wThis set of high-precision processing equipment in Zhangjiakou is the domestic five-axis machine tool that Nie Minhui helped Zhang Wenhao purchase. The previous processing accuracy did not even meet the 05 micron requirement, which is comparable to the world's top military-grade 001 micron.
There is still a gap of dozens of times, but after this set of equipment came into Zhang Wenhao's hands, coupled with the waiter's continuous upgrades and changes, he upgraded himself step by step, and it actually reached the current 0001 micron level.
For high-precision processing equipment like this, it is completely impossible to draw any conclusions just by looking at it with the naked eye. The best way is to give a drawing accurate to 0001 microns, let it actually perform processing according to the drawing, and then pass the final
of the finished product to measure the level of accuracy it can achieve.
These high-end scientists in the field of processing were full of curiosity about this equipment, and they all expressed their hope to try to operate it in practice, but Zhang Wenhao expressed his inability to do so, because this equipment is all controlled by the waiter.
Director Liu also knew that bringing these scientists and experts over would not be a hindrance and would not be of any help. It was just that when the senior management learned that Dongchen’s high-precision machining center had world-leading ultra-high-precision machining capabilities, their first reaction was
Just let experts in the military industry come over to observe and learn.
In response to the constant requests from those experts, Director Liu could only step forward, first refusing and then appeasing him, and said: "This machining center is a highly confidential matter of the country. Our first priority is to transport the equipment here quickly and safely."
When we go to Jiangcheng, as for learning and observing, there will be many opportunities in the future. In addition, Comrade Xiao Zhang has promised us that this processing center will do its best for our military construction. If the project at hand requires the use of this set of processing equipment
You can report it to your superiors for approval."
An expert in ship manufacturing couldn't help but ask: "If our project is approved by the state and high-precision processing and manufacturing is carried out in Jiangcheng, can our people participate in the entire process?"
Officer Liu glanced at Zhang Wenhao and said with a smile: "Let Comrade Zhang answer this request."
Zhang Wenhao smiled slightly and said, "Of course you can participate."
Although he said this, Zhang Wenhao knew in his heart that even if they participate, they can only provide preliminary data and drawings, and then stand aside and observe. All processing processes are fully automated and are handled by waiters.
He is fully responsible for the control of all machines and robotic arms, without anyone needing to participate.
All the equipment began to be carefully disassembled and packed into special wooden boxes, and then all loaded into container trucks. The convoy drove back to Yanjing, but after entering Yanjing, the troops split into two groups.
A carload of experts who came to make soy sauce went directly back to the city, while Zhang Wenhao and Liu Gan followed the transport team to Yanjing Military Airport and saw all the equipment being loaded into an IL-76 transport plane. At one o'clock in the morning, five elites
Carefully selected armed police special police followed the two crew members onto the plane. The plane took off directly from the airport without any delay and soared into the sky.
Zhang Wenhao did not delay much and returned to Yanjing Airport with Director Liu. The two took a private plane and flew to Jiangcheng. After the plane took off, Director Liu received a phone call. Then, he hung up the phone and said to Zhang Wenhao: "Jiangcheng
There are armed police special police there ready. When the plane lands, it will be pushed directly into the hangar requisitioned by the military. Then all the equipment will be transferred to the car for transportation in the hangar. After we get off the plane, we will go to the high-tech zone with them.
At the industrial base, before dawn, all equipment was transported into the prepared factory building."
Zhang Wenhao nodded and said, "This shouldn't be a big problem."
Director Liu smiled and said: "The problem is that there is definitely not, and there is no news leaked now. The armed police special police who participated were not only carefully selected, but they also did not disclose anything. They did not know what the items were being transported. In addition,
You don’t have to worry about these experts, each of them masters very important national defense technology in their respective fields, and their reliability has been tested.”
Zhang Wenhao smiled and said: "I'm not worried about this, as long as the process goes smoothly. The reason why I didn't disclose it to you before was because I thought this kind of thing was a bit shocking. Now even if I tell you, it must not be leaked. Otherwise, I'm afraid it won't be possible."
Peaceful."
Officer Liu nodded in agreement and said, "By the way, the military has a commission. I wonder if you can help?"
Zhang Wenhao said: "You say."
Officer Liu smiled and said: "That's right. Zhongchen Materials has cooperated with the state before. Except for Dongchen's own use of these two materials, new aluminum alloys and steel alloys, all other materials are purchased by the state. We have also begun to purchase them.
This material is used in our national defense technology products. We have been processing and producing it ourselves before. However, now you have better processing equipment here, so the military wants to give you a commission order and the military will make the request.
, Dongchen is responsible for processing and production."
Zhang Wenhao did not hesitate at all and said with a smile: "There is no problem with this. Just let the military provide specific plans, parameters, drawings and other requirements."
Officer Liu asked with a smile: "Looking at it now, our biggest and most urgent demand is aviation engines. The biggest problem with our self-made Taihang series fighter engines is that the processing accuracy is not enough. Many parts are troubled by this problem.
, the military intends to hand over these parts to Dongchen for processing and production."
Zhang Wenhao frowned slightly and said: "With relatively low technological content, no matter how high-end the manufacturing process is, there will be no qualitative change. Even if all components are manufactured by Dongchen, the technology used is still the Taihang series engine.
With our own technology, the engine we build will not be any better than the previous Taihang. The limited benefits are that the loss is reduced and the service life is improved."
Officer Liu smiled helplessly and said: "There is nothing we can do about this, but after all, this is our best engine now. Even if we imitate it, we can only have access to Russian aircraft engines, and it is not the best engine they have.
Okay, as for American military engines, we even have very few opportunities to see them with our own eyes, and there is no way to imitate them."
Zhang Wenhao hesitated for a moment and then said: "I can accept this commission, but the military had better be mentally prepared. Even if Dongchen is responsible for processing, the improvement will not be too big."
Officer Liu nodded and said: "In fact, even if it can only improve the reliability and service life of machinery, it is still a major breakthrough."
Zhang Wenhao was thinking about when he would ask the senior management for a ready-made engine production line. However, Zhang Wenhao was not interested in directly producing military aircraft engines. Instead, he gave priority to civilian engines. The former was too sensitive and could easily push Dongchen to the forefront.
.The latter is relatively peaceful and has a large market space.
Zhang Wenhao's private business jet landed at Jiangcheng Airport. At this time, a large Airbus A330 hangar had been requisitioned by the armed police special police and was under martial law. Zhang Wenhao's private jet was pushed to the hangar next door. After getting off the plane, Zhang Wenhao and Officer Liu
They hurried to the hangar next door. After making sure that all the equipment had been loaded into the car, the two got into an armed police off-road vehicle and drove directly to the high-tech zone.
During this time, Dongchen's industrial base in the High-tech Zone was busy, with large vehicles constantly coming in and out, and a large number of people working here day and night. Therefore, no one was surprised by the addition of this fleet, and these container trucks entered
After the industrial base, they drove directly to the customized factory that Zhang Wenhao had already prepared.
All the equipment had been transported into the new factory before dawn, and professionals began to be responsible for installation. Zhang Wenhao was not worried about this. Five-axis machine tools are no longer rare in China. The real strength of this equipment is also
You can't tell by looking at it.
It took a whole day to set up the equipment. Officer Liu returned to Yanjing to report the situation to the senior management, and will assist the General Staff in summarizing all processing needs in the military industry. He will also develop a time priority based on priorities.
At this time, Zhang Wenhao had the opportunity to immerse himself in doing his own thing.
The high-precision machining center began to work again. The product this time is the engine that will be configured on the SC1, a twelve-cylinder metal monster with a displacement of 60 liters and a vertical arrangement.
In addition to the engine, Zhang Wenhao also intends to create a 10-speed dual-clutch gearbox with excellent performance and leading technology. This gearbox will become a perfect match for engines with a displacement of 60 liters and above. In other words, it is the only high-end gearbox like this.
Only a gearbox can be paired with a super engine with more than 1,300 horsepower, and when the two are combined, what they present is amazing power output, torque output, and rapid conversion and coordination of speed and force.
There is not yet a truly mature 10-speed gearbox in the car field today. Although BMW had produced a very eye-catching 10-speed gearbox several years ago, this gearbox was not available in a few years.
After that, it was still not applied to mass-produced cars.
The core reason is that the 10-speed gearbox manufactured with today's technology is too large!
It is huge, which makes its volume much larger than the ordinary 6-speed or even 8-speed gearboxes. Big means heavy. Generally, cars that need to use 10-speed gearboxes are supercars that pursue speed as their limit.
A big killer, and although the power of a big killer is high, it must all be used for speed. It cannot have too much weight, otherwise it will be counterproductive.
In addition to its large size and weight, immature technology is also the fundamental reason why the 10-speed gearbox cannot really enter the field of practical application. In addition, the structure is more complex and the number of parts has almost doubled, making this kind of gearbox
The probability of failure is high, maintenance is difficult and the cost is unusually high.
Based on the above factors, BMW's 10-speed gearbox has become a gimmick in a short period of time. Other brands have also given up the process of developing 10-speed gearboxes based on reality. Advanced and widely used multi-speed gearboxes,
The highest speed is basically maintained at 8 speeds, because the technology of 8-speed gearboxes is relatively mature.
The 10-speed gearbox technology that Zhang Wenhao will come up with is the most mature and outstanding set of technologies among 10-speed gearboxes. The total volume and weight are basically similar to the current 8-speed gearbox, but its performance is
It is so outstanding that no one will be able to compare with it even within the next twenty years.
This gearbox will use Dongchen's unique special steel alloy. This special steel alloy has not appeared thirty years later. Therefore, once this gearbox comes off the production line, its performance will be better than its blueprint.
That means the gearbox will be better thirty years later.
For a car that is positioned as a top supercar like the sc1, a four-wheel drive system will never be used. Only rear drive is most suitable for supercars. In terms of power layout, Zhang Wenhao also uses a rear engine compartment commonly used in supercars.
, the power mode is rear-mounted and rear-wheel drive.
Since sc1 will run at a top speed of more than 500 kilometers, it is no longer suitable for conventional braking systems. The brake disc is made of Dongchen special steel alloy, and has forty-five holes evenly opened on it. It is used to brake at extreme speeds.
This gives the brake disc better heat dissipation capability.
In addition, the brake disc does not use the internationally popular ceramic brake pads, but still uses Dongchen's special steel alloy. It provides higher strength and high temperature resistance, and has stronger wear resistance, easily coping with extreme speeds.
When braking under normal conditions, the brake pads and brake discs can easily cope with high temperatures of thousands of degrees, but their stability will not change in any way, and the metal properties are stable.
And just the braking system made of special materials is still not enough to stop the car quickly at top speed. Therefore, there is a hidden rear wing behind the car. This rear wing is at a speed of 200 kilometers per hour.
In the retracted state, when the vehicle speed exceeds 200 kilometers, the trip computer will automatically release the rear wing.
The released rear wing can, on the one hand, enhance the stability of the car at high speeds. On the other hand, it will also provide the car with better aerodynamics, and the spoiler will generate greater downforce, allowing the car to fly at high speeds.
, good grip.
Since the trip computer adopts the most accurate calculation mode, every time the speed increases by one kilometer per hour, it will make a slight adjustment that is invisible to the naked eye to make the aerodynamics of the rear wing more in line with the new speed requirements.
On both sides of the car body, behind the door, there are two side wings with a width of no more than six centimeters. The side wings are SC1's trump card for stabilizing the car body when running at ultra-high speed!
When the speed is 400 kilometers per hour, the side wings are all retracted. Only when the vehicle speed reaches more than 400 kilometers per hour, which is a terrifying top speed, the side wings will be opened, and they will also be accurately controlled by the driving computer.
Provides the car with stronger aerodynamics, better downforce and grip.
The purpose of the rear wing and side wings is not only to stabilize the running state of the car at top speed. When the car brakes urgently, the tail wing and side wings will be activated to participate in the braking, allowing the car to change from top speed to speed faster and more stably.
Become still.
Aerodynamics is a very interesting thing. If there is a spoiler at the rear of the car that is low in the front and high in the rear, then when the air at top speed flows through the spoiler, at the end of the spoiler, it will
Its tail is higher and moves upward, while generating sufficient downforce.
The speed of civil aviation when taking off does not exceed 300 kilometers, and this speed can be reached by most supercars as long as there is a straight road with sufficient conditions. However, unlike airplanes, at this speed, the aerodynamic force of airplanes
It has enough lifting force, and the car, at this speed, the aerodynamic force gives it enough downforce to ensure that it sticks to the ground.
When the spoiler changes its angle and increases the area of direct contact with the air, the air will bring great resistance to the car body due to the larger contact area. In the face of great resistance, the vehicle speed will decrease.
Paired with a braking system, it is easier for a car to stop quickly at extreme speeds.
If you want to reach a speed of more than 500 kilometers, ordinary car tires cannot control it at all. I am afraid that the temperature of the tires has reached an extremely dangerous level before reaching this speed. I am afraid that in that state, they are still extremely strong.
Tires will become like an inflated balloon and may explode at any time.
Zhang Wenhao did not have time to produce special tires by himself, so he decided to purchase them from Michelin.
Michelin has specially designed a unique tire for Bugatti. This tire uses Michelin's most high-end technology, which is even so high-end that it is no longer suitable for the civilian car field. It also uses PA-X explosion-proof technology, which meets the requirements of SC1, but the price is
It is surprisingly expensive. A single tire costs more than 20,000 pounds, and the total price of four tires is close to 100,000 pounds.
However, there is no need to consider cost-effectiveness for something like a top-notch supercar. The consumer group it faces is those people who have so much money that they don’t know where to spend it. The more expensive it is, the more they like it. A tire worth 100,000 pounds is normal.
If used, it needs to be replaced every five thousand kilometers, but this is not Zhang Wenhao's problem. The price of sc1 will definitely exceed 50 million yuan, and it is already very good to sell fifty units a year.
However, for Zhang Wenhao and Dongchen, the significance of sc1 is not sales and profits, but its unparalleled speed.
Zhang Wenhao has never felt that Bugatti is a good-looking car. In terms of appearance, it is far inferior to Ferrari, Maserati and Aston Martin. It has its own unique flavor, but the sc1 model is absolutely domineering and breathtaking.
.
The height of the vehicle is similar to that of the Lamborghini LP700, and the body width is about ten centimeters wider than the LP700. The streamlined design of the vehicle has exceeded the outline of modern aesthetics. No matter from which angle it is viewed, this vehicle has no visual Achilles' heel.
The tail design has only two exhaust pipes in the whole vehicle. The tail throat is two symmetrical flat triangles, and the three corners adopt an arc transition design to adapt to the 60-inch engine.
Zhang Wenhao has worked on the C3C, a comprehensive all-round model that can definitely be called the king of off-road comprehensives. He knows how powerful the praise and admiration given by consumers around the world will be once a top product comes out. Therefore, this SC1 must be
Standing on the top of the world that is absolutely unshakable! Welcome to your support, which is my greatest motivation.m
