"Oh, hehe, let's talk about it? What the hell is going on with this business you want to do. ”

Liang Liang asked with a smile!

"Hehe, it's the Russian an-F, or the an-fn, it's okay!"

Li Zhiyang said with a casual smile.

"Oh, hehe, yes!"

Liang Liang smiled, as if he said casually!

But Li Zhiyang saw that when this guy heard the motive model he reported, the glint in his eyes flashed!

It seems that this guy is still moving! Li Zhiyang secretly pondered in his heart!

In fact, I can't help it, this Liang Liang and that Du Yu are not moved, after all, these two motives can be said to have a wide origin with the Celestial Empire!

These an-F or an-FN motives are not only widely used in Russian fighter jets, but also in the current mainstream fighters of the Celestial Empire, which are also widely used!

In fact, these two motives, but in recent years, the Celestial Empire has been trying to imitate, copycat motives!

These two motives, since their birth, can be described as classics!

This AN-F motive was studied as early as 976 in the former Soviet Union, and it took a total of 9 years, known in 985 years, to be successfully developed, and then widely used in Su-7, Su-O, and Su-5 fighters!

Even in the new century, fighters using this motive are still not lagging behind other fighters that are not enough for other countries in the world!

At present, the mainstream fighters being used by the Celestial Empire, Su-7, Su-O, and the imitation J-1, as well as the J-O fighter currently independently developed, are all used with these two motives!

The motivation of the AN-F model is mainly used in the type, or the heavy punishment of the twin fighters "such as the Su-27, Su-O, or the J-1!

As for the improved version of the AN-F, the AN-FN is mainly used in single fighters, such as the J-O!

Therefore, these two motives can be said to be absolutely not unfamiliar to the Air Force of the Celestial Empire!

And according to the current international and domestic situation, these two motives will be "still in service with the fighters of the Celestial Empire" for a long time!

Although in the J-o fighter, after the birth of the Celestial Empire, the Celestial Empire military has already sent a message saying that it can produce a single fighter motive that is not weaker than the An-FN, S-OA, that is, the Tai mobile aircraft that is rumored on the Internet!

However, the performance of the specific Tai mobile machine has always been in the world, causing suspicion among military enthusiasts, "After all, the smelting technology level of the Celestial Empire, and material science in the world, are really suspicious and listed as unpopular!"

During Li Zhiyang's stay in Russia, especially after reaching a series of secret agreements with President Puting, he also worked hard and spent a period of time "to study the data of Russia's two motives, as well as the motives of the Celestial Empire!"

So now he has come to negotiate with these two, although he can't become an expert, but at least he can be called the level of half a bucket of water!

At present, there are many fighter jets that are also in use, but according to the current domestic production level, in fact, we can also produce them ourselves, so this deal is not easy to do!"

Du Yu, who had not spoken much, said to Li Zhiyang at this time, when he spoke, his face did not change" Li Zhiyang was very tender and judged from his expression whether what he said was true or false!

"Oh, huh, yes? But I've heard that our smelting technology doesn't seem to be very good?"

Li Zhiyang replied with a smile, this sentence is to the point.

In fact, the main requirements for the motivation of the fighter are size, thrust-to-weight ratio, life, stability, and whether the logistics maintenance is simple and so on!

The reason why the two motives of AN-F/N, which are now canonized as classics and have been used for more than 20 years, are still not lagging behind several newly developed fighters in Europe and the United States is because these two motives have reached a perfect balance in the above data!

The Celestial Empire itself has the ability to study fighter motives, and Li Zhiyang has no doubts about this at all, especially in the design and layout of the motives!

However, the shortcoming of the Celestial Empire's fighter engine research is our material science and smelting technology!

The reason why Russia's motives for the two an-series are powerful is because of the materials he uses on these two motives!

As soon as Liang Liang and Du Yu heard Li Zhiyang say this, they stopped talking, and they didn't know if Li Zhiyang said the sore spots, or if there were any restrictions on the confidentiality agreement, so the two of them didn't speak!

Li Zhiyang saw the two of them, and they were silent, and then continued.

"Actually, I also know that when we were researching the J-O, we have been imitating the single engine of the An-F model, and I know that we have successfully developed the model motive of the S-OA, and in terms of thrust, it is even higher than the thrust of the An-FN by 5oo kN, but everyone understands that the S-OA can only stay in small-scale production now, as for why it can't be used on a large scale, I don't think I need to say more!?"

Li Zhiyang's question was very sharp, and it can be said that anyone in the DPRK military today is very uncomfortable listening to it!

After all, this is the core of the problem, that is, the material science of the Celestial Empire is not up to par!

The two motives of angF/n, in the materials used, the Russians have really worked hard, they have made these two motives, both ends of the bits, are made of high-temperature stainless steel, in the core part of the turbine between the motives, and the combustion chamber, is the use of titanium alloy!

The most important thing is the use of these ferroalloys, which can be said to be the hardest in the world, but the material is the lightest, and at the same time, the performance of high temperature resistance is the best metal material!

And the price is not cheap, that is, Lao Maozi, the country with the richest iron reserves in the world, can use such a material with such a large amount of money!

In terms of the use of materials, especially in the use of ferroalloys, Li Zhiyang knows that it must be a big headache, because it involves material science and smelting technology, but it is precisely our shortcoming!

So although I don't know what materials our material scientists used to replace the titanium alloy used in the series of motives, this is also the reason why the stability and life of the Tai mobile machine we produce are much lower than the standard of ten years of use of the AN series!

This is also one of the reasons why there has been no large-scale production of the J-F after it was produced and designed! Because if it were the motive for purchasing a large number of AN-F models from Russia, a single unit would cost three million US dollars, and this cost would be a bit too high for the Air Force of the Celestial Empire!

After Li Zhiyang said what he said just now, none of the people present refuted Li Zhiyang, because what he said was indeed the truth!

The Ranmen Celestial Empire is not without talents, but lacks a system to retain talents, and the current Jinghua University and Imperial Capital University, the two most famous universities in the Celestial Empire, have basically become the cradle of the party's sticks!

In state-owned units, there are basically some people who are in the key positions of corpse vegetarian food, and these people are not engaged in scientific research at all, they are fighting for power and profit, and engaging in unspoken rules, as well as asking for scientific research funds like above!

And in their real positions, they have suppressed newcomers and slaved newcomers, either they are misappropriating other people's research results, or they have a set of plagiarism theories, and everything else is simply useless!

You don't see those so-called academicians of the Chinese Academy of Social Sciences, who have been frequently exposed on the Internet recently, plagiarism, misappropriation of funds, and fraud scandals!

In society, many private enterprises, because of the impetuous social atmosphere, there are not many private bosses who are willing to settle down, UA energy, UA time, and invest in those real scientific research projects!

This is an important reason why the economic transformation of the Celestial Empire is difficult, and large and small enterprises do not have real core scientific and technological competitiveness when they compete with international enterprises!

Liang Liang and Du Yu, plus Liu Tiejun, were a little silent for a while, and they didn't make a sound, they knew that what Li Zhiyang said was reality!

But even so, you must know that we are not very optimistic about the introduction of these two motives! You must know that these two motives, after all, are the products of the last century, and from the moment they were born, they are not superior to the FIoo-p-99 used by the Americans on the F5/6, they have the thrust and life! What's more, now the Americans are using the F's motive is the F9, which is a new generation of turbofan motive, not a turbojet motive, and his thrust-to-weight ratio is already over 1 to 10!"

Du Yu broke the silence and said to Li Zhiyang, although he didn't say it explicitly, he had already told Li Zhiyang inside and out of his words that the motives of these AN series are already backward!

The air force of the Celestial Empire, although it is not the best air force in the world, has the determination to become the best air force, so in the motive of the fighter, the motive of these AN series is indeed out of the eyes of the military of the Celestial Empire!

"Hehe, it's Brother Xiao Li, you know, the motives of these Russians, compared with the motives of the Americans, are actually inferior in terms of thrust-to-weight ratio, fuel consumption, eyebrow life, and maintenance!"
