Chapter 1158: Huashan

Was Tan Zhenhua really fooled? In the spring of 1987, no one except him probably knew the answer, but one day after a year, everyone’s reaction was like this
While Wang Xugong smiled uncontrollably, he slapped the table and panted and shouted into the microphone: "Say, Tan boy, did you think that there would be today?!"
Lin Hu put down the briefing in his hand, stood up and paced to the window, looking at the new shoots from the branches outside the window, but a smile appeared at the corner of his mouth, seemingly relieved, but also self-deprecating, and muttered: "This cunning little fox!"
Chen Yijian shut himself in the house, and took him and Tan Zhenhua carefully after realizing all the past. After thinking and thinking, the doubts in his heart became more and more. This Tan Zhenhua, can it be from knowing himself? Have you been planning today’s scene since that day? How is this possible? How did he know?
Of course, Tan Zhenhua's answer is unanimous, firm, and categorical: "All this is just a coincidence!"
...
Now that I have come to Xijing, Xihangfa must go shopping. This is one of Tan Zhenhua’s most attention, and it is also the core of all his business cores. It is also the most profitable investment in the military industry. Strong business.
When he stepped into the gate of the West Air Development Factory, he saw the old man Wu Daguan who was hurriedly walking out of the door. The old man's expression was excited and urgent. He was overjoyed when he saw Tan Zhenhua and he stepped forward and grabbed him. He dragged his hand and walked out and said: "Zhenhua, you are here just right, go, come with me."
"Uh, Mr. Wu, where are you going in such a hurry?"
"Where to go? Of course, to the airport, walk around, hurry up, you won't be able to catch the flight anymore."
"Wu, wait a little longer, what's the problem if the flight is not a flight? I just received a notice that my private jet has been changed back and can return it to me at any time. I will show you to try it... …"
When Tan Zhenhua and Wu Daguan stepped into the gate of the 3624 Gas Turbine Institute in Jiangyou City, Xishu Province, they saw Liu Daxiang and his party who had been waiting here for a long time.
Wu Daguan couldn't care about his age and seniority at all. He took a step forward and shook Liu Daxiang's hand tightly, and asked excitedly: "Thinking about it, succeeded?"
Liu Daxiang's eyes were full of pride: "Old Wu, we are still the last step!"
"Go, take me to see!"
"it is good!"
The two turned around, arm in arm and headed straight for a towering factory building, completely aside Tan Zhenhua who had come with them.
Tan Zhenhua had no choice but to touch the back of his head with self-deprecation, and said in his heart: Is he transparent? Such a big living person, or a big gold master who has paid out countless real gold and silver, is so completely ignored.
But looking at the flying white hair of the old man who was walking like flying and the little stars on the head of the middle-aged man, there was a mixed feeling in his heart, with emotion, admiration, respect, and more. There is a heavy responsibility...
Walking into the tall factory building, a strong burning smell suddenly came over the surface, but the three seemed to be indifferent to it, their eyes focused on a huge cylindrical object placed on the middle shelf. .
It was lying there quietly, its huge body was covered by various dense and neat pipelines, exuding a faint metallic luster, and in Tan Zhenhua's eyes, it was clearly the light of modern technology!
This is an aero engine.
Tan Zhenhua knows that this is the afterburner version of the "Speey RB168-Mk807" engine jointly developed by Gas Turbine Institute and British Rolls-Royce Company, and it has a mighty new name in China-Huashan!
Huashan Mountain has been called "the most dangerous mountain in the world" since ancient times. Its peak is connected to the Qinling Mountains to the south and Huangwei to the north. It is the sacred mountain of the Chinese nation. The "Hua" of China originated from Mount Hua, which was called "the root of China" by Mr. Zhongshan.
And the aero engine that was born out of "Speey", which is also called "Qinling" by China, was nominated by Tan Zhenhua, and it was immediately recognized by everyone. The name "Huashan" not only reflects the importance of this engine The great significance of China Huaxia also points out its relationship with the "Qinling" series, and it deserves its name.
"This engine has a total length of 4230 mm, a maximum diameter of 1004 mm, a delivery mass of 1320 kg, a maximum military thrust of 5 tons, a maximum afterburner thrust of 8.25 tons, a thrust-to-weight ratio of 6.25, an afterburner ratio of 1.10-1.65, and a full life span of 1500 hours. , The first turn life is 500 hours, the turbine inlet temperature is 1155 degrees Celsius, the fuel consumption rate in the intermediate state is 0.676kg/(daN·h), the fuel consumption rate in the maximum afterburner state is 2.218kg/(daN·h)......
Liu Daxiang’s introduction came in his ears. He announced the parameters of this outstanding work that has condensed the efforts of all the gas turbine institutes, and the words revealed immense pride.
Of course he is qualified to be proud.
Although the "Huashan" engine was developed from the "Speey RB168-Mk807" engine, its original model was originally an afterburner engine. It should be known that the design of the aero engine is extremely complicated, and any parameter change is It may affect the whole body. Adding an afterburner to the basic model is by no means as simple as "welding" the last section of the combustion tube. It involves the adjustment and adaptation of almost all engine core parameters, which is difficult and complicated. It’s not much simpler than designing a brand new engine from scratch. In other words, if you want to do this job well, you must start with the initial design idea of ​​this engine and fully understand all its design elements and principles. may.
Here is a realistic example-in another time and space, at the beginning of the 21st century, Huaxia purchased the AI-222-25 engine from Wukelan for the new generation of trainers, but this model of engine was not added. In order to meet the actual needs of the third-generation trainer aircraft, China has requested the producer of this engine Uklan Zaporizh Ivchenko Progress Design Bureau and Motor Sic Power Company to develop the engine for this type of engine. An afterburner is added to the foundation, which can add an afterburner to such a relatively simple small thrust turbofan engine. Wukelan has been tossed for more than ten years without a complete porcelain.
Of course, there are many complicated factors that affect the progress of this project. The turbulent political situation in Uklan and the loss of a large number of professionals should be the biggest problem, but this also fully illustrates the complexity of major improvements to an aero engine. And difficulty.
In this time and space, according to Liu Daxiang’s original suggestion to Tan Zhenhua, this jointly developed "Huashan" engine project was mainly led by China, and most of the experiments were also carried out in China. He took over the project. To this day, four full years have passed, more than a thousand days and nights.
"Although the thrust-to-weight ratio of this engine is still far from the goal that we hope to exceed 7, but with the current performance, we think it can replace most of the turbojet engines currently in service in China. Now, we have accumulated more than 10,000. Hours of ground and high-altitude bench test time, approved by the state, the "Huashan" engine is about to officially undergo installation flight testing. The test aircraft will be modified by a "F-8". However, our country just promulgated the latest GJB241-87 and "General Specification for Aviation Turbojets and Turbofan Engines" this year. This new standard largely refers to the U.S. military standard, which is quite different from the Soviet-Russian military standard inherited by our country. It is different. Therefore, we still have a lot of work to do to pass the national acceptance. It is expected that through 2-3 years of hard work, our "Huashan" engine will truly enter a mature and usable state."
After saying this, Liu Daxiang finally realized something. He couldn't help but turned his face to Tan Zhenhua and smiled apologetically: "Oh, right, Mr. Tan, I just said it, I forgot to thank you for a while. Without you, our project It will never go so smoothly."
Tan Zhenhua curled his lips, yes, you finally remembered me.
