Chen Er hurriedly returned to the dormitory after eating, Li Jun looked leisurely and complacent, and said: "Second brother, why are you so hot every day, you don't know that this is not good for your health, as the saying goes, the body is the capital of the revolution, if you collapse your body, then it will be useless to have any ideas in the future, I think you really have to get married and find someone to take care of you." ”

Regarding Li Jun's words, Chen Er could only scoff and say: "Don't talk about me, I'm so diligent, you kid lives loosely every day, I think you really have to find a daughter-in-law to take care of it." By the way, do you know that our canteen is stepping up to make fried noodles? Now the Korean battlefield is quite tight, and I don't know what the situation is over there, and now that it is approaching winter, this battle will definitely be even more difficult to fight. ”

Li Jun also echoed: "Yes, I heard that the soldiers on the front line are very difficult to eat even a hot meal, this damn Yankee, relying on their own air supremacy, knows a vigorous bombardment every day, this shell seems to them as if they don't need money, when will we China have the absolute strength to compete with them in the air, this battle is also a bit of a nest." ”

That being said, it would undoubtedly be a fool's dream to rely on China's current air force to compete with the United States, and despite the help of the Soviet Union, it still can't take much advantage in the air. Compared with the United States, China's military strength is really too thin, and in a future war, it is estimated that it will be difficult to reappear such a victory that takes human lives.

The next day, Chen Eryi came to the special research team and began to get busy, and he still remembered what his master had said to him last time, that there was an urgent shortage of weapons that could limit tanks and combat vehicles on the Korean battlefield. The first thing that Chen Er thought of was that kind of big anti-tank mine, as long as the tank rolled up, it would definitely be the end of the car being destroyed and people killed, but soon Chen Er gave up the idea of making anti-tank mines.

First, the process of making anti-tank mines is relatively complicated, and it is not easy to produce them in large quantities, and they are one-time equipment, and second, anti-tank mines are more used in defensive warfare, and it is difficult to play a great role in sports warfare. You can't run in front of the enemy when they retreat to bury anti-tank mines, in the Korean battlefield, obviously the probability of doing this is extremely small, and it is now winter, the soil has already frozen, and it is even more difficult to bury mines, Chen Er decisively chose a weapon that is more suitable for use now.

The Type 56 4o mm rocket launcher is an imitation of the former Soviet pnT-2 type bazooka. The rocket launcher adopts the reaction impulse of the jet gas after the gunpowder combustion to provide flight energy for the warhead, it does not have a rocket motive in the modern sense, the rocket motive is the rocket itself, the gunpowder bag is fixed at the tail of the bullet, the projectile is inserted from the barrel mouth, the gunpowder burns after the shot, the gunpowder gas is sprayed from the tail of the barrel, and the reaction impulse is the projectile to obtain the flight energy; The warhead is an 8o mm hollow charge shaped warhead; The tail boom is equipped with a stable wing made of spring plates. This rocket launcher is suitable for mountain and jungle combat, and can deal with enemy solid bunkers, combat vehicles and other targets.

The Type 56 4O mm rocket launcher adopts a balanced projectile principle similar to that of a recoilless gun, and the projectile is open, which itself can be divided into two parts: the barrel and the projector. The barrel is made of high-strength seamless steel tubes, with a smooth interior and coated with an ablation-resistant chrome layer. The inner diameter of the whole cylinder body is the same before and after, and there is no expansion chamber at the end of the cylinder, and the high-temperature and high-pressure gas generated by the combustion of the medicine tube is directly sprayed from the tail of the barrel.

However, the outer diameter of the barrel is not exactly the same, the mouth and tail are relatively thick in order to ensure strength, and the diameter of the middle and rear parts of the barrel is thinner, but there are several thicker protrusions, which are used for welding the strap ring and installing the heat insulation cylinder. There is also a positioning gap above the barrel mouth, which is used to locate the projectile body when inserting the rocket, and ensure that the primer part of the rocket is just aligned with the firing pin.

The upper part of the barrel is welded with a steel plate stamped and formed front sight and a gauge base, and a bow spring plate is provided in the base to support the front sight and gauge holder. The square crosshair is 3 mm wide and, like the ruler, is stamped and bent from sheet steel, and then fastened to the crosshair and ruler base with a pivot pin. There are 3 notches on the frame-shaped ruler, and three sets of numbers 15O, 1oo and 5O are engraved below the notches from top to bottom, corresponding to the corresponding three shooting distances.

Although the 4O fire is only about 100 meters in range, the power of its warhead is enough to penetrate the armor of most tanks now, and the 4O fire does not have too many requirements in terms of manufacturing process and accuracy, and the general arsenal can be independently manufactured, which is definitely the most suitable anti-tank weapon for the Korean front, Chen Er looked at the drawings he drew and nodded with satisfaction.

The drawings have been completed, Chen Er can't wait to get busy, anyway, he only needs to design a rough model, and the requirements for accuracy are not so high, and soon a shooter will slowly take shape in Chen Er's hands.

Seeing Chen Er constantly processing a pipe back and forth there, Murong Wan said to Wen Jing with some confusion: "Wen Jing, look, what is Chen Er doing, what is he doing with a pipe, even if he makes a gun, he can't use such a thick steel pipe." Looking at his excited face, could it be that he is doing some tool for himself, this is an act of public and private gain, let's take care of it. ”

Wen Jing raised her head and glanced at Murong Wan casually and said, "My eldest lady, is this a special research team, don't make such a fuss about everything, Chen Er is the leader here, we are just his assistants, and you are not the factory director, so read your own books with peace of mind." ”

After listening to Wen Jing's words, Murong Wan pursed her lips and said, "I'm just curious, why don't the two of us go over and take a look, anyway, it's been a book I've been reading for hours, so it's okay to take a break." Unable to withstand Murong Wan's begging, Wen Jing could only accompany her towards Chen Er.

When it got closer, Murong Wan finally saw clearly what Chen Er was messing with, it was really a steel pipe, but it seemed that there were some problems, as for what was the problem, she just couldn't say. Chen Er was concentrating on his shooter at this time, and he didn't notice that there were two more people around him, and he didn't say with some surprise until he completed the last process: "When did you two come over?" ”

Murong Wan was a little unhappy when she heard Chen Er's words, feeling that she and Wen Jing had been ruthlessly treated as air by standing here for a long time, and she said without looking at Chen Er: "I always have to take a break when I'm tired of reading, I don't know what you're doing, so I'm curious, so I'm curious, I came to take a look, I didn't expect you to be tinkering with such a broken steel pipe, I didn't know it would have come." Saying that, he pulled Wen Jing to leave.

Chen Er smiled and said: "You are very wrong, don't underestimate this steel pipe, this is actually a shooter, wait for me to find other masters to help me make the cannonball, this is a complete weapon." Don't look at its appearance, it's definitely not a grenade or anything like that in terms of power. When Murong Wan and Wen Jing were a little stunned, Chen Er quickly went to find someone to make a cannonball.

By the time Murong Wan came back to his senses, Chen Er's figure had already disappeared, and Murong Wan muttered to herself: "It's really fake, if the weapons are so good, then I can also be a weapon master." At this time, she suddenly saw a drawing on Chen Er's table, picked it up and looked at it carefully, and couldn't help but exclaim: "It's really a blueprint of a weapon, how did he come up with it." ”

Wen Jing also hurriedly took it and looked at it, the paper was indeed drawn with a drawing of a shooter, and all kinds of coefficients were clearly marked, and there were also the parameters of the cannonball below, Wen Jing carefully put the drawings on the table and said: "Wan'er, you should believe it now, our team leader Chen is not comparable to ordinary people, I really don't know how his head looks, it really makes me envious." ”

"What's there to envy, isn't it just some strange idea, that is, he came earlier than us, otherwise maybe the two of us can become the leaders of some special research team." Murong Wan said with a look of disberence.

Chen Erqi ran to the production workshop in one breath, and with the full cooperation of several masters for more than an hour, a cannonball was finally completed. Of course, because this is the first time that the workers and masters have made such shells, the time to make zuò seems to be a bit long, but Chen Er believes that if he is familiar with this process of making zuò, a cannonball will be half an hour at most. Bidding farewell to the masters in the production workshop, Chen Er was excited to walk towards the factory director's office, and his research results were naturally the first to be shown to his master Wang Shengli.

When he came to the factory director's office and saw that Li Jun was also there, Chen Er still couldn't hide the joy in his heart and said: "Master, look at this thing in my hand, I call it 4O fire, it is definitely the nemesis of tanks and various combat vehicles on the battlefield." After listening to Chen Er's words, the three of them came to the shooting range quickly, and Li Jun said excitedly: "Second brother, it's finally time for me to show my skills again, how to use this 4O fire?" ”

After explaining the use of 4o fire to Li Jun in detail, Chen Er and Wang Shengli stood far away, and Li Jun loaded the shell from the front into the injector, and then carried it and aimed it at a pile of gravel seventy or eighty meters away. As Li Jun's finger moved on the trigger, he only heard a "whoosh" and a shell flew out, and in less than a second, the pile of rubble was blown everywhere, and a deep pit still appeared on the ground. Li Junli was a little stunned on the spot, he didn't expect this thing to be so powerful, and he was really a little frightened.

When the smoke and dust cleared, Wang Shengli hurriedly went over to check the scene of the explosion, and when he came back, he patted Chen Er's shoulder and said: "Boy, you have made another contribution this time, according to the power of the scene, this 4o fire can definitely penetrate the armor of the tank, and now the Yankee's tank can no longer be angry, I want to hurry up and report to my superiors." ”
