The negotiations with Mao Xiong on the Nantianmen project team suddenly accelerated, but Ye Zhou did not pay much attention. Chen Hao handled this area. He only occasionally learned from the other party that Mao Xiong still did not let go of the exchange conditions, and even the technical transfer plan was stingy and not much increased.

If the base cannot be built, Ye Zhou actually has two technologies. The first is the Big White Goose in Tu 160, and the second is the Belgorod nuclear submarine. One of these two is the raptor in the air and the other is the underwater beast. They are all good things that I don’t know how long it has been greedy in China.

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

However, the other party obviously could not see the great significance of the Nantianmen project for the time being, so they had never thought about taking out this kind of national-level technology. They mentioned the Big White Goose, but the exchange conditions were very harsh and the project team could not accept it.

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

The ge-9x has completed all the components assembly and entered the late stage of the final assembly stage. In another three days, you can enter the first ground interview.

Within these three days, he had to complete all inspections of the ground interview bench to ensure the smooth test process and to ensure accurate and precise data were obtained.

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

This made Ye Zhou particularly glad for his caution, because if this problem was allowed to slip through, then during the subsequent ground interview, abnormal pump oil may not only lead to abnormal engine operation and distortion of detection data, but also cause permanent irreversible losses to the engine in severe cases.

If such an accident really occurs, the sedan project this time will be far from perfect.

Looking at the staff busy checking the bench, Ye Zhou said:

"Try to keep the pipeline neatly as close as possible, check the tightening torque of the snap ring in advance, and measure the inherent vibration frequency again. I remember you said that this bench has not been tested after changing the support structure a few months ago, and it happened to be measured today."

In fact, the test frequency control of the bench is based on the engine's slow speed. The documents in the project team do indicate the various parameters of the engine, but Ye Zhou cannot guarantee that the indicators of the first engine made can really be consistent with the design drawings. Therefore, to be on the safe side, the natural frequency of the bench must be as low as possible.

"I understand, Master Ye."

The staff simply replied and continued to investigate the bench and pipelines.

Seeing them busy, Ye Zhou nodded slightly, walked to the general control terminal beside him, and began to test the data collection and electrical system without load, especially focusing on testing the engine emergency parking protection function. After confirming that everything was fine, he joined the team of other engineers and worked with them to conduct final inspection of the oil seal system.

At 8 pm, all the testing work of the test bench was completed. After confirming that there was no problem, Ye Zhou announced his return to get off work at the last minute of the 10-hour working time.

The preparations for the ground interview drive have been completed, and the next step is to wait for the engine to officially leave the factory.

As long as the ground interview is completed, it can be proved that the engine has been manufactured at least 60%, but this does not mean that the engine can be equipped and used immediately. After the data is collected, the engine will also undergo a series of calibration work.

Currently, most of the standard engine transmission experimental calibrations adopted by the International Aviation Engine Factory are standard, which is the most accurate and most capable of ensuring the stable engine operating state. But the problem is that the Ge-9x manufactured by the Huacai project has no available mother machine at all. You can't temporarily adjust a Boeing 777 to dismantle the engine calibration, right?

Therefore, the method Ye Zhou intends to use is mainly the calibration method of the metrology target. This takes a long time and there are certain problems with accuracy, but fortunately, it can basically meet the standards.

While recalling various data from the metrology method in his mind, Ye Zhou walked towards the engine assembly workshop. In the past few days, under Chen Hao's strong request, all staff members had entered the 10-hour working system. When Ye Zhou passed by, he happened to run into a large crowd of people who were getting off work. He stood at the door and waited for a long time before waiting for the crowded crowd.

When he finally walked into the assembly workshop, it had become empty and there was no sign of activity.

In the extremely empty factory, the lights in the distance gradually faded, and only the huge high-pressure sodium lamp on the top of the engine still emitted a dazzling and cold white light, illuminating the most complex, most precise, and most industrially beautiful engine in the history of human industrial development.

Its shell has not been painted yet, and the silver-gray surface presents a cold and hard and strong characteristic. The fan blades are neatly arranged in the air inlet, like sharp blades, about to cut through the solemn, dark, and suffocating air in front of them.

Ye Zhou couldn't help but walk around it around it, and he reached out to touch it, and then was surprised to find that its surface was not cold, and it was even warmer than his hands that were already blown coldly in the chilly spring breeze in March.

Perhaps it is a certain link in the pre-assembly process that causes its temperature to rise.

He thought silently.

Ye Zhou gently stroked the smooth surface of the engine, and his movements were cautious, as if he was stroking a naked heart, fearing that his movements would destroy its fragile shell.

But in a flash, he felt his thoughts were a little funny again.

The shell of this engine is made of new materials with a strength of almost the same as titanium alloy.

Thinking of this, Ye Zhou blew his shell twice with revenge, and a low sound echoed throughout the workshop, like a faint drum sound coming from chaos.

A scene of a comedy that he had watched a long time ago suddenly flashed through his mind. In that scene, a racer stroked the frame that had almost become scrap metal, closed his eyes and tried to feel the rhythm of the frame, and then said with emotion:

“It’s back.”

Until today, he had always thought this scene was ridiculous.

How can a person echo the machine?

It was just a pile of industrial products, a pile of cold machinery made of steel, and machinery had no emotions and would not respond.

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

It has nothing to do with machinery, steel, and industry.

It was an extremely primitive, yet eternal desire.

Desire for the sky.

Racing drivers’ frames are more than just frames, because their journey is on top of the track.

And his engine is not just an engine.

Its journey is above an altitude of 12,000 meters or even 20,000 meters.

This is a special living body, a living body that condenses the wisdom and energy of generations, and even the blood of its predecessors, and then is cast through the form of heavy industry.

Its function and significance are not just about sending an aircraft of more than 150 tons to a high altitude, but about completely opening up a future that no one has ever experienced before.

Yes, it is a heart.

Not only the heart of large aircraft, but 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 sea of ​​stars and seas.
