In Liu Lang's office, in addition to these models "dazzling", the most are books, and there are nearly 10,000 books in the bookcase on the entire wall, most of which are professional reference books, as well as books from the world's top paper magazines.

In addition to these books, there are six blackboards, each four or five square meters, on which complex mechanical drawings are drawn, and there is a dazzling amount of data.

"Liu Lang, this is the blueprint of the big plane you got last time, right?"

Jiang Botao also studied this drawing in detail, of course, his knowledge could not be further studied, and he could only distinguish it.

"That's right, this is the engine drawing of a large aircraft, I have done a very detailed study of this engine, and I have some ideas of my own, such as the shell design of the Soviets is too rough, I have two ways to slim it down, which can reduce the weight of about three hundred kilograms!"

Liu Lang explained to the people present as he spoke.

", I don't understand!"

Jiang Botao shook his head and was confused, not to mention him, even the entourage who came with him couldn't understand, this was too professional.

"Okay, Liu Lang, it's useless for you to tell us, you don't understand, you should tell Qin Lie and their experts about these things, do they know?"

"I haven't had time to tell them yet, besides, this is what I came up with alone, Qin Lao and they have a group of people, all of them are experts, they should be able to come up with it!"

"What? You don't tell them such important information?

Jiang Botao was a little anxious.

In fact, these drawings and design schemes are Liu Lang's works when he usually trains himself, he has not systematically learned foreign industrial knowledge in recent years, Liu Lang is also a person, he will fall behind if he does not learn, and he needs to continue to learn, but his learning method is different from ordinary people.

Ordinary people should always be in contact with those advanced concepts and skills, if there is a year or two without learning, then his knowledge reserve will be behind, Liu Lang is different, because knowledge is coherent, for example, a forging technology is divided into five steps, after technical improvement may be reduced to four steps, this is a kind of progress.

Ordinary people can directly learn the four-step method, no need to figure out the reason for improvement, Liu Lang's brain has beyond ordinary people's thinking ability and logical ability, a method recorded in the mind can automatically analyze it, and then analyze a simpler method, so his learning method is to contact more basic knowledge, on this basic knowledge to deduce a higher level of knowledge.

This self-derivation method belongs to Liu Lang's "unique skills", ordinary people can't learn it, Liu Lang is through this way of learning to make his knowledge reserves not lag too far behind, of course, every month Moran will send him papers from various scientific magazines in the United States, many of these papers involve theoretical knowledge, Liu Lang always grasps the international dynamics through this kind of learning.

"Jiang Lao, let's put aside the things of this engine first, today we are talking about smelting materials, well, this is the information, one for each person!"

Liu Lang handed over a stack of more than 40 pages of materials to everyone.

The directors of the metallurgical enterprises immediately took over, and they wanted to take a cursory look at them first, but they were suddenly "trapped" and unable to extricate themselves.

"Baby, this is a baby!"

Several people said in unison.

"Well, mechanical properties, elasticity, strength, hardness, plasticity, toughness, yield point, tensile strength.

Chemical properties, physical properties, Rockwell hardness, dimensional hardness, corrosion resistance, oxidation resistance, chemical stability, casting properties.

Fluidity, shrinkage, segregation tendency, forging properties, welding properties, lattice structure of metals, alloy structures, including ferrite, austenite, cementite, pearlite, and heat treatment of steel......... These have the most detailed data, and with this material, our factory director can ......... It can be smelted in the shortest possible time!"

Shougang's factory chief shouted.

"It's the same with our Shanghai Iron and Steel Co., Ltd."

"Our Angang will be faster!"

These are experts in the domestic metallurgical industry, is knowledgeable, this information is too detailed, all kinds of data and various parameters have, it is completely hand-in-hand to teach you, of course, this can not be said to take it to smelt, the smelting furnace and the ability of workers are also to be considered, but this is a subjective reason, can be self-improvement, objectively there is no problem at all, for example, this is like a road to success, the road has been paved, the rest of you just walk over it, it's just a matter of time.

Kaminsky, who was smoking a Chinese cigarette on the side, grinned, although he didn't understand what the other party was talking about, but he could know by looking at his expression that he was enjoying the feeling of satisfaction at this moment, and he could only be "crushed" everywhere with Liu Lang, which was not pleasant.

"Don't worry, I want to explain, this material is really precious, even I am reluctant to take it out, of course, since it is taken out, there is no condition, but I told the national large aircraft research group about this matter, the above means to ensure the research of large aircraft engines, that is to say, your first task is to smelt the materials suitable for aircraft engines. ”

Jiang Botao also knows about this, but he also agrees, now the country's large aircraft engine research and development has made great progress, the key problem is that the material is not up to par, and the material problem is the basic ability, the country has natural defects in this regard, not a breakthrough can be made in a moment, but now it is different, Liu Lang's material solves a big problem, if quantitatively viewed, at least the country's material smelting level can be improved for at least seven years, so the country immediately made a decision after getting the news, let several smelters cooperate with the large aircraft research team。

Several directors of the smelter did not hesitate to listen to this, and immediately agreed.

There is no need to hesitate at all, okay, I got a priceless material for nothing, and the company can make money as long as it successfully smelts special steel, besides, the country's high-level officials have ordered that they can still have different opinions?

"Well, since everyone has no opinion, then I will explain to you the characteristics of Soviet aircraft engines, and I have also prepared a material, which is specifically for some supplements to large aircraft engines. ”

Liu Lang said as he took out another material.

"And?"

This material doesn't even know Jiang Botao.

Liu Lang also ignored Jiang Botao, picked up chalk and wrote various data on the blackboard.
