Zhangjiakou's high-precision processing equipment, or Nie Minhui helped Zhang Wenhao buy the domestic five-axis linkage machine tool, to say that the previous machining accuracy, even less than 0.5 microns, and the world's top military grade 0.01 microns, there is still a gap of dozens of times, and this set of equipment to Zhang Wenhao's hands, coupled with the continuous upgrading and change of Xiao Er, step by step self-upgrading, has reached the current 0.001 micron level.

The best way is to give a drawing accurate to 0.001 microns, let it actually perform a processing according to the drawing, and then measure what level of accuracy it can achieve through the final product.

These high-end scientists in the processing field are full of curiosity about this set of equipment, and they all hope to try to actually operate it, but Zhang Wenhao said that he can't do anything about it, because this set of equipment is all controlled by Xiao Er.

Director Liu also knew that bringing these scientists and experts over would not help him in any way, but when the high-level officials learned that Dongchen's high-precision machining center had world-leading ultra-high-precision machining capabilities, their first reaction was to quickly ask experts in the field of military industry to come over to observe and learn.

In response to the constant requests of those experts, Director Liu could only stand up, first refused and then appeased, and said: "Now this processing center is a high secret of the state, and our first task is to quickly and safely transport the equipment here to Jiangcheng, as for learning and observing." In addition, Comrade Xiao Zhang has promised us that this processing center will do its best for our military construction, and if there is a need for this set of processing equipment for the project at hand. can be submitted to the superior for approval. ”

An expert in shipbuilding 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 whole process?" ”

Director Liu glanced at Zhang Wenhao. said with a smile: "Let Comrade Xiao Zhang answer this request." ”

Zhang Wenhao smiled slightly and said, "Of course you can participate." ”

That being said. But Zhang Wenhao knew in his heart that when the time came, even if they participated, they could only provide preliminary data and drawings, and then stand aside to observe, all the processing processes were fully automated, and Xiao Er was fully responsible for the control of all machinery and mechanical arms, and no one needed to participate in it at all.

All the equipment is carefully dismantled and loaded into special wooden crates, which are then loaded into container trucks. The convoy drove back to Yanjing, but after entering Yanjing, the troops split into two routes.

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 Yanjingjun Airport in advance, and saw that all the equipment was loaded into an Il-76 transport plane. At one o'clock in the morning, five carefully selected armed police officers and special police officers followed the two crew members to board the plane, and the plane took off directly from the airport without any delay and flew into the sky.

Zhang Wenhao did not delay much and returned to Yanjing Airport with Secretary Liu. The two took a private jet and flew to Jiangcheng, after the plane took off, Director Liu received a phone call, and then, hung up the phone and said to Zhang Wenhao: "Jiangcheng has been prepared by the armed police and special police, and the plane landing will be directly pushed into the hangar requisitioned by the military, and then all the equipment will be transferred to the car transportation in the hangar, and after we get off the plane, we will go to the industrial base of the high-tech zone with them, and before dawn, all the equipment will be transported into the prepared plant." ”

Zhang Wenhao nodded and said, "This shouldn't be a big problem." ”

Director Liu said with a smile: "The problem is definitely not, and now there is no leakage of any rumors, the participating armed police special police, not only carefully selected, but also without any disclosure, they do not know what the items involved in the transport are, in addition, these experts you don't have to worry, each of them in their respective fields, have mastered very important national defense technology, and the reliability has been tested." ”…,

Zhang Wenhao smiled: "I'm not worried about this, as long as the process goes well, the reason why I didn't disclose it to you before is that I think this kind of thing is a bit shocking, and now even if I tell you, I must not leak it out, otherwise, I'm afraid it won't be peaceful." ”

Director Liu nodded in agreement and said, "By the way, the military has a commission, I don't know if you can help?" ”

Zhang Wenhao said: "You say." ”

Director Liu said with a smile: "That's the case, before Zhongchen materials have cooperated with the state, the new aluminum alloy, steel alloy two materials, except for Dongchen's own use, all the others are purchased by the state, we have also begun to apply this material to our national defense science and technology products, before we have always been our own processing and production, but now you have better processing equipment here, so, the military wants to give you a commissioned order, the military put forward a 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 give specific plans and parameters, drawings and other requirements." ”

Director Liu asked with a smile: "Now, our biggest and most anxious demand is the aero engine, our self-made Taihang series fighter engine, the biggest problem is that the processing accuracy is not enough, many parts are plagued by this problem, the military means, these parts are handed over to Dongchen to process and produce." ”

Zhang Wenhao frowned slightly, and said: "In the case of relatively low technology content, no matter how high-end the manufacturing process is, it will not play a qualitative change, even if all the components are manufactured by Dongchen, and the technology used is still the technology of the Taihang series of engines, then the engine will not be stronger than the previous Taihang, and the limited benefit is that the loss is reduced and the service life is improved." ”

Director Liu smiled helplessly and said: "There is no way to do this, but after all, this is our own best engine now, even if it is imitation, we can only get access to Russian aircraft engines, and it is not the best in their hands, as for the American military engine, we have very few opportunities to even see it with our own eyes, and there is no way to imitate it." ”

Zhang Wenhao hesitated for a moment. opened his mouth and said: "I can accept this commission, but the military had better be mentally prepared, even if Dongchen is in charge of processing, the improvement will not be too big." ”

Director Liu nodded and said: "In fact, even if it can only improve the reliability and service life of machinery, it is a major breakthrough." ”

Zhang Wenhao was thinking in his heart when he would ask the senior management for a ready-made engine production line, but Zhang Wenhao was not interested in directly producing military aircraft engines. Instead, priority is given to civilian engines, the former is too sensitive, and it is easy to push Dongchen to the forefront at once. The latter is relatively peaceful, and the market space is also large.

Zhang Wenhao's private business jet landed at Jiangcheng Airport, and at this time. A large hangar of Airbus A330 has been requisitioned by the armed police and martial law, Zhang Wenhao's private jet was pushed to the hangar next door, as soon as the plane got off the plane, Zhang Wenhao and Officer Liu hurried to the hangar next door, after making sure that all the equipment had been loaded into the car, the two also got on 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 fighting here day and night. Therefore, no one was surprised that there was an extra convoy, and after these container trucks entered the industrial base, they drove directly to the customized factory that Zhang Wenhao had already prepared.

The equipment was fully transported to the new plant before dawn and a specialist was in charge of the installation. Zhang Wenhao is not worried about this, five-axis linkage machine tools are not a rare thing in China, and the real strength of this equipment is not seen by looking. …,

It took a whole day to complete the erection of the equipment, and Officer Liu returned to Yanjing to report the situation to the high-level and assist the General Staff in summarizing all the processing needs in the field of military industry. And set a time priority based on priorities.

At this time, Zhang Wenhao had the opportunity to bury his head in his own affairs.

The high-precision machining center is once again in working condition, this time with an engine to be installed on the SC1, a 6.0-liter, V-shaped 12-cylinder metal monster.

In addition to the engine, Zhang Wenhao also intends to create a high-performance, technology-leading 10-speed dual-clutch transmission, this gearbox, has become a perfect match for 6.0 liters and above displacement engine, in other words, only such a high-end gearbox, can be matched with more than 1,300 horsepower super engine, and after the combination of the two, what is presented is an amazing power output, torque output, and the rapid conversion and coordination of speed and power.

There is no truly mature 10-speed gearbox in today's sedan segment, and although BMW had already built the most eye-catching 10-speed gearbox several years ago, it was still not used in production cars a few years later.

The core reason is that the 10-speed gearbox manufactured by today's technology is too huge!

Huge, it makes its volume much larger than the general 6-speed or even 8-speed gearbox, big also means heavy, generally need to apply 10-speed gearbox cars, are supercars such as the pursuit of speed as the limit of the big killer, and the power of the big killer is high, but it is to be applied to the speed, it can not have too much weight, otherwise, it is counterproductive.

In addition to the large size and heavy weight, the immature technology is also the fundamental reason why the 10-speed gearbox cannot really enter the practical application field, coupled with the more complex construction, the number of parts almost doubled, making this transmission the probability of failure high, maintenance difficult and unusually high.

Combined with the above factors, BMW's 10-speed gearbox has become a gimmick in a short period of time, and other brands have also given up the process of developing a 10-speed gearbox from the actual situation.

Zhang Wenhao will come up with the 10-speed gearbox technology, is the 10-speed gearbox, the most mature and outstanding set of technology, the total volume and weight, basically similar to the current 8-speed gearbox, and its performance, is very outstanding, even in the next 20 years, no one can compare.

And this gearbox will use Dongchen's unique special steel alloy, this special steel alloy, has not appeared in 30 years, so once this gearbox rolls off the assembly line, its performance is better than its blueprint. That is, the gearbox in thirty years is better.

For SC1, a top supercar positioning car, the four-wheel drive system will never be used, only the rear drive is the most suitable for the supercar, and Zhang Wenhao in the power layout, also used the rear-mounted engine compartment commonly used in supercars, and the power mode is rear-wheel drive.

Since the SC1 will run at a top speed of more than 500 km, so. It is no longer suitable for conventional braking systems, and the brake discs are made of Dongchen special steel alloy with 45 holes evenly opened on it. It is used to give the brake disc better heat dissipation ability during extreme braking.

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 copes with braking at extreme speeds, brake pads and brake discs can easily cope with thousands of degrees of high temperatures, but its stability will not change in any way, and the metal performance is stable.

However, the braking system made of special materials is still not enough to make the car stand still quickly at top speed, so there is a hidden rear wing behind the car. The rear wing is in an adducted state at 200 km/h, and when the original speed exceeds 200 km/h, the driving computer will automatically release the rear wing. …,

The released rear wing can enhance the stability of the car at high speeds on the one hand, and on the other hand. It will also provide better aerodynamics to the car, and the spoiler will generate more downforce, so that the car can have good grip at high speeds.

The trip computer uses the most accurate calculation mode, so it rises every kilometer per hour at a speed. There will be a slight adjustment that is not visible to the naked eye, so as to make the aerodynamics of the rear wing more in line with the new speed requirements.

On both sides of the body, behind the doors, there are two side wings that are no more than six centimeters wide, and the side wings are the killer features of the SC1 to stabilize the body at ultra-high speeds!

When the flanks are in the state of 400 kilometers per hour, they are all retracted, and only when the speed reaches more than 400 kilometers per hour, the flanks will be opened, and they will also be handed over to the driving computer to accurately control, providing the car with stronger aerodynamics, better downforce and grip.

The purpose of the rear wing and side wing is not only to stabilize the running state of the car in the state of extreme speed, but also to activate the rear wing and side wing when the car brakes urgently, so that it can participate in the braking, so that the car can change from top speed to stationary faster and more stable.

Aerodynamics is a very interesting thing, if there is a spoiler at the rear of the car, which is low in the front and high in the rear, then when the air in the top speed state flows through the spoiler, at the end of the spoiler, because the tail is higher, it will move upwards and generate enough downforce.

The speed of civil aviation take-off does not exceed 300 kilometers, and this speed, the vast majority of supercars can be achieved as long as there is a straight road with sufficient conditions, but unlike airplanes, the airplane at this speed, aerodynamic force gives it enough lifting force, while the car, at this speed, aerodynamic force gives it enough downforce to ensure that it is close to the ground.

When the spoiler changes the angle and increases the area of its direct contact with the air, the air will bring great resistance to the body because of the larger contact area, and the speed will drop in the face of great resistance.

If you want to reach a speed of more than 500 kilometers, ordinary car tires can not be controlled at all, I am afraid that before this speed, the temperature of the tires has reached an extremely dangerous point, I am afraid that in that state, the tires that are usually very strong will become like a balloon that is full of balloons, and may explode at any time.

Zhang Wenhao did not have time to produce his own special tires, so he decided to purchase them from Michelin.

Michelin has created a unique tire for Bugatti, which uses Michelin's highest-end, even high-end technology that is no longer suitable for civilian vehicles, and also uses PA-X explosion-proof technology, which meets the requirements of SC1, but the price is surprisingly expensive, the price of a single tire is more than 20,000 pounds, and the price of four tires combined is close to 100,000 pounds.

However, the top supercar is a thing, there is no need to consider the cost performance, it is aimed at consumer groups, that is, those who have so much money that they don't know where to spend it, the more expensive it is, the more he likes it, 100,000 pounds of tires, normal use, every 5,000 kilometers to change it, but this is not Zhang Wenhao's problem, the price of SC1 will inevitably exceed 50 million yuan, and it is already very good to sell 50 cars 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 thought that Bugatti is a good-looking car, in terms of appearance, it is far less first-class than Ferrari and Maserati and Aston Martin and has its own unique taste, while the SC1 model is absolutely domineering to suffocation.

The height of the vehicle is similar to that of the Lamborghini LP700, the body is about ten centimeters wider than the LP700, and the streamlined design of the vehicle has gone beyond the contours of modern aesthetics.

The tail design has only two exhaust pipes, the tailpipe is two symmetrical flat triangles, and the three corners are designed with rounded arcs to adapt to the 6.0 engine.

Zhang Wenhao has done C3C, which is definitely the all-round all-round model that can be called the king of off-road comprehensive, he knows that once there is a peak product comes out, how powerful is the praise and respect given by global consumers, so this SC1 must stand on the top of the world that is absolutely unshakable!
