Siheyuan: Originally I just wanted to be a little transparent

Chapter 252 But, there is no if in this life
After taxiing, the Fifth Master, driven by Lin Shengli, successfully rose into the sky.

For Lin Shengli, who is proficient in airplane piloting, driving this Fifth Master is as easy as eating and drinking.

However, in order to reassure everyone on the ground, Lin Shengli did not perform any dangerous operations.

The fighter plane was flying very smoothly at this time. Lin Shengli scanned the right half of the fuselage with his flat glasses and found no problems for the time being.

According to the test pilots, this resonance occurred during the rapid climb of the fighter plane.

After Lin Shengli was ready, he called the tower on the ground, "Tower, tower, this is the No. 2 test aircraft. It is currently flying in good condition and no problems have been found. Please raise it quickly."

"The tower has received it and allows the lift to be raised. Please pay attention to safety."

"Roger that!"

After a skillful and beautiful pull-up, the plane piloted by Lin Shengli entered a stage of smooth flight again.

During the initial pull-up process, Lin Shengli could clearly feel the vibration on the right side of the aircraft. The faster the pull-up speed, the stronger the vibration.

Lin Shengli glanced at it with his plain glasses and quickly discovered the problem.

In order to verify the accuracy of this question, Lin Shengli once again conducted a quick pull-up flight.

Lin Shengli was flying freely above. The people below were extremely nervous at this time. They raised their ears and listened carefully to the sound of engines in the air. As long as there was nothing wrong with the sound of the plane's engines, it meant that No problem landing on the plane.

After confirming the specific location of the problem, Lin Shengli contacted the tower: "Tower, tower, this is test aircraft No. 2, requesting return."

"The tower received it, everything on the ground runway is normal, and return is allowed."

More than 20 minutes earlier than originally expected, Dean Tang finally received the news that Lin Shengli requested to return. He immediately ordered the commanders on the ground to quickly agree to return.

At the same time, Dean Tang and others also left the tower and came to the runway, waiting for Lin Shengli.

On the ground, everyone can already see clearly how Wu Ye flies in the sky, but at this moment, everyone's hearts are lifted up, because everyone knows that this It is during the process of taking off and landing that aircraft are most prone to dangers and problems.

When flying smoothly in the sky, under normal circumstances, there will be no problems unless you encounter some extreme airflow, but the probability of encountering that situation is extremely small.

The Fifth Master driven by Lin Shengli slowly landed on the wide runway. The fuselage began to contact the ground steadily, making a faint sound of tire friction.

Lin Shengli was in constant communication with the tower via radio to ensure that there would be no conflicts or dangers during the landing.

Wu Ye's landing gear slowly compressed, absorbing the impact during landing. The braking system was precisely controlled by Lin Shengli, causing the plane to decelerate smoothly on the runway.

During Wu Ye's landing, Lin Shengli paid close attention to the speed and attitude of the aircraft to ensure that the aircraft remained in a stable state.

After a period of taxiing and feeling a slight bump, the plane stopped steadily on the runway.

Every step of the landing touched the hearts of the people on the ground. When they saw the plane stop smoothly, many people jumped up waving their clothes.

Although the chance of something going wrong with this sick Fifth Master is only [-]%, this [-]% chance is the mortality rate. For a person, it means life or death. The test!

"Director Lin, please slow down."

After the plane stopped, Lin Shengli thought about jumping out quickly, but before the door was fully opened, anxious Lin Shengli hit the door with his helmeted head.

Seeing that Lin Shengli was in such a hurry, the ground crew quickly helped Lin Shengli get off the plane.

After getting off the plane, Lin Shengli hurriedly said to the staff on the opposite side: "Quick, dismantle it quickly. It's on the back half of the right wing. That's where the problem lies..."

Although Lin Shengli's voice was not loud, it was enough for those present to hear clearly.

When everyone heard Lin Shengli's words, they couldn't help but admire him. He was indeed an expert from Sijiu City. He flew up and found out the specific problem immediately.

It's not like they haven't studied the wing of this aircraft, but they had almost thoroughly studied the wing before, but in the end, they still didn't find anything wrong.

"Comrade Shengli, have you really found it?" Dean Tang asked loudly.

"Director Lin, please tell me, what's the problem?" Chief Engineer Lu also asked hurriedly.

Facing the two people's inquiries, Lin Shengli said, "The specific reasons for Dean Tang and Chief Engineer Lu, I will tell you in detail later."

"General Engineer Lu, please quickly organize people to remove the rear half of the right wing of the first Fifth Master."

Although Chief Engineer Lu was eager to know the reason, he temporarily suppressed his thirst for knowledge and quickly organized people to dismantle the wings of the Fifth Master's aircraft in accordance with Lin Shengli's request.

"Here, and here, yes, right here, remove all these rivets. Slowly, don't touch the gasket at the back." Lin Shengli directed the staff and nervously dismantled them.

After the several places designated by Lin Shengli were demolished, Lin Shengli said to Dean Tang and everyone present: "Dean Tang, you see, the problem lies here." Lin Shengli opened his palms, and in his palms, It's a few slightly scratched gaskets.

The location of this gasket is on the inside of the wing. It is used to connect the rear part of the fastener and the part that fits the fuselage. Most people will not notice it at all.

If Lin Shengli hadn't had the blessing of plain glasses, he wouldn't have been able to detect the data anomaly there.

"Director Lin, are you sure that it is this small gasket that causes the resonance of the aircraft?" Director Feng looked at the gasket in Lin Shengli's hand with some disbelief.

Lin Shengli nodded: "Basically, we are inseparable. Didn't I just ask Chief Engineer Lu to dismantle the wings of the Fifth Master's aircraft?"

"After comparing it with the one on the fifth master later, I can basically be 100% sure."

"Then what are you waiting for? Let's go to the hangar." Upon hearing this, Dean Tang quickly pulled Lin Shengli into the car and rushed to the hangar where the other Fifth Master was parked.

When Lin Shengli and the others arrived at the hangar, the right wing of the first Fifth Master had also been removed. Lin Shengli directed the staff to remove the same few gaskets at the same position.

After placing the gaskets at the same position on the two Wuye aircraft on a tool table, Lin Shengli scanned them with his flat glasses and immediately confirmed the real problem.

Lin Shengli pointed to several gaskets that looked exactly the same from the outside and said:

"Everyone knows that when our fighter jets fly at high speed, air shock waves will produce a lot of resistance. In addition, the front and rear pressure difference will produce a pressure resistance, and there will be a lot of resistance between the nose, wings and tail. Great compression force..."

"This gives our fighters a high chance of resonance."

"But at the end of the day, if the material is strong enough, there won't be any problems..."

"The cause of aircraft resonance is the material of this small gasket itself."

When Lin Shengli explained to everyone, everyone gathered around. After the last test flight of the Fifth Master, there was a problem and it was immediately sealed and never let it fly again.

This time Lin Shengli flew the Fifth Master, which was the second time it took to the sky while it was sick.

When everyone looked at the gaskets with obvious knock marks on Lin Shengli's left hand side, everyone felt a little regretful.

If they had known this was the case, there would have been no need for Lin Shengli to take the risk to fly around in the sky. They only needed to fly the Fifth Master one more time, and then come down. They would check it more carefully, and maybe it would work. Check it out!

However, there is no if in this life...

"That's the problem. Regarding the material field, I think everyone should be more professional than me, who is engaged in mechanics."

"So next, we have to rely on the big guys to do the work..."

Lin Shengli looked at the experts and professors surrounding him, and he knew that it was time for him to retreat.

He has already identified the problem, and the major credit is already his. As for how to solve the problem, it is left to these professionals.

After all, everyone has been working day and night to find out the resonance problem of this Fifth Master, and everyone has contributed a lot.

At this time, it's time for them to show off too.

Furthermore, in terms of materials, it is indeed his shortcoming.

In his "box" of books, there is very little content about basic materials.

It seems that his "box" of books may not be full, and it is estimated that it is only one-fifth or one-tenth of the books in a university library.

Factory Director Feng and the others didn't think so much. They felt that what Lin Shengli said made sense. It was not difficult for them to analyze the differences between these gasket materials. There was no need to keep dragging Lin Shengli to participate. .

Moreover, Lin Shengli has basically not had much rest in the past two days since he came from Sijiu City. This person has figured out the problem and it is time for him to take a rest.

Therefore, Director Feng handed over the task of analyzing the materials to these experts and professors headed by General Engineer Lu.

In fact, there is no need to conduct laboratory analysis or anything. Just replace the gasket on the first Wuye with the second Wuye and fly it a few times, and you can immediately detect whether this is the problem.

But there was no need for Lin Shengli to say this. Someone naturally raised this opinion.

So the second Wuye had the gasket replaced, and after several test flights, it was completely determined that the gasket was causing the resonance of the aircraft.

Lin Shengli's participation in the material testing and analysis of those gaskets is no longer needed. Lin Shengli's affairs with Nanfei have come to an end for the time being.

Lin Shengli had some other work to do in Workshop [-] of the steel rolling mill, and he couldn't stay with Nanfei forever.

So, under the warm farewell of everyone at Nanfei, Lin Shengli and Dean Tang returned to Forty-Nine City.
