Chapter 1351: Bring down the price

Previous page        Return to Catalog        Next page

    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 desire to take off.

    Of course, these arbitrary prices are basically external in accordance with China Tengfei's past rules, and internally they are still based on the legal framework and basic code of conduct within the cabinet. Because of this, the ty-22 stealth drone is sold for 600 million yuan.  Although the price is high, it really doesn't cost a penny more.

    Not to mention anything else, the ty-22 stealth drone is focused on the streamlined and rounded wing-body fusion structure that wraps the engine.

    Four cabin openings need to be left for inspection and maintenance of related equipment. The rest must be completely integrated with the flying wing layout fuselage without any traces of connection or exposure. Only in this way can the basic aerodynamic layout structure be guaranteed.  and stealth performance.

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

    Let alone the three-dimensional knitting machine used for second-generation composite materials, even with the most traditional metal materials, it is not easy to make large-scale special-shaped structural parts that are integrated with the wing body of the flying wing.

    Not only does it require precision forging, but it also requires at least seven-axis and five-link high-precision machine tools for detailed machining to complete.

    This does not include the heat treatment, flaw detection and compensation processing and other detailed work in the manufacturing process. Not counting the materials, the cost of processing is already outrageously high.

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

    What¡¯s more, the subsequent curing in a high-temperature thermal furnace also costs a lot of money. The precision cutting and shaping after curing also require precision professional machine tools to complete. The total cost is only higher than that of machining.

    It is different to use the dl-535 three-dimensional knitting machine developed by China Tengfei to manufacture such large special-shaped structural parts, because the dl-535 three-dimensional knitting machine uses the basic principles of the textile industry to produce a highly precise prefabricated part.  After that, only a basic mold is needed, and the epoxy resin is cured under a certain temperature and pressure.

    There is no need to modify the shape later, you only need to make holes at the predetermined position, and the cutting is instant. The cost is about 25% lower than that of metal and general carbon fiber processing.

    If this were not the case, it would be impossible for the TY-22 stealth drone to cost 600 million yuan. At the very least, it would have to increase by 30% to reach the profit balance point.

    Of course, the above mentioned are just ordinary large-scale special-shaped structures. The ty-22 is positioned as a stealth drone, so the stealth factor must be taken into consideration in manufacturing.

    Metal machining and automatic laying machines for ordinary carbon fiber composite materials are obviously unable to complete this task, but China Tengfei¡¯s dl-535 three-dimensional braiding machine can.

    Because China Tengfei uses a complex program system to control the cooperation of 12,846 hexagonal runners and 84,000 yarn-carrying spindles wrapped with carbon fiber filaments on the dl-535 three-dimensional knitting machine. Among them, the hexagonal runners can do 60 degrees, 120 degrees, 180 degrees, and 240 degrees.  Free rotation of 300 degrees, 360 degrees and 360 degrees to control the speed and length of the surrounding yarn-carrying spindles.

    In this way, under the action of 12,846 hexagonal wheels, 84,000 yarn-carrying spindles can weave the complex weaving method developed by China Tengfei according to the program, so that the composite materials produced have extremely strong radar specular reflection capabilities and internal radar scattering  and offset effects, ultimately achieving the stealth effect against radar waves.

    If you want to control these 12,846 hexagonal wheels and 84,000 yarn-carrying spindles, not to mention how complicated the program is, but the computers used for intervention require extremely strong computing power and redundancy. There is no way, China  The carbon fiber weaving method researched by Tengfei requires extremely high precision. The slightest internal error will affect the local stealth effect.

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

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

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

    So China Tengfei ordered four Suguang-20002 supercomputers developed by the Institute of Computer Science, Chinese Academy of Sciences, with a peak computing power of 111.7 billion times per second.

    ?????????????????????????????????????????????????????????????????????????????????????????????????????????????? ??Aero engine development and data test analysis.

    ?One unit is used to upgrade the jsnb-4 aerospace industry design system.

    ???A test and data analysis used in hypersonic warheads and flush combustion engines.

    The last one is equipped with a dl-535 three-dimensional knitting machine, which is used for the production and manufacturing of specialized stealth composite materials.

    To this end, China Tengfei Zhuanmei spent huge sums of money to build a high-level production plant to house the huge DL-535 three-dimensional knitting machine and its supporting Shuguang-20002 supercomputer. The total investment in civil construction alone exceeded  1.2 billion yuan. If you include the Shuguang-20002 supercomputer, dl-535 three-dimensional knitting machine and complex programming software, the total cost exceeds 10 billion yuan.

    With such a large investment and such complexity, it¡¯s only a matter of fact that the process and implementation on the product side can be cheap.

    Not to mention, is 600 million yuan expensive?  As long as the US military has something to do with stealth, which one has less than $100 million?  600 million yuan is converted into US dollars. According to today's exchange rate, it is about 80 million US dollars, which is the price of a top-end F-15. Is this expensive?  It's really a good conscience, okay?

    So this is exclusively for domestic use. If it can be sold abroad, Zhuang Jianye will directly convert the RMB after 6 into US dollars, which is called Mingqiang.

    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 the dl-535 three-dimensional knitting machine, and then the real value of the dl-535 three-dimensional knitting machine will be  When he showed off his skills, now it¡¯s just a small fight.

    At some points, it is not even as efficient as the first-generation DL-520 and the second-generation DL-527. After all, these two generations of three-dimensional knitting machines have been widely used by China Tengfei for satellites, missile casings, rocket engine tail nozzles, and helicopters.  And the production and manufacturing of the main structure of small aircraft. It is precisely because of its wide application, coupled with the characteristics of the three-dimensional weaving process itself that simplifies the production process, that the price of the high anti-missile missile kinetic energy interceptor has been brought down.

    This enables lyj-18 to have a high-level kinetic energy interceptor that is no less than world-class at a price of 8 million yuan!
