Although Yang Hui's painting looks very much like a wing knife, but it is very different from the wing knife, this device is accurately called the side plate, with this canard pneumatic layout, this pneumatic layout has a new name: side plate canard pneumatic.

Side plate canard aerodynamic layout is a really buried technology, this technology in the last life is in 2002 to study out of the public, in 2000, this technology is embarrassing, it has no use, the most suitable for the use of side plate technology canard aerodynamic layout aircraft, in 2000 all have been finalized.

The European Twin Winds, Gripen fighters, and the Republic of China's No. 10 Project all entered the army in 2000, and it is somewhat redundant to install this new thing, because these aircraft use fly-by-wire flight control and static unstable design, which has achieved a technological leap and made up for the inherent defects of the canard aerodynamic layout aircraft.

Explain the technical advantages of fly-by-wire flight control: fly-by-wire flight control can replace the pilot to accurately control the aircraft, in order to adapt to the torque nonlinear characteristics of the aircraft, it is passive to adapt to the torque nonlinearity.

Fly-by-wire flight control cannot solve this fact, and even in later generations, the nonlinear characteristics of torque are still a worldwide problem, and the international aviation community still has no way to solve this inherent problem, which can be circumvented by fly-by-wire flight control.

The metaphor of the fly-by-wire flight controller solves the problem of nonlinear torque: it is like an ancient tree in the middle of the highway, and the driver of the car often has a high-speed car driver who can't react to crash into it, and now there is a trip computer instead of the driver, and the car is controlled to avoid the side and avoid the tree at this dangerous time.

Equally. The side plate technique is also used to compensate for the inherent defects of the canard aerodynamic layout, and it is also used to solve the problem of torque nonlinearity.

However, there is a fundamental difference between the two methods. Instead of using a trip computer to replace the driver to avoid risks, the side panel technology directly and cleverly avoids the tree during road construction design. Arrange this tree in the green belt in the middle of the road.

Not only is there no risk, but it also beautifies the road environment and isolates noise, which has many benefits.

The two ways of solving the torque nonlinearity problem represent two different ideas, one of which relies on electronic control technology and the other on the aerodynamic design of the hardware.

Regardless of the two methods, each has its own advantages. But why did the two same approaches end up with fly-by-wire flight control dominating all aircraft, while side panel technology is obsolete?

The reason is simple, that is, because the fly-by-wire flight control technology is the first to break through. Side panel technology was not discovered until 2000, and side panel technology is a hardware solution.

It had to be considered when the aircraft was first designed, but the technology appeared too late in later generations and failed to survive the overpower of fly-by-wire flight control.

Of course, there are many technical advantages of fly-by-wire flight control, such as programmability, different uses of an aircraft can be realized through different flight control programs, etc., so in the end, the fly-by-wire flight controller crushed the side plate technology.

This active control of the vortex on the surface of the wing and the transformation of decay into a magical side plate technology is now something that Yang Hui wants to study in advance. Of course, Yang Hui has no doubt about the excellence of fly-by-wire flight control technology.

However, at a time when the electronic technology of the Republic is not good, the use of this side plate technology can obviously speed up the progress of the No. 10 engineering machine, and it can be regarded as a new way.

The later No. 10 project had a development cycle of as much as 18 years. It was too long, so when the No. 10 project came out, it was already behind the F22 in the United States, and it failed to catch up with the third-generation aircraft replacement boom in the nineties. was almost squeezed to death by Su 27, which Yang Hui could not tolerate.

Now that he has been reborn, he has returned. Then we have to find a way to speed up the technology of Project No. 10, and now the base and 0611 are cooperating with more than seven. It is not impossible to meddle in the No. 10 project, so that this fighter for air combat can be made before 96.

Relying on Super Seven and J-8 to compete for air supremacy in 96, Yang Hui has no confidence, such an ultralight aircraft, and the second-generation aircraft is really unable to carry the girder in that place in 96, and the difference between light aircraft and ultralight aircraft is still quite big.

These problems made Yang Hui have to take out this side plate technology, with the follow-up flanks, Yang Hui has reason to believe that the new aircraft can reach the combat effectiveness of the No. 10 project in the future.

At the same time, the use of side plate technology, coupled with incomplete fly-by-wire flight control, the cost can be further controlled, the high cost of the No. 10 project in the later generations is also the reason for restricting the large-scale installation of the No. 10 project, the domestic third-generation aircraft replacement in later generations can not be replaced in the same amount according to the number of second-generation aircraft configuration.

The cost of control of a fighter like Project 10 is also a must be considered, and a set of fly-by-wire flight control system is the price of tens of millions. Using two side panels and a longitudinal fly-by-wire flight controller, the cost of Project No. 10 can be reduced by at least seven or eight million, and it can be done by saving tens of millions of dollars ruthlessly.

Of course, side panel technology also has its problems, on the one hand, it will increase the weight, but it is not too much; Its biggest problem is that the use of side plate technology will illuminate a large radar reflection source, which is also the reason why this thing was not seen in the later No. 20 project, and in the era of stealth fighters, side plate technology is even more unpopular.

Now it's different, first solve the problem of whether there is or not, as for the RCS value, the larger is the bigger, and then wait until the telex technology is mature, and directly remove this side plate in the modification of the No. 10 project.

Thinking of this, Yang Hui became more and more determined to take out this side plate technology, and it was much easier to work on pneumatics than on fly-wire in the eighties.

"Look, Chief Engineer, this is the project I intend to study, and I found this good thing in my research, which can actively control the unfavorable eddy currents on the surface of the wing and solve the problem of moment nonlinearity. This can be used on many of our aircraft, but the biggest use is the canard aerodynamic layout. ”

Hearing Yang Hui blow this winged knife so godly, Chief Master Yu wondered even more, what is this, where did it come from so magically, isn't it just a winged knife, although it is a lengthened winged knife.

"It's just an elongated winged knife, how can it be as amazing as you say, are you sure you want to study this?"

Unexpectedly, the side plate technology that he had been planning for so long was said to be a wing knife, and Yang Hui could only patiently explain the difference between the side plate and the wing knife.

"Chief Master, this side plate is very different from the wing knife, I admit that when I first started researching, I got some inspiration from the wing knife, but this is definitely not a thing, I write out these theoretical derivation data, you can see it."

It is really difficult to say that the theoretical problem can completely prove the feasibility of the side plate technology proposed by Yang Hui now, after all, this thing is original, and there is no experience in foreign countries, but Yang Hui can prove some problems from other aspects, which is enough to prove the role of side plate technology.

Sure enough, Chief Master Yu is knowledgeable, and he can understand the importance of this thing after only reading the part, but it is really possible to achieve the effect that Yang Hui said. Just rush this possibility, and you must verify it, this thing is too tempting, and I am really unwilling not to study it and figure it out.

"Okay, I can see the advanced nature of this thing, we have to study this technology carefully, it's too critical, this technology is too critical, this is definitely a worldwide original classic."

Hearing what Chief Master Yu said, Yang Hui didn't think it was an exaggeration, this side plate technology was really so powerful. In 2002, a private company that first researched this side plate technology was introduced, and they put this technology on the market and exhibited it at the Zhuhai Air Show, which shocked everyone, and none of the foreign experts saw the mystery of these two boards.

Now that this thing has been developed, as long as it is put into use in Project 10, it is original. Speaking of which, it is not a problem to rely on this technology to win an academician quota, the international original advanced technology has also solved the big problem in China, which is definitely sorry for this technology if you don't give an academician.
