Scholars in the courtyard

When Mr. Qin saw the expressions of the people in the Third Machine Department, he showed a hint of pride on his face.

No one knew what the final product would look like before they saw it.

But when he saw the installed engine this morning, he was attracted by the things in front of him, and he kept making comparisons in his mind.

Seeing this situation now, he naturally understood the shock in everyone's heart.

Yang Xiaotao followed a few people to the engine that had been placed.

Without waiting for him to introduce the basic data of the engine, Director Wu, who had just met, ran to him immediately, and then looked here and there, and even put his head on it, as if he wanted to get in.

Mr. Zhang and Director Zheng and others also looked serious, looking around the engine again and again.

The whole area became quiet.

After a long time, Wu Zhe walked aside, his face flushed, not knowing whether it was because of the heat or tiredness.

At this time, Wu Zhe had already believed Director Zheng's judgment.

This is a very special engine, with a very novel design concept and idea.

And the changes brought about by this unique design made him very interested.

"Hello, Mr. Yang. I want to know the basic data of this engine!"

"And some of the designs in it, please forgive me for my ignorance!"

Wu Zhe came to Yang Xiaotao happily, like a different person, with a respectful demeanor.

He heard that all the designs of this engine were completed by the people in front of him alone.

At the beginning, he thought it was a rumor.

An engineer who has no experience in aircraft engine design wants to design it based on the experience of designing ordinary engines. It's just a dream.

You have to know that an aircraft engine has so many structures, so many parts, and involves various disciplines and various abilities. It is not something that one person can complete.

It takes a long time for a team to design an engine that meets the current situation.

Even some designs are outdated when they come out.

So he is skeptical about this argument.

He even thinks that someone is building momentum for Yang Xiaotao.

Just like the dry rice that produced 10,000 kilograms per mu many years ago.

But now, seeing this engine, he knows that he is wrong.

It's not that this engine is bad, and any engineer can make it, but it's too good, so good that engineers today don't have the ability to fake it.

Moreover, this engine is too different from the engines they know and have seen.

At first glance, it is not of the same system.

And this just shows that it was made by Yang Xiaotao!

"Director Wu, I brought the design drawings!"

Facing Wu Zhe's inquiry, Yang Xiaotao didn't say much, but asked Wang Hao, who was carrying a box behind him, to come forward.

Everyone's eyes were on the two of them, and then they looked at the wooden box.

Inside, of course, are the design drawings of the engine.

Wang Hao put the box on the ground and breathed a sigh of relief.

Nothing else, it's too heavy.

His arms were a little sore from carrying it all the way here.

But he didn't dare to relax, because it was full of drawings. Secretary Liu said when he came here that these things are the precious wealth of the machinery factory, and none of them can be lost.

For this reason, he also brought a few clerks to look at these design drawings.

Yang Xiaotao stepped forward to open the box, and then revealed the stacks of design drawings inside.

Wu Zhe was shocked when he saw this scene.

He thought that such a complex engine must be not simple.

But he never thought that there were so many designs.

This, what is this person's brain like!

After seeing this, Director Zheng and other engineers from the Third Machine Department also looked solemn.

They all knew how many design drawings they had.

There must be less than what is in front of them!

At this time, Yang Xiaotao patted the box, "Here are some of the design drawings, mainly the main body. The other accessories are still in the machinery factory. I was in a hurry and didn't bring them!"

"But these should be enough."

He took out the top folded design drawing, and then asked Wang Hao and Zhang Guanyu to step forward and open it.

After hearing this, everyone was speechless.

This, this is just a part!

They know how many design drawings they have. If they really take them out for comparison, it would be good if this box can be half full.

Wu Zhe was shocked when he heard this, and hurried to the design drawing to look at it carefully.

"This is the overall design of the HXJ-1 aircraft engine. This is the front view, and the one next to it is the side view."

"According to the original design, this engine has..."

Yang Xiaotao pointed to the design drawing and explained the design parameters of the engine. As for the actual data, it still needs to be tested.

Here, Yang Xiaotao was explaining the engine data to Wu Zhe, and on the other side, Old Xia accompanied Old Qin to the side. The three looked at the two engines with different expressions.

"Old Zhang, how is your test of this model?"

Old Qin nodded to the engine of the Third Machine Department that was being tested and asked.

At this time, Old Zhang's eyes were all on the engine of the machinery factory. When he heard what Old Qin said, he didn't turn his head, but just responded, "It's better than yours."

Old Qin was bored, and then walked to the side to watch everyone inspecting in an orderly manner.

After watching for a while, he looked at Wu Zhe and Yang Xiaotao who were excited.

Over there, the two were chatting enthusiastically, one asking and the other answering.

Both of them forgot what was in front of them and were completely immersed in their own world.

"Mr. Yang, the pressurization method you designed is really great. It compresses the air and then burns it to generate higher power."

"However, this requires a very high material for the turbine. How did you solve it?"

Wu Zhe's eyes lit up, and he couldn't leave the design drawings for a moment.

Yang Xiaotao said with some pride, "This material has been developed by our Alloy Research Institute. It is a new type of titanium alloy."

"As for the material of the combustion chamber, it is a high-strength titanium-rhenium alloy that is resistant to high temperatures and can complete the work under high speed and high pressure."

Yang Xiaotao briefly explained, and Wu Zhe became more interested in this engine.     "Director Wu, let's do the experiment as soon as possible."

Old Xia came to interrupt the two people's communication. If they were allowed to continue chatting, it would probably take three days and three nights.

Wu Zhe came back to his senses, and then smiled at Yang Xiaotao, "I almost forgot the main business."

"Ahem, I think there is no problem with this external structure. Next, let's test the two engines together."

Wu Zhe directly skipped the step of comparing the actual object with the design drawing. After all, the design drawing was made by others. What's the use of him finding that it doesn't match?

Yang Xiaotao nodded, and then everyone helped to put the engine next to the engine of the Third Machine Department.

Not long after, the two engines were inspected and entered the test bench.

"First item, check the engine intake fan."

Wu Zhe shouted loudly, and someone immediately came forward to turn the fan, and then someone reported the rotation situation.

"Fan No. 1, the rotor rotates normally, and the blades rotate without misalignment."

"Fan No. 2."

As the staff finished observing from a distance, someone immediately recorded the results.

"Check the shock absorption."

"Check the root situation."

As the inspections were carried out one by one, Wu Zhe and others became busier and busier.

Zhang Guanyu and researchers from the Third Machine Department also joined in to help.

Yang Xiaotao sat aside with Old Xia and the others.

However, none of them had the desire to chat, and they all focused on the experiment in front of them.

It felt like a student who handed in his paper and looked at the teacher on the podium for review.

They were afraid that the teacher would say that they failed the exam, and they were also afraid that the teacher would say that other students got full marks.

When the night fell, the routine inspection items were basically completed. Although it was just an ordinary inspection, Wu Zhe conducted it very seriously, and even the most ordinary inspection items were meticulous.

"Director Wu, let's stop here today!"

Looking at the time, it was already nine o'clock in the evening. Old Zhang stepped forward to stop the experiment and said to Wu Zhe.

The same was true for Old Qin and Old Xia. Everyone was waiting here and hadn't eaten dinner yet.

Wu Zhe realized that it was already very late, so he suppressed his excitement, nodded, and asked his men to suspend the experiment.

"Chief, let me tell you about today's preliminary inspection."

Coming to the side, Wu Zhe reported today's inspection as usual, but the specific data was not announced.

Yang Xiaotao was listening on the side.

"Today we conducted three major projects of the fan, twelve sub-items of inspection, and all the inspection items met the requirements."

"Both engines passed."

Wu Zhe did not say which one was better, but the people on the side clearly felt that Wu Zhe's eyes looking at the HXJ-1 engine became more fiery.

"Tomorrow we will conduct follow-up experiments, and it is expected to be completed within a week."

After Wu Zhe finished speaking, everyone breathed a sigh of relief.

Especially the people in the Third Machine Department, they were afraid to say that it was unqualified, otherwise their efforts would be in vain.

Of course, they were also afraid to hear that it was not as good as the machinery factory, because that would be very embarrassing.

Similarly, everyone in the machinery factory was relieved.

As long as it is qualified, it is good.

Zhang Guanyu even gently wiped the sweat from his forehead.

If Mr. Yang's design, which is so good, fails to pass, he will lose confidence in the future aircraft engine design.

Fortunately, Mr. Yang's design passed.

"Come on, Old Zhang, this place is close to your Third Ministry of Machine Building, you should treat us as a host."

Old Qin put down his worries and immediately urged Old Zhang to treat him to a meal.

Old Zhang was also happy and agreed.

Director Zheng asked people to go back and prepare.

Afterwards, Yang Xiaotao walked with Wu Zhe, and the two talked about the design concept of the engine, and then got in the car to the Third Ministry of Machine Building.

In the jeep.

Wu Zhe picked up the inspection record sheet and looked at it again, frowning slightly.

Xiao Sun, who was sitting next to him, saw Wu Zhe's look and asked curiously, "Director, these two engines are good, why are you still not happy?"

Wu Zhe looked up and looked around, and then sighed softly.

"Director, if you have something to say, just say it, and everyone will try to help."

The part-time driver said on the side, and the person in the co-pilot also agreed, "Yes, Director, if you have anything to say, just say it."

Seeing that everyone in the car was his own, Wu Zhe no longer held back.

"You think both engines are good, right?"

Several people nodded after hearing this.

Xiao Sun even said, "Director, these two engines may be different, but they both meet the requirements in our acceptance standards."

"Moreover, the standards we are implementing now are stricter than before, at least 30% higher."

After Xiao Sun finished speaking, everyone else nodded.

Some people even think that raising the inspection standard and still meeting the requirements is a success in itself.

Wu Zhe just shook his head when he heard everyone say this, "You think that the standard requirements have been increased and meet the design requirements of the aircraft, so you think that both engines are qualified, right?"

Several people did not speak, but the expression on their faces was like this.

Seeing this, Wu Zhe sighed in his heart.

"This standard is customized according to the aircraft."

"But have you ever thought that this standard only meets the passing line of the aircraft, not the limit of the aircraft!"

Hearing this, everyone in the car was silent again.

Wu Zhe turned over the test data. Whether it is the smoothness of the blade rotation or the rotation rate, the No. 2 engine has more advantages.

If you have to score the two according to the current standards, the passing line is 100 points, and both can reach 100.

The former passed, so it is 100 points.

But the latter is because it is only 100 points.
