Twenty minutes later, Zhou Heng sent several people to the 909 community. When Li Yuanling returned to the room, she first drove the two lolitas to take a shower, and then forced Ning Wanfei, who was drunk, to go back to the room to rest. After simply cleaning the house, she sat on the sofa with a smile and listened to Liang Yuan popularizing gas turbine knowledge for Ning Wanjia.

"After listening to Xiaoyuan, I feel Aunt Liang is so awesome." Ning Wanjia looked at Li Yuanling and ran to Li Yuanling and leaned comfortably in Li Yuanling's arms.

"Jia Jia, how old are you still in my mother's arms?" Liang Yuan said with a smile.

Li Yuanling looked at Ning Wanjia's blushing face, reached out to pay attention to Ning Wanjia's straight face and said with a smile: "Jia Jia, don't pay attention to him, Xiaoyuan is jealous."

With Li Yuanling's support, Ning Wanjia proudly said to Liang Yuan: "Xiaoyuan, why don't you lean over and try it too? See if Aunt Liang kicks you away."

Liang Yuan looked at his mother with a smile on his face, touched his nose and smiled and changed the subject.

"Mom, haven't you told me that you didn't inform the relevant departments?" Liang Yuan asked curiously.

In China, relevant departments must not offend Li Yuanling. With Li Yuanling's character, they will not be unable to see this. Therefore, Liang Yuan is very curious about Li Yuanling's failure to notify the news organizations and relevant departments.

"Xiaoyuan also knows that the gas turbine project began with the Navy's power supporting system. Li Yuanling asked."

"Well, I remember what my mother and Mr. Wu said before." Liang Yuan nodded and said.

"The gas turbine that was ignitioned today was a completely imitated Spey 1a ship-purchase gas turbine unit. At the beginning, the entire project had no intention of civil use. Therefore, there were some problems with the source of the full set of drawings of Spey 1a." Li Yuanling said with a wry smile.

Although Li Yuanling said something inconsistent with the foreword, Liang Yuan understood what Li Yuanling meant in a second thought.

In the 1980s, Rolls and Rolls were acquired by the British government because of serious losses. In the late 1970s and early 1980s, Rolls and Rolls was still a British state-owned enterprise. It was not until 1987 that Rolls and Rolls resumed privatization.

Before Rolls-Royce privatization, the Republic had already purchased a complete set of production drawings of Spey 1a through some channels, but the relevant technical license licenses did not cost money to buy them. If Spey gas turbines were used on naval ships, the chances of discovering the British were very small, even if the British discovered that the Republic was pirated, they would have to lose money. The military affairs were just that, and your protest would not be effective. However, it would be a bit troublesome for Li Yuanling to invest the gas turbine based on Spey 1a in the civil power generation industry.

If this matter is discovered by Luo Luo and Luo, it is certain to fight a copyright lawsuit. Unless all of Liang Yuan's business has been staying in China and does not have to go abroad, he will definitely face huge fines and compensation. If this matter is not resolved, it will be a very large time bomb.

"There are nearly 20% of the components in the current gas turbine units that we cannot produce in China, including the 3-5-level blades of high-pressure compressors, the turbine discs of high-pressure compressors, the power turbine turbine discs, the inlet nozzles of the flame cylinder..." Li Yuanling said in one breath more than ten core processing technologies of gas turbines.

"My uncle said there is no spare quantity of precision forging, and precision casting equipment has been used for train manufacturing." Liang Yuan said in a daze.

"The accuracy you need on your uncle's side is completely different from that on your mother's side. As long as you have a precise forging part, the car manufacturer's pass is close to 100%, and the pass rate on your mother's side is less than 2%.

For Northeast Locomotive Factory, controlling the accuracy to units below millimeter level is enough to meet the needs of Northeast Locomotive Factory in the next five years. For high-precision gas turbines, the accuracy of parts is the same as Su Liangyu's chip laboratory.

Currently, a gas turbine unit requires about 500 fan blades of various types. With a processing success rate of 2%, a gas turbine requires 50,000 blades to be processed before a qualified finished product can be assembled. This probability of production and processing technology is simply a joke in addition to defrauding national funds.

Liang Yuan smacked his lips and felt a little overwhelmed. No wonder I didn't notify the relevant departments and news units. For the gas turbine laboratory without fraud, the current results can only be considered phased, and the real industrial production is still several streets short of it.

"The core equipment of the new gas engine is now disassembled from the SBE Aviation engine. In order to increase the power and be suitable for use on the ship, SBE Navy changed the original five-stage axial flow fan into a three-stage fan and a two-stage low-pressure compressor. Therefore, the newly added three-stage fans and two-stage compressors cannot be disassembled and can only be produced by ourselves. As a result, the total number of low-pressure compressor blades that were redesigned by these two-stage stages was processed, and the total number of low-pressure compressor blades was less than 40. The forging process was continuously improved, and a total of 3,000 were forged, but not enough qualified products were obtained. In the end, I found a fitter to find blades with no problem from the waste pile, and then I corrected them manually. "

"Xiaoyuan, my mother and teacher discussed it. If you want to complete the localization of Spey, the British Rolls-Royce Company is a hurdle that cannot be avoided. Without Rolls-Royce's technical support, it depends entirely on ourselves. Even if the funds are sufficient, it will take ten years to form a technical breakthrough."

Li Yuanling sighed and continued: "My mother did not consider the production process carefully before, but she did not expect that a large number of parts would be unqualified when operating according to the process flow."

Liang Yuan didn't feel much surprise. In the 1980s, all Chinese people did not know enough about the difficulty of processing aircraft engines. In Liang Yuan's previous life, even if the New Century Spey engine was successfully announced, the domestic production rate was only 99%. The high-pressure turbine guide blades located at the high-temperature gas outlet still needed to be imported from the British Rolls-Royce Company because they involved the technology of fine casting composite cooling hollow turbine blades without margin. This problem was not completely solved until two years later, and half of the first decade of the New Century had passed.

When Xifei Airways was domestically produced SBB, he also encountered the difficulties that Li Yuanling encountered now. No matter how the fine forging technology is improved, it cannot reach the level described in the document. When he went to Luoluo, he visited other people's equipment and his own. Until later, the Republic found a large aviation repair factory with the same fine forging equipment in Israel. It was agreed that when he could only see but not ask, a workshop director of Xifei's workshop keenly discovered that the moment the forging hammer fell, the moment the forging hammer fell was several seconds later than the domestic process flow. The highly inspired workshop director went back to China to imitate the Israeli factory and finally solved the problem of the serious low yield rate of parts using fine forging technology.

It is definitely a slight mistake in real industrial production. If you buy a production line and master a technology, India will have long become the world's most advanced industrial country. There will never be a class brother like the big brother of the Soviet Union who will teach you step by step again. Liang Yuan sighed and thought.

"Xiaoyuan, since we have to resume contact with Rolls-Royce and rely on Rolls-Royce's technical guidance to solve the problem of domestic production of Spey engines, it is no longer feasible to secretly copy Rolls-Royce's naval gas turbines. Before solving the production license, except for the two units we used by Lanhua, there is almost no possibility that Xiaoyuan wants to mass-sell gas turbine generator sets." Li Yuanling said guiltily.

Liang Yuan saw that his mother felt a little guilty, grabbed her hair and said with a smile: "On the chip laboratory, Lao Su and I have made several new projects. At present, everything goes well. At least three or four results can be produced in the first half of the year. So my mother is not going well, and my mother is very smooth, which is very consistent with the objective laws of scientific development."

Li Yuanling heard Liang Yuan’s headless sentence, and was stunned at first, and found that Liang Yuan was extremely cunning, and then suddenly remembered the famous saying “Failure is the mother of success”

Looking at Liang Yuan's relaxed look, Li Yuanling felt warm in her heart. The depression and boredom of some parts of the gas engine could not complete the domestic production as expected. She casually sorted out the sofa cushion at hand. Li Yuanling smiled and said, "Mom just now realizes that the benefits of having a son like you are more than trouble."

Ning Wanjia, who was leaning in Li Yuanling's arms, was simple-minded. After hearing Li Yuanling's words, she couldn't help but mutter in a low voice, "Xiaoyuan is not troublesome at all."

Ning Wanjia's little complaint was clearly heard by Li Yuanling, who had a sharp ear, and patted the little girl's pink cheeks. Li Yuanling smiled and said, "Okay, it's not troublesome. Aunt Liang said the wrong thing. Jiajia married and was also in the same relationship with that boy. Aunt Liang loved you in vain for so many years."

The little girl who was talking and said that she was shy and looked at Liang Yuan withstood her smile. Even her white pink neck turned into a seductive pink color, and she hid her head in Li Yuanling's arms and refused to show it again.

Li Yuanling smiled and scattered Ning Wanjia on her shoulders, and she tidied her straight hair on her arms into a bunch. She stared at Liang Yuan for a while and then asked curiously: "Xiaoyuan, I always heard from Lao Su that you are a first-class investor. My mother is very curious. In the gas engine project, what will Xiaoyuan do if he doesn't consider family relationships now? As my mother said just now, only 2% of the parts yield rate should be a huge disaster for investors."

Liang Yuan smiled and said, "Mom, if you are not in this circle, I will be lazy to come in and tread this muddy water in the pool."

Li Yuanling grabbed the cushion beside her and threw it and said, "Don't go around with her mother. I mean, if you have invested in it and hear that the key components are only 2% yield, what decision will you make?"

Liang Yuanxin said that if it weren't for my mother being the chief engineer, of course, I would have to hide as far as I could. Without the support of the state, the aviation engine would not be something that enterprises dare to test. However, in order to build confidence for my mother, Liang Yuan would not dare to explain truthfully. If my mother felt guilty about losing money, she would be miserable. At that time, the entire layout around the aviation engine would have to be completely defeated. Welcome to your support, which is my greatest motivation. m
