Chapter 38 Come and beg me

“You think it’s really strange that the French Rattlesnake, with its small size, can actually travel more than ten kilometers, but our missile becomes so bloated when it is stuffed into the launcher?”

At this time, Qin Tao had just picked up a peanut with his chopsticks. Hearing this, he couldn't help but start shaking his hands again. The peanuts fell onto the plate and the chopsticks made a snapping sound.

The three men and one woman next to them looked ugly. Is this person laughing at us again? Some people even wanted to stand up, but Qin Tao quickly controlled his emotions: "The missile is stuffed into the launch tube, and the wings need to be folded, so that the size can be greatly reduced."

The size of the missile itself is actually not large. The diameter of the Hongqi-61 is only about half a meter. However, there are huge wings on the outside of the missile body, especially the four triangular wings at the tail. The area is not small. Only in this way can it provide sufficient steering torque, which also expands its diameter to more than one meter, making the outer launch tube so huge.

 Hence, the simplest way to reduce the size is to fold the wings.

At this time, after hearing Qin Tao's words, the girl among them spoke.

"Of course we know about folding the wings, but it is not easy to fold the wings. Whether it is pneumatic, hydraulic or electric, additional components need to be added. Our missile body has been developed. If we want to If such devices continue to be added to the missile body, more costs will have to be paid.”

"Xiao Ling, what's the use of telling him this? He doesn't understand." A man said: "They can only talk nonsense. Maybe they will ask us why we don't develop a vertical launcher similar to the MK41. Put all our missiles into it. How does he know the specific technical problems involved?"

What Qin Tao is wearing is not a military uniform, but a work clothes made of labor cloth. It is very reminiscent of a worker in a factory. He also likes to read newspapers and magazines. He thinks that he is very knowledgeable and can give advice. , in fact, it’s just amateurs making random comments.

"Pneumatic requires adding an additional air source inside the missile, hydraulic requires adding a special hydraulic pump, which will increase the size and weight of the missile, and electric requires consuming a lot of power inside the missile, so these are not suitable." Qin Tao ignored the man and just said to himself: "There are obviously simpler and more effective ways to solve the problem, but if you don't think about it, you always tie yourself up with complicated problems and tie yourself up. What a pity, what a pity!"

“Come on, scrambled eggs with tomatoes.” Pang Jianmin came over with the first plate of fried vegetables: “Qin Gong, come on, eat!”

“Okay, thank you.” Qin Tao picked up a piece of egg, put it in his mouth, and chewed it: “Not bad, not bad!”

The girl named Xiaoling put down her chopsticks, looked at Qin Tao with her big bright eyes, her lips trembled slightly, and then she said, "Excuse me, is there any other simple way?"

 “Xiao Ling, don’t ask him, this kind of person is just being mysterious.”

Qin Tao glanced at the guy, then shook his head: "Oh, some people, they are incompetent, and they still prevent others from asking for advice humbly."

"you!"

“Brother, please stop talking.” Xiaoling stood up, faced Qin Tao, and said solemnly: “Teacher, I humbly ask you for advice on folding the wings.”

“Don’t be so grand. It seems like I’m very arrogant. I’m actually very talkative.” Qin Tao said, “Take your stool, come sit down, and eat with us. I’ll introduce you to you.”

“Xiao Ling, don’t listen to him. It’s not like we haven’t considered it. Pneumatic, hydraulic, and electric are not suitable. The easiest way is to expand the size of the launch tube..."

Xiaoling has already moved the stool over.

Qin Tao glanced at it and saw that this technician was about the same age as herself. She also called the men as seniors. He should have just graduated from college.

She has an oval face wrapped in short hair, big eyes, long eyelashes, willow eyebrows, a delicate and small nose and mouth. She looks like someone who has just entered the society, but there is a slight trace of something in her eyes. Bloodshot, looks like he has stayed up late working on a scientific research project recently.

"Let me meet you. My name is Qin Tao. I graduated from the Institute of Shipbuilding Industry. What about you?"

“My name is Zhao Ling, you can also call me Xiaoling. By the way, the issue of folding the wings you just mentioned..."

Qin Tao held the two ends of the chopsticks with both hands, and then twisted them hard. The chopsticks instantly became a twist in his hands.

 “You can call me Taozi.”

Qin Baoshan was a little embarrassed there, little bastard, what are you doing? A few years ago, this would have been suspected of molesting lesbians.

Pang Jianmin went to pick up the second plate of stir-fried vegetables. Zhang Zhen stared at the chopsticks in Qin Tao's hand, his eyes twinkling.

 “Torsion bar?” Zhao Ling reacted.

"That's right, it's a torsion bar." Qin Tao said: "Many problems have simple solutions. In addition to using complicated external power methods to fold the wings, you can also add a simple The torsion bar serves as a torsional elastic component. When the missile is inserted into the launch tube, the torsion bar converts the binding force of the launch tube into torsional elastic potential energy and stores it in the torsion bar. When the missile flies away from the launch tube or launcher, the elastic potential energy is released. , so that the missile wings can be deployed automatically, especially for our surface-to-air missiles. The projectile exit speed is small, and the aerodynamic resistance suffered by the folded missile wings during the deployment process after the missile flies out of the tube is small, so as long as A simple torsion bar is enough to ensure that the wings are deployed within the specified time. In this way, the diameter of the launch tube can be reduced by half."

 The three men were stunned.

Of course they know that folding the wings can reduce the size of the missile launcher, and they have tried it. However, all methods are ineffective, so they have to create this large cylinder.

Now, Qin Tao came up with a simple idea: an elastic torsion bar, which adds very little weight to the projectile body, but can easily solve the problem!

“So, how should this torsion bar be arranged specifically?” Zhao Ling continued to ask.

“This is also very simple. I will draw you a structural diagram. There is no pen and paper here, so I will use water on the table..."

"I have it here." Zhao Ling had already taken out the notebook and pencil she carried with her and opened a blank page.

So, Qin Tao took a pencil and started drawing.

 A single-piece elastic wing with a torsion bar added at the wing root. Although Qin Tao did not use a ruler, it was horizontally and vertically drawn. Even the circles were drawn very standard, showing his excellent painting skills.

Qin Tao continued to say while drawing: "Actually, even if the wings do not fold, there are ways. For example, the cross section of the launch tube should be made square, the wings should be distributed on the diagonal, and the wing tips should be cut off. Part of it, in this way, the six-unit launcher can be turned into an eight-unit launcher."
