Chapter 287 The birth of the iron horse

The new fighter Falcon can be said to be responsible for different tactical tasks such as competition for air supremacy, ground attack, long-range escort, etc. It is the core secret of the tenth war zone. It is placed in the new tank developed, but Zhang Xuewu is too urgent. The production and assembly of the prototype vehicle has entered the debugging and testing stage. After all the designs are basically Zhang Xuewu directly specified that the birth and mass production of each new weapon have to go through a large number of data tests, and actual combat tests. However, the car is low, with four members, a circular arc turret, staggered overlapping load-bearing wheel arrangement, and the double torsion rod reading suspension device improves its high-speed driving ability in bad terrain. Force, equipped with a 100mm Lotgarov 48-fold tube caliber tank gun, special chromic manganese alloy steel front alloy armor thickness 120 mm, positive oblique 240 mm, the test effect of the medium-sized tank with a weight of 3.2 tons is very good.

1.7 meters of concrete obstacles, 1.7 meters wide anti-tank trenches, the whole vehicle is immersed in water, the effective range penetration of the artillery, the new type of armor-piercing bullets, etc. have all been tested. The data of the test shows that the modified car can be directly carried out mass production, although the special chromium-manganate alloy steel production in Baotou Industrial Zone The quantity is not large, but it is still certain to produce 25 vehicles a month, but Zhang Xuewu has never issued a production order?

Just named the new tank "Iron Riding Medium Main Battle Tank", produced 120 as a reserve, and transferred the personnel of the 1st and 2nd Armored Divisions for closed secret evaluation. It was not to be a new equipment. Zhang Xuewu's decision made the officers and soldiers of the 1st and 2nd Armored Divisions of the Youth Army lose a lot. Hope.

Because in Zhang Xuewu's view, the mass production of "iron riders" is simply a radical waste. The opponent of the iron riders is not me, but the iron armored army that positions the future Soviet and Russian red empire. It is enough to deal with my thin-skinned cans with a "bladder", which is already very face for me, and Zhang Xuewu is also I'm worried that if the data of the iron cavalry is exposed, the tenth theater under his command is now carrying out a series of close cooperation with the Soviet side. If the Soviet side requests a sample of the iron cavalry, he can't refuse. Once the Soviet army is equipped with a large number of iron cavalry medium tanks, then I'm afraid that 1941 will not be Hitler's million army. It was crushed over, but the Red Legion was killed like a landslide.

Therefore, all the data of the iron-rid medium-sized tank was secretly blocked by Zhang Xuewu. He claimed that a breakthrough had been made in the development, and the surname could completely surpass the German leopard chariot. The Soviets could be clear about the foundation of Rehe through cooperation. They knew that this was probably the failure of the development of Rehe. The necessary publicity to put powder on the face, coupled with the delay in equipping the new tank with two armored divisions, the Soviets only regarded it as a joke.

The Panther tank sold by the Germans to Rehe has been studied in detail by the Soviets. They are working hard to develop their own next generation of main battle tanks to deal with the potential threat of the Leopard. Although on the surface, the Soviet Union fully supports Rehe to resist the Japanese army, in private, whether they are Soviet instructors and experts, they are also They look down on the backward China. For the yellow people, they seem to have a natural sense of pride and abnormal superiority.

Zhang Xuewu is actually a very unkind person, because the troops in the tenth war zone introduced a Soviet tank gun with a 100mm Lotgarov's 48-fold barrel diameter smooth-bore gun, and in fact, the 100mm Lotgarov's 48-bar tank gun with a barrel caliber. The data on armor-piercing thickness, accuracy and other aspects are not ideal, because tank guns are mainly divided into cannons and smooth-mooth guns. Tank guns are the main weapons of tanks.

Tanks are mainly engaged in close-range combat. Tank guns are required to have high effective fire effectiveness and penetration at a distance of 1,500 meters. They use reliable tank armored vehicles to annihilate and suppress the enemy, destroy the enemy's living forces and destroy the enemy's firearms and fortifications. Tank guns evolved from small-caliber cannons. It can be said that most of the tank guns during World War II were cannons with high initial speed and long-body cannons.

Zhang Xuewu's application of new technology has always been at the forefront of the world. For the first time, the iron-riding medium-sized tank adopts a high-low and horizontal two-way stabilizer to achieve a high-precision knotting method. This extremely popular technology in later generations has become the key to ensuring the shooting hit rate of the iron-riding medium-sized tank. .

You should know that the tank is a main battle weapon combined with attack and defense. The tank gun smoothbore gun with a 108 times the barrel caliber of Lotgarov is exposed to the sun and the upper and lower temperature difference of the body tube is about four, and the muzzle will be offset by two dense positions accordingly. Under normal circumstances, if the shooting accuracy deviates from two dense When shooting at the square target 700 meters away, it is basically equivalent to firing an empty gun.

For this reason, the barrel of the main battle tank gun of later generations is generally equipped with a heat insulation sleeve. The general heat insulation sleeve is basically made of two layers of glass fiber reinforced plastic, and the middle is filled with foam plastic. There are also a heat insulation sleeve made of a single-layer concentric sleeve made of insulation material or heat conductive metal aluminum, with the air between the body tube and the concentric sleeve as the partition. The hot layer, or arranged with metal and insulating materials, is arranged outside the body tube. Among them, the effect of the latter is very good. The heat insulation sleeve can evenly distribute the heat generated by the cannon firing around the body tube, reducing the deformation of the body tube, thus improving the hit rate of the cannon.

The first method is subject to materials, so there is no surname. The cost of the second method is a great problem. Fortunately, the iron horse medium tank does not need large-scale mass production. Its focus is to win with quality. After all, it is almost the advanced equipment of an era, especially the new armor used by the iron horse with plug-in. Armor greatly improves the battlefield survival coefficient of tanks.

But this is just a shield. The tank needs not only a shield, but also a spear to penetrate the opponent's armor outside the opponent's effective range. The introduction of the 100mm Lotgarov tank gun with 48 times the body diameter smoothbore gun obviously does not meet Zhang Xuewu's requirements. Zhang Xuewu's requirements are An ordinary armor-piercing shell was used at a distance of 1,000 meters to penetrate the Stalin II heavy tank with 120 mm of front homogeneous armor, and the 150 mm of homogeneous armor was penetrated at a distance of 1,500 meters with the latest backup tail armor-piercing bullet.

Because whether it is an armor-piercing shell that can be fired by a German 88 mm tank gun, the vertical armor-piercing thickness at a distance of 1,000 meters is 140 mm, and the armor-piercing thickness of inclined armor is 103 mm. The main weapon of the Stalin II heavy tank is 123 times the diameter. The millimeter tank gun can fire twe-piercing shells and lethal blasting grenades. The armor thickness of 1,000 meters of vertical homogeneous armor is 190 mm. If it is within 300 meters, it will have fatal attacks on both sides and tail of the body of the iron chariot, but fortunately, the 122 mm tank made by the Soviet Union. The cannon is just transplanted from a wild cannon, not a cannon or smooth bore gun for tanks, and its shooting accuracy is very average.

Therefore, Zhang Xuewu needs to equip the iron horse tank with a sharp spear to ensure that it can break through the opponent's armor outside the opponent's range. Zhang Xuewu is still full of confidence in the tungsten-containing tail wing armor-piercing shells designed and produced by Baotou Base!

So Zhang Xuewu gave an order to the artillery research institute to develop a new large-power tank gun with a caliber of 105 mm to 120 mm on the basis of a tank gun with a tank gun with a diameter of 108 times the diameter of 100mm Lotgarov.

This new gun barrel is connected to the tail of the gun with the help of a threaded coupler, which must be easily disassembled. The latch is used to lock the gun, fire the shell, and pull out the cartridge. The latching and closing can be carried out automatically. The rocker uses its two ear shafts to install the gun on the gun bracket.

The tail of the gun should be equipped with a recoil device composed of a re-backing machine and a re-entering machine, which is used to consume the recoil kinetic energy of the gun, so that the recoil part can return to its original position, and put the gun in the front position at any elevation angle to ensure the normal operation of the gun. The launcher is used to launch the launcher. It is required to be equipped with a danger plate to protect the safety of the occupants when firing. The balancing machine on the right side of the gun is used to balance the weight of the shaking part of the gun, so that the gun is light and tilt up and balanced.

Zhang Xuewu's requirements also give the Jewish experts and Chinese technicians of the research institute a headache. The quality of the 100mm Lotgarov 48 times the diameter of the tank gun smoothbore gun is almost extreme. On the basis of its research, it is difficult to make a breakthrough. The barrel length of the tank gun is of ordinary caliber. More than 50 times, because there is only a long-barred gun with a caliber of more than 40 times, the projectile fired has a large muzzle velocity, large kinetic energy, small firing angle, and no more than 45. The trajectory is low, that is, the trajectory of the projectile when flying in the air is relatively straight, which is easy to aim directly. The shooting accuracy is high, and it can penetrate armor at a long distance, which is suitable for flat shooting tanks. Active targets such as armored vehicles and a single vertical target that protrudes the ground.

So the attack team can only choose between the cannon and the smoothbore gun. Finally, the attack team chose the smoothbore gun. Zhang Xuewu is not surprised at all, because the smoothbore gun is the mainstream development trend of later tank guns. It uses a high barrel caliber multiples, so it has a strong armor piercing ability, and its pipe wall is relatively Thick and without uffing, there is no uffing ablation problem, small resistance in the uffing, and a long service life.

In particular, the ammunition launcher of the smoothiole gun is sufficient, and the pressure in the bore is large, so the initial speed of the launch is very large, which can improve the armor-piercing ability of the latest tail wing armor-piercing bullets.

The iron-riding medium tank also adopts the latest technology in the steering mechanism. This kind of secondary planetary steering machine can improve the maneuverability of the tank, so that the tank can use the minimum angle without deceleration in the state of high-speed driving.

In Zhang Xuewu's view, the only thing needed for the iron-riding medium tank is this sharp spear. Before it is amazing, the confidentiality needs to be strengthened.
