Supreme Golden Pupils - Chapter 564 The Russian Aircraft Engine Going Evil

"Radar and engine? Well, these are indeed two big problems, especially the engine, known as the crown of modern industry, involves a lot of technology and is very complicated, and it is imitated first when it lags far behind the world's advanced level. , After having accumulated a certain amount of technology, it is also a shortcut to innovate independently. Is there a specific imitation object?" Ling Shaonan asked after pondering for a while.

"For the time being, we still set our target on the Su-'fighter. This is a very good fighter, and there are many places worthy of our study. However, the Russians have never been good at electronic technology. The fire control radar and electronic equipment The level is not even as good as ours, we just need to learn from their ideas and some unique designs, but we are completely behind in terms of engines, and we need to carry out a comprehensive survey and imitation of the al31-f engine."

For some reason, the serious expression on Ling Shaonan's face made Ma Xingchu feel like he was reporting to the leader!This feeling is absurd, even he himself finds it unbelievable, but it makes his attitude more serious.

"Well, the Russian engine technology does have its own unique features. However, although I don't know much about these things, I have a suggestion that I hope the Air Force will consider." After a little consideration, Ling Shaonan said slowly.He knew the development process of China's military aero-engines in the next ten years, and also knew that there were many detours, so he couldn't help but want to mention Ma Xingchu.

"Oh? Boss Ling, please speak up."

"As far as I know, Russia's military aero-engines follow two paths from Europe and the United States, which is mainly due to the difference in combat purposes. From the former Soviet Union to the present Russia, the emphasis on air combat is the beginning 5 Minutes, I am stronger than you in these 5 minutes, and I can win. Of course, for the same 5 minutes, the European and American armies are guaranteed by three people for one hour, while Soviet Russia needs [-] people for ten hours. Because they don't have scientific management methods, what they pursue is winning battles, not cost performance.

Russia is also aware of its lack of finishing capabilities, so the performance of the aero engines they process cannot be compared with those of Europe and the United States. As a result, their air forces are very different from those of Europe and the United States in terms of combat theory and thinking. , Their strategic thinking is that you play your high technology, and I play mine high investment.

The most important indicator of the current aero-engine is the thrust-to-weight ratio, and there are two ways to increase the thrust-to-weight ratio, one is to increase the temperature and thrust, and the other is to reduce friction and reduce losses.European and American aero-engines produce high thrust-to-weight ratios by means of finishing, while Russian engines rely on thermal energy and cooling technology to adjust the gas temperature to the highest without burning out the engine. The purpose of competing with European and American aero engines with advanced precision manufacturing.

To put it simply, the Russians were playing the same set during World War II. During World War II, the German Nazi Tiger tank was simply a nightmare for the Allied forces. At that time, there was no tank in the world that could compete with it, but in the end it But it was abruptly submerged by the t-34 tank of the former Soviet Union, and it was wiped out.

The reason is very simple, that is, the manufacture of Tiger tanks is very troublesome, and many workpieces require very precise processing, but the T-34 of the former Soviet Union does not need this at all. They are very simple to manufacture, and they are not even described as shoddy. However, compared with the Tiger tank, the t-34 can be completely regarded as garbage in terms of craftsmanship and processing accuracy.

But it was such a shoddy tank that completely suppressed the Tiger, and even defeated the Germans for thousands of miles in the end, relying on their number.When the German tanks were still laying on the production line in strict accordance with the production process, and had to undergo various inspections after they were manufactured, the t-34s of the former Soviet Union had been continuously rolled off the tractor factory and were directly driven into the battlefield .

No matter how awesome a Tiger is, can it beat a hundred T-34s?

As far as the current aero-engine field is concerned, although this description is somewhat inappropriate, the general concept is similar.

It is precisely because of this design concept that the level of Russian aero engines is indeed much worse than that of Europe and the United States.For example, in high-speed air combat, it is necessary to keep the aero engine running at the maximum power output mode. American aircraft can last for three to ten minutes, or even an hour.However, Russian fighter jets can only last for 10 minutes.

In this way, the Russians began to think about how to ensure that their fighter jets could suppress the American fighter jets within 5 minutes, so they began to work hard on increasing the temperature of the combustion chamber and increasing the thrust.This is different from the Americans who rely on precision machining to make a fuss.

Which of these two paths is better or worse is self-evident.

It is true that in the initial period of the war, the Russian fighter may maintain a certain advantage, but as soon as this period of time passes, he is finished.And in terms of cost performance, Russian fighter jets are indeed inferior to Americans, because their fighter combat modes require more fuel, which consumes more energy, and the combat radius is not as far as that of the Americans.Therefore, except for the Su-', which uses a large fuselage and a high fuel coefficient to ensure a fuel load of more than ten tons, other Russian fighters basically have short legs.

More importantly, if the fighter jet is in this mode for a long time, the life of the engine will be greatly shortened. This is why American fighter jets can be used for 30 to [-] years if they are properly maintained, and the engine life is as high as three to four thousand hours. It is difficult for the engine life to exceed a thousand hours, and the main reason why fighter jets are finished after a few years of use.

In addition, as far as the current world development trend is concerned, it is not cost-effective to develop a purely military engine. The production of aero-engines should also consider the issue of civilian use. After all, the civilian market is much larger than military use.Among other things, after 20 years of development in China, the aviation industry has also made great progress. In the next ten or 20 years, the demand for large and medium-sized civil airliners may be as high as several thousand, with a market size of hundreds of billions of dollars. Are we willing to give up the big market to European and American companies?

The Russian aero engine model is not suitable for civilian use at all, but the American one is very suitable. Take the cfm-737 engine used on the American Boeing 56 as an example. It was originally developed for military fighter jets, but it was later developed with the f-100 It failed in the competition, so the f-100 became the military engine of the f-16, and this cfm-56 became the special engine for the famous boeing 737.

However, there are basically no such examples of Russian engines, because they are too fuel-intensive, and their lifespan and post-maintenance are very problematic, and airlines simply cannot afford their high costs.Therefore, I think that the Russian aero-engine technology is just a trick, and the Americans are the kingly way.

So, from this point of view, I have no objection to imitating the al31-f engine, but in the process, we must take the essence and discard the dross, absorb it creatively, turn useful technologies into our own things, and develop something better than the al31 -f better engine to come!Only in this way can aero-engines change from the current short board to a booster for the development of our country's air force, and make the air force truly a strategic force that can fight and win if it is called! "

Hearing Ling Shaonan's discussion, Ma Xingchu and the several air force officers he brought were stunned, their eyes widened, and their faces were incredible: Nima!Is this what you mean by "not understanding"?It is hard to understand the advantages and disadvantages of the two aero-engines of the United States and Russia so thoroughly. Aren't we all idiots? !Although they are not professional technicians, they can also hear the importance of Ling Shaonan's remarks, which can be regarded as a guiding principle for the development of aero-engines!

After a long time, Ma Xingchu, whose eyes were twitching, came back to his senses, took a deep breath, and said with a trace of respect that he didn't even notice: "Mr. Ling, I will definitely tell the truth when I go back. Report to the chief and communicate with relevant departments, do you think there is anything else that needs to be added?"

"This is just my family's opinion. General Ma is too polite. In this way, I will invest 30 billion yuan a year to support my country's aero-engine technology research. I hope the country can make up for this shortcoming as soon as possible. As for the 30 billion yuan? Whether it is spent on design, processing and manufacturing, or various experiments in the later stage, I, a layman, will not talk too much.

In addition, our country is indeed relatively difficult at present, so in addition to the development of new models, we need to work harder on the potential of existing models, but like the "Peace Model" that we cooperated with the Americans ten years ago Don't make any more improvements, we were tricked by the Americans.

The J-8 is known for its high-altitude and high-speed. From the aerodynamic layout to various configurations, it is aimed at high-altitude interception. If it is to be improved, it must continue to go in this direction. It is simply natural to turn it into a multi-purpose or fighting fighter. Useless martial arts!For air combat we have J-7 and Su-', for ground attack we have Qiang-5 and Flying Leopard, and we signed an agreement last year to introduce Su-30. Compared with them, J-8 has no advantage at all, and its positioning is also It will be very embarrassing, and in the end there will be no second result other than being forced to retire early.I don't think the Air Force wants to see that kind of situation either?

Finally, I hope you will pay attention to the fact that Russian engines are not so easy to imitate, and those old men are also uneasy. They sell us the reduced version, which is the so-called monkey version. When we imitate, we must Be careful not to be accidentally led into a ditch by the Russians. "
