C1140 The Process must be Improved

3In the engine, the leaves play a vital role. Moreover, in the process of working, the leaf had to be affected by centrifugal force, air power, thermal stress, interchangeability, random load, and so on and so forth. Under the effect of all kinds of load, the leaf could easily cause high periodic fatigue, heat fatigue, and low periodic fatigue to be damaged.2

If the leaf did not meet the requirements, it would spray parts continuously after it got on the platform. The next piece of the leaf would fly out at a high speed, which was enough to cause an accident.

Such a scene had happened countless times in the development of engines in Han Country in the future.

Now, even with the successful research and development of the Spey, it couldn't guarantee the development of the new generation of engines.

The leaves were made of aluminum alloy, stainless steel, titanium alloy, high-temperature alloy, Compound Materials leaf, and so on. The specific materials had to take into consideration the working temperature, strength, state, and weight.

Comparatively, economics was the last thing to consider. In the past, the Turbojet Engine in Han Country used stainless steel or aluminum alloy pressure leaf, but now, it had already started using titanium alloy.

Titanium alloy, because of its low weight, high intensity, and resistance to corrosion. Its contribution in weight reduction was outstanding, so it was used in large numbers in the aerospace field. Take the current J-11 Fighter for example, the usage of the titanium alloy on it had greatly increased.

Apart from using materials, the design and processing process were also very different.

The early stage of the fan leaf was limited by the manufacturing technology. It was a solid, narrow chord, and a convex structure. Along with the development of the manufacturing technology, in order to increase the efficiency of the fan leaf, to reduce the weight of the fans, a wide chord, or hollow structure was used to replace the solid structure. The Spey's engine leaf was solid, and was only used to craft. The new third-generation console's Core Fighter should be made of hollow titanium alloy. Unfortunately, due to the lack of processing technology and the consideration of cost, this resulted in Elder Wu still using the leaf processing technology on the Spey.

The processing process did not change, but the design of the leaf had also changed. This naturally did not meet the requirements.

The titanium alloy had an extremely high yield strength at normal temperatures, and its plasticity was very poor. Moreover, it was easy to produce a rebound. It was difficult to guarantee the accuracy of most of the engine leaves formed by conventional metal processes. Moreover, it took a lot of time and effort to ensure its performance.

This called for the arrival of a new technique. The Super Plastic Forming / Diffusion Welder welding technique was a combination processing technique that was developed by utilizing the material's good solid-state solid-adhesion performance in the super plasticity state.

This process could use the excellent super plasticity and diffusion connectivity of titanium alloy to create multiple layers of titanium alloy components. The cost and weight would be reduced by 30% to 50%. It could save time. Conserve time. The raw materials could increase efficiency, and the components could be processed with light weight and good structural integrity.

Super plasticity usually referred to the fact that under certain conditions, the material would display an abnormally high extension rate without causing neck contraction or breakage. When the extension rate was higher than 100%, it could be called super plasticity.

The diffusion connection was to compress two or more solid materials together, placing them in a vacuum or protecting the atmosphere and heating them to the temperature below the melting point of the mother material. Exerting pressure on them would cause the microscopic deformation of the concave area of the connection interface to reach a close contact. Then, through thermal insulation and the diffusion of the atom, it would form a firm metallurgy link.

Why could the Spey be exported to Han Country? Because the Spey was the engine of the previous generation of people in Cattle Country, and the weight ratio was only 5. Since it was already lagging behind, of course it could be exported to make money.

But how could these most advanced and newly developed techniques be given to Han Country?

"If we want to achieve this kind of newest technology, then we need to expand the connection - Super Sculpting Equipment. Spread the connection to the heating equipment, spread the connection - Super Plastic Forming Vacuum Extraction Equipment. As long as I have these equipment, I will be able to operate them. " Robert said.

He also knew the difficulty of this. It would be great if Han Country imported these equipment from overseas.

"At the same time, the temperature of the titanium alloy is 850 ~ 980 degrees Celsius. The temperature of the diffused connection is 870 ~ 1280 degrees Celsius. Due to the temperature of the superplastic, the diffused welding conditions are met. Moreover, both of them need to be carried out in a vacuum or protected gases, so they can combine the two processes. In a heating and pressurizing process, the super molding and diffused connection were completed. I have long thought of doing this. It is a pity that the Rolo Company's brick masters are afraid of producing defective products. I didn't adopt it."

This was not something that could be settled by Cnc Machine Tool. It was an advanced Cnc Machine Tool. It's just to increase the precision of processing. The manufacturing of titanium alloy leaves. It required an updating process. It was not produced by a car. Instead, it was directly formed by super molding and then spread out and welded.

Qin Guan nodded and suddenly thought of something. It was very simple. How did the leaf of the F404 engine be processed? Could it also be the same process?

Especially if the production line of the engine was also in charge of the production of the leaf?

There were countless parts to the fighter aircraft, and the production line was just the general assembly line. However, the engine was definitely not like this. After all, the engine was a high-tech product. Maybe I'll buy an accessory or something. But the main body of the engine... It must have been produced on a production line. If the leaves of the engine were to be produced by other factories... Could it still produce engines?

Qin Guan made up his mind and said, "We must use a new technology to surpass this third-generation machine. Since we are required to use this leaf, let's make it. As for the relevant equipment, we, the North Industrial Company, will think of a way. "

Elder Wu was instantly delighted. Since Qin Guan said that he would find a way, he would definitely be able to find a way. If he could create this leaf, then the Core Fighter on the engine would be tested again, and there wouldn't be any problems.

As for now, there was no way to test the engine. They had to wait for the arrival of a new process.

"President Qin, this kind of engine uses titanium alloy in large quantities. I'm afraid the price will increase." Elder Wu continued.

"No matter how high the price is, it is still lower than us buying the engine, right? Besides, this way, we'll be able to control our own destiny. We won't be stuck on the trigger again. Elder Wu, let's talk about it in detail. Besides the most critical thrust engine right now, we also have a strong need for a medium thrust engine. "

Elder Wu took off his glasses and rubbed his eyes. "Yeah, we still have a need for a medium thrust. President Qin, but we can't be too busy."
