"Turbo steam engine?" Ling Meimei looked left and right with the parchment, as if she understood it.

Si Lunlun stretched out his head and looked at it for a long time, and suddenly said, "I understand a little, is it like a waterwheel mill or something like a watermill?

"That's right!" Xu Zheng said with a smile: "It's just that the water is replaced with steam here, and the steam that turns after the water boils has more power." After pressurization in a confined space, it is enough to push the turbine in front of it to rotate at high speed, thereby driving the propeller to rotate and then drive the aircraft to fly. ”

Sankike was surprised and delighted: "So, my brother's plan is completely feasible?"

Xu Zheng nodded and shook his head, and said: "The design method is correct, the thinking is also correct, with the existing technical level, this is the highest level of engine that can be built at present." But your brother's design was too idealistic and didn't take into account many practical technical problems and applications. For example, the condensation recovery of steam after driving the turbine, the treatment of exhaust steam, the incorrect structure of the turbine, the injection problem of the steam chamber, etc. When these problems all come together, it becomes a big problem, enough to make the design waste. ”

Sankike said dejectedly: "That means that it doesn't work at all. ”

Xu Zheng was happy and said: "I didn't say no, I just said that it still needs to be improved." ”

Sankike said discouragedly, "You can finish it." Remember to put a few of them on our planes. ”

Xu Zheng shook his head: "No, I plan to wait for your brother to come to some research." ”

"What?" The three little ones all turned their heads to look at Xu Zheng. Lingmei asked tentatively, "You don't mind?"

Xu Zheng smiled: "I don't mind. To be honest, Sanduodo can think of this, he is actually better than me. Not only is he good at using the existing level of technology to create, but he can come up with this, which is already a very remarkable breakthrough!" It doesn't always work. And Sanduoduo thought about it, and he could only say that this little dwarf was quite remarkable.

Honestly looked at Sankik. Said: "Your brother is really powerful, I can't plagiarize his research results, why don't you ask him to fly over, how about everyone study this together? Maybe your brother can make a splash with this and impress the people in the dwarf tribe." From now on, everyone will no longer look down on him. ”

Sankirk was in ecstasy, and exclaimed, "I'll fly to pick him up! My brother must be glad to hear that someone praises him so much! Wait for me, and I'll be back soon." ”

Leaving Xu Zheng and the two gnomes to continue to study Sang Duoduo's parchment scroll, Ling Meimei looked at Xu Zheng with a smile and said, "You are really different from those humans, a little like us gnomes. We will never take advantage of the research results of others. I've heard old people say that most humans seem to have too much selfishness. ”

"Awards, awards!" Xu Zheng laughed and said, "Actually, I understand." People like you who have hobbies. One mind is nothing more than wanting to make something better, to make everyone's life more interesting and better. You may love to dream. Acting strangely, but at the same time it means that you have a purer heart. I can't bear or dare to defile such a beautiful soul, I just want to take good care of it. ”

Schlenlun was stunned and asked, "Are gnomes so good? Think we're just a race that doesn't know anything but make weird things. Well. Probably in the eyes of most human beings, we are crazy people, freaks or something. ”

Xu Zheng laughed and said, "Do you care what others think?"

Si Lunlun nodded and said, "A lot of the time, I still care a lot. In fact, the dwarves also want to get out of the dwarf island, live in the world equally with all races, and use our technology to make the world a better place. ”

Xu Zheng squatted down, looked at Si Lunlun's eyes, and said slowly: "Please believe me, as long as you stick to such a wish, you will definitely be able to achieve it." Gnomes are actually a remarkable race. Chong Slunlun squeezed his eyes and smiled, "Height is not a problem. You're so short!"

The first time she heard someone praise a dwarf like this, Ling Meimei laughed and said, "Xu Zheng, I like you." You have changed my perception of human beings. Hehe, thanks to the fact that the plane fell that day. Well, I'll tell you about your existence in the future, and there is such an interesting and talented technician among the human race. ”

"Thank you. Xu Zheng smiled: "If you have the chance, you can go to Dwarf Island to have a look, are you welcome?"

"A clever technician is coming to Dwarf Island?" said Slenlun, "Oh, of course welcome! Didn't you just say that height is not an issue? A human like you, I can only say, race is not an issue! The patriarchs and elders should be happy to see you." Provided, of course, that you don't fight the idea of a dwarf self-defense weapon. ”

Xu Zheng said: "I'm not interested in that. ”

The two dwarfs laughed and said, "That's good, we'll report to the patriarch when we go back this time." To be honest, we are also tired of sneaking materials and food. ”

Thinking of the appearance of a little smuggler, Xu Zheng couldn't stop laughing. The three of them laughed as they continued to look at the drawings, and two hours later heard Sankirk's plane land, and then rushed in with a dwarf about his height.

The dwarf named Sandodo rushed in and shouted, "Which human is the one who understands my blueprint?"

Xu Zheng pointed to his nose: "Me." ”

Sang Duoduo moved his little short legs, ran to Xu Zheng, looked up, and said with a suspicious expression: "You, a stupid human being, can understand my things?"

Forehead...... Very conceited and stinky little fart. Xu Zheng straightened up and lowered his head to look at him.

Xu Zheng's height is only average among humans, but Sang Duoduo is not as tall as his waist. Like the previous three, this little Bu'er also had ridiculously large eyes, soft brown hair, and the contours of his face were similar to those of Sankike and Qichi and Eight. Otherwise, Sandodo has large eyes that appear more spiritual, and his ten fingers are more slender, making him seem to be more scribbling than touching parts. The three small clothes were all covered in oil, but Sandodo's looked very clean, reminiscent of a nerd who spent all his days immersed in experiments and ignored reality.

Now, he is looking up at Xu Zheng with his hands down, and his face is not a domineering and annoying expression, but a look of sluggishness and stubbornness that can only be cultivated in a laboratory that is seriously out of touch with reality, like saying that as long as Xu Zheng can't say anything, he will jump up and compete with you, and use a lot of theoretical data to knock you down.

Having come to this conclusion, Xu Zheng already had a plan in his heart on how to deal with him, so he asked with a smile: "Sanduoduo?"

Sandodo nodded and said, "Keke said that you think what I designed is useful and not, isn't that true?"

Xu Zheng nodded.

Sandodo said, "Please say, use your reasoning to refute me." ”

Sankike was embarrassed and said, "My brother is ...... Belch...... It's a little ......" pointed to his head, and bent his middle finger to knock again.

Xu Zheng laughed, this action that indicates the teasing of the head seems to be universal to all time and space.

Stretching out his hand to flick the parchment roll, Xu Zheng said, "Where did you get this inspiration?"

Sandodo said: "Boiling water in a pot will cause the steam to break the lid, which is the inspiration I got from here. ”

"That's good. Xu Zheng said: "Have you ever calculated how much water you need and how much fuel you have to use to boil water in order to smoothly push the turbine in front of you, so as to push the propeller to rotate?"

Sandodo hesitated. Xu Zheng smiled and said, "It's just speculation based on observation and conjecture, right?" Pointing to the pattern on the parchment scroll, he said, "Look, your design is to use steam to directly push the turbine, right?"

Sanduodo nodded: "This will reduce the loss." ”

Xu Zheng smiled and asked: "What does steam rely on to push the piston?"

"Pressure. Ling Meimei continued.

Xu Zheng stretched out the back of the turbine and said: "Look here, the steam acts directly here, if it is not pressurized, it is the original jet force of the steam, and this unprocessed force is not only small, but also unstable." The real use of it is to use its reaction force to push the turbine after pressurization, so a pressurization chamber and a regulator chamber must be added here. Stretching out his fingers, he casually drew a turbine on the ground with two attached structures according to Sandodo's blueprint, and the view drawing method that was more standardized than that of the gnome immediately impressed the four little ones.

Sang Duoduo looked at Xu Zheng and was already a little convinced, and said, "What about the blades, what's wrong with the wheel blades?"

Xu Zheng said: "Your original design was a large-angle four-bladed pulp wheel. This is very inefficient, and most of the energy will be lost. If it is a medium with high resistance, such as water, it is suitable. Here is steam, and blades of this shape are not suitable. And with this design. Xu Zheng drew a multi-blade duplex small-angle embedded structure on the ground, and said with a smile: "This kind of blade has a higher utilization rate, and it is not easy to break, and the rotation speed is also higher." The disadvantage is that the structure is complex and the forging is more troublesome. It is estimated that it depends on the craftsmanship of the dwarves. ”

Hearing this, Sanduoduo was completely convinced. This is good for dwarfs, being persuaded is really persuasive, and they will not be entangled in their faces.

"I want to be part of this research!" said Sandodo.

"Really, brother, are you serious?" Sankike was overjoyed, Sanduoduo had never been moved by any of the research groups before, but this time he actually took the initiative to ask to join, which shows that he was really moved. At the moment, she looked at Ling Meimei with begging eyes. "Meimei ......"

"No problem!" said the big-eyed dwarf sister heartily.

Schlenlun laughed happily and shouted, "The four-person research team has been officially formed! Let's go to the position of senior technician together!"

"I still have to take the beginner ...... exam Actually, I don't really care about that. Sandodo said.

"Let's take the test, brother. Let's study it together, how interesting it is!"

Sandodo hesitated for a moment, then nodded. The three cheered again.

Xu Zheng watched from the side and couldn't stop laughing. Gnomes, it's really interesting.
