That night he was arranged to stay in the factory guest house, and it was already past one in the morning when he went to bed.

I got up as usual the next day, and Yan Hang came over early in the morning with a young man.

I took him to the factory canteen and had a simple breakfast.

It has to be a large state-owned factory, but the whole factory is just like a small society.

All infrastructures are there. Although they are not as brilliant as before, the foundation is still there.

After breakfast, Yan Hang took him to the workshop where the engine was installed yesterday.

When he walked into the workshop, there were already a bunch of people standing in the workshop.

This group of people can be divided into two groups according to their hair color, one group has gray hair and the other group has black hair.

"Everyone, please be quiet. Let us welcome Mr. Li from the Nine Provinces Divine Beast for his strong support to us.

And in such a short period of time, the engine we will use was manufactured and delivered.

Everyone applauds.”

Just when he stepped into the workshop and walked in front of everyone, Yan Hang spoke to everyone.

Everyone present applauded, and the applause was very warm.

After the applause, Yan Hang did not waste too much time on this idle matter.

Instead, he directed people to unload the engine from the truck.

Eight engines are in the workshop, neatly lined up.

Everyone present felt excited. In their eyes, Li Zhenhua standing next to Yan Hang was magical.

In such a short period of time, the other party actually produced the engine.

And not only one model was produced, but two models were produced, eight units in total!

The arrival of the engine was a timely blessing for them. Without her engine, Hongdu would obviously have to buy a high-priced engine.

At this moment, Yan Hang looked at the eight engines in front of him in a daze, just because two engines were placed in front of him.

When it was delivered yesterday, it was too late and he couldn't see it clearly when the engine was reversing.

But now he saw clearly that there were two types, which disrupted his plan.

"Mr. Li, do you have two motives?"

Facing Yan Hang's inquiry, he said with a smile.

"Yes, there are two kinds. It also gives you a choice.

I was afraid that the engine I made would not be suitable, so I made two types.

And Mr. Yan, just call me Zhenhua!"

Yan Hang smiled after hearing this, but there was a hint of helplessness in his smile.

"Zhenhua, you really have a problem. We only thought it was a model at first.

So we have prepared one type of experimental stuff, and now that there is an additional engine, how should we experiment!"

At this time, he also knew what was wrong with the other party. It turned out that the other party was not prepared enough.

"Mr. Yan, it's my fault. I should have told you in advance.

I don’t know how many machines like this you have built. If there are many, then there will be no problem!

Aren’t we just flying into the sky together to experiment!”

After listening to his words, Yan Hang shook his head.

He had no idea that Li Zhenhua on the opposite side used this method to get the engine out.

"Zhenhua, this is not just a simple experiment like installing a machine and testing it for flight.

There are many aspects involved in this process. Let me think of a solution.

Which of these two do you like most? Let’s test which one first!”

After all, he was not an airplane manufacturer, and he didn't know much about the tests in between.

He has always followed the path of practice, and everything was tried out by him.

But Hongdu didn't dare to be like him.

After he mentioned the engine he was optimistic about, he didn't care about anything else. Anyway, Yan Hang and the others would have a headache.

Yan Hang thought for a moment and called an old man over.

"Lao Zhou, you have also seen that there are two engines on site, and we only prepared one for the experiment.

So I’ll leave this to you while I go get another set of things needed for the experiment.”

After Yan Hang finished explaining, he spoke to Li Zhenhua and left directly.

The new old man was not polite to him, he just pulled him and walked towards the engine.

Then, under the command of Lao Zhou, everyone at the scene started to move in an orderly manner.

Installing the engine on the aircraft is not just about installing it;

This process requires many tests. Lao Zhou first installed the engine on the test bench and tested it.

Then came a series of tests that he couldn't understand. After all, he was just a man of action.

These theoretical things are really not what he is good at.

He followed Lao Zhou and answered Lao Zhou's questions about the engine.

At the same time, he was also absorbing the knowledge from Lao Zhou and others in manufacturing airplanes.

The two of them were like this, you learned from me and I learned from yours, and the day passed quickly.

For him, this day was fulfilling and he learned a lot of knowledge, but for Hongdu Factory, it was a busy day.

In the next few days, various tests were carried out on the engine.

And on the next day, the test of another engine also started.

Yan Hang also wants to know which of the two engines is more suitable.

Today, the test on the 1.2L unit finally ended, and the data obtained are gratifying.

With these data, the Hongdu factory will also proceed to the next step, installation!

There are two planes parked not far apart in the workshop.

These two aircraft are prototypes used for verification, and the engines will be installed shortly.

Everyone pushed the engine and walked towards a plane.

Arriving next to the plane, amidst the busyness of everyone,

The originally empty engine compartment of the aircraft was filled with engines, and there was still a large gap in the cabin.

After the engine was installed on the aircraft, some things that did not match the engine were changed and the engine was adjusted to its optimal condition.

Once the airplane has an engine, the airplane becomes complete and everything is ready.

Now only the test flight is left. As long as the test flight is completed, the aircraft will be truly completed.

After another two days, Yan Hang’s application for a test flight of the aircraft was finally approved.

There are some white clouds floating in the sky, the sky is very blue, and the weather is very good. It is a very suitable weather for the test flight.

Li Zhenhua also followed Yan Hang to the test flight ground early in the morning. Logically speaking, this test flight was not something he could watch.

But who makes him the supplier of the engine? He can also know whether there are any shortcomings in the engine after watching the test flight.

The test pilot this time was still Lieutenant Wang. After the last test flight, he already had an understanding of the model in front of him.

Lieutenant Wang saluted in front of the temporary tower and walked towards the plane.

Everything was ready, and under Li Zhenhua's watch, the plane successfully left the ground and flew into the blue sky.

According to the senses of Lieutenant Wang who was flying the plane, this plane was obviously more comfortable than the last time he flew it.

After replacing the engine, the aircraft has experienced a qualitative improvement in all aspects of its performance thanks to the enhanced thrust.

Just when Li Zhenhua was still holding his head high and staring at the plane in the sky,

Lieutenant Wang's voice came from the speaker nearby.

"Tower, tower, birdie applies for maximum ceiling test."

After getting permission from the ground, Lieutenant Wang in the sky flew the plane towards higher airspace.

This time the power was sufficient, and the engine-limiting button on the instrument panel was nowhere to be seen.

The plane flew towards higher airspace at a large angle, and the strong power carried the plane to high altitudes.

Soon Lieutenant Wang changed the plane to level flight, and this time he reached an airspace of 6,500 meters.

The aircraft flew in the sky again for a while and conducted many tests at this altitude.

On the runway, the plane was landing. After taxiing for a certain distance, it stopped.

The engine stopped, Lieutenant Wang jumped out of the plane and walked quickly towards them.

I saw Lieutenant Wang standing opposite Yan Hang, saluting him and answering.

"Report, test pilot Wang Zhifei successfully completed the mission."

Yan Hang patted Lieutenant Wang on the shoulder, and a bright smile appeared on his face.

"How does Mr. Wang feel this time?"

"I think this time I feel very good, very good, this time the momentum is very strong, not weak at all.

I think this is enough for a civilian aircraft.

Although I haven’t flown too many civilian aircraft, this aircraft gives me the most comfortable feeling, especially because the noise is handled so well.”

Lieutenant Wang's words of praise for the aircraft were endless.

At this moment, Li Zhenhua finally felt relieved, knowing that his engine was successful.

And according to the test pilot, he was very satisfied with the power of this engine.

Just when he was stunned, Yan Hang came towards him with the test pilot.

"Zhenhua, let me introduce to you, this is today's test pilot, Wang Zhifei."

After that, he said something to Lieutenant Wang.

"I told you before, this is Li Zhenhua, the manufacturer of the engine. You guys talk first, and I'll go take a look at the plane."

After Yan Hang finished speaking, he walked towards the plane, leaving only the two of them still where they were.

Li Zhenhua stretched out his hand towards Wang Zhifei opposite.

"Hello Comrade Wang, are you satisfied with the power of the aircraft? Do you have any comments?"

After the two shook hands, Wang Zhifei told him his opinions.

"There is no problem with the power. I just want to see if the turbine can be redesigned.

In my driving experience, the turbine intervened too late at the beginning!

That’s the only drawback.”

It was not that he had not considered the problem Lieutenant Wang mentioned, but it was not easy to solve.

This turbine intervention lag is a common problem of this device. When the exhaust gas volume is insufficient, the turbine cannot activate, which is the main reason for the lag.

But this problem is not easy to solve. He had come up with a countermeasure before,

But this would require adding another device, so he didn't add anything to the engine.

He nodded to Lieutenant Wang and said.

"I know this problem. I will specifically solve this problem later. I will definitely be able to solve it later."

The two chatted about the plane for a while, and then Lieutenant Wang went to Yan Hang's place.

For a whole day, everyone stayed here at the test flight ground. Li Zhenhua also learned about the engine through discussions among the people present.

During the one-day test flight, the safety of this aircraft was recognized by the people present.
Chapter completed!
