Zhang Haoran was at the dinner table and whispered to Jin Xiaopeng: "Let's rent a car first, buy a car now, you can't shake it in the Year of the Monkey, let Liu Mingyuan drive these two girls to and from work first, and add 2,000 to Liu Mingyuan's salary every month, his family lives quite far away, and it is more convenient to drive by himself." What's the matter in the center, let him drive to do it, electrician and driver, you think it's okay? ”

Jin Xiaopeng told Liu Mingyuan and the other three people this information, Wu Xiaoxiao and Liu Yuming had little stars in their eyes, this benefit is good, really. I've been worried about traffic on the road. No traffic jams, no overtime, and at least three hours back and forth on the road.

Liu Maomao and Mao Dan came over to say hello from time to time, one hundred and eight slices of roast duck are indispensable, take care of Liu Yuming, and two Sichuan hometown dishes, boiled meat slices and dry braised fish.

Liu Yuming shouted: Ba Shi Bashi.

After eating, Liu Mingyuan called the waiter to settle the bill, the waiter didn't dare to be proficient, and called Mao Mao, how dare Liu Maomao collect money, that is Zhang Gongzi, although he is surprisingly low-key now, it is also one of the three sons, plus Jin Xiaopeng, a descendant of the regiment, to collect their money, a little feeling like looking for a draw.

Jin Xiaopeng's eyes glared and said: "In the future, this is one of our designated canteens, we have money, and one month's interest is enough to buy your canteen." ”

Liu Maomao: We are obviously a restaurant, when will it become your canteen, and bring one, how many canteens do you have, anyway, I am also the second generation, the rich kind, why do you have money A month's interest is enough to buy this canteen, no, it's a big restaurant. You are the second generation of officials, so rich, do your parents know? It's not going to be a run out of the ground.

Thinking like this in his heart, he saw Jin Xiaopeng take out a card, black with narrow gold edges, and stuffed it into his hand, and heard: "Swipe the card, hurry up, we still have to do something." ”

He changed to a flattering voice again: "Mingming." Is this cafeteria okay? ”

Liu Yuming???? Is it speaking to me?

What kind of card is swiped, Liu Maomao threw the black card on the table, and the person was gone. These are all masters, and they are all better than me.

The decoration has not officially begun, Wu Xiaoxiao has already entered the working state, with the assistance of Liu Yuming, the equipment list will be replenished soon, and the budget is 130 million.

Zhang Haoran was a little painful, but remembered that if he conquered the heat-resistant material pass, these would be small money.

Liu Yuming also started headhunting practice according to the plan. The phone is busy all day long.

Jin Xiaopeng is very worried, the national team has been engaged in it for so many years, and now it is still stuck in the material of 1,000 degrees, and we insist on gnawing on the material of 2,000 degrees.

It is known that metals such as nickel, rhenium, cobalt, etc., even if they are drawn into single crystals, have problems of one kind or another. We're all about to make a whole of the top materials of the airline?

Zhang Haoran knew that it was not yet time for a showdown, and wait, after the experimental center had a look, it would definitely come up with something mysterious and magical, so that the materials and processing technology of high-temperature resistant metals would reach a new level.

It is the largest equipment in the experimental center, the vacuum furnace has arrived, the smallest is also large, this is the most important equipment, and it took more than a month to dismantle and rebuild the small courtyard before the installation and commissioning was completed.

But how can you get completely top-notch materials, these days, as soon as I have leisure, I automatically make up all the progress and papers I see in the school library and the national library, many theories are established, and there are great prospects, but the materials are not satisfactory, advanced theories are just theories, and if you want to make actual products according to theories, it still needs a lot of exploration, and it is possible to transform theoretical things into products.

Seeing that the experimental equipment was installed in place one by one, although Zhang Haoran was anxious, he was still chatting with Jin Xiaopeng, Wu Xiaoxiao and others on the surface.

Wu Xiaoxiao and Liu Yuming found that Zhang Haoran's theoretical knowledge is really amazing, and in the chat, they explained the world's top research theories in simple terms, especially in metal physics and chemical physics.

Zhang Haoran and the beads in the brain nucleus are now communicating more and more smoothly, and now the following three steps are needed to make advanced aviation development, each step is the world's top scientific and technological theory, and has not yet been put into practice.

To do is to be the top, leading the world's aviation development technology, so that Huaguo can lay the air superiority situation in one fell swoop, Zhang Haoran secretly made up his mind.

Step 1: Hangfa has two materials, one is a high-temperature resistant material, which can work for 10,000 hours at a high temperature of 2400 degrees with anti-oxidation coating protection without deformation or damage. After 10,000 hours, the coating can be replaced. The other is a lightweight composite material, which can withstand high temperature of 650 degrees, work for 12,000 hours, strong oxidation resistance, no deformation, no damage, and no wrinkling.

Step 2: Strengthen the processing technology, make the whole blisk, remove as much mortise and tenon and bolt fastening parts as possible, and greatly reduce the weight of the hangfa.

The third step: the introduction of ramjet engine theory, open up the second air intake, directly into the combustion chamber, make up for the lack of air intake during high-speed operation, resulting in a decrease in thrust, solve the problem of small duct than aviation engine, and further reduce the volume and weight of small ductway aviation engine.

Of course, there is also the enhancement of the aircraft's own strength, when cruising at 3 times the supersonic speed, the strength requirements for the fuselage are very high, otherwise it will cause disintegration in the air, and the high-strength metal will solve the problem of the disintegration of the aircraft under high-speed cruise, but the weight of the aircraft will affect the bomb load and the burden of the aviation engine.

Modern aircraft greatly use high-strength polyester composite materials, but Huaguo production can not produce the top high-strength polyester composite materials, although under laboratory conditions can synthesize more advanced polyester composite materials, not to mention from the world's top is a lot worse, that is, in large-scale production, there are also a lot of problems, such as wrinkle resistance, anti-oxidation, anti-fatigue and molding, etc., there is still a big gap.

These material issues involve many disciplines. Metal Physics, Chemical Physics, Materials Physics, Mathematics, Construction Machinery, Industrial Design, Industrial Process and so on.

China has been poor and weak for hundreds of years, that is, in less than 40 years, before the country has prospered and flourished, but in the past, it has lagged too far behind in science and technology, and has also gone through a detour.

In the external environment, you can achieve rapid development in a certain field faster, but after all, other people's things are people's, as soon as the external environment changes, under the embargo, look back, only to know that you still have nothing.

Learn from the pain, no matter how good other people's things are, it is not as good as making them yourself, but there is too much time to miss, research and development, most of them are still in the stage of painting cats and tigers, spinning up and mapping, and then imitating, accumulating experience, but there is always a generation gap with others, and it is urgent to catch up!

The materials and processes are not good, and it is difficult to follow the cat and the tiger, and although the things made are usable, the performance indicators are still a lot behind the prototype.

The pain of China.

To be the world's most bullish hangfa, from imitation to leading, leading the whole body, every link is the most difficult. It's really hard to get started.
