After Liang Yuan calmed down, he felt suspicious. In his previous life, he thought that Speyer's change to the turbine was something that was created by the local method. On the Internet, he occasionally heard that Speyer could not change to climate, and after the test drive, the fuel consumption was high, the power was low, the unit life was very short, etc. However, Liang Yuan had never mentioned these bullshit words with Li Yuanling because of this issue. Because of this issue, Liang Yuan, who was hkc, had debated with others. The new technology generally required maturity time. Even if the first generation had defects, it was normal. Now, I heard that Wu Laoyi said that this machine should be copied according to the drawings of Speyer S_m1a gas turbine. It should not be as unbearable as what he said in his previous life.

Wu Zhonghua continued: "Unfortunately, after the end of the British-Ama War in 1982, two British Type 42 destroyers sank and one seriously injured. The senior navy's voice was dissatisfied with the Type 42 destroyer. In addition, the national economic focus shifted, the Type 051s missile destroyer was cut off in 1984. At that time, the performance verification aircraft of the SBB had been ignited and operated for more than 60 hours.

Wu Zhonghua looked at Li Yuanling pointing at the machine face below with confusion and said, "At that time, the hospital was carrying out reform and testing the integration of industry, education and research. The teacher applied to establish a reorganization enterprise and found the 423 factory under the General Secretary, and persuaded them to launch the gas turbine project to lay the foundation for the ship power business. After the gas turbine was successfully developed, it was produced by the 423 factory alone. Since then, the SBB has become a self-raised funding model for subsequent research and development."

"After 1986, the hospital allocated more than 2 million yuan one after another, and gave up without seeing the hope of profit. Only Factory 423 was left to support the ship's power manufacturing business in order to launch its ship power manufacturing business in the future. After the gas turbine was finalized, it would cooperate with the Navy to test on the 053 frigate. If it was purchased by the Navy, Factory 423 could continue to invest and conduct in-depth research. Unfortunately, the Navy had a few days ago, saying that we were too slow to make progress. Even if we could achieve the expected goal and achieve the power level of 13,800 kilowatts of the original SB s_m1a single unit, the Navy would not purchase in large quantities. The Navy's senior management has taken a fancy to General Electric's lm2500 gas turbine, and the power of the LM2500 single unit can reach 22,500 kilowatts, which is much higher than SB ."

Wu Zhonghua sighed long and said, "Xiaoling, the teacher didn't expect that things would turn out like this just after you were transferred to you. Now the gas turbine is about to conduct a test of the whole machine, but this kind of accident occurred on the Navy."

Li Yuanling said comfortingly: "It's okay, at the worst, I will go back to Peking with my teacher to do research. Besides, it took only two years from the performance verification machine to the entire machine test drive. The teacher's progress is already fast enough."

Wu Zhonghua heard Li Yuanling say this and shook his head and said with a wry smile: "Where is our progress is fast? The verification machine only ignitioned for 60 hours, and even the full life of the compressor after cutting the top was not done. In order to make the unit power exceed 15,000 kilowatts, Factory 423 modified the design of the air cooling system and the axial force of the engine inside the engine. However, in order to save money, it was directly fixed after normal calculations, and no quantitative verification was done at all. There are many examples like this. This equipment takes the path of testing the whole machine first, and then correcting where the problem occurs. It is completely opposite to the path of verifying key components abroad, and finally doing the whole machine verification."

Wu Zhonghua said with some pain: "Even if you are eager to take the Navy project, you cannot violate the scientific laws. This is not to understand it very much. Install the whole machine first to test the operation. It is best to have no problems. If you have problems, you will be cured by headaches. How many years will it take to fully understand Spur’s technology."

Liang Yuan then suddenly realized, thinking that no wonder the first test run data of SBE modified in his previous life was so ugly. Factory 423 did not realize the complex production and design difficulty of gas turbines. Is this a random thing changed? The first test run data was ugly, probably putting the blame on Wu Zhonghua. After all, Mr. Wu was the leader of the project, and then Factory 423 lost its investment as a project. The Navy had not taken a fancy to SBE modified in advance. This time the reason was more sufficient. Domestic things just didn't work. They couldn't produce drawings for you. The call for lm2500 gas turbines would definitely be louder. It is estimated that Mr. Wu was hospitalized at the end of the year because of this incident, and finally died of overwork in 1989. Liang Yuan stood aside and listened to Wu Zhonghua's discussion of the ins and outs of SBE modified, and basically guessed what happened in his previous life.

Wu Zhonghua pointed to the unit under his feet and said, "Xiaoling, the teacher originally planned to install two prototypes, one of which is the current simple circulation unit, and the other with an intercooling and heating system. Unfortunately, the project team did not have enough funds."

Li Yuanling asked curiously: "How much does this unit cost now?"

"The other costs are not counted. The unit alone is about 11 million yuan. The main reason is that our Spey engine production line has been closed. The gas generator inside is modified from imported Spey engines, which takes up more than half of the cost."

The three of them circled around the machine for a few times. Wu Zhonghua taught Li Yuanling for a while, and Liang Yuan, who was pricking up his ears and eavesdropping, was dizzy and thought that he was indeed not the material for this job. Seeing that my mother and Mr. Wu were both looking golden, Liang Yuan was wandering around the workshop.

Two hours later, Liang Yuan, who had long lost interest, and the two people who had not finished talking about sex returned to Wu Zhonghua's office. Wu Zhonghua took out a bag of tea and smiled at Li Yuanling and said, "What about the authentic Longjing, Xiaoling, you are a blessing."

Liang Yuan looked at his mother as if she was expecting, wondering why his parents loved to drink tea, so why did he have no interest in this national treasure? He still felt that coffee was more suitable for two lifetimes, and he was a common person.

Wu Zhonghua slowly injected boiling water into the teapot, looking at the steaming mist, and continued: "Director Hong came to ask about oil. If the original SB s_m1a is running at full capacity, it will consume three or two tons of oil per hour. I asked the 909 Institute to prepare according to three tons per hour."

Liang Yuan was a little confused. Could it be that ours is more fuel-efficient than the original one, and asked: "Is Grandpa Wu our gas turbine more fuel-efficient than the original one?"

Wu Zhonghua laughed and said, "Where is our fuel savings? I guess our maximum power must be smaller than the original ones." Li Yuanling looked at Liang Yuan and was confused. He picked up a pen and wrote a few numbers on the paper and handed it to Liang Yuan. Liang Yuan took it and saw that the maximum power of SB s_ma1 was 13,800 kilowatts, and the fuel consumption rate was 235 grams/kilowatt hour. Li Yuanling pointed to the two data and said, "Xiaoyuan multiplied these two data and knew the fuel consumption at full power."

Liang Yuan looked at the data on the paper and remembered the speed of the 054 frigate of the later generations of the Tubi Navy, which had only 27 knots and a week of maritime self-sustainment. He thought that even if it was replaced with a gas turbine of the SB 1 level, the full load displacement of the 054 frigate could be increased from 4,000 tons to 5,000 tons, and its combat capability could be increased by at least 30%, and it could keep up with the high speed of 30 knots of the aircraft carrier formation.
