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

Of course, these casual pricing is basically external and internal according to China Tengfei's previous rules, and internally, according to the legal framework and basic code of conduct. Because of this, although the price of 600 million yuan in stealth drones is high, it really does not cost a penny.

Not to mention anything else, the stealth drone is aimed at the streamlined round wing-body fusion structure that wraps the engine.

Four cabin openings are needed to be left for inspection and maintenance of relevant equipment. The rest must be fully integrated with the flying wing layout fuselage, and there must be no traces of connection or exposure. Only in this way can the basic aerodynamic layout structure and stealth efficiency be ensured.

Because of this, this large structural part needs to be manufactured in an integrated manner.

Not to mention the three-dimensional braiding machine used in the second generation of composite materials, it is not easy to make large special-shaped structural parts that are fused with the wing body of the flying wing body.

Not only does it require precision forging, but it also requires at least seven-axis and five-connected high-precision machine tools to be meticulously machining.

This has not yet counted the detailed work of heat treatment, flaw detection and compensation processing during the manufacturing process. If the materials are not included, the processing cost is already outrageous.

If carbon fiber composite materials are used, it is slightly simpler than machining, but it requires five-axis automatic wire laying machines and special-shaped molds. However, it is necessary to process such abrasive tools with five-axis machining centers, so the processing cost of carbon fiber composite materials is not much less.

What's more, the subsequent curing of high-temperature thermal furnaces is also a big cost. The precise cutting and refining after curing also requires precision professional machine tools to complete, and the total cost is only higher than that of machining.

It is different to use a three-dimensional braiding machine developed by China Tengfei to manufacture such large-scale structural parts, because the three-dimensional braiding machine uses the basic principles of the textile industry to produce a prefabricated piece with extremely high accuracy. After that, only a basic mold is needed and the curing is done with epoxy resin at a certain temperature and pressure.

Do not modify the mold in the future. You only need to open a hole in the predetermined position and cut it immediately. The cost is about 25% lower than that of metal and general carbon fiber processing.

If not, it is impossible for stealth drones to have 600 million yuan. At least it has to increase by 30% to reach the profit balance point.

Of course, what is mentioned above is just an ordinary large unusual structure, and its positioning is a stealth drone, so in terms of manufacturing, it is more than taking the stealth factor into account.

Metal machining and automatic silk laying machines for ordinary carbon fiber composite materials obviously cannot complete this task, but China's three-dimensional braiding machines can.

Because China Tengfei controls the 12,846 hexagonal rotors and 84,000 wound carbon fiber wire spindles on the three-dimensional braiding machine through a complex program system, the hexagonal rotor can perform free rotation of degrees and degrees, thereby controlling the speed and length of the surrounding spindle conveying lines.

In this way, under the action of 12,846 hexagonal rotors, 84,000 spindles can be weaved according to the program to create the complex weaving method developed by China Tengfei, so that the composite materials produced have extremely strong radar mirror reflection capabilities and internal radar scattering and offsetting effects, and ultimately complete the stealth effect on radar waves.

To control these 12,846 hexagonal rotors and 84,000 spindles, not to mention how complex the program needs to be, but the computer used for intervention requires extremely strong computing power and redundancy. There is no way to do this. The carbon fiber weaving method studied by China Tengfei requires extremely high accuracy, and the slightest error in the internal will affect the local stealth effect.

Not only that, in different parts of the aircraft, the strength of the radar wave will also show different reflection areas in the reflection, so it needs to be treated differently.

For example, in the transition section of the wing body fusion surface, since the formation of vortex may increase the emission probability, the material weaving of this part must be strengthened invisibly, so the weaving method is naturally different from other ministries and commissions.

These differences are extremely complex calculation processes on computers. Because of this, ordinary computers are simply unable to handle such a huge and complex production and manufacturing process. Only supercomputers with greater computing power and higher redundancy can handle it.

Therefore, China Tengfei ordered four Shuguang-2000 Type II supercomputers developed by the Institute of Computer Science of the Chinese Academy of Sciences, with the peak computing power reaching 111.7 billion times per second.

One is set up in an aircraft engine production and manufacturing base for aircraft engine development and data testing and analysis.

One is used to upgrade the JSNB-IV aerospace industry design system.

Test and data analysis of an ultrasonic warhead and fire engine.

The last one is equipped with a three-dimensional braiding machine for the production and manufacturing of specialized stealth composite materials.

To this end, China Tengfei spent a huge amount of money to build a high-grade production plant for the installation of huge three-dimensional knitting machines and its supporting Shuguang-2000Ⅱ supercomputers. The total investment in civil engineering alone exceeded 1.2 billion yuan. If the Shuguang-2000Ⅱ supercomputers and three-dimensional knitting machines and complex programming software were included, the total cost exceeded 10 billion yuan.

Such a large investment and such a complex one are only in the process, and it is only a hell that it can be cheap on the product side.

What's more, is 600 million yuan expensive? As long as the US military is involved in stealth, the one that does not exceed 100 million US dollars? 600 million yuan is equivalent to US dollars. According to the current exchange rate, it is only about 80 million US dollars, which is the price of a top-equipped F-15. Is this still expensive? I am so conscientious, okay?

So this is exclusively for domestic use. If it can be sold abroad, Zhuang Jianye will directly exchange the RMB behind 6 for US dollars, which is called an open robbery.

Of course, if the next generation of domestic combat aircraft can be mass-produced and the new bomber can be successfully developed, the huge demand will naturally dilute the high production cost of the three-dimensional knitting machine. That is the time when the three-dimensional knitting machine will truly show its strength, and now it is just a small fight.

At some point, it is even unable to catch up with the first and second generations of efficiency. After all, these two generations of three-dimensional knitting machines have been widely used by China Tengfei for the production and manufacturing of main structures of satellites, missile shells, rocket engine tail nozzles, helicopters and small aircraft. It is precisely because of its wide application and the characteristics of the three-dimensional weaving process itself to simplify production procedures, so the high price of the kinetic energy interceptor of the anti-missile missile is reduced.
