second-generation aircraft.

The medium-range missile project of the Super Seven fighter has also improved, and the Republic will be able to have a reliable medium-range missile after 89 years, which is a very important point.

As for the computer project that Yang introduced to Lao Jiang, Yang Hui has nothing to worry about, and he can't manage it yet. It still depends on what the Ministry of Electronics Industry plans, and it really can't be done in the future, and the processor of the on-board computer can also be done directly in the laboratory, and the cost is higher.

To sum up, this time I went back to urge to speed up the progress of the super Jianjiao-7 at the base, and strive to fly the plane at the next Paris Air Show, and then there will be the most intuitive advertising effect.

Calculating, it has been almost five months since the first flight of the Super Jianjiao-7, and the engineering test aircraft should be completed. The second batch of test aircraft is about to fly and is ready to be transferred to the Yanliang Pilot Test Institute.

Super seven is the project, I am afraid that it has been rolled out in the early stage. As for the current aerodynamic designers of the Super Annihilation Sect VII, I think they have already left their hands free. Yang Hui has been planning a new aerodynamic exploration project for a long time, and it should be ready to start.

The plane landed in the imperial capital, and got on the plane back to the base non-stop, now the time is really precious, this money still does not need to be saved, although it is a transport plane of the Air Force, the noise is touching but also good, much faster than the train.

When I returned to the base, I saw that the test flight of the Super Jianjiao VII was in full swing, and having money was different. If it is like before, only the domestic army gives money, then the new aircraft really does not know that it will be tested until the year of the monkey.

"Oh, you're coming back, how much the air show has gained, we're all happy to say it."

Originally, Chief Engineer Yu had known about the harvest of this air show on the phone for a long time, but now he still asked, and everyone was happy to say it.

Announcing good things, Director Bai still likes it. The progress of the air show was immediately announced.

"We have a very good harvest at this air show, with orders from Pakistan and Saudi Arabia for 60 aircraft, as well as two orders from Zimbabwe, and we should be proud of the new aircraft that is still in the development stage."

Ooh. I see, there are more than 60 export orders for our new aircraft, and now the export sales of the J-7 are no more than that. This shows that the potential of Super Annihilation VII is huge.

Think about that, designers. The morale of the test pilots was high, and the orders were received. Now we are waiting for the finalized test flight of the new aircraft, and there is not much time left for everyone.

After the good news was announced, Chief Engineer Yu was also satisfied, and greeted all these cadres and returned to their respective posts to continue to work on the project.

Everyone dispersed, Yang Hui followed next to the chief engineer and inquired about the progress: "Chief master, our current aerodynamic layout design has been decided, right?" If I can free up manpower, then I am ready to call in these aerodynamic designers to explore a pneumatic solution, which is very important. ”

Hearing Yang Hui say that he wanted to explore a new aerodynamic layout, this aroused the interest of Chief Yu, and the aerodynamic layout of the Super Annihilation Sect VII was proposed by this one, and led the team to come up with aerodynamic data.

The final facts also proved that Yang Hui's pneumatic scheme is indeed very good.

The low-altitude and low-speed performance of the Super Jianjiao 7 is indeed good, and the high-speed performance has also been retained, and the front and rear cockpit vision is much better than the previous old scheme.

Now that he hears that there is a new pneumatic scheme, the chief engineer will naturally be curious: "'Oh, what pneumatic scheme, say it and let me listen, your aerodynamic skills are very solid, if it is feasible, now with our current financial strength, it is not impossible to explore a new pneumatics." ”

Chief Engineer Yu asked about this project, Yang Hui didn't intend to hide it, just say it, it's okay to say it, there is nothing to keep secret, this pneumatic design has no predecessors, and it can also be said that there is no one to come, but this design is indeed feasible.

In the eighties, it was just right to put forward the use, and in the mid-to-late nineties, this pneumatic scheme would no longer have a market, after all, this scheme has many advantages, but the limitations are still quite large.

Seeing that everyone had already left, Yang Hui simply sat on the rostrum with Chief Master Yu, looked around without looking for a pen and paper, and finally could only reach the idea on the notebook next to Chief Master.

He said ill-intentionedly: "Chief Master, borrow your notebook for use, and I'll draw a schematic diagram." ”

Hearing that he was going to use his notebook as a draft book, Chief Master Yu felt distressed for a while, and then thought about the Super Annihilation Sect Seventy-Three View that Yang Hui simply drew last time.

Chief Master Yu was suddenly stunned again, and simply handed the notebook to Yang Hui, waiting to see what new technical ideas Yang Hui would have.

Take Chief Yu's notebook and turn to the last page, and take a pen to write and draw on it:

The first thing that was drawn was the delta wing layout, which is normal, but this is not a double delta wing layout, it seems that this new aerodynamic design has little to do with the Super J-7 or even the Super Seven.

Then Yang Hui was behind the cockpit, and the front surface of the wing was painted with a small wing, needless to say, this combination is now the hottest and most mainstream duck aerodynamic layout in the world, but after thinking about it carefully, I feel that it is wrong, Yang Hui, this kid, should know that the domestic duck aerodynamic layout is 0611 in research, right?

The base repeats the study of the duck aerodynamic layout, which is not only a serious waste of money, but also a waste of manpower and material resources, and is suspected of robbing with 0611, now the base and 0611 cooperate to do super seven, it is still harmonious, Yang Hui will not be so ignorant of the overall situation, right?

"Duck aerodynamic layout, Yang Hui, we haven't studied this, and now we are rashly studying this, I'm afraid it's not good?"

Chief Engineer Yu said very tactfully, but as soon as he heard it, he knew that Chief Engineer Yu would not support the duck aerodynamic layout, and of course Yang Hui did not plan to study the duck aerodynamic layout.

The technology that Yang Hui wants to study is only in the canard pneumatics, and the advantages can be played better, and the new technology is more suitable for the canard pneumatic layout.

Therefore, Yang Hui calmly replied to Chief Engineer Yu's words: "Yes, Chief Engineer Yu, I don't plan to repeat the study of the canard aerodynamic layout, the technology I want to study is only more suitable for the aircraft with the canard aerodynamic layout, and it can also be used in other models." ”

After speaking, Yang Hui picked up the pen and began to add the most important things on the schematic diagram, the previous drawings are just foreshadowing, just green leaves, and now is the point.

There will be a lot of hardpoints on the wing of the aircraft, and the strength is generally the greatest in the place closest to the fuselage, so the hardpoint here is the replanting hardpoint, which is on the upper surface of the wing at the same position as this heavy-duty hardpoint. Yang Hui drew a few strokes, and at first glance, Chief Master Yu thought that he had drawn a winged knife.

It's really a retro idea to install a wing knife on the delta wing layout, I really don't know what happened to Yang Hui, how to go against the current, when the world trend has given up the wing knife, Yang Hui actually wants to go the other way, what's wrong with this kid recently?

However, is Yang Hui's painting really a winged knife? Will Yang Hui be idle to engage in this kind of thing? Obviously not like this, Yang Hui has his ideas. (To be continued......)
