Pakistan's $1 billion arms order business was handed over to Tan Lin to take care of, and Ross had a good night's rest, and after getting up the next day, he began to devote himself to the development of engines.

The engine is the heart of the industry, and the engine in China is backward in technology compared with developed countries.

The American engine can be used for 10,000 hours, the Russian engine can be used for 4,000 to 6,000 hours, and the Chinese engine can only be used for 2,000 hours.

The backward performance and short life of Huaxia's domestic engines have caused an embarrassing situation. Even the military of Huaxia does not look down on domestic engines, and Huaxia's advanced fighter jets have always used engines imported from Russia.

Without advanced engine technology, Huaxia has been lacking in confidence in the face of the West.

Once Russia stops exporting those engines to China, it will be difficult for domestic engines to meet the demand for fighters.

Huaxia's engine technology was developed decades later than in the West. Therefore, there is a huge gap with foreign countries on the basis.

In fact, some of the design concepts of Huaxia engine are very advanced, but they can't be built.

In desperation, in order to meet the temporary demand, in addition to imports, Huaxia can only clone mature foreign engines to solve the needs of industry and national defense.

This kind of copycat behavior to solve the urgent need has caused Huaxia's engine to be using the backward version of foreign countries ten years ago.

The gap between Huaxia engine and foreign countries, in addition to the problems in design, is also the gap in precision machining technology.

The engine has a very high technical content, and the demand for precision is very strict, and a small difference in accuracy will cause a great reduction in the engine function.

Huaxia is not as advanced as Europe and the United States high-end precision machining machine tools, foreign countries have not been exported to Huaxia, and Huaxia can not be manufactured. So on top of the engine manufacturing process. There are gaps.

But now the problem of this high-end precision machine tool is not a problem for Ross.

Before the Chinese New Year, Ross cooperated with 30 of the most cutting-edge precision machining machine tool manufacturers in China, and the advanced machine tool drawings and CNC software provided by Ross to them are the technology of the future. It only needs to be manufactured according to the drawings.

Coupled with the assistance of the national nuclear laboratory and the laser laboratory, as well as the super performance of special steel, those companies should be able to produce the most advanced domestic high-precision machine tools.

Ross immediately dialed the phone and asked the 30 machine tool manufacturers about high-precision machine tools.

Ross was overjoyed by this inquiry, and five of the companies had already mastered a small part of the technology that Ross had provided. With the help of the state, several state-of-the-art high-precision CNC machine tools have been produced.

Ross was overjoyed and immediately ordered these 5 companies. The experimental machines they produced were sent to Uta, and it was up to Ross to determine whether they could perform high-precision machining. If these machines are qualified, Ross will already be able to manufacture engine blades.

In addition to precision machining technology, the material metal technology of the engine is also the key to restricting the engine. A small material difference, the result is very obvious. Take the most common saw blade, a saw blade in the United States. The life span is equivalent to the life of 5 saw blades in Huaxia.

Material problems have restricted the development of engine technology, the most typical of which is the turbine single crystal blade material of the engine, and the country has not been able to make the kind of single crystal blade comparable to the most advanced technology outside the United States.

The high temperature generated by the engine when working reaches 2000 degrees at every turn, while the melting point of ordinary metal is about 1500 degrees.

If the materials used to make the blades cannot withstand high temperatures, it is easy to have problems such as leaf ablation, fracture, and chip dropping, once they go wrong. There will be big problems with the engine.

In addition to high temperature resistance, the strength of the blade is also important, if the material is not strong, the rotation speed will be unstable over time. Excessive wear will cause the life of the engine blades to decrease, which will reduce the life of the engine.

In addition to strength, wear resistance, and vibration resistance, precision perforations on the engine blades are also important, and these small solid blades must be drilled with hundreds or thousands of holes to form a cold air channel.

The material problem of the engine is no longer a problem for Ross, who has already made a super ceramic metal.

Ross doesn't even need to make any single crystal blades, just make the engine blades out of ceramic metal. These ceramic metal blades, which will be resistant to high temperatures of up to 3,500 degrees, are a piece of cake to meet the various needs of the engine.

As for the three cores of the engine: a high-pressure compressor, a combustion chamber, and a high-pressure turbine. These are the most critical core components of the engine, and Ross cannot make them by himself. Before the Lantern Festival, he had already designed these core components and provided a large number of drawings and technical parameters to General Xu.

Relying on AVIC, Chuanfei, Shenfei and Xifei...... The strength of other airlines, coupled with the efforts of tens of thousands of scientists in the space center, and the concentration of the best experts in the country, it is not a problem to produce and manufacture these components.

Ross immediately dialed Admiral Xu's phone again and asked Admiral Xu about the development of the core components of the engine.

After receiving a call from Ross, Admiral Xu was extremely excited: "Major General Luo! These days, I'm fainting. The drawings and technical information you provide are too precious. On the day they got the drawings, the entire Ministry of Industry and Aerospace and the Ministry of Defense, everyone couldn't sleep. Everyone gathered the leaders of the four major airlines overnight. people, formed a team of experts, and conducted research on the technology overnight.

In order to get the engine, our country has begun to concentrate the strength of the whole country, concentrate all the advantages, is overcoming these difficulties, we have tens of thousands of people rushing to the front line of major production. I believe that it won't be long before we can figure out the key technologies of the core components you mentioned. Rose, how about the blades? The most important turbine fan blades, you made out no. ”

Ross smiled: "The blades of the engine are not a problem for me. As long as you can get those core components, give me the monocrystalline blades, and soon I will send the finished blades to the Ministry of Defense. ”

"Rose! I heard that you made ceramic metal, which is advanced and can be used as a material for engine blades. But how to solve the problem of blade size, precision perforation, and precision machining machine tools? ”

"Grandpa Xu, these questions, for me, are not a problem. You guys keep busy, I'll go work on the blades, get it done, and call you again. Everyone works together and hopes that the domestic super engine can come out soon. ”

"Well, I'll call you as soon as the parts you mentioned are made. Major General Luo! I had to get busy, and in order to get the engine out early, I had to supervise the work on the job site. Bye! ”

"Goodbye, Admiral."

After hanging up the phone, Rose breathed a sigh of relief.

China's four major airlines, plus tens of thousands of experts from the aerospace department and major scientific research institutions, rushed to the four major aircraft factories.

They only need to make it according to the drawings, and the materials are their own special steel alloys, and if they can't make the engine parts of those planes, then they can only say that they are not saved.

Sitting in his office, Ross began to concentrate on designing the blades of the engine, and once they were designed, they would be ready to be made when the high-precision machine tool arrived.

Huaxia is using the power of the whole country to cooperate with Ross to cure the heart disease of Huaxia Industry, once the super engine comes out, it will become a symbol of Huaxia's rise. (To be continued......)
