Regarding the type certificate for this electric aero engine, Huang Xiru actually went to the national civil aviation department to apply for it in person as early as a week ago, and the application was relatively smooth. Although this electric aero engine is not a fuel-fired engine in the traditional sense.

aircraft engine.

However, it is not without precedent. For example, the engines used by most drones are powered by electricity. However, since they are drones, they do not need to be approved by the civil aviation department for a type certificate.

Therefore, not long after Huang Xiru returned, the relevant departments established an review team for the electric aircraft engine type certificate.

Like the previous one, this is a temporary review team composed of relevant experts who are also temporarily transferred from various relevant departments. However, due to the particularity of electric aero engines, this review team has been added to this review team that have not been included in the previous model certificate review team.

Experts in electromagnetic power.

Of course, since this is a temporary group, after the electric aero engine is reviewed, this group will also follow us, and these experts will return to their posts.

And Zhang Yi is also very concerned about this matter. After all, if it passes the review, then this electric aviation engine will be finalized and can be mass-produced.

Of course, the application for aeroengine type certificate is not just for Zhang Yi and the Colorful Stone Group.

In fact, no matter which aerospace engine it is, from research and development to mass production to commercialization, generally speaking, three certificates must be obtained. The first is the type certificate, which is a certificate dedicated to aerospace engines. If

If it passes, it will prove that the design standards of this aero engine have reached the safety standards of aero engines.

Secondly, there is the production license, which is a certificate issued specifically to the manufacturer to prove that the manufacturer's quality system is sound and can guarantee the mass production of qualified aero engines under the manufacturer's production system.

However, due to the special nature of electric aviation engines, this certificate has been obtained by Zhang Yi and his Colorful Stone Group.

The third and most important certificate is the airworthiness certificate. This is a certificate specific to aircraft or aero engines. This certificate is equivalent to a car's driving license. If you don't have this certificate, install this engine.

Aircraft are not allowed on the road.

Generally speaking, no matter which aircraft manufacturer or aero-engine manufacturer it is, it is still difficult to obtain an airworthiness certificate for the first aircraft or aero-engine. The country will organize relevant expert teams and relevant departments.

Conduct joint reviews of their products.

Just like this time the country will review the electric aviation engine of Qicaishi Group, the airworthiness certificate of the first electric aviation engine must go through a joint review. Only after the joint review passes, the country will give this engine

Issue airworthiness certificate.

....

On the morning of the second day, Zhang Yi and the others hurriedly led everyone back to the Colorful Stone Group, and received a call from the relevant departments at noon that day. The expert team had already reviewed the information submitted by the Colorful Stone Group.

, the review was conducted and completed yesterday morning.

"Mr. Zhang, I am the leader of the Qicai No. 1 electric aviation engine review team. My name is Yun Haitao. Our expert team has completed the review of the written information of the Qicai No. 1 electric aero engine. We will arrive at your Qicai Stone this afternoon.

The group will conduct a comprehensive review of the actual electric aero engine of your group, as well as the engine production line, technical standards and other factors." Zhang Yi held the phone and paused Yun Haitao's notice.

Of course, he already knew about this. After all, the relevant departments had notified them just yesterday, and he also knew that there would be 10 experts coming to Qicai Stone Group this time, including a leader from the civil aviation department.

In addition, there are also necessary experts in aviation engines, electromagnetic motors, and other related experts.

He even saw among the members of the expert review team, Mr. Su, an expert who had previously conducted a review of super-heavy machine tools by the Colorful Stone Group.

So Zhang Yi feels that he is very lucky. After all, others may not know about the processing and manufacturing capabilities of Qicai Stone Group, but Lao Su is very clear about it. He even asked carefully about the electric machine when he came to Qicai Stone Machine last time.

The matter of aircraft engines.

Therefore, Zhang Yi can be sure that it is very easy for Qicaishi Group’s electric aviation engine to pass the review this time.

Sure enough, Qicai Stone Group passed the review of written materials easily, and now only the on-site physical review is left.

Despite this, Zhang Yi would never dare to be careless, and there were many things that were already settled, but ended up being messed up due to the negligence of the person in charge.

"Mr. Su! Mr. Shi! Welcome to Qicai Stone Group." When the review experts arrived at Qicai Stone Group, it was already past four o'clock in the afternoon.

Mr. Su was also very happy at this time. After all, he had a very good impression of Qicai Stone Group. When he came to review the qualifications for the development of heavy machine tools, Qicai Stone Group was already there when other companies were not prepared.

There are even more drawings, and now Qicaishi Group has developed an electric aviation engine that is actually unique.

As the leader of this review team, Dai Liangcai also had a good impression of Zhang Yi and his group, the Colorful Stone Group. After all, as the leader of the civil aviation department of the Dahua Empire, he was of course very happy that the Colorful Stone Group could develop an electric aviation engine.

What's more, according to the previous introduction of Qicaishi Group at the air show, Qicaishi Group has now developed three electric aviation engines. This is definitely the performance of a high-tech enterprise.

"Come! Mr. Zhang, let me introduce to you. This is Minister Dai Liangcai." Mr. Su said to Zhang Yi.

"Mr. Su, of course I know Minister Dai. Minister Dai once visited our Colorful Stone Group's booth at the air show before," Zhang Yi replied.

On the last day of the Shanghai Air Show, Dai Liangcai, as the leader of the civil aviation department of the Dahua Empire, took several leaders of the civil aviation department to visit the domestic aviation companies participating in the exhibition, including Colorful Stone.

group.

And because the engines produced by Qicaishi Group are different from those of other aviation companies, and there are more than one type, of course they were praised by Minister Dai.

Mr. Su then introduced other experts in the group to Zhang Yi. Zhang Yi also shook hands with these experts enthusiastically. After all, these are the experts who came to review. Zhang Yi must do some things well and leave them with

Make a good impression.

Zhang Yi then took these experts into the industrial park of Qicai Stone Group and came to a relatively large conference room in Zhang Yi's office building.

At this time, in the office, staff had already prepared tea and fruits, so everyone sat down and chatted. After all, it was already past four o'clock in the afternoon, and there was no time to conduct inspections on the Qicaishi Group's electric aviation engines.

Reviewed.

When the time reached five o'clock in the afternoon, Zhang Yi stood up and said to these experts: "Experts, it's already off work time, why not let's start the review tomorrow! Everyone is staying at the Colorful Stone Group.

"

Because the current Qicai Stone Group is no longer the Qicai Stone Group a few months ago, Qicai Stone Group has now built a complete dormitory area, and in the dormitory area, in addition to the dormitory buildings for Qicai Stone Group employees, Zhang Yi and the others

The Qicai Stone Group has also arranged several guest rooms specifically for non-Qicai Stone employees in the company's high-rise dormitory building, and these rooms are built according to high standards.

Since the time of this review is different from the last time, the last review of heavy machine tool development qualifications only lasted a few hours. In addition, the review was very strict, so naturally those experts would not eat or sleep here.

But this time is different. The review time this time is very relaxed, and it is not so strict compared with the last time. The expert group is naturally more casual.

After all, aero engines are no different than other engines. During testing, the trouble-free operation time is just that, as long as it takes, and there is no way to cheat at all.

Zhang Yi had naturally prepared a place for the expert group to eat. However, since the review had not yet begun, Zhang Yi did not arrange for the experts to eat elsewhere. Instead, he arranged for them to eat on the third floor of the factory cafeteria.

Although we only ate in the cafeteria of the Colorful Stone Group, the food was not bad at all and the ingredients were very rich. However, since it was the group's cafeteria, there was no alcohol.

After a speechless night, the next morning, Zhang Yi mainly led these review experts to visit various factories and workshops of Qicai Stone Group, but Zhang Yi did not take them to see some sensitive places.

However, when Zhang Yi led these experts into a workshop, what caught the eyes of these experts was a huge machine. Although the machine was being installed at this time, it can be seen from the prototype of the machine

, this is definitely a super heavy machine tool, and not an ordinary super heavy machine tool.

"Mr. Zhang! This! Is this the super-heavy and ultra-high-precision CNC machine tool designed by your Colorful Stone Group? The final assembly has started so soon. It seems that it has not been a month since our last mission review!" When I saw this

When he saw a huge machine, Mr. Su, as the leader of the last super-heavy machine tool audit expert team, said in great surprise.

"What! This is a super-heavy and ultra-high-precision CNC machine tool, which is also the legendary industrial machine?" After hearing Mr. Su's words, all the experts present were very surprised.
Chapter completed!
