Chapter 203 Test drive start
Ye Zhou and Chen Hao stayed until after lunch before leaving the nursing home. 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 persist for 6 months, even if we go to ECMO, we must see Qilian make his first flight.

But in fact, everyone knows that the possibility of this agreement being fulfilled is too small.

According to what Chen Hao explained to Ye Zhou after leaving, in fact, it is already a miracle that the old man can survive for 3 days.

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

After returning to the Liming Factory, Ye Zhou did not tell Chen Haoduo, but directly held a meeting of the core decision-makers of the sedan chair project team. There was only one topic of the meeting, that is, based on the completion of the preparatory work, the Qilian engine should be carried out. Evaluation before test run.

After the professional evaluation by the test run technical team, the final conclusion is that all the preparatory work has been completed, and no redundant backup is required. The engine test run is ahead of schedule, and the first test run is scheduled for 6 pm on the same day.

Qilian engine, ground test countdown, 3 hours.

"Check the oil pump and pipeline for the last time. 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 preparatory work has been completed, the test run can start as long as the final emergency procedures are checked.

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

Engineers are doing final overhauls while discussing in low tones the tests that are about to begin.

"Why do I feel so nervous, just like I used to take the college entrance examination. No, I am more nervous than the college entrance examination now. From noon to now, my heart rate has never dropped below 100. I feel that I am dying."

"Damn, are you serious? If your heart rate has been so high, then go to rest quickly! Will it really kill you?"

"Stop talking nonsense, you let me go to rest at this time? You might as well take my life and forget it. Stop talking, what's the temperature of the center fuel tank?"

"The temperature is stable, no problem. Check the connection of each pipeline, pull it out hard, and quickly reconnect if it is not firm."

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

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

"Is the thrust detection system working properly?"

"No problem, it has been reset to zero. I tested it just now, the slide rail works normally, and the accuracy of the thrust measurement error is between 1% and 2%."

"This error is still a bit big. What if it almost misses the GE-9X next door?"

"...Do you really think this is an exam? It doesn't matter. This is the first time we have produced such a high-thrust engine. Even if there is a little difference, it is normal. Be normal."

"That's what I said, but people always have expectations. How far do you think the thrust can go?"

"60 tons is definitely stable, but the question is, how stable is the engine after 60 tons? If the surge is serious, it doesn't make sense to even reach 70 tons."

"There is also corrosion and wear of various components. We can push 120 tons at a time without any problems, but if the thrust reaches 120 tons and the combustion chamber is burned, it is completely bullshit."

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

"It should be fine, the manufacturing and assembly are strictly in accordance with the requirements"

"Don't talk about it, turn on the oil and power! Check the status of the oil system and start to lubricate the various components."

"It's on. The oil supply pipeline has also been checked, and now we are checking the emergency fire protection system."

"The emergency fire protection system has been inspected, no problem, Lao Xu, is the fire engine in place?"

"Here, it's parked at the door. I guess it won't be needed. The fire protection of our test bench is still very strong."

"If you're not afraid of [-], you're afraid of power failure."

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

Ye Zhou looked at the green indicator light that was gradually lighting up in front of him, and took a deep breath.

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 be used on an airplane and what kind of engine it can be used on.

As long as it can pass this test, it means that the initial goal of the sedan chair project has been basically achieved.

Afterwards, the formal use of the computer is actually just some finishing work that takes time to grind.

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

All the core members of the bridal sedan chair project team have come to the monitoring area of ​​the test platform, and their expressions are equally tense.

With 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 monitoring area suddenly asked.

Ye Zhou was taken aback for a moment, but didn't answer right away.

What can I say?According to the practice of this kind of large-scale project, before the final results are accepted, there is indeed something to say, such as comrades who have worked hard during this time, we are very tired but have achieved outstanding achievements, for example, as long as this acceptance is successful , I will give everyone a big bonus, such as what kind of breakthroughs we have made, and everyone’s names will remain in history in the future.

And so on.

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

This is something that everyone already knows, so let’s say it again, what’s the point?
After a moment of silence, he said:
"This is the first big test of Qilian Engine, and 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 are problems in the next test run, 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 huge rock to the road to the sky."

"So, it's all worth it."

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

After all, Ye Zhou turned to the engineer waiting for the operation and said:

"Go ahead, start the engine!"

After the voice fell, the engineer pressed the button and pushed the joystick, and a low-pitched wind noise sounded on the test bench below.

The engine started up smoothly, and the turbofan began to rotate at a speed of thousands of revolutions per second. Fiery air flowed out from behind it, and the air in the workshop was instantly distorted.

After 10 minutes of steady idling, Ye Zhou gave an order 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 dragon swept across the entire workshop in an instant!
