Turboshaft D engine application model design finalization, the application is Li Tianfeng personally went to the capital to run, the application is relatively smooth, Li Tianfeng returned to Songzhou not long after, the relevant departments formed a turboshaft D engine model qualification examination committee.

This is a temporary committee, composed of relevant experts who are temporarily drawn from various relevant departments, and will be disbanded after the validation process is completed.

Li Tianfeng has been paying close attention to this matter, this engine model is qualified, which means that the design is finalized, and a special type certificate has been issued.

A new type of aero engine, from the beginning of research and development to mass production, generally to obtain three certificates, the first certificate is the type certificate, is issued for the design of aero engine, to prove that the design of aero engine meets airworthiness standards and certain technical standards.

The second certificate is the production license, which is issued specifically for the manufacturer, which proves that the manufacturer's quality system is sound and can ensure that the qualified products that meet the airworthiness standards are continuously produced under its quality system.

The third certificate is the airworthiness certificate, which is for a single aero engine, which is equivalent to the driving license of the car, as we all know, every car will have a driving license, and each engine also has an airworthiness certificate. Some large domestic aviation enterprises have airworthiness representatives stationed in them, and each engine is produced, and the airworthiness representative will issue the airworthiness certificate of this engine.

Generally speaking, the airworthiness certificate of the first aero engine is more difficult, and the joint review of the expert group and relevant departments is required, such as the turboshaft D engine of Tianfeng Technology Company, the airworthiness certificate of the first official engine must be jointly reviewed, and the airworthiness certificate of the subsequent engine is relatively easy after the review is passed.

It's a bit far, let's get down to business. A few days after Li Tianfeng returned to Songzhou, the review committee composed of experts from relevant departments was formed, and began to review the information submitted by Tianfeng Technology.

In the office. Li Tianfeng was answering the phone.

Zhang Hongzu said: "Mr. Li, our model review committee has completed the review of relevant information, and is expected to arrive at your company tomorrow, which will review the actual engine, as well as your quality management system, technical standards, etc." ”

Li Tianfeng knew that there were seven relevant experts on the review committee, and he was very fortunate that Zhang Hongzu was the leader of the expert group and Zhang Haiping was the deputy leader.

Originally. When he saw the list of members of the expert group, Li Tianfeng felt a light in his heart, the main and deputy team leaders are all his old acquaintances, and this time the engine model qualification should be a sure thing.

Sure enough, when the expert group finished reviewing the materials, although it was very careful, it was still smooth. Li Tianfeng is relatively clear about his own information, and there is definitely no big problem. But if people want to find faults, how can they find some faults.

But this time the data review was basically smooth, and only two inconsequential minor problems were listed, and Li Tianfeng knew that Zhang Hongzu and Zhang Haiping must have helped him.

Li Tianfeng smiled and said, "Lao Zhang." Welcome to Tianfeng Technology Company. ”

Zhang Hongzu smiled happily, it was completely different from Yan Sù when he came to Tianfeng Technology Company last time for review, and after laughing happily, Zhang Hongzu said a lot of things to Li Tianfeng on the phone, including what information needs to be prepared. What aspects need to be paid attention to, Zhang Hongzu said in detail.

Li Tianfeng humbly wrote them down one by one, although Li Tianfeng also knew these things more clearly, but his attitude was still very modest, and he agreed and wrote them down one by one.

Li Tianfeng said: "Lao Zhang, I will come to pick you up in person tomorrow morning." ”

Zhang Hongzu said: "Mr. Li, there is no need to be so polite, just arrange a car to pick us up outside the airport, you don't need to come in person." ”

The two chatted on the phone for more than half an hour, and after the call ended, Li Tianfeng thought in his heart that the expert group would arrive in Songzhou tomorrow morning, and some things needed to be arranged now, especially the reception, at least to be polite.

So, Li Tianfeng called Xu Lilong over and instructed some things, especially the reception, tomorrow morning, Xu Lilong personally took the car to the airport to meet the expert group.

After arranging these things, soon after, Li Tianfeng received a call from Zhang Haiping, and the two chatted for a long time on the phone.

The next day, the team arrived as scheduled.

According to Li Tianfeng's request, Xu Lilong personally went to the airport to pick everyone up, and the convoy drove from Songzhou Avenue and stopped at the gate of Tianfeng Technology Company.

At the gate, Li Tianfeng has already been prepared, and the huge banner "Warmly welcome all experts to visit Tianfeng Technology Company to guide the work" has been pulled up early, and Li Tianfeng is even more with everyone, standing at the gate of the factory to greet everyone.

In addition, the number of security guards on duty at the gate today is at least twice as large as before, and everyone is wearing neat security uniforms, full of spirit, standing neatly and neatly, and lining up to welcome the presence of experts.

The convoy stopped, Xu Lilong was the first to get off, and then, Zhang Hongzu, Zhang Haiping, a total of seven experts, everyone also got off the car one by one.

Li Tianfeng smiled warmly, hurriedly greeted him, stepped forward, held Zhang Hongzu's hand tightly, and said happily: "Team Leader Zhang, welcome, welcome!" ”

Zhang Hongzu said: "Mr. Li, it's too polite, come, I'll introduce you." ”

Zhang Haiping naturally didn't need to be introduced, the two were very familiar, Li Tianfeng and Zhang Haiping shook hands, the two understood and smiled at each other.

The remaining five experts, from several departments, Zhang Hongzu introduced Li Tianfeng one by one, Li Tianfeng warmly shook hands with everyone one by one, and they came to audit, although Zhang Hongzu and Zhang Haiping are his old acquaintances, but Li Tianfeng's polite kung fu is very well done.

After everyone shook hands one by one, Li Tianfeng introduced several people from his side to everyone one by one, including Sun Kang, Qiu Wen'an in design, Sun Xiaoping, Zeng Qinghai in craftsmanship and others.

After a polite greeting, Li Tianfeng took everyone to the office building, and everyone followed, except for Zhang Hongzu and Zhang Haiping, the remaining five people in the expert group were all coming to Tianfeng Technology for the first time.

When I was in the capital, everyone was already familiar with Tianfeng Technology Company, but this familiarity was only limited to relevant information, and it was the first time to really come to Tianfeng Technology Company.

Walking into Tianfeng Technology Company, seeing such a magnificent factory gate, I saw the spacious and straight eight-lane main road in the factory, which is hundreds of meters long and almost invisible at a glance.

When they saw the magnificent technology center and the huge modern factory buildings, these experts basically quietly exchanged glances, and even two or three people nodded gently.

It is worthy of being able to develop such an advanced and excellent turboshaft D engine, this hardware condition is not ordinary, such a scale and grade, the investment is at least more than 10 billion!

Before walking into the office building, we looked around from time to time, and when we saw such conditions and such factories, we couldn't wait to go to the production sites immediately to take a good look.

What is the specific situation of this company? What are the advanced machine tools, what are the advantages in technology, why they can develop such an advanced engine in just two or three years, these experts who came to Tianfeng Technology for the first time, everyone is full of curiosity.

However, it is already more than 11 o'clock in the morning, and it is obviously impossible to go to the major factories in the morning.

Li Tianfeng enthusiastically led everyone, went to the office building, entered the reception room that had been prepared a long time ago, warmly beckoned everyone to sit down, drink tea, eat a little fruit, and chat a little.

Looking at the time, it was already past twelve o'clock in the morning, and it was time to eat, so Li Tianfeng stood up and said enthusiastically: "Everyone, we have prepared a light meal, and everyone will go to have a working meal together." ”

The meal must be eaten, Zhang Hongzu is the team leader, and he will arrive immediately: "That's okay, let's eat a little at noon and start working in the afternoon." ”

Li Tianfeng has already prepared a place to eat, next to the beautiful Songzhou Reservoir, the small farm courtyard with a very good environment, a total of two tables, a group of seven people, plus the relevant personnel of Tianfeng Technology, the two tables are just full.

Although it is a working meal, the dishes are very rich, sixteen dishes per table, very rich, considering that I have to work in the afternoon, I did not put on liquor, but on a little drink and beer.

At the dining table, the atmosphere was warm, and after the meal, everyone returned to Tianfeng Technology Company.

In the afternoon, mainly to visit the entire Tianfeng Technology Company as a whole, Li Tianfeng personally took the expert group to the workshops, and even went to the assembly workshop and the test workshop.

The major processing workshops of Tianfeng Technology are in full swing, and the workers are processing parts in their own positions.

Each plant, are more than 10,000 square meters, all kinds of machine tools and equipment are very complete, and there are a lot of imported equipment, the members of the expert group, all are insiders, or how can they be called experts, everyone's eyes are very powerful.

Enter each workshop, at least turn around, take a little look, you can see the extraordinary things about this workshop.

"Mr. Li, this is an imported German CNC broaching machine!"

"This is an imported high-precision five-axis linkage CNC machining center!"

"Mr. Li, this is imported vacuum heat treatment equipment!"

“……”

Every time they see a valuable imported equipment, the experts will be slightly surprised, and Li Tianfeng enthusiastically introduces this equipment to everyone one by one.

It didn't take long to watch it, and the experts kept nodding their heads, obviously, they had a good impression of Tianfeng Technology Company.

One of the experts, when he saw a worker processing a part, couldn't help but stop and look, and then glanced at the processing card on the work table, his eyes seemed to be fixed, and he couldn't take his feet off for a long time.
