General Staff Intelligence Department Data Center.

After 5000 million U.S. dollars was deposited into the Swiss bank account, Peng Guochen has been waiting for news in the data center. Although the smooth progress of this transaction was made after a meeting of the Supreme Council of Elders, it is not that no one has raised objections. Naturally, Peng Guochen was under a lot of pressure.

"Minister, all data files are automatically unlocked and can be read!"

Peng Guochen lifted his spirits, and said: "Immediately back up these materials, and hand over the printed documents to the Archives Bureau for safekeeping, and provide them to relevant experts for analysis and interpretation. The confidentiality level is top secret!"

"Yes!"

"Wait a minute! One more thing, didn't he advertise last time that he could sell anything? You can ask him on TT if he can help us get the Russian 117s aero engine."

This was just Peng Guochen's impromptu idea, a response to Zhan Huju's molesting advertisement last time. He didn't think Zhan Huju could really get the real 117s aero-engine.

After all, so far, what the Bureau of War and Ignorance has demonstrated is its amazing intelligence gathering capabilities, hacking capabilities, and terrorist attack capabilities.

However, as more and more details about the Tokyo terrorist attack came together, the high-level officials were very vigilant about this organization.

During this period of time, all Huaxia's intelligence networks at home and abroad, whether it was the National Security Bureau or the General Staff, were running crazily, trying their best to find traces of the Bureau of War and Negligence, but so far there has been no progress.

The Bureau of War and Sudden Appearance is like a ghost, appearing very strangely. The only consolation is that this organization has not shown any hostility towards China, but no one can guarantee whether they will do something like Tokyo in China. Big things are coming.

There is also a reason why Peng Guochen asked Chen Xin if he could help him get the 117s aero engine.

When the Russian Defense Minister visited China in September last year, high-level military officials intended to purchase a batch of 117s aircraft engines and S-400 air defense missile systems.

However, the protection of intellectual property rights in the field of military technical cooperation between China and Russia has always been a big problem. Russia imitated the Su-27 (domestic model is J-11, and its derivative and improved version is J-11b) fighter jets and s300 series air defense missiles (domestic model) to China. Therefore, when the Chinese side proposed to purchase 9s engines, the Russian side’s response was not very enthusiastic.

It's just that Russian military enterprises still have great interest in exporting high-tech military equipment to China out of practical interests.

But really wanting to get the 117s aero engine requires long negotiations and waiting. With the first flight of the J-20 fighter jet, the military's demand for high-performance aero engines has once again become eager, which is why Peng Guochen asked this question.

tt made a beeping sound, Chen Xin opened it, and his eyes lit up immediately.

117s engine, the military really dare to do business with him?

Chen Xin quickly typed: "Yes, how much?"

Peng Guochen frowned, Zhan Suju's tone was still the same as before.

Peng Guochen said, "How much can you get?"

Chen Xin turned his head and asked Gangbun: "Gangbang, how many units do you think is suitable for reporting?"

Gangzhu's eyes glowed, and he said, "Have as much as you want, the more the better, it's all money!"

Chen Xin was already speechless to this guy who got into the eyes of money. After thinking about it, he felt that it was his first arms business and he couldn't report too much, so he replied: "About ten units!"

TT from the Intelligence Department of the General Staff fell silent, and after a few minutes, there was another reply: "Can you really get 117s?"

Chen Xin curled his lips in disdain, and wrote: "Nonsense! We can get even f119-pw-100!"

The 117s engine is just an in-depth modification of the al-31f engine (equipped with Chinese J-10, J-11 and other fighters). It uses a vector nozzle with a maximum thrust of 14.5 tons. When the afterburner is not turned on, the thrust reaches 8.8 tons, and the life cycle reaches 4000 hours. Twice the original model al-31fp.It is mainly used to equip Su-35 and T50 fighter jets. For now, the 117s engine is actually a third-generation improved power similar to the al-31f-m2 engine, but its performance is not enough to be called a transitional model of the fourth-generation power.

In contrast, F119 is an afterburning turbofan engine with a thrust-to-weight ratio of 22 developed by Pratt & Whitney for the F-10 "Raptor" fighter jet. The structure and performance represent the level of the most advanced fighter engine at present. The maximum afterburner thrust is 17.5 tons. Without the afterburner, the thrust reaches 11.4 tons, which is much higher than the level of 117s. .

Peng Guochen took a deep breath and asked, "How much is the unit price of f119?"

Chen Xin wrote: "Two million dollars!"

Peng Guochen said, "What about 117s?"

Chen Xindao: "800 million dollars!"

Peng Guochen felt speechless, this is really the price of conscience!

You must know that over the years, the research and development cost of f119 has reached 24.56 billion U.S. dollars. Even if the Yankees have equipped 187 f22s, each aircraft is equipped with two f119s, and some more are produced for backup, and the purchase quantity is only four About 1000 units, plus material costs and labor costs, the cost is more than [-] million U.S. dollars.

Even for the 117s, the price quoted by Russia to the Chinese side has reached 1000 million U.S. dollars.

Peng Guochen no longer considered whether this matter was true or false, and it was better to report it to the higher authorities for a decision. If the other party can really get these engines, then the importance of their negligence may be raised to a higher level.

Peng Guochen said: "Well, I will report to the higher authorities in time, and I will give you an answer then!"

Chen Xindao: "OK, ten F119s plus ten 117s turbofan engines, cash on delivery, I will notify you when the time comes!"

After getting off TT, Chen Xin turned his head and asked Gangjun: "Gangjun, help me find out, which countries will hold large-scale airshows recently?"

Without raising the head of the steel pen, he said, "From June 6th to June 20th, the Paris Air Show!"

Chen Xin is overjoyed. The Paris Air Show is one of the largest air shows in the world. F22 and Su-35 will definitely participate in the exhibition, and the F119 and 117s turbofan engines will be available.

As a military fan, Chen Xin has a long history of resentment towards China's military aircraft engines, and now that he can do his part in this area, he will naturally not be stingy.

In fact, the engine has always been China's weakness.

It has been more than 50 years since Premier Zhou Enlai commented on the "heart disease" of Huaxia Aircraft when he was alive.Huaxia's engine is still the biggest weakness of the weapons industry.

Not only turbofan engines for fighter jets and large transport aircraft, but also turboshaft engines for helicopters, turboprop engines for medium transport aircraft, gas turbines for large ships, diesel engines for small and medium ships and tanks... without exception, all It is China's weakness.

The aero engine is even more the weakness of the weakness.

So far, in the field of aero engines, the gap between China and the United States is at least 30 years, a generation to a generation and a half. We cannot deny this fact.

There are many reasons for this. The first is the problem of industrial foundation. When Huaxia was founded, the industrial foundation was too poor. Not to mention aero engines, there was not even decent tool steel.

If it hadn’t been for the Korean War, Huaxia used the priceless blood of a large number of young soldiers to consume cheap steel from the United States, and in exchange for the Soviets to give us the manufacturing technology of turbojet engines, it would be impossible for Huaxia to produce turbojet-1957 engines in 5 .

But compared to other fields, the foundation is also poor, and there are also humming setbacks. Why can't aero engines keep up?

For example, China is now the world's largest producer of white goods, and our smartphones, radars, rockets, and spaceships are slowly catching up.

Our first petascale supercomputer "Tianhe-11" also officially topped the top 500 list of supercomputers in November last year.

Even in the weakest chip field, we have also made progress. Hua has launched high-performance mobile high-end device terminal chips for its Haisi Semiconductor, which already has the ability to compete with international first-line manufacturers, and it is very likely to grow into A giant in the Chinese chip field.

The fourth-generation electromechanical avionics system exposed at the LY Optoelectronics Exhibition is no less than the American F35, and the Americans were surprised when they saw it.

China's air-to-air missile experts said leisurely that we are only about 10 years away from the Americans.

The US[***] side also believes that Huaxia Air Police 2000 is one generation more advanced in terms of technical system than the mechanical scanning radar of the e-3 "Watchtower" early warning aircraft equipped by the US military because it uses electronic scanning phased array radar.

In fact, in many weapons fields, the gap between China and the United States is only about ten years. What does this mean? It means that there is no generational difference.

But the aero engine is different from others, because it involves too much.

当年苏联人先后给了华夏涡喷－5（用于歼5）和涡喷－6（用于歼6）、涡喷7（用于歼7）的图纸、技术工艺资料和样机，但是有两样东西我们没有得到。

One is the design principle, that is, why does this engine do this, what is its design principle, and what is its fluid dynamics model?

The other is the design experiment data. Why is this material used for this elbow? Can other material formulas work?Bend 75 degrees, extend 8cm, then bend 74 degrees, okay?Can it be extended by 7.9cm?What are the consequences of positive and negative deviations, why is this design optimal, and what is the safety margin in the optimal design?

Without these things, the Chinese made a turbojet 5/6 in the factory.

Based on this, some people commented that in the 50s, the gap between China and Americans was only half a generation to one generation. Why is the gap widening now?

joke!

Being able to manufacture it does not mean that you can design such an engine. Your manufacturing ability may be half a generation behind others.But how bad is your design ability?I don't know, because you are zero and cannot be compared.

Without design ability, let alone designing a new engine, you still don’t know how to modify an existing engine.

Huaxia originally imitated so many aero engines. If they want to improve performance, most of them can only rely on safety strength reserve and life reserve, at the cost of sacrificing reliability and safety.

In foreign countries, under the condition that the entire structure of the existing engine remains unchanged, only some small local improvements can make the performance of the engine greatly improved, and it will increase to 5% of the prototype in 10-120 years. Quite normal, and does not affect longevity and strength.

Without design ability, let alone change, even if you use your existing ability, you don't know how to start.

Huaxia's J-6 engine turbojet 6 has a full lifespan of only 100 hours, and is ridiculed by the Americans as a "disposable engine" (the Americans in the same period were 1000-1500 hours). The same turbojet 6, the Americans got it, analyzed it, and re- Assembled, life is doubled!

This is only a problem in the field of design, and there are more problems involved in fields such as materials, processes, and experiments.

In the past, there was an anecdote in the military world. A certain research institute managed to solve the material problem of the powder alloy turbine disk. When it was ready for cutting, it found that the tool hardness and toughness of the machine tool were not enough. What should I do?Start from scratch!

All in all, aero engines are a big test of the industrial foundation of the entire country.

Not to mention China, but Germany and Japan, the engines before World War II were so good.After World War II, the Americans restricted it, and now their car engines are so good, but their aero engines are not good. Why, because they lack links, they are no longer complete.

Therefore, in order to save trouble, the Germans simply bought airplanes instead of building them.

In Japan, I build airplanes, but I buy engines from the United States.Even for a small number of self-made aero engines, there are still a lot of production technologies and production licenses that are purchased (more importantly, like Chinese imitations, they lack complete design principles and data).

Japan's material science is very developed, and some individual basic researches are leading in the world. The fifth-generation single crystal alloy in Japan has come out, but is there a self-developed aero-engine model that is equipped in batches?It's not like being a working girl for Luo-Luo.

As for India, if you are engaged in the IT industry, you can buy semi-finished products internationally, outsource or subcontract.

But as far as the industrial base is concerned, it is not even qualified for the mass production of rifle bullets.

You let him try the aero engine industry. The Kavli turbofan engine, which was developed in 1986, has been a class teacher for 26 years. The maximum thrust is 7137 kg, the thrust-to-weight ratio is 6, and it has accumulated more than 60 hours of flight tests in Russia.Finally, at the Indian Defense Exhibition in April 2012, Minister of Defense Anthony announced that the research and development work would be stopped because the technical indicators could not be met.As far as this indicator level is concerned, it is not even as good as China's turbojet 4b in 2003.

Therefore, the aero engine must be improved,

Ask for money first.A lot of money, how much?A country's modern industrial base is as much as it needs.Can't save.Where there is a province, there must be a short board.The development cost of one engine model in the United States reaches 15-30 billion US dollars, and the engine is piled up with money.

The second is time.What is it for?Accumulation, continuous accumulation and precipitation of technical theory and engineering practice experience.Only by being able to make it can we talk about mass production and cost reduction.Make up the lessons that should be made up, theoretical pre-research, core mechanism production... If you haven't done these, you don't know what's going on.Sometimes there are no shortcuts.

The third is to have a chance.what chance?own model.To go through the complete model process, and to use it on the plane, to use it on a large scale, no matter how expensive it is, no matter what kind of problems you have at the beginning, you must try to use it, change it, use the model as a platform, and realize the technical theory , Continuous optimization of material technology and production technology.

ps: There are a lot of things to say about aero-engine steel, so don’t complain about steel materials, a lot of content in this chapter is excerpted from a post written by a netizen “Weapon Fan’s Sky”—中[*** ]Analysis with aero-engine, if you are interested, you can go and have a look.
