Chapter 90: Correct understanding

　　 Fighters need good engines.
　　 Of course, a transport plane also needs a good engine.
　　The speed and flexibility required by fighter jets. What the transport plane needs is high thrust and heavy load.
　　 In the old days, the Soviet An-225 transport aircraft was a real Big Mac. The take-off weight is more than 600 tons, the effective load is more than 300 tons, and the endurance is 15400 kilometers.
　　In front of it, what Airbus A380, what Boeing 747, are all scum.
　　Of course, our country also wants to have An-225.
　　 However, it is a pity that it is out of reach.
　　 my country’s latest military transport aircraft is Yun-20, with a maximum take-off weight of 220 tons and an effective load of more than 60 tons. Roughly equivalent to about one-fifth of An-225.
　　 Well, one fifth.
　　 The weight of a heavy main battle tank.
　　 The maximum range is about 7,800 kilometers. Equivalent to about half of An-225.
　　The key is the thrust of the engine.
　　 Meidi’s C-17 transport aircraft has a single engine thrust of 18 tons. And our country's single thrust is only 12 tons. Only two-thirds of the opponent. The gap is huge.
　　 There is also a giant transport plane from the United States, which is the C-5 Galaxy. Its carrying capacity exceeds 120 tons. The maximum take-off weight is 380 tons.
　　 Why is it so tough? They are all powerful engines!
　　 Of course, the emergence of Yun-20 has also greatly changed the status quo of my country's air force transportation.
　　 Specifically, the Yun-20 can transport most of the technical equipment currently equipped by the China Army, including main battle tanks, armored vehicles, self-propelled artillery and helicopters. If there are 100 Y-20s, one mechanized infantry regiment can be sent to 5000 kilometers away at a time. If it is only to transport soldiers, then 100 Y-20s can project an infantry regiment 7,000 kilometers away at a time, giving the Chinese Army an initial global strategic delivery capability.
　　 From a strategic point of view, the emergence of Yun-20 is almost comparable to domestic aircraft carriers.
　　The only problem is that it needs a stronger heart.
　　 At least, the effective load of Yun-20 needs to be increased to more than 100 tons. The maximum range exceeds 10,000 kilometers. And has the ability to take off and land all-weather.
　　Where did the powerful engine come from?
　　 requires bold design and strong raw materials.
　　 Does Wang Bu'an have it?
Have!
　　He has a package of solutions.
　　 If it is given to him to design, he can completely increase the effective load of Yun-20 to more than 150 tons.
　　 At the same time, the maximum range was increased to more than 15,000 kilometers.
　　 can also be equipped with more advanced electronic equipment. Have the ability to take off and land under any climatic conditions.
　　Even, even in the face of violent storms and snowstorms, this behemoth can look like a giant and is not afraid.
　　 However, he has no such power.
　　 This is the national strategy. It is top secret. It will not be designed by private individuals.
　　 Unless he has the full trust of the country.
　　 "I don't understand the technical problem." Wang Buyan said modestly on purpose, "but I can provide you with a hydraulic machine and a CNC machine tool."
　　 "We have cooperating enterprises ourselves." Han Xuewei shook her head and said.
　　 "But you don't have a 100,000-ton hydraulic press, and there are 1 micron-level CNC machine tools."
　　 "Are you sure you are right? One hundred thousand tons?"
"of course not."
　　 Wang Bu'an answered very calmly.
　　 How could it be wrong?
　　 This data is much easier to remember than the lithography machine.
　　 Han Xuewei looked at Cheng Kailong.
　　 Cheng Kailong was also a little surprised.
　　Han Xuewei was surprised by the 100,000-ton hydraulic press.
　　 Cheng Kailong was surprised that it was a 5-axis CNC linkage machine tool of the 1 micron level.
　　 Immediately, Han Xuewei also reacted.
　　 1 micron level CNC machine tools? That's a cutting-edge product.
　　 At present, in the world, the precision can reach more than 0.05 mm, which is a precision machine tool. How much is 0.05 mm? 50 microns!
　　 Between 1 micron and 50 micron, the difference is too far. He is also very difficult to accept for a while.
　　 "The engine parts require extremely high precision, maybe you can use it?" Wang Bu'an continued.
　　 "If the accuracy of CNC machine tools can indeed reach 1 micron, then we definitely need it." Han Xuewei said slowly.
　　 "CNC machine tools are very expensive. I don't think you can afford them. Why not rent them to you. The daily rent is 10,000 yuan. A 100,000-ton hydraulic forging machine is given as a gift."
　　 "10,000 yuan a day? You really dare to speak loudly! Why not 100,000 yuan a day?"
　　 "Miss Han, the CNC machine tools I provided are definitely worth the money."
　　 "Sorry, I don't have the right to decide."
　　 "That's a pity."
　　 "I want a set." Cheng Kailong said suddenly.
　　 "Thank you very much, then." Wang Buan opened his eyes and smiled, "But what are you doing here?"
　　 "Useful." Cheng Kailong did not answer directly.
　　 "Good. Transaction." Wang Bu'an did not continue to ask.
　　 Others are confidential units, don't be boring.
　　 Anyway, a rent of 10,000 yuan per day, you just don’t want to be in arrears.
　　 Speaking of it, a rent of 10,000 yuan a day is really too cheap! That's a 5-axis CNC machine with a precision of 1 micron!
　　Large forgings, you can find Huaxia Erzhong and forge them with an 80,000-ton hydraulic press.
　　 But, who are you looking for for parts with an accuracy of 1 micron?
　　 There are no 1 micron machine tools in the world.
　　 "But transportation needs to be solved by yourself." Wang Bu'an added.
　　 "No problem. Look at the goods first." Cheng Kailong nodded.
　　 "No problem. You can watch it anytime. However, I only have one set at the moment. If you want it, hurry up."
　　 "Wang Bu'an, you are more and more like a profiteer now."
　　 "Will a profiteer give you such a favorable price?"
　　 "Apart from us, who would easily believe you?"
　　 "……"
　　 Wang Bu'an had no choice but to shut up with interest.
　　 No way, there are so many people who know the goods. Cheng Kailong is barely one.
　　Han Xuewei is absolutely ignorant.
　　 She doesn't believe that there are machine tools with 1 micron precision in this world.
　　 No wonder Yun-20’s heart is slow to progress...
　　Without proper equipment, no matter how well you design it, there is no way to experiment!
　　 You need to know that the engine test process is very cumbersome. At least five engines need to be prepared, and then repeated tests until all of them are scrapped.
　　If it is to obtain more test data, at least ten engines must be prepared.
　　Without an accurate five-axis CNC linkage machine tool, where are so many precision parts?
　　 Rely on senior fitter’s cars to come out one by one? impossible.
　　Manpower is impossible to mass produce.
　　 No matter how good fitter is, it is impossible to meet the needs of the production line.
　　Only CNC machine tools can increase production capacity.
　　 "For you."
"what?"
　　 "You will know when you look at it."
"is it?"
　　 Han Xuewei frowned slightly.
　　Wang Buyan handed it over. It was actually a notebook.
　　 Very old notebook. Plastic cover. The one with a lock. The size should be 32 open.
　　 "I don't watch." Han Xuewei shook her head and said.
　　 "It's okay. You can watch it slowly when you have time." Wang Bu'an didn't care.
　　 Inside the notebook, he actually designed the basic idea of ​​the Yun-20 large aircraft engine. According to this idea, a single engine with a thrust exceeding 30 tons can definitely be produced.
　　 At present, the largest thrust engine in the world is the American F-135, with a single thrust of just over 20 tons.
　　 The 30-ton single aircraft thrust he designed completely crushed this value.
　　 It's a pity that Han Xuewei seems to have misunderstood.
　　 She actually naively thought, what is in the notebook.
　　 Women really can only be used to seductively.
　　Yun-20 large aircraft research project, how can women be allowed to exist? Long hair, short knowledge...
　　 "You have corrected your understanding."
　　 "You gained 10240 faith points."
　　 "You have contributed to the defense industry."
　　 "You gained 10240 faith points."
　　 Suddenly, a message flashed by.
　　 Wang Bu'an can understand the information behind. Only the first...
　　 What does it mean to correct one's own understanding?
　　 Do you think Han Xuewei is not suitable for participating in large aircraft project research?
　　 is really strange, such an idea can actually get faith points? It seems that you can get something for nothing!
　　Twenty thousand belief points, what can be done?
　　 "When I'm ready, I will go to you~EbookFREE.me~ said Cheng Kailong.
　　 "You send me away now. I don't want to watch it." Wang Bu'an said, "I'll wait for the result."
　　 "Alright. I'll take you back first."
　　 "Thank you!"
　　 The two left the military base.
　　Wang Buan breathed a sigh of relief after walking out of the military restricted zone.
　　 He felt that he was finally free again.
　　 Check the watch.
　　 Three missed calls. A message. Five WeChat.
　　 I thought I was very busy, but when I opened it, I found that all of them were phone calls and spam. WeChat is also full of advertisements.
　　 It's not that the robot wizard No. 1 can't isolate these intrusive messages.
　　 This guy doesn't want to at all.
　　 It also feels that these intrusive messages are quite fun.
　　 It will even interact with harassment information. Or pretend to be stupid and lure the other party into the bait. Until the other party broke down.
　　 These anti-routine knowledge are all the robot elves learned from Wang Bu'an's mind.
　　 The former Wang Bu'an, when he was bored, specialized in this kind of detrimental things. Purely to pass the time.
　　 However, he used to be a human brain after all, so he would be tired.
　　 Once I feel tired, I don’t want to continue.
　　 However, the Robot Elf No. 1 is very happy.
　　 It even gathers other robot elves to counter the intrusive messages.
　　 organized.
has plans.
　　 has a scale.
　　 Legion combat. Big Corps fights.
　　 What kind of effect has been achieved, Wang Bu'an is temporarily unclear. But it will definitely be rewarding.
　　 To rectify telecommunications fraud, perhaps rely on Transformers.
