Expedition to Europe

It is not too late for Lanfang to start researching jet engines from now on. In fact, from the perspective of the depth of understanding, Lanfang has already taken a certain advantage.

Because Maxime Guillaume is French, he obtained the patent for the first jet engine and can share it with Lanfang. This is part of the friendship between Lanfang and France. Although the alliance relationship has been dissolved, the cooperation at the technological level is closer because the French know very well that Lanfang will no longer share information with the French as in the past. If France still wants to enjoy the dividends brought by Lanfang's technological progress, then the French must be more enthusiastic.

As the "guide" of Lanfang Technology, Qin Zhiyuan must have given Long Chengyuan considerable help, so before Long Chengyuan came to his senses, Qin Zhiyuan dropped another bombshell: "The principle of jet engines is still the reaction of force. Compared with the current propeller engines, jet engines are a combination of engines and propellers. Both jet engines and propeller engines rely on pushing a large amount of gas backwards to obtain thrust, but propeller engines obtain thrust in the form of a large amount of air slipstream at a relatively low speed, while jet engines obtain thrust in the form of extremely high-speed gas jets. If you want to summarize the working process of jet engines, it is probably: intake, compression, combustion, exhaust."

"Intake, compression, combustion, exhaust--" Long Chengyuan was dumbfounded and subconsciously repeated Qin Zhiyuan's words.

As the director and chief researcher of the Lanfang Aero Engine Research Institute, Long Chengyuan is already a leader in the field of aero engines in this era, but people are limited by the times, and Long Chengyuan is the same.

The propeller engine has developed to this point, and there is still a certain potential to be explored, but the performance improvement is already quite limited. If the "thunder" proposed by Qin Zhiyuan can be realized, it will probably be the pinnacle of the propeller engine. There may be a few derivative models, but that's all.

Jet engines are different. This is a future development direction that has been verified by facts and has unlimited possibilities. Compared with propeller engines, this is equivalent to a new field and a new challenge for Long Chengyuan.

Such a challenge is undoubtedly very happy for Long Chengyuan.

"Then what do we need "thunder"? Let's develop jet engines directly. I have an idea, which may be very likely to be realized-" Long Chengyuan is a standard action person. Before he finished speaking, he had already entered the working state and was about to walk into the laboratory while muttering.

"Wait, wait-" Qin Zhiyuan grabbed Long Chengyuan.

"What? Don't delay my work! I already have an inspiration-" Long Chengyuan was furious, and immediately shook off Qin Zhiyuan's hand, roaring in his mouth and walking away without looking back.

Scientist!

That's it.

Qin Zhiyuan could only spread his hands helplessly. If he said a few more words and Long Chengyuan's inspiration was gone, it would be a waste of time.

As for those things that had not been said yet, they could only wait until the future.

As a result, this wait lasted until 1923.

Qin Zhiyuan saw Long Chengyuan again on February 8, 1923. This day was the Chinese lunar year of Renxu. In a few days, it would be New Year's Eve. All the agencies of Lan Fang, except for some special departments, had to take a holiday. Only then did Long Chengyuan leave the laboratory.

Misha gave Qin Zhiyuan a daughter a month ago. The birth of the little princess immediately made many people cheer. This not only represented the future stability of Lan Fang's political arena, but also meant that all Westerners in Lan Fang's scientific and technological circles had finally merged with the country of Lan Fang.

Misha's father Michelle and mother Sandy are both leaders in Lanfang's technology industry. Although Misha's marriage to Qin Zhiyuan represents a close union between the two parties, due to the tradition of the Chinese world, having children and not having children are two completely different things. These Westerners have lived in Lanfang for a long time and are very familiar with these Chinese customs.

Misha was quite uneasy about not giving birth to a son for Qin Zhiyuan. From the bottom of her heart, Misha hoped to have a daughter, but the meaning of a son in the Chinese world is extraordinary. Misha was very worried that Qin Zhiyuan would not like this little girl.

Qin Zhiyuan didn't feel that there was anything wrong with having a daughter. Although Qin De and Qin Zhi had grown up without Qin Zhiyuan having any worries, Qin De, the naughty guy, often made the palace a mess. Even Qin Zhi, who had just learned to speak, had a tendency to get close to Qin De, which made Qin Zhiyuan really hope that he would have a caring little cotton-padded jacket.

So even though the little guy couldn't see clearly and had no impression of Qin Zhiyuan as his father, Qin Zhiyuan still tried to take time to see the little guy every day, even if it delayed his work.

At the end of the year, there were indeed a lot of things to do, but many things didn't necessarily require Qin Zhiyuan to come forward. Lu Zhengxiang could also represent Qin Zhiyuan to a certain extent, and even replace Qin Zhiyuan to a large extent. At least Qin Zhiyuan couldn't sign for those units that wanted more budgets. Only Lu Zhengxiang had this right.

Of course, for the military, Qin Zhiyuan was absolutely irreplaceable. Lu Zhengxiang was not very useful in this regard. The Lanfang military only recognized Qin Zhiyuan, and everyone else had to stand aside.

When he met Long Chengyuan, Qin Zhiyuan was reading a document in the living room, and in the cradle beside him was Misha's daughter Xiaodoudou.

In terms of name, Long Chengyuan is Xiao Doudou's uncle, but Long Chengyuan is a bit incompetent. When Xiao Doudou was baptized, Long Chengyuan was doing experiments, and when Xiao Doudou was celebrating her full moon, Long Chengyuan was still doing experiments.

Compared with the last time I saw Long Chengyuan, Long Chengyuan is obviously thinner now, but his mental state is still good, and he is even a little excited, so when he saw Qin Zhiyuan, he spoke louder; "Your Majesty, I have completed the drawings of a jet engine, and now I can arrange for the production department to verify it. If everything goes well, this engine will have no problem pushing a four-ton aircraft to an altitude of 10,000 meters. In terms of performance, it can beat all fighters in other countries now, and one can beat ten -"

Long Chengyuan was a little too excited and didn't notice Xiao Doudou in the cradle. Qin Zhiyuan didn't ignore Xiao Doudou when he heard Long Chengyuan speak. Seeing that Xiao Doudou's brows just frowned, Qin Zhiyuan immediately made a "silence" gesture to Long Chengyuan.

"Uh uh - sorry, Your Highness the Princess -" Long Chengyuan still knew about Xiao Doudou's existence, and did not forget to send a meeting gift, a lush green jade Maitreya Buddha pendant.

Men wear Guanyin and women wear Buddha -

After the Lan Fang forces began to get involved in Siam, Qin Zhiyuan was most happy about jade, in addition to rice. Although the main production area of ​​jade is in Myanmar, it is really easy to get some rough materials from Myanmar because of the infiltration of the "autonomous" government of the ten provinces in northern Siam.

The original text is in Liu # 9 @shu/bar!

As for jade, Westerners do not think it is a gem. Westerners prefer diamonds, rubies, sapphires, etc., and do not classify jade as a gem. Only Orientals like jade. Therefore, the British are not very strict in controlling the rough jade materials. Basically, they can dig as much as they want.

Qin Zhiyuan likes jade very much, so Qin Zhiyuan's attitude towards jade rough materials is to take as much as he can. In his previous life, Qin Zhiyuan was short of money, and he could only look at those imperial green and glass jades. In this life, Qin Zhiyuan can finally play with them to his heart's content.

Xiao Doudou still doesn't quite understand what jade is. She curled her lips twice and finally fell asleep.

Then Long Chengyuan's voice was much smaller: "Your Majesty, we don't need to make any propeller fighters, just use jets. As long as our jets can be made, we can kill everyone immediately. As long as we have enough planes, no matter whether it is the United States or Britain, we will bomb them all and see what kind of planes they can take out to compete with us."

Long Chengyuan is still a little radical. Of course, this is also related to the consistent guiding ideology of the Lan Fang military. The slogan put forward by the Lan Fang military is "specially deal with all kinds of disobedience". As long as someone dares to challenge the majesty of the Lan Fang military, the Lan Fang military will let them understand why the flowers are so red.

"We need to have a plan for the development of our weapons. We need to equip one generation, design one generation, and conduct pre-research on one generation." Qin Zhiyuan made his suggestion straight to the point, causing Long Chengyuan to fall into a stagnation again: "Strictly speaking, the 'Falcon' we are currently equipped with is already invincible. Whether it is the United States, Britain or France, our 'Falcon' can be more than ten years ahead of them. However, we cannot rest on our laurels. We must have a sense of crisis. The Americans are still very capable in scientific research. If they realize that they are lagging behind, they will catch up in no time, so we must accumulate more technology. For example, if we have the blueprints for this jet engine now, that's great. We can save them first as our technical reserve. Our current 'Falcon' is already enough to scare the enemy. When our enemies come up with fighters that can compete with the 'Falcon', that's when the 'Thunder' will appear. As for more advanced fighters, they can only exist in the laboratory."

Equip one generation, design one generation, and conduct pre-research on one generation. This was once the scientific research requirement put forward by the Republic. This requirement fully demonstrates the Chinese people's principle of keeping a low profile, which is both forward-looking and confusing, and is extremely appropriate for military use.

"Then I have to make the 'Thunder'——" Long Chengyuan was a little depressed. He was obviously not allowed to research more advanced things, but he had to go back to the same place and continue to go around in circles. This would make no one willing.

"First make the 'Thunder'. As for this engine, don't worry, there will be a day when it will shine." Qin Zhiyuan promised Long Chengyuan that no matter whether it meets the requirements or not, the hard work of scientific researchers is worthy of respect.
