"This is generally the case, when we carried out theoretical exploration of side plate aerodynamics, we analyzed the advantages and disadvantages of using side plates in the canard aerodynamic layout aircraft together with the designers of 0611, and deeply studied the principle of action of side plate technology, and summarized and summarized."

As always, Yang Hui was led to Liu Jun, and Liu Jun, who now knows the most about side plate technology, is not as familiar with Liu Jun's side plate technology as Yang Hui, the original person who mentioned side plate technology.

Naturally, Liu Jun also gave Yang Hui an introduction to the general situation of the side plate technology, Yang Hui took the overall technical outline of the project, and the successful exploration of the side plate technology by the pneumatic design team for several months was condensed in this dozens of pages of report.

The more I looked, the more frightened Yang Hui himself did not expect that the original side plate technology was not just as simple as Yang Hui thought, in his last life, he only roughly listened to the legend of the side plate technology, and only knew that the side plate and the duck pneumatic are the most compatible, but the reason why the fit depends on the theoretical analysis data in hand.

Not much to say directly to the technical data snippet:

Fundamentally, we found that side plate technology is not suitable for all canard aircraft.

The basis of the side plate technology is to use the detached vortex generated by the canard wing, and maximize the use of its detached vortex, so that the vortex can flow more smoothly through the trailing edge of the main wing, so as to solve the problem of torque nonlinearity.

The canard aerodynamic layout of the aircraft is just a general term, and there are different methods for the layout of the canard wings, including short-range coupling, medium-distance coupling, and long-distance coupling, and different canard aerodynamic layout schemes. There will be different emphases.

The close-coupled canard aerodynamic layout creates the largest and greatest number of favorable vortices flowing through the leading edge of the main wing. Significant improvement in lift and maneuverability, which is most suitable in conjunction with side panel technology. The basis of side plate technology is the eddy current that rectifies the flow through the trailing edge of the main wing surface, and only when there is enough vortex at the trailing edge of the main wing surface, the role of the side plate technology can be maximized.

The long-distance coupled canard aerodynamic layout is completely different, the long-distance coupled canard is far away from the main wing, and the main role is to solve the problem that the pitching moment of the tailless delta wing layout is too short. It does not produce a detached vortex that can act on the leading edge of the wing, and the vortex generated by the long-coupled canard does not reach the surface of the main wing, so there are not many vortices on the surface of the main wing, and the addition of side panels is almost meaningless.

Medium-range coupling is somewhere between long-range coupling and short-range coupling, and the advantages of robustness are both. However, the two points are not prominent, and the vortices that can reach the surface of the main wing in the medium-distance coupling are not as much as those in the close-coupled canard layout, so the effect of the medium-distance coupled canard is still not as good as that of the close-coupled canard after using the side plates.

After reading the origin of the side plate and the canard pneumatic layout technology, Yang Hui is clear about the relationship between the side plate technology and the canard pneumatic layout. It can also be regarded as understanding why the CY1 verification machine, which used side plate technology in the previous life, is a close-range coupled canard aerodynamic layout redesigned on the basis of the Shanying training aircraft.

Rather than directly installing side panels on the 0611 Project 10 aircraft to verify the side plate technology, for no other reason than because Project 10 uses a medium-range coupled canard aerodynamic layout, which does not fully reflect the full advantages of the side plate technology.

Thinking of this, Yang Hui had some doubts about whether 0611 was willing to use side plate technology on Project 10, after all, it seems that the side plate technology and the No. 10 project with medium-distance coupling canard pneumatic layout are not the most harmonious.

The worried Yang Hui began to be a little worried about the plan to intervene in the No. 10 project this time, which was manifested in Yang Hui's face and began to smash his mouth. There are many things to reconsider.

Liu Jun is the head of the side plate technology research group hand-picked by Yang Hui, and he naturally understands the side plate technology in the process of cooperating with 0611. At first, 0611 was also very interested in the side plate technology of the base.

Even 0611 disclosed the specific situation of Project 10 to Liu Jun, but the results of the final theoretical analysis did make 0611 a little entangled, and even now 0611's cooperation in side plate technology is not as strong as at the beginning.

"Secretary-General Yang. That's the case, you want us to work with 0611 to explore the combination of canard pneumatic layout and side panel technology. I think you also know about Project No. 10, and 0611 began to study the aerodynamic layout of Project No. 10 very early. They are very adamant about the mid-range coupling layout, so we have some opportunities to work with 0611 later."

Technicians are like this, they don't care about other intuitive technologies, they can say whatever they should say, and they don't care about Yang Hui's entanglement and unwillingness in his heart now.

A good side plate technology was originally a very good invention, but it was too late to be researched in the previous life, and it was born at the wrong time.

Think carefully about what this should be, whether to continue researching, or not

Really unwilling, sitting in front of Liu Jun's desk, Yang Hui carefully thought about whether there was any other way to live in the side plate technology.

Seeing Yang Hui, a usually very strong and capable leader, now racking his brains for the side plate technology, Liu Jun also had a rare comfort.

"Secretary General Yang, this is nothing, the east is not bright and the west is bright, the side plate technology of Project 10 is not suitable for us, there are other ways to live, and the side plate technology does not have to be hanged on the tree of Project 10."

After listening to Liu Jun's comfort, it was a little better, but thinking that the side plate technology could not be applied to the No. 10 project, Yang Hui's series of follow-up plans could not be carried out. At least Project 10 will go back to the old path and take 18 years to sharpen a sword, and when the equipment is finalized, it will mean a generation behind the American fighters.

The most important thing is that the No. 10 project has embarked on the route of a lifetime, although it is the last time to come up with an excellent third-generation machine, but the telex system will definitely be as Yang Wei said last time: the national telex system manpower and material resources are heavily inclined to the three-axis four-redundancy digital telex, and the single-axis three-redundancy analog telex of the base cannot be localized before eight or nine years, and the taste of being stuck in the neck is not comfortable.

It would be best to force yourself to cheer yourself up and continue to read the technical outline of the side plate technology, and maybe you can see some other ways to survive from this.

Continue to look below, followed by some theoretical analysis of the combination of close-coupled canard aerodynamic layout and side plate technology, although there is nothing to look at, Yang Hui knows that there is no close-coupled canard aerodynamic layout aircraft in China, but seeing the tempting data is still unable to resist the temptation.

After looking at the details of the side panels and canard pneumatic layouts, a small summary is followed: from this we can theoretically conclude that the side plate technology is suitable for combination with close-coupled canard pneumatic layouts. In the end, the reason is that the side plate technology can play a powerful role as long as there is a strong vortex passing through the airfoil. In other words, it is not the canard aerodynamic layout that works with the side plate technology, but the vortex generated by the canard aerodynamic layout.

Originally, the side panels were coordinated with the vortex on the main wing, and the close-coupled canard layout was just a generator that generated the vortex.

It seems that this is the most in-depth and straightforward explanation, and Yang Hui suddenly has a new idea, which seems to have opened up a new world.

It is not only the canard aerodynamic layout that can produce the detachment vortex of the leading edge of the wing, but there is also another mainstream aerodynamic layout. (To be continued......)
