The reason why Wang Zhen is eyeing this Huawei brother is because this kid is the youngest in Che Yaxian's team, has good English, knows programming, has just graduated for a short time, is lively and active, and has a strong curiosity about military things.

During this time in Najishot, the others went to the vicinity of the barracks at first, but after two or three days they got tired of it, and this kid wanted to grow up in the barracks, relying on his good English, and he was familiar with many people, all kinds of firearms, and played all over again.

Usually, they don't go back to the accommodation arranged by Guo Jingyun for them, and they live directly in the barracks.

"We need talents like you for Glorious Defense!" As soon as he went back, Wang Zhen pulled up the Huawei brother named Dang Haobing to chat, "Can you design such a thing, through two devices suspended at an altitude of thousands of meters, to quickly complete the calculation of the straight-line distance between two specific targets and the calculation of the altitude difference." ”

"It depends on the accuracy you're looking for, if it's just accurate to the meter, it's super easy." Dang Haobing said with a smile: "Actually, there is no need to use two, one is fine, and the accuracy of one more will not improve much." ”

"What if you put this data directly into a ballistic formula?" Wang Zhen continued to ask.

"Huh? How do you sound like a fire control system? Dang Haobing's eyes lit up.

"Yes, I wanted to make a simple fire control system." Wang Zhen said with a smile.

"Isn't it good to buy? It's not expensive for you. ”

"Is the fire control system universal?"

"Of course not."

"So, we want to equip a weapon of our design with a fire control system, as long as it has a very simple function." Wang Zhen blinked.

"That's right." Dang Haobing thought for a while and said: "Different weapons, the ballistic trajectory is different, such as bullets, its ballistic trajectory is very easy to calculate, but replacing it with artillery is another concept, different sizes, different shapes, all different, what do you want to design a fire control system." ”

"In addition, everything else is easy to say, the key is how you are prepared to solve the anti-jamming ability of the military fire control system."

"If it is not solved, none of the current hypothetical adversaries will have electronic jamming capabilities." Wang Zhen said with some embarrassment.

Dang Haobing pouted slightly, what kind of fire control system is this, child's play!

"You need to look at things, get specific parameters, calculate ballistic formulas, and then make an app and install it in your phone." Dang Haobing said with a relaxed face.

Wang Zhen: "......"

God special APP!

Is it child's play?

"Really." Dang Haobing saw Wang Zhen in a daze and said with a smile: "Really, the only difficulty is to calculate the ballistic formula, you understand." ”

Wang Zhen: I don't understand.

"In this case, you come with me to have a look, and I'll tell you more about it when the time comes."

Now Dang Haobing is interested......

……

"It's rough, it's a rocket!" Dang Haobing's eyes lit up and he walked towards the rockets erected on the ground.

Lao Liu looked at Wang Zhen with a black face: Where did you find it, your mouth is so broken!

It's good to be rough, rough you make a look!

Damn, I have a manual machine tool and milling machine in my hand, it's good to be able to make it like this, and I'm not a high-end fitter!

Dang Haobing squatted there, touched the solder joint, and shook his head again and again, "This welding is not good, but there is no weld, how to test the strength, but there is no post-welding treatment!" ”

"Young man, okay, expert, I just can't find anyone to help me weld, come on, help." Lao Liu asked with a smile.

Wang Zhen smiled and didn't squeak.

"Ah, I won't." Dang Haobing turned his head to look at Lao Liu and replied directly, his eyes were clear and stupid.

As soon as he heard this, Lao Liu let out a 'ha' sound from his mouth.

The voice is not loud and extremely insulting.

"I'm a user, do I still need to know how the refrigerator is made!" Dang Haobing said disapprerovingly: "Do you understand the division of labor and cooperation?" ”

Lao Liu: I don't know the division of labor and cooperation!

The support team has a good welder and a CNC machine, so he can't carry this thing to someone to help!

"It's still far from the design stage, you're young, your brain is active, and you have some ideas to talk about." Wang Zhen smiled and made a round, "Our purpose is to design a rocket with a low price and a range of 20-50 kilometers, and we must try to pursue accuracy." ”

"Is there a propellant?" Dang Haobing's eyes lit up, he stood up and asked quickly: "Everything else is easy to say, there is no technical content, the main thing is propellant!" ”

Lao Liu stood straight with his waist straight, his head held high, and he had to fight for this breath back.

Wang Zhen pointed at Lao Liu, "Designers and chemists are here, and they have many years of experience in weapon design......

As he spoke, Wang Zhen suddenly paused, "Lao Liu, what's your name?" ”

"I'll fuck you uncle!" Lao Liu couldn't maintain his superior demeanor anymore, and he was angry on the spot, "After so many years, you don't know what my name is!" ”

"No, when Lao Hou introduced you, he was talking about Lao Liu, and everyone called it that after that!" Wang Zhen stalled his hands.

"I'm Nima!" Lao Liu said hatefully: "Liu Cunhua, you remember it for Lao Tzu!" ”

"Oh, what do you have to do with Andy Lau? Your brother? ”

"Get out!"

"You just call him Uncle Liu." Wang Zhen introduced with a smile.

"Don't listen to Xiao Wang's nonsense, what chemist, just to study chemistry in college, and have no experience in weapon shooting, when I worked, just in time for the third-line factory to turn into civilian, the transformation of the third-line factory basically failed, I was laid off early, these two years with Xiao Wang, only began to pick up these things, make some copycat armored vehicles, 107 rocket artillery, ultra-small aerial bombs, air bombs, howitzers or something......"

"Cool, I also want to learn weapon shooting, but if I don't pass the exam, I can only be reduced to being a code farmer!" Dang Haobing gave a thumbs up, his eyes were full of longing and admiration, he likes firearms and weapons, he is a fan of Yunjun, and even the real guy has only touched it in the past few days, let alone designed and manufactured.

Even theoretical knowledge is only superficial.

"No, aren't you a mechanic?" Wang Zhen wondered.

"You asked me to build an armed pickup truck at the time, of course I want to say that I learned mechanics, and you believe it when it comes to sales, idiot!" Lao Liu scolded.

"If I ask you to buy an airplane, you still tell me to learn astronautics!" Wang Zhen said angrily.

"That's called aviation, no culture, aerospace is space!" Lao Liu's eyes were full of disdain.

"Alright, let's get down to business." A college student in the early 80s, a post-90s college student, watching them brag about college, Wang Zhen graduated from junior high school with a pain.

"Uncle Liu, do you have any design drawings?" Dang Haobing asked.

"No words, I made the seamless steel pipe that was cut back directly from the cement factory site, mainly to test the propellant." Lao Liu said a little shyly.

"Uh......" Dang Haobing scratched his head, not knowing what to say for a while.

"What, there's nothing to say, according to your ideas, how should it be done?" Wang Zhen asked with a smile.

He saw that the set that Lao Liu learned back then was still something from the era of the third-line factory, although it was a serious military industry, but Lao Liu was only one of the countless links, although he learned a lot of things with the talent of college students, but he did not contact this in the following years, and he was completely outdated.

It belongs to the hands-on ability A level, the basic knowledge B level, and the thinking D level.

Hearing Wang Zhen ask, Dang Haobing pursed his lips and smiled, but his heart had already begun to surge, Yun Jun had been fascinated for so many years, and now he finally had a chance to play!

O heaven, O earth!

I'm coming!

"Normally, there should be a design goal first, first of all, range."

"30-50 km." Wang Zhen said.

"Why so far?" Dang Haobing frowned.

"Far away? What's the problem? ”

"Yes, the range of the Seahorse is 30-45, of course, if it is replaced by a tactical missile, the range is 300 kilometers." Dang Haobing is worthy of being a cloud player, and all kinds of data are recorded very clearly, "while Russia's Hail 122mm rocket artillery has a range of only 20 kilometers, and the TOS-1A 220mm rocket artillery has a range of only 6 kilometers." ”

"In actual combat, the two sides of the exchange of fire are more within a range of 20 kilometers, 30-50 kilometers, which is of little significance, and basically cannot be used."

"Deterrent weapons, you know, the kind that is basically impossible to use." Wang Zhen said with a smile: "I have you or not, I can defeat you and show our technical strength." ”

"Understood." Dang Haobing suddenly, "Imitation, traditional arts, direct imitation of the Seahorse, 227 mm caliber, 3.93 meters long, weighing 307 kilograms, warhead 154 kilograms." ”

"What is the warhead charge?" Wang Zhen thought about it, why can't Kasan 4 be displayed, the charge is only 25 kilograms.

"About 150 kg warhead, without navigation equipment, only if you blow up the fuse, 110 kg of charge." Lao Liu said uncertainly.

"The caliber of 227 mm, the length is 3.9-4.1 to give a fuzzy data, how to do the most reasonable air layout, whether to add a tail or put it in the middle of the bomb body, and the shape design has a 10,000 yuan to find two college students to design it for you."

"The most suitable shape is available, the rest is the ratio of the warhead charge to the propellant, so as to meet the design requirements of 50 kilometers, after all the conclusions come out, continue to go to the country to find college students, spend 10,000 yuan, there is the specific impulse and weight of the propellant, the shape plus the friction coefficient, you can calculate the speed of the rocket, and then you can calculate the flight trajectory according to the resistance, and finally calculate a formula."

"The rest only needs to substitute the data to calculate the landing point."

"Based on these paper data, we will soon be able to get a real ballistics table by conducting a live ammunition test of assembly and firing."

"With the ballistic table, I can write out the APP, get a wireless network card, motor generator, high and low machine, direction machine, and complete the adjustment and launch on my mobile phone." Dang Haobing smiled and gestured, "It's no different from playing a game." ”

At this moment, Lao Liu: Damn, I'm old!

Wang Zhen: Damn, there's no culture!

Also, is it so cheap and easy to use for college students now?

Don't you say that it costs 2 million to draw a Spring Festival Gala dragon?

10,000 yuan for college students?

It's cheap! (End of chapter)
