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

"Buzzing..."

With the huge airflow from the propeller, the dead branches and leaves around the tarmac were blown to all directions!

Immediately afterwards, three straight-five aircraft slowly landed on the tarmac.

After the plane landed steadily, Zhou Yang led Gu Chenghua, Fan Debiao, Gao Tingye and others to greet it immediately.

The cabin door opened slowly, and Gu Zhenhua and others got off the plane one after another!

After seeing Gu Zhenhua, Zhou Yang said a little excitedly: "Oh, I finally waited for you, it's not easy!"

"Hahaha, it's really not easy. After receiving the order from the superior, I thought I could leave early, but I didn't expect it to be delayed for another month!" Gu Zhenhua said.

"It doesn't matter if you are late, as long as people come!" Zhou Yang said with a smile.

After a simple exchange of pleasantries, Zhou Yang took Gu Zhenhua and others back to the research institute.

Since it was just eleven o'clock, and there was still an hour before lunch, Zhou Yang brought everyone into the meeting room, planning to have a simple meeting to get to know each other.

In the meeting room, there are many people, and the atmosphere is harmonious!

After the two parties sat across the conference table, Zhou Yang got up first and said, "Hello everyone, everyone present here includes my old friends and unfamiliar faces, so I will briefly introduce myself here!"

"My name is Zhou Yang, and I am the director of the Babaoliang Research Institute. Our research institute is directly under the Equipment Department. It is a first-level research institute dedicated to the research and design of aviation radar and aircraft..."

Before the words fell, many people in the working group showed shocked expressions.

They didn't expect that there was a first-level research institute hidden in this mountain corner, and the director of this research institute was so young.

You know, even if you look at the number of first-level research institutes in the country, it is very rare, and even some provinces do not have a first-level research institute in the whole province.

Zhou Yang also saw the expressions of these people, but he didn't explain too much, but said again: "We will all work together for a long time in the future. In order to facilitate communication and exchanges with each other, everyone Let me briefly introduce myself, let’s start with our research institute!”

Hearing Zhou Yang's words, Gu Chenghua was also unambiguous, and immediately got up and said, "Hello, everyone, my name is Gu Chenghua, and I am the deputy director of the research institute and the person in charge of security!"

"Hi everyone, my name is Fan Debiao, and I'm the director of the security department of the research institute!"

"Hi everyone, my name is Liu Yunlong, and I am the Director of the Personnel Department of the Research Institute..."

.......

Soon, the comrades at the Babaoliang Research Institute finished introducing themselves, and then it was Gu Zhenhua's turn.

As the leader of the working group, Gu Zhenhua got up immediately and said: "Hello everyone, I am Gu Zhenhua, an aircraft designer from Liaoshen Aircraft Factory. I am very happy to work with you!"

As soon as the words fell, a middle-aged man next to Gu Zhenhua stood up and said, "Hello everyone, my name is Liao Xingyun, and I am the deputy chief designer of the Helicopter Research Institute..."

Before he finished speaking, Gu Zhenhua added: "Comrade Liao Xingyun is an expert in the field of helicopter research in our country, and the straight six that will be mass-produced is due to him!"

Liao Xingyun hurriedly said: "Brother Zhenhua puts the hat on for me a bit too high, how dare I call myself an expert in front of you guys, hahaha!"

Afterwards, another middle-aged man beside Liao Xingyun also got up and said, "Hi everyone, my name is Huang Zheng, and I am an ordinary designer at Changzhou Aircraft Manufacturing Factory. I am here with a learning attitude this time!"

"Hi everyone, I'm Wang Xinhao..."

After everyone had introduced themselves, Zhou Yang said again: "We have invited you here this time. We have only one purpose, and that is to research and design a helicopter that is more advanced than the straight-five and straight-six. Only less than a year away!"

As soon as these words came out, everyone was dumbfounded!

They knew about the research on helicopters from the very beginning, but it was only a year, which really caught them by surprise.

"Comrade Zhou Yang, how can one year be used? Aircraft design is an extremely rigorous matter. It takes more than half a year for a single conceptual design stage. It is good to complete the design demonstration in one year. The design drawing is already extremely fast, and it is almost impossible to complete the overall design within one year!"

Perhaps because he felt that what he said was a bit too much, Liao Xingyun said in a calm tone: "I am not questioning everyone's ability, just take the straight six that has just been finalized for mass production. It was designed in 66 and made its first flight in 69. , It took two years before and after."

"It took 9 years from the first flight to mass production. From design to mass production, the overall time is 11 years. Even if you have design experience in straight-six, it may not take five or six years. It’s hard to finish this project too!”

Huang Zheng on the side also echoed and said: "Old Liao is right. Aircraft design should not only pursue speed, especially in the conceptual design stage. This is the key to the overall layout of the aircraft. It must be carried out in depth, meticulously and carefully to avoid future accidents. due major repetition."

"Yeah, one year is too short, at least three to five years!"

"Who says no, I think five years is a bit short..."

Listening to everyone expressing their opinions and opinions, most people think that it is impossible to develop an advanced helicopter in a year.

Zhou Yang didn't refute it either, and when everyone had said the same thing, he looked at Gu Zhenhua and said, "Old Gu, tell me your opinion?"

Gu Zhenhua smiled and said: "If others say this, I really think it's unreliable, so I have to get up and refute it!"

"But it's a different matter if the words came out of your mouth, Zhou Yang. I don't think it's a big problem!"

Hearing this, Liao Xingyun, Huang Zheng and others were all stunned, and then looked at Gu Zhenhua in surprise.

Gu Zhenhua said with a smile: "Don't look at me like this, if you know Comrade Zhou Yang's record, you won't have this expression!"

Since it involves military secrets, he did not say the following things.

But the more this happened, the more surprised Liao Xingyun and others were.

They didn't know Zhou Yang, but they knew Gu Zhenhua's character, and knew that he was not the kind of person who would like to be flattered.

If so, there must be a reason.

In addition, he became the person in charge of a first-level research institute at such a young age. For a while, everyone couldn't help but whisper to each other, discussing Zhou Yang.

"cough!"

After coughing lightly, Zhou Yang said again: "Thank you, Gu, for your trust. The reason why I am confident to complete the development task of the new helicopter within one year is mainly due to two reliances!"

"What do you rely on?"

"The first is that we have completed the research in the conceptual design stage, and provided the three-sided diagram of the helicopter, the overall layout of the helicopter, the center of gravity positioning map, the weight and center of gravity calculation report of the whole helicopter, and the flight performance calculation report, etc.!"

"Om..."

Everyone was taken aback by Zhou Yang's words, including the people from the Babaoliang Research Institute. They didn't know when Zhou Yang completed the concept design of the helicopter.

Others find it even more inconceivable. The concept design stage of the aircraft involves too much content. Any mistake may cause major problems in the aircraft, so this is the most time-consuming part of the entire design.

If Zhou Yang and the others had really completed the concept design, it would really save a lot of time.

At this time, Zhou Yang's voice came from everyone's ears again: "Next, you only need to continue to carry out the external load calculation report, the preliminary analysis report on the structural bearing capacity of the whole machine, and the preliminary technical requirements of each component and system, etc., and we will be able to proceed. The next stage of design, and ordering various parts for machine assembly..."

Before Zhou Yang could finish speaking, Liao Xingyun frowned and said, "Director Zhou, this procedure is not right. Shouldn't we have to wait for the higher-level department to review the report after we have produced it?"

As an expert in helicopter research, Liao Xingyun is very clear about the various procedures and steps of aircraft design. After the conceptual design is completed, the next step is to carry out preliminary design and detailed design. After passing the above technical review, it will enter the trial production stage.

If this process is faster, it will take two to three years, and if it is slower, it will take four to five years.

After the trial production is completed, there will be a long test flight, and mass production will be finalized without any major problems, and the waiting time will be even longer.

It was also because of this that Liao Xingyun and the others did not believe that they could complete the design task of the helicopter within one year. If nothing else, they might not even be able to pass successive audits by their superiors in one year.

Then, Zhou Yang's next answer made everyone present completely dumbfounded...
