The design weight of the central wing box manufactured by Sinoking Aviation Technology is several tons, containing thousands of components, and the assembly accuracy is controlled at 0.8 mm, which is very demanding for processing, but it is not particularly difficult for Huake Aviation Technology Company, which has a large number of middle and senior technicians. ▲≥ Eight ▲ ≥ Eight ▲ ≥ Read ▲ ≥ Book, .√.≧o

In addition, the nose and tail and fuselage components of Huake Aviation Technology Co., Ltd. and Xifei Group, Shenfei Group, Chengfei Group, Hongdu Group and other companies have signed contracts, and the materials company under Huaxing Group will provide these companies with titanium matrix composite materials and equipment technology for processing.

Because the H-10 strategic bomber flies at supersonic speed, Huake Aviation Technology Company uses very little epoxy resin glued composite materials, and these domestic companies have no experience in the processing of this titanium-based composite material, so Huaxing Group takes the initiative to help these group companies master the processing technology of these materials, in order to speed up the production progress of the H-10 strategic bomber.

Of course, the formulation and preparation process of these titanium matrix composites are the secrets of Huaxing Group and will not be transferred.

The material factory of Huaxing Group is now producing in large quantities, in order to meet the needs of Huaxing Group's large number of aircraft and rockets.

Yang Jie then came to the forging plant with a 60,000-ton press, where a skilled worker drove a giant robotic arm to remove a red-colored part from the vacuum furnace next to it, and then drove a forklift to put the part into a mold under the press.

As the huge hydraulic cylinder pushes the upper mold downward, sparks erupt from the parts inside as the two molds begin to close. ∈ 8∈8∈ read ∈ books, .≦.o≧

After a few minutes, the upper and lower molds were then separated, and the parts inside had been pressed into a complexly shaped fuselage girder, almost two meters long.

Titanium alloys such as fuselage girders must be forged to meet the design requirements, and after forging, they need to be sent to a vacuum furnace for annealing again, and after cooling, they must be sent to a CNC machining center for processing.

High-temperature materials such as titanium alloy are very difficult to deform, and must be heated to a certain amount of pressure to forge, and only after forging can the internal crystals be refined to meet the design requirements.

These girders and fuselage reinforcements are firmly riveted together by fasteners to form a sturdy fuselage that can withstand the weight of dozens of tons of dàn yào under the belly and the impact when landing.

Seeing that the progress of the H-10 strategic bomber was being carried out in an orderly manner, Yang Jie was very satisfied with this.

In the evening, he also held a meeting at Huake Aviation Technology Company to listen to the development progress of the company's internal model YsZ02 stealth fighter.

Now the research and development of Huake Aviation Technology Company on the H-10 project has been accepted, and the team led by Song Daozheng has also transferred to the research and development of stealth fighters.

This time, the design team of Shenfei Aircraft Design Institute and Huake Aviation Technology Company also came up with a lot of design sketches, which were placed in front of Yang Jie at this time.

Yang Jie saw that a group of experts were looking at him, and he smiled after reading these sketches: "I also took a closer look at these design sketches, and my opinion is to select two from them." ”

"Two?"

Everyone in attendance was taken aback.

"Yes, one for the customer, one for the big food country, the best one for ourselves, and the other for the customer. ”

Yang Jie said: "However, in order to avoid wasting resources, most of the components of these two types of aircraft must be common. ”

The requirements of the big food country for Huake Aviation Technology Co., Ltd.'s stealth fighter are to be able to compete with the F35, and there are no requirements for specific details, and it is also very happy to call over billions of dollars in research and development funds.

Yang Jie naturally wants to make good use of this money.

"It is best to develop our own stealth fighter on the basis of the J-15, which is what we are best at, and I won't say much about the rest. ”

Yang Jie opened his mouth and said.

Huake Aviation Technology Co., Ltd. has established a very strict R&D and design process in aircraft development, and the performance and quality of the fighter jets developed by the company in accordance with this process over the years are very guaranteed, and Yang Jie will not interfere too much.

Although he has also consulted many experts on aviation knowledge over the years, and he has become half an expert in this field, the specific things still depend on these experienced expert groups to complete.

In fact, the military also greeted Yang Jie about Da Shiguo's order to design a stealth version of the fighter from Huake Aviation Technology Company, and Yang Jie also assured that the company's most advanced product technology would not be used in exported military aircraft.

A few days later, Yang Jie also participated in the opening ceremony of the first "Huaxing Cup" artificial intelligence algorithm competition held at Meixihu University.

At present, Meixihu University has provided an open-source development toolkit to some companies at home and abroad, and good results can be achieved after using this toolkit through training data.

Open source code can be used, but it is not professional and pertinent enough, and the effect often cannot meet the actual requirements of specific tasks.

Taking image recognition as an example, even though AI developed with open-source code can accurately recognize faces, it is difficult to meet clinical requirements in the recognition of medical images.

Taking the identification of liver lesions as an example, it is difficult to accurately identify liver lesions with open source code due to the difficulties of blurred boundaries, low contrast, organ adhesions and even overlapping. It is difficult to accurately reflect the real anatomical information in 3D reconstruction and visualization, and even misleading, which is disastrous in medical application.

In other words, the AI "tuned" by open source code is at most an "ordinary person", and to help AI grow into an expert in subdivided fields, it needs to innovate the original core model, code, and framework based on mathematics.

The reason why Huaxing Group has been able to make breakthroughs in some subdivisions is mainly due to the fact that the group company has gathered a large number of mathematicians to help the group company make great breakthroughs in the original algorithm model in some fields.

At present, Huaxing Group is very bright in AI, mainly relying on the huge computing power and huge storage capacity of computers, and the problems of the underlying algorithm may not be prominent.

Yang Jie is also aware of this problem, and AI will encounter a very big hurdle in the future, that is, AI will probably be integrated into logic, thinking and other wisdom content, which requires original innovation in mathematical science, and there are a large number of basic problems to be overcome by mathematicians.

The reason why he held such an international competition and spent a lot of money was mainly to attract more mathematicians to actively invest in the original algorithm model of artificial intelligence. 11
