Yi Wan Feng, but was hyped by Ming fans to become the legendary artifact of Katyusha in the Ming Dynasty. But Malin did not agree, mainly because he had read an issue of "The Great Reveal of Ancient Weapons", which mentioned above that Yi Wan Feng Feng was unstable. Mainly, it started to fly randomly after more than 45 meters, which was comparable to the lead bullets of the smoothbore gun.

Therefore, although the sound is huge when launching, if the distance is too far, the effect is often not good. Even at a close distance of 45 meters, the probability of the dummy team being hit in the show is only 90%. If it exceeds 100 meters, the hit rate will be very low.

Moreover, the program said that in the "Jingnan Campaign", Zhu Yunwen's Ming army used a swarm of cavalry of Zhu Di, the Ming Chengzu. Zhu Di, who personally led the charge, was almost hit, but because of his poor hit rate, Zhu Di escaped.

Later, because the cost and benefits were not proportional, the Ming Dynasty gradually gave up a swarm of bees. However, multi-tube and multi-level firearms such as "Divine Fire Flying Crow" and "Fire Dragon Out of Water" had good results. However, multi-tube firearms also have disadvantages. If the ignition time of the two booster launchers on the left and right is different, and only one side ignites first, this thing will be folded back and hurt your own people.

The problem of a swarm is also very big. The main reason is that the gunpowder cartridge of the "Shen Ji Arrow" used by a swarm is tied to the side of the arrow. In this way, the center of gravity is tilted. Moreover, as the gunpowder in the cartridge is burning and consumed, the mass of the cartridge becomes lighter and lighter, and the overall center of gravity of the Shen Ji Arrow does not change. If this change is vertical, it will not affect the direction. But this change is horizontal. If the center of gravity changes horizontally, it will be strange if the Divine Ji Arrow does not fly randomly.

Therefore, after the magical machine arrow left the launch box, the distance between thirty or forty meters in front can still maintain the direction due to inertia. However, after this distance, it is easy to fly randomly due to the lateral change of the center of gravity.

When Marin watched that show in his previous life, he saw a swarm of bees in the test with his own eyes. After the magical machine arrow was launched, it directly carried to the earth at a distance of 30 or 40 meters, and jumped on the ground.

The best solution is actually very simple, which is to hollow out the tail of the bow and arrow and put it in gunpowder. In this way, even if the weight of the tail is reduced after the gunpowder is burned, the center of gravity changes longitudinally along the arrow body and will not affect the flight direction.

But Marin dared not do this, why? Because it is easy to imitate this thing. It is so easy to hollow out the tail of the arrow, and it can be easily seen. If someone else learns it, he can directly attack the Beihai Army.

Therefore, Marin would rather not build it than other countries to learn how to make such a killer weapon.

As for the rush in front of you, to be honest, Marin was not very interested. However, he was not completely uninterested.

Why? People in the Ming Dynasty did not understand how to use it. In fact, if you use it well, it would be very useful. Tests of the TV program I watched in the previous life showed that at a distance of 45 meters, the hit rate of a swarm could reach 90%. Moreover, the penetration power was very strong, and the plastic dummy was directly penetrated, which showed that it was very powerful.

Therefore, using a swarm of bees, you can learn from the later lobster soldiers and endure it. After the enemy enters within 45 meters, they will launch them in a concentrated manner and directly penetrate the opponent. If you shoot with your face, it will be even more powerful, and it is estimated that the one who runs through it will not be the only one who runs through it.

Moreover, the first thing the Beihai Kingdom battle formation focused on was defense. With a defensive formation arranged by wheeled chariots, the enemy's cavalry could not break through the defense line of the Beihai Kingdom army for a while. Therefore, the Beihai Kingdom army had the confidence to put the enemy within 45 meters and then launch it in a concentrated manner.

The reason why the Ming army abandoned the swarm was that the Ming army used firearms very irregularly. For example, the musketeers had a very low hit rate of 100 steps, but after seeing the enemy charge, they were easily released from a distance. As a result, they were all empty guns. It took a long time to load ammunition, and the cavalry on the opposite side had already rushed over and chopped people.

Therefore, the fact that the Ming army was abandoned by the rush was not only due to the fact that there were certain problems in itself, the Ming army's own poor quality was also an important reason.

...

However, Marin was not very happy to use the original version of the buzzer. Because the range of the buzzer was too close. When shooting, it was even worse than the archers' rain of arrows on the opposite side. For example, shooting against a team of English longbowmen was a delivery person.

If the opponent knows kite tactics and always keeps a certain distance, he will definitely be abused. The wheeled chariot in front of the Beihai Kingdom has good defense, but it also affects the mobility. The opponent retreats and can't catch up even if he wants to.

Therefore, the "great inventor" Marin intends to use the physics knowledge at the high school level in later generations to transform the swarm to obtain a longer effective range.

How to increase the range? Naturally, it is to improve its flight stability. How to make its flight more stable? The first is to adjust the center of gravity, and try to make the center of gravity on the arrow, rather than between the cartridge and the arrow body. However, the structure of the magic machine arrow itself, which binds the cartridge, is destined to be difficult to adjust the center of gravity perfectly. Therefore, Marin can only say that he can adjust it as much as possible.

For example, Marin can tie a counterweight of the cartridge opposite the cartridge. But the problem is that after the gunpowder in the cartridge is burning, it becomes lighter and lighter, and the weight of the counterweight will not be reduced. Therefore, the center of gravity will eventually become unbalanced.

But Marin didn't expect a complete balance. What he wanted was to let the divine machine arrows fired from swarms fly as smoothly as possible for a longer distance. After all, if the divine machine arrows do not fly randomly, their theoretical range can reach three or four hundred meters.

Marin didn't even think about letting the Divine Arrow fly 300 to 400 meters smoothly. If the Divine Arrow can fly 500 meters smoothly, he would be satisfied.

How to make the Divine Machine Arrow fly more smoothly? Marin's second idea is to "equip" the Divine Machine Arrow. That is, aircraft similar to later generations, and to install a pair of wings for the Divine Machine Arrow.

Although wings cannot guarantee that they can fly 300 or 400 meters smoothly, it is enough to ensure that hundreds of meters of flights are stable.

This chapter is not finished yet, please click on the next page to continue reading the exciting content later! Moreover, from the perspective of weapons, if the flight is too smooth and the ballistics are too straight, the "flying" will lose its value!

Why do you say that? A swarm is actually a weapon of range strikes, with wide coverage. If you strike against enemy groups, the trajectory is too straight. This small 32 magical arrows will only shoot a soldier on the opposite side into a hornet's nest. It would be too unprofitable to kill an enemy with 32 arrows. Therefore, the magical arrows in a swarm require a certain amount of offset, rather than all precise strikes.

Therefore, the method of Marin delaying the time of the divine arrow's deviation is very good. No matter how cheap it is over 100 meters, or if it is a small price at a distance of 100 meters, it is the most military value.

...

Therefore, Marin changed the cylindrical cartridge of the magic machine arrow in a swarm into a rectangular cartridge. Then, on the other side of the corresponding rod of the cartridge, a pair of wooden wings were nailed. The wings were very simple, which was a rectangular wooden board with the middle part nailed to the rod and corresponding to the cartridge.

In addition, considering the launch of the magical arrow, it is similar to the launch of the space shuttle. That is, the space shuttle itself sprays flames, and the rocket body only provides fuel. Therefore, Marin also nailed a rectangular wood chip to the rectangular cartridge as a "wing".

However, the wing wood chips opposite the cartridge will be larger and heavier. Because this wood chip has a certain counterweight function. The wood chips nailed on the cartridge are very light and thin, mainly serving as the "space shuttle wing" of the cartridge.

Moreover, because the two wood chip wings are parallel, there are wood chips supported on the top and bottom when loading, and it is easier to maintain a stable state.

Then there is the tail feather of the arrow. Marin deliberately soaks it in the mud to contaminate the mud. After drying, it will harden. However, when it is fired, it will not be easily burned by the tail flame sprayed by the cartridge.

Many times, the original version of the magic arrow burned the tail feathers because the tail flame of the cartridge burned the magic arrow, causing the body of the magic arrow to lose balance and then flew around. Marin's method of slurrying (mud) is also very good.

Although we have two pairs of wings, it is better to keep the tail wing. After all, modern aircraft also retain the tail wing. Marin is not an aircraft expert, but he also knows how to copy homework.

Moreover, Marin specially sets the direction of the tail feather parallel to the wings of the wood chip. When installing, it is also installed in parallel. In this way, it is difficult to offset in the longitudinal direction when the magic arrow flies. The so-called longitudinal direction, because it is flat, naturally refers to the up and down direction.

As for the horizontal deviation, it is exactly what a swarm needs. Because to achieve a range strike, the Divine Arrow must be dispersed. Otherwise, staring at a target to shoot is too wasteful. Therefore, Marin did not add a vertical tail to the tail of the arrow. Because the vertical tail will prevent the Divine Arrow from lateral deviation.

In addition, in order to maintain the penetration of the magic arrows and achieve secondary killing, Marin deliberately let someone saw the wooden wings out of dents, leaving only a small part of them connected.

In this way, when the arrow penetrates the enemy, the wooden wings will be hit and will easily break due to the sawed dents, so that the arrow body can penetrate the target, and even hit the next enemy, causing more casualties to the enemy.

...

After the design was completed, Marin asked Ke Laowu to bring a few craftsmen from Beihai Kingdom to modify according to Marin's idea. Because two pairs of wooden wings were added, the divine machine arrows became much wider. As a result, the number of each cylindrical arrows was greatly reduced. In order to accommodate the wings, the partition could not only leave round holes, but also larger and wider square holes to install and fix the improved divine machine arrows.

But after doing this, the original wooden tube was not suitable for use. For this reason, Marin specially created a wider wooden tube, and the number of layers of the magic machine arrows was reduced to three rows. In this way, a total of three rows, with a new type of widened version of 8 arrows in each row appeared in a swarm.

After testing, this magical arrow indeed met Marin's expectations. It still did not run up and down at a distance of 150 meters, maintaining strong lethality.

But considering that this new type of magical arrows began to disperse at a horizontal distance of 120 meters. Therefore, the optimal strike distance is actually about 120 meters. If it is far away, the horizontal distance between the arrows is too large to achieve the effect of saturation strike. If it is close, the magical arrows have not dispersed horizontally, and they are too saturated to achieve range strikes.
