After Liang Yuan calmed down, he was suspicious, in his previous life, he thought that Spey's refueling turbine was something made by the soil turtle method, and he occasionally heard on the Internet that Spey could not change the climate, and the fuel consumption was high after the test, the power was low, and the life of the unit was very short, etc., but Liang Yuan was afraid that his mother would be sad, and these bullshit words were never mentioned to Li Yuanling. Because this issue is still HKC's Liang Yuan has debated with others, new technologies generally need time to mature, even if the first generation is defective, it is normal, etc., now I heard Wu Laoyi say that this machine should be imitated according to the drawings of the Spey S_M1A gas turbine. Then it shouldn't be as unbearable as it was said in the previous life.

Wu Zhonghua continued: "It's a pity that after the end of the Anglo-Argentine war in 1982, two British Type 42 destroyers sank and one was seriously damaged, and the top of the Navy was dissatisfied with the voice of the Type 42 destroyer, coupled with the shift in the focus of the national economy, the Type 051S missile destroyer was cut down in 84, when the Speygai's performance verification machine had been ignited and operated for more than 60 hours.

Wu Zhonghua looked at Li Yuanling and pointed to the machine below with a puzzled face, and said: "At that time, it was just in time for the restructuring of the courtyard and the integration of production, education and research, so the teacher applied for the establishment of a restructuring enterprise and found the 423 factory under the general headquarters, persuaded them to start the gas turbine project, lay the foundation for the development of the ship power business, and promised that the gas turbine would be produced by the 423 factory alone after the successful development. Since then, Spey has changed to a self-funded model for follow-up research and development. ”

"After the hospital allocated more than 2 million yuan in 86 years, I gave up without seeing the hope of making a profit. Only the 423 factory is left, and in order to be able to launch the ship power manufacturing business in the future, it is struggling to support it. Originally, it was planned that after the gas turbine was finalized, it would cooperate with the Navy to test it on the 053-class frigate, and if it was purchased by the Navy, Plant 423 could continue to invest in in-depth research. It's a pity that a few days ago, the Navy came out with news, saying that our progress is too slow, even if we can complete the expected goal, to reach the power level of 13,800 kilowatts of the original Spey S_M1A unit, the Navy will not purchase a large number of them, the navy 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 Spey. ”

Wu Zhonghua let out a long sigh and said: "Xiaoling, the teacher didn't expect that things would turn out like this just after you were transferred, and now the gas turbine is about to undergo the ignition test of the whole machine, but there is such an accident in the navy." ”

Li Yuanling said comfortingly: "It's okay, at worst, I'll go back to Beiping with the teacher to do research, and besides, it took only two years from the performance verification machine to the whole machine test, and the teacher's progress is fast enough."

Wu Zhonghua heard Li Yuanling say this, shook his head and said with a wry smile: "Where is our fast progress, the verification machine has only been ignited for 60 hours, and even the whole life operation of the compressor after cutting the top has not been done, in order to make the power of the unit exceed 15,000 kilowatts, the 423 factory has modified the design of the air cooling system inside the engine and the axial force of the rotor, but in order to save costs, it has been directly finalized after general calculations, and no quantitative verification has been done at all." There are many examples like this, this equipment takes the path of testing the whole machine first, and then changing where there is a problem, which is completely opposite to the way of foreign countries to verify key components first, and finally to do the whole machine verification. ”

Wu Zhonghua said with some bitterness: "Even if you are in a hurry to take the navy's project, you can't violate the laws of science, this is not to seek a solution, first put the whole machine out for testing, there is no problem is the best, there is a problem in the headache and the head and feet are painful, how many years will it take to understand Spey's technology." ”

Liang Yuan suddenly realized, thinking that it was no wonder that the first test run of Spey in the previous life was so ugly, and the 423 factory did not realize the complex production and design difficulty of gas turbines, so this thing was changed casually. The number of first test runs was ugly, probably put the responsibility on Wu Zhonghua's head, after all, Wu Lao was the leader of the project, and then the 423 factory withdrew when the project failed, and the navy didn't look at Spey, this time the reason is more sufficient, the domestic stuff just doesn't work, you can't produce the drawings, and the call for the LM2500 gas turbine must be louder. It is estimated that because of this incident, Wu Lao was hospitalized at the end of the year, and finally died of illness in 89. Liang Yuan stood aside and listened to Wu Zhonghua finish talking about the ins and outs of Sibei's change, 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 is the current simple circulation unit, and the other is a unit with an intercooling and reheating system, but unfortunately the project team does not have enough funds. ”

Li Yuanling asked with some curiosity: "Teacher, how much does this unit cost now?"

"Don't count other costs, just refer to this set of units about 11 million, mainly because our Spey engine production line has been closed, and the gas generator inside is an imported Spey engine modification, which will account for more than half of the cost. ”

The three of them circled around the machine a few times, and Wu Zhonghua gave Li Yuanling a live teaching for a while, and listened to Liang Yuan, who pricked up his ears and eavesdropped, dizzy, thinking that he was really not the material for this job. Seeing that Lao Niang and Wu Lao were all looking like they were shining with golden light, the bored Liang Yuan wandered around the workshop.

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

Liang Yuan looked at his mother with an expectant look and wondered why his parents love to drink tea, why he has no interest in this quintessence of the country, and he still feels that coffee is more agreeable in the two lives, a layman.

Wu Zhonghua slowly poured boiling water into the teapot, looked at the steaming mist and continued: "Director Hong came to ask about oil just now, the original Spey S_M1A will consume 3.2 tons of oil per hour when it runs at full capacity, and I asked the 909 Institute to prepare it according to three tons per hour." ”

Liang Yuan was a little confused, could it be that our gas turbine is more fuel-efficient than the original, and asked, "Grandpa Wu, is our gas turbine more fuel-efficient than the original?"

Wu Zhonghua laughed and said: "Where is our fuel saving, I estimate that our maximum power must be smaller than the original." Li Yuanling looked at Liang Yuan who was still confused, picked up a pen and wrote a few numbers on the paper and handed them to Liang Yuan. Liang Yuan took it and looked at it, and it said that the maximum power of Spey S_MA1 was 13,800 kilowatts, and the fuel consumption rate was 235 g/kilowatt hour. Li Yuanling pointed to the two numbers jù and said: "Xiaoyuan multiplies these two numbers jù to know the fuel consumption at full power." ”

Liang Yuan looked at the number on the paper and thought of the speed of the 054 frigate of the Turkish turtle navy in the later generations, which was only 27 knots and a week's self-sustaining power at sea, and thought that even if it was replaced by a Spey S_MA1-level gas turbine, the full load displacement of the 054 frigate could be increased from 4,000 tons to 5,000 tons, and the combat capability could be increased by at least 30%, and it could keep up with the high speed of the aircraft carrier formation of 30 knots.
