Chapter 768: Two one adds five

"Teacher Song, I've heard a rumor. A few years ago, we got a lot of good things from a friendly Arab country?" He cautiously probed.
The history of China’s acquisition of "MiG 21MF" and "MiG 23", which was talked about on the Internet in his previous life, must have not been decrypted at this moment. He dare not say it casually, it will give Both myself and these people here are causing trouble.
Song Wenhua glanced at him and said, "You have very long ears." After a pause, he sighed slightly and said, "I'm afraid that the distance will not quench the near thirst."
By saying this, he undoubtedly admitted indirectly that there is indeed such an engine under development, and Tan Zhenhua knows that the engine under development is in his previous history, throughout the 1980s, 1990s, and even the early 21st century, China Airlines The most important power core-the "turbojet 13" engine, it is this engine equipped with the later "J-7" and "J-8 II" fighters, supporting most of China's sky!
"Turbojet 13", Huaxia used the experience gained from the imitation and improvement of the "Turbojet 7" engine, combined with the research on the original Soviet Russian P-13-300 engine equipped on the "MiG 21MF" obtained, A medium thrust turbojet engine successfully developed.
This engine is composed of an 8-stage axial compressor, an annular combustion chamber, a two-stage turbine, an afterburner, etc. It uses an air-cooled I-stage crowned blade, and the compressor stage is equipped with an anti-surge device, which greatly Improve the power and reliability of the engine; due to the substantial improvement in the structure of the compressor, the surge margin of the engine is significantly improved. After the low-pressure rotor is added with the inter-shaft bearing, the vibration is reduced, and the compressor rotor disc and A large amount of titanium alloy is used in the blade, which not only reduces the weight but also improves the working strength of the blade.
Through the application of these new technologies, the thrust of the "Turbojet 13" reached 4.4 tons, the maximum afterburner thrust reached 6.6 tons, the thrust-to-weight ratio exceeded 6, and the aircraft's first turn life reached 300 hours, and its full life It was increased to 900 hours.
Compared with the world's leading turbofans, the "Turbojet 13" is obviously lagging behind, but for Huaxia, it is a big step forward. It marks that Huaxia's aviation development has finally moved from imitation and modification to self-design. An important shift in manufacturing.
The most important thing is that the development of this engine is steadily advancing. If Tan Zhenhua remembers correctly, it will fly to the sky next year and complete the development of the first model at the end of 1986, and it has passed China's national appraisal!
Calculating the time, combined with Ben Fang's three-year appointment with Song Wenhua, the time is actually just right.
Tan Zhenhua can search for this time from his own memory. Song Wenhua is not capable of him, and based on his consistent impression of domestic aviation, he said that "I am afraid that the long distance will not quench the near thirst" is understandable.
He had no choice but to comfort him: "Teacher Song, since there are already new developments under research, there is a possible solution, and your new aircraft research also takes time, and Mr. Ben’s radar also takes time. Since everyone is If you need time, then you might as well sit down and do it slowly, and always make sure that the things you hand out in the future are reliable and easy to use."
After thinking about it, he added: "Why don't we go back to London again and ask Sir Hook if they have a medium thrust engine based on Spey technology? If so, then we might as well buy it together— —Anyway, for Rolls-Royce, Spey is already considered an outdated product and there is no need to keep it secret for China, but for us, a turbofan that can be put into use immediately can fill the gap. "
Song Wenhua reluctantly nodded after pondering for a moment: "That's the only way."
"Since there is a solution to this difficulty, we might as well determine this future "Super J7"." Tan Zhenhua hit the railroad while it was hot: "I can use the purchased "Lavi" full set of technology to convert into shares..."
"Then take half of the shares and want the right to export all of this fighter jet? That's impossible!" Song Wenhua bluntly stopped the conversation and said: "Let's not say whether you buy the full set of "Lavi" technology to help this new fighter. How many, the current state of our "J7" is not the same as that of Lao Chen. The domestic equipment base number of thousands of aircraft, the results of two major technological transformations, and the accumulation of exports in more than a dozen countries can be It's not comparable to that unspecified "leopard", so you and Lao Chen's terms of cooperation should not be discussed with me, no way."
Well, Tan Zhenhua has to admit that Song Wenhua is definitely the most business-minded person of the older generation who has dealt with him.
He said with a bitter face: "Then, Teacher Song, tell me a charter and see how to cooperate? You can't let me just invest money for no good, right?"
Song Wenhua pondered for a while and said: "In fact, it is not necessary to buy "Lavi" only for the purpose of "Super Seven". The aerodynamic shape is too different, and there is not much reference value. Fly-by-wire control and bus technology can already be used from Dassault. I got it. Although there are many changes to be made from the dual-engine heavy-duty to the single-engine light-duty, it is still relatively easy to tackle. Others such as the screen display and the instrumentation. To be honest, I don’t see the British stuff more advanced than IAI’s. some……"
"So I don't need to spend this billion dollars, right?" Tan Zhenhua asked hopefully.
"Flowers still need to be spent, because they have some useful things, and I'm afraid they won't sell them alone... But I just thought about it, in fact, we can do this... Forget it, it's too troublesome to say one by one," Song Wenhua said: "Or, Zhenhua, give me the money and I will spend it."
"Uh..." Tan Zhenhua was choked out of speech.
Song Wenhua paid no attention to the change in the expression on Tan Zhenhua’s face, and continued to mutter to himself: "Ha, this is a good way, why didn’t I think of it just now? Let me do the math, one hundred million dollars can be... It would be great if we could have another 100 million..."
Tan Zhenhua was stunned as he watched Song Wenhua shook his fingers and figured out how to spend money. The scenes in front of him were all green bills escaping from his small wallet.
"Teacher Song, Teacher Song, the money is mine..." Tan Zhenhua said aggrievedly, his voice as small as a mosquito grunt.
Song Wenhua didn't seem to hear this at all. Well, maybe he didn't understand the meaning of the words. He was still thinking about it, and finally patted the table lightly and said, "Yes, it's done this way."
He turned his face and asked Tan Zhenhua: "Well, give me the one hundred million, and I will ask the old horse for another one hundred million. Our three families will add five to two. With these two funds, this "Super Seven" It's almost there."
"... Teacher Song, are you serious?"
