"Talent!" Peng Yi is still very interesting, in line with the principle of sending the Buddha to his home, he also deliberately attached the information compiled by Nie Zhiyuan in his private letter to Xu Jie, and now these materials are on Xu Jie's desktop, and when Xu Jie saw something very close to the 122MM rocket launcher known as hail in later generations, Xu Jie also had to sigh about this unrecognizable history.

The picture is very simple, a 1.5-ton truck with 4 rows of 6 launch tubes on the body. The length of the launch tube is about 2 meters. THE STANDARD SHELL NEXT TO IT IS A 122MM TAILLESS ROCKET WITH A LENGTH OF ABOUT 0.8 METERS. After roughly browsing the relevant information, Xu Jie felt that this thing was at least much stronger than the BM13 Katyusha rocket launcher in history. It's more like a product of a combination of German rocket artillery and Russian rocket artillery. Absorb the advantages of all parties.

Speaking of the BM13 Katyusha rocket launcher in the former Soviet Union, I am afraid that most people know very well that the spectacular long surface and the large amount of projection in a short period of time when firing a salvo, coupled with the extremely simple launch device. This is probably how people feel when they see Katyusha rockets for the first time. This rocket launcher almost adheres to the advantages of the simplicity and practicality of Soviet-style weapons and the powerful projection volume, and is a pretty good artillery technical equipment in World War II. However, unlike history, this rocket does not have a practical tail wing, which makes Xu Jie feel a little strange.

In fact, under the historical conditions at that time, the use of the shell wing of the BM13 rocket launcher was a very correct choice, because the Soviet Union did not have enough production capacity and time to develop some overly complex equipment under strong pressure at that time. So the BM13 did not use a launch canister, let alone engrave rifling in it, but directly used the launch guide. In this way, the rotation of the rocket depends entirely on the rocket nozzle itself. The revs went down. Naturally, the accuracy will be reduced a bit. Historically, the Russians were in the interest of cost, and they thought it was a very cost-effective thing to reduce the complexity of the launcher by adding wings directly, so they chose rails and wings instead of launchers and rifling. Very good in terms of cost.

In the history of World War II, the real choice of complex turbine nozzles (and turbines on airplanes is not the same concept. Unlike the famous BM13, the German 2 rocket launcher gives the impression of obscurity, but it does not mean that the Germans have no good goods. Historically, the Germans also had several good rocket launchers, in terms of accuracy. The German rocket launchers, which used turborockets and launch tubes, were more accurate than the Soviet BM13, and in terms of range, they were okay. (Note: The German 2 War rocket launchers were also fired using rails.) ）

FOR EXAMPLE, GERMAN'S 15CM ROCKET LAUNCHER (NBFW41, 42 TYPES) CAN SHOOT A ROCKET WEIGHING 34.15 KG AT A DISTANCE OF 6,900 METERS, WHILE A 42 ROCKET LAUNCHER WITH A CALIBER OF 21CM CAN SHOOT A 112.6KG ROCKET AT A DISTANCE OF 7,850 METERS. In terms of range, it is shorter than the Katyusha's 8.5 km, but the accuracy is better than the latter. Sadly, however, this weapon was initially used by the Germans more as smoke grenades or special ammunition launchers than as a suppressive weapon, and after the Katyusha rocket artillery became popular, Germany still did not use this weapon as intensively as the Soviets. One of the reasons may be that the Germans considered the accuracy of rocket artillery to be too low. And it reloads slowly. But the Germans still had on-board rocket artillery. Some of the rocket artillery also earned the title of land Stuka. But in any case, the number of such weapons and the role they play cannot be compared with those of the Katyusha rocket launchers, although the German ones may be better in terms of technology and performance.

For the role of the 2nd war rocket artillery, Xu Jie's positioning is a cheap weapon that can tear apart the opponent's defense line or attack at a medium distance, in this era, there is almost no need for heavy rocket artillery with a long range, after all, in this era without advanced fire control, let alone guided artillery shells. The accuracy of long-barreled artillery at long distances will be relatively low, and this accuracy is only a quarter of the distance of the artillery, but it really can't hit anything! So the range at 15KM is already quite good. (Katyusha has a shell for BM13DD.) It is possible to play 11KM. So Xu Jie's requirement for this kind of artillery is more than 12KM.

AT THE SAME TIME, CONSIDERING THE DIFFICULTY OF LOADING, XU JIE BELIEVES THAT THE WEIGHT OF A SINGLE SHELL SHOULD NOT EXCEED 45KG, THAT IS, IT IS EQUIVALENT TO THE WEIGHT OF A 155MM SHELL. The purpose of this is to use the human state. IF YOU DO SOMETHING LIKE THE GERMANS TO MAKE AN 8-INCH ROCKET LAUNCHER WITH SHELLS WEIGHING 100+ KG, THEN JUST LOADING IS VERY PROBLEMATIC. And if the reload is slow, it will naturally lead to the efficiency problem of the rocket artillery, after all, the rocket artillery is only instantaneous firepower is very powerful, but when it comes to continuous suppression, it is better to wash and sleep. There is no advanced automatic reloading equipment for rocket artillery in this plane, and a large number of artillery shells are almost all manual.

And Nie Zhiyuan did a very good job in this regard, the caliber and bullet weight he chose coincided with the upper limit of manpower loading. And the weight of 24 launch tubes is not very heavy, and the average 1.5-ton truck can fully bear it. But there are also shortcomings, that is, the length of the shells is not enough, and although there is rifling to compensate for the accuracy of rocket artillery, it is still inappropriate to remove the tail fin. The solution to the problem in the Soviet Union after the end of World War II was to install four arc-shaped wings at the tail of the bullet, which were only attached to the shell before launch, and when launched, they were quickly opened to improve stability. At the same time, the center of gravity of the shell is set slightly forward to increase stability. Theoretically, it is not difficult to do this, but considering that it is a technical task to make the wings fit perfectly with the shell and the launcher, Xu Jie is not sure when this change will be made, and the other is how to make the rocket artillery shell longer, and the Soviets' approach is to roll out a rocket artillery shell like a rolled barrel, rather than cutting it. (This is what the author sees in the world of sea, land, air and space inertia, if you have any questions, don't look for me-!) ）

If it is a qiē shun lì, then this rocket artillery will eventually become a shrunken version of the BM21 Hail rocket launcher, although it cannot reach a range of more than 20KM due to charges and other technical problems, but in terms of accuracy and firepower, it will definitely throw off the historical German goods and Soviet goods. As for the role they play on the battlefield, it is definitely better than the historical rocket artillery, with a longer range, higher accuracy and more advanced territory that allows them to realize better.

"Since it is a simplified version of the BM21 rocket artillery in history, then let's call it a storm." In the end, Xu Jie, who came to the nature, also gave a special name to this rocket artillery, and asked the relevant departments to fully cooperate with the research and development of the rocket artillery, and take out samples in the shortest possible time.

Thanks to the book friend zhouyu1976, hukaikaka for the tip~~~. It's Friday again, and the subscription has been sluggish for the past week! The author has decided to add another chapter this afternoon, and I hope that all book friends can support me a lot! (To be continued......)
