Chapter 566 Thirty Years in Hedong, Thirty Years in Hexi
The power system adopted by the lift fan is a turbine engine and multiple rotating propellers, which can generate a large amount of thrust.
The fan itself is a huge propeller that rotates at a high speed to generate airflow downwards, thereby generating vertical downward lift, thereby achieving vertical take-off and landing and hovering.
Therefore, lift fans are widely used in military, civil and scientific research fields.
On fighter jets, the purpose of matching lift fans is to balance the component force of the rear turbofan engine, such as F-35B and Harrier fighter jets.
Of course, only the vectoring nozzle can achieve vertical downward thrust, and the thrust of the front lift fan is relatively small, so the center of gravity is required to be as far back as possible.
Muyang's Flying Dragon ground effect aircraft requires four 02J afterburning turbofan engines and four lift fans, and the full thrust of each lift fan is required to be 15 tons.
Many factors need to be considered in the manufacture and design of lift fans, such as the material, shape, size, etc. of the rotating propeller, that is, the blades.
The most difficult thing to manufacture is of course the blades. The mass of the blades of the lift fan accounts for most of the weight.
If the individual blades are heavy, they cannot rotate fast, and generate huge horizontal forces, wear out too quickly for the rotating shaft, and become unstable.
Therefore, the material of the blade is required to be low density, such as titanium alloy or aluminum alloy.
Low light density is not enough. It is better to have a hollow structure inside the blade to reduce weight.
Xinghai Group has metal 3D additive technology, making blades is too easy.
For Xinghai Group, how to increase the thrust ratio of the lift fan is important.
Mu Yang came to the laboratory where the lift fan was researched. The project leader saw the chairman come to investigate and helped him introduce the project results.
"What is the ultimate thrust ratio?"
"The weight of a single lift fan is 4.3 tons, the full thrust is 15.5 tons, and the thrust ratio is 3.60."
"Okay, not bad, what's the rotational speed at full thrust?" Mu Yang praised, this thrust ratio is extremely high, generally it can rarely reach more than 3, like the thrust ratio of the lift fan of the F-35B fighter jet is 2.
This is not a turbofan engine after all.
Thrust has a lot to do with rotational speed, blade structure and duct diameter, and the thrust ratio has a lot to do with the weight of the lift fan. Xinghai Group’s lift fans can have such a high thrust ratio mainly because the blades are very light in weight, but the structure The intensity is not bad.
"14,500 per minute."
Mu Yang nodded. In fact, the lift fan is not so magical. If it is not for the vertical take-off and landing in a small space, in order to be able to hover in the air for observation or search tasks, in terms of speed and carrying capacity, it is not as good as the combat power without the lift fan.
The lift fan increases the structural complexity of the aircraft and adds weight, and it does not operate when flying at high speeds.
Like the F35B, when lifting vertically, the top ventilation cover of the lift fan should be opened, and then the cover should be closed when it can fly horizontally, and the lift fan should be stopped at the same time.
Similarly, Muyang's ground-effect aircraft must also turn off the lift fan after flying.
If it is not for vertical lift, taxi take-off and landing are also fine, and the lift fan is removed, saving nearly 20 tons of gravity.
But there are also great advantages, the lifting and falling can be controlled very well, and it is relatively safe.
This ground effect aircraft project has a total of three cores, lift fan, 02J engine and balance system.
At present, the three cores have been completed, and the large-scale assembly has begun. If it goes well, it is expected to complete the large-scale assembly and test flight in about four months.
Wingspan: 85-90 meters, captain: 80-90 meters, height: 15-17 meters.
The headquarters base of Xinghai Group cannot carry out large-scale assembly, and it is not suitable for test take-off after assembly.
The large assembly plant is in the rocket manufacturing plant in Yangfu District, where there is enough workshop space and open space, and it is also very close to the Qianjiang River, and then it will be driven to the sea for high-speed tests.
The rocket base has more space, but it is a little troublesome to transport it there.
However, Mu Yang still suggested to communicate with the relevant departments first. After all, the ground-effect aircraft is not simple, and it will be troublesome not to allow a test flight after the assembly is completed. It can only be disassembled and put in the rocket base for assembly and then tested in the sea.
When Mu Yang reported the news to someone, the other party was very shocked.
"Have you developed an afterburning turbofan engine with a thrust of 100 tons?"
"Yes, the test has been successful, and it is planned to be applied to an aircraft."
A few days later, I came to Xinghai Group for inspection.
After a few hours, the satisfaction left.
After another day, I got a reply: At that time, the surrounding area will be controlled, and a low-speed test run can be carried out on the Qianjiang River; if you fly, you need to report the route.
No matter where the test flight is, there is no way to hide from the outside world that the ground effect aircraft, a big guy, will not be in any danger when running at low speed on the Qianjiang River.
Mu Yang was very satisfied with the reply from the relevant department, and then issued an order: starting today, the ground-effect aircraft will enter emergency assembly.

August 10,
The desert greening was officially launched, and the treatment location was in the desert area 50 kilometers northwest of Zhongwei City.
This area is also where the Ant Forest will be governed in the future, covering an area of about 60,000 square kilometers.
When the Xinghai Group announced desert control, domestic environmentalists strongly supported it.
At present, Xinghai Desert Greening Co., Ltd. has more than 500 employees, and the team is still expanding rapidly. It is expected to reach thousands of people in the next six months.
While controlling the desert, the commissioned construction company built staff living quarters and a desert laboratory.
At present, the employees do not have a dormitory to live in, so they can only build temporary sheds for a transition. In addition, all materials can be guaranteed to be in place. It is a hard work to prevent the desert from being greened.
The plants planted include seabuckthorn, alpine goat grass, mulberry, desert persimmon, moso bamboo, Populus euphratica, Haloxylon, and Artemisia annua.
The characteristics of these plants are different, some are used to fix sand dunes and prevent soil erosion, some improve soil...
The main task of the first batch of employees is to carry out afforestation and greening treatment in this desert area to improve the local ecological environment and prevent desertification.
This is Mu Yang's meaning, as much as he can plant, his goal is to complete ten square kilometers of desert greening as soon as possible, and get systematic desert green planting seeds and cultivation technology rewards, so that desert governance can be accelerated in the future.
For this reason, regardless of the cost, Mu Yang also entrusted the construction of a hardened ground for the ground-effect aircraft to land or a water surface with a water depth of more than 3 meters.
Perhaps the fuel consumption of the Feilong ground-effect vehicle is about 100 yuan per kilometer, but this is calculated based on a full load of 240 tons, that is, the fuel consumption cost of every ten tons of cargo is 4 yuan, which is three or four times that of a freight car. It is not too expensive, after all, the efficiency is high, and the terrain is not limited, as long as there is a relatively flat ground or a deep water surface to land the aircraft.
At the same time, Xinghai Group will also use water-saving irrigation technology and solar power generation technology in greening work to reduce the consumption of local resources and actively explore new green development models.
This is not only conducive to the protection of the ecological environment, but also in line with the concept of sustainable development.
In addition, Xinghai Group also cooperates with local governments and enterprises to jointly promote desert governance and greening.
The entry of Xinghai Desert Greening Co., Ltd. will also provide local employment opportunities, drive local economic development, and achieve a win-win situation of economic and ecological benefits.
Xinghai Group's investment in desert control and greening has indeed been recognized by all walks of life, but the outside world can't understand why Xinghai Group spends so much energy on doing so. Although Zhou Chen held a media conference to explain it, they don't think it is So simple.
Indeed, the reward for greening ten square kilometers of desert, landscaping of millions of square kilometers for water diversion from east to west, planting economic plants, and laying out interstellar cities for the future, the last step is Mu Yang's final fantasy, which has never been revealed to the outside world.
August 11,
Yang Hai came back from a business trip and reported to Mu Yang and Zhou Chen the sales of computer chips, computers and Xiaobai systems.
"Since listing, the company has sold a total of 1.5 million desktop computers and 11.46 million notebook computers, of which the domestic share accounted for 75%;
In terms of computer bulk chips, a total of 34.5 million pieces were sold, and the market share of high-end chips reached 85%;
High-end phones of brands such as XXX, Pingguo, and Dell have been killed by us.
The sales of the Xiaobai system are also very good, with a total of 230 million units sold, and user satisfaction reached 99%.
It is normal for Xiaobai system to achieve this result. It is estimated that after reaching 500 million sets, the growth will be extremely slow, and it has an upper limit.
At present, the cumulative sales volume has reached 280 billion yuan. "Yang Hai said.
After listening to it, Mu Yang and Zhou Chen were very satisfied with the company's sales performance.
"Very good, the sales situation is better than expected, which shows that our products and services have been recognized by the market." Mu Yang nodded, "However, we still need to continue to work hard to improve the quality and competitiveness of our products and services. In order to maintain the leading position in the market, we will continue to suppress competitors such as Weisoft and Yingtel.”
International giants such as Weisoft and Yingtel have occupied the domestic market for so many years, and Mu Yang absolutely does not want these companies to continue to dominate the domestic market.
Thirty years in Hedong, thirty years in Hexi.
Zhou Chen also echoed: "Yes, we need to continue to innovate and improve, improve user experience, meet the needs of different users, and expand market share. I heard feedback from the customer center that due to the hot sales, our service cannot keep up. Insufficient production capacity, this is the problem we need to solve at present.
In terms of production capacity, I think the current situation will be maintained. New products will be at their peak for a period of time when they are just launched, and the market will soon be saturated. "
"It's fine, you can look at the arrangement." Mu Yang agreed, and he didn't have time to manage the specific details, "Mr. Yang, I'm not worried about the domestic market. It's mainly the foreign market. There will be some complicated factors mixed in. Really. Human power is impossible, so let’s give up, we don’t have to occupy.”
After hearing this, Yang Hai nodded in understanding, expressing that he would try his best to open up new international markets, and asked again:
"There is one more thing. The chip manufacturers of Pingtong and Yingtel have developed an 8nm chip process, which is expected to be mass-produced by the end of the year. When will we launch a 5nm chip?"
Xinghai Group's 8nm chip was launched in August 2014, and it has been three years since then.
In the past three years, the entire chip market has also undergone great changes. Xinghai Group's 5nm and 3nm processes have come out one after another, and even 5nm mass production equipment has been manufactured and can be mass-produced at any time, but it has not been launched on the market.
The gap between 8nm and 5nm chip technology is huge in terms of process size.
The smaller the process size, the higher the density of the chip, the lower the power consumption, and the better the performance.
In terms of the current process technology, the most obvious change of the 5nm process compared with the 8nm process is the increase in the number of transistors and the reduction in chip area.
The 5nm process adopts a tighter line width and interconnect structure design, which can integrate more transistors into a chip of the same size, thereby achieving higher computing performance.
At the same time, due to the increase in the number of transistors, the power consumption of 5nm chips is much lower than that of 8nm chips, so they have a wide range of application prospects in mobile devices, servers and other fields.
As for how much it has improved, each chip manufacturer is different. The transistor density of Xinghai Group's 5nm chip is more than twice that of 8nm, and the logic density is increased by 2.1 times.
Mu Yang thought for a while, and said: "From the current situation, even if the other party launches an 8nm chip with the same price and the same surface data, but because our chip structure is better and the energy consumption is lower, there is still a big gap. Competitive Advantage.
The launch of 5nm chips will definitely increase our costs a lot.
However, we have seized the high-end chip market in the past three years, and we are definitely not willing to be snatched back by competitors.
Let's do this, we must launch 5nm chips before the other party launches 8nm chips, and catch the other party by surprise, otherwise the other party will steal part of the market.
As for the price, we can keep the same price as we launched the 8nm in 2014, and continue to occupy the high-end chip market.
As for the price of the 8nm chip, if it is lowered to the cost price of the other party, it will directly cause the other party's 8nm chip to die.
Starlight 01 was originally priced at 600 yuan, but now it has dropped to 500 yuan.
As soon as the other party is listed, we will directly press down to 300 yuan to seize the low-end market.
I don't believe how long these companies can last. "
Three years ago, Mu Yang discussed and analyzed with the strategy department, and knew that these international chip giants could not be defeated at once, so they could only slowly consume their strength.
In the past three years, the opponent has laid off half of the staff, and the strength is not as good as before.
But a skinny camel is bigger than a horse, and its strength is still very strong, so don't relax.
If the price of Xinghai Group's Xingguang 01 is reduced to 300 yuan, the situation of these chip giants will be even worse, and it will be difficult to make money.
"Chairman, if we lower the price so much all at once, our friends and merchants will suffer huge losses if they have a lot of inventory." Yang Hai reminded.
Mu Yang thought for a while, and said: "You are right, we have started to reduce the production of 8nm chips here, to give friends and merchants a buffer time, and remind you, don't hoard chips without explaining the reason."
"The scalpers hoarding chips will be miserable." Zhou Chen said with a smile, "August is coming soon, I suggest that a two-month buffer time is almost the same, now we can start mass production of 5nm chips, and the National Day can announce 5nm chip information , let consumers know."
"Yes." Mu Yang agreed.
"Okay, I'll make a plan, there's nothing else to do." Yang Hai understood that the only ones who could get inside information were friends who purchased a lot, and the news might leak out, but it didn't matter.
The price reduction of 200 yuan will feel a loss to the consumers who have just bought it, and they may complain a little, but this can't be helped, Xinghai Group can't take everyone into consideration.
After discussing for a while, the three of them returned to their respective jobs.
They only discussed for an hour, and directly decided the direction of the global chip market, affecting hundreds of millions of consumers.
Those few international chip giants didn't know that a big net was already hanging over their heads.
