Take Off My Aviation Era

"Take off my aviation era ( to find the latest chapter!

In fact it is true.

The KDP crystals pioneered by the Americans, so the Soviets during the Cold War dared not care. If they were used to imitate them, they would imitate them. If they were used in sensitive fields, they would use them in sensitive fields. Not only did Americans dare not fart, they had to pinch their noses. Use it well.

There is one of the remaining other countries that dare to be so arrogant? The same is true in China. KDP crystal Americans are open to the world in the field of research, but they are very determined in the field of application. Whoever wants to cross the red line, even if it does not kill you in the field of optics, it will not make you want to be immoral in other aspects. dead.

This is the all-round hegemony supported by the super comprehensive national strength.

Therefore, Ascendas Group can use KDP crystals to produce solid-state lasers, but the treatment is not as good as that of Japan and South Korea. Not only does it have to pay twice the patent fee, but the KDP crystal solid-state lasers produced can only be used for cutting general steel and general aluminum alloys. .

Yes, that’s right, paying the IQ tax will not allow you to use it properly, confining you to general steel and general aluminum alloy.

Ascendas Group is an aerospace and aerospace manufacturing company, not a workshop for processing aluminum alloy doors and windows and iron fences in the compound. Such conditions in the United States are indeed a challenge to Ascendas Group’s collective intelligence.

The price is high and there are conditions. The most important thing is that he actually insulted IQ. Five years ago, he wanted to take a shortcut and was shameless to kneel down for related American technology companies. Finally, he couldn't kneel down because he didn't want to kneel down. It’s not that the lives of tens of thousands of people in the Ascendas Group, including himself, will be cut away by the Americans.

So Zhuang Jianye stood up slowly with his arms supported, then dusted the dirt on his knees, turned his head and said to his partner: "Don't let the shortcut go, let's do it ourselves."

As a result, this work led to a world leader.

Yes, it is truly the world's first, otherwise Zhuang Jianye would not be able to say that his Ascendas Group is a leader in the global laser field, this is not bragging, but a fact.

Needless to say, the NB-6600DL ultra-precision laser hole-making machine that has amazed Aziz and others, in addition to using the LBO crystal, which is different from the US KDP crystal, and Ascendas Group has completely independent intellectual property rights as the main material of the solid-state laser, The processing technology is also not subject to foreign constraints.

Because Ascendas Group uses femtosecond laser processing technology instead of traditional pulsed laser.

This is why Ascendas Group can replace the original electrochemical hole-making equipment with NB-6600DL ultra-precision laser hole making, which has become the key equipment for Ascendas Group's new generation of flame tube and turbine blade film cooling hole processing.

The key to the core is that Ascendas Group has mastered femtosecond laser processing technology.

Although both belong to laser, femtosecond laser is different from pulsed laser. It has the characteristics of short time and high energy density. Because of this, the energy of femtosecond laser acting on components is not the thermal energy of pulsed laser, but a similar Coulomb repulsion of ionization.

This is because when this femtosecond laser interacts with materials, it removes the excitation of free electrons in the material, and relies on the Coulomb repulsion between the positively charged material molecules to remove the material, thereby eliminating heat generation under this mechanism.

At the same time, because the peak power of the femtosecond laser can reach the order of 10 megawatts, and the electric field intensity is extremely high, much larger than the Coulomb field in the atom, it is enough to ionize any material, and realize the material in the working area is plasma The form is removed.

Based on this, the femtosecond laser can perform micro-precision cold processing such as hole making, micron-level etching, and cutting on any material, and it will not produce thermal stress, recast layer, micro-cracks and other phenomena on the processed parts, which is enough to bear the gas of turbine blades. Machining of film cooling holes and flame tube precision cooling holes.

From the thermal processing of pulsed lasers to the removal of plasma from femtosecond lasers, Ascendas not only breaks the monopoly on solid-state lasers, but also leads the world in processing technology.

We must know that the precision machining of film cooling holes in the world today is still dominated by electrochemical machining equipment.

The process cannot be said to be excellent. The problem is that the efficiency of electrochemical machining is really not flattering. Not only that, the configuration of the electrochemical solution is also different for different materials and different compositions.

As a result, the cost of one milliliter of electrochemical solution is almost as fast as one gram of gold.

That's all, anyway, the value of the aero engine itself is much more expensive than the same weight of gold. The problem is that the failure rate of electrochemical machining is too high.

No way, the chemical fluid guide tube on the electrochemical processing equipment is easily corroded by the internal chemical fluid, so it needs to be replaced frequently. In addition, the equipment coordinating organization must also real-time teamwork, otherwise the chemical fluid injection will be fast or slow This will affect the processing accuracy of the material.

If you are negligent, the whole device will be shown to you.

It’s okay if other equipment is repaired. Anyway, it’s all mechanical, and it’s not a big deal if it’s disassembled or disassembled. The problem is that there is still this chemical liquid in the electrochemical hole-making equipment. This is not only expensive, but some types are also poisonous.

So this thing is laborious to produce, and it can drive people crazy when they are repaired.

How other aviation manufacturing companies are not clear, anyway, Ascendas Group was tortured by this thing a few years ago, it was almost crazy, but no matter how crazy, it had to endure it at that time, because in addition to electrochemical precision hole processing equipment can be used at room temperature No other equipment can replace the film cooling holes of the turbine blades.

The key to the second-generation core engine of Ascendas Group is the film cooling holes of the turbine blades.

So no matter how troublesome it is, no matter how high the failure rate is, Tengfei Group has to recognize it while holding its nose.

But now, Ascendas Group has mastered the solid-state laser, and has overcome the femtosecond laser processing technology. In the past, it has become much simpler to process the gas film cooling holes that were painful up and down on the production side.

There is no need to redistribute the chemical liquid according to the material, no need to adjust the hose and speed, let alone worry about the toxicity and possible failure of the chemical liquid.

The same is normal temperature, the same is cold processing, and the same is one-time molding.

The NB-6600DL ultra-precision laser hole making machine is just like an ordinary CNC machine tool. The parts are placed on the worktable and the CNC program is input. The laser will punch out the micro-precision holes one by one with a femtosecond laser.

If it is necessary to say that the NB-6600DL ultra-precision laser hole making machine is somewhat different from other precision hole processing equipment, it is that the environmental requirements of the workshop are extremely high, almost meeting the environmental requirements of semiconductor production.

There is no way, who makes the NB-6600DL ultra-precision laser hole making machine full of precision optical components, even the slightest pollution will affect the processing accuracy, so the investment in the construction of the workshop is very considerable~www.readwn.com ~But even so, the efficiency and accuracy of the NB-6600DL ultra-precision laser hole making machine are there. Even if the huge investment in the workshop is included, the overall cost is still one-third less than that of electrochemical hole making equipment.

Because of this, as soon as Ascendas Group mass-produced the NB-6600DL ultra-precision laser hole making machine, the engine manufacturer put all the NB-66 type electrochemical hole making equipment on its hands into the cold palace and completed the leapfrog upgrade.

However, many of the electrochemical hole-making equipment are in good condition. It is a pity to just leave them in the warehouse and eat ashes. So after Zhuang Jianye talked with Aziz and others about the process of laser hole making, Zhuang Jianye changed the subject: "We The cooperation between Ascendas Group and the two countries is very sincere. I am also a real person. I have always been a gentleman before a villain. The NB-6600DL ultra-precision laser hole making machine is an advanced equipment that our country prohibits export. Mr. Chitz, you are here also specially approved by the head of our headquarters, in order to show our sincerity in cooperation.

But as far as I am concerned, just looking at something is not considered sincere. Just as I said in Pakistan with His Royal Highnesses Abdullah and Mahmoud, since cooperation must be mutually beneficial and win-win, you invest money, we Naturally, good technology and good craftsmanship must be produced. This is called sincerity, right?

Therefore, the NB-6600DL ultra-precision laser hole making machine cannot be sold. I can always provide partners with other advanced equipment and technologies. I applied to the head of the headquarters and tried to persuade him for three days before letting him relax and allow us to take off. The group sold NB-66 electrochemical hole making equipment to the two countries. The original unit price of 200 million U.S. dollars was half of the price to show its sincerity. "

"Really?" Aziz heard the words, and a pair of old eyes opened immediately.
