The perfect test of two 11-blade large side-inclined propellers made the military immediately make up its mind to order advanced submarine propellers from Dongchen in large quantities, China's submarines are divided into two categories, namely conventional submarines and nuclear submarines, various types of submarines are more complex, and the tonnage is different, the military hopes that Dongchen can design and manufacture propellers of different specifications according to its different levels of submarines, with the ratio of three propellers for every two submarines of the same type, Dongchen has received military orders as many as 120 fans.

Fortunately, the military is not greedy for merit, trying to complete the innovation and progress of the submarine in the shortest possible time, they set a contract period of up to two years for Dongchen, and in addition to the ten largest specifications of the eleven-blade large side inclined propeller, the size of the other propellers is relatively smaller, and the processing and manufacturing is easier.

State-owned high-end industrial processing enterprises, such as the military, aerospace field, these enterprises are waiting for the day to be able to be in the Dongchen high-precision machining center number, the core components, extremely high-precision reconstruction, but Dongchen is unable to undertake more national orders, just the submarine propeller list, has accounted for a lot of workload, after all, there is only one high-precision machining center, Dongchen also has to meet their own needs, so, the senior leaders are also a little worried about this, Not long after Zhang Wenhao returned to Jiangcheng, Director Liu came to the door again and brought a suggestion from the top management. That is, the state-funded and Dongchen helps the country to build a new high-precision machining center, so that the state-owned cutting-edge enterprises can jointly use the state-owned machining center, and can also better alleviate the urgent needs of the current cutting-edge enterprises.

It is better to teach people to fish than to teach them to fish, Zhang Wenhao understands this truth. However, Dongchen's high-precision processing technology is a master key to high-end industrial manufacturing. This kind of technology is not only important for a company, but even for a country. The state tried to get Zhang Wenhao to take out this set of technology, and naturally prepared enough exchange chips for Zhang Wenhao.

At the moment when Zhang Wenhao was considering, Director Liu threw a bombshell and said: "What the senior leaders mean is that this time, after Dongchen establishes the high-precision machining center, all the engine production lines on the side of COMAC will be handed over to Dongchen, haven't you always had the idea 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 Wenhao was overjoyed. He smiled and asked, "Give me the engine production line of COMAC?" What about COMAC's own large aircraft project? ”

Director Liu smiled helplessly and said: "COMAC's own project has little practical significance, and the large aircraft developed by COMAC itself has poor sales and is not good in performance." Cost-effective and other multiple advantages, taken together, can not compare with Airbus and Boeing, at the beginning, COMAC on the Malaysian aircraft project, with the intention of solving domestic demand. However, the current airlines will not do such a big favor, before the empty check is quite big, but after the large aircraft of COMAC off the assembly line, it has been unsubscribed a large number of aircraft, and now the total number of effective orders, is less than 30, the profit that these 30 can bring, far from enough to make up for the research and development costs of the entire project, and the only remaining order, the buyer also refuses to use the domestic turbofan engine, and COMAC has no way, so now the entire engine production line has basically entered an idle state. ”

Zhang Wenhao nodded and asked curiously: "Is COMAC now producing those thirty orders?" ”

Director Liu said: "The deposit for the 30 orders has been paid, but it is said that the buyers have the intention to unsubscribe, and now, Airbus is negotiating privately with several buyers, if they cancel the subscription and order the Airbus A320 instead, Airbus will give each aircraft a discount of 5 million US dollars." ”…,

Zhang Wenhao asked in surprise: "What is Airbus messing with inside?" A company as big as them shouldn't care about the order for these thirty planes, right? ”

Director Liu shrugged his shoulders and said: "You may not know much about this, the project of COMAC has a direct conflict with Airbus A320 and Boeing 737, if it is really launched, if more than 200 orders were retained when it was launched before, then COMAC will usher in a huge leap, foreign countries dare not say, but in China, Airbus and Boeing's aircraft sales of the same class will be greatly affected, the reason why there are airlines unsubscribed one after another, on the one hand, the reason is that the technology of COMAC is not as mature as Airbus and Boeing, on the other hand, It is also because these two overseas companies are in the way, don't think that these large overseas manufacturing companies are good goods, they have been able to form a monopoly over the years, and they don't know how many times they have done indiscriminate deeds, back then, Lockheed was even able to bribe Kakuei Tanaka, they just snatched orders behind their backs, which is already very humane. ”

Zhang Wenhao smacked his lips, nodded and smiled: "As you said, COMAC is doomed to defeat now, and these 30 orders will not be of any substantial help to COMAC's situation, so it seems that it should be a matter of time before COMAC goes bankrupt, right?" ”

"Not necessarily." "After all, it is a state-owned enterprise, and it is a large central enterprise directly under the central government, and the country cannot see it fall, and if this project fails, it is very possible for the state to invest some more money to support it, or to carry out research and development of other projects," Liu explained. ”

Zhang Wenhao nodded and said with a smile: "In this case, I will ask for the engine production line of COMAC first, and I will complete the construction of the high-precision machining center required by the leader within three months, but I want to take over the production line of COMAC first." ”

Director Liu smiled: "There is no problem with this, I can personally give you a promise first, and you can take over at any time on the side of COMAC." ”

Zhang Wenhao was thinking in his heart that if Commercial Aviation is struggling now, then it would be better to take over its aircraft assembly line together, in this way, with its hardware foundation, coupled with Dongchen's scientific and technological strength, and Xiao Er, an excellent right-hand man, Dongchen can launch a civil aviation engine in a very short time. and civil airliners.

In the field of civil aviation passenger aircraft now, the competition is not fierce, it is nothing more than Boeing and Airbus fighting, and the product line is very small, and the real money is more than 100 trunk passenger aircraft, in fact, overall. There are three models that are enough to cover the entire civil aviation, namely the 100-200 seats, 200-400 seats, and 400 seats and above. The level of more than 400 seats is not capped, as far as the development of trunk civil aviation and the current competition among airlines is fierce. More than 600 seats, the field of application is very narrow, if it is not for the excellent route and a large number of passenger flow, airlines to buy super-large passenger aircraft, it is simply suicidal, in addition to these three, there are also three corresponding cargo aircraft models, which can be achieved on the basis of civil airliners.

As for the engine, it's even simpler, everything is divided by thrust. Small thrust engines adapted to short-range frequent take-off and landing, with thrust between 20,000-30,000 pounds; Engines suitable for medium-haul, small and medium-sized passenger aircraft, or short-range medium and large passenger aircraft, with a thrust between 30,000 and 70,000 pounds; There are also high-thrust engines suitable for medium and long-range, medium and large passenger aircraft, with thrust ranging from 70,000-120,000 pounds.

Zhang Wenhao's current engine technology can be turned into reality. Compared with the current engine, compared with the thrust engine, the weight is reduced by at least 30%, the service life will be more than three times, the fuel consumption will be reduced by 40-50%, the noise will be reduced by 30-40%, and the maintenance cost will be reduced in the later stage. It will also decline exponentially, if this engine is produced, then, the pattern of the entire civil aviation field will change dramatically, 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 technologies will have a great impact on the transportation of the whole world.

And this is only engine technology, if Dongchen can build its own aircraft, Zhang Wenhao has a lot of advanced technology enough to kill Boeing and Airbus, enough to make Dongchen's aircraft, than Boeing and Airbus have better performance, greater safety, and more advanced scientific and technological level, at that time, the field of civil aviation, I am afraid that it will no longer be the monopoly of Airbus and Boeing, but only Dongchen alone.

If Dongchen wants to continue to enhance its position as an industrial hegemon in the next step, the civil aviation field is definitely the most suitable route

The senior leaders gave it, which is equivalent to an exchange suggestion, 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 Wenhao did not lower his price again, and took the initiative to agree to this very cost-effective exchange method for him, high-precision machining center, for other enterprises or countries, it may be very difficult, but for Dongchen, it is nothing more than to let Xiao Er work hard and re-transform a set, the original transformation is continuous self-transformation, that is, Using equipment with a precision of one millimeter, and advanced technology, to produce 0.5 mm equipment, and then use 0.5 mm equipment, self-upgrade to 0.1, and so on, but now, Dongchen has a full set of equipment with 0.001 micron accuracy, and it is not so troublesome to build the same equipment again.

The state is responsible for providing basic equipment, Zhang Wenhao and then handed over to Xiao Er for upgrading, but in more than 20 days, a set of high-precision machining equipment at the same level as Dongchen high-precision machining center has been built, and the whole set of equipment has been shipped to Yanjing for installation and commissioning.

However, this has no impact on Zhang Wenhao, he really relies on the advanced technology in the super learning system, rather than simple high-precision processing capabilities, without the support of advanced technology, even if he has such a high-end processing technology, it is impossible to produce even a Dongchen S1.

At the same time as the construction of the second set of equipment, Zhang Wenhao's own robotic arm production line established in Jiangcheng has produced nearly 1,000 robotic arms tailored for him, these robotic arms are specially developed for the engine production line of COMAC, and when the second set of high-precision processing equipment is installed and debugged in Yanjing, Zhang Wenhao will immediately return and transport these robotic arms to Zhonghai, where he will directly take over the engine production line of COMAC and immediately start to transform.

A complete set of processing equipment, using three conveyors for transportation. Zhang Wenhao took a private jet to Yanjing first, thinking of coming to Yanjing, Zhang Wenhao was full of thoughts about Su Ruoran, since the last time, he asked for Su Ruoran's first night, until now, he has not been able to take care of going back to Yanjing to see her. Zhang Wenhao's heart was both missing and full of guilt.

This time, Zhang Wenhao was ready to surprise Su Ruoran. After landing at Yanjing Airport in the afternoon, Dongchen Pharmaceutical's people made a special trip to the airport and sent Zhang Wenhao an S3C. Immediately, Zhang Wenhao drove to Yenching University as soon as possible, and at the flower shop outside the school, Zhang Wenhao bought a bouquet of roses, and then he returned to the campus of Yenching University after a long absence, and inquired about the teaching building where Su Ruoran took classes.

After waiting downstairs in the teaching building for about 30 minutes, the bell rang at 5:20 p.m., and basically the day's classes were over by now. The students began to pour out of the teaching building, or go back to the dormitory to rest, or go directly to the cafeteria to eat, and in the midst of the flow of people, Zhang Wenhao stood in the square below the teaching building with flowers in his hand. It has attracted a lot of people's attention. …,

When Su Ruoran walked out of the teaching building with a fellow bedboarder, her bedfellow recognized Zhang Wenhao at a glance, pointed to Zhang Wenhao holding flowers in the distance in surprise, and shouted: "If you look at who it is!" ”

Su Ruoran hadn't seen Zhang Wenhao before, and when she heard the words of her bedmate, she subconsciously raised her head. looked in the direction of her finger, and at a glance, even though she recognized that it was Zhang Wenhao who was looking at her with flowers in her hand in the distance, it was Zhang Wenhao who she had been thinking about for a long time, and then, Su Ruoran screamed in surprise, threw away the book in her hand, and ran towards Zhang Wenhao quickly!

For Zhang Wenhao, Su Ruoran has hardly thought of him for a moment during this time, Su Ruoran is a reserved and dedicated girl, from falling in love with Zhang Wenhao to dedicating everything to him without reservation, it is enough to prove that she has deep feelings for Zhang Wenhao, but Su Ruoran is indeed a reasonable girl rarely found in this world, she understands in her heart that for Zhang Wenhao, what is the most important thing, although she misses him very much, but she has never taken the initiative to ask Zhang Wenhao to come back to see herself on the phone, the reason is that she knows, Zhang Wenhao's career now is the most important thing for him, in front of a man's career, Su Ruoran willingly suppressed his private feelings.

It's just that she never expected that the man she had been thinking about for a long time suddenly appeared in her teaching building with flowers in her hand and appeared in front of her eyes, this excitement made Su Ruoran difficult to control herself at all, she strode towards Zhang Wenhao, and when she arrived at Zhang Wenhao, Zhang Wenhao had already spread out his hands and waited for her hug.

Su Ruoran jumped into Zhang Wenhao's arms like a child, and Zhang Wenhao held the flower in one hand, and easily hugged Su Ruoran with the other hand, Su Ruoran hugged Zhang Wenhao excitedly and screamed, and Zhang Wenhao also hugged her and turned around in place several times, then put her down, ignoring the hundreds of students around her, bowed her head, and kissed Su Ruoran in public.

Su Ruoran wouldn't care about these for a long time, this is her man, the man she loves deeply, his sudden appearance made Su Ruoran excited, don't say that he is being watched by hundreds of people now, even if he is watched by the whole world? She also did not hide her love for Zhang Wenhao and her excitement about his sudden appearance in front of her.

After about a minute or two of kissing, Zhang Wenhao put Su Ruoran down, and then handed the flower in his hand to Su Ruoran's hand, and said softly: "Ruoran, I hope you can forgive me for not being able to be by your side for a long time." ”

Su Ruoran gently took the flower, her heart was full of happiness and sweetness, she threw herself into Zhang Wenhao's arms again, and choked in his ear: "I have never blamed you, where is the so-called forgiveness?" ”

Saying that, Su Ruoran hugged Zhang Wenhao's neck and said with a smile: "Since you are here, I won't go to self-study at night, call my mother now, and let's go back to eat in the evening." ”

Zhang Wenhao nodded and said with a smile: "I'm going to stay in Yanjing for two days, I have something to do, these two days, do you want to take a leave to accompany me?" ”

Su Ruoran glanced at Zhang Wenhao, and said angrily: "You are here to do something, not to play, do you still want to take me to do business?" ”

Zhang Wenhao smiled slightly, and said: "Then what's the matter, besides, this time I'm here, I don't want to participate in the specific things, I'm just responsible for the handover of a project, the specific work is done, and I'll sign it when I accept it." ”

Su Ruoran smiled: "If you can accompany me for a morning or an afternoon tomorrow, I won't come to class." ”

Zhang Wenhao nodded and said: "Tomorrow is installation and commissioning, and the day after tomorrow, I will take the time to go over and go through a process, and I can accompany you all day tomorrow." ”

Su Ruoran was excited for a while, and said, "That's great, I'll call my mother now, ask her to hurry home and cook, and then call the class guide, I won't come tomorrow." ”

Su Ruoran held flowers in her hand and sat in the S3C driven by Zhang Wenhao, and then, Zhang Wenhao started the car and drove out of the school, while Su Ruoran sat in the co-pilot and carefully put the flowers on her legs, then took out her mobile phone and called Nie Minhui.

"Mom, Wen Hao is back, let's go home now, you should come back quickly, and eat together in the evening."

Nie Minhui was driving on the way home at the moment, when she heard Su Ruoran's excited voice, she shook her head and smiled helplessly, turned on the direction signal and parked the car on the side of the road, and said very apologetically: "If so, say hello to Wen Hao for my mother, and tell him by the way, my mother is very sorry, I have to go to Zhonghai in the evening, and it will take about two days to come back, so I can't accompany you." (Your support is my biggest motivation.) )
