Nomenclature: Industrial Wastewater Treatment System.

Price: 2500.

Category: Environmental protection equipment.

Detailed description: The use of electrical energy, through the core equipment conversion, to form a strong magnetic field, and then use the strong magnetic field to guide the pollutants in the industrial sewage to a specific container......

......

After Liu Lin filled in all the information, he checked it again in detail, and after confirming that there was no problem, he clicked (confirm) to submit.

"The first product on the host shelves: industrial sewage treatment system, the price is 2500, please check, please click to confirm that it is correct!" A pop-up window popped up.

Liu Lin saw a set of numbers (0/3) at the pop-up window.

What does this (0/3) mean?

What the heck?

Liu Lin smiled, touched his forehead with his left hand, what are you doing, big brother, what are the restrictions.

There seems to be an exclamation mark on the side, which should be an explanation, Liu Lin stretched out his index finger and pointed it.

"Window description: each window can only be on the shelves of three products, after the product is on the shelves, a natural month can not be operated, changed or off the shelves, if it is a physical product, after the transaction is successful, you can continue to put new products on the shelves in the vacant window, if it is a data package, you can operate after a natural month!"

I'll go, there are still such conditions, Liu Lin gave an example.

Big brother is a bit of a pit.

What's going on?

Can you still make people make good money?

Super Games: I know how to make money all day long, I don't let you make money, I want to take the trading platform to earn game currency, you think too much, wash and sleep, you have everything in your dreams.

Liu Lin looked at it, this lofty goal of making money is estimated to be dying ahead of schedule, so should this sewage treatment center be put on the shelves?

Liu Lin pecked and grinded, but decided to put it on the shelf, the negative formula can't be used to occupy the position, and he has to study and study it when he is free.

Click (Confirm)!

"Successful listing!"

No, that's it?

It's simple.

Liu Lin glanced at it, this is too simple, I thought there were some earth-shattering big moves.

Super Game: ......

After Liu Lin finished the operation, he withdrew, glanced at the side, and saw a small stone table with one eye, so he walked over directly, sat down, and slowly walked around the trading desk to see what technology he could see.

Of course, the front is what you can afford.

"Husband, what are you doing?" Liu Lin heard Zhou Ying's call from not far behind him.

"It's okay, I was checking the information just now, why are you here, girl?" Liu Lin heard this, turned his head, and saw Zhou Ying, who was holding a small pink umbrella, walked over, slipped his hand twice, quit the game, put his phone in his pocket and asked.

"I went to the office just now to take a look, it's already been renovated, and I heard Brother Yong say that you are walking around here, so I came to see you. Zhou Ying walked to Liu Lin's side, hugged Liu Lin's neck from behind, and leaned on Liu Lin!

"Then wait a minute, what do you have planned? Liu Lin patted the small stone bench next to him and asked.

"I don't have any arrangements, now I need office supplies!" Zhou Ying finished saying that Liu Lin felt that the sorrow in his eyebrows was gone, so he asked: "Seeing that you are happy, is the problem at work solved?"

"There's basically no problem, the rest of the matter has to be done slowly, this is not in a hurry. Liu Lin nodded and explained.

"That's good, just solve it, I know that my husband is the most popular, husband, let's go to dinner, it's almost twelve o'clock." ”

"Okay, let's go, it's time!"

“......”

Just when the fifth boss was thinking about how to talk to Liu Lin about the Precision Industry Group, the big boss made a phone call, and he started the mobile phone he had picked up.

"Big boss, are you looking for me?" Five minutes later, the fifth boss came to the big boss's office, and when he saw that the military's Meng Ministry-Chief was also there, he said hello: "Meng-Ministry-Chief is good!"

"Five bosses are good. ”

The fifth boss looked at the big boss suspiciously, waiting for an explanation, it seems that he has something to do with the military, otherwise Minister Meng would not be here.

"Minister Meng, come on!" The big boss saw the inquiring eyes of the fifth boss, nodded, turned his head and said to Minister Meng, who was sitting on the side.

"The five bosses are like this......

It turns out that this is the way it happened.

Rewind to three days ago.

A secret factory in the northwest, which cannot be found on the map, is brightly lit and full of people, and if anyone who knows this place, they will know that this is the empty 30 assembly center.

And today is the day when the empty 30 is assembled.

"Chief Engineer Wang (Wang Jiang), how is it, when can I test the machine?" a middle-aged man (Lin Fei) wearing a dark green military uniform with half white hair respectfully asked a gray-haired seventy-year-old man.

Behind the middle-aged man, there was a large group of people, all looking at this Wang Gong, who was almost seventy years old, worriedly.

Wang Gong (Wang Jiang), male, Han nationality, born in February 1950, from Wuhan, Hubei, doctor, researcher. Started working in September 1977; He graduated from Nanjing Institute of Aeronautics and Astronautics in 1982 with a bachelor's degree in aircraft design, and graduated from Beijing University of Aeronautics and Astronautics in 2008 with a doctorate degree in aircraft design.

Since 1982, he has successively served as designer, deputy director, director of the general office of the 993 Institute, director of the general design and research office of civil aircraft, director of the general division of civil aircraft, deputy chief designer, assistant to the director, deputy director, and vice president of the First Aircraft Design and Research Institute of Aviation Industry Corporation of China.

Anyway, it's a very awesome character!

"General Lin, everyone!" Wang Gong glanced at the people in front of him who were waiting for them and were hesitant, sighed and shook them gently: "There are thirty-five accessories that do not meet the technical requirements, although they are installed, but ...... Therefore, the empty 30 is an unqualified aircraft for the time being, and it is not allowed to test it!"

Thirty-five substandard fittings?

Substandard, defective aircraft.

Everyone's faces changed......

Quiet!!!

Silent!!!

There were even sobbing sounds.

"Chief Engineer Wang, can't you really test the machine?" Finally, General Lin looked at the people around him, took two deep breaths, and asked with difficulty, looking at Chief Engineer Wang expectantly, four years!

How many four years are there in life?

"No, defective aircraft, absolutely not allowed to test flight, and then we will dismantle, replace the unqualified parts, this assembly is just a trial assembly, see if there are any other problems, very fortunately, except for these thirty-five accessories, there are no problems!"

"That is to say, as long as we replace these thirty-five accessories with qualified ones, then our empty 30 can be tested for flight!" Wang Jiang looked at some people who were already sobbing non-stop, and some were constantly swallowing saliva, and his eyes kept drifting to the sky, and comforted.

"Everyone, I know that every part of the empty 30 is made by your own hands, and all the technologies are developed by ourselves, I am the chief engineer of the empty 30, and my feelings for the empty 30 are no less than yours!"

"But... This is an important part of our national defense, this is for our soldiers, and it must stand up to severe tests; what our army needs is a mature aircraft, not a problematic and defective aircraft; after our verification and discussion, if we forcibly test the flight, the flight time will exceed 200 hours, and there is a possibility of disintegration at any time!"

"So we are not allowed to test the machine, we have passed four years, tens of thousands of accessories have been manufactured, and now there are still 35 missing, we work harder, we can complete it, everyone cheer up!" Mr. Wang suppressed the emotions in his heart and cheered everyone up.

"There are only 35 parts missing, tens of thousands have been manufactured, and you are still 35 missing. ”

"Yes, yes!!"

"Right...... Isn't it just thirty-five accessories, grinding him out by hand?"

All of a sudden, the atmosphere changed, and the scene was impassioned and rubbed hands.

"Okay, everyone is late now, let's go back to rest first, nourish your spirit, the body is the capital of the revolution, okay, the project leaders go to the conference room for a meeting, and the rest go back to rest first!" Wang Jiang saw that the current morale finally returned, breathed a sigh of relief, and waved his hand.

In fact, although Wang Zonggong is already desperate in his heart, these thirty-five accessories are not as simple as he just said, and now it can be said that he has reached the processing limit accuracy, otherwise he will not install unqualified accessories in the air 30.

Empty 30 may be dying, four years of hard work is in vain, even if it doesn't die, it will be suspended, these several general leaders are all in charge.

But until the end, you must not give up.

Wang Jiang led a group of people into a large conference room!

"Chief Engineer Wang?"

"Let's all sit down!" Wang Jiang waved his hand, interrupting Lin Fei, who wanted to speak, and suddenly felt a few more wrinkles on his face, and sighed: "General Lin, those thirty-five accessories, we can't process qualified accessories at all." ”

"We can't process it?" Lin Fei was stunned for a moment, reacted instantly, and asked with difficulty: "Is there no way?" You must know that this is the hard work of tens of thousands of people in the past four years!"

“......”

"Let's analyze the reasons first, find the thirty-five accessories and analyze them, is it possible to ......?"

The Kong-30 carries the dream of countless people as a "strategic early warning aircraft," and if the strategic task of national defense is successful, it will fill the gap in our long-range strategic early warning aircraft.

"The first fitting R18 is a 360-degree welded shaft for supercritical wings, due to our empty 30, which emphasizes safety, practicality, accuracy and strength, and has very high requirements!"

"Now we have installed the R18, whether it is strength or accuracy, can not meet the requirements, and our technical parameters are far from the same, if forced test flight, at high altitude and high speed when the pressure reaches 5800M, R18 will burst instantly!"

"Because of the ratio of lift and drag, there is a direct relationship, the higher the lift-drag ratio, about 70% of the pressure and lift of the whole wing, will focus on the R18 accessories, that is to say, when the early warning speed reaches 500 km / h, the air 30 will disintegrate instantly. ”

"Wang Zonggong R18 is too difficult, can we change the structure, for example, pneumatic rotation structure, hydraulic turning structure, etc. are our very mature technology!"

Wang Jiang shook his head and said: "We are designing an ultra-long-range, jet strategic early warning aircraft, and the several structures you said are not good and not suitable!"

"In the flowing gas, relative to the gas flow, the propagation speed of the weak disturbance is also a very severe test, in the flow field where the temperature T is not constant, the pressure at each point is different, when the temperature of the gas flow is very high (such as high overspeed flow), or there is an external excitation source, the kinetic energy of the internal vibration of the gas molecules is very large, and the dissociation degree of the molecules is very high. ”

"In this case, when a weak pressure wave sweeps through and the temperature of the gas changes very quickly, the translational and rotational energy of the gas molecules quickly reach the corresponding equilibrium!"

"However, the characteristic time required for the molecular vibrational energy and dissociation energy to reach the new equilibrium state is much larger, which increases the flight drag sharply, and the ratio of flight speed to pressure at 30 in space at this moment will reach more than 1/1000!"

"So this R18 accessory has to be tackled. Chief Engineer Wang's serious and unquestionable voice spread in the conference room.

"However, not to mention the accuracy now, even the material performance does not meet the requirements!"

"Then find a way to take it. Chief Engineer Wang said with bated breath: "We national defense workers, no matter what kind of difficulties can not fall, if it doesn't work today, then come tomorrow, if it doesn't work tomorrow, then the day after tomorrow, it will become one day, if we give up now, then everything we have done before will be in vain, just like the moon in the water." ”

"Okay, Chief Engineer Wang, I must find a way to take down R18!"

"Okay, if you have any questions, you can ask the organization for help, and I will explain this matter to the above!" Chief Engineer Wang nodded, and continued: "Let's talk about the second accessory ED857." ”

ED857: Abdominal ATA fusion device.

"In the design of the Kong-30 AWACS aircraft, a local fusion design with more optimized performance is also adopted between the supercritical wing and the engine, fuselage and hanging, which further improves the safety and practicality of the Kong-30. ”

"Although the design was designed with technical difficulty in mind, the overall difficulty was not much reduced, because the engine was installed close to the wing, and there was inevitably drag interference between the two. ”

That is, the pressure effect of "1+1<2", so that the resistance of the two together is less than the sum of the resistance of the two, and there are very high requirements for the strength and accuracy of the transition zone between the wing and the fuselage, which not only loses the lift of the wing, but also improves the lift coefficient of a part of the wing. ”

"We used the ATA hanging, which could not destroy the pressure distribution on the lower surface of the wing, nor the pressure distribution on the engine nacelle, and the fusion design was carried out on the leading edge of the wing, which allowed the wing to reach the stall safety boundary without destroying the pressure distribution, which improved the safety of the aircraft. ”

"Chief Engineer Wang, ED857: Belly ATA fusion device, the ruler pressure of the entire fitting reaches 1.2 meters wide, 1.7 meters long, and 1.5 meters high, this is not the most important, the most important ED857 also has various structures inside!"

"I also went to the C Research Institute and asked Director Rong to try that super machining center, but it was completely useless, and now the materials meet our requirements, but there is a very big gap in accuracy!"
