According to the intelligent brain scanning and simulation test, the 88mm tank gun, 48 times the diameter, 4.8 meters long, the effective range of 3.5 kilometers, the weight of the bullet is 6.2 kg, the muzzle velocity is 282 meters / second, the maximum rate of fire in the tank is 18 rounds / second, 1500 meters of shooting, and the vertical penetration depth of the homogeneous steel plate is 80mm, which can destroy all tanks before 1940, and the effect can only be said to be barely qualified.

At the same time, the torsion bar suspension chassis has also been tested, which can withstand a maximum of 40 tons of heavy loads, a track width of 640 mm, a length of 3.6 meters, five pairs of load-bearing wheels, and a maximum driving speed of 42 km/h and a trouble-free driving of 420 kilometers in the best state.

In the best state, Liu Yun was also drunk, remembering the German Leopard tank, with a total weight of 45 tons, an engine of 700 horsepower, and a maximum travel speed of 46-55 km / h.

It seems that this chassis still needs to be improved, looking at Zhang Sili with two dark circles under his eyes, and the melancholy von Schnoder, Liu Yun also understands in his heart that these two people really tried their best.

In general, the chassis of the new tank was successfully made, just waiting for the engine, artillery fire, etc., assembled together, it can also sweep all the current multi-turret cults, isn't it 5 years from 1940, think about it another way, that is, it is not as good as the Leopard and T34 of World War II, it is better than the German tank that cannot be made at present, the third and fourth tanks.

Liu Yun didn't say more, put on a pair of white gloves, began to assemble the first tank engine, first used the brain to screen out the unqualified parts, and then in a bunch of parts and engine spindles, to find the best assembly route, and then according to the road map, one by one, the action is not fast or slow, orderly, the Chinese and foreign experts next to it watched with relish, and the whole process was recorded with heart, ready to be used as a flow chart for future assembly.

This time, a total of three sets of engines were assembled, six engine units, each unit had 14 cylinders, a total of 84 cylinders, a single standard engine unit, 600 mm square in size, weighing 38.1 kg, according to the difference in materials, divided into three types: upper, middle and lower, namely Hanyang Steel Mill's self-made steel, special imported steel, and alloy steel collected by ants.

In addition, Liu Yun also used ant robots, secretly processed two units, but this time I didn't take them, these two units are standard 2×400 horsepower, just in case of preparation, if there are no special circumstances, I don't plan to take it out at all, after all, it is still 1934, and this kind of near-perfect engine appeared in Huaxia, it is too appalling, and it is better to be low-key.

It took more than 40 minutes to assemble the first engine unit, and it took nearly three hours to assemble the four units, and the last two were low-grade engines, except for the main shaft, which were basically all domestic materials.

For this revolutionary engine, whether it is the Chinese soil experts or the German foreign experts, they have been salivating for a long time, looking at Chief Engineer Liu dryly, and the four were assembled in an orderly manner, and they were already eager to try, so after an order, like a hungry dog grabbing a bone, they rushed up.

Fortunately, there are two units, exactly two German experts, one for each person, and the rest of the soil experts, automatically divided into two groups, to help to lay down, and they don't care whether they are dirty or not, they all do their best, and with professional instincts, it only took less than 20 minutes to complete the assembly.

The results of the brain scan were more accurate and perfect than someone assembling according to the road map, which made Liu Yun very embarrassed for a while, and then he knew that even if he had advanced technology, in some fields, he was still far inferior to these experts who ate professional meals.

After the assembly of the three sets of engines, it is the engine power test, in this regard German experts have long been prepared, not only a series of test equipment, but also simulation operation in various situations, and finally installed on the newly baked tank chassis test run.

After rigorous and rigid German experts hands-on, it didn't take long for six engine units to test the results, the first gear, the material is ant alloy, assembled by Chief Engineer Liu, the test time is 10 minutes, the maximum torque output is 374.5 horsepower and 375.2 horsepower, the difference between the front and side is 0.35 horsepower, and the linkage torque output is 750.3 horsepower, and the fit is average.

The second gear, the material is special imported steel, but also Mr. Liu's hands, the test time is 10 minutes, the maximum torque output is 359.6 horsepower and 360.2 horsepower, the positive and secondary difference is 0.3 horsepower, and the linkage torque output is 720.2 horsepower, and the fit is average.

The third gear, the material is Huaxia domestic steel, jointly assembled by experts, the test time is 10 minutes, the maximum torque output is 340.0 horsepower and 340.1 horsepower, the positive and secondary difference is 0.05 horsepower, and the linkage torque output is 680.0 horsepower, with excellent fit.

This result was much unexpected by Liu Yun, even he, a liberal arts student, also knew that his own craftsmanship was a bit trendy, and the accuracy of the assembly was not an order of magnitude at all with the level of experts, but this result surprised the most rigorous German experts.

German experts believe that with such a backward agricultural country as China, it is already a miracle to be able to make such an engine, which is already the greatest gift from God, if you get to Hamburg, Germany, it can definitely reach 800 horsepower, so for Liu Yun, the chief engineer, and the soil experts in Huaxia, I would like to pay high respect, thinking that they are the greatest mechanical experts, and this engine is the most brilliant jewel in the crown of the mechanical empire.

This result made Minister Kong and Major General Qin very excited, not only did they raise their chests one foot higher, like two big roosters, but also repeatedly told the experts of Huaxia that the Nanjing Nationalist Government would never forget everyone's merits, and when the German General Adviser, General Seckert, finished inspecting the Hanyang Arsenal, they would immediately calculate the credits, and everyone would count one for one.

Even if he can't be promoted to the third level, the personal bonus is real, as little as tens of thousands of silver dollars, and as much as no cap, even if he is a calm soil expert, he is also enthusiastic and dizzy, more effective than Liu Yun's primary treatment, and in an instant, almost all the dark circles under his eyes disappeared.

Finally, Liu Yun didn't bother to pay attention to the test run on the tank chassis, but took advantage of the time for everyone to continue the test run, and wrote a work plan, mainly to install thick armor on the tank, which of course could not use ant alloy, and even imported special steel could not be used, only the steel plate of Hanyang Iron and Steel Plant was used.

After the test and simulation of the brain, the modular decomposition, the entire armor will be composed of hundreds of standard modules, under the forging press of the steel mill, it can be quickly stamped successfully, in the critical eyes of the Germans, of course, it is still a little rough, but in the case of war, it is the best choice.

What's more, Liu Yun also borrowed from the Soviet T34 tank, and tried his best to form a 30° angle between the most vulnerable parts, which increased the thickness of the defense in disguise.

After the wisdom of the brain perfected, the thickness of the armor of this new tank, not counting the angle of inclination, is 100mm homogeneous steel plate on the front, 70mm on the side and back, and the total weight is 38 tons.

Liu Yun understands that this tank is good enough, and if it is perfected by the Germans, it will probably not be weaker than the 1941 Leopard tank.

Liu Yun's ideal plan is to miniaturize the communication system on the Hawker fighter and use it as the communication equipment on the future tank, and as for the aiming system, condensation system, and security system, all of which are arranged for the experts of "one house and two groups".

The experts have not finished testing all the engine units, it is getting late, under the forced dismissal of Liu Yun, everyone has to disperse, these new engines, tank guns and tank chassis will be guarded by the arsenal guards 24 hours a day, and even after a group of experts leave, other idle people, etc., are not even allowed to look at it.

Three days later, when the sky was dark, Liu Yun was still sleeping in Kong's villa, and he was woken up by the guards of Qin Guodong, dressed in a daze, and walked out of the gate yawning.

There was already an arsenal passenger ship waiting by the riverside, and when they hurried to the Hanyang Arsenal, Minister Kong, Qin Guodong, experts from joint research and development, and a group of relevant administrative personnel were already waiting on the riverside, ready to welcome the arrival of Admiral Hans von Seckt.

If it weren't for Qin Guodong's admonition and Minister Kong's sharp eyes, Liu Yun would not have wanted to wait, and at this moment, from the surface of the Yangtze River, three warships slowly drove up, and everyone suddenly lifted their spirits, knowing that the German general counsel had finally arrived.

At this time, Liu Yun inadvertently discovered that Yuan Qi'er, who was in a stealth state, was suddenly frightened, this guy should not want to attack Admiral Seckert, this is the father of the German army, once assassinated, it is not a joke, it is simply a catastrophe.

Liu Yun hurriedly contacted Yuan Qi'er through the ant belt and sternly warned her not to mess around no matter what, otherwise it would not be ruled out that she would die with her.

Yuan Qi'er didn't expect that Liu Yun would react so much, so she had to blink innocently and said in a low voice, "Don't worry, I'm just curious, assassinating a German general, how can it be so easy, there are three masters around, no matter which one of them, it's no worse than the bronze man, where can I afford to provoke it, okay, I'll leave, okay."

After Liu Yun saw a certain master leave, he gradually became relieved, and at the same time, he became curious about the three masters that Yuan Qi'er said, and asked Zhi Brain to scan around, but there was no result.

Just when he was a little discouraged, Zhi Brain told him that the real reason why he didn't scan it was that the masters had not yet exuded the corresponding level of spiritual power, and once they were released, it would be caught at the first time, and once these masters appeared, they would be highlighted at the first time.

Liu Yun felt better, and thought that these masters were more powerful than the bronze man, and they could circumvent the scanning of the Zhi Brain, it turned out that the characteristics of these masters had not been caught by the Zhi Brain, well, after all, it was the Zhi Brain, not the people, otherwise the masters would have been distinguished long ago, and the difference between them and ordinary people.

Soon the warship docked, a thin and tall German general, surrounded by a large group of people to get off the warship, this person is older, about sixty or seventy years old, although he is white, but his face is a little abnormal, even slightly gray, it seems that there is indeed a disease in the body, but also very serious, Liu Yun guessed that this person is Admiral Seckert.

Sure enough, as someone expected, Minister Kong had already stepped up to greet the German general, and when he greeted the German general in German, he was called "General Seckert", and then greeted General Huaxia next to Seckert, who was Admiral He Yingqin.
