A mountainous area, Dawn Motivation Manufacturing Company.

16o hours have passed, and from the moment the blade is assembled on the motor to the present, it has been running on the test bench for seven days and seven nights.

This motive blade is said to have been made from high-purity titanium by the 8O9O1 Division (code name for the Six Shields of National Defense). Dean Wu had the leaves tested. The hardness and toughness are indeed better than the ordinary blades, and the purity of titanium is infinitely close to 1oo%, reaching 6 9s.

Dean Wu immediately became interested, asked the workers to bring a domestic Thai mobile machine, replaced the blades, and began to test.

……

The Thai mobile machine is a high-thrust engine that began in the eighties of the last century, took 18 years to develop, and began to be put into service in batches in 2oo5, and is used to equip the third-generation fighters, with a maximum thrust of 132oo kg and a thrust-to-weight ratio of 7.8, which is the most advanced domestic motive in H country.

The thrust of the motive is not only related to the construction of the motive, but also to the material strength of the blades.

In the three high environments of high temperature, high and high pressure, the motor blades are subjected to unimaginable pressure, and after a long period of use, metal fatigue will occur, and once it fails, it will face huge risks and losses.

The so-called metal fatigue is related to the purity of the material. For example, in the process of use, the fluctuation of trace components will lead to extremely unstable mechanical properties of titanium alloys. The disturbance of some impurities will cause great changes in the internal structure of titanium metal, such as cracks and thrust declines, which will seriously affect the service life of the motor.

In the past, the purity of domestic titanium alloys was not enough, and some of the motor blades produced could only be used for tens or hundreds of hours. The average life of the first batch of Thai mobile aircraft produced in O5 was only less than 2oo hours, and after serving the Air Force, there were many failures and returns.

More than 10 years have passed, and the manufacturing technology of domestic motives has made great progress. It is said that the latest S-1OC Thai mobile aircraft. In a maintenance cycle, the service life has reached 2ooo hours, and the thrust-to-weight ratio is 8, although there is still a gap with foreign countries, but it has reached the standard of mass service troops.

……

At the beginning, after the 88 blades were assembled on the engine, there was a bang. The test bench shook violently, and the thrust exceeded 13o thousand N in an instant, and Dean Wu thought that he was dazzled, and the engine did not turn on the afterburner? Why did the thrust become so big.

He asked the assistant to open the afterburner chamber, turn on the afterburner mode, boom! There was another violent tremor. The instantaneous thrust broke through 155 kN.

How is this possible? The maximum ultimate thrust of the domestic Taixing, that is, 135 kN, how can it be possible to change a set of blades, and the thrust has increased by 2o kN out of thin air?

"Intensify the test and carry out the ultimate test!"

"Extreme testing? Old Wu, what should I do if my motive is broken? ”

"As long as the limit of this blade can be measured, the motive will be broken!"

"Yes!"

Wu Zhengchun has been in this business for more than 4o years. From a student, to a technician, an engineer, a deputy chief designer, and then to an academician. There are more than 1o models of motivation that he participated in the development, but he is not satisfied with each one, and even feels ashamed. The source of this shame, for no other reason, is that the thrust is too small, compared with the most advanced motives abroad. Whether it is thrust or service life, there is no comparison at all, and they are not worthy of lifting shoes.

The most fundamental reason is the backwardness of material manufacturing technology, which restricts the development of the entire industrial system.

Dean Wu saw hope in these blades, and that department could get 88 high-purity titanium alloy blades out at a time. That means you can take out 888 pieces, 8888 pieces, or even 80,000 pieces! This means that in the near future, every motor will be fitted with such blades. Improve the overall performance of motivation.

What he wanted to confirm now was whether this blade was real.

For seven days and seven nights, the engine was almost falling apart after being shaken off, and the thrust was still hovering around 13o thousand newtons, and in order to maintain this thrust, the engine had to burn 2 tons of fuel per hour.

2 tons of aviation fuel, equivalent to 30,000 yuan.

More than 5oo burned out, but Dean Wu was not distressed at all, but became more and more excited, more and more happy, he even only slept 4 hours a day, and whenever he was free, he came to the scorching motivation test workshop to record the number of jù. Looking at the pure blue cone-shaped tail flame, I was stunned, and what flashed in my eyes was endless anticipation and hope.

Rumble! The roar of motivation came to an abrupt end.

"Oh no, Old Wu, the motive is parked!"

"Is it a matter of motivation or a problem of the blade?" Dean Wu grabbed the man's hand and asked.

"I don't know, this can't be seen until the motive cools down."

"Hurry up, then!"

After 3 hours, 88 blades were removed, and although the exterior was charred as carbon by the flames, their strength was not much changed from before.

The workers carefully held these blades and said to Dean Wu: "Old Wu, do we still want to do a test run?" ”

"Do! Change the engine and then do it, and then do a stress test for a week, if there is no problem with these blades, apply to the above, and purchase this kind of blade in large quantities, we want 1,000 pieces, 10,000 pieces! ”

Everyone is stunned, you know, the pressure test is not better than the ordinary test, the material under this test condition, there will be ten times, dozens of times the life loss, these 88 pieces of motor blades can last 16o hours of continuous use, indicating that the actual service life has reached more than 5ooo hours.

If it lasts for another week, the actual service life of this blade is more than 1oooo hours, there is no doubt.

Liming Company produces its own motive blades, and it would be good to be able to last 78 hours, Dean Wu ......

"Don't be stunned, hurry up and change!" Wu Zhengchun yelled at them.

"Yes!"

……

After a few days of thinking, Tianming finally came up with the idea of making netbsp in batches; Director Qiao applied for 150,000 yuan from the Finance Section, saying that he wanted to buy 25oo CPUs, 7oo solid-state drives and a certain number of GPU chips from outside, and let the strangers help their department build a level of computers.

In less than 1o minutes after the application report was typed, 15o million was hit on the financial card of the Cybershield Bureau, and the efficiency was the same as in the past.

The people in the finance department are not fools, what is the supernatural? The supernatural is the golden rooster that can lay golden eggs! In the past six months, accountants have now seen their recent capital expenditures plummet, reaching a surprising level.

Many high-precision parts in the tens of thousands, hundreds of thousands or even hundreds of thousands. You don't need to buy any of them, they can be mass-produced. Hundreds of thousands, millions of tons of high-purity rare metal materials, as long as tens of thousands of tons of low-purity materials are purchased outside to replace, and the ability can help purify.

15o million level computers, cheap is almost as cheap as cabbage! Accountants even think it's a little unreal, is there really a 15o level computer?

After the payment, the accountants counted it a little. The funds saved in this half month have been accumulated with a daily limit of 5oo.

I heard that the higher-level leaders are already discussing the matter of raising the salaries of the staff in the base, and the current discussion is not the question of whether to add more, but the question of how much to increase.

……

Closer to home, the method of manufacturing CPUs in bulk is actually quite simple. That's the 'bud bed growth method'.

Tianming used a 16-in-1 netm as a template and coupled it with another monocrystalline silicon wafer without transistors to make an inverse template with billions of small holes. In this way, with this reverse template, every time you want to produce a new CPU, you only need to stick a monocrystalline silicon wafer to the reverse template. The transistors are then pulled out of the grooves of the template to generate transistors one by one.

In this way, a new CPU is made.

In the same way, solid-state drives, GPUs, memory modules, and backbone circuit control chips. Nothing can stump Tianming, he only spent one Saturday overtime to produce 2ooo CPUs, 6ooo SSDs and other hardware components, which is amazingly efficient.

Three days later, when he came to the Cybershield Bureau, Tianming asked the staff who were nervously assembling the computer: "When will the computer be assembled?" ”

"It's coming. Just wait a little longer. ”

Two hours later, in each large cabinet, a motherboard with a CPU or SSD was placed on each floor, and the sides were connected by wires and network cables, forming a part of the huge computing center.

Power on, load drivers, and install the operating system. It lasted three days. This class computer with 2ooo CPUs, 4oo GPUs and 6oo SSDs was successfully built.

"Let's start testing the arithmetic!"

The programmer opens a piece of testing software and starts testing the floating-point arithmetic of the calculation.

The recorder reported: "The peak operations are 8oo trillion operations per second, and the flat peak operations are 75o trillion operations per second. CPU utilization rate is 49%, GPU processing degree is 12O trillion times, and utilization rate is 67%"

Computer engineer Gu Gong frowned and said, "Why is the utilization rate of CPU and GPU so low?" Something went wrong. ”

The Chang Gong next to him seemed to understand something, and muttered: "I heard Comrade Stranger say that he has improved the accuracy and performance of the netm level, but the performance of other parts of the hardware is far from being able to completely wave out the performance of these CPUs, that is to say, these CPUs are too advanced!" Naturally, it was dragged back. ”

Gu Gong also nodded, agreeing with this statement, and at the same time looking forward to the day when he would be able to maximize the performance of these CPUs.

"Start porting the game Simulation Space!"

"Download progress 1%, 2%...... 1oo% transplant successful! ”

Ye Xiaobai successfully transplanted the virtual game to this computer with a storage space of up to 1246TB.

Put on the helmet and click on the game to start, this game is easy to run and go to the virtual world after a lap. Ye Xiaobai asked Tianming, who was waiting on the sidelines, to experience the new virtual world.

The pure space, the green meadow, the crisp birdsong, and the faint fragrance of flowers make it seem like entering a real world.

"What's wrong with this virtual world from the last time? It seems to be 1o times bigger! ”

"Brother Xu, my next goal is to expand this virtual world to 64 square kilometers within a month, and load a fun game in it."

"What game?" Tianming asked curiously.

"You'll know then, and I'll have a few new helmets ready so we can go inside and play together, and I'll teach you how to play that game."

"Okay, remember to let me know when the time comes."
