Rebirth 1975: Tore up the call-back order at the beginning

The meeting in the conference room of the machinery factory is still going on, and the atmosphere in the venue is still dignified!

However, just as the factory leader was making the final summary, the door of the conference room was suddenly knocked open.

The huge movement immediately attracted everyone's attention!

Immediately afterwards, under the stunned eyes of everyone, Gu Zhenhua, the leader of the aircraft design team, rushed in directly, and then said excitedly: "I understand...I understand..."

Seeing his mad state, the director of the factory, Director Zou, immediately got up and asked, "Old Gu, what's wrong with you, what do you understand?"

"I understand the reason for the aircraft's transonic buffeting!"

Hearing this, everyone in the venue was shocked, and everyone stood up.

Director Zou also asked in shock: "Did you really find the reason?"

"Found...found..."

Then Gu Zhenhua said loudly: "The design team and the engineering team quickly follow me and gather at the No. 2 assembly workshop, hurry up!"

After speaking, he ran outside with a frenzied expression.

And everyone in the meeting room was dumbfounded, it's a meeting now!

For a moment, everyone's eyes were fixed on Director Zou on the stage.

Director Zou's reaction was also very quick, and he immediately said to everyone: "It depends on what I do, hurry up and follow!"

The sky is big and the earth is big, and the project is progressing the most. In comparison, what is a meeting that is about to end!

After receiving the instructions from the factory leader, everyone in the conference room reacted immediately, and then ran outside in a swarm.

After the design team and engineering team had almost left, Director Zou said to several deputy directors around him: "Looking at the appearance of Lao Gu, he should have really found the cause of the failure, let's not wait here Alright, let's go see it too!"

"Row!"

Afterwards, several factory leaders also left the conference room one after another and rushed to the assembly workshop!

Soon, the main cadres of Songling Machinery Factory were all concentrated in the aircraft assembly workshop.

At this time, next to the J-[-] fighter plane parked in the center of the workshop, Gu Zhenhua was analyzing the cause of the plane's transonic buffeting for the staff around him.

"It's almost like this. Due to the insufficient design of the fuselage, when the aircraft flies above the speed of sound, the airflow diversion area will cause the fighter to vibrate..."

After listening to Gu Zhenhua's explanation, someone immediately asked: "Leader, since the cause has been found, how should this problem be solved?"

"Partial remodeling!"

Then Gu Zhenhua pointed to a part of the side of the plane and said: "My idea is to modify the angle of this part of the plane to change the flight streamline and flow field of the plane, so as to achieve the purpose of eliminating buffeting!"

"This is a good idea, let's add it up and see if it works!" said Wang Dayu, the deputy head of the design team.

"Okay, let's argue now!"

"Calculate now..."

Soon, the results of the demonstration by the design team came out. The local modification method can indeed change the flight streamline and flow field of the aircraft, and it is very likely to solve the problem of aircraft buffeting.

Gu Zhenhua is a man of action. He immediately instructed the comrades in the engineering team to carry out repairs on the parts on both sides of the plane.

Since the changes are not very large, the amount of work is not very large, and it only took a few hours to complete the work.

After finishing, although the surface of the plane looks bumpy, the big guys always feel that the lines are smoother.

Immediately, Gu Zhenhua couldn't wait to ask the factory leaders for instructions to conduct a test flight immediately!

Director Zou and the others were also anxious. After receiving the request from Gu Zhenhua and the others, Dang even agreed to their request.

........

Songling Machinery Factory. Proving ground!

Although it was already past three o'clock in the afternoon, and it would be dark in less than two hours, the test site was full of people inside and out.

In addition to the comrades from the design and engineering teams of the aircraft, all the middle and high-level leaders in the factory came, plus comrades from the ground support, tower command and other departments, a total of [-] to [-] people participated in the flight test.

Looking at the slightly dilapidated fighter planes on the runway in the distance, everyone was very excited, but more anxious.

The same fighter plane, the same proving ground, they don't know how many similar experiments have been conducted.

As a result, the problem of body shake has not been resolved.

So right now everyone is also a little worried, whether this experiment will end in failure like before.

However, compared to everyone's uneasiness, Gu Zhenhua was very confident.

They have never been able to find the reason for the transonic chattering of fighter jets before, which has caused this problem to remain unresolved.

After reading the reminder from the mysterious designer today, he immediately understood the crux of the problem, and he believed that it would be possible this time.

"Team leader, the pilot is ready, ask for instructions to take off!"

"Agreed to take off!"

Following Gu Zhenhua's order, the J-[-] fighter jet on the runway glides across the runway under the control of the test pilot, and then soars into the sky with a very beautiful head-up.

Soon, the plane lost its shadow from everyone's sight, and only the staff of the ground command center could search for the fighter plane through radar.

Immediately afterwards, the ground command center received a flight status report from the pilot from the air: "Report: The aircraft is in good condition, azimuth...altitude...speed...please give instructions!"

At this time, Gu Zhenhua said in a deep voice: "Order: increase the speed to the speed of sound, and fly at transonic speed!"

"Yes!"

As the order was issued, everyone's hearts rose to their throats.

The previous dozens of experiments stopped here every time.

Whenever the speed of the aircraft increases to the speed of sound, the fuselage will shake, and they cannot eliminate it no matter what method they use.

Success or failure depends on one action, everyone is very nervous!

However, when everyone was nervously waiting for the result, the pilot's exclamation suddenly came from the microphone: "Report: The fuselage is not shaking...no shaking!"

Hearing the pilot's report, the ground command center was silent for a few seconds, and then cheers burst out!

However, Gu Zhenhua forced himself to calm down, and said again: "Order: Conduct the transonic flight test again!"

"Yes!"

Soon, the ground received another report from the pilot: "Report: The plane's speed exceeds the speed of sound, the fuselage is stable, and there is no sign of shaking!"

Gu Zhenhua was relieved after getting the pilot's reconfirmation.

At this time, a group of factory leaders also surrounded him, surrounding him.

"Old Gu, you are really good at it. You said in the morning that you will definitely be able to solve the problem, and it will be done in the afternoon. It's super fast!"

"Gu team leader, good job, you solved such a big problem for us this time, the factory must give you credit for your superiors!"

"Yes, this gong must be requested..."

However, at this moment, Gu Zhenhua suddenly said in an astonishing way: "Leaders, you may have misunderstood. The problem of aircraft buffeting was not discovered by me..."

Before the words fell, Director Zou said immediately: "Who else can you have, we all see it, do you want to give the credit to the big guys again, this is not possible..."

Before Director Zou could finish speaking, Gu Zhenhua said eagerly: "It's really not this time. By the way, leaders, I have something very important to report to you!"

Seeing that Gu Zhenhua didn't look like a fake, Director Zou immediately said: "Okay, then let's go back to my office and talk about it!"

"Row!"

After the group arrived at the factory director's office, Gu Zhenhua explained in detail the confidential documents he received from the equipment department in the afternoon.

After listening to Gu Zhenhua's report, Director Zou said with a look of shock: "You said that someone from above sent an improvement plan for the J-[-]B fighter jet, which mentioned the problem of transonic buffeting of the fighter jet?"

"Yes, I thought that plan was just a gimmick for the designer to please the public, but now it seems that our vision has narrowed, and the other party is a real genius in aircraft design!" Gu Zhenhua said with a sigh.

"Do you know that the research institute came up with that plan? What's the name of that genius designer?" Director Zou asked in a deep voice.

"I checked the signature, it's the Babaoliang Research Institute, the name of the designer is not mentioned!"

"Babaoliang Research Institute, who of you know what kind of research institute this is?" Director Zou immediately asked several other factory leaders.

However, everyone was at a loss, obviously not aware of the situation of this institute.

At this time, Gu Zhenhua suddenly said: "Leader, I want to contact this talented designer through the equipment department. I think his understanding of J-[-] may have surpassed any of us!"

"As long as he is willing to help us, our J-[-] fighter jets will probably be finalized in advance and deployed in the troops!"

Director Zou immediately said: "Okay, I'll contact you. If it's possible, you, Gu, go meet him in person!"

"Row!"

After speaking, Director Zou immediately called the equipment department...
