"Fourth-generation aircraft...A real fourth-generation helicopter?"

Hearing Zhuang Jianye’s words, the others were still at a loss, but the military leaders who had been dealing with equipment for half a lifetime said with a deep voice: “Compared with the previous generations of helicopters, the fourth-generation helicopters are both in materials, power and avionics. It has made great progress. Ascendas Group and Cidu Helicopter Factory are cooperating with Zhi-8MAX in terms of power and materials. The avionics may be inferior to foreign countries, but it is barely enough... …"

Major leaders in the military are worthy of being experts in the field of equipment. When it comes to the advantages of helicopters and various manufacturers, it can be said that they are precious.

The fact is indeed the case. Ascendas Group does not lack materials, power and craftsmanship in helicopters. What it lacks is experience in system integration. Therefore, the cooperation with Cidu Helicopter Factory has made up for this disadvantage.

Take the current Zhi-8MAX as an example. It uses two WD-63ZB turboshaft engines with a power of 2484 kilowatts, equivalent to 3377 shaft horsepower.

The engine is based on the WD-63Z high-power turboshaft engine equipped with the Zhi-8plus heavy-duty helicopter, after reducing the two-stage high-pressure compressor and one-stage low-pressure turbine, and adding noise suppression function to improve it.

Of course, if it is in other countries, a 1800 to 2000 kilowatt turboshaft engine is sufficient for a special helicopter used at sea. After all, the maximum ceiling of this type of naval-equipped carrier helicopter is 3500 meters. After all, it is a helicopter used for low-altitude anti-submarine, it is useless to fly high.

But there is no Qinghai-Tibet Plateau with an average altitude of more than 4,000 meters in China. Who can guarantee that the Zhi-8MAX cannot go from sea to land, and it will be matched with its brother Zhi-8plus heavy helicopter to become the air galloping on the plateau. Qingqi?

In addition to the lessons learned by Ascendas Group’s misconsideration during the Zhi-12, Ascendas Group is very stubborn to equip the Zhi-8MAX with a more powerful turboshaft engine.

Not only that, Ascendas Group has also made great efforts on the materials of Zhi-8MAX.

In the past, even if the helicopters used composite materials, they were basically concentrated on secondary bearing structures such as skin and floor. The main bearing structures such as frames and truss beams still used metal materials such as aluminum alloy or even steel.

Even the Zhi-8plus heavy helicopter did not escape from this pit, and the use of composite materials did not exceed 25%.

But when it came to Zhi-8MAX, the proportion of composite materials used suddenly increased by 55%. Not only did the skin and floor use composite materials, but even the box-shaped frame as the main bearing structure used the high-strength developed by Tengfei Group Carbon fiber composite material.

In other words, except for technical reasons where composite materials cannot be used, the other places where composite materials can be used have not fallen behind.

The reason for using composite materials on such a large scale is not that Ascendas Group announced to the world how NB it is in composite materials in order to play cool tricks.

It was forced to increase the amount of composite materials used as much as possible.

No way, who made the Zhi-8MAX the first priority is to be used as a navy shipborne helicopter.

The high salt and high humidity on the sea are inherently corrosive to equipment. General metals will not last long without special treatment. Compared with composite materials, composite materials have natural advantages in corrosion resistance.

In addition, the domestic technology on the surface corrosion-resistant treatment of special metal is still not enough, so after some weighing, Ascendas Group still chooses its own better composite materials to deal with the corrosion resistance of the body.

In this way, the Zhi-8MAX was created, the aircraft with the highest proportion of composite materials in domestic aircraft so far.

Now, this also brings a bad consequence, that is, the configuration of the engine and materials is too high, leading to a sharp increase in costs.

Coupled with the complicated processes involved in the special processing of 2500 kW scroll shafts and large-scale composite materials, the already high cost has been further pushed up.

As a result, the unit price of a well-equipped ship-borne anti-submarine Zhi-8MAX reached 528 million yuan, almost twice that of the Zhi-8plus heavy helicopter.

The unit price of the Zhi-8MAX premium VIP "Marine Corps One" for high-end people has reached a record 900 million yuan, which is actually higher than the unit price of Yun-18NB.

Of course, Zhuang Jianye did not disclose the price of these things to the leaders, otherwise this group of people would definitely say that the biggest thing about the 8MAX is that it is quiet, and it is clearly expensive!

In order not to let the vulgar things like money hinder the Tengfei Group from holding the thighs with the seniors, Zhuang Jianye's face is not red and heartbeat. It is not a matter of this kind of thing. As for whether the big leaders will be speechless in the future, it is not his business. Up.

Anyway, the thigh has been hugged, want to shake it? No way!

But then again, even if the military leaders know that the price of the 8MAX is expensive at this moment, the military leaders at this moment don't have the thought to be stunned, because after a lot of inventory, the military leaders are already in their hearts. The idea was so shocked that he frowned and muttered inconceivably: "It should be impossible... But if it is not, how can it be called the fourth generation... But if it is the fourth generation, it must be..."

Then he raised his head and looked at Zhuang Jianye with some inconceivability, and asked with some uncertainty: "Don't you have mastered the core technology of the ball flexible hub?"

In fact, Zhuang Jianye would like to say that they have already mastered a generation of bearingless hubs that are more advanced than the spherical flexible hubs and have applied them to the Z-12 verification machine.

If it were someone else, Zhuang Jianye would have the courage to lean on the bearingless hub. As long as he can get more funds, how to get advanced has become the industry rule~lightnovelpub.net~ Zhuang Jianye is not a saint, so he can get more. Why can't the funding be advanced?

Let me tell you, [\\mi\\mi\\read\\app\\\\] really good, it's worth installing, even Android and Apple phones support it!

The problem is that the military leaders in front of him have used equipment for most of his life. Zhuang Jianye does not believe that such people will not know that due to the characteristics of materials, bearingless hubs can only be promoted on light helicopters. Large and heavy helicopters can only be promoted due to swinging. The torque is too large, and there is no composite material that can withstand it, so even if you want to apply it, there is no way to continue to use the traditional hub structure.

For example, the Zhi-8plus heavy-duty helicopter uses the all-metal articulated hub of the Zhi-8 old model.

Not only the structure is complicated, but also the noise is extremely loud. Because of this, the Zhi-8plus heavy helicopter can only stay in the category of the third-generation helicopter, which can be counted as 3.5-generation at most.

Because the hub used in the fourth-generation helicopters, especially the fourth-generation large or heavy helicopters, is no longer a complex all-metal articulated or semi-articulated hub, but a spherical flexible hub that uses a lot of elastic materials.

Obviously, the leaders of the military can say the term spherical flexible hub, which shows that he is very clear about the difference and application scope of bearingless hub and spherical flexible hub.

Therefore, Zhuang Jianye could only sigh in his heart. When he met a savvy leader, he lost at least 200 million in funds, but he was still quite excited to compliment the military leaders: "The chief is really amazing. —8MAX uses a spherical flexible hub, which is amazing~~great~~"

However, the military leaders ignored Zhuang Jianye's compliments. Instead, with a look of excitement, he took a step forward and continued to ask with a trembling voice: "So, have you broken the elastic bearing technology?"
