The power system used 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, which generates downward airflow through high-speed rotation, thereby generating vertical downward lift, thereby achieving vertical take-off, landing and hovering.

Therefore, lift fans are widely used in military, civilian and scientific research fields.

On fighter jets, a lift fan is used to balance the power of the rear turbofan engine, such as the F-35B and Harrier fighter jets.

Of course, only the displacement nozzle can achieve vertical downward thrust. 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 Feilong ground-effect aircraft is required to be equipped with four 02J afterburning turbofan engines and four lift fans. The full thrust requirement of each lift fan is 15 tons.

The manufacture and design of a lift fan requires consideration of many factors, such as the material, shape, size, etc. of the rotating propeller or blades.

The most difficult thing to manufacture is of course the blades. The mass of the blades of a lift fan accounts for most of the weight.

If a single blade is heavy, the rotation speed cannot be fast, and a huge horizontal force is generated, which wears out too quickly for the rotating shaft and is unstable.

Therefore, the blade material is required to be low-density, such as titanium alloy or aluminum alloy.

Low density alone is not enough. It is best to have a hollow structure inside the blade to reduce weight.

Xinghai Group has metal 3D additive technology, making blades very easy to manufacture.

For Xinghai Group, how to increase the lift fan thrust ratio is important.

Mu Yang came to the laboratory that studies lift fans. The project leader saw the chairman coming to inspect and helped him introduce the project results.

"What is the final thrust ratio?"

"A single lift fan weighs 4.3 tons, has a full thrust of 15.5 tons, and a thrust ratio of 3.60."

"Okay, not bad, what is the speed at full thrust?" Mu Yang praised, this thrust ratio is extremely high, and it rarely reaches more than 3. For example, the lift fan thrust ratio of the F-35B fighter jet is 2.

This is not a turbofan engine after all.

Thrust has a great relationship with rotational speed, blade structure and duct diameter, while thrust ratio has a great relationship with the weight of the lift fan. Xinghai Group's lift fan can have such a high thrust ratio mainly because the blade mass is very light, but the structure

The strength is not bad.

"14,500 per minute."

Mu Yang nodded. In fact, lift fans are not that impressive. If it were not for vertical takeoff and landing in a small space, or for hovering in the air for observation or search tasks, the speed and carrying capacity would not be as good as those without lift fans.

The lift fan increases the structural complexity and weight of the aircraft, and it does not operate when flying at high speeds.

Like the F35B, when lifting vertically, you need to open the top ventilation cover of the lift fan. When you can fly horizontally, close the cover and stop the lift fan at the same time.

Similarly, after Muyang's ground-effect aircraft starts flying, the lift fan must be turned off.

If it is not for vertical take-off, taxiing for take-off and landing is also possible. Remove the lift fan and save nearly 20 tons of gravity.

But it has great benefits, as the lifting and landing can be controlled very well, and it is safer at the same time.

This ground-effect aircraft project has a total of three cores, the lift fan, the 02J engine and the balance system.

At present, the three cores have been completed and assembly has begun. If everything goes well, it is expected that the assembly and test flight will be completed in about four months.

Wingspan: 85-90 meters, aircraft length: 80-90 meters, aircraft height: 15-17 meters.

The Xinghai Group headquarters base cannot carry out large-scale assembly, and it is not suitable for test takeoff after assembly.

The large assembly plant is located in the rocket manufacturing factory in Yangfu District, where there is enough workshop space and open space. It is also very close to the Qianjiang River and can then be driven to the sea for high-speed testing.

The space of the rocket base is larger, but transportation there is a bit troublesome.

However, Mu Yang still suggested communicating with the relevant departments first. After all, ground-effect aircraft are not simple. It will be troublesome if test flights are not allowed after the assembly is completed. Then they can only be disassembled and put into the rocket base for assembly and then tested in the sea.

When Mu Yang reported the news to someone, the other person was very shocked.

"You have 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, I left with satisfaction.

After another day, I got a reply: The surrounding area will be controlled by then, 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 takes place, there is no way to hide from the outside world that this big thing, the ground-effect aircraft, will not be dangerous when operating at low speed on the Qianjiang River.

Mu Yang was very satisfied with the response from the relevant departments, and then issued an order: Starting today, the ground effect aircraft will begin emergency assembly.

August 10,

Desert greening was officially launched, and the treatment location is in the desert area fifty kilometers northwest of Zhongwei City.

This area is also where the ant forest will be managed in the future, covering an area of ​​about 60,000 square kilometers.

When 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, and is expected to reach thousands of employees in the next six months.

While the desert is being managed, a construction company was commissioned to build employee dormitories and a desert laboratory.

At present, employees do not have dormitories to live in, so they can only build temporary sheds for transition. In addition, all materials are ensured to be in place. Preventing the desert from becoming green is a hard-working job.

The plants planted include sea buckthorn, alpine goat grass, mulberry, desert persimmon, moso bamboo, Populus euphratica, Haloxylon ammodendron, wormwood, etc.

These plants have different functions and characteristics. Some are used to stabilize sand dunes and prevent soil erosion, and some are used to improve soil...

The main task of the first batch of employees is to carry out afforestation and greening management in this desert area to improve the local ecological environment and prevent desertification.

This is what Mu Yang means. He can plant as much as he can. His goal is to complete the greening of ten square kilometers of desert as soon as possible and obtain systematic rewards for desert greening seeds and cultivation technology, so that desert control can be accelerated in the future.

To this end, regardless of the cost, Muyang also commissioned the construction of hardened ground or water with a water depth of more than 3 meters for the ground-effect aircraft to land.

Perhaps the fuel consumption of the Feilong ground-effect aircraft 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 truck. This comparison

It’s not expensive, after all, it’s highly efficient, and it’s not limited to terrain, as long as you have a relatively flat ground or deep water 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 protecting 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 control and greening work.

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 does not understand why Xinghai Group spends so much energy on this. Although Zhou Chen held a media conference to explain it, they feel that it is not the case.

So simple.

Indeed, ten square kilometers of desert greening will be rewarded, and the east-west water diversion and storage plan will green one million square kilometers, planting economic plants, and laying out an interstellar city 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 returned from a business trip and reported to Mu Yang and Zhou Chen on the sales of computer chips, computers and Xiaobai systems.

“Since its listing, the company has sold a total of 1.5 million desktop computers and 11.46 million laptop computers, of which the domestic share accounts 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%;

We have killed all the high-end mobile phones from brands such as Xixiang, Pingguo, and Dell.

The sales of the Xiaobai system are also very good. A total of 230 million units have been sold, and the user satisfaction rate has reached 99%.

It is normal for novice systems to achieve this result. It is estimated that the growth will be extremely slow after reaching 500 million units. It has an upper limit.

The current cumulative sales have reached 280 billion yuan." Yang Hai said.

After listening to this, Mu Yang and Zhou Chen were both very satisfied with the company's sales performance.

"Very good, the sales are 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 Wesoft and Yingtel."

International giants such as Wesoft and Yingtel have occupied the domestic market for so many years, and Muyang definitely 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 booming sales, our services cannot keep up.

Insufficient production capacity is a problem we currently need to solve.

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 just after they are launched, and the market will soon be saturated."

"That's okay, you just have to look at the arrangements." Mu Yang agreed. 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 involved. In fact,

If you can't do it with human power, then give up, we don't necessarily want to occupy it."

After hearing this, Yang Hai nodded and understood, saying that he would try his best to open up new international markets, and asked:

"One more thing, Pengtong, Yingtel chip manufacturer has developed an 8nm chip process and 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, three years ago.

In the past three years, the entire chip market has also undergone great changes. Xinghai Group's 5nm and 3nm processes have been launched one after another. Even the 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 processes 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.
