Simulation: Great Power Technology

Ye Zhou and Chen Hao stayed until after lunch before leaving the sanatorium. Before saying goodbye to the old man, Ye Zhou held the written word in one hand and the old man's hand in the other, and made an agreement with him.

We must continue to persevere for 6 months. Even if we go to ECMO, we must see Qilian fly for the first time.

But in fact, everyone knows that the possibility that this agreement can be achieved is too small.

According to what Chen Hao explained to Ye Zhou after he left, in fact, it was a miracle that the old man could last for 3 days.

This is also the reason why Chen Hao called Ye Zhou in such a hurry.

After returning to Liming Factory, Ye Zhou did not tell Chen Hao much, but directly held a meeting of the core decision-making level of the sedan sedan project team. Evaluation before test drive.

After a professional evaluation by the test technical team, the final conclusion is that all the preparations are in place, and there is no need for redundant backup.

......

Qilian engine, the ground test countdown, 3 hours.

"Finally check the oil pump and pipeline, if there is no problem, you can start the system to warm up."

Ye Zhou stared nervously at the engine on the test bench. Now that all the preparations have been completed, as long as the final emergency procedure check is completed, the test can be started.

For 7 months, they worked day and night, and finally created the most complex product ever made in the history of China's aviation industry, which is about to face the big test.

As the engineers made the final overhaul, they whispered about the tests that were about to begin.

"Why do I feel so nervous, just like the college entrance examination before... No, I am more nervous than the college entrance examination now. From noon to now, my heart rate has not dropped below 100, and I feel like I am dying. ."

"Damn it, are you serious? If your heart rate is so high, then go to rest! It's really going to kill you?"

"Don't bullshit, you let me rest at this time? You might as well just ask my fate. Stop bullshitting, how is the temperature of the central fuel tank?"

"The temperature is stable, no problem. Check the connection of each pipeline and pull it hard. If it is not firm, quickly re-install it."

"I've already unplugged it, no problem. Is the electrical system circuit normal?"

"The circuit is normal, Ye Gong can already see the data."

"Is the thrust detection system working?"

"No problem, it has been reset to zero. I tested it just now, and the slide rails are working normally. The error of the measured thrust accuracy is between 1% and 2%."

"This error... is still a bit big. What if it almost doesn't exceed the ge-9x next door?"

"...Do you really think this is an exam? It doesn't matter, this is the first time we have built an engine with such a large thrust. Even if there is a slight difference, it is normal. Be normal."

"That being said, but people always have expectations... How high do you think the thrust can be?"

"60 tons is definitely stable, but the question is, after 60 tons, what is the stability of the engine? If the surge is serious, it is meaningless to even reach 70 tons."

"There is also the corrosion and wear of various components. We can blast 120 tons at a time without any problem, but when the thrust reaches 120, the combustion chamber will be blown up, which is completely bullshit."

"So, in addition to thrust, you have to look at stability."

"It should be no problem, manufacturing and assembly are strictly in accordance with the requirements..."

"Don't bullshit, oil and power on! Check the status of the oil system and start oiling the various components."

"Come on. The fuel supply line has also been checked, and now it is time to check the emergency fire protection system."

"The emergency fire protection system has been checked, no problem, Lao Xu, are the fire trucks in place?"

"Well, it's parked at the door. I don't think it will be used. The fire protection of our test stand is still very strong."

"Don't be afraid of 10,000, just in case... turn on the power."

The switch is pushed up, and the power system of the test bench is fully activated.

Ye Zhou took a deep breath as he looked at the green indicator light that gradually lit up in front of him.

The moment has finally come.

This is the most important moment for an engine, and it is also the first and most important test that determines whether it can get on the plane or not.

As long as this test can be passed, it means that the initial goal of the sedan chair project is basically achieved.

After that, the official launch and official use are actually just some finishing work that takes time to grind.

This is like a sword. After the most critical blade is made, although it will still take a lot of time and energy on the scabbard, hilt or other accessories, as long as the blade is born, the sword will be already done.

All the core members of the sedan sedan project team have all come to the monitoring area of ​​the test bench, and their expressions are equally nervous.

After a countdown of 30 minutes, the final cleaning of the test bench was completed and the engineers began to evacuate.

"Ye Gong, do you want to say something?"

Someone in the crowd in the surveillance area suddenly asked.

Ye Zhou was stunned for a moment, but did not answer immediately.

Say something? According to the practice of this kind of large-scale project, before the final result is accepted, it is indeed necessary to talk about something. For example, the comrades have worked hard during this period of time. We are very tired but have achieved outstanding achievements. For example, as long as the acceptance is successful, , I will give everyone a big bonus, such as what breakthrough progress we have made, and everyone's name will remain in history in the future.

and so on.

But at this moment, Ye Zhou couldn't say it at all, and he didn't want to say these words.

This is something that everyone already knows. What is the significance of saying it again?

After a moment of silence, he said:

"This is the first big test of Qilian Engine, and it is also our first big test."

"Although we have made great efforts in the early stage, as long as it is an exam, there is a possibility of failure."

"If there is a problem with the next test drive, I just want to say one thing to everyone: don't be disappointed, don't give up."

"We have done many things that our predecessors could not imagine. Even if we fail, it means that we have once again moved a boulder on the road to the sky."

"So, it's all worth it."

"But of course, I hope, everything goes well."

After that, Ye Zhou turned to the engineer who was waiting for the operation and said:

"Go ahead, start the engine!"

The voice fell, the engineer pressed the button, pushed the joystick, and a low wind noise sounded on the test platform below.

The engine started smoothly, the turbofan began to rotate at a speed of thousands of revolutions per second, and a hot air stream was sprayed from its rear, and the air in the workshop was instantly distorted.

Ten minutes after the steady idle state, Ye Zhou gave an instruction to increase the power.

The operating lever continued to be pushed up, the fuel supply speed increased, the thrust of the engine suddenly increased, and the wild roar like a giant dragon swept the entire factory in an instant!
