Chapter 730 An inconspicuous technology comparable to aero-engines

Next is the parts production functional area. This area is the largest and the most complicated. Basically all the important parts of the products are produced here.Because there are so many, the old people have to choose to visit some.Contrary to Jiang Chen's expectations, the first thing the experts wanted to visit was not the core engine production plant or other core technology plants, but the tire production plant.Seeing Jiang Chen was puzzled, the old people smiled and explained to Jiang Chen.That is, don't underestimate this aircraft tire. Now there are basically no manufacturers that can produce it in the whole country.In the Yun_10 project, the old people have suffered a lot from this small and neglected component.Some leaders even got mad about this, saying that we can even make airplanes, why can't we make this small airplane tires.

Let's put it this way, the technical difficulty of this aircraft tire can even be compared to the engine technology of this aircraft. Our country only announced that it has mastered this technology in the next year or five years.Aircraft tires, also known as aviation tires, are one of the important components on aircraft with high safety and reliability requirements, and need to withstand high speed, high load, and high internal pressure.It plays an extremely important role in the safe take-off, landing and taxiing of the aircraft, and the conditions of use are very harsh.High internal pressure requires the tire to have more layers of skeleton materials, and the carcass of aircraft tires is thicker, which generates more heat.High internal pressure will increase the ground pressure of the tire. The airstrip stipulates the maximum ground pressure. Therefore, the tire increases the ground contact area by increasing the sinking rate to meet the requirements of high load and low pressure.However, the higher the sinking rate, the greater the deformation of the tire and the greater the heat generation, which requires the tire to have good heat resistance and thermal conductivity.Simply put, the performance characteristics of aircraft tires include high load capacity, high inflation internal pressure, high heat generation, high speed, and short continuous gliding distance.

These characteristics require that the tire must adopt special materials and technology, and the structural materials of the materials used not only have particularly high physical properties, low heat generation, but also reasonable configuration.Moreover, when developing and producing aircraft tires, it is necessary not only to consider many factors such as wear resistance and anti-aging characteristics of ordinary tires, but also to choose and use more stringent rubber raw materials for its special working environment.Because of the high technical difficulty, which is not conducive to R&D and production, our country's aviation tires have long relied on foreign supplies, especially for more demanding military aviation tires.After the joint efforts of several generations, it finally got rid of the dependence on foreign products in the next year or five.You must know that we announced the successful development of aero-engines much earlier than this time, so we can see the difficulty of this aircraft tire technology.

After hearing the old man's explanation and Jiang Chen's memories, Jiang Chen suddenly realized why he had forgotten this seemingly inconspicuous matter, thanks to the old people reminding him in time.After hearing the introduction of the old people, the leaders and researchers of the tire factory were also very moved. They did not expect that such a small tire would have so many requirements and such a high difficulty.This immediately aroused their fighting spirit, and someone assured Jiang Chen that they would definitely be able to research and produce this aircraft forum.Jiang Chen was very pleased about this, and the old people were also very happy, and told them that the technical information on aircraft tires is now in the newly built data storage center, and they can go there to check it out, and they can come and ask any questions they have. them.ask them?This made the factory leaders and technicians very confused. After hearing Jiang Chen's introduction and explanation, the factory leaders and technicians became excited.This is to build an airplane, and everyone is gearing up to do a big job.Because the better the company develops, the higher the benefits of their factories will be, and their wages will also increase accordingly. How can they be unhappy.

Then everyone came to the factory where the car chassis frame and skin were stamped.Coming here, these old people can't wait to see the specific situation of this.You know, the skeleton and the skin are two important parts of the aircraft, and they are also two important technical difficulties.The first is the skeleton structure, which requires high strength and good toughness, and is able to adapt to the effects of extreme environments such as high or low temperature, high humidity, and dryness on these skeletons.For example, what we often say about thermal expansion and cold contraction is extremely demanding on airplanes.What to do when the material expands, and what measures to take when it shrinks, these are issues that engineers have to consider.And there is another important requirement, that is, it must be light. While requiring strength and toughness, its weight must be taken into account.If the weight is too heavy, it is not suitable, because too heavy weight will affect the take-off weight of the aircraft, increase the fuel consumption of the aircraft, reduce the passenger or cargo capacity, and affect the flight range, and even the requirements for the take-off runway. influential.So don't look at just the skeleton structure, the required technology is extremely complex, and the difficulty is very high.

Next is the pressing workshop of automobile panels. The old people are very interested in this and watched the whole production project carefully.However, the old people are not satisfied with the result, because the pressure used for pressing the automobile plate is too small, and it is only used for the pressing of the automobile plate. Like the components and plates on the large aircraft, such pressure and strength are far away. not enough.Although Jiang Chen said that they are currently only producing ****, but they frequently provoke the old people to stare at each other.In their words, you've been building airplanes instead of big airplanes, so what's the point of asking them to come.In this regard, Jiang Chen can only admit his mistakes again and again, and assure the old people that the medium-sized and large-scale hydraulic machines will be established as soon as possible, and put into this research and construction, and will not affect the development and use of the old people. Let the old people smile again.

Next is the engine production plant. The old people don't seem to have much enthusiasm for it. In their view, these are children's science, compared to aircraft.However, they seem to be very interested in this new type of material and high-precision gears and other parts, because in their opinion, this kind of high-precision parts processing and manufacturing is widely used in aircraft, so they need it very much.If it wasn't for Jiang Chen's obstruction, it is estimated that the director of production technology of this factory would be dragged by the old people to build airplanes.

In addition, the old people are also very interested in this electronic component research and development laboratory, especially after seeing a lot of modern tiny electronic components and micro-miniature integrated circuits, which made them very interested, and they all affirmed it .This was also the only place where the old people collectively praised Jiang Chen all day long.Everyone thinks that Jiang Chen has done a good job in this project. This kind of miniature electronic components and micro-miniature integrated circuits use a lot of space for both civilian and military applications, and they can also be used very well on aircraft. use.Even a few experts who specialize in the research of flight control fly-by-wire on aircraft stayed away, saying that they wanted to continue their research here and strive to design and develop a more advanced control fly-by-wire system.
