Great Power Technology

Negotiations among the Nantianmen project team suddenly accelerated, but Ye Zhou did not pay too much attention. Chen Hao handled this area. He only occasionally learned from the other party that they still did not relent on the terms of exchange, and even the technology transfer plan There is not much overweighting in Douche Sosou Di.

If a 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 them is an aerial raptor, and the other is underwater. Giant beasts are all good things that the country has been craving for for who knows how long.

If it can be exchanged in the Nantianmen project, it really won't be a big loss.

However, the other party obviously cannot see the huge significance of the Nantianmen project for the time being, so they have never thought about coming up with such a nationally important technology. They did mention the Big White Goose, but the exchange conditions were very harsh. The project team couldn't accept it.

Ye Zhou shook his head, dispelled the chaotic thoughts, and refocused his eyes on the test platform in front of him.

The GE-9X has completed the assembly of all components and has entered the late final assembly stage. In three days, it will be ready for its first ground test.

Within these three days, he must complete all inspections of the ground test bench to ensure that the test process goes smoothly and that accurate and precise data is obtained.

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

This makes Ye Zhou particularly grateful for his caution, because if he had allowed this problem to pass by at that time, during the subsequent ground test, the oil pump abnormality may not only cause the engine to work abnormally and distort the detection data, but in serious cases will also cause damage to the engine. Permanent and irreversible damage to the engine.

If such an accident really happens, then this sedan project will be far from perfect.

Looking at the staff who were busy inspecting the bench, Ye Zhou said:

"The pipelines should be organized as neatly as possible, 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 since the support structure was changed a few months ago. Today is the day. Measure it out.”

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

"Understood, Ye Gong."

The staff simply replied and continued to inspect the benches and pipelines.

Seeing them busy, Ye Zhou nodded slightly, walked to the main control terminal on the side, and began to test the data collection and electrical system without load, especially focusing on the engine emergency shutdown protection function, after confirming that everything was OK. , and then joined the team of other engineers and worked with them to conduct the final inspection of the oil seal system.

At 8 o'clock in the evening, all the testing work on the test bench was completed, and after confirming that there were no problems, Ye Zhou announced that he was leaving get off work at the last minute of his 10-hour working day.

The preparation work for the ground test has been completed. Next, it is time to wait for the engine to officially leave the factory.

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

At present, most of the major international aviation engine manufacturers use standard engine transfer experimental calibration. This is the most accurate and most stable calibration method that can ensure the stable operation of the engine. However, the problem is that the GE-9X manufactured by the sedan project is not at all If there is no available mother aircraft, we can't temporarily transfer a Boeing 777 to dismantle the engine and calibrate it, right?

Therefore, the method Ye Zhou plans to use is mainly the calibration method of measurement standards. This takes a long time and has certain accuracy problems, but fortunately it can basically meet the standards.

While recalling various data on metrology in his mind, Ye Zhou strolled towards the engine assembly workshop. In the past few days, under Chen Hao's strong request, all staff had entered a 10-hour work system. Ye Zhou happened to bump into it when he passed by. There was a large crowd of people coming off work, and they stood at the door and waited for a long time until the crowd passed.

When he finally walked into the assembly workshop, it was empty, with no moving people 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 this most complex, most sophisticated, and most industrial machine in the history of human industrial development. Beautiful engine.

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

Ye Zhou couldn't help but walked around it again and again. He stretched out his hand to touch it, and was surprised to find that its surface was not cold. In fact, it was even colder than the surface he had blown in the cold spring breeze in March. The cold hands are even warmer.

Probably a certain link in the pre-assembly process caused its temperature to rise.

He thought silently.

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

But in an instant, he felt that his idea was a little funny.

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

Thinking of this, Ye Zhou lightly hammered the shell twice in retaliation. The low sound echoed throughout the workshop, like a faint drum sound coming from the chaos.

A scene from a comedy he had seen a long time ago flashed through his mind. In that scene, a racing driver was stroking the frame that had almost become scrap metal, closing his eyes and trying to feel the rhythm of the frame, and then He also said with emotion:

"It's echoed."

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

How can humans interact with machines?

It's just a bunch of industrial products, a bunch of cold machinery made of steel, and machinery has no emotions and will not respond.

But now, when he put his hand on the engine that had not yet been completed, he really felt the response.

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

It is an extremely primitive but eternal desire.

Desire for the sky.

A racer's frame is more than just a frame because its journey is on the track.

And his engine is not just an engine.

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

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

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

Yes, it's a heart.

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

It is the heart of the far-reaching and magnificent cause of the entire Chinese nation embarking on the road to the stars and the sea.

It is, the heart of the dragon.
