Great Power Technology.

Chapter 198 This Heart

The negotiations on the Nantianmen project team suddenly accelerated, but Ye Zhou didn't pay much attention to it. Chen Hao took care of this one. He only occasionally learned from the other party that he still didn't let go of the exchange conditions, even the technology transfer plan. There is not much increase in all digging and searching.

If the base cannot be built, there are actually two technologies that Ye Zhou wants. The first is the Tu 160 Big White Goose, and the second is the Belgorod nuclear submarine. One of the two is an aerial raptor, and the other is an underwater Behemoths are all good things that the country has been greedy for for a long time.

If it can be exchanged in the Nantianmen project, it is really not a big loss.

However, the other party obviously couldn't see the great significance of the Nantianmen project for the time being, so they didn't even think about bringing out this kind of state-of-the-art technology. They mentioned the big white goose, but the exchange conditions were very harsh. The project team cannot accept it.

Ye Zhou shook his head, dispelled his chaotic thoughts, and focused his attention on the test bench in front of him again.

GE-9X has completed the assembly of all components and entered the final stage of final assembly. In three days, it can enter the first ground test drive.

Within these three days, he will complete all inspections on the ground test platform to ensure that the test process goes smoothly and obtain accurate and precise data.

The problem of abnormal temperature of the fuel system discovered by Ye Zhou before has been solved. After a round of comprehensive inspection, it was finally found that the cause of abnormal oil temperature control was that the working voltage of the fuel pump was unstable, which led to abnormal pump oil volume, which led to abnormal temperature of the circuit.

This made Ye Zhou very thankful for his caution, because if this problem was allowed to slip by at that time, then during the ground test, the abnormal oil pump would not only cause abnormal engine operation and distortion of the detection data, but in severe cases would also cause serious damage to the engine. permanent irreversible damage to the engine.

If such an accident really happened, then this time the bridal sedan chair project would be far from perfect.

Looking at the staff who were busy checking the stand, Ye Zhou said:
"Try to tidy up the pipelines, check the tightening torque of the snap ring in advance, and measure the natural vibration frequency. I remember you said that this bench has not been tested after changing the supporting structure a few months ago. Today is just the right time. Measure it."

In fact, the test frequency control of the bench is based on the idle speed of the engine. The documents in the project team's hands do indicate the various parameters of the engine, but Ye Zhou can't guarantee the various parameters of the first engine produced. The index can really be consistent with the design drawing, so for the sake of safety, the natural frequency of the bench must be as low as possible.

"Understood, Ye Gong."

The staff just replied briefly, and then continued to invest in the inspection of the bench and pipeline.

Seeing how busy they were, Ye Zhou nodded slightly, and walked to the master control terminal beside him, and began to test the data collection and electrical system without load, especially focusing on the engine emergency stop protection function, after confirming that everything was ok , and then joined the team of other engineers to do the final inspection of the oil seal system with them.

At 8 o'clock in the evening, all the inspection work on the test bench was completed, and after confirming that there was no problem, Ye Zhou stuck in the last minute of his 10-hour working time and announced that he was off work.

The preparations for the ground test vehicle have all been completed, and the next step is to wait for the engine to leave the factory.

As long as the ground test is completed, it can be proved that the manufacturing of this engine is at least 60% successful, but this does not mean that this engine can be equipped and used immediately. After the data collection is completed, the engine needs to undergo a series of calibrations. Work.

At present, most of the major international aviation manufacturers use the standard engine transfer test calibration, which is the most accurate and most able to ensure the stability of the engine running state, but the problem is that the GE-9X manufactured by the sedan chair project is not There is no available base aircraft, so we can't temporarily transfer a Boeing 777 to dismantle the engine for calibration, right?

Therefore, the method Ye Zhou intends to adopt is mainly the calibration method of the measurement target. It will take a long time to do so, and there are certain problems with the accuracy, but fortunately, it can basically meet the standard.

While recalling the various data of the measurement method in his mind, Ye Zhou walked towards the engine assembly workshop. Under Chen Hao's strong request, all the staff have entered the 10-hour work system. There was a large wave of people coming off work, and they stood at the door and waited for a long time before the crowd passed.

When he finally walked into the assembly workshop, it was empty and there were no moving figures in sight.

In the extremely empty factory building, the lights in the distance gradually went out, only the huge high-pressure sodium lamp on the top of the engine still emitted a bright and cold white light, illuminating the most complex, sophisticated and industrial machine in the history of human industrial development. Aesthetic engine.

Its shell has not been painted yet, and the silver-gray surface presents a cold and strong character. The fan blades are neatly arranged in the air intake, like sharp blades, about to cut through those in front. Heavy, gray, suffocating air.

Ye Zhou walked around it involuntarily. He stretched out his hand to touch it, and was surprised to find that its surface wasn't icy cold, even compared to what he had already blown in the cold spring wind in March. Cold hands are warmer.

Probably a certain part of the pre-assembly process makes its temperature rise.

he thought silently.

Ye Zhou gently stroked the smooth surface of the engine, his movements were cautious, as if he was stroking an exposed heart, for fear that his actions would damage its fragile shell.

But in an instant, he felt that his thoughts were a little funny.

The casing of this engine is made of a new material whose strength is almost as strong as titanium alloy.

Thinking of this, Ye Zhou retaliated and tapped the shell lightly twice, and the deep sound echoed throughout the workshop, like a faint drumbeat from the chaos.

A scene from a comedy movie he watched a long time ago flashed through his mind. In that scene, a racing driver stroked the frame that had almost turned into scrap iron, closed his eyes and tried to feel the rhythm of the frame, and then Also said with emotion:
"Echoed."

Before today, he always thought this scene was ridiculous.

How can a human being communicate with a machine?
It was nothing more than a heap of manufactured goods, a heap of cold machinery of steel, and machinery had no emotion and no response.

But now, when he put his hand on the unfinished engine, he really felt that echo.

Nothing to do with machinery, nothing to do with steel, nothing to do with industry.

It was a very primitive, but eternal desire.

Longing for the sky.

A racer's frame is more than a frame because it's on the track.

And his engine is not just an engine.

Its journey is at an altitude of 1 meters, or even [-] meters.

This is a special life form, a life form that was forged in the form of heavy industry after condensing the wisdom and energy of several generations, and even condensing the blood of the predecessors.

Its role and significance are not just to send an aircraft over 150 tons into the sky, but to completely open a future that no one has ever experienced.

Yes, it is a heart.

Not only the heart of large aircraft, not even the heart of the aviation industry.

It is the heart of the great and grand cause of the entire Chinese nation embarking on the road to the stars and the sea.

It is, the heart of the dragon.
