Chapter 152:

Pakistan ’s $ 1 billion arms order business was left to Tan Lin to take care of. Ross took a good night's rest, and after getting up the next day, he began to work on the engine development (Chapter 152 of Natural Science and Technology Mania).
The engine is the heart of industry. Compared with developed countries, Huaxia's engine is backward in technology.
The American engine can use 10,000 hours, the Russian engine can use 4,000 to 6,000 hours, and the Huaxia engine can only use 2,000 hours.
The performance of Huaxia's domestic engines is lagging behind and its short life has caused an embarrassing situation. Even Huaxia's military doesn't look down on domestic engines, and Huaxia's advanced fighters have always used engines imported from Russia.
Without advanced engine technology, Huaxia has always been short of confidence in the West.
Once Russia stopped exporting those engines to Huaxia, domestic engines would be difficult to meet the demand for fighters.
Huaxia's engine technology was developed decades later than the West. Therefore, there is a huge gap with foreign countries on the basis.
In fact, some design concepts of Huaxia engines are very advanced, but they cannot be made.
In desperation, in order to meet temporary needs, in addition to imports, Huaxia can only clone foreign mature engines to meet the needs of industry and national defense.
This imminent copycat behavior has caused Huaxia's engine to use the backward version of a decade ago abroad.
In addition to the design problems, the gap between Huaxia engines and foreign countries is also a gap in precision machining technology.
The engine technology content is very high, and the demand for precision is very strict. A small difference in precision will cause the engine function to be greatly reduced.
Hua Xia does not have the advanced high-end precision machining machine tools as advanced in Europe and America. It has not been exported to Hua Xia abroad, and Hua Xia cannot make it. So there is a gap in the engine manufacturing process.
But for this high-end precision machine tool, there is no problem for Ross.
过 Before the Chinese New Year, Ross cooperated with 30 domestic cutting-edge precision machining machine tool manufacturers. The advanced machine tool drawings and NC software provided to them by Rose are future technologies, and only need to be manufactured according to the drawings.
Plutonium plus the assistance of the National Nuclear Laboratory and Laser Laboratory, as well as the superior performance of special steel. Those companies should be able to produce the most advanced domestic high-precision machine tools.
Mr. Ross called the phone and asked the 30 machine tool manufacturers about high-precision machine tools.
In response to this inquiry, Rose is very pleased. Five of them have already mastered a small part of those technologies provided by Rose. Cooperate with the help of the state. Several state-of-the-art high-precision CNC machine tools have been produced.
Rose was overjoyed, and immediately ordered the five companies to send their experimental machines to Yuta Company, and Rose determined whether these machine tools could perform high-precision machining. If these machines are qualified, Rose can already make engine blades.
除了 In addition to precision machining technology, material and metal technology, this is the key to restricting the engine. A small material difference brings very obvious results. Take the most common saw blade, the life of one saw blade in the United States is equivalent to the life of five Chinese saw blades.
Material problems restrict the development of engine technology. The most typical one is the turbine single crystal blade material of the engine. The country has not been able to produce a single crystal blade comparable to the most advanced technology outside the United States.
The high temperature generated when the engine is working can reach 2000 degrees, while the melting point of ordinary metal is about 1500 degrees.
If the materials used to make the blades cannot withstand high temperatures, problems such as blade ablation, fracture, and chipping are likely to occur. Once they fail, the engine will have major problems.
In addition to high temperature resistance, the strength of the blade is also important. If the material is not strong, over a long period of time, the speed will be unstable and excessive wear. Will cause the life of the engine blade to decrease, which will reduce the life of the engine.
In addition to strength, wear resistance, and vibration resistance, precise perforations on the engine blades are also important. These small solid blades must be perforated with hundreds or thousands of holes. To form a cold air channel.
The problem of the material of the engine is no longer a problem for Rose, who has already produced super ceramic metal.
Jeros doesn't even need to make any single crystal blades, just use ceramic metal to make the starting blades. These ceramic metal blades can reach a high temperature of 3500 degrees, which meets the various needs of the engine. It is a piece of cake.
As for the three cores of the engine: high-pressure compressor, combustion chamber, and high-pressure turbine. The most critical core component of these engines, Rose could not make it alone. Before the Lantern Festival, he had designed these core components, and provided a large number of drawing technical parameters to General Xu.
Relying on the strength of AVIC, Chuanfei, Shenfei, Xifei, etc., coupled with the efforts of tens of thousands of scientists at the Space Center, the best experts in the country are concentrated, and manufacturing these components is not a problem.
Now Ross called General Xu's phone and asked General Xu about the development of engine core components.
When receiving a call from Ross, General Xu was very excited: "Major General Luo! These days, I'm almost dizzy. The drawings and technical materials you provided are too precious. On the day you got the drawings, the entire Ministry of Industry and Aerospace There is also the Ministry of National Defense, and everyone can't fall asleep. Every day, the leaders of the four major airlines were convened. People, formed a team of experts, and studied the technology overnight.
In order to develop engines, China has begun to focus on the strength of the country, concentrating all advantages, and is overcoming these difficulties. We have already tens of thousands of people on the front lines of major production lines. I believe it won't be long before we can come up with the key technologies of the core components you said. Ross, how about the leaves? The most important turbine fan blades you haven't figured out. "
Ross grinned: "The blades of the engine are not a problem for me. As long as you can get those core components, I will read UU Kanshu www.uukanshu.com single crystal blades to me, and soon I will send the finished blades to the national defense unit."
"Rose! I heard that you have made ceramic metal. Although this gadget is advanced and can be used as the blade material of the engine. But how to solve the problems of blade size, precision drilling, and precision machining machine tools?"
"Grandpa Xu, these problems are not a problem for me. You can keep busy. I'll get the blades done, and I'll call you again. Let's work together and hope that the domestic super engine will come out soon."
"Well, once the parts you said are successfully manufactured, I will call you immediately. Major General Luo! I must be busy, in order to get the engine earlier, I must supervise the work site. Goodbye!"
"Goodbye, Grandpa."
After I hung up the phone, Rose was relieved.
Huaxia's four major airlines, plus tens of thousands of experts from the aerospace department and major scientific research institutions, went to the four major aircraft manufacturing plants.
They only need to make it according to the drawings. The materials are made of their own special steel alloys. If they can't get the engine parts of those aircrafts, it can only be said that they are not saved.
Sitting in the office, Rose began to focus on the design of the engine blades. As long as these blades were designed, after the high-precision machine tools arrived, the engine blades could be manufactured.
Hua Xia is using the power of the whole country to cooperate with Ross to cure Hua Xia's heart disease. Once the super engine comes out, it will become a sign of Hua Xia's rise. (To be continued.)
