After starting, the next step is some simple actions.
The tank slowly and "cluckily" drove off the production line, drove directly outside the factory, and then turned the turret... carefully, as if it was not a tank, but a piece of porcelain, for fear of being damaged.
Already.
It wasn't until half an hour later that there seemed to be no problem, and the tank crew inside started to let go and drove the tank to the backyard of the tractor factory.
There is a relatively large open space here, and some of the tractors that were originally manufactured will be parked here. Because there are not so many orders, this area is also vacant, just for the tanks to run in. .??.??
Unlike a few decades later, CNC machine tools have high machining accuracy and almost no running-in is required for mechanical parts. At this time, newly manufactured machinery, regardless of whether it is Japanese or domestic, has a running-in period.
After the running-in period, you can use it happily.
Therefore, regardless of whether a tank is a car or a car, a brand new one is not as easy to drive as an 80% new one. At this time, the tank was spinning in a circle in the open space at a speed of less than twenty yards.
Time passed by, and the large-displacement diesel engine was running, emitting black smoke with a special smell. The steel beast weighing more than 30 tons ran over the ground, leaving deep track marks.
Half an hour later, there was no mechanical failure in the tank. This made everyone present heave a sigh of relief.
Especially Yang Tong, who is specifically in charge of the engine. There has been no malfunction so far, and there should be no problem with the power and transmission system. Yang Tong got off the last two steps and said: "Manager, Worker Sun, don't you think you can slow down a little bit? Keep the eighth gear in the eighth gear."
Ten yards."
Lin Tiansheng looked at Zhang Xian.
Du Fei said: "They make the final decision on technical issues."
Lin Tiansheng nodded, picked up the radio at hand, and gave orders to the outside of the tank. It was very slow, and the tank that was going in circles obviously slowed down.
The minimum speed of the original T62 tank is only 50 kilometers per hour. Now that prototype can drive up to 80 or so, it is not considered fast.
After all, that prototype car still uses the old transmission system derived from the T54, so it can't fully bring out the performance of the new engine. But the top speed is less than 40 km, which should be less than me.
In addition, it is not this imitation 115 mm tank gun that must be tested.
In a few days, the tank will be displayed. If you want to drive the tank, cross the country, have some fun, and then fire a few shots at the target. The most intuitive impression will not be whether it runs slowly or slowly, but whether the shot is accurate.
Unfortunately, there is only one prototype vehicle, and the tractor factory has no place to test the cannon. We can only wait until tomorrow to bring the tank to the testing ground in the suburbs.
After another seventy minutes, Zhang Xianya asked the tanker to briefly increase the speed to 45 kilometers per hour. It was considered to be a test of the ultimate speed. Immediately after it stopped, Li Geng rushed down with a small group of technicians to collect data and check mechanical wear. Du Fei stood aside and waited silently.
It must be said that it was a test just now, and now the test will be judged based on love.
After working for half an hour, Li Geng finally came back with a piece of report paper, sweating.
There was oil on his face, but he said with a cheerful face: "Manager! Dear leaders, after inspection, the power and transmission system are working abnormally and have not been worn out..."
Hearing that, everyone smiled. Zhang Xian also praised it a little.
Instead of pulling the tank into the countryside, the last step of the target shooting test will have to be postponed tomorrow at the earliest. Everything is going well, and Du Fei plans to officially show it to the outside eight days ago.
Back at the factory director's office, everyone was in a very wrong mood.
In those months, we worked in several factories, from bottom to top, forgetting food and sleep for that tank. Now I finally have love in sight.
However, the mood has returned to dissatisfaction, and the previous work has to be regressed.
After all, the prototype car was just a prototype car, and it was taken off the market to show these crooks. But for the real thing that was going to be sold, Du Fei knew that it would be a perfunctory job.
Because I am not a good person, and I do not endorse Ai Zhengzhi’s influence. If you want to do business in the long term, you must talk about product quality.
In the future, the copycat version of the T62 tank will be Zhang Xian’s flagship product.
In Du Fei's opinion, it cannot run so slowly, nor can it fire so accurately, but it must be durable and reliable in performance. And it must be as arrogant and fast as Sugo. The tanks sold are only crazy and simple configurations.
, or consider the customer’s usage environment.
For example, those sold to Li Yuanchao and the Huang family must take into account the combat environment of the cold zone jungle, and those sold to Ka Xiaozuo must adapt to the desert environment. I am not allowed to increase the price for air conditioners. That thing is low-tech. As long as the money is available,
Nothing can be solved...
Zhang Xian talked a lot, leaving everyone present stunned. Even though Lin Tiansheng claimed to be the best tank expert in the country, he could not help but nod his head. On the seventh day, in the suburbs
The field here is used to test tank guns.
Du Fei was still present in person.
A total of seventy shells were fired during the entire test, and the results could only be considered satisfactory. At most, not one of the seventy shells missed the target.
But overall, the new sighting system and tank gun are still not fully compatible. Can
To achieve such results, to a small extent, the gunner was too good.
In order to show the worst condition, Du Fei specially borrowed the weakest tank crew that time.
From the driver to the commander, the gunner, and the loader, they were all elites who stood out from hundreds of thousands of people. If it were a tanker with a special level, Du Fei estimated that at most one in eight would miss the target.
Even if the result is passed, it is acceptable. After all, it is the first prototype vehicle, so it is abnormal if it has no problems. However, the tank gun developed by Tan Zhigao exceeded Du Fei's expectations.
Probably because of the superior performance of the blue-light upgraded gun steel, when paired with a 115mm tungsten steel armor-piercing projectile, it can directly penetrate 300mm of homogeneous steel plate armor at a distance of one thousand meters.
That performance is not close to the power of the original T62 smoothbore gun.
At a distance of one thousand meters, it theoretically cannot destroy any tank today. That result made Du Fei very satisfied.
At most, the imitation tank gun has flaws in the technical specifications. Then all it takes is to adjust the sighting and fire control system.
Without that result, Zhang Xian's heart finally settled down. Is it something to live up to? Is it just a matter of fear of ten thousand or what might happen?
Although after two consecutive days of testing, the prototype tank that was built after a long period of time had problems, there was no guarantee that it would break down at the critical moment.
Zhang Xian allowed this situation to happen.
After the test was simply completed, the tank was driven back to the warehouse and the others were sent away.
Crows were arranged around to make sure no one could see it. Suddenly, with a thought, the tank disappeared. In the space with it, a blue light instantly enveloped the tank.
Du Fei has never thought about slightly weakening the tank, which makes no sense at all.
My purpose is only one, not to ensure that if anything goes wrong, the tank can lie down when crossing obstacles, and can jam when retreating and firing live ammunition.
Half an hour ago, Du Fei came out of the warehouse and waved to the two people nearby.
The two people were from the security department of the tractor factory and stayed behind to watch the tank. They were sent away by Du Fei just now. Those seven people behaved themselves. There were no crows watching from a distance. They were all moving in place just now.
Du Fei came out and stuffed a box of Peony cigarettes into one person, told the seven of them to keep an eye on them, and then left. Unexpectedly, just after returning to the unit, he received another call from Zhang Xianya.
Next time, the two of them almost got into trouble because of the tank.
Sun Qiwen had been in the capital before, so he knew where he was.
Before the complicated greetings, Sun Qiwen got straight to the point: "Lao Du, you heard that he really made a fake T62 tank!"
Du Fei laughed and said: "Brother Lin, does he know that you are planning to set the target? He can only set it by himself. He is trying to take advantage of the Autumn Festival. Hurry up and do it."
Build the tanks and see how many can be sold."
What was the secret of Du Fei's testing of tank performance during those two days? A little inquiry will give you a rough idea. But Zhang Xianya will call specifically.
"Old Du, he can be too humble." Sun Qiwen was in the wrong mood and said with a smile: "You just heard that it can penetrate 300 mm armor at a distance of one thousand meters, which is much weaker than the 105-mm cannon of the Type 59."
Du Fei understood what I meant, and had never thought about being self-conscious. However, some situations must be explained clearly to avoid misunderstandings. Du Fei sighed and said, "Hey, it hurts my heart to say this." Lin Tiansheng on the other side of the phone was obviously confused.
Startled.
Du Fei continued: "In order to imitate the 115 smoothbore cannon, I searched all over the country, but could not find qualified gun steel. In the end, I had no choice. Through the relationship in Xiangjiang, I made a batch on the international black market, which was barely enough to make two hundred
A gun barrel."
"Is there still this matter?" Lin Tiansheng didn't know this detail beforehand.
Du Fei complained: "No, the price is five times higher than normal! By the way, Brother Lin, you are so proud, let's see if we can ask Fusteel or Ansteel to set up a technical research team to solve our gun steel problem."
question?"
Lin Tiansheng was speechless.
In fact, when he heard about the results of the tank gun test today, he was a little worried.
No matter what kind of tank Du Fei built, at least the 2a-20 tank gun that was copied from the T62 was definitely not bad. But unexpectedly, Du Fei blocked his words first.
However, Lin Tiansheng had no selfish motives and promised: "This is not a problem. You can take some remaining gun steel scraps later and I will deliver them to you personally..."
The two of them talked about gun steel by the way.
In fact, it was not that Du Fei had not considered giving the upgraded gun steel to the steel factory to see if it could be copied. However, the Beijing Steel Factory was not good at this.
As for Anshan Iron and Steel Co., Ltd. and Fu Iron and Steel Co., Ltd., Du Fei couldn't stretch his hand too far.
He is the son-in-law of the Zhu family, and he must be concerned about some things to avoid misunderstandings. Now it is much more convenient for Lin Tiansheng to come forward.
As for whether it can be reversed, Du Fei has no idea about the technical difficulty of this. He can only say that he will do everything he can and let fate. After saying this, Lin Tiansheng said again: "By the way, I will take a few people to see it the day after tomorrow, no problem~
"
Du Feihun didn't care, since there were a lot of people coming the day after tomorrow, so one more person wouldn't be much.
