Take Off My Aviation Era

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

Of course, these arbitrary pricing are basically external according to China's previous rules, and internally, they are based on the legal framework and basic code of conduct in the cabinet. Because of this, the sale of TY-22 stealth drones is 600 million yuan. Although the price is high, it really doesn't cost a cent.

Not to mention anything else, but the TY-22 stealth drone stared at the streamlined round wing body fusion structure that wrapped the engine.

Four cabin openings are required for inspection and maintenance of related equipment, and the rest must be completely integrated with the flying wing layout fuselage without any traces of connection or exposure, so as to ensure the basic aerodynamic layout structure And stealth performance.

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

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

Not only precision forging is required, but also high-precision machine tools with at least seven-axis five-joint for meticulous machining can be completed.

This does not count the details of the heat treatment, flaw detection and compensation processing in the manufacturing process. If the materials are not included, the processing cost is already heinously high.

If carbon fiber composite materials are used, it is slightly simpler than machining, but a five-axis automatic laying machine and special-shaped molds are required, and a five-axis machining center is indispensable for processing such abrasive tools, so the processing cost of carbon fiber composite materials is calculated. It's not much less.

What's more, the subsequent curing of the high-temperature thermal furnace is also a large expense. The precision cutting and repair after curing also require 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 Ascendas to manufacture such large special-shaped structural parts, because the DL-535 three-dimensional braiding machine uses the basic principles of the textile industry to produce a highly accurate preform. Now, only a basic mold is needed, and the epoxy resin can be cured at a certain temperature and pressure.

There is no need to repair the model in the follow-up, just open the hole in the predetermined position and cut it immediately, which is about 25% lower than the cost of metal and general carbon fiber processing.

If this is not the case, it would be impossible for the TY-22 stealth drone to want 600 million yuan. At least 30% will have to be increased to reach the profit balance point.

Of course, what I said above is just an ordinary large special-shaped structure. TY-22 is positioned as a stealth drone, so in terms of manufacturing, it is better to take the factor of stealth into consideration.

Metal machining and ordinary carbon fiber composite material automatic laying machines obviously cannot accomplish this task, but China's take-off DL-535 three-dimensional braiding machine can.

Because China Ascendas uses a complex program system to control the 12846 hexagonal runners on the DL-535 three-dimensional braiding machine and 84,000 spindles that are wound with carbon fiber filaments. The hexagonal runners can do 60 degrees, 120 degrees, 180 degrees, and 240 degrees. It can rotate freely in three degrees, 300 degrees and 360 degrees, so as to control the speed and length of the surrounding yarn-carrying spindles.

In this way, under the action of 12846 hexagonal runners, 84,000 carrying spindles can weave the complex weaving method developed by China Ascendas according to the program, so that the produced composite material has extremely strong radar mirror reflection ability and internal radar scattering. And the offset effect, and finally complete the stealth effect on radar waves.

To control these 12,846 hexagonal runners and 84,000 spindles, not to mention how complicated the program is, but the computer used for intervention requires extremely strong computing power and redundancy. This is no way. China The carbon fiber weaving method studied by Tengfei requires extremely high precision, and the slightest internal error will affect the local stealth effect.

Not only that, different parts of the aircraft will also show different strong and weak reflection areas in the reflection due to the strength of the radar wave, so they need to be treated differently.

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

These differences are extremely complex calculation processes on computers. It is precisely because such a general computer is simply unable to handle such a large and complex manufacturing process. Only supercomputers with greater computing power and higher redundancy can be used. competent.

Therefore, China Ascendas ordered four Sugon-2000Ⅱ supercomputers developed by the Institute of Computer Science and Technology of the Chinese Academy of Sciences. The peak computing power reached 111.7 billion times per second.

One is set up in the aero-engine manufacturing base for aero-engine development and data test analysis.

One was used to upgrade the JSNB-IV aerospace industrial design system.

A test and data analysis for supersonic warheads and impulse combustion engines.

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

For this reason, China Ascendas Zhuan Mo spends huge sums of money to build a high-level production plant to house the huge DL-535 three-dimensional braiding machine and its supporting Suguang-2000Ⅱ supercomputer. The total investment in civil engineering alone exceeds 1.2 billion yuan, if you include the Sugon-2000Ⅱ supercomputer, DL-535 three-dimensional knitting machine and complex programming software, the total cost will exceed 10 billion yuan.

Such a large investment, such a complicated process, is only a **** in the process, if it is implemented on the product side, it can be cheap.

What's more, is 600 million yuan expensive? In the US military, only the one who is involved in stealth ~www.readwn.com~ doesn't exceed $100 million? 600 million renminbi is converted into U.S. dollars. At the current exchange rate, it is about 80 million U.S. dollars, which is the price of a top-fit ​​F-15. Is this expensive? It's a conscience, okay?

Therefore, this is also exclusively for domestic use. If it can be sold abroad, Zhuang Jianye directly exchanges the yuan after the 6 into US dollars, then it is called Mingqiu.

Of course, if the next generation of domestic combat aircraft can be mass-produced and the development of the new bomber can be successfully completed, the huge demand will naturally dilute the high production cost of the DL-535 three-dimensional braiding machine. Then it will be the real DL-535 three-dimensional braiding machine. When it was time to show off, now it's just a little trouble.

Even in some cases, it can’t catch up with the first-generation DL-520 and the second-generation DL-527 with high efficiency. After all, these two-generation three-dimensional braiding machines have been widely used by China Ascendas for satellites, missile shells, rocket engine tail nozzles, and helicopters. The production and manufacture of the main structure of the small aircraft is precisely because of the wide application, coupled with the characteristics of the three-dimensional weaving process itself that simplifies the production process, so that the high price of the kinetic energy interceptor of the anti-missile missile can be knocked down.

As a result, LYJ-18 can have a high-level kinetic energy interceptor that is no less than the world's level at a price of 8 million yuan!
