Only then, a cheerful female voice came from behind Xie Yu, "Report, Director Meng, can I come in?"
Director Meng was stunned and said, "Oh, it's Teacher Bai Ge, please come in."
Soon a young and beautiful woman walked over from the door.
The woman glanced at Xie Yu and said, "Director Meng, this won't affect you!"
Director Meng said: "No matter what the influence is, come Comrade Bai Ge, I will introduce you to you. This person is Comrade Xie Yu."
"Xie Yu, this is Comrade Bai Ge. He is a top student at Peking University. He studied radio technology. This radio training organized by the special committee was organized under Bai Ge's suggestion."
Bai Ge glanced at Xie Yu and said excitedly: "You, you are Comrade Xie Yu, thank you so much. If it hadn't been for the more than ten Japanese radio stations you captured this time, the Special Committee would not have let me organize a radio station." Training classes.”
Xie Yu: "Comrade Bai Ge, your suggestion is very good. You see, our army will expand sooner or later. As long as it expands, communication will definitely be a big problem."
"This radio is a person with clairvoyance and ears. If it weren't for my poor cultural background, I would also want to learn it."
Comrade Bai Ge smiled and said: "Comrade Xie Yu, you are a great hero. If you want to learn wireless technology, you can just come to my class."
Xie Yu also had an idea and said: "Okay, I'll bother you when I have time, but I still have something to do, Teacher Bai Ge, you go ahead and do it!"
After Bai Ge exchanged a few words with Xie Yu, he watched Xie Yu leave.
Although Comrade Baige is very beautiful, it is impossible to say that Xie Yu has no ideas, but Xie Yu knows that it is a war era, and although he has a gourd mark, this gourd mark can only be used as a precaution.
The battle is dangerous. If Xie Yu is not careful and is covered by a wave of Japanese artillery fire, he will probably die no matter how well-prepared he is.
Xie Yu only hopes to defeat these hateful and cruel Japs as soon as possible, not only to avenge himself, but also to avenge the villagers who were killed by the Japs.
Thinking of this, Xie Yu put aside the personal relationship between his children and continued to study the Japanese grenade manual and notes, hoping to compile a suitable teaching material.
After Xie Yu's repeated use and research, he discovered that the grenade was, in principle, an ultra-light mortar.
The principle of this Japanese grenade is not very complicated. It also uses the parabolic principle to produce a mine thrower that relies on the principle of high and low voltage to launch.
The grenade used in the grenade has a propellant chamber at the bottom, which contains propellant.
The hole in the middle of the bottom of the grenade is equipped with a percussion cap.
After pulling the tape under the grenade barrel, the firing pin in the middle of the screw fires the flash cap at the bottom of the grenade to ignite the propellant.
The shooter adjusts the length of the screw in the launch tube by adjusting the range nut on the right side.
The length of the screw in the launch tube determines the spatial distance between the grenade and the bottom of the launch tube.
The grenade can adjust the chamber pressure during launch by adjusting this spatial distance. The size of the bore pressure determines the range of the grenade canister.
As for the grenade in Xie Yu's hands now, according to Japanese records, the name is the Eighty-Nine Type grenade, which was an improved version of the previous Taisho decade.
The caliber is also 50 mm, the total gun length is 413 mm, the barrel length is 260 mm, and the total gun weight is 2.7 kg.
The barrel weighs 1.6 kg, the barrel foot length is 170 mm, the barrel plate weighs 1.1 kg, the foot plate height is 60 mm, and the foot plate width is 67 mm.
The Type 89 grenade launches special grenades or Type 91 grenades. The special grenades have a maximum range of 700 meters, an effective range of 500 meters, and a grenade killing range of 10 meters.
The range of launching Type 91 grenade is about 200 meters, and the killing radius of the grenade is also eight meters.
The special grenade for the grenade can weigh 800 grams, and a bomb bag can hold four.
The Type 91 grenade is standard equipment for infantry. It weighs 0.45 kilograms. One ammunition bag can hold eight Type 91 grenades.
As a de facto simple mortar, the grenade is light in weight, has a moderate range, a large firing angle, and a curved trajectory.
It is mainly used to kill opponents hidden behind fortifications and concealments, or to kill enemy effective forces from a long distance.
It has good killing effect and is easy to operate. It can be carried by an individual soldier and move with the front-line infantry to support the front-line infantry.
And because of its small size, it can be carried by a single soldier and can be fired from behind obstacles. Its concealment is also very strong.
Xie Yu combined some factory learning and training experiences before time travel and made a rough 89-type grenade teaching material, and then officially entered his teaching career!
In fact, the principle of this grenade is really complicated. After about a week, thirty students have become familiar with the grenade in their hands.
After Xie Yu felt that he could do it, he began to apply to Director Meng for live-fire training for the students.
Because there were too few special grenades, less than a hundred, Director Meng did not approve them. However, this time tens of thousands of Japanese Type 89 grenades were seized in Wanjia Town.
Although Director Meng felt distressed, each student was awarded three coins for training.
Although it was still too few, Xie Yu had nothing to say and personally trained each student. Unfortunately, there was still a big gap between theoretical study and practice. Each student fired three Type 91 grenades.
It looked like it was normal, but the deviation was still twenty or thirty meters, which made Xie Yu very depressed.
After all, this grenade is not a real mortar. Coupled with the students' cultural level and psychological quality, if the hand shakes and the wind deflects, the launched grenade will be different.
Another week passed, and although the students still worked hard, they wanted Xie Yu to apply for live-fire training.
But Xie Yu knew that the students' skill in using grenades had reached a bottleneck, and a small amount of live ammunition training would not be of much use.
A large amount of live-fire shooting training can indeed improve the students' level. Unfortunately, this is unrealistic for the Eighth Route Army, which relies on capture for war.
However, Xie Yu, who had been taking classes with Teacher Bai Ge for two days, suddenly had an idea when he heard Teacher Bai Ge say a few words in foreign languages for training students.
This is how Xie Yu first started learning foreign languages when he was in junior high school. At that time, Xie Yu couldn't remember the pronunciation, so he marked it with words he knew.
In this way, although the teacher later criticized Xie Yu for his crooked ways, which would affect Xie Yu's oral expression ability, it did help Xie Yu to read out the foreign letters and remember them at first.
Later, because there was no listening test or anything, Xie Yu took several exams and got good results.
In this case, Xie Yu quickly found a few students who knew carpentry work, plus his own experience as a stonemason.
Make several wooden external hangers for this grenade, so that although the load of the grenade is increased, it is still useful for students who are new to learning grenade.
It can simply be constructed by adding a few new small wooden structures, allowing students to control the accuracy of the first shot within fifteen meters, and then adjust the second shot to hit.
After that, maybe you need more experience to be able to hit in the starting lineup.
Under the current realistic conditions, Xie Yu can only do this.
Later, after Xie Yu reported to Director Meng, Director Meng agreed with Xie Yu's opinion after careful consideration, coupled with constant urging from the local army.
Xie Yu's first grenade training class graduated in a hurry after training students for twenty years.
Although the thirty students of this class graduated in a hurry, they did play a great role in the subsequent battles and reduced a lot of casualties to the local troops.
