    Chen Er hastily finished his meal and hurried back to the dormitory. Li Jun looked leisurely and contented and said, "Second brother, why are you so busy every day? You don't know that this is bad for your health.  As the saying goes, the body is the capital of revolution. If you ruin your body, then any ideas you have in the future will be in vain. I think you really need to get married quickly and find someone to take care of you. " Regarding Li Jun's words, Chen Erzhi said.  Neng sneered and said: "Don't talk about me, I am diligent after all. You kid lives a loose life every day. I think you really need to find a wife to take care of it. By the way, you know  Are our cafeterias busy making fried noodles? The Korean battlefield is very tight now, and I don¡¯t know what the situation is there. It¡¯s approaching winter, and this war will definitely be harder to fight. " Li Jun also agreed.  Said: "Yeah, I heard that it's hard for the soldiers on the front line to even have a hot meal. This damn Yankee, relying on his air supremacy, keeps bombing indiscriminately every day. This  In their eyes, artillery shells seem to be free of charge. When will we, China, have the absolute strength to compete with them in the air? This battle is also a bit fiery. " Although that is said, if we want to rely on it.  Now that China's air force is competing with the United States, it is undoubtedly a fantasy. Although it has the help of the Soviet Union, it still cannot gain much advantage in the air.  Compared with the United States, China's military strength is really too weak. In future wars, it is estimated that it will be difficult to achieve victory that costs lives.  The next day, Chen Eryi came to the special research team and started to get busy. He still remembered what his master said to him last time. There was an urgent need for weapons that could restrain tanks and chariots on the Korean battlefield.  The first thing Chen Er thought of was that big anti-tank mine. As soon as a tank rolled over it, it would definitely result in a vehicle crash and death. However, Chen Er soon gave up the idea of ??making anti-tank mines.  Firstly, the production process of anti-tank landmines is relatively complicated and not easy to produce in large quantities. Moreover, they are one-time equipment. Secondly, anti-tank landmines are more used in defensive warfare and are difficult to play a major role in mobile warfare.  effect.  You can't just run in front of the enemy and plant anti-tank mines when they are retreating. On the Korean battlefield, the probability of doing this is obviously very small. In addition, it is winter again, and the soil has already frozen.  Landmines were even more difficult to come by, so Chen Er decisively chose a 40-fire weapon that was more suitable for his current use.  The Type 56 40mm rocket launcher is a copy of the former Soviet PNT-2 rocket launcher.  This rocket launcher uses the reaction impulse of the jet gas after burning gunpowder to provide flight kinetic energy for the warhead. It does not have a rocket engine in the modern sense. The rocket engine is the launch tube itself. The gunpowder package is fixed at the tail of the projectile. The launch tube is inserted from the mouth of the tube. After firing, the gunpowder is fired.  After combustion, the gunpowder gas is ejected from the tail of the barrel at high speed, and its reaction impulse is used to obtain flight kinetic energy for the bullet; the warhead is an 80 mm hollow charge energy-gathering warhead; the tail boom is equipped with a stabilizer wing made of a spring leaf.  This rocket launcher is suitable for combat in mountainous jungles and can deal with enemy solid bunkers, tanks and other targets.  The Type 56 40mm rocket launcher adopts a balanced ejection principle similar to that of a recoilless rifle. The launch tube is open and can be divided into two parts: the barrel body and the launcher.  The barrel is made of high-strength seamless steel tubes, with a smooth interior and an anti-ablation chromium coating.  The inner diameter of the entire barrel is the same from front to back, and there is no expansion cavity at the tail of the barrel. The high-temperature and high-pressure gas generated by the combustion of the drug tube during launch is directly ejected from the tail of the barrel.  However, the outer diameter of the launch tube is not exactly the same. The mouth and tail are relatively thick to ensure strength. The diameter of the middle and rear part of the barrel is thinner, but there are several thicker protrusions used for welding the strap ring and installing heat insulation.  casing.  There is also a positioning gap above the barrel mouth, which is used to position the projectile when inserting the rocket to ensure that the primer part of the rocket is exactly aligned with the firing pin.  The upper part of the launch tube is welded with a steel plate stamped sight constellation and a rear sight base. The seat is equipped with a bow-shaped spring leaf to support the front sight and rear sight.  The square front sight is 3 mm wide. Like the rear sight, it is stamped and bent from a steel plate, and is then fixed to the front sight constellation and sight base with a pin.  There are three notches on the frame-shaped rear sight, and three sets of numbers 150, 100 and 50 are engraved from top to bottom below the notch, corresponding to the corresponding three shooting distances.  Although the range of the 40-fire is only about a hundred meters, its warhead is powerful enough to penetrate the armor of most current tanks, and the 40-fire does not have high requirements in terms of manufacturing technology and accuracy. General arsenals can do it.  Independently manufactured by himself, this is definitely the most suitable anti-tank weapon for the Korean front line. Chen Er looked at the drawings he drew and nodded with satisfaction.  The drawings have been completed, and Chen Er can¡¯t wait to get busy. Anyway, he only needs to design a rough model, and the accuracy requirements are not that high. Soon a transmitter will be onThe second hand slowly took shape.  Seeing Chen Er constantly working on a pipe, Murong Wan said to Wen Jing with some doubts: "Wen Jing, look, what is Chen Er doing? What's the point of tinkering with a pipe? Even if it's a gun,  You can't use such a thick steel pipe. Judging from his excited look, he must be making some tools for himself. This is an act of seeking public benefit for personal gain. Let's just ignore it." Wen Jing raised her head casually.  She glanced at Murong Wan and said: "My eldest lady, this is a special research team, okay? Don't make such a fuss about everything. Chen Er is the team leader here, and we are just his assistants. You are not the director of the factory. Don't worry.  Read your own book.¡± After hearing Wen Jing¡¯s words, Murong Wan curled her lips and said, ¡°I¡¯m just curious, why don¡¯t we two go over and take a look. Anyway, we¡¯ve been reading this for several hours. Let¡¯s take a rest.  It's okay for a while." Unable to resist Murong Wan's plea, Wen Jing could only accompany her towards Chen Er.  When she got closer, Murong Wan finally saw clearly what Chen Er was tinkering with. It was really a steel pipe, but it looked like there were some problems. As for the specific problems, she just couldn't tell.  Chen Er was concentrating on working on his launcher at this time, and did not notice that there were two more people around him. It was not until he completed the last process that he said with some surprise: "When did you two come here?" Murong  Wan Yi felt a little unhappy after hearing Chen Er's words. She and Wen Jing stood here for a long time and were mercilessly regarded as nothing. Without looking at Chen Er, she said: "You always have to rest when you are tired from reading.  I didn¡¯t know what you were doing, so I came over to take a look out of curiosity. I didn¡¯t expect you to be tinkering with such a broken steel pipe. If I had known about it, I wouldn¡¯t have come here.¡± He pulled Wen Jing and was about to leave.  Chen Er chuckled and said: "You are totally wrong about this. Don't underestimate this steel pipe. This is actually a launcher. When I find other masters to help me make the shells, this will be a launcher."  It's a complete weapon. Don't look at it, but its power is definitely not comparable to grenades." When Murong Wan and Wen Jing were in a daze, Chen Er quickly went to find someone to make the shell.  By the time Murong Wan came back to her senses, Chen Er's figure had already disappeared. Murong Wan murmured to himself: "Really or not, if weapons are so easy to invent, then I can be the one."  He is a weapons master." At this time, she suddenly saw a drawing on Chen Er's desk. She picked it up and looked at it carefully and exclaimed: "It's really a drawing of a weapon. What on earth did he think?  "It came out." Wen Jing also quickly took it and took a look. The paper was indeed a drawing of a launcher, and the various coefficients were clearly marked. There were also the production parameters of the cannon below. Wen Jing carefully  After putting the drawings on the table, he 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 like. It really makes me envious."  "Ah." "What's there to envy? Isn't it just that he has some weird ideas, that is, he came earlier than us, otherwise maybe the two of us can become the leaders of some special research group." Murong Wan said.  He said with an unconvinced look.  Chen Er ran to the production workshop in one breath. After working together with several masters for more than an hour, a cannonball was finally completed.  Of course, because this is the first time that the worker masters have made such a cannonball, the production time seems a bit long, but Chen Er believes that if he is familiar with this production process, one cannonball will only take half an hour at most.  After bidding farewell to the masters in the production workshop, Chen Er walked excitedly towards the factory director's office. Naturally, he wanted to be the first to show his research results to his master Wang Shengli.  When he came to the factory director's office and saw that Li Jun was there, Chen Er still couldn't hide his inner joy and said: "Master, look at this thing in my hand. I call it 40-fire. It is definitely the best weapon for tanks and other equipment on the battlefield."  The nemesis of all kinds of tanks." After listening to Chen Er's words, the three of them quickly came to the shooting range. Li Jun said excitedly: "Second brother, it's finally time for me to show off my skills. How do I use this 40 fire?  " He explained to Li Jun in detail the use of 40mm fire. Chen Er and Wang Shengli stood far away. After Li Jun loaded the shell into the launcher from the front, he carried it and aimed it at a distance of 70 or 80 meters.  pile of rubble.  As Li Jun moved his finger on the trigger, he heard a "swish" sound and a shell flew out. In less than a second, the pile of rubble was blown up in all directions, and the ground was still there.  A deep pit appeared.  Li Junli was in a daze on the spot. He didn't expect this thing to be so powerful, and he was really frightened.  When the smoke and dust dispersed, Wang Shengli hurried over to check.He walked down to the explosion site, and when he came back, he patted Chen Er on the shoulder and said, "Boy, you have made a great contribution this time. According to the power at the scene, these 40 fires can definitely penetrate the armor of the tank. This  The Yankee tanks can no longer be awesome. I have to report to my superiors quickly.  ¡ª¡ª"  , please recommend, thank you all for your support!  !  !  !  !  !  !  !  !  !  !  !  !  !  !  !  !  !  !  !  !  !  !  !
