Chapter 659 You are so good, does your teacher know?
After finally getting a group of unruly guys under control, Liu Lang had just driven them away and before he had a chance to smoke a cigarette and take a sip of water, Liu Lang heard the guards on duty outside the door arguing with someone.
What, the sound sounds a bit familiar.
Liu Lang stood up curiously, walked out of the door and took a look, and couldn't help but smile. Isn't that an acquaintance?
It was Su Xiaomei, the youngest among Comrade Lao Ye's students. Although he was young, his sharp thinking and to-the-point answers that day left a very deep impression on Liu Lang.
It was a sultry day, but "Su Xiaomei", who still covered herself tightly, stared at her round eyes, bulging her cheeks with baby fat, and was arguing with the guard ten meters away from the door.
But obviously, because of the regulations, the soldiers in the guard platoon had no intention of letting him in no matter what he said.
"Haha, Yan Qiguan, let Su Xiaomei come in! From now on, there is no need to stop Xiong Zhen and the others, let them come in directly." Liu Lang laughed and shouted from a distance.
"Captain Liu, what should I say? These guys under you are disciplined, but they are a bit stubborn." After entering the courtyard gate, Su Xiaomei, who was blocked at the door for a long time, was obviously still angry and depressed.
Complaining.
"Haha, they didn't receive my military order. They failed in their duty by letting you in. If you want to blame me, it's my fault for neglecting it." Liu Lang explained to this somewhat immature student with a smile.
"That's true, but I'm being petty." Su Xiaomei's face showed a hint of surprise, and then she seemed to have remembered something and peeked out the door.
Liu Lang brought a bench over and asked with a smile, "What's wrong? There are Bears, Big Bears and the others chasing you?"
"No, Captain Liu, do you know what projects Senior Xiong and Senior Qian have asked me to take charge of? If I'm not convinced, I'll come to you to file a complaint. Naturally, I have to be on guard against them." Su Xiaomei's northern words had a bit of a hint.
Wu Nong spoke softly, and his voice that had not changed was still a bit crisp, which was quite pleasant to the ear.
"Haha, don't worry, even if you complain, no one will dare to cause trouble for you." Liu Lang was amused by the children.
"I remember Professor Ye said that you only entered school last year. I'm afraid he brought you to Guangyuan because he wanted to show you the wonderful world outside! You should still learn more from your teachers and seniors." Liu smiled.
Lang took the tea brought by Sanchuan'er, put it in front of Su Xiaomei, and admonished.
"Huh, Commander Liu, how can you look down on people?" Su Xiaomei's eyes widened, and she angrily spread the drawing in her hand in front of Liu Lang, and an oval rocket cross-section was clearly displayed on it.
"This is..." Liu Lang was stunned for a moment.
"This is the rocket structure diagram that I spent a week designing." Su Xiaomei pointed to the graphic she drew and proudly introduced: "Look, here is the explosive. I call it the combat head. Here is the rocket launcher.
The fuel chamber is just like the flying monkey. Do you understand? I call it the propulsion part. It ignites the fuel, ejects it backwards, pushes the rocket out, ignites the explosive according to the time, and finally explodes.
.....”
Liu Lang looked horrified, looking at the handsome little boy with a babyish look on his face. Yes, when he explained the principles of rockets to Xiong Zhen and the others, he had basically understood the flight of rockets.
The principles were explained to them, but in just one week, this person actually drew drawings that were almost the same as those of later generations.
Liu Lang was sure that the drawings he had seen in the arsenal were almost the same as this hand-drawn one. Could this little boy have come from time travel? Otherwise, Liu Lang would never have imagined what would happen in the future.
You are of such an age and your surname is Su. Are you that ignorant? After all, he is a third-generation red man with good roots, okay?
However, Liu Lang's surprise continued.
"Captain Liu, I came to you today because I actually have two very important questions to ask you." Su Xiaomei looked back at Liu Lang with a serious face.
"you say."
"You are an ordnance expert, you are here to comment. Rifled guns are more accurate than smoothbore guns because there are riflings in the barrel, which allows the shells to rotate in the air to maintain ballistic stability. If the rocket launcher we want to develop does not want
After being shot out of the muzzle, it flies around like an ancient divine machine arrow, so shouldn’t the rockets also be allowed to keep rotating?”
"That's right." Liu Lang took a breath and nodded with his teeth bared.
·"Senior Xiong is more inclined to use the center of gravity rudder proposed by Senior Qian to maintain the rotation of the rocket in the air, but rejected my design. You are very angry." Su Xiaomei angrily complained to herself about the black status of the two seniors.
.
Liu Lang......
You haven't said what your design is yet! The two Xiong Qian used the most common method in this era, and it is normal.
"What's your design?" Liu Lang's voice became a little cautious since he saw the monster-like drawings.
He no longer dared to underestimate the kid in front of him, especially after he showed such an amazing talent.
"My design is much simpler than theirs. It uses a turbine rotation method, which is to use one nozzle at the tail of the rocket instead of several. Each nozzle is deflected at a small angle from the center line of the rocket. In this way, after the rocket is ignited,
, the propellant can push the rocket forward while pushing the rocket to rotate like an ordinary rifled gun shell." Su Xiaomei said with a bit of arrogance.
"Your design is very correct, and I fully support it." Liu Lang slapped the table and said with certainty.
In my memory, the 107 rocket seemed to use turbine rotation to keep the shell rotating in the air. Although Liu Lang didn't know how it was maintained, Liu Lang felt that Su Xiaomei's design was very advanced and awesome and could definitely be realized.
.
"Hehe, I know that Captain Liu, your vision is different from those stupid seniors." Su Xiaomei raised her head and smiled brightly, showing two beautiful little tiger teeth.
Liu Lang was sweating. Su Xiaomei could say this, but he didn't dare. Those people will be the top figures at the pinnacle of science in the Republic in the future. Even his high-ranking old man faced those people.
It’s also a great courtesy.
"There is another problem, which is the fuel for rocket propulsion. The seniors insist that gunpowder is used, and the propelling force generated by the high-pressure gas generated after the gunpowder is burned is sprayed backward to make the rocket move forward, but I think,
If you use gunpowder, the range is not enough. If you want to increase the range, you must increase the amount of gunpowder and increase the weight of the rocket. You have made specific requirements for the weight of the rocket, which cannot be higher than 18 kilograms. I know that
For the sake of transportation, a soldier can carry up to two rockets. If the weight is greater than this, he can only carry one rocket at most. However, if the rockets want to maintain sufficient power, the explosive part cannot be reduced, and it must be
In order to prevent the high temperature generated by the fuel from affecting the explosives in front of the rocket, the rocket has extremely high requirements for the steel of the combustion chamber, which also requires a huge amount of mass.
However, if you cannot maintain a longer range, you cannot suppress the Japanese invaders' artillery. You must know that the Japanese invaders' Type 41 mountain artillery has a range of 6,000 meters, but that is not their main artillery. Their main artillery is the 150-meter howitzer.
It can reach 12,000 meters. As the main artillery of the independent regiment, the Storm Rocket Launcher will only be useless in wartime if it cannot suppress the main artillery of the Japanese invaders. This does not meet the needs of the independent regiment. It also makes me Huaqing University School of Science
Shameful..." Su Xiaomei clenched her fists and talked passionately.
Liu Lang almost admires this kid. This girl wants to fly like an extended-range rocket! Do your teachers and seniors know that you are so cool?
