Zhang Xuewu didn't say anything, not even hint, but only took everyone to visit the design institute and assembly workshop, the director of the armor design institute was the German-Jewish Sivet. Nathan, Hewitt. Nathan is one of the very politically far-sighted nerds, and when he senses that the wind is not going in the right direction in Germany, he resolutely gives up his privileged life in Germany and crosses the ocean with his wife, four daughters and father-in-law's family in the hope of finding an opportunity in Rehe.

Sivet. Nathan is a professor of mechanical engineering at the University of Hamburg, but his main focus is on the new tank. Nathan participated in the development of the Jackal and Leopard tanks, and was driven out of the Tiger program because of his Jewish status. Nathan was able to leave Germany thanks to Goering's instructions, and for such a tank design genius buried by history, Zhang Xuewu could only sigh helplessly.

Zhang Xuewu once had a complaint against Sivet. Nathan mentioned the design of the so-called T34-76 tank, compared with the original design of the T34 series tank, such as reducing the hull height, redesigning the three-person turret, the new fast motor drive rotation mechanism, and the new turret with a lower frontal hit rate. The tank designed by Nathan scared Zhang Xuewu a lot! What kind of new tank is this! This is the prototype of the future Soviet-made T44 main battle tank!

The historical Soviet-made T44 medium tank is the successor model of the T34-85, which belongs to the Nizhny Tajik tank series, and the Soviet Army developed the T44 mainly to resist the German army, because the T34-85 medium tank equipped by the Soviet Army at that time was obviously inferior in the confrontation with the Leopard tank, so the Soviet Army urgently needed a tank that could confront the German Leopard tank.

Zhang Xuewu handed over the design of this new type of tank to the production department, in order to demonstrate that its overall design can be used and coordinated, for a successfully designed tank, while ensuring the firepower output and destroying the surname, the greatest consideration for the survival of the tank is the top priority of a successful tank design.

The M4 Sherman Medium Tank Series and the T34 Medium Tank Series are both famous medium tanks in World War II, and many people only notice the success of the M4 Sherman Medium Tank Series and the T34 Medium Tank Series, but ignore the huge losses of these two vehicles during World War II.

In particular, the T34-76 and T34-85 medium tanks, the two main battle models, suffered huge losses on the Eastern Front, and in the historical Battle of Kursk, although the Soviet army won the final decisive victory, the German side of the 30 elite divisions, including seven armored and tank divisions, were defeated, and the rest suffered heavy losses. It lost more than 180,000 troops, about 900 tanks, 3,000 artillery pieces and mortars, and more than 3,700 aircraft.

The Soviet army's results were undoubtedly very brilliant, but the Soviet army's casualties in the Battle of Kursk remained in the category of secrecy until later generations, and it was not until the disintegration of the Soviet Union that it was officially made public, and the Soviet Army paid a heavy price in the Battle of Kursk, losing more than 800,000 troops, more than 6,000 tanks, more than 5,200 artillery pieces, and more than 1,700 combat aircraft.

Undoubtedly, the Germans invested a large number of new weapons for this offensive, including Tiger and Leopard tanks, as well as Tiger anti-tank destroyers and Ferdinand anti-tank destroyers, as well as Vespa and other self-propelled guns, and the air force invested Focke-Wolf 190A fighters and Hankel 129 attack aircraft.

In the battle of armored forces, the German Tiger tank's 56 times the 88 mm gun of the barrel caliber had a clear advantage, while the 76 mm gun of the Soviet T-34 tank could not pose a threat to the German army at the same distance, so the Soviet tank rushed to the German tank group at full speed at full speed. After intending to get close to the German tanks, the T-34 mobile surname was used to take advantage of the bulky Tiger tank. But in the course of the group's charge, the Soviet tanks paid a huge price, and the Soviet Air Force destroyed far more German tanks than its tank units.

It is obviously impossible to mass-produce tanks in large quantities with Zhang Xuewu's weak industrial base, even if a large number of tanks are produced, fuel is also very tight, so Zhang Xuewu finally decided to study a medium-sized tank that is most suitable for Rehe and the actual situation in China among the T44 and Leopard tanksWith advanced technology to integrate cross-era design ideas, Zhang Xuewu believes that it will still work.

What makes Zhang Xuewu more relieved and satisfied is that now by Sivet. The research and public relations team composed of Nathan and others can always turn the theoretical design proposed by Zhang Xuewu into reality in a timely manner. In the eyes of Nathan and others, Zhang Xuewu is a very magical genius, and his whimsical ideas can become the results of theoretical data?

In order to be able to have its own military industrial system, Zhang Xuewu introduced the latest 12-cylinder water-cooled diesel engine production line from the Soviet Union, the maximum power of Guo Liufu's 12-cylinder water-cooled diesel engine is 580 horsepower, Guo Liufu's 12-cylinder water-cooled diesel engine is the latest research results of the Soviet Union, but because this diesel engine is still in the stage of technical review and demonstration inspection, the Soviet Union has no need for mass production, so it was successfully sold to Rehe at a high price. The Soviet side also wanted to take this opportunity to test the actual combat capability of the 12-cylinder water-cooled diesel engine of Guoliufu, which could save a large part of the expenses for the Soviet side, and only actual combat was the only criterion for testing combat effectiveness.

In terms of overall design, Zhang Xuewu still prefers the low body, the design of the narrow arc turret, the low body helps to improve the battlefield survival and concealment of the tank, compared to the design of the T44, the German Leopard medium tank is larger.

pzkpfwww.xstxt.org4 The Sherman tank was the best-designed medium tank of World War II.

The Leopard tank can be said to be a kind of medium tank with a strong surname produced according to the war situation, because when Germany invaded the Soviet Union, the German armored forces soon encountered the Soviet army's KV series heavy tanks and T-34/76 tanks, both of which were superior to all types of German tanks in terms of firepower and armor protection, so Germany decided to develop a more powerful medium tank according to the battlefield report on the Eastern Front, and it could be quickly put into production.

The Panther medium tank weighs more than 40 tons, and it has a variety of variants, its Panther II front armor is strengthened to 100 mm inclined armor in the front, 60 mm in the side, and 40 mm in the rear, using the same single torsion bar system as the King Tiger tank, the same load wheels as the King Tiger tank, and the tracks are the transport narrow tracks used by the King Tiger tank.

In the later stage of the war, according to the combat practice experience, the lower part of the arc gun shield ricochet may penetrate the top of the hull, so a narrow turret was designed, the front area of the turret was reduced, and a rangefinder and communication device were installed inside.

Although the Panther tank is larger in size, the Panther tank adopts a staggered overlapping load-bearing wheel arrangement, and the double torsion bar reading suspension device improves its ability to drive at high speed in bad terrain, which is quite suitable for the road conditions and the lack of railway transportation in China.

Zhang Xuewu required the new medium-sized tank to use special chromium-manganese alloy steel on the protective steel plate, the scientific name of this steel is nickel-chromium-manganese alloy surface carburizing hardened steel, its main surname can be the surface after special process treatment The hardness is as high as 670-700HB, the decreasing carburizing depth is about 40% to 50%, the use of new alloy armor makes the front armor of the newly designed medium tank reach 100 mm, the armor on both sides of the hull reaches 80 mm, and the tail is 60 mm. After assembling a ceramic shock-absorbing sandwich with additional external armor, the combat weight of the hull remained below thirty-six tons.

In terms of power system, Zhang Xuewu asked that the engine be arranged horizontally, so that the arrangement of the power compartment is more reasonable, and the length of the entire body can be effectively shortened, and the pump valve type fuel-saving means of the T34 tank are adopted, and the modified Guo Liufu twelve-cylinder water-cooled diesel engine is equipped to make its off-road speed not less than 45 kilometers, and the maximum marching speed can reach 55 kilometers per hour.

The whole crew should not exceed four people, and the commander's command and communication system, rangefinder and artillery stabilization device should be installed inside the turret, and it was planned to import its reserve technology from the Soviet side, a 100-mm Lotgalov 48 times the caliber of the tank gun, and equip it with an experimental turret for testing.

The data requested by Zhang Xuewu seems to Zhang Xuewu to be very ordinary, but in Sivet. In the eyes of Nathan and other experts, it is a so-called height that has not been reached by predecessors, for these senior technical engineers, the more difficult they will be, because the design of an excellent weapon is enough to make its designer famous in history. Nathan, an absolute expert, said that even the Tiger tank, which the Germans were secretly researching as a technical reserve, could not compete with it. Nathan's only concern was not the design of the tank, but whether the power of the Soviets' 100-millimeter Lotgalov 48 times the caliber of the barrel could be guaranteed.

Sivet. Unbeknownst to Nathan, a few kilometers away at an institution codenamed Research Institute Nine, numerous scientists were working around the clock on a focused charge armor-piercing warhead using the Monroe effect.

Zhang Xuewu refused to leave the wooden model of the new tank for a long time, and there is less than a week left before the prototype test, if the test is qualified and put into mass production, then in the big counterattack three months later, this batch of thirty Avenger medium tank prototypes will be able to gallop on the battlefield!
