The earliest 7.62*54mm bullets were round-headed, flat-bottomed, lead-core, and white copper armor, but this time the Russians came up with a new type of pointed bullet, and there is also a bullet with a steel core in these pointed bullets, although the export kinetic energy is about the same, and the weight of the warhead is about the same, but the armor-piercing power has obviously been improved to a certain extent. Pen "Fun" Pavilion www.biquge.info (This is a steel-core pointed bullet that only appeared after 1908 in history.) And for such high-powered bullets, the level of defense of armored vehicles should naturally be improved.

And in order to withstand the medium and close range attacks of such bullets, the Bavarian side needs to increase the thickness of the armor from 5mm to about 7mm! This, naturally, significantly increased the weight of the armor, and the entire vehicle needed to be redesigned and arranged. Unless you can bring the weight down in other ways!

The Russians thought about it, and then they came up with a new idea, and they decided to use a lighter machine gun for the original transporter site for the adoption of two weapon configurations. Specially designed tank turf, on the other hand, used heavier guns. And for the Russians, Bavaria said that there is no problem!

In order to reduce the weight as much as possible, it is naturally impossible to equip an independent turret, so from the appearance point of view, this simple machine gun combat vehicle is actually not much different from the machine gun pickup of later generations, but because of a certain amount of armor protection, the front of the hull can completely resist the attack of machine guns and rifle bullets at a distance of 100 meters, and the thickness of the side steel plate is also about 4mm.

The Russians insisted on using their own machine guns, and Bavaria apparently did not intend to supply the Russians with new machine guns with their own replaceable barrels. Therefore, the machine gun used in this vehicle is still the relatively old Maxim machine gun. It was still equipped with larger buckets, but the Germans made some improvements in the details.

In order to ensure the continuity of fire and a sufficient rate of fire, the Germans specially designed a double-type gun mount, which can accommodate two machine guns, and the lower part is also equipped with an auxiliary rotating device, which can control the pitch angle and rotation more quickly, and the biggest change is that a set of optical sights is installed in the middle of the two machine guns, which can assist in ranging and aiming.

The Germans also improved the gun body, because there was no need to consider the manual movement of the machine gun, so the weight could be increased in many places to improve performance, and the Germans first added an armor sleeve to the front of the bucket of the machine gun to prevent the machine gun tank from being hit by bullets and causing failure. On the front of the machine gunner. A large detachable shield was also added to protect the Heavy.

In order to increase the persistence of the machine-gun's fire. The Germans had not yet devised a new cooling water system, which was more complex than the machine guns used by the infantry. After the cooling water pumped from the cold water tank enters the cooling water, it takes heat from the barrel of the machine gun along the annular pipe. It is then cooled close to the muzzle, and the water vapor turns into water and flows back down another conduit into the cooling tank. This setup does not require a special addition of water to the machine gun cooling bucket to allow continuous firing.

However, the Bavarians, who thought they were perfect for shooting, were not popular with the Russians, because they thought that if the war was to start in winter, they did not need cooling water at all, so they only purchased a few spare sets, which the Bavarian side did not expect.

During the Boer War, the 37mm pin-pin cannon invented by Maxim was highly praised by both Britain and Burkin, because of its fierce firepower and light weight, so the Russians also decided to equip this machine gun as a light artillery for cavalry. When the Russians discovered that this new vehicle had a good spacing and a huge loading capacity, they came up with the idea of putting this weapon on a combat vehicle.

The 1-pounder rapid-fire gun (another word for the pin-pin gun) was not as easy to serve as a machine gun, and this weapon was actually used as a light infantry gun with wheels in the armies of various countries. The weight of the gun is 186 kg, the length of the gun is 187 cm. Next to it is a 25-round ammunition box. The shell used weighs 1 pound and the ammunition specification is 37mm*94mm. This cannon can easily project 300 shells to a distance of 4,500 yards in a minute! What does this mean? In addition to showing that it is theoretically possible to drop 400 pounds of ammunition on top of the opponent's head in one minute, it also means that one minute of continuous design can knock out 90 pounds worth of ammunition!

(One shell 6 shilling.) Of course, in actual combat, it is rare to shoot hundreds of shells with a single pull of the trigger, usually 25 rounds of ammunition chain, and the first shell is used for correction. Then the remaining 24 shells were emptied at once. Instantaneously cover the target area in a short period of time. ）

"I'll rub it, this one is not easy to get!" When the Bavarian technicians got the request of the Russian side, they first said that it was not easy to do, for the simple reason that this thing is actually an enlarged version of the Maxim machine gun! A cooling bucket that can hold at least 15kg of water is required. The weight of the entire gun is already as high as 186kg, and there is a huge bullet disc next to it, which adds up to more than 200 kg, and it is a little more difficult for such a heavy gun to quickly rotate and pitch simply by human hands.

Therefore, in history, except for those goods added to the wheels of land guns as light guns, most of the 1-pounder guns used a gun carriage similar to that of later anti-aircraft guns, and even added a pillar above the barrel obliquely, and the huge cooling bucket of this 37mm gun was tied with an iron ring under the pillar.

In fact, Bavaria used a similar artillery mount. (You can see the wiki for details, and you can also look at the pitch and rotation system of the ** 37 anti-aircraft gun.) But unlike in history, Bavarian engineers considered abandoning cooling buckets, which, first of all, were not very necessary in the eyes of the Russians. After all, with the Russians, such shells could not have been designed as much as machine guns, and the requirements for fire continuity were not high.

Secondly, the requirements for cooling water for artillery are a little too much, almost more than three times the requirements of machine guns! Moreover, this is a cannonball, the amount of cooling water must be huge, and the vehicle is already limited, and the Russians and Bavarian engineers have been struggling with the problem of shells and the amount of cooling water. (Don't think that a machine gun with 5kg of water is enough, that is going to cause an accident, there is a machine gun in actual combat, and a company of people sends water with a kettle.......) ）

Eventually, Bavaria's proposal was to replace the cooling water with heavy fins and to lower the rate of fire from 300 rounds per minute to around 180 rounds per minute. This ensures that the gun will not overheat when using a 25-round drum.

The second is a ....... (To be continued.) )
