Chapter 1351

Since it is a world leader, it can form a monopoly in this field. Since it is a monopoly, the price will follow China's desire to take off.

Of course, according to the rules of China's take-off in the past, these arbitrary pricing are basically based on the external, while the internal pricing is based on the legal framework and basic code of conduct in the cabinet. Because of this, although the price of ty-22 stealth UAV is high, it really doesn't cost any more.

Say nothing else, but the ty-22 stealth drone focuses on the streamlined and round wing body fusion structure that envelops the engine.

Four cabin openings should be reserved for the inspection and maintenance of relevant equipment. The rest should be completely integrated with the flying wing fuselage without any trace of connection or exposure, so as to ensure the basic aerodynamic layout structure and stealth efficiency.

Because of this, the large-scale structural parts need to be completed by integrated manufacturing.

Not to mention the use of the second generation of composite materials used in the three-dimensional braiding machine, even with the most traditional metal materials, it is not easy to make large-scale special-shaped structural parts integrated with the flying wing body.

It not only needs precision forging, but also needs at least seven axis and five connected high-precision machine tools for detailed machining.

This does not include the details of heat treatment, flaw detection and compensation processing in the manufacturing process. Not including the materials, the cost of processing has already reached an appalling level.

If the use of carbon fiber composite materials, slightly simpler than machining, but need five axis automatic wire laying machine and special mold, and processing this kind of abrasive and without five axis machining center, so calculate down the processing cost of carbon fiber composite materials is not much.

What's more, the curing of the subsequent high-temperature heating furnace is also a large cost. The precision cutting and repairing after curing also need precision professional machine tools to complete, and the total cost is only high compared with machining.

It is not the same to use the dl-535 three-dimensional braiding machine developed by China Tengfei to manufacture this kind of large-scale special-shaped structural parts, because the dl-535 three-dimensional braiding machine uses the basic principles of the textile industry to produce a prefabricated part with high accuracy. After that, it only needs a basic mold and uses epoxy resin to complete curing under a certain temperature and pressure.

After that, we only need to open a hole in the predetermined position and cut immediately. Compared with metal and general carbon fiber processing, the cost is about 25% lower.

If not, it is impossible for ty-22 stealth UAV to reach 600 million yuan, and at least it will have to increase by 30% to reach the profit balance point.

Of course, the above is just an ordinary large special-shaped structure. Ty-22 is positioned as a stealth UAV, so in terms of manufacturing, stealth is taken into account.

It is obvious that metal machining and automatic laying machine of common carbon fiber composite materials can not complete this task, but dl-535 three-dimensional braiding machine of China's take-off can.

Because China Tengfei controls 12846 hexagonal wheels on dl-535 three-dimensional knitting machine and 84000 carbon fiber yarn carrying spindles to work together through a complex program system, among which the hexagonal wheels can rotate freely at 60 degrees, 120 degrees, 180 degrees, 240 degrees, 300 degrees and 360 degrees, so as to control the speed and length of yarn carrying around.

In this way, under the action of 12846 hexagonal wheels, 84000 spindles can be woven into the complex weaving method developed by China Tengfei according to the program, so that the produced composite material has strong radar specular reflection ability and internal radar scattering and cancellation effect, and finally completes the stealth effect of radar wave.

If you want to control the 12846 hexagonal runners and 84000 spindles, not to mention the complexity of the program, but the computer used for intervention needs strong computing power and redundancy, which is also impossible. The carbon fiber weaving method of China's take-off research needs high accuracy, and the slightest internal error will affect the local stealth effect.

Not only that, in different parts of the aircraft, due to the strength of the radar wave, there will be different strong and weak reflection areas in the reflection, so it needs to be treated differently.

For example, in the transition section of the wing body fusion surface, the formation of vortices may increase the emission probability, so the material braiding in this part needs to be strengthened for stealth, so the braiding production method is naturally different from other parts.

And these differences are extremely complex calculation process on the computer. Just because of this, the general computer can not be competent for such a large and complex manufacturing process. Only the supercomputer with greater computing power and higher redundancy can be competent.

For this reason, China Tengfei ordered four Dawning-2000 II supercomputers developed by the Computer Research Institute of the Chinese Academy of Sciences, with a peak computing power of 111.7 billion times per second.

One is set up in Aeroengine manufacturing base for Aeroengine development and data test analysis.

One is used to upgrade jsnb-iv aerospace industrial design system.

Test and data analysis of a supersonic warhead and ramjet engine.

The last one is equipped with dl-535 three-dimensional braiding machine, which is used for the production and manufacture of special stealth composite materials.

For this reason, China Tengfei zhuanmo has spent a huge sum of money to build a high-level production plant for the installation of the huge dl-535 three-dimensional knitting machine and its supporting Dawning-2000 II supercomputer. The total investment in light civil engineering is more than 1.2 billion yuan. If the Dawning-2000 II supercomputer, dl-535 three-dimensional knitting machine and complex programming software are included, The total cost exceeds 10 billion yuan.

Such a large investment, such a complex process, the implementation of the product end can be cheap.

What's more, is 600 million RMB expensive? As long as the U.S. military has something to do with stealth, which does not exceed $100 million? If 600 million yuan is converted into US dollars, it will be about 80 million US dollars at today's exchange rate, which is the price of the top F-15. Is that expensive? I don't know if I have a conscience.

Therefore, it is only for domestic use. If it can be sold abroad, Zhuang Jianye will directly change the RMB behind 6 into US dollars, which is called open robbery.

Of course, if the next generation of domestic combat aircraft can be mass produced in the future, and the new bomber can be successfully developed, the huge demand will naturally dilute the high production cost of dl-535 3D knitting machine. Then it will be the time for dl-535 3D knitting machine to really show its talents. Now it is just a small fight.

Even in some cases, it can't catch up with the first generation of dl-520 and the second generation of dl-527 in high efficiency. After all, these two generations of 3D knitting machines have been widely used in the production of satellite, missile shell, rocket engine tail nozzle, helicopter and small aircraft's main structure by China's take-off. It's because of their wide application and the characteristics of 3D knitting process itself to simplify the production process, That's why the high price of kinetic energy interceptors of anti missile missiles will be brought down.

So that lyj-18 can have a high level Kinetic Energy Interceptor no less than the world level at the price of 8 million RMB!
