In the private room, Zhang Hao carefully spread out the drawings with both hands, flipping through the past one by one, his demeanor was like a gambler who fried Jinhua and took three of a kind, the more he looked at it, the more he liked it, and the more he looked at it, the more excited he became.

Zhou Kai also hurriedly stepped forward, stood behind Zhang Hao, only glanced at it, and was directly stunned.

That perfect drawing skills, at first glance, seem to be from the hands of a famous master, and it is by no means a novice can draw.

But according to Zhou Kai's understanding, Yang Tian's drawing level in college was still in the state of graffiti of primary school students, why did it improve to such a point after two years, and it was not so fast to ride a rocket.

And when Zhou Kai calmed down and really went to look at the design drawings, he was surprised to find that he couldn't understand it at all.

Looking back again, looking at Yang Tian who was crossing Erlang's legs and drinking tea leisurely, Zhou Kai's mind also had a momentary crash, is this still Yang Tian?

At this time, Zhang Hao had already finished reading the drawings in surprise, his brows furrowed, and he hurriedly came to Yang Tian's side, and asked urgently: "Little brother, what are the considerations for you to design that combustion chamber with a dome cone?" Also, at the bottom of the skirt of the piston, why is there only one French pattern, according to the conventional design idea, it should be three French lines? ”

Zhang Hao held the drawings and nodded, his demeanor was like a student asking a teacher, which also made Zhou Kai completely dumbfounded, and secretly pinched his arm, and said in his heart that all this is not a dream?

Regarding Zhang Hao's question, Yang Tian was also a little dumbfounded. He can print out this drawing, but the specific reason for this design is explained in the information, but Yang Tian can't understand it.

To put it bluntly, Yang Tian's heat is still far from being in this regard, and he really has no comparable surname with Zhang Hao's old qualifications.

But we don't understand, but pretending to be big will be, Yang Tian just glanced at Zhang Hao and said, "I design it like this, naturally I have my reasons." ”

Zhang Hao nodded thoughtfully, and secretly said that the changes in these details are probably the core secret of Yang Tian's engine design, and how can people easily tell it when they meet for the first time.

"It's me who is abrupt, little brother." Zhang Hao laughed, and his attention returned to the drawings.

The design of the engine is perfect, according to Zhang Hao's experience and intuition, if it is really manufactured, and then reaches the level of technology, the efficiency of this engine will be several times more than any engine on the market.

Why is the decline of Dongjiang Machinery No. 1 Factory, it is not that scientific and technological research and development can not keep up, when others are using imported high-end engines, they can only use old-fashioned engines.

The core gap has created a fundamental gap in products, and it is good if the factory has not closed down.

So seeing the design drawings of such an engine now, how can Zhang Hao not be excited.

Taking a deep breath, Zhang Hao tried to calm himself down, Yang Tian came to the door with the drawings, what was it for, to promote products, or to seek cooperation?

But no matter what purpose Yang Tian came with, Zhang Hao decided that he would be satisfied and that he must leave the design drawings of this engine.

"How about this engine, Zhang Gong is satisfied?" Yang Tian put down the teacup, asked with a smile, then glared at Zhou Kai, who was still standing stupidly, and shouted in a low voice: "Kaizi, what are you doing in a daze, ask the waiter to serve the food, let's talk while eating." ”

"Yes, yes, let's talk while eating." Zhang Hao came back to his senses, hurriedly approached Zhou Kai, and arranged in a low voice: "According to the highest specifications, go back to the factory for reimbursement." ”

Zhou Kai's brain was already a little short-circuited, and he looked at Zhang Hao, who was known as the number one iron rooster in the factory, in a daze, and went to arrange it.

Seeing Zhou Kai leave, Yang Tiancai took back the drawings from Zhang Hao's hand, rolled them up, put them beside him, and said with a smile: "That Zhang Gong, if you are satisfied with this engine, then let's talk about the price." ”

"Price, yes, Yang Tian, you are Zhou Kai's classmate, then I'll call you Yang Zi, this engine was really designed by you alone?" Seeing Yang Tian put away the drawings, Zhang Hao's eyes were also a little reluctant, and he forcibly withdrew his gaze and said.

Zhang Hao said this, firstly, to play the friendship card, and secondly, to ask whether Yang Tian completely owned the exclusive right to this engine drawing.

No matter what kind of cooperation, patent rights are a big problem, the factory has also tried to introduce foreign high-end engines before, but the patent rights have suffered a lot.

After eating a trench and growing wise, Zhang Hao also had to ask the situation clearly.

Yang Tian nodded without the slightest shame, pasted and copied it himself, and printed it out with him, but it was not designed by one person.

"In terms of property rights, Zhang Gong, you can rest assured that this drawing, from design to completion, is all out of my own hands, and my patent application has been submitted, I think I will be able to come down soon, and I will be able to provide complete transfer documents when the time comes." This time, Yang Tian was also fully prepared, and the patent application was handed over first, but there was a process that took a certain amount of time.

Zhang Hao nodded with satisfaction and said: "But Yang Zi, you also have to know that I am only the chief engineer of the factory, even if we talk at the moment, we can only have a preliminary intention, and we have to decide what to do." ”

At this point, I am afraid that Yang Tian will regret it, Zhang Hao hurriedly said: "But don't worry, your engine has a broad market prospect, and I think the factory leaders will not be able to pass it." ”

Yang Tian nodded, naturally he didn't think that he would be able to negotiate the matter today, hand over the drawings and take the money and leave.

At this time, Zhou Kai also walked back, and soon, a good banquet was served on the table, and there was a lobster weighing half a catty in the center, a full hard dish!

Yang Tian's poor jingle sounded, and he spent many days making noodles, and when he saw the delicious food on this table, he was also a little drooling.

But because Zhang Hao is here, he can't be too embarrassed, no, he endured his hunger, Yang Tian asked: "Zhang Gong, I'm a straight temper, this engine, I want to transfer it, you can buy it out at one time, or you can authorize it." ”

These are the two ways of cooperation that Yang Tian thought of before he came, it is okay to buy out the surname once, anyway, guarding an alien history museum, Yang Tian does not have to stick to this engine, as an egg-laying rooster. As for the authorized use, Yang Tian can also accept it, but it is just a little troublesome.

Zhang Hao nodded, Yang Tian was willing to transfer, he was very excited, he could see the potential of this engine at a glance.

opened a bottle of Moutai, Zhang Hao got up and poured it for Yang Tian, and looked at Zhou Kai's eyes twitching, this blink of an eye, the identities of the two seemed to be reversed, who is asking for this!

"Yang Zi, let's not talk about this engine, it's perfect, but there is one key point. I know the situation in the factory best, like this engine, there are some high-precision components, I'm afraid it can't be processed. At this time, Zhang Hao also calmed down and thought more.

In recent years, domestic manufacturers have been catching up, and in terms of engine design, it is not too weak, but what bothers many manufacturers is that they can design it, but they can't produce it.

Compared with foreign countries, domestic processing technology is still somewhat backward.

Therefore, the engine drawings that Yang Tian brought, if you can see it with light, but you can't make it, it is useless.

"Also, if the efficiency of the engine goes up, the requirements for materials will be higher, and the materials with high temperature resistance and pressure resistance in key parts are also a big problem." Zhang Hao continued.

These two questions in a row also stopped Yang Tian, and when he stopped gnawing on the lobster, Yang Tian also woke up that he was indeed thinking too simple.

Alien technology is indeed advanced, but it is too advanced to be made on Earth.

Although the engine drawings taken out by Yang Tian are not too advanced, that is, they are decades ahead, but there are some key places that must be changed according to local conditions and the specific situation of the earth's scientific and technological level.

After a deep sigh, Yang Tian waved his hand with a nonchalant expression, and said, "Don't worry, this Zhang Gong, I considered this aspect when I designed the engine. If the material is not up to the mark, we can look for inferior alternatives, and the performance will decrease, and it will not drop too much. As for the processing and manufacturing equipment, I have also designed a few drawings, and I can also take them out and transfer them to you when the time comes. ”

In terms of materials, Yang Tian is not completely sure, but the lathe for processing, Yang Tianxun asked the seven stars and eight arrows, and he should be able to find a lathe that meets the standards.

The lathe, simple and complex, is almost the same thing as the engine, and it is also a process of industrial accumulation.

Like today's high-end CNC machine tools in the world, they are all 5-axis 5-linkage, or higher 6-axis 5-linkage.

In this regard, there are too many domestic differences, and many key technical secrets are blocked, so we can only manufacture high-precision CNC machine tools in small batches, which are used in the military industry, ordinary civilian, and the world's first-class level, which is still too far behind.

"What, you also designed the corresponding machine tool, what is it, multi-axis linkage, how many axes can it reach?" Zhang Hao raised these two questions, but he didn't think about embarrassing Yang Tian and asking for bargaining or anything, just talking about things, but who would have thought that Yang Tian would actually engage in relevant designs.

High-precision, Gao Gang's lathe, that can not be introduced if you want to, foreign manufacturers have been blocked, so Zhang Haocai said that he brought Yang Tian's engine design drawings, I am afraid it will not be produced.

Yang Tian's attention was back on the lobster, and he muttered: "I'll show you this when I'm free, that thing is quite complicated, and I can't explain it clearly for a while, and you can't understand it." ”

Zhang Hao nodded like a chicken pecking rice, without any disgust at Yang Tian's shocking tone.

The opposite one, but the real genius, the world of genius, how can mortals understand?

And Zhou Kai, who was on the other hand, held the wine glass blankly, unaware that the wine glass was pouring out, and the wine was flowing on his pants, drenching a large area.

Is this guy still the one I know?
