Warship of Great Power

  Chapter 38 Come and beg me

   "You say, it's really strange. The French Sea Rattlesnake, with such a small size, can hit more than ten kilometers. Our missiles become so bloated when they are stuffed into the launch tube?"

   At this time, Qin Tao's chopsticks had just picked up a peanut bean. Hearing this, he couldn't help shaking his hands again. The peanut beans fell on the plate, and the chopsticks made a crackling sound.

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

The volume of the missile itself is actually not large. The diameter of 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, and the outer launch tube is so huge.

  So, the easiest way to reduce the volume is to fold the wings.

   At this time, after hearing Qin Tao's words, one of the girls 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 give If the missile body continues to add such devices, it will cost more.”

"Xiao Ling, what's the use of talking to him, and he doesn't understand." A man said: "These people can only talk, why don't we develop a vertical launcher similar to MK41? All kinds of our missiles are stuffed into it. How does he know the specific technical problems in it."

Qin Tao is not wearing a military uniform, but a denim work uniform, which is very reminiscent of a worker in a certain factory. He usually likes to read newspapers and magazines, and thinks that he is very knowledgeable, so he can give advice. , in fact, it is simply a layman pointing fingers at random.

"Pneumatic, you need to add an additional air source inside the missile, and hydraulic, you need to add a special hydraulic pump, which will increase the volume and weight of the missile, and electric, which needs to consume a lot of electricity inside the missile, so these are not suitable." Qin Tao didn't talk to the man, just talking to himself: "Obviously there is a simpler and more effective way to solve the problem, but I just don't think about it, and I always tie myself up with complicated problems and make myself a cocoon. It's a pity, a pity!"

   "Come, scrambled eggs with tomatoes." Pang Jianmin came over with the first fried dish: "Gong Qin, come and eat!"

   "Okay, thank you." Qin Tao picked up an 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 those big bright eyes, her lips twitched a few times, and then said, "Excuse me, is there any other simple method?"

   "Xiao Ling, don't ask him, this kind of person is just playing tricks."

  Qin Tao glanced at that guy, then shook his head: "Oh, some people, they have no skills, and they stop others from asking for advice humbly."

"you!"

   "Brother, stop talking." Xiaoling stood up, facing Qin Tao, and said solemnly: "This... teacher, I humbly ask you about folding the wings."

   "Don't make it so grand, as if I am very proud, I am actually easy to talk." Qin Tao said: "Move your stool, come and sit, eat with us, and I will introduce you."

   "Xiaoling, don't listen to him. It's not that we haven't considered it. Pneumatic, hydraulic, and electric are not suitable. The easiest way is to expand the volume of the launcher..."

  Xiaoling has already moved the stool over.

  Qin Tao took a glance. This technician was about the same age as her. She also called those men her seniors. He should have just graduated from university.

Short ear-length hair wraps a melon-seeded face, big eyes, long eyelashes, willow-leaf eyebrows, delicate and small nose and mouth, and looks like a kind of pure taste that has just stepped into the society, but there is a slight trace of something in those eyes. Bloodshot, it seems that I have been staying up late for scientific research projects recently.

   "Get to know each other. My name is Qin Tao. I graduated from the Shipbuilding Industry Institute. What about you?"

   "My name is Zhao Ling, you can also call me Xiao Ling, by the way, the problem of folding the wings you just mentioned..."

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

   "You can call me Taozi."

  Qin Baoshan was a little embarrassed there, little brat, what are you doing? If it was placed a few years ago, it would clearly be suspected of molesting lesbians.

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

   "Torsion bar?" Zhao Ling responded.

"That's right, it's the torsion bar." Qin Tao said: "Many problems have simple solutions. In addition to using those complicated external power methods for folding the wings, you can also add a simple The torsion bar is used as a torsion elastic part. 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 the launch frame, the elastic potential energy is released. , so that the missile wings are automatically expanded, especially for our surface-to-air missiles, the missile body exits the cylinder at a relatively low speed, and the aerodynamic resistance encountered by the folded missile wings during the deployment process after the missile flies out of the cylinder is relatively 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 launcher 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 kinds of methods are not easy to use, so they have to come up with this large cylinder.

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

   "So, how should the torsion bar be arranged?" Zhao Ling continued to ask.

   "This one is also very simple. I will draw a structure diagram for you. 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 that she carried with her, and opened a blank page in it.

  So, Qin Tao took a pencil and started to draw.

  A single-piece elastic wing with a torsion bar added to the root of the wing. Although Qin Tao didn't use a ruler, it was horizontal and vertical. Even the circles were drawn very standard, showing his excellent painting skills.

While drawing, Qin Tao continued to say: "Actually, even if the wings are not folded, there are ways to do it. For example, the cross section of the launching tube becomes square, the wings are distributed on the diagonal, and the wingtips are cut off. Partly, in this way, the six-pack launcher can also be turned into an eight-pack."
