Chapter 431： Hong Kong Monster

Didn't the United States and other NATO countries call the Soviet ground effect aircraft a Caspian monster! Bao Zixuan directly named the Black Cloud version of the ground effect aircraft "Xiangjiang Monster", and he didn't know what he thought.

On the first day, all the engineers who were recruited immediately began to discuss and study the ground effect. Many people have heard the name of the Skunk Works. Since the boss built this factory with the Lockheed skunk as the target and imaginary enemy, the future work will never be easy.

Bao Zixuan also carefully considered the selection of personnel, and basically gathered the most suitable engineers and skilled workers from the entire Heiyun Group. It can be said that they are all people who can fight and win the battle.

That night, as the boss said, they were all asked to sleep in the office. Fortunately, the living conditions here are good, and the boss treated them the same. I didn't say anything, otherwise many people would really be unbearable.

After breakfast the next day, Bao Zixuan held a project meeting. Looking at everyone's eyes, it may be because the salary has increased, or it may be because you really have expectations for the project. In short, Bao Zixuan is very pleased, at least he is not worried about the current work status and enthusiasm.

With Bao Zixuan's gesture, the largest LCD screen lit up. At this time, everyone discovered that the last wall was actually made of LCD screens. The value of this equipment alone is not cheap, after all, the current LCD technology is not very mature. The processing difficulty and technical strength required for such a large LCD screen are very high, and the production cost must increase exponentially. Many components are currently only produced in the laboratory, and the yield is very low.

Bao Zixuan said while looking at the screen: "The design and planning of our first-generation Heiyun ground effect aircraft has been completed. What you need to do is to make the plan a reality, and at the same time, make improvements to the unreasonable aspects of the design."

"Black Cloud's first-generation ground-effect aircraft is named "Xiangjiang Monster", technical parameters: 108 meters long, 42 meters wingspan, 300 tons of self-weight, 800 tons of maximum take-off weight, and 50 meters of maximum flight height; the wings are equipped with 8 black Yunsan rotor turbojet engine."

The "Xiangjiang Monster" has a range of 9,000 kilometers and can transport 1,200 people around the world at a speed of 800 kilometers per hour without being detected by any radar.

After seeing the design drawings, all the engineers felt that the aircraft seemed to come from aliens. Bao Zixuan combines the aerodynamic layout of many future aircraft, making the design of Xiangjiang Monster more technological and streamlined.

The drawings combined with the data introduced by the boss made the engineer feel whether the boss really came from an alien. This product has been produced at the current technological level of the earth, and everyone is skeptical.

At this time, an engineer asked: "Boss, if the self-weight is 300 tons and the take-off weight reaches 800 tons, the material and structural strength of the aircraft may not be enough. After all, the self-weight is only 300 tons, and aluminum alloy needs to be used on a large scale, but the metal strength of aluminum alloy cannot be exceeded. High load. In this way, the entire aircraft is a contradictory existence, and we can only discard one aspect of it.”

In fact, what the engineer said is very consistent with the current situation. The vast majority of aircraft in the world use aluminum alloy welding technology.

Bao Zixuan: "We don't use aluminum alloys, but all titanium alloys; so don't worry about the mechanical strength of the metal."

At this time, another person asked: "Boss, the cost will be terrifyingly high, and there are not so many titanium alloy supplies on the market. Even if we have a good relationship with the Soviet Union, once our products come out, the Soviets may take the opportunity to cut them off. Titanium alloy supply, all our previous designs will be pushed to the beginning at that time.”

Bao Zixuan: "You can think of this very well, but we have already obtained raw materials that can replace titanium alloys in the hands of the Japanese, but the cost is still relatively high, and mass production has not yet been achieved, so the first generation products are ready to use. Titanium alloy. And it doesn’t matter if the Soviets don’t supply it, China is also a big producer of titanium ore.”

Seeing that many engineers were confused, Bao Zixuan said with a smile: "Since you are already a member of the Weasel Factory, which is the core engineer of the Black Cloud Group, there is no need to hide anything from you."

"The material I am talking about is carbon fiber material. Carbon fiber is mainly a special fiber composed of carbon elements. Its carbon content varies with different types, generally more than 90%. Carbon fiber has the characteristics of general carbon materials, such as High temperature resistance, friction resistance, electrical conductivity, thermal conductivity and corrosion resistance, etc., but different from ordinary carbon materials, its shape is significantly anisotropic, soft, and can be processed into various fabrics, showing high performance along the fiber axis. strength. Carbon fiber has a low specific gravity, so it has a high specific strength.”

"Carbon fibers are made of man-made chemical fibers with high carbon content that do not melt during heat treatment, and are made of thermally stable oxidation treatment, carbonization treatment and graphitization."

"Carbon fiber is a new material with excellent mechanical properties. Its specific gravity is less than 1/4 of that of steel. The tensile strength of carbon fiber resin composites is generally above 3500Mpa, which is 7 to 9 times that of steel. The tensile modulus of elasticity is 0Mpa is also higher than steel. Therefore, the specific strength of CFRP, that is, the ratio of the strength of the material to its density, can reach more than 2000Mpa/(g/cm3), while the specific strength of A3 steel is only about 59Mpa/(g/cm3). The amount is also higher than steel."

In the eyes of many people, these things are difficult to understand, but the people who can work in this office are all from science and engineering. The material data is very clear, and after hearing the boss's words, they all think that this material must be promising in the future.

As early as 1969, Japan Carbon Company succeeded in developing high-performance polyacrylonitrile-based carbon fibers. In 1970, Toray Corporation of Japan relied on advanced polyacrylonitrile precursor technology and exchanged carbonization technology with United Carbide Corporation of the United States to develop high-performance polyacrylonitrile-based carbon fibers.

In 1971, Toray launched high-performance polyacrylonitrile-based carbon fiber products on the market. Since then, the performance, variety and output of the products have continued to develop, and they are still in the leading position in the world. Since then, Japan's Toho, Asahi Kasei, Mitsubishi Rayon and Sumitomo Corporation have successively invested in the production of polyacrylonitrile-based carbon fibers.

Bao Zixuan obtained the patented technology and production authorization of carbon fiber material from the Japanese through patent exchange. This material has not received much attention, at least in Japan. It can be said that Bao Zixuan has picked up a leak.

There is one more thing that Bao Zixuan didn't say. Titanium alloy and carbon fiber are both luxury ground effect aircraft. In the future, the aluminum alloy version may need to be produced because of the cost, or the steel version of the ground effect aircraft may be produced because there is not so much capacity. In short, the future ground effect aircraft will have multiple versions with high, medium and low levels, and will be customized according to customer needs. It is believed that many people will choose ground effect aircraft as a means of transportation, provided that the product is sufficiently safe and mature.

Bao Zixuan: "The material problem is already a problem Then everyone has to process various parts. Our time is limited. I hope you don't waste every minute here."

Fortunately, the drawings left by the Germans are very detailed, and Bao Zixuan only slightly modified them. Otherwise, the structural layout and the trial production of parts will take a long time, and it is impossible to complete the prototype production before the Falklands War.

The data and drawings assigned to each engineer are different. Everyone knows that this is the boss's defense against them. At the same time, it also divides their labor carefully to make the work more efficient. This is normal in large equipment production, if anyone can easily see the detailed drawings. It is very difficult to keep the product secret. Competitors can easily imitate it by poaching just one person.

Looking at the detailed drawings and technical parameters, everyone felt that the money was too good to earn. After all, this is not research and development, it is more about processing parts, and it is just testing the area in charge.

Although there are detailed drawings, the engineers still have to test every part produced. After all, there is still a big difference between what is on the drawing and the real thing. The most important production of aviation equipment should not be sloppy. Any problem in any link may lead to the crash of the entire aircraft.

Don't let the company suffer losses because of your own negligence, let alone human life. If this happens, their days in the dark cloud are over. And the main reputation is also ruined. It is estimated that it is difficult to find a job in the entire industry. No aviation or shipbuilding company will use an engineer who is not responsible.
