A few days later, Yang Jie accompanied Song Xinyang, Zhang Haiping and others to visit and inspect Shaanxi Fei Group Company, and then came to Xifei Group Company.

Founded in 1958, Xifei Group has developed and produced dozens of different types of military and civil aircraft, such as Y-7, Y-8, H-6, Xinzhou-60 and J-7, for more than 40 years.

Xifei Group covers an area of more than 3 million square meters, including more than 1.3 million square meters of construction area, has more than 20,000 employees, has more than 6,000 sets of equipment, including more than 1,600 sets of metal cutting equipment, more than 70 sets of large-scale precision processing equipment and more than 30 new technology production lines, basically reached the international level at the end of the eighties of the last century——

In recent years, the state has given great support to Xifei Group Company.

In comparison, Huaxia Fokker Company now covers an area larger than that of Xifei Group, with a construction area of more than 1.5 million square kilometers, but it has only more than 14,000 employees.

However, the revenue of such a large company of Xifei Group last year only exceeded 10 billion, and the company included three main business incomes of military products, civilian products, general aviation, and international cooperation, which was also responsible for the central wing, flap, vertical tail, door, wing box antistatic floor and other components of several models of passenger aircraft of Huaxia Fokker Company, with a business amount of more than one billion.

Strictly speaking, Huaxia Fokker is a major customer of Xifei Group Company.

The senior management of Xifei Group Company also muttered to Yang Jie standing beside several central bosses: What is the purpose of this master following the big chief?

Xifei Group Company is very close to Huaxing Group Company and Second Harbor Group Company, especially with Hongdu Group Company, which is a subsidiary of Second Harbor Group Company, and its mentality is relatively complicated.

Hongdu Group Company's Qiang-5G is now being purchased in large quantities by the Air Force and Navy, and this model has been officially changed to J-9, because Hongdu Group Company previously had the J-8 model, in order to avoid repetition, so the model was changed to J-9.

Xifei Group Company is convinced by the high performance of this J-9, because this J-9 is not only fighting in the Lion Country, but also fighting on the side of the Sabbatical State, and it is said that the performance is more fierce than the F-15 fighter.

To tell the truth, Xifei Group is very envious here, Hongdu Group Company has been blessed by the technology of Huaxing Group Company, in recent years, it has been really a big deal, not only launched a senior training aircraft, and then also launched the J-9 model, domestic and foreign customers are rushing to want.

Even in civilian products, the fuel cell two-wheeled vehicles launched because of the relationship with Huaxing Group are simply selling crazy, and it seems that 4 million units have been sold this year, and they have begun to be exported, and this business alone has exceeded 14 billion in revenue.

Now Hongdu Group has become the most profitable company among the domestic state-owned aircraft enterprises.

The senior management of Xifei Group Company said that it was a lie not to envy it.

In the afternoon, in a very old assembly workshop of Xifei Group Company, Yang Jie also saw two prototypes of White Swan that Xifei Group took several years to make.

Of course, this prototype is all made of wood.

"These prototypes can't fly, why do you produce so much? Prototype airplanes made of wood are only used to verify the design and structural problems, and it is impossible to get more technical ......."

Yang Jie saw the two white swan prototype models made exactly according to one to one, and couldn't help but feel a little heartache carpenters.

Many parts on the aircraft, machining requires very rich experience and technical foundation, carpenter production, in the CNC machine tool has not been introduced into this field, it is even more difficult.

"Another purpose of our production is to train our team of assemblers. These models are manufactured in exactly the same way as a normal airplane, with the added benefit of significant cost savings......"

He Hongfeng, the deputy chief engineer on the side, hurriedly explained.

"After all, we have very few members of the project team, and the project team has only received a total of 30 million funds over the years. ”

Wood is easy to process, low cost, and doesn't even need to consider the processing properties of the material, so even if something goes wrong and it is scrapped, it can be replaced quickly.

"In this way, your carpentry team is very good!"

Zhang Haiping smiled.

Yang Jie also knew that when the first nuclear submarine in China was designed, there were only two blurry photos taken from foreign media newspapers and a nuclear submarine model purchased from abroad as the basis.

In this case, you can only figure out the proportions of the shape, and everything else is starting from scratch.

At the time of the initial design, the designer first designed the outer shell, and then gradually installed various parts and components inside, and if it was not suitable, it was adjusted, redesigned, and reprocessed.

This method still retains such a traditional method in the domestic Xifei Group Company.

In fact, in the previous life, when the Soviet Union built the Buran Space Shuttle, it also adopted the method of carpentry to make prototypes, and most of the parts were made of wood.

The Soviets were always better at finding more cost-effective ways than the Americans, and who would have thought that the first prototype would be made of wood, such as the Buran Space Shuttle, which is currently considered the world's top high-tech integrated product?

He Hongfeng said: "Chief, we have no way to do it, we are not as rich as Huaxia Fokker Company, so we can only use wood to make models if we have any modifications or anything." This is also relatively fast, and at the same time, we can achieve our goals at the lowest cost. ”

Yang Jie smiled: "Although it is easier and cheaper to build a model from wood, the disadvantages are also very obvious. These wood models are not tested in the same way as full-scale prototypes. Even, because it is too heavy, the main structure will be affected. ”

"That's true. However, it is very useful when prototyping, and it can reduce the cost a lot. ”

Song Daozheng, the chief designer in charge of the project, said at this time.
