China's helicopter industry, in 2011, is still a bit out of step with the advanced.

It will not until the next few years that it will gradually break out, and it will slowly catch up.

Whether it is the engine or blades, or some other key parts, in fact, there are still some gaps with the advanced level of foreign countries.

Although Cao Yang didn't know why the other party didn't develop the engine by himself, he was discussing the main reducer.

However, this is also a very core difficult part.

Most of the components of the final drive of modern helicopters, including gears, shafts and receivers, are designed for an infinite life, but in fact they are used for a limited life.

Therefore, it is required to remove the final reducer from the helicopter and send it to the factory for renovation after every period of work in actual use; Replace the worn parts, inspect them and then put them on the helicopter and put them back into service.

It can be said that this is the typical design without problems, but the production of problematic parts.

Obviously, the products produced by the manufacturers of the final reducer are very dissatisfied with the life of the relevant departments.

That's why I found Nanshan Group to try to find a better production plan.

"The integrated shaft-bearing-gear design of this final drive should be very effective in reducing weight and cost, and improving reliability."

"But this places very high demands not only on raw materials, but also on machining precision."

"And the final heat treatment also needs to balance the special needs of different parts."

"It's a bit difficult to really have an infinite lifespan."

Cao Yang is not an entrepreneur who only knows how to eat, drink and have fun.

As the core technical expert of Nanshan Group, he saw the drawings and related requirements given by the other party, and he had some judgments in his heart.

Next to him, Ji Hua, Dai Hanbiao, Xie Lingyun and others also carefully studied the design drawings given by the other party.

"That's true, but this design scheme is the most advanced design scheme in the world, as long as it is successfully produced, there is no need to worry about it being outdated for more than ten years."

"And as helicopter technology continues to evolve, the power required from the final drive is increasing, and the load at the gear meshing is also surprisingly large."

"A helicopter main reducer with a transmission power of 3,000kW, in which there is a pair of meshing gears to withstand a force of up to 10,000kg, in order to ensure the strength of the gears and shafts, the reducer has to pay a considerable weight price."

"For example, the weight of the helicopter's final drive generally accounts for 15% of the weight of the entire helicopter structure."

"This is very difficult to accept, so the integrated design of shaft-bearing-gear is adopted to reduce the weight as much as possible."

"However, objectively, it does increase the difficulty of parts processing."

The technicians who came with Pan Jun did not deny Cao Yang's statement at all.

After all, these things that Cao Yang said, they have been studying for several years.

It's almost time to produce it.

"Mr. Cao, if it is a small batch to produce this kind of final reducer, our existing equipment should also be able to meet the requirements."

"But if you want large-scale production, it is best that Nanshan equipment can specially customize and produce a large-scale high-precision CNC five-axis machine tool."

"Then Nanshan Special Steel also needs to consider some optimization of our existing bearing steel and gear steel formula."

As a gearbox expert, Ji Hua still feels more kind when he sees this final reducer.

After all, the reducer and gearbox are essentially the same type of parts.

He just looked at the drawings and had an idea of the relevant requirements.

"The special steel used in our high-speed rail bearings and axles should be able to meet this design requirement after appropriate formula adjustments."

"As for the final surface treatment, you can try it a little more."

After studying the drawings, Dai Hanbiao also gave his own opinions.

Pan Jun brought people over to ask for help, and Cao Yang had the intention of personally participating in it, so they senior technicians naturally couldn't drop the chain.

"Mr. Cao, if you want to produce a few prototypes, how long will it take you?"

The other party looked at Cao Yang with expectant eyes.

Although he was full of expectations for the Nanshan Group when he came, he was still relieved to hear the relatively accurate exchange information now.

"If it's just a simple machining of parts, then a maximum of 3 months is enough."

"However, if you want to continuously debug and select the most suitable material formulation and heat treatment solution, it is estimated that it will take six months."

Cao Yang thought for a moment and gave his own reply.

Small-scale production requires little or no permanent tooling, and most of these parts are machined and heat treated after forging a profile.

If it goes well, it is possible to make some samples in a month.

Of course, considering that the structure of the helicopter's main reducer is still relatively complex, the workload of various machining alone will not be small.

In addition, some heat treatment requires a fixed time, which cannot be fast.

So Cao Yang reported a relatively conservative time.

But this has already made the other party very satisfied.

As long as Nanshan Group is confident that it can be done, let alone 6 months, it can be accepted in a year.

After all, it's not that they don't have parts now, but they are not satisfied with the life of the parts now.

The cost of a reducer is not low, and the low life means that the cost of using the helicopter will be relatively high.

This is certainly not good for large-scale equipment of this helicopter.

Soon, the two sides began to sign some non-disclosure agreements, and then the other party delivered more detailed drawings and 3D data to Nanshan Group.

Cao Yang began to arrange for people to try out.

……

"Mr. Cao, the relevant departments even asked us to produce the helicopter main reducer, which shows that the technical level of domestic helicopters is really not particularly high."

"I briefly studied the engine, the rotor system and the transmission system, which are the three core parts of the helicopter, and the engine we can try to challenge."

"And with the final drive in place, the drivetrain isn't a problem for us."

"As for the rotor system, the most critical blade, we can make full use of the material advantages of Nanshan carbon fiber to give an innovative solution."

"Once the technology of these three core components has been solved, we can completely produce the helicopter ourselves."

"As far as the domestic civil helicopter market is concerned, it is still very huge."

Cheng Tao and Ji Hua together were very active in proposing to Cao Yang that Nanshan Group enter the helicopter market.

The Nanshan Group already has a large-scale drone business, and it seems that it has plans to further enter the aerospace field in the future.

In this case, it is naturally not impossible to engage in helicopters.

Even now, the idea of making a small business jet is already being considered.

In this case, it is not too exaggerated to simply go further and produce helicopters.

After all, Nanshan Group has developed to the present, and if it wants to continue to expand its influence, it is naturally necessary to enter some new fields.

With the development of gasoline vehicles, there is relatively little room for technological progress in engines and gearboxes.

What projects the relevant technical personnel need to continue to be responsible for in the future is something that Cheng Tao and Ji Hua need to consider in advance.

Although there are some new attempts, they don't think it's enough.

"I recently heard news that China intends to relax the aerospace-related entry threshold for private enterprises."

"In the future, not only helicopters can be produced by private enterprises, but rockets and satellites can also be produced by private enterprises."

"The specific policies of the relevant aspects will be announced in the second half of this year if they are fast, and it is estimated that they will be announced next year if they are slow."

"It's not impossible to do some advance layout now."

As soon as Cao Yang said this, the smiles on Cheng Tao and Ji Hua's faces couldn't be hidden.

If the Nanshan Group wants to produce helicopters, then the transmission system can be completely handed over to the Nanshan gearbox.

Needless to say, the engine must be handed over to the Nanshan gearbox to correspond.

Nanshan Group has a special accumulation in material science, and it is entirely possible to produce some surprising results when the time comes.

After all, the improvement of engine performance is closely related to material science.

There will even be a situation where the relevant departments will find Nanshan Group to produce the helicopter final reducer because it can be designed but cannot be produced.

"SpaceX in the U.S. is already working on recyclable rockets, although it's not sure when it will actually succeed."

But in 2008 the company announced that it had been awarded a $1.6 billion contract by NASA for commercial resupply services to ensure the resupply of the International Space Station after the shuttle was retired in 2010.

"And in '09, they announced that they had sold 14 contracts for various Falcon launch vehicles."

"Although there has been less news about this company in the past year or so, it is estimated that there may be a big satellite released when people will release it."

"In this case, the domestic call for the opening of the aerospace industry is becoming higher and higher."

"I think that since Mr. Cao, you have heard this rumor, it means that this matter will soon be landed."

"Our group has huge technical advantages in carbon fiber, special steel, engines and other fields, and it is completely possible to enter the aerospace industry at that time."

Cheng Tao is looking forward to the future.

Although he is not good at aerospace-related fields, he is full of enthusiasm when he imagines that the company will be involved in such projects in the future.

At his level, financial freedom has already been achieved.

Nowadays, what I am pursuing is more of a sense of achievement.

Obviously, the aerospace industry is an industry that is very easy to bring a sense of accomplishment to everyone.

"Satellites, rockets, airplanes, helicopters, any of these products, it's very challenging to make a breakthrough."

"However, with the development of Nanshan Group now, it is really necessary to challenge some difficult things."

"Do you have any acquaintances and friends who are engaged in this work, you can ask them if they are interested in working in Nanshan Group."

"Our group's aerospace industry will be a fresh start."

Cao Yang's words mean that Nanshan Group has officially decided to enter the aerospace industry.

This time, it's not about making a little bit of a fuss about drones, but about moving towards the big guys of rockets, satellites, and airplanes.

……

As the liaison representative of the special department in Nanshan Group, Pan Jun is still familiar with many things in Nanshan Group.

And the various trends of Nanshan Group are also very concerned about him.

Cao Yang decided to enter the aerospace industry, and he naturally cared more about it.

After all, this field, no matter how you listen to it, will make people associate it with military technology.

After all, some large rockets, as long as they are slightly changed, are missiles.

And it's still the kind with a relatively long range.

As for satellites and airplanes, this thing can definitely be linked to military technology.

So after this situation, he immediately reported to the above.

For the sake of Pan Jun's report, the relevant departments also held a special meeting to discuss it.

"In recent years, Nanshan Group has brought a lot of surprises to everyone, and our aircraft technology has made huge breakthroughs in recent years, which has a very close relationship with Nanshan carbon fiber."

"Other changes in rocket and satellite technology are also closely related to the application of carbon fiber."

"Nanshan Special Steel has even participated in the research and development of aircraft carrier steel plates, and has made great contributions."

"As for the twin-tailed scorpion drone, which has recently become the new darling of the air force/army, it is needless to mention."

"These achievements, which are real, have nothing to do with the efforts of all of you here."

"These achievements are also much greater than many enterprises and scientific research institutes that spend a lot of money every year."

"Now that Nanshan Group is preparing to enter the aerospace industry, I don't think there is any need to interfere with others."

"Anyway, people are burning their own money, and they don't ask everyone for a penny."

"Once they do make some name for themselves in the future, we can also buy their products and transform them."

"There are some large private arms companies abroad, and I think Huaxia can have them."

An old man with two gold stars on his shoulders couldn't help but stand up and express his opinion directly, seeing that everyone present said everything.

Even aerospace technology is more sensitive, and it is easy to leak secrets when it is developed by private enterprises.

The threshold for these technologies is very high, and it is impossible for private enterprises to make any achievements or something like that, and he doesn't really want to hear it now.

Civil-military integration is the general direction of the future.

He was well aware of the situation.

So the attitude is very firm.

"I also don't think I need to worry about things on the Nanshan Group's side."

"Their Cao is always a very measured and patriotic entrepreneur."

"In recent years, Nanshan Group has won awards such as the National Science and Technology Award, and there are few domestic enterprises with a higher technical level than them."

"And their decision-making system is relatively flexible, as long as Cao Yang goes down with a word, any resources can be equipped."

"In recent years, Nanshan Group's profitability has been very good, and there is enough money to engage in research and development."

"To put it mildly, even if it burns tens of billions of dollars, and in the end no products are made, Nanshan Group will definitely be able to make some technological breakthroughs in the process of burning money."

"These technological breakthroughs may have a very good effect on some other industries."

Another participant also came forward to express his opinion.

Soon, the atmosphere in the venue began to change.

Everyone's opinions have begun to develop in the direction of supporting the Nanshan Group to engage in aerospace, and everyone should not interfere more.

Cao Yang naturally didn't know this information.

However, invisibly, it has promoted Huaxia's faster opening up of the aerospace industry to private enterprises.

It has even further contributed to the management of low-altitude airspace.

……

"Ayang, the aerospace field is very expensive, are you sure you want to enter this field in an all-round way?"

Fang Sisi rarely interfered in the affairs of the Nanshan Group.

But that doesn't mean he doesn't care about the company's development.

Son Cao Zhiyuan is more than half a year old and is ready to be weaned.

She also began to slowly return to the workplace and continue to be in charge of Weibo.

In the past year, she has exchanged a lot of Internet-related things with Cao Yang, and she also has many ideas about some future investment directions of Weibo.

Even during her sabbatical, she arranged for someone to set up an investment department within Weibo, specializing in a business similar to venture capital.

This is something that many Internet companies have not done.

Large-scale Internet companies such as BAT will consider it.

Compared with the aerospace industry, she feels that the Internet industry is more favored by capital, and the return on capital investment is higher.

So when she heard that Nanshan Group was preparing to vigorously enter the aerospace field, she couldn't help but chat with Cao Yang.

"Last year, Nanshan Group earned more than 100 billion yuan, and if the money is simply used to develop existing industries, it will not be used at all."

"It's not a good thing if there are more than 100 billion more in the bank every year, or even hundreds of billions more a year."

"For us, more money is not necessarily better."

"It's better to spend this money on some key technology areas and see if we can make some breakthrough developments."

"In this way, we will be more secure in the future."

Facing Fang Sisi, Cao Yang naturally had no need to hide his true thoughts.

Although most of the shares of Nanshan Group are owned by their own families, these companies can no longer simply regard them as their own family business.

After the scale of the enterprise is large, its development must be closely related to the fate of the whole China.

Only when the whole of Huaxia becomes stronger, the future of Nanshan Group and Cao Yang is more worth looking forward to.

Otherwise, it would be the same as now, Cao Yang didn't even have the idea of going abroad to participate in any activities.

Even many technical experts of Nanshan Group are now very cautious about going abroad.

"That's right, my uncle was a little worried that you wouldn't be able to see through it."

"However, the money in aerospace is likely to burn tens of billions a year, but there is no achievement."

"After a long time, the money burned may not be less than that of Nanshan Semiconductor."

"The most important thing is that the money is burned, and it is likely that there will be no results."

Fang Sisi is not such a material person.

Of course, this has something to do with the current situation.

She is no longer short of money, and naturally there is no need for material things.

"When the money is spent, there will definitely be results, it's nothing more than a matter of size."

"I'm wondering if we'll be able to retire on the moon or some other planet in the future."

"It's a bit difficult to get good results in three or five years, but there will still be breakthroughs in ten or eight years."

"In fact, with the development of technology, many things are just a step away."

"Fifty years ago, people would have been able to go to the moon and produce large airplanes that we can't produce now."

"We are now integrating resources from all sides and closing the gap between the past few decades, and there is obviously no problem."

Cao Yang is well aware of the breakthroughs that China will make in aerospace in the next decade.

This shows that the technical threshold of many things has actually reached the point where it can be broken at any time.

Nanshan Group now has more than 180,000 employees, most of whom are technicians and R&D personnel.

The energy that these people burst out with the motivation of high salaries is very amazing.

When the time comes, Nanshan Group can come up with a few products that will surprise everyone.

Cao Yang is very confident in this.

"Since you have confidence, then be bold and do it."

"I can help get in touch and see if we can find some technical talents from the aerospace institute who are interested in jumping out of the development."

The Fang family's network is naturally far from being comparable to the Cao family.

Some people you simply rely on headhunters to dig, and you may not even be able to find the door.

Even if you dig it, you won't be able to dig it.

But once you've found the right person to talk to, maybe it's a completely different story.

This is still very important for Nanshan Group to enter the aerospace industry.

To a certain extent, if this kind of poaching is successful, it can even be regarded as officially recognized and acquiesced.

"That's the best!"

"It would be better if there were some retired veterans who were interested in joining in."

For Cao Yang, innovation is not what he lacks the most, what he lacks is some professional and technical personnel in the aerospace field to implement his "innovation" ideas.

For those retired veteran experts, the basic skills are definitely very solid.

They can even help bring newly recruited college students into the right track, laying a solid foundation for the development of Nanshan Group's aerospace industry.

"Retired old specialists?"

Fang Sisi's eyes lit up, "This is a breakthrough." ”

"After many old experts retire, their physical condition is actually quite good."

"Even if there is something to do, it is good for their health."

"When the time comes, digging up some employees, recruiting a group of fresh graduates, and then combining them with retired old experts, may be able to play an unexpected role."

Fang Sisi still has a good understanding of the situation of those retired employees.

There are really a lot of people who have real skills.

The most important thing is who has the ability and who is the coward, basically everyone knows.

When digging people, you don't have to worry about pits.

At that time, the aerospace industry of Nanshan Group is really worth looking forward to.
