Fan Wei has achieved brilliant political achievements with Du Kang Liquor's restructuring and his career was full of success. He is a person who knows how to advance and retreat. Of course, he should curry favor with Ke Youli, the immediate boss. Now that he heard Yang Xing leaked the news that the central government wanted to establish an aviation industrial park and open low-altitude aviation management rights in Jiudu in advance, he understood that this would not be Yang Xing's targetlessness, and there must be some information. This is a great thing to add luster to Ke Youli, so after expressing his achievements, he immediately asked Yang Xing for details on his behalf.

Although he had Hainan's plan to develop the aviation industrial park and open low-altitude routes, Ke Youli also knew that it would not work according to the map. Many places and places are incomparable. Hainan has long since released its air rights, and the pilot program of low-altitude routes has been secretly carried out for a while, attracting a large number of domestic wealthy people to test their own private planes here. He is very experienced, and now it has just been officially recognized by the central government.

Hainan's airport construction has always been at the forefront of the country and is considered to be the most promising area in China to become an international route transit hub. The soon-to-be-completed Wenchang Aerospace Base represents the special significance of Hainan in the domestic aerospace and aviation field. Ke Youli already knows that Yang Xing's other friend Zhang Shengli and a group of domestic wealthy people plan to invest in the construction of the first general aviation company in China and build a flight base in Hainan. In contrast, he only has plans that others have used, and needs to be digested and absorbed. To come up with plans that meet the situation of Jiudu, he may be far behind other cities.

To change all this, we can only ask for help from the young man who is less than 30 years old in front of us. Ke Youli also sighed in his heart. He asked himself that he was also an extremely outstanding genius from the political family. He could reach such a high position at this age, and even Fan Wei, who had a lot of resources, could not compare with him. He could be said to be the best among his peers with rare opponents, but when facing Yang Xing, he was still suppressed by him. It seems that he can only cooperate well with him in the future and don’t be competing for strength again.

Yang Xing also realized that Ke Youli's current attitude is different from the false enthusiasm of the first one, but he couldn't care about this. The other party could put down his posture and discuss the matter of the Aviation Industrial Park, and he knew that cooperation would not encounter too much trouble in the future. After all, Jiudu was the place where he made his fortune and had some feelings. To be honest, it was beyond his expectations that the central government could agree to build the Aviation Industrial Park here, but it was a good thing after all. Before he came, he asked the group experts to collect various relevant information, and had a long history of how Jiudu developed his own unique aviation industry.

"You all know the plan for the big plane?" Yang Xing asked them first. Both of them nodded to express their understanding. There is no airtight wall in the world. China's economy is now growing rich. As a big country, launching its own plan for the big plane again has not caused much turmoil at home, but has only caused a hustle and bustle abroad. Because China is just developing large military transport aircraft. As the five permanent members of the United Nations, China's strategic transportation capacity is the worst, which has always been a shortcoming. There are only a few large strategic military transport aircraft purchased from Russia. It is not easy to criticize others for the development of 200-ton strategic transport aircraft.

However, the market for civilian 100-seat trunk aircraft was dominated by Western aircraft such as Boeing 737 and Airbus A320. Now China wants to move this cake. Opposition and ridicule are everywhere. It is believed that China will only repeat the mistakes of developing the "Yun Ten" aircraft back then, and waste money and waste money.

But Yang Xing knew how determined the central government was to this, with Soviet secret files as the foundation, and the current progress of the domestic aviation industry can be said to be rapid. When he visited the domestic "Nuclear High-Basic" Achievement Exhibition, the heart of the large aircraft led by "Taihang" - the large thrust turbofan engine, had been successfully tested. Now the "large aircraft" must have made greater progress. Yang Xing believes that as long as the difficulties can be overcome, the military and civilian aircraft in the large aircraft plan will sooner or later fly into the blue sky, which will definitely be earlier than in the previous life.

Although Ke Youli was born into a political family, his family had little relationship with the military. He did not understand this enough, so Yang Xing explained to him in detail that in fact, the support for the aviation industry has been increasing in recent years. The momentum of the aviation industry becoming the pillar of the national economy is rapid, and the relaxation of low-altitude aviation rights management and opening up aviation access to private capital are both earlier than in the previous life. This shows that the central government's policy preference for the aerospace industry is very attractive to both local and private parties. This time, the approval of the experiment of relaxing aviation control and establishing aviation industrial parks in so many cities is obviously intended to promote competition and improve the level of aviation manufacturing.

Compared with other cities with a certain aviation technology foundation, Jiudu has a relatively weak foundation, but it also has its own unique advantages. The first point is that Jiudu has strong equipment manufacturing capabilities, especially leading the domestic level in processing large equipment and CNC machine tools. Large aircraft are the crystallization of high technology in the industrial era, requiring tens of thousands of parts and thousands of processes. Many of them have less processing accuracy than one hair. The titanium alloy material used in the aircraft beam needs to be forged and pressed in one go, and Jiu will not lose to other cities whether it is equipment or processing.

Secondly, Jiudu’s newly emerging microelectronics development capabilities have also helped the aviation industry greatly. Electronic equipment in modern aircraft accounts for more than half of the total cost, and the cockpit is basically "glass-transformed", that is, electronic equipment such as LCD displays replaces traditional mechanical instruments, and telematics control replaces mechanical operations. The core equipment of the Air Force, which was a successful test flight not long ago, has many electronic products from Jiudu. In particular, the military microprocessors used in the on-board phased array radar control center are all provided by the chip factory secretly established by Zhongxing and the military. Its predecessor was the monocrystalline silicon factory where Zhang Shengli’s parents are located. Zhang Shengli is very proud of this. Fan Wei and Ke Youli also participated in the Air Force’s conference to commend relevant units supported by Jiudu not long ago, and have heard of this.

The third point that Yang Xing talked about is undoubtedly the most attractive to Ke Youli and others. He put forward a refreshing insight, that is, Jiudu can adopt differentiated competition methods to make a fuselage on aviation materials. Yang Xing said that in fact, the earliest aircraft structure was not complicated. It was nothing more than that the engine drove the propeller to rotate, allowing the fuselage made of wooden frames to obtain sufficient speed with the help of special-shaped wings and then flew into the sky. There are two core points here, one is an engine that can provide sufficient power, and the other is a light and sturdy fuselage. This involves the key technology second only to the engine in the aviation industry - materials.

Before World War II, aircraft were still made with wood, but after the war, it entered the jet era. Wood obviously could not meet aviation needs. Aircraft have widely used metal aluminum alloy shells. Now, the proportion of metal alloys in the fuselage materials has been greatly reduced, and the proportion of composite materials has increased significantly. However, the development time of domestic composite materials is short, and it is difficult to find composite materials on most domestic aircraft. In this regard, foreigners belittle us for decades of technical courses to make up. Fortunately, China has noticed this. In recent years, it has strongly supported the introduction of new composite materials technologies and provided policies and funds to support such enterprises to expand production scale. Yang Xing developed from Formosa Plastic Energy to carbon fiber technology last year and quickly put into production of composite materials production lines. The support of the government is inseparable from government support.

In the engines at the heart of the aviation industry, high-temperature materials are a concentrated reflection of a country's manufacturing level. As the engine thrust continues to increase and efficiency continues to rise, the outlet temperature must be increased. The thermal efficiency of modern aviation turbofan engines has reached more than 42%, which is the most efficient and cleanest power equipment. However, to achieve such thermal efficiency, the maximum engine temperature needs to reach more than 1500c. When ordinary materials reach this temperature, they will inevitably turn into a ball of gas. Even steel becomes softer than noodles. Scientists have always hoped to find a material that is particularly resistant to high temperatures, and the most mature one is high-temperature alloy.

High-temperature alloy is a metal material that can work for a long time under conditions of above 600c and certain stresses. It has excellent high-temperature strength, excellent oxidation and thermal corrosion resistance, good fatigue resistance, fracture toughness and other comprehensive properties. It has become an irreplaceable key material for hot end components of military and civil aviation engines and gas turbine engines.

The "heart disease" problem that domestic aero engines have always been widely criticized. In fact, to put it bluntly, the difference lies in materials. After World War II, the United States and Britain gradually eliminated iron, aluminum and other metals on traditional engines with their deep technical strength, and developed high-temperature alloys based on iron, nickel and cobalt. Because the high-temperature alloy has a high degree of alloying, it is also called "super alloys". It has been widely used in aviation, aerospace, petroleum, chemical, ships and other fields. Among them, nickel-based high-temperature alloys occupy a special important position in the entire high-temperature alloy field and are widely used to manufacture aviation jet engines and the hottest end components of various industrial gas turbines.

The technological progress of aircraft engines is closely related to the development of high-temperature alloys. High turbine operating temperature is the most significant sign of contemporary advanced aircraft engines. Increasing the turbine operating temperature is an important means to increase thrust and increase the thrust-to-weight ratio of the engine. The primary factor affecting the temperature before the engine turbine is the temperature resistance level of the turbine blades and turbine discs.

At present, nickel alloys account for half of the total weight in advanced engines. Not only turbine blades and combustion chambers, but also turbine discs and even the subsequent compressor blades have begun to use nickel alloys. Developed countries have also begun to use nickel-based single crystal high-temperature alloys. It can be said that the birth of each generation of high-temperature alloys marks the emergence of a new generation of aviation engines. There is a famous saying in the aviation industry, "One generation of high-temperature alloys, one generation of new engines."

Now the fourth-generation high-temperature alloy in the United States has been launched, and the second-generation high-temperature alloy is widely used in the f119 engine used in the f22 fighter jet. The second-generation high-temperature alloy in China has just passed the acceptance, and some of it is used on the Taihang engine, but the reliability and service life are still quite different from similar products abroad.
