"The superiors asked us to improve our project within these two months." On the return train, Song Lao and a few people had already started to work.

"This time we only have fifteen minutes, and next time we go, we can finally complete our project report." Qin Feng was also very happy and said to Song Lao.

There are a lot of things to be perfected, this time it is just a hollow theory, what medium-range interception, what static and unstable layout, next time, we will use specific data to illustrate, static and unstable layout, so how high is this unstable degree? how to coordinate and control the aircraft safely, and so on.

This requires a lot of data calculation, and this time, we need to mobilize the strength of the entire 611 Research Institute!

It just so happens that the mapping and copying of the MiG-21MF has been completed, and it is waiting for the 132 factory to produce it, and after the production is completed, it is necessary to continue to find problems in the test flight.

Although the J-9 project failed, now, if this project can go on, it is equivalent to the J-9 has been reborn.

In the past, the emphasis was on high altitude and high speed, but now it is excellent fighting ability, in the layout of the canard wings, these can be reflected, but further modifications must be made, the shape of the main wing, the determination of the size, the position between the canard wing and the main wing, etc., Song Lao has been impatient, and wants to immediately pounce on the development of the new J.

At present, there is still no code name for your own project, and it is called Xinjian for the time being.

"Old Song, I think that for the convenience of the next explanation, we had better make a model." Qin Feng said.

Model? Hearing Qin Feng mention this, Song Lao said: "The model you landed on the train has already been sent to our institute by comrades from the railway department, and the capital can't catch up, so if you go back, you can get the model." ”

Qin Feng shook his head: "No, Old Song, that model of mine is made of wood, it looks rough and not modern, we want to make a sensation, it is best to make a new model." ”

New models?

Is this thing that important? At this time, Song Lao hadn't realized Qin Feng's true thoughts in his heart, and he only felt that it was just a model, and it didn't seem to be too necessary.

"We went to participate in this finalized review meeting, and we can see that 601 has done a great job, their various wall charts, and the big model, which makes people see the aircraft at a glance, triggering associations in the depths of their minds, and we also want to achieve this effect, so that our model can be accepted by everyone."

Qin Feng said this, and Song Lao nodded: "But, what's wrong with that wooden model?" ”

"It's wooden, it looks too dirty." Qin Feng said: "We want a sensational effect, we want everyone to look at this model, very interested in it, wooden, too common, how about we make one with aluminum alloy?" ”

Aluminum alloy will have a metallic texture and look more real, hearing Qin Feng's words, Song Lao nodded: "However, if you are aluminum alloy, it is not easy to process." ”

Although the fighter is made of aluminum alloy, it is in the factory, and it is not easy to process a small model, whether to use a whole piece of aluminum ingot, or to use a piece of scrap?

The whole block, too wasteful, high cost, the current 611 Institute, it would be good to be able to pay wages to the workers, but there is no extra money to do this.

If you use scrap, it's not easy to process.

"There it is!" At this moment, Qin Feng opened his mouth and said, "We use plexiglass!" ”

Plexiglass, whose chemical name is polymethyl methacrylate, is a polymer compound polymerized from methacrylate. The surface is smooth, colorful, small specific gravity, high strength, corrosion resistance, moisture resistance, light resistance, good insulation performance, and good sound insulation. It can be divided into three types: shape, rod and plate.

In 1927, chemists from a German company heated acrylates between two glass plates, and the acrylates underwent a polymerization reaction to create a viscous, rubbery-like interlayer that could be used as shatterproof safety glass. When they polymerized methyl methacrylate in the same way, they got a plexiglass plate with extremely good transparency and other good properties, which is polymethyl methacrylate.

Encouraged by this discovery, in 1931 the German company built a factory to produce polymethyl methacrylate, which was first used in the aircraft industry, replacing celluloid plastic for use as aircraft cockpit covers and windshields.

Until now, the transparent cockpit used on fighters is still made of plexiglass, and at the same time, there are many applications in automotive glass.

So, it's easy to find the scraps of plexiglass, and it's easy to process.

Ordinary glass will be broken at the slightest touch, but plexiglass will not, it can be sawed into various shapes with a hand saw, and it can be drilled with an electric drill, of course, in later generations, with a computer engraving machine, it is easier to carve a variety of beautiful patterns.

Now, with plexiglass, it looks absolutely high-end and easier to attract attention.

Of course, there is another advantage, even the current Qin Feng didn't expect that when Song Lao was making a report with this model, Song Lao had an idea and put this model directly on the projector, and as a result, on the screen, a beautiful duck layout fighter was clearly enlarged, and it conquered everyone at once.

A beautiful plane must be a good plane. This sentence is the famous aircraft master Dassault, in reality, it is almost like this, it looks beautiful, the first is the Su-27, (personal opinion), the second is the F14, these are beautiful aircraft.

Of course, there are also ugly good planes, such as Ferkang's big nose, which looks like a big tumor, but everyone wants it with envy.

And this canard layout fighter of your own side will definitely be a beautiful fighter, and this beauty has to be reflected through the model.

Hearing Qin Feng say that plexiglass was used, Song Lao was also overjoyed: "That's right, I'll do plexiglass, Qin Feng, this task will be handed over to you!" ”

The wooden model last time was actually made by Qin Feng, Qin Feng's three-dimensional thinking ability in his brain is very strong, and he can easily imagine the two-dimensional plan on the drawing as three-dimensional, this time, since he still has to make a model, he simply continues to hand it over to Qin Feng to do.

Now this matter is very important, and the research and development of military aircraft in China in the future, what path should be taken, depends on the efforts of the past two months, so this task, Qin Feng must go next, Lao Tu there, just grieve first.
