The technology of rocket-propelled grenades is actually not complicated, and the Soviet Union at that time already had a relatively mature technology of solid rocket endurance engines, as long as the imagination is combined with a strong design team, the emergence of the РПГ rocket launcher is not very difficult. www.biquge.info It's just that what Lin Jun wanted was not the relatively conservative РПГ-2, but the РПГ-7 with a cruising engine (internationally known as RPG-7, which is the English named model, and all the following chapters are officially named in Russian. ）。

Although it is not as good as the Tokalov 33 on his waist, and he has never been an infantryman for a day in his previous life, he is very familiar with the **** bazooka: before entering the flight academy, he was systematically trained in **** bazooka shooting, and he also fired more than 30 rounds of live ammunition, and the structure of weapons and ammunition was also studied. Reverse design РПГ-7 with the memory of **** bazooka will avoid a lot of trouble, and the historical research basis of РПГ-7 РПГ-2 is a reference to the German "Iron Fist", which is a reverse design.

Drawing is a necessary skill for pilots, but I didn't expect Lin Jun to make a cameo appearance as an ordnance designer today: as soon as he arrived at the equipment department, Lin Jun asked people to get a full set of special tools and paper for drawing design drawings, and buried himself in drawing.

"The two ends are hollow to counteract the recoil generated by the instantaneous ******, and the launch canister is best to use light alloy, shoulder-mounted launch, and the shoulder part should be protected by a thermal insulation layer." Since it was only the initial sketch, Lin Jun completed the drawing of the launcher with a few brushstrokes, but the prototype of this launcher was the **** in his head, so there were more bipods than the РПГ-7 to increase the stability of shooting.

"The sight is optical, and it must have the dual ability of direct fire at close range and curved fire at long distance." Lin Jun was talking to himself there.

"Andrey, how much caliber is this?" Andlupuf asked, pointing to the launch canister on the drawing.

"Forty millimeters, at most not more than fifty millimeters, or the weight will be too large, and the specific will be determined by rocket experts according to the actual situation."

This is still clear to him: the design dimensions cannot be decided by himself, but also taking into account the current actual rocket technology.

"Wouldn't it be too small? It is possible that the warhead of this diameter will not be powerful enough. ”

"Haha, what are you anxious about, who said that the warhead is so little in diameter, I plan to use super-caliber ammunition."

Andlupuv was not an unheard of guy either, he knew several super-caliber explosive weapons, which were used by the Russian army in the Russo-Japanese War.

Lin Jun then drew the general shape of the ammunition, "The rocket is like a stick inserted close to the casing, and the last is the instantaneous booster launch cartridge that automatically disengages from the launch port, which must be burned out in the launch barrel, and the endurance engine must be ignited at a safe distance from the rocket to avoid endangering the shooter, and the stability of the rocket's flight depends on the folding stabilizing wing that automatically opens." ”

At this time, Lin Jun found a problem - there was no concept of concentrated armor-piercing bullets in this world, and it seemed that his knowledge beyond the times and the applicable rights could add a powerful ammunition to the Soviet cannon.

"That's it for today, it's late, and if they don't go back, they'll have an opinion."

"Then you want me to see your design when it comes out, and my appetite is hanging."

"No problem." Lin Jun said to his brother. "Fekochinov, there are a few things you can record. Call the Ammunition Research Institute in Tula and ask them to send two explosive bomb experts to me tomorrow morning at 9 a.m.; I want the Moscow Institute of Nonferrous Metals to send two experts, who understand the copper alloy process, to come to me at half past nine; Thirdly, at 10 o'clock in the morning I will meet with experts in the study of solid rockets near Moscow. ”

Fekochinov quickly made a note on his notepad: "I'll do it immediately." ”

"Shaped armor-piercing bullets, good thing!" Lin Jun thought to himself: If the Soviet tanks were equipped with armor-piercing shells with copper medicine covers, the tank members of those potential opponents on the battlefield would suffer.

On the 26th, Lin Jun spent the whole day in the office, from the 6 experts in the morning to the more than 20 experts who had dinner together, and experts from all aspects continued to rush to the equipment department throughout the day, and this situation lasted for a whole week.

On February 5, Lin Jun received an order to be summoned by Stalin.

"Andrey, I heard that you are making a big move in the armament department, and you have designed a variety of new weapons and ammunition by yourself."

"Yes, Comrade Stalin, today I was going to report to you that there are three types of equipment and one ammunition. All the designs have been preliminarily coordinated with experts in various fields, and they are feasible from the current technical point of view, and it is estimated that the combat capability of our army's aviation, artillery, tank units, and infantry will be improved to a certain extent. ”

Lin Jun placed a large stack of design drawings on Stalin's desk, where he could be said to be the most "casual" guy.

Stalin's love for new weapons is not inferior to that of the leaders of other countries, and he has been paying attention to Andrei's work in the armament department, and of course someone will report the special situation that arose this week, but he only speculates that it may be related to new weapons, and because of Lin Jun's meticulous secrecy work, even Stalin cannot get more information -- you must know that his current designs will have a great impact on the war, and how can he do it without doing a good job of secrecy, For this reason, Lin Jun also asked Alexander to directly send someone as a guarantee for the confidentiality work.

"This is a type of artillery shell that I designed and conceived, mainly to destroy local armored targets and strong fortifications." Lin Jun pointed to the first drawing and said.

"Andrey, this is supposed to be a blasting projectile, but why is there such a large space in the warhead?"

Stalin was not weapon-blind, he could see the way at a glance.

"Hehe, Comrade Stalin, this is not an ordinary explosive bomb, I call it a shaped armor-piercing projectile. You see, the solid part here is the explosive column, which is a specially made conical hollow recess, in which a copper conical cover is lined with a fuse at the bottom of the column. When a shell hits a tank, the bottom fuse detonates the explosive column, creating extremely high pressure on the outer surface of the dome. The dome is squeezed into a long, thin jet like a dough, hitting the tank's armor at a speed of several kilometers per second. I have already studied with a number of our experts who study alloys: in the face of metal jets, the steel plate of the tank cannot stop the penetrating force after compression and polymerization. ”

In front of the two of them was a fine design drawing of the shaped energy armor-piercing projectile, and after the efforts of the past few days, the drawings that Lin Jun brought to Stalin were no longer sketches with a few brushstrokes.

"This kind of shell can not only be used against tanks, used to destroy reinforced concrete point targets is estimated to have a very high damage effect, but also can be designed into various calibers to equip various types of anti-tank guns, conservatively estimated that the thickness of the steel armor will be three to five times the diameter of the ammunition, and has little to do with the speed of the shell and the hit distance. Judging by the reaction of the ammunition design department, the time and cost of the manufacture of such shells will not be much more troublesome than the current armor-piercing shells. ”

Stalin was completely attracted by this new type of shell: "When will there be a finished product?" ”

"We will be able to come up with a sample of a 76.2 mm tank gun in three months at the earliest."

"Well done Andrey!" Stalin patted Lin Jun on the shoulder, he already understood the potential value of this new type of shell: three to five times the armor-piercing ability, if it was a 76.2 mm shell, that is, it could penetrate the frontal armor of all heavy tanks with a large angle of inclination - Stalin did not think that in a few years there would be any tank with a thickness of 200 to 300 mm of inclined armor.

"Of course, we can't give up the research of new kinetic armor-piercing shells, because the estimated accuracy of armor-piercing shells at long distances cannot be compared with armor-piercing bullets."

"Andrey, it's already good. How did you come up with this design, and why do so many experts not have ideas for you? ”

It was not the first time that Lin Jun had surprised him, and sometimes Stalin also suspected that this beloved general was not a "person".

"You know I'm going to come up with something out of the ordinary when I'm fine, and that's it. Comrade Stalin, the second design I brought was an anti-tank weapon that could be equipped up to the infantry squad, and the effect should be much better than the existing anti-tank guns of various countries. ”

The second chapter of the drawings was a detailed drawing of the РПГ-7, and when Stalin had heard the design and function of this strange-looking weapon, he no longer knew what words to use to praise his beloved general.

"To use a special noun to explain that this should be a rocket-propelled grenade, but I estimate that after equipping the troops, comrades may like to call it an infantry squad cannon, because it has two ammunition and aimed firing modes: armor-piercing shells should be able to hit point-shaped hard targets at a distance of 150 meters, while blasting anti-personnel shells can destroy enemy forces within 400 meters, but the accuracy of hitting is estimated to be inferior to mortars. Therefore, from the comprehensive consideration of production technology and cost, this weapon should still be mainly used to deal with hard targets such as enemy armor. ”

After listening to Lin Jun's introduction, Stalin still said: "When will there be a sample?" ”

"Because this kind of weapon requires the joint design of multi-departmental forces, it is estimated that it will take half a year for the design of the shaped energy armor-piercing bullet to be basically mature."

The third design is the six-barrel rocket nest, and this design should be slowed down, because the 132-mm self-propelled rocket launcher with 24 I-shaped launch tracks marked in the fourth drawing will be the focus of the design of the rocket artillery department.

"Andrey, I officially appoint you as the first deputy political commissar of the General Armament Department of the Red Army, and the work is only responsible to the National Defense Committee, and if necessary, you can bypass the People's Commissar of National Defense."

patted Lin Jun on the shoulder again: "Andrei, I don't know how to commend you for your contribution to the Soviets again."
