Chapter 326 special exchange

The perfect test of two ten one blade large side inclined propellers made the military immediately make up its mind to order advanced submarine propellers from Dongchen in large quantities. The submarines in China are divided into two categories: conventional submarines and nuclear submarines. The types of submarines at various levels are more complex and the sizes of tons are different. The military hopes that Dongchen can design and manufacture different submarines according to their different levels With the proportion of three propellers for every two submarines of the same type, Dongchen received orders from the military for up to 120 propellers.

Fortunately, the military has not been greedy and rash, trying to complete the submarine innovation and progress in the shortest time. They have made a contract for Dongchen for up to two years. In addition to the ten largest size of the eleven blade large side inclined propeller, the other propeller sizes are relatively small, so it is easier to process and manufacture. For Dongchen, it's easy to build it in a timely manner The consumption will not exceed one and a half years. During this period, the high-precision machining center must meet the needs of Dongchen group.

State owned high-end industrial processing enterprises, such as the military and aerospace fields, are waiting for one day to be able to rank in the Dongchen high-precision processing center and rebuild the core parts with high precision, but Dongchen is unable to undertake more national orders. The submarine propeller list alone has taken up a lot of work, with high precision After all, there is only one processing center, and Dongchen has to meet its own needs. Therefore, the senior leaders are worried about this. Shortly after Zhang Yunfeng returned to Jiangcheng, director Liu came back and brought a high-level suggestion. That is, Dongchen, funded by the state, helped the state build a new high-precision processing center. In this way, the state-owned The cutting-edge enterprises can make use of the state-owned processing center, and also can better alleviate the urgent needs of the current cutting-edge enterprises.

Zhang Yunfeng understands that it is better to teach people to fish than to teach people to fish. However, Dongchen's high-precision processing technology is a universal key to open up high-end industrial manufacturing. This technology is not only important for an enterprise, but also extremely important and core for a country. The country tries to let Zhang Yunfeng take this technology out, which is also Zhang Yunfeng A sufficient exchange chip has been prepared.

Director Liu, at the moment of Zhang Yunfeng's consideration, threw out a heavy bomb and said: "the senior leadership means that this time, after Dongchen established the high-precision machining center, all the engine production lines of COMAC will be handed over to Dongchen. Haven't you always thought of doing the aviation industry? The foundation of COMAC can be said to be the best in the field of civil aviation in our country. "

Zhang Yunfeng was happy and asked with a smile, "give me the engine production line of COMAC? What about COMAC's own big plane project? "

Director Liu smiled helplessly and said: "COMAC's own project has little practical significance. COMAC's own large aircraft has poor sales volume, poor performance, cost performance and other advantages. In a word, it can't compare with Airbus and Boeing. In the beginning, COMAC launched the project to solve domestic demand, but the current Airlines won't do this either What a smooth flow of people, the previous empty check was quite big, but after COMAC's big aircraft came off the line, it suffered a large number of cancellations. Now the total number of effective orders is less than 30. The profits of these 30 aircraft are far from enough to make up for the research and development costs of the whole project. Moreover, the buyer refused to use the domestic turbofan engine for the remaining orders, and COMAC has not done so Therefore, the whole engine production line has basically entered the idle state. "

Zhang Yunfeng nodded and asked curiously, "is COMAC in the production of those 30 orders now?"

Liu said: "the deposit for these 30 orders has been paid, but it is said that the buyer has the intention to unsubscribe. Now, Airbus is negotiating with several buyers in private. If it unsubscribes and orders Airbus A320, Airbus will give each aircraft a $5 million discount."

Zhang Yunfeng was surprised and asked, "what is the trouble with Airbus? They are such a big enterprise, shouldn't they care about the orders of the thirty? "

Liu Ganshi shrugged his shoulders and said: "you may not know much about this. COMAC's project has a direct conflict with Airbus A320 and Boeing 737. If COMAC really gets on the horse, and if more than 200 orders before are retained, COMAC will usher in a huge leap. I dare not say it abroad, but at home, the sales volume of Airbus and Boeing at the same level will be large Affected by this, the reason that many airlines have unsubscribed one after another is that COMAC's technology is not as mature as Airbus and Boeing. On the other hand, it is also because these two overseas companies are interfering. Do not think that these large-scale overseas manufacturing enterprises are good goods. In recent years, they can form a monopoly, and they do not know how many times they have done indiscriminate activities. In that year, Luo He can even bribe Tanaka. It's very humane for them to steal orders behind their backs. "

Zhang Yunfeng smacked his lips and nodded and smiled: "as you said, COMAC is doomed to lose now. These 30 orders can't help COMAC in any way. So it's time for COMAC to go bankrupt, right?"

"Not necessarily." "After all, it's a state-owned enterprise and a large state-owned enterprise directly under the central government. It's impossible for the state to see it fall down. If this project fails, it's also possible for the state to invest more money to support it or carry out research and development of other projects," Liu explained

Zhang Yunfeng nodded and said with a smile, "in this case, I need the engine production line of COMAC first. The high-precision machining center required by the leader will be built in three months, but I want to take over the production line of COMAC first."

Liu said with a smile, "it's OK. I can give you a promise first. You can take over at any time."

Zhang Yunfeng is thinking about it. If COMAC is struggling now, it's better to connect its aircraft assembly line together. In this way, with its hardware foundation, together with Dongchen's scientific and technological strength, as well as Xiaoer, an excellent and capable general, Dongchen can get on the horse civil aviation engine and civil Aviation airliner in a very short time Eye.

In the field of civil aviation airliners, the competition is not fierce. Boeing and Airbus are fighting each other, and the product line is very small. What makes money is the main line airliners with more than 100 seats. In fact, there are three models that are enough to cover the whole civil aviation, namely, 100200 seat, 200400 seat, 400 seat or higher, 400 seat or higher Not only is it not capped, but now the development of main line civil aviation and the current fierce competition of airlines. The application field of aircraft with more than 600 seats is very narrow. If the airline does not have an excellent route and a large number of passenger flow, it is suicidal for the airline to buy a super large passenger aircraft. In addition to these three types, there need to be three corresponding cargo aircraft models, which are for civil aviation passengers It can be realized with a change.

As for the engine, it's even simpler. It's all based on the thrust. It's a small thrust engine that adapts to frequent short-range takeoff and landing, with a thrust between 20000-30000 pounds. Engines suitable for medium, small and medium airliners, or short-range medium and large airliners, with thrust between 30000-70000 lbs. There are also large thrust engines for medium and long-range, medium and large airliners, with thrust ranging from 70000 to 120000 pounds.

Zhang Yunfeng's current engine technology can become a reality. Compared with the current engine, compared with the thrust engine, the weight of the engine will be reduced by at least 30%, the service life will be more than three times, the fuel consumption will be reduced by 4050%, the noise will be reduced by 3040%, and the maintenance cost in the later period will be doubled. If this engine is produced, the pattern of the whole civil aviation field will be reduced Great changes will take place, and the cost of civil aviation transportation will be greatly reduced. Due to the sharp drop in fuel consumption, the maximum range of the aircraft will be greatly increased.

New technology will have a great impact on the transportation of the whole world.

and this is just engine technology. If Dongchen can build its own aircraft, Zhang Yunfeng has many advanced technologies that can kill Boeing and Airbus, and make Dongchen's aircraft have better performance, greater safety and more advanced technology level than Boeing and Airbus. At that time, the field of civil aviation will no longer be Airbus and Boeing The two monopolizes, but only Dongchen is the only one.

If Dongchen wants to continue to improve its position as the industrial overlord, the civil aviation field is the most suitable route.

The high-level leaders gave an exchange proposal. Dongchen built a high-precision machining center for the country, and the country handed over the engine production line of COMAC to Dongchen. This time, Zhang Yunfeng didn't reduce his price. He actively agreed to this very cost-effective exchange method for him, high-precision machining center, for other enterprises or countries, maybe It's very difficult, but for Dongchen, it's nothing more than to let Xiaoer work hard and rebuild a new set. The original transformation is continuous self transformation, that is, to use the equipment with one millimeter precision and advanced technology to produce 0.5mm equipment, and then use 0.5mm equipment to upgrade to 0.1, and so on. But now, Dongchen has 0.001 micro A complete set of meters precision equipment, once again to create a set of the same equipment, there is no such trouble.

The state is responsible for providing the basic equipment. Zhang Yunfeng then hands it over to junior two for upgrading. However, in more than 20 days, a set of high-precision processing equipment of the same level as Dongchen high-precision processing center has been built, and the whole set of equipment has been transported to Yanjing for installation and debugging. Once the equipment is delivered, Dongchen high-precision processing center is no longer the only one in the world The existence of a top player is equivalent to building a parallel opponent for oneself.

However, it has no impact on Zhang Yunfeng. What he really relies on is the advanced technology in the super learning system, rather than the pure high-precision processing ability. Without the support of advanced technology, even with such high-end processing technology, it is impossible to produce even one Dongchen S1.

At the same time of building the second set of equipment, Zhang Yunfeng's own manipulator production line established in Jiangcheng has produced nearly 1000 small-sized second-hand customized manipulator for him. These manipulator are specially developed for COMAC's engine production line. When the second set of high-precision processing equipment is installed and debugged in Yanjing, Zhang Yunfeng will return immediately Return, send these mechanical arms to Zhonghai, where you can directly take over the engine production line of COMAC, and immediately start the transformation.

Complete set of processing equipment, using three transports
