01 CMOS mmWave fully integrated 4-channel phased array chip
China has successfully developed CMOS mmWave fully integrated 4-channel phased array chip, and has also completed chip packaging and testing. According to , the development of the chip was publicly completed by Nanjing Network Communications and Security Purple Mountain Laboratory, which is a major technological breakthrough for my country's science and technology. China has broken the United States' monopoly on 5G millimeter wave technology and is no longer subject to others.
It is worth mentioning that the cost per channel of the 5G millimeter wave chip developed by my country is only 20 yuan, and the cost is only one-fifth of that of Qualcomm in the United States. You should know that the cost per channel of our chip has reached 1,000 yuan before. my country has made new breakthroughs in the research and development of millimeter-wave antennas. It has packaged a large-scale active antenna array with integrated 1024 channel antenna units. It is reported that the success of this new chip and antenna will be possible to be put into commercial use on a large scale in 2022 to help the completion of the 5G system. This breakthrough in 5G technology can be regarded as a technological breakthrough at the "shield machine" level for my country, which has great significance for my country's future 5G and even 6G technology. If China officially enters the 5G era, millimeter wave is a hard technology that cannot be avoided.
02 128-layer flash memory chip
The total amount of chips imported by China once reached half of the global chip import volume. There are many types of chips. The so-called integrated circuits generally refer to chips in semiconductor component products, which are mainly divided into two types: non-memory chips and memory chips. Among them, non-memory functional chips such as computer CPUs are much more difficult than memory chips, and naturally the price is also rising.
China has successfully broken the technological monopoly in the US chip field! China has conquered 128-layer flash memory chips and has begun to achieve full mass production. It is worth mentioning that the two chip fields of DRAM memory chips and NAND flash memory chips have been basically completely monopolized by the United States, Japan and South Korea, while the United States Intel and South Korea Samsung , Japan Toshiba and have core technologies and markets. It is worth mentioning that China Changjiang Storage Company once invested 7 billion yuan, and the R&D team conquered 32-layer 3D flash memory chips in just two years. It only took a very short time for China to complete the technology piled up by developed countries for decades, and gradually break this technical barrier, which is commendable.
03 Ethylene compressor technology
As a global superpower, the United States has been "bottled" by the United States many times. But with the development of our country, the United States' technological hegemony is gradually being broken. It is worth mentioning that the ethylene compressor technology that the United States has monopolized for 50 years has been conquered by a Chinese female engineer in 9 months. This technological breakthrough can help our country "save 200 million" a day. As an important large-scale people's livelihood project in China, the scale of the West-East Gas Pipeline Project has amazed all Western countries. In particular, ethylene compressors play an important role in the West-East Gas Pipeline Project. In order to ensure the transportation of natural gas for more than 4,000 kilometers, a million-ton ethylene compressor must be installed every 200 kilometers.
However, my country lacked million-ton ethylene compressors at that time and could only buy them from other countries. At that time, only the United States, Japan and Germany mastered this technology. Among them, the United States' General Electric Company is the first company in the world to build a million-ton ethylene compressor, and its technology is more advanced than the other two countries. my country has contacted GE in the United States to cooperate, but the United States is very arrogant in its attitude towards technology monopoly. It not only offers a high price of 10% higher than the national price, but also requires my country to pay it up to 200 million yuan in patent fees every day. The US's intention is also very obvious, which is to see that my country has a huge demand for ethylene compressors and take the opportunity to make a big profit.
million tons ethylene compressor is not a simple enlarged version of a small compressor. In the process of compressor large-scaleization, the first thing to overcome is the gas pressure and temperature that has increased geometrically. In addition, such a large-scale compressor must ensure that there is no leakage, otherwise it will cause immeasurable and terrible consequences. China finally broke through the technical bottleneck in 9 months.
04 Crude oil catalytic cracking technology
According to China Chemical Information Network , Exxon Mobil Corporation of the United States took the lead in setting a precedent for the COTC project as early as 2014, directly using crude oil to produce 1 million tons/year ethylene . It is worth mentioning that China has also made significant progress in this field. According to previous news from China Petroleum and Chemical News Network, the catalytic cracking technology independently developed by the China Academy of Petroleum and Chemical Engineering Sciences has successfully conducted industrial experiments, and this technology supports the direct conversion of crude oil into chemicals such as light olefins and aromatics.
It is worth mentioning that this is the first global industrial application of crude oil catalytic cracking technology. It not only means that China has broken through the United States' technology monopoly in this field, but also marks a breakthrough in my country's COTC technology and becomes the leader in this global technology route.
This technology can "skip" traditional oil refining and other processes, directly convert crude oil into the required substances, increasing the yield of high-value chemicals such as ethylene, propylene, . The experimental results show that after the successful application of this technology, the total yield of low-carbon olefins and light aromatics can be increased by 2 times, up to more than 50%.
1 The director of the Institute of Petrochemical Sciences once said that this technology has opened up a new way for crude oil-made chemicals, which is of great significance to resolving China's overcapacity of refining, ensuring the supply of chemicals and reducing carbon emissions; chemical yields are expected to reach up to 70%, which means that every 1 million tons of crude oil processed can produce about 700,000 tons of high-value chemicals.
05 RLV-T5 recyclable rocket
Chinese private aerospace enterprise Lingke Aerospace has made a major breakthrough in the technology of recyclable rockets. The latest RLV-T5 rocket they developed has excellent performance. Western experts once said that what they worry about the most happened. The rise of China's private aerospace will break the United States' monopoly in this field.
This rocket has a height of 8.1 meters and weighs 1.5 tons. Of course, this is just an experimental rocket and cannot directly launch any payload into space. The main purpose of RLV-T5 is to check its own structure and a series of operating algorithms used to allow this rocket to hover itself at a specified height and control itself to successfully land on a specified area. This can be seen that this work is very difficult.
06 Air-cooling tower technology
The air-cooling tower technology invented by the United States and Germany once subverted the world and also monopolized 60% of China's market. Mastering this technology is equivalent to controlling the market's voice. It is worth mentioning that the price of selling two 350,000 kilowatt air-cooling towers in the United States is very high. Not to mention equipment, the design fee alone required a high fee of 40 million to 50 million yuan. China began to strive to make progress while buying the US air-cooling tower and focusing on independent research and development. In less than two years, China broke through this key technology. China has also pioneered an anticorrosion technology in the world. Spraying a special layer of metal powder on the heat sink can achieve an anticorrosion effect of more than 30 years. It is worth mentioning that the first set of air-cooling equipment independently designed by China has been operating safely in North China for more than two years, and there is no gap between it and the United States and Germany.
In addition, Chinese scientists have developed the third-generation nuclear power technology "Hualong One" with independent intellectual property rights to avoid the crisis caused by the United States and Japan. The so-called air cooling tower is like a particularly large car water tank. The hot water releasing heat from the inside and the outside fan. This cooling technology uses air convection to cool down, and will not consume a lot of water resources. It is especially suitable for water-scarce areas.
07 Galaxy Kirin V10 system
China's Great Wall Computer has successfully created a PKS system based on "domestic CPU + domestic operating system + security", and all key core components have been domesticized. In April 2020, the first Great Wall domestically produced independent security computer equipped with Galaxy Kirin V10 system was launched. This computer only takes 10 seconds to start, and its performance and user experience are comparable to mainstream products.
China Great Wall was able to create a PKS system based on "domestic CPU + domestic operating system + security", which was the result of more than ten years of continuous investment and hard work. In 2020, Galaxy Kirin V10 system was selected as the "Top Ten Powers of the World" for central enterprises.
According to data released by relevant research institutions, as of June 2020, Microsoft Windows was the leader in the PC operating system field, with a global market share of more than 86%; the second place was Apple Mac OS, with a share of nearly 10%. These two American companies monopolize 95% of the global share of PC operating systems. Therefore, it is easy to be bored by the United States. Although the emergence of the Kirin system was unable to challenge Microsoft's dominance at that time, it was a domestic operating system developed by ourselves. It had broken the monopoly position of the US operating system in China, especially in the fields of office, finance, energy, transportation, etc., and therefore it deserved to be rated as the " national heavy weapon " by the central enterprise.
08 Rotary guide system and random drilling logging system
China's independently developed rotary guide system and drilling logging system jointly completed drilling operations in Bohai . These two technologies can guide drill bits to travel freely in hard rocks several kilometers underground and accurately hit the reservoir. These two technologies represent the highest level of drilling and logging technology in the world today. China has broken the monopoly of giants such as the United States in these two technical fields, becoming the second country in the world to own these two technologies at the same time China National Offshore Oil Corporation has also become the fourth and first domestic company to own these two technologies at the same time. It is worth mentioning that due to the difficulty of R&D, these two technologies have been monopolized by three American oilfield technology service companies for many years.
China's independently developed rotary guide system Wellleader® and drilling logging system Drilog® can independently complete the mining needs of offshore "cluster wells" and complex oil and gas layers, and is expected to significantly reduce the comprehensive cost of domestic oil and gas field development.
09 Purification of rhenium metal and manufacturing single crystal blades
Hran was explored in the mines of Huanglongpu Molybdenum Mine Area, Luonan County, Shaanxi Province, with a reserve of 176 tons, accounting for about 7% of the global reserves, second only to Chile , the United States, Russia and Kazakhstan . China discovered super metal, thus breaking the US monopoly in one fell swoop, and China's aviation industry achieved a qualitative breakthrough. The single crystal blades in aircraft engines are in the parts with the highest temperature, the most complex stress and the worst environment. They are the first key part of aviation products and directly determine the performance of aircraft engines. The core component of a 1,000 kg thrust engine center is 60 single crystal blades.
engine compresses the air and presses it into combustion chamber , causing violent combustion with the fuel in a limited space, generating a violent gas injection flow, pushing these blades to rotate at high speed, bursting out amazing power, and the horsepower output of each blade is equivalent to a 2.0-displacement SUV car. It is understood that the high-pressure speed of the 1,000 kilogram engine is more than 30,000 and nearly 40,000 rpm. The approximate tangential speed is about 450 meters per second, and the temperature is about 1,720 degrees.
In order to prevent melting, engineering and technical personnel made each blade hollow, and a precise and complex cooling system was designed in the middle. The heat taken away by the cooling system can boil a pot of water in 1/20th of a second or even less. However, at a high temperature of 1700 degrees, ordinary metals are still not heat-resistant enough. Therefore, the production of single crystal blades is inseparable from the precious rare metal - rhenium.
rhenium is the latest natural element discovered by humans. Its content in the earth's crust is smaller than all rare earth elements, making it more difficult to obtain than diamonds. The world's proven energy reserves are only about 2,500 tons. The parent company of a company in Chengdu, China, is able to purify gold metals. Chinese companies have overcome many difficulties and produced qualified single crystal blades.
10 Single-hole surgical robot
The single-hole surgical robot developed by China Jingfeng Medical has broken through the patent blockade of Da Vinci surgical robot in China, and carried out the first animal test of single-hole surgical robot in China as early as May 2018. It is worth mentioning that the Jingfeng Medical prototype has been iterated to the third generation and is expected to be launched on the market within two years. In addition to the original technology on the robotic arms, China Jingfeng Medical has independently developed the control panel, imaging system, and core algorithms of surgical robots, forming complete independent intellectual property rights.
Mits Institute of Technology's famous Da Vinci surgical robot was once the most successful and widely used surgical robot in the world, and it also represents the highest level of surgical robots today. In 2015, a video of Da Vinci's surgical robot peeling grapes was released on YouTube, which shocked everyone. Today's surgical robots can peel quail eggs without destroying the film, and no liquid leakage after suturing the 2mm ultra-fine hose.
11 3D printing technology
A technology in China has attracted great attention from the United States. This technology is 3D printing technology. At that time, the United States did not know when China had conquered this technology, because the United States had previously officially claimed that it was the only country in the world that mastered 3D printing technology. The United States believes that this technology is their global monopoly. It is worth mentioning that the 3D sand core printer developed by China has been mass-produced and will be used in the Fortune 500 Chinese and American oil and gas companies, ship heavy industry and other companies. China has undoubtedly become the first country in the world to industrialize 3D printing.
In addition, in the aerospace field, it is well known that rockets have thousands of core components, one of which is the propellant pump. It takes nearly 4 years to build such a component, because from design to drawing, then to review, then testing and production line manufacturing. Be careful in every step and every step. Because any error in any step may delay the launch of the rocket. China's 3D printing technology will solve these problems in the future. If 3D technology is applied to rocket parts manufacturing, the time will be shortened by at least half. Moreover, the quality is better than that produced by traditional processes and is more accurate.
12 Nuclear power plant C-type sealing ring
There are 4 very important safety barriers in nuclear power plant. The first barrier is high temperature, radiation and radiation-resistant uranium dioxide ceramic nuclear fuel, which is enough to block 98% of radioactive fission substances; the second barrier is a fuel rod composed of a clad tube stacked into a main body, which will not allow any radioactive fission substance to overflow under long-term operating conditions; the third barrier is a pressure vessel, ensuring that the fuel rod will not leak easily under high pressure operation; the last barrier is a double-shell structure factory with extremely high protection capabilities.
China's new monopoly technology to break through the United States belongs to part of the third barrier, namely "C-type sealing ring ". The function can refer to the rubber gasket used between the body and lid of the insulating water cup, which can greatly prevent internal substance leakage. It is worth mentioning that since the United States established the world's first nuclear power plant in 1951, it has firmly grasped nuclear power technology. Among them, the most important "C-type sealing ring" technology has been monopolized by the United States for nearly 50 years! The export price even reaches 150,000 yuan, and it takes at least 3,000 seals to build an nuclear reactor . It is conceivable how much profit the United States has made around the world.
13 R&D and manufacturing technology of aramid paper
China has achieved many achievements in science and technology in recent years that make the Chinese people proud. Among them, one of the important technology was monopolized by the United States for 50 years. China finally broke through and made the products of this technology a bargain again. It is the R&D and manufacturing technology of aramid paper. The so-called aramid refers to synthetic fibers made of aromatic compounds as raw materials, and aramid paper is a honeycomb composite material made of aramid synthetic fibers. The full name is polyaramide fiber paper.Although called paper, it is not used for writing, painting or printing, but is used as an insulating material, and structural material in the industrial and technological fields. In the aerospace field, heat-resistant insulation, extremely high strength and lightweight aramid paper can save a lot of power and fuel while maintaining safety and stability, greatly reducing manufacturing and use costs. Aramid paper is also an important military industrial material. For example, the inner cover of radar and some other military-industry stress-bearing structural components use aramid paper, which plays an important role in national defense materials.
It is worth mentioning that such a crucial material production technology has been monopolized by the United States for nearly 50 years. For example, in the 1960s, Nome Paper, the predecessor of aramid paper, was invented in the United States, and through continuous technological improvements, it eventually became today's aramid paper.
China's outstanding research in the field of electromagnetics has made it possible to realize Chinese aircraft carrier in electromagnetic catapult . In contrast, although the United States began to develop the electromagnetic catapult technology very early, there are still various problems with the electromagnetic catapult device on the US Ford aircraft carrier. Trump even proposed to remove all the electromagnetic catapult on the US Ford aircraft carrier and replace it with ordinary steam catapults. China's electromagnetic catapults are much more advanced than the ones used by the United States on the Ford class . Although the US electromagnetic catapult has been put into service with the USS Ford aircraft carrier, due to various faults and problems in the USS Ford aircraft carrier, the USS Ford aircraft carrier has so far only an helicopter aircraft carrier and cannot carry the fighter . After all, the catapult problems are so many that the military dare not use it easily.
14 Supercontinuous spectrum light source
China Hou Jing's R&D team has broken through a number of key technologies and successfully developed two metal photonic crystal fibers, breaking the United States' leading position in the field of "supercontinuous spectrum light source". This technology can be used in civil use or converted into combat power, which is what we commonly call " laser ". In the field of lasers, the United States and the Soviet Union conducted research very early. The Soviet Union built the world's first laser platform in 1981, but with the disintegration of the Soviet Union, laser research has come to a standstill, and Russia has only developed a set of short-range laser emitters. The United States already has its own laser air defense system, and as the power increases, the fighter jets that can be destroyed will become larger and larger. The supercontinuous spectrum light source developed by China is a future technology that is more powerful than lasers.
15 The independently developed carbon-based chip
The United States has previously restricted the chip supply of Huawei , making us realize the importance of independence and independence of domestic chips. Although there is a big gap between China and the top internationally in silicon-based chips, it is gratifying that the carbon-based chip independently developed by China has successfully made important breakthroughs, and compared with traditional silicon-based chips, it has lower power consumption and cost and stronger performance. After the research and development of silicon-based semiconductors gradually entered a bottleneck period, the future development direction of global semiconductors is most likely to be carbon-based semiconductor technology. China is now leading the way in achieving technological breakthroughs in the field of carbon-based semiconductor technology, which can not only improve my country's position in the future semiconductor industry, but also of great significance to the world's scientific and technological progress.
Peking University Academician Peng Lianmao and Professor Zhang Zhiyong and others published a paper in the top academic journal Science, which is an important achievement in this field. Many media reports that this is expected to lay the foundation for carbon-based semiconductors to enter large-scale industrialization and also provide huge potential for China's chip industry to overtake. It is worth mentioning that there is no requirement of three types of line arrangement, high density and high purity in the world that can be achieved at the same time. Some experiments can achieve high density, but not high purity. Some experiments have high purity but no high density. Therefore, the performance of carbon nanotube transistors is always at least one order of magnitude worse than silicon. China has proposed a new preparation method, and for the first time, these three conditions were realized simultaneously. Therefore, for the first time in history, carbon nanotube transistors with performance exceeding silicon have been created.This is a milestone achievement, as commented on the official WeChat article of Peking University , it will lay the foundation for carbon-based semiconductors to enter large-scale industrialization.
16 Key technologies for semi-submersible lifting pipe laying ships
China National Offshore Oil Corporation A news came before that the group company-level scientific research project "Research on key technologies for semi-submersible lifting pipe laying ships" undertaken by the National Offshore Oil Engineering was completed and accepted. It marks that China has mastered the key design and construction technology of semi-submersible lifting pipe laying ships, breaking the technological monopoly of developed countries such as the United States, and filling the gap in this technology in China.
Semi-submersible lifting pipe laying ship is an offshore operation platform that can carry out deep-water vertical pipe laying and large-scale structure lifting operations. It is a top-level marine engineering equipment with comprehensive functions and excellent operating performance.
Before China's offshore pipe laying operation was made by butt welding of a single pipeline, and then placed into the sea through pipe laying ship and floated into the sea. That is, the "S-Lay" pipe laying method, which belongs to horizontal laying and is the most commonly used pipe laying method in the world. The semi-submersible lifting pipe laying ship adopts the "J-Lay" pipe laying method, which can vertically lay sea pipes into the seabed. Compared with "S-Lay", the "J-Lay" has a high tension, a larger pipe diameter and deeper laying water, and is more suitable for laying complex subsea pipelines with larger curvatures.
National Oil Corporation independently completed the basic design and construction plan of the equipment, and successfully passed the review and model test verification of the US Classification Society and China Classification Society .
17 Tire Pressure Monitoring (TPMS) Special Sensor Chip
At the 2020 China IC Leader Summit and China IC Design Achievement Award Ceremony, which is known as the "Semiconductor Industry Wind", Jiefa Technology won the "Five China Potential IC Design Companies", and Jiefa Technology's independently developed tire pressure monitoring (TPMS) special sensor chip AC5111 won the "Best Sensor/MEMS Product Award of the Year".
As one of the main representative companies in the domestic chip industry, the in-vehicle infotainment system (IVI) chip independently developed by Jiefa Technology has maintained its leading position in the domestic automotive after-installation market for many years, and this time, the AC5111 chip, which won the "Best Sensor/MEMS" product, is the first domestically produced automotive tire pressure monitoring (TPMS) dedicated sensor chip that uses fully integrated design technology solutions to mass-produce by the end of 2019. It marks a major technological breakthrough in the field of automotive MEMS in China's independent brand IC design companies and gradually align with top international chip design companies. It is worth mentioning that in the field of automotive tire pressure monitoring sensor chips, almost all European and American manufacturers have monopolized the market. As the world's largest automobile manufacturer and consumer, China is expected to usher in explosive growth.
18 Ultra-large forging manufacturing technology
China First Heavy has successively established topics such as "shortening manufacturing process, accelerating cylinder output" and "curing head sealing operations, ensuring output time nodes", which have achieved remarkable results in reducing manufacturing costs, compressing production cycle , and improving product quality, creating considerable economic benefits. Among them, the topic of "shortening the manufacturing process and speeding up the output of cylinders" is to shorten the heating time by at least 9 hours, and each cylinder saves 3,600 yuan. The 108 hydrogen cylinders produced save a total of about 400,000 yuan. The conventional island low-pressure rotor ingot weighs 715 tons. Faced with such a huge steel ingot, China First Heavy will scientifically arrange the use order and operation method of the equipment before each forging, and cleverly use other accessories to complete the forging while ensuring process requirements. With the successful forging of a number of super-large forgings such as 715-ton conventional island low-pressure rotor, 7.6-meter super-large transition section, 9-meter super-large cylinder section, it not only enhanced China's first-level manufacturing strength, but also broke the long-term monopoly of large forgings in developed countries in the United States, and won international voice for China in the field of super-large forgings.
19 early warning satellite key technologies
China has carried out a series of space experiments on key technologies related to early warning satellites through the practice series, the Fengyun series and other scientific experimental satellite , including a high-sensitivity hemisphere resonant gyroscope required for high-precision attitude control and high-orbit inertial navigation measurement, a multi-band broadband high-speed data processor for remote rapid information transmission, push-scan infrared optoelectronic chips and array devices, a gaze-type infrared chips and array devices, and a photoelectric combination detection system that verifies large-space target detection and recognition, rapid fusion of multi-sensor information, all-weather continuous tracking measurement, high-precision distance measurement angle, long-distance accurate imaging and other photoelectric combination detection systems, which have overcome one roadblock after another.
Chinese technical team successfully developed short-wave and medium-wave single-chip 2.7K×2.7K infrared focal plane detectors, which belongs to the third generation of ultra-large surface array high-sensitivity refrigeration infrared detectors . It not only fills the gap in my country in this field, but also reaches the top international level. The infrared focal plane detector is the core component of the early warning satellite infrared imaging system, and it is extremely difficult to develop. At present, only the United States in the world developed a 4K×4K product in 2009, and France developed a 2K×2K product in 2017. China Electronics Technology launched a 2.7K×2.7K product, making my country firmly ranked second after the United States. During the Cold War, due to the continuous escalation of the nuclear arms race between the two superpowers of the United States and the Soviet Union, ballistic missiles equipped with nuclear warheads, especially intercontinental ballistic missiles, , became the absolute main force of nuclear deterrence. In order to promptly discover the possible preemptive strike against nuclear strike against by the other party, so as to ensure that their side has enough reaction time, the United States and the Soviet Union have spared huge sums of money to establish a complete strategic early warning system. Early warning satellites deployed in space are a crucial and indispensable key component of this system.
20 austenitic stainless steel giant ring forgings
China has made a major new breakthrough in the field of special steel technology, breaking through the United States' monopoly for half a century in one fell swoop. Its importance is not even inferior to 5G at all. This technology is austenitic stainless steel giant ring forgings. The world's largest diameter rolling ring has been successfully developed in China. Its diameter reaches 15.8 meters and its weight reaches 150 tons. For this large steel structural parts in the world, integrated casting or segmented welding methods are often used. The casting method only requires making the mold first, then injecting the molten iron into the mold, and waiting for cooling. However, this relatively primitive casting method cannot ensure the quality of the metal ring. Because it contains a lot of impurities and is prone to rust, this process has been gradually eliminated. The welding method is to first make various segments of the metal ring, and then weld these segments together by welding process to obtain a complete circle. Since each segment can be obtained by forging, the metal performance has been greatly improved.
21 Unmanned electric wheel mine car
The "big Mac" successfully developed by China - Northern Shares newly developed NTE120AT unmanned electric wheel mine car. It is worth mentioning that driverless mine car technology is a high-end technology throughout the world. The research and development of the first domestic mine car completed by China has brought China's intelligent manufacturing smart products to a new level, and now it has the strength to compete with international giants. The first 110-ton NTE120AT unmanned electric wheel mining car developed by China Ordnance North Group North Co., Ltd., was successfully launched in China recently, making China the third country to be involved in the unmanned driving technology of mining vehicles after the United States and Japan. Northern Co., Ltd. uses artificial intelligence technology to develop mining car products covering cutting-edge technologies such as intelligent navigation, precise positioning, and safe driving, achieving a breakthrough in autonomous driving technology.
22 Digital fly-by-wire flight control system
The three-axis and four-degree digital fly-by-wire flight control system used by China's "J-10" fighter is a typical control system used in fighter jets. Its function is to ensure that the aircraft remains stable when the pilot pulls the rod.China has successfully developed the third-generation telex flight control system, which should be said to have broken the technological monopoly of the United States, Russia and France, but it is only the first step that has been completed in the Long March.
23 cutting-edge impeller processing technology
China has become the only country except the United States that masters cutting-edge impeller processing technology. It is worth mentioning that the West-East Gas Pipeline is 4,200 kilometers long, and the first-line and second-line projects alone have radiated to 15 provinces across the country, benefiting over 400 million people. It can reduce carbon dioxide emissions by 200 million tons and sulfur dioxide emissions by 2.26 million tons each year. Since the technology of the core part of the gas pipeline, namely the large compressor unit, is in the hands of General Electric in the United States, this major project that concerns the national economy and people's livelihood is also subject to some extent. Every day of shutdown, at least 200 million yuan will be lost. It is reported that the West-East Gas Pipeline needs a large pump station to pressurize every 200 kilometers. If this cutting-edge equipment cannot be domestically produced, it will always be a trump card in the hands of the United States. In fact, the impeller of the compressor unit is the real core problem. Due to the extremely difficult technology, General Electric has achieved high monopoly profits for 50 consecutive years.
24 Yangtze River-1000 aircraft engine
The United States has the world's advanced engine development technology. After years of struggle, China has finally achieved success in engine technology and has made new breakthroughs in 2021. The Yangtze-1000 aircraft engine is a representative of new technological breakthroughs. Its emergence broke the United States' monopoly blockade of my country's science and technology. The phased achievements of the Yangtze-1000 mean that my country has broken through the United States' core technology blockade and is no longer imprisoned by the United States. It is worth mentioning that China has been preparing for the development of the C919 engine since May 2017, and it was only successfully ignited in May 2018. The C919 engine, the Yangtze-1000, has achieved phased results, completely solving the material process problems of turbine blades. It uses a brand new casting process, which means that the blades of the Yangtze-1000 will be thinner, more high-temperature resistant, and more wear-resistant, leading the way than all current aircraft engine blades.
The biggest feature of the independent research and development of the Yangtze River is de-Americanization. At that time, my country's C919 aircraft was criticized because its core engine was made in the United States. Therefore, my country is now working hard to de-Americanize the engines it developed so that no part of the engine or aircraft is made in the United States.
25 Holographic Sighting Technology
China has successfully broken through the monopoly of the United States. The team was led by Professor Liu Shou of Xiamen University. With the strong support of the country for this technology, it finally independently developed and built the holographic sighting , which belongs to China in 2000. Holographic scopes are not affected by the environment. When shooting, you no longer need to stare at it with your eyes all the time, and not only makes shooting simple, but also greatly improves shooting accuracy. Previously, the United States used this technology, the United States' holographic scopes were sold all over the world, allowing them to make a fortune. The so-called holographic technology is familiar to you, for example, when watching 3D movies in the theater, it uses holographic projection technology. But why can’t other countries in the world create holographic scopes? The main difficulty is that Americans can infinitely miniaturize holographic technology until it can be used on ordinary guns. Although holographic scopes were used on fighter jets as early as the 1970s and 1980s, it was not until the end that Americans developed miniaturized holographic scopes that could be used on ordinary firearms. Therefore, China's breakthrough is really valuable.
