Take Off My Aviation Era

, The fastest update to take off the latest chapter of my aviation era!

Medical gas turbine, another name called dental gas turbine handpiece, is an advanced dental medical device.

As the old saying goes, toothache is not a disease, but it is really terrible when it hurts. Therefore, dentistry is a very important medical classification in various countries, and many dental treatments often require the enamel and dentin shells to be drilled away. In order to expose the dental pulp or necrotic tissue where the lesion has occurred, it is convenient for its resection or drug treatment.

On the contrary, teeth are the hardest part of the human body. Traditional methods simply cannot achieve the purpose of drilling and grinding teeth. Therefore, medical equipment specially used for tooth drilling and grinding came into being.

In the early stage, it was purely mechanical. The doctor used the pedals with his feet to treat the patients with the turned head. As the speed was only a pitiful more than a thousand revolutions and the efficiency was slow, the patient was also extremely painful during the treatment. .

Later, with the advent of motors, the traditional mechanical drill bit was replaced by a miniature electric drill bit, and the rotation speed increased from the original several thousand revolutions to tens of thousands of revolutions.

However, due to the inherent shortcomings of the motor, the lubrication and water spray cooling devices cannot be inherited to the drill bit, and the dentist is often in a hurry during treatment.

Because of this, Western countries developed a new type of tooth drilling and grinding equipment in the late 1950s. That is a gas turbine. The principle is very simple. It uses compressed air to drive a micro turbine to rotate, so as to obtain 300,000 per minute. Turn above the high speed.

At the same time, because of its pure mechanical mechanism, it is easy to integrate a water spray cooling device inside, so that while drilling and grinding the teeth, it is possible to cool and clean the patient's mouth with water, thereby reducing the patient's pain.

The principle is very simple, but it is very difficult to make it. Everything else is easy to handle. The difficulty lies in the micro-turbine called the movement inside.

Not only does it need to be small and exquisite, but the weight is strictly limited within a certain range. That’s all. The point is that the centrifugal force generated by hundreds of thousands of revolutions per minute is quite terrifying. It is possible that ordinary materials have not reached the target. Torn to pieces by strong centrifugal force.

In addition, processing accuracy, overall airtightness, and special testing equipment are all very demanding, causing ordinary companies to want to do it, but can't do it.

Because of this, gas turbines have been monopolized by a few western companies once they came out. Not to mention the blanks in China, most medical device factories have never even heard of it.

It's just that this kind of high-performance turbine core is a dreadful step for domestic medical device manufacturers, and it is very difficult even for some ordinary precision manufacturing plants, but it is not a problem for Ascendas.

No matter how complicated this kind of turbine is, is it complicated by the turbine in a jet engine?

Not only has to withstand high temperatures, but also withstand high pressure. As for centrifugal force, each square centimeter has to withstand nearly five tons of tearing. The turbine in the gas turbine is just ordinary compressed air, and the working environment is simply not too good.

As for the materials, parameters, and transmission, they are more than one level lower than the aero-engine, otherwise the aero-engine would not be called the jewel of the industrial crown.

There are technology, materials, talents, and equipment. In addition, in order to save money in the past two years, Master Ju and others have been using clock processing equipment to do theoretical feasibility studies on miniature testing machines with a diameter of 10 to 20 cm. , So that the factory has the ability to process micro-components.

Everything is in place, and only one product is needed to integrate it into realization. Zhuang Jianye, who had been tortured by toothaches in his previous life, will make high-end medical equipment. Not only high-end medical equipment, but also huge profits.

The key is that the barriers to entry are high. Once a word-of-mouth effect is formed, it is easy to form a monopoly, not to mention cramps when counting money, and the company is still not leaking, which is in line with the corporate philosophy of Ascendas plant to make a fortune with a low profile.

As for the so-called leafless fan, TM is a pit. It may make a small fortune at the beginning. The problem is the harsh domestic intellectual property environment. Within two years, this thing will have to be blossomed everywhere.

The best thing for Ascendas is to split the market equally with a few giants. If you make a little mistake, you may become the poor VCD inventor and shut down hastily.

The jet engine office is a long-term job. Earning quick money can only solve a temporary need. Compared with the entire jet engine research and development, it is better to find a long-term, stable and profitable business.

Gas turbines are very good. Companies like the 517 factory want to do it but can’t do it. The large aviation development factories in this system have the technology but don’t like this kind of pediatrics. Such a huge market is so empty. Zhuang Jianye is sorry if he doesn’t pick it up. Own conscience.

Therefore, Zhuang Jianye is very generous to disclose all the bladeless fans can be made public. It is a gimmick. It attracts people's attention and pays attention to it. Its mission is completed, and the gas turbine is the real flagship.

Because he believes that at this trade fair jointly organized by several ministries and commissions, the leaders of the health system, like those in charge of other systems, will inevitably participate, even if there is no medical equipment they want to participate in the exhibition, but for the higher level to call for support In the arduous development of the national defense and military industry, how can the health system also spend some pockets to buy some TV sets, refrigerators, electric fans, duvet covers, bed sheets, etc.

What if there is suddenly a medical device among these inconsistent light industrial products that the medical system needs to import in large quantities every year?

Obviously, the effect is surprisingly good.

I saw that the old man who exclaimed put the gas turbine in his hand and took a look to the left, then looked at ~www.wuxiaspot.com~ that’s not a big deal, and asked Zhuang Jianye and Master Ju to switch on the equipment and give it a try. Then a serious smile finally appeared on his serious face: "Well... Judging from the feel, it is not inferior to foreign products."

At this time, Zhuang Jianye had known the identity of the old man from the cadres of the aviation system. He was indeed the leader of the health system. His name was Hong Xiaosong. Last year, he was transferred to the head of the health department from Beijing Union Hospital.

Not only is a square person, but he also has excellent medical skills, especially in otolaryngology, and he is one of the countless experts in China. Therefore, this Hong Xiaosong is no stranger to dentistry and is even more proficient than ordinary experts.

After learning about the situation, Zhuang Jianye immediately confessed to Master Ju. Soon Master Ju brought two hard-boiled eggs. Zhuang Jianye quickly received it and walked to Hong Xiaosong who was taking a closer look at the gas turbine, laughing. He said: "Dr. Hong, I heard that foreign skilled doctors can engrave on eggs. You are also an expert in this field. Can you also mention one on the eggs."

He handed over two boiled eggs as if offering treasures.

Originally, Hong Xiaosong was very happy to see the domestic medical equipment here. He couldn't bear to put it down when he got it. Now, when he heard this, he scratched his itchy spot, and nodded without thinking: "Okay!"
