Automotive Black Technology Chapter 1174: : Just today!
www.lnmao.org, the fastest update to the latest chapter of automotive black technology!
Liu Qing and the R&D personnel of Zhengxin Power Company really did not expect that they would be able to work on a project with the First Aerospace Academy one day!
What is the First Aerospace Academy?
The full name is China Launch Vehicle Technology Research Institute, which is the largest research, design, trial production, testing and production base for missile weapons and launch vehicles in China!
The extraterrestrial achievements that carry the dreams of countless astronauts all take off from here. The famous Long March series of rockets are the results of the First Aerospace Academy!
Liu Qing and others smacked their lips as they watched a group of guys who were smiling and silent moving things into the R&D building of Zhengxin Power Company like magic.
With the arrival of these people, the confidentiality level of the Zhengxin Power R&D Department, which can be called strict, suddenly increased.
Everyone's personal USB flash drives and mobile hard drives were all inspected. Even the special treasures on Liu Qing's key chain included SDNM-061, SDNM-064, ABP-171, and other peerless treasures. U disks with a size of more than 60 gigabytes were also ruthlessly confiscated.
Not only that, all the hardware connected to the computer of Zhengxin Power has also been registered by the management team that came with the First Aerospace Institute, and has been stamped with the serial number of the equipment system monitoring hardware.
All computer systems have been downgraded from WIIN7 Enterprise Edition to XP, and the WIFI that the boys in the R&D center rely on for survival has also been blocked. Just five minutes after the guys from the Zhengxin R&D team got themselves several Gigabyte data packages, they sadly discovered that the mobile phone signals within two kilometers of the entire R&D building were blocked.
Li Fanyu looked at Wang Kai, the person in charge of the submarine fuel storage department, and smiled helplessly: "Your level of confidentiality is too high,"
Wang Kai is not old, and looks to be in his early thirties. When he heard Li Fanyu complain, he spread his hands helplessly, "Just make do with it, the ups and downs are temporary. I am in the First Aerospace Academy After working for seven years, no one talks to me on QQ anymore.”
Li Fanyu was stunned, "What's going on?" He pointed to the expressionless safety supervisors around him and asked, "It's been too long and you can't use it anymore?"
"Shit!" Wang Kai spread his hands, "Whoever I talk to will always have their QQ account logged in from another place... and call history roaming will be activated inexplicably..."
"Oh..."
Li Fanyu understood, he shrank his neck, "Haha... then you are really miserable,"
Wang Kai patted his shoulder and said, "It doesn't matter, the job this time is small. Liquid gas storage technology is very popular in China, no, maybe the world. The technical reserves of our First Aerospace Institute should be able to arrange The top three. I got a rough idea of your situation when I came here, and it’s not difficult. I guess I’ll be able to sort it out for you in a week, and you’ll be fine as soon as we leave.”
Li Fanyu grinned. Xin Daojing is talking nonsense and using your technology. As long as the submarine project is not completed for one day, this level of confidentiality will not be withheld for one day!
But seeing Wang Kai’s apologetic and helpless look, he didn’t say anything.
…………
Wang Kai is indeed not a braggart.
The main research and development scope of the First Aerospace Academy is launch vehicles. On the Long March series, the liquid fuel propulsion system has been thoroughly played with. From the dinitrogen tetroxide and dimethylhydrazine liquid fuel boost of Long March 1 to the solid fuel propulsion system used by Long March 10, throughout the development history of the Long March series of launch vehicles, the upgrade of propulsion fuel is very important. One ring.
The storage problem of liquid oxygen and hydrogen that Li Fanyu is currently stuck in was solved by the First Aerospace Institute in 2007 - that is, during the development process of Fat Five.
The main fuels used by the Long March 5 are liquid oxygen and liquid hydrogen.
For current submarines, a stable fuel storage technology is needed. But compared with launch vehicles that often cost more than a billion and are equipped with inestimable extraterrestrial equipment, they are undoubtedly nothing!
So what happened to Li Fanyu was nothing to worry about in the eyes of the researchers at the First Aerospace Academy...
After the initial communication, the two parties started their own part.
For a time, the progress of the entire submarine modification project suddenly accelerated!
…………
Time flies by.
In terms of Zhengxin Power, it is driven by the sincere cooperation with the First Aerospace Academy and the strong processing capabilities of Zhengxin Industrial Base.
After three complete machine simulation tests, the transformation plan for the No. 054 Han-class nuclear-powered attack submarine and the No. 079 and 080 Kilo-class conventionally powered submarines is almost certain to be successful!
After all the assemblies that have been trial-produced in Zhengxin are transported back to the 920425 Submarine Research Institute through warship escort, the final assembly work has been successfully completed!
After the transformation, the power systems of the two Kilo-class submarines are composed of the original two sets of 4DL-42M closed diesel engines, one set of PG-141M general propulsion engines, one set of PG121 generator sets, and two sets of backup emergency power generators The bloated lineup of units was simplified by Wie: a set of 8FV-52B closed diesel engines modified from Poseidon H-V8, a set of ultra-high-power LS-022 fuel power generation propulsion units, and two sets of retained emergency power generation units. unit.
Although it still looks like three parts, after this transformation and upgrade, the power and transmission system of the 054 Han-class nuclear submarine has been simplified to about 2,000 parts. The two Kilo-class conventionally powered submarines 079 and 080 are missing nearly 8,000 parts!
But in exchange for such a huge weight loss, it is an increase in power.
In the three simulation tests, the power system was not severely damaged. Only the cooling system was upgraded. The submersible speed and floating speed of the 054 Han-class nuclear submarine increased by 5% and 7% respectively.
However, the two Kilo submarines that used Zhengxin's new "Hurricane" pump-jet propulsion system, LS-013B large rare earth permanent magnet motor, and new liquid fuel cell API system have increased their submersible speed from 18 knots to 23 knots. Festival! The floating speed increased from the original 12 knots to 16 knots!
Such a speed has reached the standards of many countries’ main battle nuclear-powered submarines!
In the test dock, Li Fanyu and Xing Yaxin stood on the observation embankment with their hands behind their hands, watching the ground staff who were as busy as little ants setting up the equipment required for the test.
"Director Li, it depends on today!" Xing Yaxin said with emotion.
Li Fanyu smiled slightly, "Yes. In terms of power, we have improved the three submarines to the extreme. But for the current sea environment, power is secondary. It is a mule or a horse, and it must be pulled out. . Whether we can let the three submarines pass through the sea depends on today."
"Report!"
While the two were staring at the submarine in the test dock, a correspondent ran up to them and saluted.
"Speak!" Xing Yaxin returned the greeting.
"Test preparations have been completed, please give instructions from the head!"
"Simulate the seabed environment, turn the sonar detection sensitivity to the maximum, and start testing!" Xing Yaxin almost shouted as he ordered.
"Yes!" The correspondent took the order, turned around and ran to deliver the order.
With a while of busy work below, the test officially began.
The huge simulated dock creates an audio environment that is the same as the seabed. In the dock, the submarine fixed on the test stand slowly turned on its power...
The ticking sonar sound, like a ghost lamenting, also appeared on the detector in front of Li Fanyu and Xing Yaxin.
……
Five and a half hours later.
Seeing the complete data appearing on the tester, Xing Yaxin could no longer restrain himself.
He touched the corners of his eyes and grabbed Li Fanyu's hands with force; "Director Li, I represent myself, the 920524 Submarine Research Institute, and the South China Sea Fleet. Thank you!"
Just when Li Fanyu was overwhelmed by his solemnity, the correspondent strode over again.
"Chief! An order came from the fleet and it was detected that a large number of ships from other countries were gathering for military exercises in the international waters near Apo Island! In order to avoid unnecessary losses, the fleet ordered us to withdraw the ships undergoing testing in nearby waters! ”
Xing Yaxin, with tears in his eyes, was stunned for a moment, and then his eyes widened angrily: "Why withdraw it?"
He casually took the mobile hard drive containing the test data of the three submarines from the tester and stuffed it into the hands of the correspondent, "Go, hand this information to the fleet command! Lock our 920524 Research Institute, three ships The submarine that has just been renovated is requested to go to international waters for testing immediately! ”
"Chief...today?"
Hearing this order, the correspondent holding the hard drive was in a daze.
Looking at the three submarines that had completed the test, Xing Yaxin's cheeks twitched for a while.
Scenes from the HH incident twenty years ago, and scenes from more than two months ago, flashed through his mind like a silent movie.
In his eyes, there was the same anger as more than 20 years ago, and he spoke every word;
"Yes, today!"
