The complexity of the aero-engine is evident
For aviation engine, has been regarded as the "industrial pearl", and this pearl around the world, can be said to find their own good, is from the three: GE, Rolls Royce (Rolls-Royce) Company and Pratt & whitney. But there are military fans to ask, Russia as today's second largest military power, just after the United States, why is it manufactured engines failed to list it? The reason why we all know, Russia's aircraft engines, regardless of reliability or life expectancy, are far less than the western counterparts of the same kind of engine. Our country, because it can not get the advanced engine of western countries for a long time, is suffering from the short life and the suffering of reliability.
航空发动机的复杂程度可见一斑

对于航空发动机,一直被各国视为“工业明珠”,而这颗明珠放眼全世界,能够说自己找的好的,绝对是出自这三家:GE、罗罗(劳斯莱斯)公司和普惠公司。但有军迷要问,俄罗斯作为现今第二大军事强国,仅仅是排在美国之后,为什么它制造的发动机没能上榜呢?原因想必大家都知道,俄罗斯的航空发动机无论可靠性还是寿命都远远不如西方国家的同类发动机。我们国家因为长期得不到西方国家的先进发动机,所以也是饱受寿命短、可靠性之苦。

In fact, Russia to the Soviet Union is the engine has not been built well. So what is the reason why the Russian Airlines are limited for a long time? What can China learn from it?
As is known to all, Germany is located in Europe with heavy industry. In all aspects of heavy industry, Germany is the world leader. The world's first jet plane came from Germany in the Second World War, and the V2 rocket opened the door to modern rocket technology. It is because the German heavy industry contribution in baking, the Soviet Union in the jet engine starting from germany. At that time, Germany was defeated, and the enemy's material became the focus of the Allied forces, but the Soviet Union was preoccupied with seizing industrial goods such as machine tools and forgetting to attract those technicians. As a result, the technical experts who were regarded as "air" by the Soviet Union were all attracted by the United states. Since the Soviet Union thought to get equipment and equipment available, the successful development of the new engine is not a problem, only to find later, not just blindly imitate bad trouble, but due to the lack of professional and experienced technical personnel, development schedule of the Soviets themselves significantly delayed, the initial stage is behind the west.

其实,俄罗斯上至苏联就是发动机一直造不好。那到底是什么原因让俄罗斯的航空发动机长期受限呢?我们中国可以从中学到哪些什么?

众所周知,德国以重工业立于欧洲。在重工业的各个方面,德国都是领跑世界的。世界上第一架喷气式飞机就是出自二战德国,V2火箭更是开启现代火箭技术的大门,直至今日,人类所以用的火箭技术都源于此。正是由于德国在重工业发面的建树,使得苏联在喷气式发动机的起步都源于德国。当时德国战败,敌人留下的物资成了盟军抢夺的重点,但是苏联只顾着抢夺像机床这样的工业实物,忘记了将那些技术人员招揽走。结果那些被苏联当成“空气”的技术专家都被美国招揽了。苏联自以为拿到现成的设备和装备,研制成功新的发动机不成问题,到后来才发现,不仅仅盲目仿制坏了事,而且由于缺乏专业的、有经验的技术人员,苏联人自己的研制进度大幅拖延,起步阶段就落后于西方。

This is something we once imagined in china. At that time, we had the Soviet jet engine, as it has just begun, the first thing to solve is whether there is something or not, so our policy is imitation. At first, the speed of imitation was certainly faster than the speed of development, and we tasted the sweetness. At that time, we neglected the establishment of a complete aviation industry system in china. Materials science, various types of assembly, processing and process technology have not been paid attention to and development, and later, we encountered an embarrassing situation is that imitation speed is not up to the speed of creation. We have introduced the British "Spey" engine, made in the production license, we took off the engine as a sample copy, made out of the various performance indicators and imported from England to the poor on a big cut. The core technology of the engine is material and processing.这一点与曾经我们中国很是想象。当时我们已经苏联的喷气式发动机,因为刚刚开始,首先要解决的是有还是没有的事情,所以我们的方针就是仿制。一开始仿制的速度当然要快于研制的速度,我们尝到了甜头,当时忽略就在当时建立起中国自己完整的航空工业体系。材料学、各个工种的装配、加工以及工艺技术都未得到重视和发展,到后来我们遭遇的尴尬局面是,仿的速度赶不上造的速度。我们曾经引进英国的“斯贝”发动机,在取得生产授权后,我们拿着现成的发动机做样品照抄,造出来的与从英国进口来的各项性能指标都差上一大截。发动机最核心的技术就是材料与加工。

Weak industrial base is also one of the reasons. China and the then Soviet Union had such problems, and the innovation also played a vital role in the improvement of the engine. No matter which country, the engine development is the same strain. With the beginning of the core machine, it will gradually develop towards the second and third generations. Due to the weak industrial base, lack of innovation, led to the Soviet Union of aero engine research way is often such as process level does not pass, the level of resistance to high temperature low metal material problems, resulting in products is limited, low yield and short service life and poor safety.工业基础薄弱也是原因之一。中国与当时的苏联都存在这样的问题,并且创新在发动机的改进上也发挥着至关重要的作用。无论是哪个国家,发动机的发展都是一脉相承的。有了最开始的核心机,就逐渐向着第二代、第三代发展。而由于工业基础薄弱、创新能力不足,导致苏联航空发动机的研发途中常常会受到诸如工艺水平不过关、耐高温金属材料水平低等的困扰,最终导致产品受限,既产量低,而且寿命短、安全性差。

The F-135 engine is equipped on the US F-35
So we should learn from the first, is to set up their own complete system of the development of the aviation industry, the aviation disciplines should to reject nothing, refinement, some parts, sub system should be clearly defined; to encourage innovation, attract innovative talents, the country's soft power can not be ignored; pay attention to the basic process of inquiry. The core technology is not in the hands of many engineers on the drawings, but in the hands of the hands of the technical staff, training of qualified workers experienced the same is king.

所以我们要从中吸取的,就是要首先建立起自己的完整的航空工业发展体系,细大不捐,各个航空学科都要细化,一些零部件、子系统都要有清晰的界定;大力鼓励创新,吸纳创新人才,国家的软实力不容忽视;重视基础工艺的探究,很多的核心技术是不掌握在工程师的图纸上的,而是掌握在技术员工的一双手上,培养有丰富经验的合格工人同样是王道。
