德国为何欲购中国航空发动机技术 张召忠解读内情
德国为何欲购中国航空发动机技术 张召忠解读内情

根据香港《南华早报》报道，一名参与谈判的科学家透露：中国和德国正在讨论向德方出售喷气式飞机引擎关键加工设备和技术，由于这个消息太敏感了，正参与相关磋商的这名科学家是匿名接受采访的。
珠海航展上展示的国产引擎
这位科学家说：“来自西安的飞机发动机的生产基地派出一个代表团，将于今年早些时候访问柏林，与德国同行起草出口建议。”咱们国家的西安市阎良区那里有大名鼎鼎的西飞集团，很多民用、军用飞机都是在那里生产的。
据悉，这次出售清单中，有能加工涡轮叶片的高端精密设备，制造出的涡轮叶片能够承受的温度比所用合金熔点还要高出几百摄氏度。
涡轮叶片
对于喷气式涡轮发动机来说，涡轮叶片绝对是最关键的部分之一。打个比方，航空发动机被誉为现代工业的“皇冠”，那么涡轮叶片就是“皇冠上的明珠”，因为它处于航空发动机温度最高、应力最复杂、腐蚀最严重、环境最恶劣的部位。
涡轮叶片工作示意图
之前我国飞机发动机制造技术上与西方发达国家仍存在较大差距，重大瓶颈问题就是发动机的推力严重不足，为提高发动机推力，就需要发动机的涡轮叶片能够承受更高的温度。
随着我们国家突破单晶高温合金、复杂曲面超精细冷加工等一些列关键技术，中国逐渐开始生产出新的高性能军用和民用喷气发动机，之前做过一期文章专门讲了国产大飞机C919也有望换上中国心。
德国曾经是世界上第一个制造出喷气式战斗机的国家，现在要向中国购买喷气式发动机相关技术，应了那句老话：三十年河东，三十年河西。
二战末期德国HE-162火蜥蜴战斗机
但是，根据另外一位曾经在德国工作多年的喷气发动机科学家说：“德国是北约成员国、美国的盟友，现在想跟中国在这个敏感技术领域进行合作势必将面临诸多限制。”这一项目还存在变数，不排除美国可能从中作梗，但至少从侧面印证了中国航空发动机领域的长足进步。
曾经西方和美国对中国重重封锁，特别是发动机这种关键技术，门都不让你碰一下。我国发动机也长期落后于人，只能从俄罗斯和乌克兰大量进口。
著名的乌克兰马达西奇公司
现在乌克兰与中国合作建厂共同生产涡扇20、D-18T大涵道比涡扇发动机等。与此同时俄罗斯也积极与中国联合生产宽体客机C929、联合研制大型客机发动机和其它战机发动机，德国想和咱们合作一点也不奇怪。
提起德国，很多人第一印象就是这个民族很严谨，不浮躁，有工匠精神，确实德国制造享誉全球，奔驰、宝马、奥迪、保时捷这些汽车品牌在中国影响力很大。
但互联网上也存在着过分夸大、神话德国制造的段子，比如“青岛下水道存放百年德国油纸包”，“兰州铁桥百岁时收到来自德国的提醒信和维修配件邮包”，这些谣言被人们广为流传。小编高中写议论文时候也用“德国油纸包”做过论据，后来才知道是网友编的段子。
神话德国制造也就算了，还有恶意的键盘侠混淆是非，抹黑中国制造：
这张图是国外传过来的，一个自行车和小轿车撞了，自行车没事，小轿车前面撞出个坑。有不怀好意的人就编段子说这自行车是德国生产的，质量好，那小轿车是中国的，连“奥迪美国”的Google+页面都转发过这张图，在国外印象力很大。实际上那辆自行车是地道的中国制造！是天津一家企业生产的~
实事求是的讲，中国制造业距离美国、德国等制造业强国还有一定距离，但随着中国全方位的崛起，产业从量变到质变，技术不断创新迭代，类似这种西方国家找上门来跟我们合作的新闻还会越来越多！（作者署名：局座召忠）

据美国《国家利益》双月刊网站8月26日发布的题为《中国空军很强大，但发动机是个大问题》的文章称，即使在今天，喷气式发动机仍是人民解放军空军对战斗机进行更新换代的一大障碍，其早期推出的第5代原型机明显动力不足。使问题进一步复杂化的是，对于向中国提供比AL-31型发动机（用于为苏-27飞机提供动力）更强大的发动机，俄罗斯现在持谨慎态度。但中国也有多种途径来解决这个问题。
文章认为，最明显的选项就是制造更好的国产发动机。2016年，中国“十三五”国家战略性新兴产业发展规划强调了提高国产喷气式发动机设计性能和进一步发展航空航天工业的重要性。目前看来至少已取得一些成功，如最新的歼-20原型机使用的是升级版的WS-10发动机，据称这种发动机的隐形性能及动力均强于AL-31发动机。虽然民营企业成都航宇超合金技术有限公司最近在涡轮风扇技术方面取得巨大进步，由此可生产出更高效的发动机，但这一技术突破带来的成果尚未惠及人民解放军空军前线部队。

文章称，此外，更简单的办法是购买配有先进发动机的外国战斗机，如人民解放军空军从俄罗斯购买了苏-35飞机。苏-35飞机使用的AL-41F1S发动机是一款动力极强的推力矢量发动机，相比AL-31发动机实现了巨大飞跃。虽然中国起初曾对ALS-117发动机这一独立产品表示出兴趣，但俄罗斯拒绝单独出口这款发动机，中方由此需要采购苏-35战机。

文章评论称，中国此前在研制WS-10发动机方面面临诸多困难，这表明，获取外国发动机的设计并不会立即转化为可生产出同等质量的发动机。此外，中国同意履行对俄罗斯知识产权的保护，如果做不到的话，中国未来在获取俄罗斯先进武器系统方面就会受限。然而，美媒认为，对俄罗斯军火工业前景的悲观预测可能会迫使它反其道而行之，因为失去中国市场准入权将给俄罗斯造成沉重打击。俄罗斯的影响力也在不断减弱；随着中国技术和工业基础的改善，从俄罗斯实施进口的重要意义在不断下降。
文章认为，中国也可以将其蓬勃发展的民用飞机产业作为获取军事应用的跳板。毫无疑问，这样做有多种好处。侧重发展民用航空可为与西方公司合作提供更广阔的机会，同时也为中国航空技术打开了新的出口市场。例如，德国有意购买中国制造的涡轮叶片，据说在许多方面都优于德国设计。此外，这样做还能满足国内需求，中国是世界第一大民用飞机市场。然而，欧美企业在技术转让方面受到严格限制，由此削弱了它们提供有用信息的能力。
图为歼-10A战斗机
文章称，尽管存在上述巨大障碍，中国在军事航空领域仍在快速取得进步，中国也不大可能永远在发动机技术上处于落后地位。3D打印技术的进步可能为它提供一种快速实现喷气式发动机制造、样机验证及开发的途径。然而，虽然世界各国军队已在使用3D打印技术生产飞机及舰船零部件，但尚未用3D技术生产出现代化的军用级别的涡扇喷气式发动机。鉴于此类任务的内在复杂性，这种技术可能需要多年时间才能足够成熟以便进行推广。就目前而言，如果中国要掌握战斗机发动机的设计，进而最大限度地提高该国空军的作战效率的话，那么它就必须作出艰难抉择。（编译/王超）

According to Hong Kong's "South China Morning Post" report, a scientist involved in the negotiations revealed that China and Germany are discussing the sale of key processing equipment and technology for jet engines to Germany. Because the news is too sensitive, the scientist who is participating in the consultations. It was interviewed anonymously.
The domestic engine displayed at the Zhuhai Air Show said: "A delegation from the production base of aircraft engines from Xi'an will visit Berlin earlier this year to draft export proposals with German counterparts." Xi'an City, our country There is a famous Xifei Group in the good area, where many civilian and military aircraft are produced.
It is reported that in this sale list, there are high-end precision equipment capable of processing turbine blades, and the turbine blades can be manufactured to withstand temperatures several hundred degrees Celsius higher than the melting point of the alloy used.
Turbine Blades Turbine blades are one of the most critical parts of a jet turbine engine. For example, the aero engine is known as the "crown" of modern industry, then the turbine blade is the "crown jewel" because it is in the highest temperature, most complex stress, the most corrosive, and the worst environment.
Before the turbine blade working diagram, China's aircraft engine manufacturing technology still has a big gap with the developed countries in the West. The major bottleneck problem is that the thrust of the engine is seriously insufficient. In order to improve the engine thrust, the turbine blades of the engine can be subjected to higher temperatures.
As our country breaks through some key technologies such as single-crystal superalloys and complex curved surface ultra-fine cold processing, China has gradually begun to produce new high-performance military and civilian jet engines . Previously, we have written an article on the domestically produced large aircraft C919. It is expected to be replaced by the Chinese heart.
Germany used to be the first country in the world to make jet fighters. Now it wants to buy jet engine related technology from China. It should be an old saying: Hedong in 30 years and Hexi in 30 years.
German HE-162 Salamander fighter at the end of World War II However, according to another jet engine scientist who has worked in Germany for many years, "Germany is a member of NATO and an ally of the United States. Now I want to cooperate with China in this sensitive technology field. There are many restrictions. "There are still variables in this project. It is not excluded that the United States may be stalking from it, but at least from the side, it has confirmed the great progress in the field of Chinese aviation engines.
Once the West and the United States imposed a heavy blockade on China, especially the key technology of the engine, the door did not let you touch it. China's engines have also lagged behind people for a long time and can only be imported from Russia and Ukraine.
The famous Ukrainian Madic company is now cooperating with China to build a factory to produce turbofan 20 and D-18T large bypass ratio turbofan engines. At the same time, Russia is also actively cooperating with China to produce the wide-body passenger aircraft C929, jointly developing large passenger aircraft engines and other fighter engines. It is not surprising that Germany wants to cooperate with us.
When it comes to Germany, many people have the first impression that this nation is very rigorous, not impetuous, and has the spirit of craftsmanship. It is indeed famous for its manufacturing in Germany. The automobile brands such as Mercedes-Benz, BMW, Audi and Porsche have great influence in China.
However, there are also exaggerated and mythical German-made pieces on the Internet, such as “Qingdao sewer storage for centuries German oil-paper bags”, “Lanzhou Iron Bridge received a reminder letter from Germany and repair parts parcels when the hundred-year-old”, these rumors were widely For the sake of circulation. Xiaobian High School also used the "German oil-paper package" to make arguments when writing the papers. Later, it was known that the netizens compiled the paragraphs.
The myth is made in Germany, and there is a malicious keyboard man who confuses right and wrong, smearing China made:
This picture was passed abroad. A bicycle and a car crashed, the bicycle was fine, and a small car crashed into the front of the car. Some unscrupulous people said that the bicycle was made in Germany and the quality was good. The car was made in China. Even the Google+ page of "Audi America" has forwarded this picture, which is very impressive abroad. In fact, the bicycle is authentic in China! It is produced by a Tianjin company~
Practically speaking, China's manufacturing industry is still far away from the manufacturing powers such as the United States and Germany. However, with China's all-round rise, the industry has changed from quantitative to qualitative, and technology continues to innovate and iterate. This kind of Western country is looking for us to come to us. The news of cooperation will be more and more! (Author's signature: Bureau of the call)

According to an article published on August 26th of the US "National Interests" bimonthly website entitled "The Chinese Air Force is very powerful, but the engine is a big problem", even today, the jet engine is still the replacement of the fighter jet by the People's Liberation Army Air Force. A major obstacle, the early launch of the 5th generation prototype is obviously underpowered. Further complicating the problem is that Russia is now cautious about providing China with a more powerful engine than the AL-31 engine used to power the Su-27 aircraft. But China also has many ways to solve this problem.
The article believes that the most obvious option is to make better domestic engines. In 2016, China's “13th Five-Year” National Strategic Emerging Industry Development Plan emphasized the importance of improving the design performance of domestic jet engines and further developing the aerospace industry. At present, it seems that at least some success has been achieved. For example, the latest 歼-20 prototype uses an upgraded version of the WS-10 engine, which is said to have better stealth performance and power than the AL-31 engine. Although privately-owned Chengdu Aerospace Superalloy Technology Co., Ltd. has made great progress in turbofan technology recently, it can produce more efficient engines, but the results of this technological breakthrough have not yet benefited the People's Liberation Army Air Force frontline troops.
The picture shows China's self-developed "Taihang" engine article said that, in addition, the easier way is to buy foreign fighters equipped with advanced engines, such as the People's Liberation Army Air Force purchased the Su-35 aircraft from Russia. The AL-41F1S engine used in the Su-35 aircraft is a highly powerful thrust vector engine that has achieved a huge leap compared to the AL-31 engine. Although China initially expressed interest in the independent product of the ALS-117 engine, Russia refused to export the engine separately, and China needed to purchase the Su-35 fighter.
The picture shows that the J-20 fighter article commented that China had faced many difficulties in developing the WS-10 engine. This shows that the design of acquiring foreign engines will not be immediately converted into an engine of the same quality. In addition, China agrees to implement the protection of Russian intellectual property rights. If it does not, China will be limited in its future access to Russia's advanced weapons systems. However, the US media believes that the pessimistic forecast of the prospects of the Russian arms industry may force it to do the opposite, because losing the Chinese market access rights will cause a heavy blow to Russia. Russia’s influence is also waning; as China’s technological and industrial base improves, the importance of importing from Russia is declining.
The article believes that China can also use its booming civil aircraft industry as a springboard for military applications. There is no doubt that this has multiple benefits. Focusing on the development of civil aviation can provide a broader opportunity for cooperation with Western companies, while also opening up new export markets for Chinese aviation technology. For example, Germany intends to purchase turbine blades made in China, which is said to be superior to German design in many respects. In addition, this can also meet domestic demand, China is the world's largest civil aircraft market. However, European and American companies are severely restricted in technology transfer, thereby weakening their ability to provide useful information.
The picture shows that the 歼-10A fighter article said that despite the above-mentioned huge obstacles, China is still making rapid progress in the military aviation field, and China is unlikely to be in a backward position in engine technology forever. Advances in 3D printing technology may provide a way to quickly implement jet engine manufacturing, prototype verification and development. However, although military forces around the world have been using 3D printing technology to produce aircraft and ship parts, they have not yet produced 3D modern turbofan jet engines. Given the inherent complexity of such tasks, this technology may take many years to mature enough for promotion. For now, if China wants to master the design of the fighter engine and thus maximize the operational efficiency of the country's air force, then it must make difficult choices. (Compile / Wang Chao)

For example, Germany intends to purchase turbine blades made in China, which is said to be superior to German design in many respects. In addition, this can also meet domestic demand, China is the world's largest civil aircraft market. However, European and American companies are severely restricted in technology transfer, thereby weakening their ability to provide useful information.
The picture shows that the 歼-10A fighter article said that despite the above-mentioned huge obstacles, China is still making rapid progress in the military aviation field, and China is unlikely to be in a backward position in engine technology forever. Advances in 3D printing technology may provide a way to quickly implement jet engine manufacturing, prototype verification and development. However, although military forces around the world have been using 3D printing technology to produce aircraft and ship parts, they have not yet produced 3D modern turbofan jet engines. Given the inherent complexity of such tasks, this technology may take many years to mature enough for promotion. For now, if China wants to master the design of the fighter engine and thus maximize the operational efficiency of the country's air force, then it must make difficult choices. (Compile / Wang Chao)
