Chapter 485: Foreign trade version armored vehicle
The earliest 7.62*54mm bullets were round-headed, flat-bottomed, lead-cored, and cupronickel quilt, but this time the Russians came up with new-style pointed bullets, and among these pointed bullets, there is another bullet with a steel core. Although the export kinetic energy is similar, and the weight of the warhead is similar, the armor-piercing power is obviously improved. (This historically is a steel-core pointed bullet that only appeared after 1908.) For this powerful bullet, the level of defense against armored vehicles must naturally be improved.
In order to withstand the mid-to-close range attacks of this bullet, Bavaria needs to increase the armor thickness from 5mm to about 7mm! This naturally greatly increases the weight of the armor, and the entire vehicle needs to be redesigned and arranged. Unless you can reduce the weight in other ways!
The Russians thought for a while, and put forward a new opinion. They decided to use two weapon configurations, and the original transporter site uses a lighter machine gun. The specially designed tank site uses heavier artillery. For the Russians, Bavaria says it’s 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, this kind of compact machine gun chariot is actually not much different from later machine gun pickups, but because of the certain armor protection, the car The front of the body can fully resist 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 clearly did not intend to provide the Russians with its new machine guns with replaceable barrels. Therefore, the machine gun used in this tank is still the older Maxim machine gun. It is still equipped with a larger bucket, but the Germans have made some improvements in details.
In order to ensure the continuity of firepower and a sufficient rate of fire, the Germans specially designed a dual-type gun rack, which can accommodate two machine guns, and an auxiliary rotating device at the bottom, which can control the pitch more quickly. Angle and rotation, and the biggest change is the installation of an optical sight between the two machine guns, which can assist in ranging and aiming.
The Germans also made improvements on the gun body. Because there is no need to consider the manual movement of the machine gun, it is possible to increase the weight in many places to improve performance. The Germans first installed an armor sleeve on the front of the machine gun barrel to prevent the machine gun. The water tank failed after being hit by a bullet. In front of the gunner. A huge detachable shield was also installed to protect the machine gunner.
In order to improve the continuity of the machine gun firepower. The Germans have not yet designed a new cooling water system, which is more complicated than the machine guns used by infantrymen. After the cooling water drawn from the cold water tank enters the cooling water, the heat is taken away from the barrel of the machine gun along the circular pipe. Then it cools near the muzzle, the water vapor turns into water and then flows back into the cooling water tank along another pipe. With this setting, you can shoot continuously without adding water to the machine gun cooling bucket.
However, the Bavarians who thought they were perfect shooting were not welcomed by the Russians, because they believed that if the war started in winter, cooling water was not needed at all, so they only purchased a few spare sets, which gave the Bavarian a start. Missed.
During the Boer War, the 37mmpin-pin gun invented by Maxim in the Boer War was highly praised by both the British and the British because of its fierce firepower and lighter weight. Therefore, the Russians also decided to equip this machine gun as a light artillery for cavalry. When the Russians discovered that this new vehicle had good passability and huge loading capacity, the idea of putting this weapon on the tank was born.
The 1-pounder rapid-fire gun (another term for pin-pin guns) is not as easy to serve as machine guns. This weapon is actually used as a light infantry gun in the armies of various countries with wheels. The body weight is 186 kg and the length of the body is 187 cm. A 25-round ammunition box is next to it. The weight of the shell used is 1 pound, and the ammunition specification is 37mm*94mm. This artillery can easily project 300 shells to a distance of 4,500 yards in one minute! what does this mean? In addition to showing that 400 pounds of ammunition can theoretically be thrown on top of the opponent's head in one minute, it also means that one minute of continuous design can knock out ammunition worth 90 pounds!
(One shell is 6 shillings. Of course, in actual combat, hundreds of shells are rarely fired with a single pull of the trigger, usually 25 rounds, and the first shell is used for correction. Then the remaining 24 shells Light up. Cover the target area in a short time.)
"I wipe it, this is not easy!" When the Bavarian technicians got the request from the Russian side, they first said that it was difficult to handle. The reason is simple. This thing is actually an enlarged version of the Maxim machine gun! A cooling water bucket that can hold at least 15 kg of water is required. The weight of the entire artillery is as high as 186kg, and there is a huge ammunition disk next to it. These weights together are also directed at more than 200 kilograms. It is a bit difficult for such a heavy artillery to quickly rotate and pitch by human hands~ www.wuxiaspot.com~ Therefore, in history, with the exception of those used as light artillery on the wheels of land artillery, most of the 1-pounder guns were equipped with gun mounts similar to later generations of artillery, and they were even placed above the barrel. A pillar was added, and the huge cooling water bucket of the 37mm gun was tied with an iron ring under the pillar.
In fact, Bavaria also adopted a similar mount. (For details, please refer to the wiki. You can also look at the pitch and rotation system of the 37 anti-aircraft gun.) But unlike in history, Bavarian engineers considered abandoning the cooling water bucket. First of all, this thing is not very in the Russian opinion. necessary. After all, for the Russians, this type of shell cannot be designed like a machine gun, and the firepower continuity requirement is not high.
Secondly, artillery has too many requirements for cooling water, almost three times that of machine guns! Moreover, the fired shells are after all, the amount of cooling water must be huge, and the vehicle carrying capacity is inherently limited. The Russians and Bavarian engineers have been entangled with the issue of shells and cooling water. (Don't think that a machine gun with 5kg of water is enough, that is going to happen, there is a machine gun in actual combat, a company of people use a kettle to send water...)
In the end, Bavaria’s proposal was to use heavy heat sinks to replace the cooling water, and to further reduce the rate of fire, from 300 rounds per minute to about 180 rounds per minute. In this way, it can be guaranteed that the artillery will not overheat when using the 25-round drum.
The second is more.......
