The Made in China 2025, published by the State Council, lists aviation equipment as an important breakthrough target for the next decade. Among aviation equipment, the most concerned is the aero-engine. The aviation industry is compared to the modern industry "Crown" , the aviation engine is called the modern industry "The Crown Jewels" , is the airplane heart. For a long time, some people do not understand, why China can build Shenzhou spacecraft, built the j-10 fighter, but not an advanced aero-engine? How hard is it to develop an aeroengine? How can China make breakthroughs through indigenous innovation? The reporter did an interview. What's so hard about it? It's above 1,700 degrees Celsius, and the bottom pressure of the Three Gorges Dam, which is three times as much as the full water. "The aeroengine is a technique of approaching the limit in the engineering application of classical mechanics, and has its own extraordinary difficulty. Specifically, the aero-engine is a thermal machine which provides power for the aircraft. It needs to work under high temperature, high pressure and high speed of rotation, and the requirements for development are very high,"said Pang Wei, general manager of AVIC. How hot is it? At present, the working temperature of advanced aero-engine is over 1700 °C, which is much higher than the melting point of nickel-based Alloy for turbine blades. How stressful is it? The pressure of the engine compressor after pressurization can reach more than 50 atmospheres, which is equivalent to three times the bottom pressure of the Three Gorges Dam after it is filled with water. How fast does it spin? The rotor spins tens of thousands of times per minute, and the centrifugal force on the tip of the blade is equivalent to the pulling force of a 40-ton truck. Some people think that high temperature, high pressure, high speed of rotation is of course a high demand for development, but the spacecraft will not also face the problem of high temperature? Doesn't marine equipment deal with high pressure? Why is aeroengine development stuck? High temperature, high pressure and high speed, Pang explained, can indeed be solved by some technical means on their own. For example: spacecraft, rockets, can be covered with heat insulation tiles at high temperatures to solve high temperature problems; ground and water power, can make the engine a little larger to solve the pressure, strength problems; one-off products, such as missile power, rocket power, no need to think about long life, some problems will be solved, and finally burned or no longer use on the line. However, the aero-engine is not the same, and its development and "small size, light weight, long life, can be reused" requirements, which means that the difficulty multiplied. "An aero-engine is designed to maximize its performance under these stringent constraints. Understanding these characteristics will help you understand why it is so difficult to develop an aero-engine, " Pang said. The aircraft engine is compared to the modern industry "The Crown Jewels" , partly because its development concentrates the modern industry most cutting-edge technology, the most advanced industrial results. As a result, the level of aero engine development is also a concentrated reflection of a country's Comprehensive National Power, industrial base and scientific and technological level. If a country in part of the technical links, part of the industrial sector there is a short board, it will restrict the development of aero-engines. For example, if the materials industry can't come up with the Best high-temperature materials, engines won't perform as well. The precise electronic components used in aero-engine need to be developed by other industrial departments. If this aspect can not be broken through, it will affect the performance of aero-engine. "At present, there are many countries in the world that are capable of handling rockets, missiles and nuclear bombs, and there are also more than a dozen countries that are capable of handling aircraft. But only the United States, the United Kingdom, Russia, France and other countries can really do aero-engines. "If you can't keep up with the Comprehensive National Power, the industrial base and the technological level, you won't be able to build an advanced engine, " Pang said. Why so much money is needed. AEROENGINES are not only designed, built, but tested. Trial and error, similar to "burning money" not long ago, Lin Zuoming, chairman of the Aviation Industry Corporation of China, said that the lack of investment was one of the main factors limiting the breakthrough of aero-engines. The claim was immediately controversial. Some people think, can not do to say is the money thing, is it really less money does not work? The reporter understands, the country that can produce aeroengine, the capital that invests on this one project is really a lot, and duration is longer. According to statistics, over the past 50 years, the United States has spent more than 100 billion dollars on aircraft engine research and development. The F119 engine, which is equipped with the 4th generation f-22 aircraft in the United States, has spent 32 years from initial component research to full operational capability. In these countries, the main body of research and development is enterprises, but a large amount of investment comes from the government. Governments often invest directly in the development of military engines, and the technology acquired is transferred indirectly to the field of civilian engines. The government has also invested heavily in basic research and applied technologies for aero-engines. What are you going to do with all this money? 'The aero-engine is not only designed, not only built, but also tested, ' Lin said. Trial and error, to some extent, is equivalent to "burning money. ". The development of aero-engine must rely on a great deal of empirical data. Because of the particularity of aviation equipment, these data can only be obtained by self-test. It is necessary to purchase raw materials, process test pieces, develop test equipment, study test technology, and consume a lot of materials and energy in the test process itself. After the aeroengine is designed and manufactured, a large number of tests have to be carried out to fully expose the problem. Many tests must be done according to the development procedure and specification, including parts test, parts test, system test, core machine test, whole machine test, etc. . Among them, the whole machine test will do thousands of hours, or even tens of thousands of hours, is really in the "burning" engine. A high-thrust engine burns more than ten tons of kerosene an hour. Some people will ask, can't we burn less for a while? It is understood that according to the specifications, some performance indicators, such as fatigue life, test cumulative less than a certain number of hours, it is impossible to know whether the standard is not met. The problems revealed by the experiment should be continued after the improvement. Some tests are destructive and require the destruction of parts or machinery. If the TURBINE DISK rupture test, do it on the scrap, and do it is dozens of disk, because to accumulate data. Another example is the fan containment test and bird strike test in civil aircraft engines, which require the destruction of the entire engine. These tests are required by airworthiness system and design system in order to ensure flight safety.
