Chapter 431: Xiangjiang Monster
Didn't the United States and other NATO countries call the Soviet Union's ground-effect aircraft a Caspian Sea monster? Bao Zixuan directly named the Black Cloud version of the ground-effect aircraft "Xiangjiang Monster," and I don't know what he thought.
On the first day, all the engineers who were pulled out immediately began to discuss and study the ground effect, and many of them had heard of the name Skunk Works. Since the boss built this plant with the goal and imaginary enemy of Lockheed Skunk, the future work will never be easy.
Bao Zixuan was also carefully considered when selecting manpower, and basically gathered the most suitable engineers and skilled workers for 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 required to sleep in the office, but fortunately, the living conditions here were good, and they saw that the boss was treated the same as them. I didn't say anything, otherwise many people really couldn't stand it.
After breakfast the next day, Bao Zixuan held a project meeting. Looking at everyone's eyes, it may be because of the salary increase, or it may be because there are really expectations for the project. In short, Bao Zixuan is very pleased, at least he is not worried about his current work status and enthusiasm.
With a gesture from Bao Zixuan, the largest LCD screen lit up. At this time, everyone realized that the wall at the back was actually made of LCD screens. The value of this set of equipment alone is not very expensive, 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 of Black Cloud ground effect aircraft has been completed, what you need to do is to make the plan a reality, and at the same time improve the unreasonable points in the design." ”
The first generation of Heiyun ground effect aircraft is named "Xiangjiang Monster", with technical parameters: length of 108 meters, wingspan of 42 meters, dead weight of 300 tons, maximum take-off weight of 800 tons, maximum flight altitude of 50 meters, wing configuration of 8 Heiyun three-rotor turbojet engines. ”
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, and will not be detected by any radar.
After seeing the blueprints, all the engineers felt as if the aircraft came from an alien planet. Bao Zixuan combines the aerodynamic layout of many future aircraft, making the design of the Xiangjiang monster more technological and streamlined.
The drawings combined with the data introduced by the boss made the engineer feel that the boss was really from an alien planet. This kind of product can be produced at the current level of technology on the earth, and everyone is skeptical.
At this time, an engineer asked: "Boss, if the weight is 300 tons and the take-off weight reaches 800 tons, the material structure strength of the aircraft may not be enough, after all, the 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 too high-loaded." In this way, the whole aircraft is a contradictory existence, and we can only discard one aspect of it. ”
In fact, what this engineer said is very in line with the current reality, and most of the world's aircraft use aluminum alloy welding process.
Bao Zixuan: "We don't use aluminum alloys, we use titanium alloys, so don't worry about the mechanical strength of the metal." ”
At this time, another person asked: "Boss, the cost will be high and scary, and there are not so many titanium alloys on the market." Even if we have a good relationship with the Soviet Union, once our product comes out, the Soviets may take the opportunity to cut off the supply of titanium alloys, and then all our previous designs will be pushed back to the past. ”
Bao Zixuan: "It's good that you can think of this, but we have already obtained raw materials that can replace titanium alloy in the hands of the Japanese, but the cost is still relatively high, and mass production has not yet been realized, so the first generation of products is 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, that is, the core engineer of the Black Cloud Group, there is no need to hide it from you." ”
"The material I'm talking about is carbon fiber material, carbon fiber is mainly a special fiber composed of carbon elements, and 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 unlike general carbon materials, its shape has significant anisotropy, softness, can be processed into various fabrics, and shows high strength along the fiber axis. Carbon fiber has a small specific gravity and therefore has a high specific strength. ”
"Carbon fiber is made of man-made chemical fibers with high carbon content and non-melting in the heat treatment process, which are made by heat-stabilized 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 steel, the tensile strength of carbon fiber resin composite materials is generally more than 3500Mpa, which is 7~9 times that of steel, and the tensile elastic modulus is 23000~43000Mpa 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), and its specific modulus is also higher than that of steel. ”
Many people think that these things are difficult to understand, but the people who can work in this office are all science and engineering majors. The material data is very clear, and after hearing what the boss said, they all think that this material must have a promising future.
As early as 1969, Nippon Carbon Corporation 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 fiber.
In 1971, Toray Corporation launched high-performance polyacrylonitrile-based carbon fiber products. Subsequently, the performance, variety, and output of the product continued to develop, and it is still in the leading position in the world. Since then, Japan's Toho, Asahi Kasei, Mitsubishi Rayon and Sumitomo have successively invested in the production of polyacrylonitrile-based carbon fiber.
Bao Zixuan obtained the patented technology and production authorization of carbon fiber materials from the Japanese through patent exchange, which has not received much attention at present, at least in Japan, it can be said that Bao Zixuan has picked up a leak.
There is another point that Bao Zixuan did not say, titanium alloy and carbon fiber are both luxury versions of ground effect aircraft. In the future, it may be necessary to produce an aluminum alloy version due to cost, or it may be due to the fact that there is not so much capacity demand to produce a steel version of the ground effect aircraft. In short, in the future, there will be multiple versions of ground effect aircraft, which 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 safe and mature enough.
Bao Zixuan: "The material problem has been solved, so we have to process various parts next, our time is limited, I hope you don't waste every minute here." ”
Fortunately, the drawings left by the Germans were very detailed, and Bao Zixuan only made slight changes. Otherwise, it would have taken a long time to prototype the layout and prototype production of parts alone, and it would have been impossible to complete the prototype production before the Falklands War.
Each engineer was assigned different data and drawings, and everyone knew that this was the boss's defense against them. At the same time, it is also a detailed division of labor for them, so that the work is more efficient. This is normal in the production of large equipment, but if anyone can easily see the detailed drawings. It is very difficult to keep the product secret, and competitors can easily copy it by poaching a random person.
Looking at the detailed drawings and technical parameters, everyone feels that this money is not too easy to make. After all, this is not 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 inspect each 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 can not be sloppy, any link problems, may lead to the entire aircraft crash.
You must not let the company suffer losses because of your own negligence, let alone kill people. If this is the case, their days in the dark clouds will be over. And the main reputation has also been ruined, it is estimated that it is difficult to find a job in the entire industry, and no aviation and shipbuilding company will use an engineer who has no sense of responsibility.
