The H-10 strategic bomber is expected to be able to complete the final assembly of the first one in July, and the other will be able to complete the final assembly and roll off the assembly line in September.

One of the two prototypes will do ground static testing, and four prototypes will be produced next year, in addition to two prototypes for ground testing, the other prototypes will carry out intensive test flight missions for more than a year, and it is expected to be able to complete the test flight mission by the end of 10 years, and then enter the stage of mass production.

The main reason for the production of so many prototypes in a short period of time is to gain time, compress the test flight time as much as possible, and let this strategic bomber be equipped with troops as soon as possible.

Of course, this will naturally require greater capital investment and technical risk, after all, the trial production batch is put into production before the prototype test flight is completed, and once there is a large-scale change in the design, it needs to be modified on multiple aircraft on the production line, and if this change is large, it is even necessary to scrap the production machine that cannot be improved.

Of course, Sinoking Aviation Technology Co., Ltd. has long introduced the whole process platform technology of digital prototype, and the whole process of digital prototype has been completed before the prototype is officially manufactured, and the whole process only took more than a year, and the problem of requiring a large number of design changes has been solved before the production of the physical prototype begins.

At present, it takes about three years for a fighter at home and abroad to complete the engineering verification of the aircraft, and only after the completion of this stage will it enter the stage of prototype production and flight testing.

However, Huake Aviation Technology Co., Ltd. has greatly reduced the time with digital prototype platform technology, and even realized digital simulation on the computer to simulate trial production and flight test, and carried out various simulations of the problems encountered in these stages of the physical prototype in advance, which greatly reduced the amount of design modification in the future.

Because Huaxing Group has been in the research and development of digital simulation technology for almost ten years, the stability, accuracy and speed of the simulation test have been greatly improved, and the results of the simulation test have been very close to the actual experimental test results.

With the help of such a digital prototype platform system and high-tech weapons, it is natural that the research and development efficiency of the H-10 strategic bomber will be greatly improved.

At present, many companies under the domestic aerospace group company have introduced the whole process of Huaxing Group's digital prototype platform system.

Zhang Haiping also greatly appreciated the development progress of Huake Aviation Technology Company.

Subsequently, Zhang Haiping and others also visited the silicon carbide whisker material factory under Yonghan Aviation Technology Company.

Silicon carbide whiskers are a single crystal fiber with few defects and a certain aspect ratio, which has quite good high temperature resistance and high strength, and is mainly used for toughening occasions that require high temperature and high strength application materials.

This material was developed by the technical team led by Liu Fuping on the basis of Ximenkang's silicon carbide technology, and several of the engineers are technicians from Ximenkang.

In this regard, in fact, the synthesis of silicon carbide by Eagle Sauce and Neon Country was the first to start, and a lot of research work was carried out in reducing costs and improving quality.

Several domestic companies in Eagle Sauce use amorphous silicon oxide from rice husks as silicon sources, and mix crushed carbonized rice husks with powdered petroleum coke to produce silicon carbide products.

Several domestic companies of Neon have prepared high-purity silicon carbide products through pickling rice husks, impurity removal, carbonization, sintering and other steps.

Yonghan Aviation Technology Co., Ltd. has developed a unique silicon carbide whisker material production process on the basis of Ximenkang's technology, and has also obtained high-purity silicon carbide whisker material, and the silicon carbide whisker produced is a high-strength whisker-like single crystal, with high strength, high modulus and many other excellent mechanical properties.

This silicon carbide whisker material is known as the king of whiskers, and its addition has significantly improved the fracture toughness, flexural strength and other properties of the composite material. As an excellent reinforcing and toughening agent, the metal-based, ceramic-based and polymer-based composites with this whisker material have been widely used in Huaxing Group in machinery, chemical, aviation, aerospace, shipbuilding, automobiles and other products.

At present, Yonghan Aviation Technology has achieved mass production and is divided into β types of whisker materials, which have higher hardness, better toughness and conductivity, wear resistance, high temperature resistance, especially earthquake resistance, corrosion resistance, radiation resistance and other characteristics than α type.

Zhang Haiping also carefully visited the production line, the 60-acre factory covers an area of 5,000 tons, the design output is 5,000 tons, and the second phase is still under construction, and the production capacity will reach 10,000 tons in the following year.

Of course, the only company that can produce high-purity silicon carbide whisker materials in China is Yonghan Aviation Technology Co., Ltd., and there are several experimental production lines in China, and the output is very small, including the Jinshan Silicate Research Institute under the Chinese Academy of Sciences, but it is not as good as Huaxing Group in terms of mass production technology, and the purity cannot reach such a high purity.

The production of other whisker materials also has a Jinshan whisker composite material, which is earlier than this whisker material factory, but the production of potassium titanate whisker series products, this whisker material is still inferior to silicon carbide whisker material in terms of high temperature and hardness.

Zhang Haiping looked at the silicon carbide whisker material powder in the glass container in surprise at this time, turned his head and said to Yang Jie: "You have to increase the supply of such a good material!"

Yang Jie smiled and nodded: "After the second phase of the factory is completed, we will give priority to other domestic enterprises to provide this whisker material." ”

Compared with carbon fiber composites, the process of incorporating whisker materials into other materials is relatively simple, and the process cost is cheaper than carbon fiber composites.

Carbon fiber composite materials are prepared by tape laying and autoclave curing process, in fact, the use range of this material is still very small, because this composite material is bonded with epoxy resin material, and the working temperature is only a few hundred degrees, and it is naturally no problem to use it on civil airliners, but the cost of this process is still too high.

The silicon carbide whisker material can be easily incorporated into metal-based materials through powder metallurgy technology, and it is also easy to incorporate in ceramic, glass, and plastic matrix materials, which is lower than the process cost of carbon fiber composite materials.

Therefore, the R&D focus of Huaxing Group has begun to shift to silicon carbide whisker materials.

The research and development of whisker materials began relatively early abroad, and in the eighties of the last century, such materials began to be sold in Eagle Sauce and Neon Country.

However, the technical team obtained by Huaxing Group from overseas also has rich experience in this area, and will not lag behind in technology, and the advantages of Huaxing Group's vertical industrial chain, this material will be transformed into various products immediately after production, so it is the first to use this material in large quantities like the H-10 strategic bomber.
