Rebirth of the Military Industrial Overlord

Shi Changxu looked at Tan Zhenhua with a smile on his face, and repeated softly: "Yes, it's the "Luo Luo" who built the engine. Why didn't you hear Zhenhua clearly?"

Tan Zhenhua hurriedly shook his head and said, "No, elder teacher, I heard it clearly. I was surprised because I heard it clearly. Of course I know the background of the "Luo Luo" company. I am just surprised. They are a company that builds engines and they want to buy one. What is the "carbon fiber" technology used for?"

"This, of course, has something to do with their ambitions, but it is precisely because of this technology, or their ambitions, that Luo Luo has fallen into an unprecedented pit." Shi Changxu uses a strategy. Replied with a joking tone.

His answer choked Tan Zhenhua, and said in his heart, judging from the tone of the old man's speech, he was probably not a peaceful master when he was young.

However, since the old man is talking about being positive, of course he has to do a good job of admiration, and then consciously said: "How big is this unprecedented pit?"

"How old is it? Hehe, so big that Rolls-Royce almost went bankrupt - not right, it should be said that it was already bankrupt. In the end it was the British government's assistance that barely survived."

The "Luo-Luo" company went bankrupt and was divided into two companies. Tan Zhenhua knew about it, and he also knew the fate of the two companies later. However, the "Luo-Luo" company went bankrupt. Carbon fiber, he heard about it for the first time.

So he asked, "Master, don't betray you, just talk about the reason, I'm so curious."

"This matter, of course, has to start with a huge aero engine order contract." Shi Changxu opened the conversation again.

"In the mid-to-late 1960s, the technology of large jet airliners was mature. Both American Airlines and Eastern Airlines proposed plans to purchase a large number of intercontinental airliners. At that time, it was American airlines that participated in the aircraft bidding plan. The two traditional large aircraft manufacturers: "Lockheed" and the newly merged "Mike Douglas", they launched the "Samsung L-1011" and "DC-10" respectively; and invariably adopted three The layout of the engine."

"Because there are hundreds of possible aircraft orders, the three major aero engine manufacturers in the West, Pratt & Whitney, General Motors, and of course, Luo-Roo have engaged in fierce competition for this. In the competition, these three companies reported higher and higher engine parameters, higher thrust, and lower prices. When Luo-Luo finally won the bid for the “Samsung L-1011” aircraft engine, its The project thrust has reached 181KN!"

"In order to achieve the design target, Rolls-Royce has adopted a series of new technologies, of which three should be the most important: First, the adoption of a large bypass ratio; second, the use of a new three-rotor engine system, and this The third is to use CFRP code-named "Haifeier", which is carbon fiber fan blades."

"I don’t quite understand the first two items. If you are interested in Zhenhua, you can consult Wu Daguan, but this last one, as far as I know, even if it is developed like Britain, it is very important to realize it in the late 1960s. One thing is difficult."

"Therefore, the "Luoluo" company has completely fallen into the pit of new technology. According to past engineering practices, the application of new technology in new models of products should not exceed 30%, and the new "Luoluo" The engine, from the structure to the material, is almost brand new inside and out. Not to mention, the CFRP blade has been tossed until 1970. Although it exceeds the traditional metal-based blade in many aspects, it cannot pass. The bird strike experiment finally had to start a backup titanium alloy plan. This alone has greatly increased the cost, weight and processing difficulty of the new engine. You must know that the processing of titanium alloys has still caused headaches for the world. The problem."

"After such a toss, Rolls-Royce spent more than twice the budget on this engine, and failed to deliver to Lockheed on schedule, resulting in a high amount of late penalty. Coupled with the worldwide economic recession, the sales of "Rolls Royce" cars are also facing great difficulties. In the end, the capital chain broke and it had to declare bankruptcy in 1971. If it weren't for the British government's timely action, it would be split. Became two companies and injected capital into the "Rolo" engine company to help it finally complete the research and development of the new engine. This long-established company will disappear."

Shi Changxu finally finished talking about the history of the "Luo Luo" company's falling pits. He took a sip of the large enamel tea mug at hand to moisturize his throat. Then when he looked up, he found that the child's eyes were dripping. Rotating around, according to his experience, this kid is obviously thinking of some bad idea.

He couldn't help asking: "Zhenhua, what are you thinking about? The idea of ​​"Luo-Luo" company is not so easy to fight."

Tan Zhenhua smiled and said, "Master, I don’t have such a big appetite for the time being. By the way, Master, you just said so much, it’s all about the history of carbon fiber development in the world, so what's the situation in China? ?"

Shi Changxu sighed: "Well, it’s just tears when you talk about it. In fact, it’s not too late for China to start researching carbon fiber. We have been tracking this advanced technology since the early 1960s. But, you are at your age. Children should know what our country has gone through during this period, coupled with the technological blockade imposed on us by Western countries, so for a long time, we have hardly made any progress. It was not until 1975 that this situation was changed. "

Tan Zhenhua quickly asked: "In 1975? What did we do in China?"

"This year, under the leadership of General Zhang Lao, the current Minister of Defense, we organized more than 20 units across the country to carry out technical research and finally developed a barely usable carbon fiber. However, according to its actual performance, it is not enough. Up to the level of the "T200" label of the Japanese "Tongray" company, the carbon fiber with the "T200" label is already an obsolete product in the world."

Tan Zhenhua asked: "But this year is already 1982, and 7 years have passed since this time. Are we not making any progress?"

Shi Changxu continued to sigh: "There is a little progress. As far as I know, from 1975 to now, our country has invested more than 26 million yuan in this project, and now at least the yield rate has improved. However, the cost is even higher than the selling price in the international market. Of course, this price does not have any practical significance, because they will not sell to us at all. What is even more frightening is the higher strength of the "Toray" company. The "T700" label of the product has already begun to be supplied to the market in batches, and I heard that the better performance "T800" has also completed the pilot test and is expected to be put on the market within a year or two."

"So elder teacher, from your point of view, what are the important aspects of our country's difficulty in developing this carbon fiber?" Tan Zhenhua turned into a curious baby, persevering.

Shi Changxu looked at him deeply again and said: "There are many difficulties, lack of talents, lack of basic technology, lack of application environment, lack of support for the entire chemical system, but these are not the key points, there are only two points."

Tan Zhenhua asked again: "So, which two are the most important?"

"Determination and money!"
