The strongest rocket soldier

Chapter 956

"What's the matter? What's the matter?" Erniang put down the bamboo basket in her hand and came to pick up Ding Xiaojun's daughter.

"Er Niang, I took my daughter out to play for a long time. When I came home, I didn't cook our meals. Before I said anything, my dad gave me five yuan to buy instant noodles." Ding Xiaojun said, putting The lollipop in his daughter's hand was forcefully stuffed into her mouth. In the past half a day, he has mentioned it. How cheating his daughter is, he intends to use candy to plug her mouth first.

"Your dad is really, how can you not let the child eat, you wait, I will cook for you." After Erniang finished speaking, she wiped her hands and went to the kitchen.

Ding Xiaojun looked at his daughter again and said, "Aren't you going to play with Feifei? Go."

……

When Ding Xiaojun took his daughter home, it was almost dark, and the two of them didn't come back until after dinner.

"Go back, you have to tell your mother..." At the gate, Ding Xiaojun coaxed his daughter, and he just finished teaching her what to say, and when he opened the door, he saw his daughter-in-law standing at the door.

Ding Xiaojun was stunned on the spot. He was wondering how much his wife had heard what he had just taught his daughter.

"Are you two good at playing? Could it be that it's not dark, you don't go home, and you teach your daughter..." Wang Yan stared at Ding Xiaojun and said.

"Isn't that afraid of making you angry?" Ding Xiaojun said with a smile on his face.

"I'm already angry, Yingying, I want to talk to your father when you go back." After Wang Yan sent her daughter away, she hooked Ding Xiaojun: "Come with me."

Wang Yan led Ding Xiaojun to open the utility room at home, and Ding Xiaojun found all the parts of the plane he built back then.

Looking at it now, those parts are so crude, but back then, it was too bold for me to dare to use these things to configure the aircraft.

"Look, can you still build your plane? To be honest." Wang Yan stared at Ding Xiaojun and said.

Ding Xiaojun walked over, flipped through it casually, and said, "It's a bit difficult, because the thinking back then was too naive."

"It's difficult, that is, it can still be done, so you can start doing it tomorrow, don't worry, this time, I won't starve you." After Wang Yan finished speaking, she walked towards Wai Nai, and Ding Xiaojun was missing. Left, but stayed, looking at the very outdated engine.

The early engines were all low-torque single-cylinder engines. If we talk about the explosive power at the beginning, it was very strong. Even if the speed could reach more than 7500 rpm, it was still far from enough as a power source for aircraft.

This requires him to find a way to increase the speed. Of course, there is another way, which is to increase the turning surface of the fan blades, but if it is necessary to increase the fan blades, with his 90cc engine, the fan blades are too big. I can't move it.

Ding Xiaojun is not the same as he was in the early years. Now he has gone through the technical training of the army and has a basic understanding of many power-related things. He is also fortunate that he was assigned to the Rocket Army and has been exposed to missile flying. Knowledge, which is very helpful for him to do things like airplanes.

Maybe some people don’t see it that way. Rocket engine, isn’t it a high-pressure jet engine?

Those who can think this way, it means that you know enough about the relevant power knowledge, but you have indeed overlooked a problem, that is, the balance problem. How can a plane go to the sky without balance, especially a helicopter-type plane, without balance? Without the balance system, what is built is just a shelf that can be raised and lowered.

For the balance of the aircraft, you can learn from the gyroscope system launched by the missile rocket to control its balance. Although it is impossible for Ding Xiaojun to create a precision gyroscope used on the missile, he knows the principle of the system and made a simplified version. Yes, it is still possible.

As for the power, he thought of the cvt transmission principle used in the car. As for the multi-link, it seems that the possibility of relying on manual work is too small.

Can it be made, there are too many things to be changed, at least the things that Ding Xiaojun made before, he is going to replace all of them, because it is too crude, let alone whether it can fly , I'm lucky if it doesn't fall apart.

Ding Xiaojun has already thought about the skeleton. Although he has never seen what a real helicopter skeleton looks like, he can make the kind of airplane he imagined according to his past thoughts and ideas.

Ding Xiaojun used both hands to move the engine outside. As a motorcycle engine with only over 20 kilograms, its weight can be easily moved.

Gasoline, this family has it. There is a three-wheeled motorcycle at home. It should be used as a farm vehicle by Ding Xiaojun during these years in the army. He needs to pump some gasoline from the tricycle first to see if the engine can work. use.

This oil pumping is not a technical job, as long as you find the corresponding oil drain pipe, it will be fine, but Ding Xiaojun doesn't know that this has been changed to a tricycle engine with electronic fuel injection, and that one is the oil drain pipe.

And Xiang didn't bother to dial the oil pipe directly connected to the fuel tank, because the current electric fuel injection engine is too delicate compared to the carburetor engine in the past. If there is a problem, it is not something he can fix.

Oil pumping requires some skills. Ding Xiaojun still remembers that when he was in school, he did oil pumping. He did this at that time. He found a long pipe and put it from the fuel tank mouth to the fuel tank. Then from the other end, which is lower than the fuel tank, use your mouth to suck, you can only see that the oil is almost reaching the mouth, let go of the oil pipe, and the oil will naturally go out along the way.

This method may be the most simple and direct, but it also tests people's ability to respond. If it is not in place, it will suck a mouthful of oil. In the past, Ding Xiaojun often drank gasoline because of this.

Ding Xiaojun doesn’t plan to use the old method anymore. He knows another method. This method is something he learned from a veteran of the army. The veteran is from the maintenance station of the army. matter.

Ding Xiaojun got up and went back to the utility room. He remembered that he found the tube he had used in it before. However, the tube was too thin, and it was as thick as the metal tip of the refill of a ballpoint pen. It's not bad, this is at home, not in the army, and it's not bad to have a pipe.

Ding Xiaojun found the thin tube, looked at it, and muttered, "This is not as good as an infusion tube, it's too thin."
