Liuyun glanced at the "Spey MK202" engine that was about to be fixed on the test bench, and then looked back at Liu Xuanying: "Yes, I can eliminate the wrong data I gave you." ”

Liu Xuanying popped up a black line: "Dad, John Niu has started the turbine engine plan, time is pressing, can't you give a ready-made answer?" ”

Liuyun shook his head: "Don't worry, haven't you noticed that the gas temperature before the turbine and the speed of the high-pressure compressor determine the thermal efficiency of the engine?" ”

"That's the case," Liu Xuanying nodded, "But, can't they find out?" ”

"It's one thing to find out, it's another thing to make it happen." Liuyun laughed and looked at the engine on the test bench, "Didn't you find that you have never encountered a threshold in the selection of materials during the simulation test?" ”

Seeing Liu Xuanying stunned there, Liuyun sighed, he stored a large amount of materials science information in the database of the base: from the properties of materials, to the development route of materials, to the smelting and processing technology of materials; Even rabbits have always been greedy, and the industrial process of carbon fiber of various specifications that has not been "written" by "writing wheels" is readily available......

No one will know how valuable the materials stored in the Dawn repository will be.

It is no exaggeration to say that in terms of materials, you can take out a curve chart at will, take it to a foreign country, find someone who knows the goods, and you can buy tens or even millions of dollars at will: because the data on the curve can allow the relevant materials research institute to save more money and time.

With the materials and processes, the rest is the production technology.

In order to win at the starting line, Liuyun will develop some material processing technologies in a forward-looking manner, such as laser processing, plasma spraying, nickel-based single crystal casting, etc.

And some of the materials research institutes under Liu Xuanhui occasionally receive special tasks from Liuyun: to industrialize the industrial production of some alloys in the database that are not in high demand but have excellent high-temperature mechanical properties.

Liu Xuanying would not have imagined that the materials that "can be used casually" in her mouth are now in the laboratories of European and American powers, and they are also unavoidable.

With chickens, it's a matter of eggs.

I have always liked to step on the flowing clouds of others to cross the river, and directly copied Eagle Sauce's "Advanced Turbine Engine Gas Generator Plan".

The key to this plan is to take the core parts of the turbofan engine: the compressor, the combustion chamber and the turbine as a whole - the "core engine", and then through continuous testing to determine the optimal combination of the various parts of the "core engine" under various thrust requirements.

Later, the engines of Eagle Sauce's various fighters and bombers were basically based on this "Advanced Turbine Engine Gas Generator Program".

As a result, the "Advanced Turbine Engine Gas Generator Program" became the task of "core engine serialization", which fell to Liu Xuanying.

Liu Xuanying shook his hand and assigned the task to the aero engine institute, in order to comfort the hearts of many friends of the engine institute, the aviation engine institute also had a code name 302 before the "Spey MK202" was finalized.

After waiting for the friends of the 302 Institute to be happy for a few days, the Aircraft Shape Research Institute next door not only had the code name 303, but also took into the arms of an experimental base in Jiuquan with the latest supersonic wind tunnel.

The 303 Institute, which had just received the code name, unsurprisingly received the relevant task of the new fighter: to optimize the aerodynamic shape of the fighter codenamed "JF-17" to match the "Spey MK202".

In order to "pull Lang strong matching", 304 institutes responsible for body design and control systems were established in the northwest; The avionics system is ...... by Computer 1021

Later, the institute in charge of communications and radar technology also had a code name......

Looking at the series of research institute code names surrounding JF-17, the high-spirited Liu Xuanying wilted again......

Just when Liuyun happily watched the dragon gradually take shape, Liu Xuangong sent a telegram to ruin Liuyun's good mood: Okamura Ningji, the successor of the former commander of the Japanese North China Front, Tada Jun, proposed an ember annihilation strategy.

I thought that after nearly four divisions were lost in Jinlingtu, the Japanese army would be honest, but Liuyun did not expect that when the troops were stretched, the ember operation, that is, the "three-light policy", would still appear in the tactics of the Japanese army.

Liuyun gritted his teeth, grabbed a pen and wrote a note, and handed it to Liu Xuanzhi: "We won't do anything that is punished without teaching; However, if you knowingly commit a crime, then you need to be punished by a canonical punishment. ”

In April 1942, just as the Japanese army was preparing to carry out the "law and order enhancement" campaign, American newspapers published a statement from the "Yanhuang Restoration Society": blood for blood, tooth for tooth.

One day in mid-May 1942, Liu Xuanying, who had returned to his residence after a busy day, received a call from his eldest sister Liu Xuanling: his old man, his follower Lao Qi, was gone......

At first, Liu Xuanying thought that her eldest sister was just joking with herself, but when she wanted to eat, Liu Xuanying realized that her old man was really, really lost.

As a result, chickens and dogs jumped in the Jiuquan Industrial Base, and the next day, several other sisters in the field rushed to Jiuquan.

Under the bewitchment of several sisters, Liu Xuanzhi searched his old man's room, and found a telegram on his old man's desk: The 36th Division is suspected of having special forces.

Looking at the telegram that returned to his hand, Liu Xuanzhi wanted to cry without tears: The sisters in the family, I don't know how to clean up after myself!

Sure enough, when he saw the first telegram in Liu Xuanzhi's hand, Liu Xuanqi slashed his head and covered his face: "Xiaozhi, you are a full man who doesn't know that a hungry man is hungry, you have a daughter-in-law, so you let go of the only two meal tickets in our family." ”

Liu Xuanqi, an older leftover girl, coaxed beside her: "That's it!" It is! ”

What the hell is this!

"Sixth, is your gene editing project complete?"

Liu Xuanqi's heart was poured cold by Liu Xuanxin's words.

"Second sister, do you think our father dislikes me?" Liu Xuanqi looked depressed, "Why does my research institute have to be in a remote desert?" ”

"Sixth, you are cheap and good-natured, our father will go to see you when he is not free."

"Fifth sister, you still say me, aren't you the same?"

Liu Xuanling was a little impatient and knocked on the table: "I said a few of you, can you stop?" Now it's time to discuss where our dad went? Also, they're all adults, so you don't have to pester our dad every day, right? ”

"Oh."

Liu Xuanling glanced at Liu Xuanshu and Liu Xuanqi: "Two vinegar jars, isn't it just because our father didn't take you two when he went out to play!" ”

"Eldest sister, this is not going out to play." Liu Xuanzhi raised his hand in fear, and then handed over the telegram.

Liu Xuanling dusted off the telegram: "See, I won't take you, because your combat effectiveness is too scummy!" ”

"Cut!"
