Pan Jun hoped that the Nanshan Group would produce more military products, or more products that could be used in the military industry.

At this point, in fact, Daystar Technology has not stopped the pace.

Just when the outside world was still discussing the matter of "island-building artifact", Cao Yang had followed a group of executives from Nanshan Special Steel, Nanshan Equipment and Daystar Technology to the heavy-duty transport helicopter production plant to watch the official mass production of the newly finalized drive shaft.

In the past two years, Daystar Technology has been referring to the American Chinook helicopter to develop a fist product belonging to Daystar Technology.

Don't look at this helicopter, the Americans have been producing it for decades.

At that time, Huaxia also obtained a prototype through Annan, but this prototype has been in Huaxia for half a century, and in the end, there has been no way to imitate it.

When many of the polar bear's products arrive in China, we can localize them and imitate them.

Why can't this heavy transport helicopter handle it?

The core problem here is focused on the drive shaft.

It is a seemingly simple shaft, which has simply become an insurmountable technical unsolved.

"Mr. Cao, because the transmission shaft of this transport helicopter is composed of seven sections, not only the torque is huge, but it is accompanied by obvious vibration."

"We needed to design the shaft to be lightweight and reliable at the same time."

"This seemingly contradictory need makes the road to imitation of Chinook helicopters fraught with insurmountable technical dilemmas."

"Daystar Technology can handle this axis, which is definitely a very remarkable achievement."

Pan Jun also came to the scene with Cao Yang today.

As a representative of the relevant departments, he has a better understanding of the history of the imitation production of this helicopter.

Because of this, he heard that Daystar Technology had solved the problem of this shaft, so he must come to the scene to take a look.

"The core problem with the propeller shaft is its high torque and very long length."

"In this case, how to find the right materials and processes is the most difficult problem."

"The material must not only meet the torque and length requirements of the shaft, but also be durable and stable."

"Fortunately, our Nanshan Special Steel has accumulated a lot of experience in related special steels before, otherwise it would be really difficult to find suitable materials this time."

Xie Lingyun can be regarded as one of the protagonists today.

After all, one of the core things of the drive shaft is whether the special steel meets the requirements.

"We haven't done it for decades, but the United States has done it so early."

"I simply suspect that the United States was using extraterrestrial technology at that time."

Pan Jun couldn't help but make a joke next to him.

The level of technology in that era was relatively low, and it was indeed very difficult to solve such a huge and complex problem

But people have solved it, and you really have to admire.

"The imitation of the propeller shaft is not only a technical challenge, but also a great test of material science and process technology."

"The design and manufacturing need to meet strict standards, which are not only about torque and length, but also about the quality, durability and stability of the shaft."

"How to find the right balance in these aspects is a topic that everyone needs to continue to explore."

"In the past, Huaxia had many deficiencies in material science and process technology, which made the imitation work a huge and complex system engineering."

"It's a completely different situation now, and although the threshold is still very high, we are able to reach it."

"Even the drive shafts we produce now can be better in terms of material properties and machining accuracy."

Cao Yang understands technology, and naturally he can understand how difficult the design and production of the drive shaft in front of him is.

As a rigid connection part connecting the front and rear propellers, it is one of the most technically demanding parts in heavy transport helicopters.

This is a bit inconsistent with many people's perceptions.

You may always think that Huaxia is not good at the level of helicopter engines, so there is no way to produce heavy helicopters.

Or there are deficiencies in the design of the flight controller or propeller, which leads to the difficult production of related products.

In fact, those problems also exist, but they can be solved relatively speaking.

If you really can't do it, you can also consider buying it from the polar bear.

But this drive shaft has been bothering everyone for many years.

Now that it's finally resolved, the meaning is really extraordinary.

"With a length of more than 20 meters, the shaft not only transmits more than 3,000 horsepower, but also does not resonate during transmission."

"Polar Bear used to imitate and produce this helicopter back then, but due to material and design problems, the propeller shaft resonated during the flight test, and the body almost fell apart."

"After that, the polar bear also gave up the imitation work."

Pan Jun half-jokingly added the story that happened to Big Brother back then.

This shows that it's not that Huaxia's level is not good, it's that the difficulty of this thing is too high, so except for the United States, no one else can handle it.

"In order to produce this special drive shaft, we at Nanshan Equipment have specially developed and produced a large CNC milling machine for roughing and finishing the shape and key dimensions of the drive shaft."

"This CNC milling machine is five-axis linkage and can achieve complex chip paths and angles."

"Then we also specially developed a special high-precision grinding machine for high-precision grinding of the drive shaft, ensuring surface finish and dimensional accuracy."

"At the same time, because there is a deep-hole structure inside the drive shaft, we have also developed a deep-hole drilling machine for machining."

"As for other special machine tools, we also develop special machine tools and fixtures according to the specific structure and processing needs of the drive shaft."

"These thresholds alone are really not something that ordinary enterprises can handle."

For such a critical part, the requirements for processing equipment must also be very high.

As the person in charge of Nanshan Equipment, Pan Jinxing must also take this opportunity to show their efforts.

Fortunately, there are many types of products in Nanshan equipment, although more than a dozen processing equipment has been specially developed this time, but most of the equipment is actually a prototype product, but it needs to be specially produced and transformed.

Otherwise, the investment in equipment alone would be astronomical.

The market demand for heavy-duty transport helicopters is relatively small, and the amortization cost of equipment on each propeller shaft is very exaggerated.

You must know that as the king of this field, the "Chinook" has been sold for half a century, and it has only sold more than 1,000 units.

The external price of this helicopter is more than 100 million US dollars.

The performance of similar products produced by Daystar Technology must be developed in a better direction than it, but the final price must not be more expensive than that sold in the United States.

According to Cao Yang's idea, it is best to be able to control it within 100 million yuan.

Otherwise, it is estimated that the purchase volume of the relevant departments will not be very large.

Of course, the price of 100 million yuan is for the relevant departments of China.

If it's an export, then just a little lower than the United States.

My performance is better, the price is lower, and the prospect is still worth looking forward to.

"Academician Pan is right, if it weren't for the fact that Nanshan Equipment could produce a variety of high-precision large-scale machine tools this time, our drive shaft would not have been able to produce it."

"The equipment industry is advanced enough, and then the materials industry is able to meet the requirements, and many of our parts can be produced."

Zhao Siyu, as the general manager of Daystar Technology, naturally came over to confirm it on the spot today.

Although Daystar Technology has Daystar 9 and Starlink, which are sensational projects around the world, this project still feels too far away from them to many people.

The situation is similar for twin-tailed scorpion drones and Golden Eagle unmanned helicopters, which are rarely seen by ordinary people.

But the situation with heavy transport helicopters is slightly different.

As long as it is made and everyone finds it to be very useful, then maybe every major city can see it.

Even the relevant departments will make large purchases, which can often be seen in various exercises and news.

In the future, it can also be used as the fist product of Daystar Technology for export to the outside world, and become a bright business card of the company.

Therefore, Zhao Siyu has very great expectations for this heavy-duty transport helicopter.

"Mr. Cao, the most troublesome propeller shaft has been solved, so will this heavy-duty transport helicopter belonging to Daystar Technology soon enter the state of mass production?"

Pan Jun looked at Cao Yang expectantly.

As a representative of the relevant departments, he is too aware that many teams in China have the need to use heavy transport helicopters.

Let's not talk about whether the performance of this product made by Daystar Technology is really better than that of the United States, as long as it can achieve the same performance, or even slightly worse, the significance is extraordinary.

Therefore, Pan Jun really hopes that Daystar will put it into mass production as soon as possible.

"The R&D progress of other parts is basically faster than that of the propeller shaft."

"Now that the drive shaft has entered mass production, the whole machine can naturally start to be assembled."

"However, after assembly, a series of tests are still needed to confirm whether all aspects of performance meet the design requirements."

"Maybe after some problems are found in the design process, appropriate improvements need to be made."

"So the final mass production time should go until next year."

Cao Yang also very much hopes to mass-produce heavy transport helicopters immediately, but this kind of high-tech big guy can't be done in a day or two.

Recently, we have assembled a few test products, which is already very remarkable.

"It can be launched next year."

"Soon it will be the Imperial Capital Air Show, can we transport the prototype over to show it at that time, and let everyone see the power of Daystar Technology?"

When Pan Jun mentioned this, both Cao Yang and Zhao Siyu were interested.

Although the influence of the Imperial Capital Air Show is not particularly large, as long as there are blockbuster products launched during the exhibition, the influence will naturally go up.

At that time, there is no need for Daystar Technology to publicize it itself, and various media will rush to help promote and introduce this heavy transport aircraft.

"Mr. Cao, I think you can indeed consider participating in the Imperial Capital Air Show."

"Heavy transport aircraft are both military and civilian, and it's time for us to start marketing to increase our sales as much as possible."

"If we can produce more than 500 units in the next three years, then our various amortizations can basically be completed quickly."

"If we continue to sell in the future, the profit margin of the product can rise to a relatively considerable level."

Zhao Siyu felt that it was completely okay to take the opportunity of the Imperial Capital Air Show to promote it.

I wasn't sure when I could get the drive shaft before, and I hadn't participated in the Imperial Capital Air Show, so Zhao Siyu really hadn't thought about it.

The "Chinook" in the United States has been sold for half a century, and more than 1,000 units have been sold, and Daystar Technology naturally does not dare to set the apportioned sales of heavy transport helicopters too high.

Otherwise, the various investments will not be amortized at that time, and the calculated costs will be problematic.

Then the set selling price will be a loss-making price, which is definitely not good.

Therefore, combined with the needs of all aspects, Daystar Technology has set a sales target of 500 aircraft in 10 years.

Based on this goal, various expenses such as capital investment will be amortized.

Of course, if it is an export, an additional high price will be set.

How to calculate the cost of this part is a more complicated problem.

Now, if it is really possible to sell 500 units of products within three years, then whether it is sold to domestic or foreign users, the significance is extraordinary.

"If you want to exhibit, wouldn't it be better to have a more impressive name?"

Pan Jun interjected beside him.

"Mr. Cao, we have also had some internal discussions about the name."

"The names Kunpeng, Eagle, and Daystar No. 1 are relatively loud, which one do you think is better?"

After listening to Pan Jun's words, Zhao Siyu immediately took out his plan.

This kind of thing must have been discussed by the internal team of Daystar for a long time, and it is impossible to start the name when it is really time to mass produce and sell.

"Just Kunpeng."

"The Kunpeng heavy transport helicopter should still be worthy of its name."

Naming this kind of thing, Cao Yang feels that it mainly depends on feelings.

Anyway, they were all nominated by Daystar Technology, and some obvious problems must have been avoided.

For example, names such as bad homophony and ominous symbols can't reach Cao Yang's side.

"Kunpeng?"

"There is a fish in the North Underworld, and its name is Kun. The Kun is so big that I don't know how many thousands of miles it is. Turned into a bird, its name is Peng. Peng's back, I don't know how many thousands of miles it is; Flying in anger, its wings are like clouds hanging from the sky. ”

"That's a good name!"

Whether it is really good or blurted out flattery, Pan Jun must express his support and recognition at this time.

After all, this kind of thing has nothing to do with him.

I just mentioned it, and people immediately implemented it.

This is to save face.

"As our largest heavy-duty transport aircraft in China, and even the world's largest heavy-duty transport helicopter, the name Kunpeng is really very consistent."

"Mr. Cao, then we will start preparing for the first batch of prototypes of the Kunpeng heavy transport helicopter today, and then arrange a special train to transport it to the imperial capital for display."

Zhao Siyu immediately began to arrange the next step.

However, Cao Yang has his own ideas about this arrangement, and said: "There is no need to use the train to transport it so troublesomely." ”

"Aren't we going to run tests?"

"There must also be a long-distance flight test, so we just coordinate with the relevant departments, and we will fly directly from Yangcheng to the imperial capital."

"However, the fuel supply along the route should be well coordinated, and if there is a situation that needs to be repaired and refilled, you can also know what to do."

"Considering that it is still being tested, the flight process is also to avoid densely populated areas as much as possible."

Since they have to be taken out and displayed, they naturally don't have to worry about flying into the sky and being photographed and spreading.

In this case, flying over is a good solution.

Anyway, in the case of no load, the Kunpeng can fly more than 2,000 kilometers, and the final data can also be tested by taking this opportunity.

After all, compared with the "Chinook" in the United States, Kunpeng uses a large number of carbon fiber materials and other most advanced materials in the new era, and the weight of the whole machine has actually decreased.

The power of the engine developed by Nanshan Engine is not worse than that of others, so it is not surprising that the final cruising range is longer than that of the "Chinook".

People can fly 2,250 kilometers, and it is entirely possible for Kunpeng to come up with a limit flight distance of 2,500 kilometers or even 3,000 kilometers.

Even when the time comes, the engine can be upgraded on the basis of the existing version, so that its load can be further improved, and it will become the world's largest heavy transport helicopter.

At that time, if Daystar Technology wants to promote Kunpeng, it will be much less difficult.

"It's a good idea, and the publicity should be better."

"When the time comes, we can even give a special paint scheme to make the Kunpeng heavy-duty transport aircraft more special and more conspicuous."

Zhao Siyu thought about Cao Yang's plan for a while, and felt that the feasibility was still relatively high.

Although there is a certain risk, such as breaking down halfway, this probability is relatively low.

In the early stage, Daystar Technology has carried out various internal verifications, and it stands to reason that there is no major problem.

In addition, the design of the Kunpeng in all aspects such as appearance and styling has a reference to the "Chinook", which ensures that as long as there are no problems with the various parts, the final result will not be too bad.

Not to mention the enhanced technology on the Kunpeng.

"I can help you with things like finding relevant departments to coordinate the application for routes."

"There may even be people in the relevant departments who are interested in participating in this test."

Pan Jun took the initiative to stand up and offer to help.

He is also a person with eyesight, and this kind of thing is a win-win thing.

Maybe he offered to help here, but in fact, after the relevant contact started, he didn't need to do anything at all, and someone helped to get everything done.

The relevant departments have been engaged in heavy transport helicopters that have not been done for decades, and Daystar has done it here.

At this point, there must be a lot of agencies that want to help.

"With Representative Pan coming out, things are even simpler."

"We can also directly arrange for the twin-tailed scorpion drone to fly next to us and conduct relevant filming throughout the process."

"Maybe at a later stage, it can be directly taken out and used as promotional materials."

Since the Kunpeng heavy-duty transport helicopter is to be developed as the fist product of Daystar Technology, the relevant publicity will naturally have to keep up.

In this day and age, good products also need publicity to exert the greatest impact.

Otherwise, it would be a pity then.

"Mr. Cao, hasn't Zhang Xin been engaged in the filming of "The Wandering Earth" all the time."

"Many of Daystar Technology's products have been implanted into this movie before, and I think the Kunpeng heavy-duty transport helicopter can also be implanted into it."

"It just so happens that such a large transport helicopter has the opportunity to be implanted in many movies, and it can slowly leave a deep impression on everyone."

"Judging from the situation in the United States, our Kunpeng will be sold for at least twenty years in the future."

"A lot of marketing strategies are about long-term demand."

Mi Ying, who had been following Cao Yang and hadn't spoken much, interjected at this time.

She is responsible for coordinating Cao Yang's schedule and liaising with all parties, and her knowledge is actually very wide.

Zhang Xin is Cao Yang's cousin again, and Mi Ying is naturally more concerned about her affairs.

"Director Mi's proposal is very good, and Kunpeng is indeed very suitable for advertising placement in many movies and TV series."

"Especially movies related to military themes or science and technology themes, you can basically find relevant shots."

Zhao Siyu listened to Mi Ying's words, and immediately expressed his approval.

This kind of thing is definitely good for Daystar Technology.

"Then do as you say, Mr. Zhao, you can make a call to Nanshan Film and Television, and ask them to consider Kunpeng's advertising placement in the future."

"Even if necessary, it is no problem for us to arrange a Kunpeng to cooperate with the film and television shooting."

This kind of thing that is obviously beneficial to the company, Cao Yang naturally agrees without any hesitation.

And he thinks that after Nanshan Film and Television has made this start, maybe other film and television companies will be interested in the future.

At that time, Daystar Technology may not only not need to pay for advertising placement, but also find someone to charge some fees for assisting in shooting.

The core part of the propeller shaft has been completed, and the heavy-duty transport helicopter belonging to Daystar Technology is about to be launched.

The Chinese helicopter industry will soon enter a new era.

Because a lot of the technology on this helicopter can actually be used on other types of helicopters.

In the future, it is expected to drive the rapid development of the entire industry.
