"Talent!" Peng Yi is still very interesting, in line with the principle of sending Buddha to 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 rocket launcher called 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 artillery shell next to it is a tailless rocket about 0.8 meters long. 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 an extremely simple launch device. This is probably how people feel when they see Katyusha rockets for the first time. This rocket launcher almost inherits the advantages of the simplicity and practicality of Soviet-style weapons and the powerful projection...... In 2 battles it was a pretty good artillery technical equipment. 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 engage in some overly complex equipment in the face of strong pressure, so the BM13 did not use a launch canister, let alone engrave rifling in it, but directly used the launch rail. In this way, the rotation of the rocket depends entirely on the rocket nozzle itself. When the speed goes down, the accuracy will naturally decrease a little. And historically, the Russians were in the consideration of costs. They decided that it would be cost-effective to add wings directly to reduce the complexity of the launcher, so they opted for rails and wings instead of canisters 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. And the country with the launch tube, as well as the internal rifling, is Germany. Unlike the famous BM13. The German 2 battle rocket artillery gives people the feeling of obscurity, but it does not mean that the Germans do not have good goods. Historically, the Germans also had several good rocket launchers. In terms of accuracy, the German rocket launchers with turborockets and launch tubes are more accurate than the Soviet BM13, and in terms of range, they are okay. (Note: The German 2 War rocket launchers were also fired using rails.) ）。 …。

For example, Germany's 15M rocket launcher (NBF41, 42) can shoot a rocket weighing 34.15 kg at a distance of 6,900 meters, while a 42-type rocket launcher with a caliber of 21M can hit a 112.6kg rocket at 7,850 meters, which is shorter than Katyusha's 8.5 kilometers in terms of range, but the accuracy is better than the latter. Sadly, however, in the hands of the Germans, this weapon was initially used more as smoke grenades or special ammunition launchers than as a suppressive weapon. After the popularity of Katyusha rocket artillery, 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 vehicle-mounted rocket artillery, and some of them 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 2 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. This kind of accuracy is only a quarter of the artillery, and the east-east distance is far away, but it really can't hit anything! So the range at 15km is already quite good. (Katyusha has a BM13DD shell that can hit 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, the weight of a shell. The purpose of this is to use the human state. If you do the Germans with an 8-inch rocket launcher with shells weighing 100+ kg, then just reloading is a problem. 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 has done a very good job in this regard...... The caliber and weight he chose coincided with the upper limit of manpower reloading. 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. The solution to the problem in the Soviet Union after the end of World War II was to install 4 arc-shaped wings in the tail of the war. It is only attached to the shell before it is fired, and when it is fired. Quickly open for improved stability. At the same time, the center of gravity of the shell is set slightly forward to increase stability. Theoretically, this is not difficult, but considering that it is a technical task to be able to make the wings fit perfectly with the shell and the launcher. So Xu Jie wasn't sure when this change would come out, and the other was how to make the rocket artillery shell longer, and the Soviets' approach was to roll out a rocket artillery shell like a rolled barrel, rather than cutting it out. (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 all goes well, the rocket launcher will eventually become a scaled-down version of the BM21 Hailstone, although it will not be able to reach a range of more than 20 km due to charges and other technical problems. But in terms of accuracy and firepower, it will definitely throw off the two streets of German goods and Soviet goods in history. As for the role they play on the battlefield, they are certainly better than the historical rocket artillery, and the longer range, higher accuracy, and more advanced territory are enough to make them realize better.

"Since it is a simplified version of the historical BM21 rocket launcher, 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).
