First, the modified fan that Li Yuanling made on the Spey aero engine is not inappropriate if it is considered a success according to the scientific research level of the Republic at this time.

THE PERFORMANCE OF THE ORIGINAL SPEY BEFORE LI YUANLING'S MODIFICATION IS MILITARY THRUST OF 54.5KN, AFTERBURNER THRUST IS 91.1KN, AND THE OVERALL MASS OF THE AERO ENGINE IS 1850KG.

After being replaced with a new fan by Li Yuanling, the military thrust of Xinspei became 61.58KN, the afterburner thrust was 98.18KN, the overall mass of the aero engine was 1660KG, and the thrust ratio was increased from the original 5.05 to 6.03

If this new Sibei is thrown to the current gritted teeth to develop the Jian-H 7 Navy, it is definitely a project that can be handed over.

"Xiao Gu, Brilliance has no project nodes to urge, and besides, the modification in front of me has only changed the fan, and the structure and materials have not moved at all, which is not a new model. ”

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

"Sister Li is really amazing, I think it's incredible to have 13%. ”

"Let's wait for the supercomputer, we have finished all the simple things that can be done, and the requirements for further progress 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 research on swept blades in the United States after the new century, the thrust of the aero engine can be increased by up to 23% after all the blades including fans and compressors are swept by the same aero engine.

After the new century, Liu Jusheng, an academician of the Academy of Sciences of the Republic of China and a well-known aviation expert, once said that the root cause of the backwardness of the Republic's aero engines was broken.

Academician Liu bluntly pointed out that the backwardness of the Republic's aero engines is not due to the lack of materials, and the lack of top designers is the most important factor in the Republic's inability to manufacture advanced aero engines.

For example, in a series of modifications of Spey aero engines in the United States, Allison and Rolls-Royce jointly pushed the maximum thrust of the code TF Spey to 110KN from a design point of view by expanding the diameter of the aviation engine, adjusting the fan and compressor, without using new materials.

Of course, limited to the times, Rolls-Royce and Allison to upgrade the TF series of aero engines used by the means are very simple and crude, directly by expanding the diameter of the aero engine to increase the air intake, the tube is thicker, the intake is more, the front air intake is equivalent to the rear exhaust more thrust, and the thrust is naturally larger.

Compared with Li Yuanling's difficult grazing fan that does not move the external size, changing the diameter of the pipe is at least one generation worse, if Li Yuanling takes the TF series with the expanded diameter of the aviation engine as the basis for the fan revision test, the thrust of 110KN can be increased to 124KN.

"Sister Li, after the twenty-eight standard cycle tests are passed, what will I do with this engine?"

"Xiao Gu you can be honest in this heart, of course, it is to continue to change, the steel casing is replaced with resin, the front blades of the compressor can be replaced with aluminum alloy, the nickel-based turbine disc can be replaced with a single crystal alloy, and the swept blades of the supercomputing offline line are being optimized and optimized, so that a few changes to the estimated touch and push ratio should be enough to 7, if the new blade is okay, the material replacement is enough for two years at most, then Brilliance will be able to take the new hair to the navy to exchange some pocket money. ”

"A 7 aero engine fell from the sky, and the gang of people who engaged in the J-7 were still dizzy. ”

In addition to improving Brilliance's design and testing standards in the field of aero engines, Li Yuanling verified the long-term performance of the grazing blades and further mastered the cycle parameters of Spey's core engine.

"If the standard cycle test passes successfully, Xiao Gu remembers to send an invitation letter to Xifei in the name of the thousand, and say hello to Xifei about the modification of the Tubi 7 Spey, and the data of the aircraft will naturally be beautiful when the engine is good, which is better than the old goods in the warehouse of Xifei. ”

Gu Haiyun nodded when he heard this.

While the two were talking, Li Yuanling finished reading the data on the document, and as it got getting late and late, the Brilliance employees who went to eat in the park on the other side of the river returned to the test workshop one after another, and after a long time, many people gathered near the huge metal box of the bench test.

"Mr. Li, the supercomputer on the other side of the wave has said since last month that it is coming soon, and it is coming soon, and there is no movement yet, when will it be. ”

In Brilliance, half of the people who call Li Yuanling and Mr. Li are all new employees who joined Yuanjia after acquiring Jardine Matheson.

"Xiao Wang, where did your group eat today?"

Li Yuanling didn't answer the question, and asked about the employee's dinner first.

"We rode across the river to eat, and the chefs of the new canteen on the island were all apprentices of the old canteen master, and the taste always felt a little worse. ”

"Mr. Li, I'm not saying that the new canteen is not delicious, if it is not the old canteen, the dishes in the new canteen must be the first in the province. ”

Wang Liqiang grabbed his hair and replied a little embarrassed.

After the system reform, Brilliance has moved closer to the Hong Kong-based power collector, and has adopted a flexible working system, without a fixed commuting time, of course, engine research and development and electronic research and development are different.

The difference between the flexible work system of Brilliance and Gangbase is that Gangji can clock in and out at any time throughout the day, not in the early morning or in the second half of the night, and Brilliance clocks in and out at will, and the time period for clocking in and out of work is controlled within the time period from 5 o'clock to 22 o'clock every day.

Of course, Brilliance's assessment is similar to that of Hong Kong-based power collectors, as long as the development node can be completed according to the progress of the assessment, otherwise the painful downgrade system will be waiting for you, and when the R&D level is downgraded, the personnel department will definitely not be stingy with a list of dismissals.

In view of the difficulty of adjusting the taste, many foodies in the new car room clock in and out of work at mealtime, and then ride across the river to the old park for dinner, and then cycle back from the other side of the river after eating.

Although standing on Changbai Island, you can clearly see the main entrance of the science and technology park at a glance, but after the foodies who go back to the old park start from Changbai Island, they can cross the river through the newly built Wulihe Bridge by going east for 4.5 kilometers on the South River Road, and after crossing the river, they will travel 4.5 kilometers west along the North River Road to get to the meal, and if the length of the Wulihe Bridge is counted, the brave foodies will have to travel at least 20 kilometers before and after.

"It's more than 20 kilometers back and forth for a meal, and you are not too tired. Li Yuanling said.

"After a few days of warm and warm, our group said that we would swim over with a swimming ring, and the width of the Hunhe River was more than 300 meters, and it took ten minutes to swim there, which was much faster than crossing the river by bicycle. ”

"It's not possible to go into the water, it's too dangerous, the group is also considering whether to buy two ferries to facilitate the transportation between the island and the headquarters, that Xiao Gu, tomorrow you go to the logistics, remind the logistics within the scope of the whole group, whether you go to work or have three meals and supper, it is forbidden to cross the Hunhe River by swimming, and the offender will be demoted. ”

After reminding Gu Haiyun, Li Yuanling also felt that this notice was not too out of tune, and couldn't help laughing.

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

"Xiao Wang just mentioned when the supercomputer will arrive, as far as I know, the supercomputer has been successfully developed, but due to the low yield of the internal control chip of the manufacturing of high-traffic routers, the first batch of products is not our turn, but after the Inspur completes the supply of the first batch, we Brilliance must be the first department to get the supercomputer. ”

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

Due to factors involving the field of thermonuclear weapons, Liang Yuan did not know that all the levels of supercomputing had been successfully solved, and Li Yuanling was able to know the news because of frequent communication with Su Liangyu.

In mid-April, the new generation of processor cores named C3 was successfully taped out one month ahead of schedule, and the main frequency of most C3 processors fluctuated in the range of 30-36MHz.

However, what is surprising is that the production line has cut a very small amount of elite version of the C3 processor, and its main frequency is as high as 54-60MHz.

Wang Xin used the elite version of the C3 processor as the foundation, and after matching the external circuits that had been prepared for a long time, the router project that had been stuck for a long time finally came to fruition, and the router with a maximum flow rate of up to 2.6M finally jumped over the difficulty of data jamming.

After collecting all the elite C3 processors produced by the tape-out, the excited Wave team manually changed nearly 100 2.6M routers to start the final test of the cluster 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, and Wang Xin assembled 80 Inspur computing base stations in one go, directly pushing the number of supercomputing operations to 3 billion times per second, and 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 chips of the supercomputer were provided by Hong Kong-based power collectors, for a technical expert like Su Liangyu, he could guess the actual situation of the supercomputer with a casual calculation, and Li Yuanling naturally got the general news.

If it weren't for the fact that the supercomputer was about to be successfully developed, Li Yuanling would not have started the standard cycle test of the swept blade, and now that the supercomputer is coming, if a large amount of actual data is not obtained, how can we know whether Brilliance's exploration of the swept blade in the past few years is right or wrong, and in which direction should Brilliance continue to move forward next.

"It's great to be the first to get it, our department has saved too much data waiting to be verified and processed, and it depends on manpower to calculate it by calculator, and everyone has to count 70 years together. ”

After working in Brilliance for a long time, even if no one says it and many people know it, the first supercomputer must have been taken away by the military and used in the defense field that urgently needs supercomputing systems.
