Chapter 30 Dawn

If the modified fan that Li Yuanling made on the SBE engine is considered successful based on the scientific research level of the Republic at this time, it would be fine.

The original SBB before Li Yuanling's modification has the performance of the military thrust of 54.5kn, the afterburner thrust is 91.1kn, and the overall mass of the aircraft engine is 1850kg.

After Li Yuanling replaced the new fan, the military thrust of Novosco became 61.58kn, the afterburner thrust was 98.18kn, the overall mass of the aircraft engine was 1660kg, and the push ratio increased from the original 5.05 to 6.03.

If you throw this new Speyer to the present moment of gritting your teeth and developing the JH-7 Navy, it is definitely a project that can be submitted.

"Xiao Gu, FAW has no project nodes to urge you. Besides, the modification in front of you has only changed the fan, structure, and material, which is not a new model."

"According to my estimate, after replacing the swept blades, the wall loss of the intake airflow should be greatly improved, and the intake efficiency and total pressure will be greatly improved. The data of increasing military thrust by 13% is a bit small."

"Sister Li is so amazing. I feel incredible that it can reach 13%."

"Wait for the supercomputer, we have finished all the simple things we can do, and the further requirements are getting higher and higher."

Li Yuanling sighed with some emotion.

At this time, Li Yuanling naturally didn't know that she was on the right path.

According to the study of swept blades by Pratt & Whitney in the United States after the new century, other factors remain unchanged on the same aircraft engine. After only all the blades including fans and compressors are swept, the thrust of the aircraft engine can be increased by up to 23%.

Of course, whether this effect can be achieved depends on the design skills of the technicians. After the new century, Liu Jusheng, a famous aviation expert of the Republic's Academy of Sciences, once revealed the root cause of the Republic's backward aviation engines.

Academician Liu pointed out bluntly that the backward aviation engines of the Republic are not because of the lack of materials. The lack of top designers is the main factor in the Republic's inability to manufacture advanced aviation engines.

For example, in a series of modifications of SBE aircraft engines in the United States, Allison and Rolls-Royce jointly pushed the maximum thrust of the code-named TF American version of SBE to 110kn from a design perspective by expanding the aircraft engine diameter and adjusting the fan and compressor.

Of course, the methods used by Rolls-Royce and Allison to improve the TF series aircraft engines are very simple and crude. They directly use the method of expanding the diameter of the aircraft engine to increase the intake volume. When the pipe is thicker, the intake will be more. The more intake air in the front, the more exhaust gas is equivalent to the more thrust gas in the rear, and the more thrust gas is naturally greater.

Compared with Li Yuanling's high-difficulty sweeping fan with a stable external size, the pipe diameter is at least one generation short of the difference. If Li Yuanling uses the TF series with the expanded aircraft engine diameter to perform fan modification test, it can increase the thrust of 110kn to 124kn.

"Sister Li, what should I do after the twenty-eight standard cycle tests are passed?"

"Xiao Gu, you are so sincere, of course, you will continue to change. The steel receiver is replaced with resin, the front blade of the compressor can be replaced with aluminum alloy, and the nickel-based turbine disc can be replaced with single crystal alloy. The supercomputer is being optimized and optimized. After the modification, the push ratio is almost enough. If the new blade has no problem, the material replacement is enough for at most two years, then FAW will be able to take the new ship to the Navy to exchange for some pocket money."

"The 7 aircraft engine with a push-by-bike fell from the sky, and the people who were involved in the J-H-7 were still very happy."

This time, FAW Power Datong Gange conducted a standard cycle test. In addition to improving FAW's design and testing standards in the field of aero engines, Li Yuanling has the main purpose of verifying the long-term performance of the swept blades and further mastering the cycle parameters of the Spey core aircraft.

"If the standard cycle test is successfully passed, Xiao Gu remembers to give Xifei an invitation letter to the name of 1,000 yuan, and say hello to Xifei for the push-by-7 Spey. The engine will naturally be beautiful when the aircraft is ready, and it will be better than the old goods in the warehouse in Xifei."

Gu Haiyun nodded when he heard this.

While the two were talking, Li Yuanling read the data on the file. As the sky got late, the FAW employees who went to the park across the river for dinner returned to the test workshop one after another. A lot of people gathered near the huge metal box that was tested in the bench.

"Mr. Li, the supercomputer on Inspur said it was coming soon since last month. It's almost here. There is no movement yet. When will it be until now?"

Half of the FAW call Li Yuanling, Mr. Li are new employees who only joined after Yuanjia acquired Jardine Mahjong.

"Where did your group have dinner today, Xiao Wang?"

Li Yuanling did not answer the question and asked about the staff’s dinner first.

"We rode a bike across the river to eat. The new canteen on the island is all the apprentices of the old canteen master. The taste is always a little bit worse."

"Mr. Li, I'm not saying that the new canteen is not delicious. If it is not considered an old canteen, the dishes in the new canteen will definitely be the best in the province."

Wang Liqiang grabbed his hair and answered a little embarrassedly.

After the institutional reform, FAW has moved closer to the Hong Kong-based current collection system and adopted a flexible working system without a fixed working hours. Of course, engine research and development and electronic research and development are ultimately different.

The difference between the flexible working system of FAW and Hong Kongji Electric Co., Ltd. is that Hong Kongji Electric Co., Ltd. can clock in and get off work at any time all day. It is not casual in the early morning or the second half of the night. HuaWen clock in and get off work at will. The time period for clock in and get off work is controlled between 5:00 and 22:00 every day.

Of course, FAW's assessment is similar to that of Hong Kong-based power collectors. It is a pleasure for you in normal times. As long as you can handle the development nodes according to the progress during the assessment, otherwise the painful downgrade system will be waiting for you. When the R&D level is reduced, the Human Resources Department will definitely not be stingy with a dismissal list.

Given the difficulty in mixing the taste, many foodies in the new workshop check in and get off work at meal time, then ride a bike across the river and back to the old park for dinner. After dinner, they ride a bike back from the other side of the river.

Although you can clearly see the main entrance of the Science and Technology Park when standing on Changbai Island, after the foodies returning to the old park set off from Changbai Island, they traveled 4.5 kilometers east on Hedi South Road to cross the river through the newly built Wulihe Bridge. After crossing the river, they walked 4.5 kilometers west along Hedi North Road to be counted as meal time. If the length of the Wulihe Bridge is included, the brave foodies who have to travel back and forth for at least 20 kilometers.

"You don't feel tired if you go back and forth with a meal for more than 20 kilometers." Li Yuanling said.

"After a few days, our group said we would swim over with a swimming ring. The width of Hunhe River is more than 300 meters long, and it will be much faster than riding a bicycle to cross the river."

"It's not enough to go into the water. It's too dangerous. The group is also considering whether to buy two ferries to facilitate transportation with the island and the headquarters. Xiao Gu, you go to the logistics tomorrow and remind the logistics to remind the entire group that whether you go to and from get off work or use three meals to have a late-night snack, it is prohibited to use swimming to cross the Hunhe River. Violators will be demoted."

After reminding Gu Haiyun, Li Yuanling also felt that the notice was not very tuned and couldn't help laughing.

After laughing at this, someone talked about the topic of supercomputing, and Li Yuanling remembered that there was another problem that had been interrupted just now.

"Xiao Wang just mentioned when the supercomputer will arrive. As far as I know, supercomputer has been successfully developed. However, since the yield rate of manufacturing internal control chips for high-traffic routers is very low, it is not our turn to the first batch of products. However, after Inspur completed the first batch of supply, we, FAW, will definitely be the first department to get supercomputer."

After nearly a year of hard research and development, Wang Xin and his team finally passed the hurdle of high-traffic routers, and the Inspur machine group supercomputer system entered the final testing stage.

Due to factors involved in the field of thermonuclear weapons, Liang Yuan did not know that all the supercomputer's level cards have been successfully resolved. Li Yuanling was able to know the news because she communicated frequently with Su Liangyu.

In mid-April, the new generation processor core named C3, named C3, was successfully streamed one month ahead of schedule, and the main frequency of most C3 processors oscillated in the range of 30-36mhz.

However, what is surprising is that the production line has cut a very small number of elite versions of C3 processors, and its main frequency is extremely high to 54-60mhz.

Wang Xin used the elite version of the C3 processor as the foundation, and combined with the external circuits that had been prepared, the router project that had been stuck for a long time finally came to fruition. The router with a maximum traffic volume of up to 2.6m finally jumped past the difficulty of data blockage.

The excited Inspur team collected the elite version of the C3 processor produced by this streaming, and manually modified nearly 100 2.6m routers to enable the final test of the group supercomputing system.

After the Inspur workstation was upgraded to a C3 processor, the number of floating-point operations of each computing node reached 40 million per second. Wang Xin assembled 80 Inspur operations base stations in one go, directly pushing the number of supercomputing operations to 3 billion times per second. Then this test product was booked by a mysterious department.

Although Su Liangyu didn't know that the supercomputer had started the final test, all the supercomputer chips were provided by Hong Kong-based power collectors. For technical experts like Su Liangyu, you can guess the actual situation of the supercomputer by just writing and calculating. Li Yuanling naturally got rough news.

If you didn’t know that the supercomputer was about to be developed successfully, Li Yuanling would not have started the standard cycle test of the sweeping blades. The supercomputer is coming soon and you will get a lot of actual data without testing. How could you know whether FAW’s exploration on sweeping blades in recent years is right or wrong? In which direction should FAW continue to move forward in the next step.

"It would be great to be the first to get it. Our department has saved too much data waiting for verification and processing. It depends on manpower to calculate it according to the calculator. Everyone has to count it for 70 years when they work together."
