Jiang Tao, who retrieved the machine tool, was finally idle, and according to Murphy's Law, the more things he didn't want to happen, the more often they would happen

Just when he thought he could rest for two days, things came to his door. Pen ~ fun ~ pavilion www.biquge.info and this matter is also very in line with the saying of the ancestors, "Blessing is incomparable, and disaster is not a single line." "No, Chen Haisheng and Nie Hengyu came to Jiang Tao's door.

"Jiang Tao, Jiang Tao, come out for me." This loud voice and tone are so arrogant, I think there is no semicolon except for Chen Haisheng's family.

"Hey, here, here. My factory director, what's the matter? It's not a good habit to disturb dreams early in the morning. Jiang Tao, who was going to sleep well, was woken up in the morning, and his tone couldn't help but bring a little wake-up gas.

"You kid still has the face to say, look at when it's over, it's all three poles in the morning, you're still sleeping, look at anyone who is as lazy as you." Chen Haisheng can't see a lazy man like Jiang Tao the most.

"I think back then, when I built a factory, I didn't get up the earliest, I slept the latest, where was I like you......"

"Old man, if you have something to say, I will definitely change this lazy problem." Seeing that Chen Haisheng was about to start preaching Dafa, Jiang Tao hurriedly interrupted him, and he didn't know if this old man was the factory director who trained people too much, anyway, every time Chen Haisheng trained Jiang Tao, he could say that he didn't have to repeat it for a long time.

"You kid can't respect me, okay, I asked people to process the drawings of the anti-aircraft machine gun you got last time, but there are some problems with the processing, and it can't meet your design parameters at all."

"What, it shouldn't be." Listening to Chen Haisheng talk about the anti-aircraft machine gun he designed, Jiang Tao's sleepiness was gone, but there was something wrong with not meeting the parameters of the design.

"So, you shouldn't throw things at us, you also have to think about it together on the side, no matter who designs the weapon, it may not meet the parameters, don't worry too much." Afraid that Jiang Tao would be discouraged, Chen Haisheng still comforted Jiang Tao, don't look at the two of them who despise each other all day long, but in fact, they both regard each other as friends, Jiang Tao's patriotic feelings can be said to be very right Chen Haisheng's appetite.

"Okay, let's go check it out."

"Don't worry, there's someone looking for you outside the door."

Hearing what seemed to be a mention of himself inside, the man outside the door walked in. "Captain Nie, it's you." Seeing this person, Jiang Tao felt a little guilty when he arrived. To be honest, Jiang Tao really felt a little sorry for Nie Hengyu. Just now in the 918 time, the meeting "abducted" him, and then he has been ignored all the time.

"Jiang Tao, I said that Ha helped me and those students build airplanes, but recently the arsenal has just been rebuilt, and I can understand it, but now it's been more than a month, shouldn't you think about the plane you promised us before?"

"Okay, give me a month to make sure I can help you out." Jiang Tao gritted his teeth, the structure of the aircraft in this era is still relatively simple, otherwise he would not dare to agree to make an airplane in a month with a few guts, which sounds very unreliable.

It seems that he is going to be busy in the arsenal again, and it seems that even if he is born busy, Jiang Tao sighed, and went to the arsenal with Chen Haisheng, and then solved the machine gun matter first, as for the plane, it is not something that can be done by one person, and it has to be discussed with everyone.

"Director Chen, let's talk about what is wrong with the anti-aircraft machine gun, let's study and study it together." When he arrived at the arsenal, Jiang Tao asked about the machine gun without saying a word.

"It's not a big problem, you said that the effective range of this anti-aircraft machine gun should reach 1000m, and the maximum range should reach 1400 meters, but after we produced it, we estimated it according to the range of flat fire, and the anti-aircraft fire could only reach 1000 meters at most.

"Hey, it seems to be a matter of kinetic energy, can the charge of the bullet be solved?"

"It's okay to increase the charge of the bullet, but in this case, the chamber may not be able to bear it, and in this case, the recoil will also increase, and the accuracy is not very good, so that the muzzle of the gun will start to float without a few bullets."

"That's it......" Jiang Tao rubbed his chin and began to think, and when the people on the side saw it, they also began to try not to make a sound, for fear of disturbing Jiang Tao.

"In this way, factory director, let's add a brake to the muzzle to offset part of the recoil, and then we add a periscope on the side of the gun scope, so that the soldiers can hide in the trench for aimed shooting, so that even if the brake increases the noise and smoke, it is easy to be detected, but the soldiers can hide in the trench and ensure safety. Please get a batch of bullets to increase the propellant, so let's give it a try. ”

The bullets soon came, and the brakes and periscopes that Jiang Tao was also directing were also processed. Mounted on a sample gun. "Director, let's find a place to try."

Jiang Tao personally went into battle for the experiment this time, and a series of non-stop gunshots rang out in the experimental field, and the range of the guns was significantly improved, and suddenly there was a "bang" explosion. "It's broken, something happened" This reaction appeared in the minds of the surrounding onlookers, and Chen Haisheng immediately rushed into the test site.

"Ahem, it's fine." I saw that Jiang Tao himself walked out, and when he saw that no one was killed, the people around him breathed a sigh of relief.

"Something's going on, you're okay."

"It's nothing, it's just that the barrel of the gun is blown up." The people around him gasped when they heard this. No one can say that such a thing as a borehole is not good, if it is not serious, it is a gun damage, and if it is serious, it may be a life.

"It's nothing, your kid's heart is really big." Chen Haisheng was also taken aback by the explosion.

"It's really fine, don't worry." Saying this verbally, in fact, Jiang Tao himself was also frightened, and his legs were a little weak until now.

"Now that the firing range is solved, we are going to solve the problem of exploding the chamber, I guess it may be due to the inertial firing and the quality of the barrel that caused the exploding bore, and the inertial firing is easy to solve, we just use the mass of the hammer to reduce the mass a little. As for the barrel problem, I can't solve it, but I know someone has a solution. ”

"Who, you kid say it quickly."

"You also know this person as the factory director, it's Wenda."

"He, no, I thought it was gilded from above, but for the sake of Lord Sun Liechen's face, I didn't drive him away. It seems that I am old, and I don't know Taishan with eyes. Then call him over. ”

Jiang Tao shouted that a person on the side called Wenda.

"Wenda, do you see if there is a way to improve the quality of our barrel, so that it can withstand higher chamber pressure."

"Well, I don't know what's wrong with this barrel, you let me see it first." When it comes to professional issues, Wenda's usual shy appearance is gone. Jiang Tao handed the barrel of the gun to Wenda, and Wenda's words after careful inspection startled everyone.

"You're using this barrel to shoot a bullet with a larger volume, but luckily you're lucky, this barrel has cracked, but the bore isn't that bad."

"Is that because we have too many bullets?" Jiang Tao asked on the side.

"Partly because of that, but it just brought him to the chamber earlier. If you don't change the barrel and continue to shoot, the barrel will continue to expand under the action of alternating stress, and communicate with the microcracks around the inclusions, expanding, and eventually causing the barrel to crack. So it's only a matter of time before the bore is blown up. Venda lifted the tail of the barrel to look around.

"So can you fix this?" Chen Haisheng on the side asked Wenda anxiously.

"Yes is yes, as long as you use better steel."

"Hey," the people around him sighed in unison. "Wenda, if you use better steel, the cost is too high, and you know that the output of our smelter is not large, even this kind of steel is considered good. No matter how good the steel is, it is used to make cannons. ”

"Well, then give me some time, and I'll figure it out."
