Jiang Xiaofei can't help too much, after all, he can't strike iron and can't do anything else, so he can only stand by and try to guide.

"Jiang Gongzi, just look at it, we will definitely make this helicopter for you. ”

"yes,"

"Then it's hard for everyone," Jiang Xiaofei also hurriedly replied.

"Misfortune, misfortune, let's all not be idle, let's start quickly. One of them shouted.

"yes, let's hurry. ”

I saw that several people divided their labor and did their own work, Jiang Xiaofei stood on the stage and saw the huge iron material piled up there, and he was quite looking forward to it.

"Brother-in-law, can this really make a helicopter?" Su Muhe was also a little skeptical, a pile of scrap iron can fly into the sky? Those treasure flying swords are all made of good legendary materials, and flying in the sky also requires immortal cultivators, and Su Muhe also learned that anyone can fly this helicopter, which is completely incredible.

Jiang Xiaofei shook his head unexpectedly, "I'm afraid not." ”

"What? can't you, brother-in-law?" Su Muhe was also stunned when he heard this, didn't he deceive the people of Water City?

Jiang Xiaofei looked around and was busy in full swing, "What do you say? The most important thing about this helicopter is not the shell, but the core. ”

"Core part?" Su Muhe was also stunned, "What core part?"

Jiang Xiaofei looked at the distance and saw a few people faintly coming, and his face was happy, "It's coming,"

Su Muhe's face was puzzled, and he looked over and saw that it was a few people from the Sanniang faction, "They?"

"That's right, the core part is made by them," I saw the four people hurriedly pause and bow.

"Meet Jiang Gongzi, we are the four brothers of the Shi family, just call us Shi Dashi, two stones, three stones, and four stones. Then he saw the swarthy old man in the middle who was in his fifties and said.

Jiang Xiaofei saw a few people and instantly sensed the aura of the four of them, all of them were in the Jindan period, and the aura was also very strong, "Seniors, I really have to trouble a few seniors next." ”

"Harm, you kid, don't you know that my Shi family, that is the No. 1 forging family in the Xueling world!" The youngest of them was swarthy and fierce with the anger just now.

"Fourth, Hugh is rude. Shi Da hurriedly reprimanded, and saw Shi Si slowly shut up, "Hehe, Jiang Gongzi is sorry, but what my fourth brother said is also right, my Shi family can also be regarded as the number one forging family in the world, and there is really nothing that we can't forge." Shi Da naturally disagreed with Jiang Xiaofei's words, but he also had some understanding of Jiang Xiaofei's identity, and this time he was invited by Duobao Pavilion, so he had to give Duobao Pavilion some affection.

"I also asked Jiang Gongzi to take out the sketches, and we will look at them one or two. It's good to make it as soon as possible. ”

Jiang Xiaofei took a look, heh, these people are really a little proud, of course, Jiang Xiaofei has not heard of the name of this so-called first forging family, but the current situation is not easy to make a moth, "Please also ask the seniors to take a look." He hurriedly gave the sketch in his hand to the man, and left.

Of course, Jiang Xiaofei didn't see the next scene, only to see the four people gathered there, at first there was nothing strange at a glance, but the more the four of them looked at it, the more strange it became, and the more they looked at it, the more shocked they became, and they couldn't help but quarrel.

The sketches for the four of them are about engines and electric motors, of course, Jiang Xiaofei, as a liberal arts student, can only understand some general things, and it is impossible to completely draw all the things for them, so they can only ponder it.

Jiang Xiaofei ignored them and let them discuss it by themselves, and the second most important thing next was the propeller, the helicopter not only needed to raise the propeller but also adjusted the propeller.

I saw that those who only needed the propeller were carefully polishing the propeller.

"Big brother, do you think these things can really go to heaven?"

"Hey, who knows, the heavens are all the abilities of immortals, where can we mortals go to the heavens?"

"It's not, but this Jiang Gongzi promises to go to the sky, it seems that it is really possible, after all, this helicopter was built to save our Water City,"

"Alright, don't complain, hurry up. ”

Before Jiang Xiaofei arrived, he listened to these people's suspicious faces, and when he heard it, he was quite emotional, once the earth was like this, how could human beings go to heaven? Later, he went to heaven, and how could he have landed on the moon? Later, he also landed on the moon.

"Jiang Gongzi. Hehe. Jiang Xiaofei deliberately put down his steps, and suddenly the few people who made the propeller put down the objects in their hands and shouted.

Jiang Xiaofei politely saluted, "Hehe, hard work, I hope you can complete it as soon as possible, the workmanship must be fine!"

"Harm, Jiang Gongzi, look at it, we are the female celebrities among the blacksmiths,"

"Haha. ”

Jiang Xiaofei also smiled knowingly, seeing that these propellers also had a rough outline, at this speed, I am afraid that it will be almost made in another two or three hours.

At this time, the helicopter rack next to it also gradually had a rough outline, and a big guy with a big front and a big back was also gradually completed, seeing that everyone was busy, Jiang Xiaofei was also suddenly full of confidence.

"Hey, Jiang Gongzi, you can't do this engine, how can you do it with the motor?" At this time, the four members of the Shi family came to Jiang Xiaofei arguing.

Jiang Xiaofei also smiled in his heart, naturally knowing that it was impossible for the four of them to completely manufacture these two things, which was made by the earth for many years, but now that he has his own general theory, as well as the four members of the Shi family who claim to be the first, as well as the resources of Water City, presumably this core part should be able to be manufactured.

"Senior, why don't we go and talk?" Jiang Xiaofei hurriedly asked.

The four members of the Shi family did not completely eliminate their dislike for Jiang Xiaofei, and agreed that this was impossible for the young man in front of them to know, but after this drawing, although they didn't believe it, they were attracted.

I saw the five people slowly coming to the side, and there happened to be a stone table and stone bench there.

"Senpai, please. ”

"Don't be so polite, boy, hurry up and say what is on this drawing,"

"Fourth!"

"Jiang Gongzi, my fourth brother has such a violent temper, and we are all stumped by the things on this drawing, that's why it's like this. ”

Jiang Xiaofei smiled, "It's nothing, now that the situation is in crisis, I also know that this mission is important, so senior, let's talk about it in detail." ”

So the four of them stopped talking and quietly listened to Jiang Xiaofei's preaching.

The principle of the engine included in this drawing is: the huge iron lump mixes air and fuel in a certain proportion, is sucked into the cylinder in the suction stroke, the mixture is compressed and ignited to produce heat energy, the high temperature and high pressure gas acts on the top of the piston, pushes the piston to reciprocate linear motion, and outputs mechanical energy through the connecting rod and crankshaft flywheel mechanism.

"That Jiang Gongzi, what is thermal energy? What is a piston? There are connecting rods, crankshaft flywheels, and mechanical energy, these are all strange names?"

Jiang Xiaofei was also stunned, yes, this is not the earth, so naturally he doesn't know these terms, and then Jiang Xiaofei explained these terms in general.

The four members of the Shi family looked confused, but they had a sudden feeling, "It seems that Jiang Gongzi has some opinions about forging." ”

Jiang Xiaofei smiled, that's for sure, but he knows it on the earth, "Senior, I'll continue to talk about it." ”

The four of them nodded hurriedly.

The engine is composed of two major mechanisms, the crank connecting rod mechanism and the valve mechanism, as well as five major systems: cooling, lubrication, ignition, fuel supply, and starting system. The main components are cylinder block, cylinder head, piston, piston pin, connecting rod, crankshaft, flywheel, etc. The working chamber of a reciprocating piston internal combustion engine is called a cylinder, and the inner surface of the cylinder is cylindrical. The piston that makes reciprocating motion in the cylinder is hinged with one end of the connecting rod through the piston pin, and the other end of the connecting rod is connected with the crankshaft, and the crankshaft is supported by the bearing on the cylinder block, which can rotate in the bearing to form a crank connecting rod mechanism. When the piston reciprocates in the cylinder, the connecting rod drives the crankshaft to rotate.

Jiang Xiaofei saw that the four of them were confused for a while, and they also understood the meaning, and hurriedly explained the terms in it again, the four of them were also like geniuses, they understood it as soon as they heard it, which also shocked Jiang Xiaofei, it seems that the title of the first forging family is not fake.

When the crankshaft rotates, the connecting rod journal moves in a circular motion in the crankcase, and drives the piston to move up and down in the cylinder through the connecting rod. Every time the crankshaft rotates, the piston runs up and down once, and the volume of the cylinder is constantly changing from small to large, and then from large to small, and so on. The top end of the cylinder is closed with a cylinder head. The cylinder head is equipped with intake and exhaust valves. By opening and closing the intake and exhaust valves, the cylinder is filled and the cylinder is vented. The opening and closing of the intake and exhaust valves are driven by camshafts. Camshafts are driven by a crankshaft through toothed belts or gears.

The general engine is like this, but the manufacturing inside is a little troublesome.

This is also Jiang Xiaofei's request for immortal cultivators to make engines, after all, it is impossible for ordinary people to make them, and there is no earth machinery factory here to make engines manually.

After hearing this, the four of them couldn't help frowning, and slowly lowered their heads to look at the drawings and think about something carefully, Jiang Xiaofei no longer bothered when he saw this, but hurriedly stepped aside.

At this time, looking at the square again, he saw that a huge helicopter model was completely completed, Jiang Xiaofei was full of joy in his eyes, this was the last step away from the construction of the helicopter.

"I told you that this little propeller is in the back!"

"No, if it's in the back, it will affect the big propeller above. ”

“......”

Immediately, I saw a group of people next to the helicopter making noise, and I saw two old men with black faces and loose hair arguing.

When Jiang Xiaofei heard this, he was happy in his heart, but fortunately he knew some of the principles, and it seemed that it was another opportunity to pretend to be forced.

"Ahem. ”

"Jiang Gongzi is here, Jiang Gongzi must know. ”

Jiang Xiaofei coughed deliberately, and slowly paced to the helicopter, only to see that the helicopter at this time was also dyed with blue and white colors according to the requirements, and it had the feeling of an Air Force helicopter.
