Chapter 1797: The distance of water and mountains are hard to push, and the secret of heaven is cast into a huge hammer

From this we can also know that after Qin Shihuang unified the six kingdoms, he promulgated the "cars on the same track" issue. When everyone read it in history books, they seemed to think it was nothing. However, this law was a major event that affected later generations.

So for Shen Mo, now, while ensuring the mobility of the troops, all firearm designs must obey this maneuverability standard, which is not surprising at all.

...

When Shen Mo heard the artillery design ideas that Tang Tianji reported to him, he couldn't help but nod.

To be honest, these children have good ideas, but due to lack of experience when designing weapons, there will be some mistakes of adding more water and adding more water to the surface, so that the weapon is designed more and more heavy.

Afterwards, Shen Mo introduced Tang Tianji and Yang Miaozhen. Because of his age, Yang Miaozhen is still a senior sister.

When it comes to ancient China, there were some unusual examples of the relationship between brothers and brothers, and of course most of them were first started.

However, there is also a saying that "there is no order of learning, and the best is the first". Even like the old monster of Stars, there is no situation where anyone who flatters better will become the senior brother.

Although Miss Yang Miaozhen was very late, her age was twenty-four years old this year. It was really inconvenient for her to call her senior brothers and sisters from the children of the sixteenth and seventeenth grade. So Shen Mo put the name of "Senior Sister" on Yang Miaozhen.

After they finished introducing the article, the generals of the Red Coat Army naturally surrounded this extremely powerful cannon and watched it in surprise.

When they saw such a thick cannon barrel and a pile of spherical iron cannonballs larger than human heads in the distance of the cannon. Each of those big guys weighed sixty or seventy pounds, these Red Jacket Generals were naturally shocked.

After that, Shen Mo and Tang Tianji chatted for a few words, telling him not to worry about his side and continue the test firing of the cannon.

Then Tang Tianji and his team adjusted the angle of the muzzle, checked the buffer device, and after loading the medicine bag, they put an extremely large flowering bullet into the cannon chamber.

Because of its extremely high ballistic trajectory, shells are often smashed from the sky. Solid bullets and shotguns are completely meaningless when used on this gun. Only flowering bullets can maximize their advantages in large caliber.

When Shen Mo was observing the cannon, he saw traces of fire in the cannon barrel. He knew that the cannon had undergone solid bomb test. In fact, the test fire of this cannon had reached the middle stage and can now fire the flowering bullet.

So, just after they avoided the tour group from afar, they saw the warriors of the gun group installing the cannon firing tube, and under the order of Tang Tianji, they pulled the cannon rope hard!

There was only a loud bang!

Everyone felt the land under their feet trembled. Around the fire of this mortar, the huge shock wave caused by the muzzle flames made the dust on the ground within more than ten meters of the cannon, and the dust on the ground was violently shaken, which was so exciting!

Shen Mo watched the cannon's shells come out of the chamber. At the 45-degree angle and the farthest shooting angle, the cannonball flew 15000 meters away, and then it suddenly hit the ground opposite the shooting range with a force of ten thousand pounds!

Then, there was a shocking explosion!

The explosion of the 40 kilograms of gunpowder loaded in the 78 kilograms of shells made everyone feel like they were in a huge bronze bell.

The vibrating air instantly made the people watching the test gun feel a powerful sound on their skin, and a hurricane hit their faces!

This is too fierce!

Yang Miaozhen and the others looked at the wooden dummies erected opposite the shooting range, as well as wooden shields and brick and stone walls used to test the power of shells, instantly flew towards all directions with the explosion point as the center!

These things were torn into tragic fragments at the moment the shell exploded!

At this time, Shen Mo was watching the state of the cannon stand.

At the same time as the shells were fired, the violent rear seat of the cannon made the gun stand make a heavy roar caused by metal impact.

The front wheel of this heavy mortar clearly jumped upward under the influence of torque, and then it began to rumble backward along the guide rails on the gun mount!

fine!

The spring buffer mechanism withstands the recoil of the shell. It seems that the students' calculations are not wrong, and the design is also very rigorous.

...But their thinking on developing weapons is a big problem!

After Shen Mo called Tang Tianji over, he pointed to the cannon and said, "Did you see this recoil?"

"See, teacher!" Tang Tianji blinked and said, "There is no problem with the cannon mount!"

"The gun mount is fine, but the foundation of the artillery is problematic!" Shen Mo heard this and said to Tang Tianji: "You can put it on a carriage and march. But have you calculated that how long does it take to start when you want to remove it until the artillery enters combat state?"

"Ah?" After hearing Shen Mo's words, Tang Tianji was stunned for a moment!

He really didn't expect that the time it took for the artillery to enter the launch state from the transportation process!

If we deduce it according to the teacher's words, it would take a long time to unload his four-ton artillery system in the carriage!

And the worst thing is that it cannot be launched in a carriage!

If the recoil of this gun just now is fired in the car, no matter what the carriage is, it will be broken in one shot.

After that, the mortar cannon completely became a "ground cannon". He could only fire the cannon on the spot, and he couldn't even go home!

At this time, Tang Tianji heard the teacher continue to say: "Because it is bent in trajectory, even if it is installed on a warship, the probability of hitting will be greatly reduced when attacking the opponent's ship... and the structure of all our warships cannot bear its recoil."

"It cannot be separated from the road. The carriage pulling the cannon cannot travel on any ground that is not solid. It cannot encounter rainy and snowy days, and it will be difficult to move forward when it encounters mud. What's more serious is that as long as it encounters a certain slope or mountainous area while marching, it will not be able to get through at all!"

"My God, what should I do?" At this time, when the fat little fat Tang Tianji heard the teacher's words, he immediately collapsed and said, pulling his hair:

"It's all useless to do it after such a lot of effort! This thing can be transported on the bus and fired. We tried our best to reduce its weight to four tons so that the carriage can be transported... But it can't get off the bus or climb the mountain!"
Chapter completed!
