Chapter 156: Carriage

Shangwen stayed up all night, wiped his face casually to eat something, and went to the arsenal. There are many things to do in a day. Mainly, the improvement work of the steam engine needs to be further carried out. This is a very important core.

At the gate of the arsenal, Shangwen saw bullock carts from the north. These bullock carts are all two-wheeled carts. Use one or two cows to pull. It was these bullock carts that ensured the logistics supplies for hundreds of thousands of Qin army soldiers. The load capacity of bullock carts is generally very large, which is a serious overload situation. These ox carts are all iron and coal transported from the north. These are important raw materials for making guns. Especially coal. The furnace temperature is greatly increased.

Shangwen gave way to the bullock cart. Looking at the bullock carts. Pulling heavy coal and iron ingots. Shang Wen felt that a four-wheeled carriage should be developed. Because the current conditions are basically met, and with the expansion of the scale of the war. Cars that require a larger load capacity are also proposed sooner or later.

These conditions include horses. Da Qin acquired a large number of horses in the war against the North. In addition to these horses equipped with a large number of cavalry, there are still a large number of horses that are not used.

The speed of cattle is much slower. The speed of horses is higher than that of cattle. As the pace of war accelerates, the army urgently needs a vehicle that can be quickly and massively supplied, such as artillery shells. Musket. There are bullets. These all require fast supplies. If the supply is still the same as before, the situation will suddenly become very bad. Logistics will fall into a disaster situation.

There is another important reason. With the improvement of road conditions, as Daqin acquired a large number of prisoners of war, these prisoners of war built highways and highways on a large scale. Qin's road conditions have been greatly improved. In the case of road upgrades, if you continue to use the original means of transportation, it will appear very untimely. And the artillery also needs a new type of carriage for traction.

Future wars will basically be highly mobile operations. Everything at the moment must be changed. Therefore, the four-wheeled carriage appeared. It should be.

Looking at the wooden wheels, Shang Wen believes that the use of iron frame wheels is also necessary. Because, after the train was born, if the wooden wheel is used again. What happened, Shang Wen didn't need to think about what happened. Wheels that continue to rotate at high speeds produce huge friction. Under the wheels without bearings. Only broken. Then it caused the entire train to derail.

The emergence of the four-wheeled carriage is undoubtedly a technical preparation for the train carriage. Thinking of this, Shang Wen took out his notebook and roughly drew the structure of the carriage. In addition, a pair of steering structure is attached. In fact, it's just a moving shaft between the next round and the previous round. These do not need to be clearly pointed out, those craftsmen with extraordinary creativity can also do it.

Shang Wen closed his notebook and entered the arsenal. Shang Wen first handed some of the drawings he drew yesterday to the R&D team, and then some musical instruments. Shangwen needs to be made by hand. At present, it can only be made by hand. When Shangwen gave a lot of drawings to the craftsmen, the craftsmen were very surprised.

They are not surprised by the musical instruments. It's the difficulty of processing. Because of the French horn, the overall structure is more complicated, and the trombone is okay. Shang Wen pointed out that it can be processed separately. In fact, they are processed separately. The prerequisite is to ensure that the final can be tightly connected together.

The craftsmen with small hammers immediately set about building. Shangwen saw that he had nothing to do with him, so he went to look at other things. The four-wheeled carriage is all left to the craftsmen to handle. I can't ask about the rest of the matter. Must adopt this kind of entrusted free management. Can mobilize the enthusiasm of craftsmen to a great extent. If you do everything, you will be exhausted. Don't worry about other things.

Now that he is in a certain position, he is thinking about the whole thing. Rather than a specific individual.

Shangwen first checked the work of the steam engine, and a large number of craftsmen were debugging and installing the equipment. It is estimated that they are doing tests. What they are going to do this time is a two-wheel steam engine. Instead of just making a one-way steam engine. The efficiency is more than twice that of the original steam engine. The working principle is also different. After this kind of steam engine, Shang Wen felt that a figure eight steam turbine should be given. This kind of steam turbine is more efficient, but the processing technology. It depends on the situation.

Shang Wen turned and left. The production of muskets is on the right track. At present, it has been able to produce two hundred muskets a day, which is already the maximum load. The craftsmen work in three shifts. Moreover, the barrel has not yet been formed using drilling technology. In the process of research and development. This output is already very high.

The pouring work of the artillery progressed very quickly. Fifteen five-inch guns can be manufactured in one day, which is an amazing number. And while pouring artillery, a large number of bullets and shells can be poured. This is due to the large-scale use of iron molds. Moreover, this number is still likely to appreciate because a larger blast furnace is under construction and will be put into production on a large scale soon.

The production of small-caliber artillery has been discontinued. And the effect of a five-inch cannon is more lethal than a two-inch cannon. The maximum range can reach four miles. And can launch a variety of ammunition. Shangwen still increases the various tests of the artillery. The artillery produced requires a large-scale and rapid installation of the Qin army. Because the training has already begun. The artillery squad members of those guns have been scattered among the various units. Due to the lack of weapons, it is difficult for them to accept the current training. Therefore, the demand for equipment is very large.

And this equipment gap is still very large. The Qin Army needs to be equipped with at least 300,000 muskets and more than 300 artillery pieces. In addition to the future needs of the six countries, the arsenal was operating overnight and could not meet such a large demand. Faced with such a big demand. Either expand production. Either improve the technology. Expanding production is currently the only solution that can be solved.

After seeing that the production of guns and artillery was recorded in his notebook, Shang Wen began to transfer to the bullet and artillery production workshop. The security work has been done very well. At the very least, no open flame was found in the filling room. Moreover, the number of people is not very large, and the space is huge. There are many escape exits to facilitate the rapid evacuation of personnel. This is well done.

As soon as Shangwen came out of the workshop, he ran into female workers holding three pairs of boots. It seems that they made three pairs of boots overnight. Because the three styles of boots are different. There are boots. Paratrooper boots, the style of Martin boots that are usually worn. These are provided by Shangwen. However, Shang Wen took a look at the sole and was a little unhappy.

Because they still use straight soles, there is no distinction between left and right feet. And there is no spiked heel.
