What should I do if I see that the designed tank is not appreciated? Koshkin made a choice, came to a big roundabout and personally led two T-34 tanks on a long-distance test of Kharkov-Moscow-Smolensk-Kiev-Kharkov, through which the reliability of the tank was confirmed and Stalin was impressed by the test in Moscow.

It's a pity that the weather in the Soviet Union, the big guys all know, the weather is cold, this Koshkin was originally a technician, his health was not good, in the process of the experiment, he contracted pneumonia, coupled with overwork, and finally died.

He didn't see this tank shine in the war, and the proud T-34, which went through the entire Second World War, then became the T-44, and after improvement, the T-54 became famous all over the world!

Now, when Qin Zhenhua mentioned this matter, it was naturally something to refer to, he looked at Zhu Lao and nodded seriously: "That's right, I'll drive all the way over!" From Prairie City, let's go to the capital! With our practical actions, we will show the excellent performance of our 80 tanks! ”

If the superior doesn't approve of it, then show it to the superior!

From the city of the steppe to the capital, hundreds of kilometers away! There are grasslands, mountains, hills, and all kinds of terrain along the way, and the whole trip is estimated to reach thousands of kilometers! For 80 tanks, it was an excellent demonstration to cover this distance!

There is no such thing in China, the tank leaves the factory, that is through the train, a machine factory directly has a special train station, there are military trains almost every week, the tank leaves the factory, it can always reach the target unit, in the shooting range of the army, back and forth, there has never been a tank factory directly to the troops.

It's a long-distance test!

"But what if you destroy the road along the way?" Wang Erzhu asked on the side.

If the tank wants to go out, then it has to walk, and what way? If you go into the wild, the large meadow will be destroyed, after all, he grew up on the grassland, and he always feels that it is not good to do so.

"We use rubber tracks." Qin Zhenhua said: "Anyway, when participating in the parade, you have to use hanging rubber tracks, so you can't damage the ground of the parade ground." ”

The track is a foreshadowing for the advance of the tank, and it is precisely because of the track that the tank can walk on the ground, but it is also because of this track that the tank has a great destructive effect on the ground in the process of advancing.

Under normal circumstances, tanks operate in the field, so even if they destroy the ground, it doesn't matter, it is considered arable land, but if it is a military parade, it is not good to destroy the ground.

Therefore, in this planned parade, all tanks will be installed with rubber tracks.

(East China Zhixiong is military blind and scolded miserably, I don't know if anyone will say that the single-pin track can't be glued!) Russia has reached the present, during the military parade, there are still a large number of tanks that destroy the ground, just like the T-72 tank, and they do not hang glue, because they are single-pin tracks! Well, East China Zhixiong, who is military blind, doesn't know whether the single-pin tracks can be glued, but East China Zhixiong knows that since the military parade in 1984, all the vehicles participating in the parade are hung with rubber tracks. This is true of both the latest 79 tanks and the old 59-2 tanks. ）

The rubber track can not only solve the problem of destroying the road surface in the city, even if it is in the field, the rubber track can bring a more comfortable riding environment because of the buffer in contact with the ground, so the track with rubber has excellent performance.

The only downside is that it's too expensive!

After all, to make a pair of tracks, the price is not small, and if you want to hang glue on it, the cost is higher, this is not ordinary rubber, it must have higher tensile strength and tensile stress, higher wear resistance, good scorching performance and processing operation safety and so on.

Therefore, refining this kind of rubber is also a special mission, and in China, in the past few years, qualified rubber for track hanging rubber has been manufactured.

Natural rubber, sulfur, zinc oxide, stearic acid, paraffin, pine tar and other raw materials are used in the hot refining and vulcanization process of this kind of hanging glue, as well as corresponding accelerators and antioxidants. However, the performance of the rubber track is just an ordinary test.

After all, this thing is too valuable, and ordinary troops don't need it, even after it is designed, simple tests will be put on the shelf, and it will not be taken out until the military parade.

Just right, also test the performance of this kind of rubber track, how much will the rubber block fall down under various road surfaces? Will it stand the test?

"I think so." Zhu Lao said: "This long-distance test is also of great significance to the development of our equipment. However, for the sake of safety, I would suggest that two more logistical vehicles be added. ”

It's not okay to send only one tank out, not to mention anything else, in the wilderness, what if the gas runs out?

There must be a logistics support vehicle, a transport of oil, a transport of various spare parts, repair tools, what if it breaks?

Don't fight unprepared battles.

Zhu Lao's suggestion made sense, and Qin Zhenhua also nodded solemnly: "Let's prepare for a week, and after a week, we'll set off!" ”

After hearing the news, the whole factory was boiling, and a worker wrote a petition asking to follow the test team together, everyone's enthusiasm was high, and the story about the T-34 test was also circulating in everyone's mouth, and everyone was full of expectations.

And Qin Zhenhua, who was busy because of this incident, also encountered a lot of new problems, such as the next day, Xie Huimin came up.

"Zhenhua, can the self-propelled anti-tank gun we jointly develop participate in this long-distance test?" Xie Huimin asked Qin Zhenhua.

Self-propelled anti-tank gun, there is no official identity yet, it is still self-funded research and development by two factories, it can be said that if this self-propelled anti-tank gun can be in the limelight in this long-distance test, then maybe, the superior has taken a fancy to it, and it has turned into a positive identity?

They can't wait for that.

However, this proposal was immediately rejected by Qin Zhenhua.

"No, this self-propelled anti-tank gun, which has not yet completed all the tests inside the factory, does not meet this condition." Qin Zhenhua said coldly, looking at Xie Huimin's unwilling face, he could only lower his voice and make a patient look.

"Lao Xie, I know what you think, but, when you don't have a bottom in your heart, don't take it out, if something goes wrong on the road, it will be counterproductive, not to mention anything else, on the route we are on, there are large areas of mountainous areas, our self-propelled artillery has a high center of gravity, what if it rolls over? I can't afford that. ”

So, Xie Huimin could only give up.
