The effect of printing books cannot be reflected in a short period of time. Let’s wait a few months to see if there is no way to attract foreign talents.

The important thing in front of me is still in the garrison.

It took about a month since the garrison troops returned to defense and rest and strengthened fortifications, and the Magic Weapons Research Institute finally took out a killing weapon.

Anti-aircraft gun!

Maybe the researcher is shy, and this cannon has no name, it is called Heavy Rain.

It is meaningless to use a single tube for anti-aircraft guns, because a single tube needs to be coordinated with near-explosive fuses and needs to be intensively deployed in actual air defense tasks, which is not suitable for mobile air defense operations. Moreover, now it is obvious that the combat goal is to attack various creatures, and there is no need to project a few kilograms of shells to smash them.

If used to shoot birds, anti-aircraft machine guns are enough. However, Wang Qi's people have a very abstract understanding of the demons. I don't know how strong it will appear later. Considering the influence of protection magic, the applicability of the machine gun is not high enough.

All that remains is multi-barrel anti-aircraft guns, with caliber choices between 20 and 30 mm.

The first type of rain is a 20mm quadron cannon, and the choice is also determined by processing capability.

In the entire system, the manufacturer with the highest processing accuracy is Xincheng Heavy Industry, but its positioning is not to make badges, receivers and other messy things, but to obtain high-precision processing equipment manufacturing and installation capabilities through self-replacement.

Military weapons have higher levels of confidentiality. Except for the artillery barrels that are temporarily manufactured by Xincheng Heavy Industry, the rest can only be produced in manufacturing bureaus with weaker physical processing capabilities.

If the processing capacity is lower, the reliability of parts such as the ammunition supply system with slightly complex mechanical structures will decrease significantly.

The manufacturing bureau affiliated to the research institute cannot create a mass-produced fast ammunition receiver with sufficient reliability, so it can only increase the number of gun barrels to balance the strike efficiency.

The rate of fire of the Torrential Rain Type is relatively slow. The four tubes combined together can only project nearly 300 warheads per minute.

However, some researchers have put in their hearts to design excellent functions.

When some of the barrels are damaged, this machine gun can be used to limit the current of magic through manual switches to ensure that the total number of bombs is not affected. It also has two removable parts, and two single-barrel rapid-fire guns can be removed to deal with situations where there are not so many air units that need to deal with.

To be honest, although the split looks pretty, it is a function that is exchanged for reliability.

Military weapons are first, and they are second to adapt to existing transportation systems, third to be easy to use, and fourth to portability. Reliability is the basis for the existence of weapons.

Fortunately, there is no system of car-mounted weapons now, and the cannons are mainly used on positions, and magic guns and cannons do not need to consider the impact of gunpowder explosion during shooting. It is not unacceptable to reduce the reliability of less permissions, and it will be improved in the future.

In terms of battery life, this cannon is equipped with two magic modules.

The large 50 kilograms can support the firing of 800 warheads. The small 5 kilograms are the energy source of the single-barrel gun after being split, and can support the firing of 100. They are usually placed on the gun as a battery, and can also be used for emergency shooting during the replacement of large modules.

It is not difficult to make the magic density higher. Even if it is eight thousand rounds, it is fine. However, pure magic may be detonated by some magic, so you have to be guarded against. Therefore, 80% of the weight in the large module is used to prevent dying, and the weight of the gem is less than 1%. On the contrary, the total amount of magic power of the small module is low, not that dangerous, and the proportion of gems is even larger.

The first type of rainstorm was used to try five units in the garrison, and by the way, Li Xiang went to take a look.

"The sound is so weird, everyone is all, everyone is like this." Li Xiang simulated the sound of cannons after he came back.

It's a bit strange, but Wang Qi doesn't care about the sound. As long as it's not the hushing sound, it's fine. He asked: "How high can the shells be hit?"

"I can't see clearly because it's too small. Anyway, the altitude of three or four thousand meters is still flying upwards."

That's similar to a real anti-aircraft gun, which shows that the institute has really understood the ballistic-related issues.

After a period of trial, the prototype was indeed not found any serious problems, so it only placed an order of 100 units.

One hundred units are distributed in the volcanic mountains where some fortifications are built, but they are not enough. However, this thing is much harder to build than a rifle. Without large-scale orders to support single production lines, one hundred units will take two months to complete. At that time, check the progress of the improved model and the changes in the north, and then decide whether to continue to increase the volume.

The follow-up will be left to the military to coordinate itself, and Wang Qi is preparing to push the appearance of the killer weapon.

Steam locomotive.

Wang Qi is not a big master with his own encyclopedia in his mind. He only knows the principle of the steam engine, knows what the steam locomotive that is still operating in the information age looks like, and does not know how to make the power of the train steam engine exceed 6,000 horsepower while controlling the total weight.

Now with experience in using and producing steam engines, we can also have a certain processing accuracy. There are even a few young engineers who have been in contact with steam engines for a long time. They are expected to push the steam engine power to more than one thousand horsepower, which is enough to transport nearly a thousand tons of cargo on the rails.

Not counting a strange thing with a curb weight of more than 500 tons to 6,000 horsepower, mass-produced locomotives of this level are the achievements of the development of steam locomotives for nearly a century. During this period, I don’t know how many people’s hard work and wisdom are gathered. It’s a bit outrageous to just get to the sky with just one step.

So at the beginning, as long as the entire front of the car can move and have a certain amount of traction.

In order to improve development efficiency and avoid detours, Wang Qi used his existing knowledge to draw a large anatomical picture of the steamed car head and some exploded drawings.

Even if he had seen steam locomotives visiting a museum, it was difficult to do such things alone. He didn't have to work hard on his own, but only focused on a few key points.

One is the combination of steam pipelines and boilers, which directly affects the steam volume and steam pressure produced by the locomotive, and has the greatest impact on power. Wang Qi also knows that steam must also be heated in the furnace to improve the heat utilization rate.

The second is the transmission structure of power output to the power wheel. At first, it was simply outputting the front and rear directions, but the reliability was low and the preparation work was large, so the longitudinal auxiliary output point was also increased. Of course, the actual mechanical kinetic energy provided by steam is still front and back, and it only provides up and down power through special mechanical joints. Wang Qi also studied steam equipment for a long time before he figured out what to do.

The third is the braking system.

In principle, trains should have unlimited road rights, which means that they deserve to die if they are blocked in front of the train, but there is magic in this world, which is more of the act of man-made damage to railways except for natural disasters and damage.

With the existing number of production departments, building a locomotive is not an easy task. In order to reduce the situation of derailment of the locomotive, braking is even a system that is more important than transmission.

What is embarrassing is that Wang Qi himself doesn't know how to brake. He only knows that the steam locomotive needs to brake with air and steam at the same time, and the relevant cylinders are at the front of the locomotive.

There is only one clue. It is impossible to launch a train braking system that is mature enough, so it can only be simplified.

But even if it is simplified, it is actually more complicated than the power steam furnace used by Xincheng Heavy Industry now, because it also involves steam-driven compressed air, floating valve hydraulic system, airlock-related pipeline layout methods, etc., including the whistle and sand-spreading mechanism are just small parts of this front air pressure system.

I spent two hours a day to do math problems and drawing, and it took nearly three months to produce more than 40 drawings, including separate configurations of several key systems, three views of dozens of important components, etc.

When he was so worried about the painting, he asked Li Xiang: "Can you understand?"

Li Xiangmeng shook his head: "It doesn't matter if I don't understand it, as long as someone can understand it."
