"Talents!" Peng Yi was still very interesting. In line with the principle of sending Buddha to his home, he also specially attached the information compiled by Nie Zhiyuan to Xu Jie's private message, and now these information are placed on Xu Jie's desk.

, and when Xu Jie saw a 122mm rocket launcher that was very close to the 122mm rocket launcher known as Hail in later generations, Xu Jie had to lament this unrecognizable history.

The picture is very simple. A 1.5-ton truck has 4 rows of 6 launch tubes set up on the body. The length of the launch tube is about 2 meters. The standard artillery shell next to it is 122mm, about 0.8 meters long.

of tailless rockets. In

After browsing the relevant information, Xu Jie felt that this thing was much stronger than the historical BM13 Katyusha rocket launcher at least in terms of distance. It was more like a combination of German rocket launcher and Russian rocket launcher. It absorbed the ideas of all parties.

Advantages.

Speaking of the former Soviet Union's bm13 Katyusha rocket launcher, I'm afraid most people are very familiar with it. It has a spectacular long surface during salvo firing and a large projection volume in a short period of time, coupled with an extremely simple launcher. This is probably people's first

My feeling after seeing the Katyusha rocket launcher for the first time. This rocket launcher almost inherits the Soviet-style weapon "Top" and "Point" novels

With its simplicity, practicality and powerful projection, it was a very good artillery technical equipment in World War II. However, unlike history, this rocket did not have a practical tail wing, which made Xu Jie feel a little bit

strangeness.

In fact, under the historical conditions at the time, using the shell fins of the bm13 rocket launcher was a very correct choice, because the Soviet Union was facing strong pressure and did not have enough production capacity and time to develop some overly complex equipment. Therefore, the bm13 did not use launchers.

barrel, let alone engraving rifling on the inside, but directly use the launch rail. In this way, the rocket

The rotation of the missile depends entirely on the rocket nozzle itself. As the rotation speed decreases, the accuracy will naturally decrease. Historically, the Russians considered cost considerations and believed that it was very important to directly add missile wings to reduce the complexity of the launcher.

It's a cost-effective thing, so they chose rails and wings instead of launch tubes and rifling. In terms of cost, it's very good.

In the history of World War II, the country that really chose complex turbine nozzles (which are not the same concept as turbines on airplanes.) and launch tubes and internal rifling was Germany. Unlike the famous bm13, the German rocket launcher in World War II gave people

It feels unknown, but that doesn’t mean the Germans are

There are no good products. The Germans have had several good rocket launchers in history. In terms of accuracy, the German rocket launchers that use turbo rockets and launch tubes are more accurate than the Soviet bm13, and they are acceptable in terms of range. (Remarks

:German World War II rocket launchers also used guide rails.)

For example, Germany's 15cm rocket launcher (nbfw41, 42 type) can launch a rocket weighing 34.15 kg to a distance of 6900 meters, while the 42 type rocket launcher with a caliber of 21cm can launch a 112.6kg rocket.

It shoots out to 7850 meters. In terms of range, it is shorter than the Katyusha's 8.5 kilometers, but its accuracy is better than the latter. But the sad thing is that this weapon was initially used more as a smoke grenade or special ammunition in the hands of the Germans.

transmitter instead of when

It has become a suppressive weapon. After the Katyusha rocket launcher became popular, Germany still did not use this weapon as intensively as the Soviets did. One of the reasons may be that the Germans believed that the accuracy of the rocket launcher was too low and the loading was slow. But the Germans still

There are vehicle-mounted rocket launchers. Some rocket launchers have also won the title of Land Stuka. But no matter what, the number and role of this weapon cannot be compared with the Katyusha rocket launcher, although the German product may be better in terms of technology and performance.

Better.

Regarding the role of rocket launchers in World War 2, 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 launchers with too long range. After all, there is no such thing as

In the era of advanced fire control, not to mention guided artillery shells, long-barreled artillery can be used at long distances.

The accuracy will be relatively low. This kind of accuracy is only a quarter of the artillery. If the distance is far away, you really can't hit anything! So the range is already quite good at 15km. (Katyusha has a bm13dd artillery shell.

It can hit 11km.) So Xu Jie’s requirement for this kind of artillery is that it can hit 12km or more.

At the same time, taking into account the difficulty of loading, Xu Jie believes that the weight of a single artillery shell should not exceed 45kg, which is equivalent to the weight of a 155mm artillery shell. The purpose of this is to use manpower. If you do it like the Germans

For an 8-inch rocket launcher with shells weighing 100+kg, then

Reloading alone is very problematic. Slow reloading will naturally lead to problems with the efficiency of the rocket launcher. After all, the rocket launcher is only very powerful in terms of instantaneous firepower, but when it comes to sustained suppression, it is still a waste of time. There are no advanced ones in this plane.

Rocket launcher automatic loading equipment, a large number of artillery shells are almost all manually loaded.

Nie Zhiyuan did a very good job in this regard. The caliber and bomb weight he chose coincided with the upper limit of manual loading. Moreover, the weight of 24 launch tubes is not very heavy, and an ordinary 1.5-ton truck can fully bear it. But it is not enough.

There are also some, that is, the length of the cannonball is not enough, and

And although there is rifling to make up for the rocket launcher's accuracy problem, it is still inappropriate to remove the tail fin. The Soviet Union's solution to the problem after World War II was to install four arc-shaped fins on the tail of the rocket, which only interacted with the artillery shell before launching.

They fit together and when launched, open quickly to improve stability.

At the same time, the center of gravity of the artillery shell is set slightly forward to increase stability. In theory, this is not difficult, but it is a technical task to consider whether the wings of the artillery shell and the launch tube can fit together perfectly.

, so Xu Jie is not sure when this change will be made, and the other

The key is how to make the rocket launcher shell longer, and what the Soviets did was to roll out a rocket launcher shell similar to rolling a gun barrel, rather than cutting it out. (This is what the author saw in the world of sea, land, air and space inertia.

If you have any questions, don’t come to me--!)

If all goes well, this rocket launcher will eventually become a reduced version of the bm21 hailstone rocket launcher. Although it cannot reach a range of more than 20km due to charging and other technical problems, it will definitely leave behind the historical ones in terms of accuracy and firepower.

German goods and Soviet goods are two different things. As for their role on the battlefield, they are definitely better than rocket launchers in history. Their longer range, higher accuracy, and more advanced territory are enough to make them better monetized.

"Since it is a simplified version of the historical bm21 rocket launcher, let's call it Storm." Xu Jie, who finally came to his senses, also gave this rocket launcher a name, and asked relevant departments to fully cooperate with the rocket launcher's research and development work in the shortest possible time.
