Qin Zhenhua and Xie Huimin looked at each other's back as they left, and knew that the other party had no other choice. For the benefit of their own company, they could only choose to cooperate with their own party. After all, the Western world is definitely not a monolithic, and each company is also for itself first.
The company's interests serve.
"Zhenhua, thank you this time." Xie Huimin said to Qin Zhenhua: "If we hadn't had you this time, we would probably have been led by the other party again. These foreigners are so hateful."
Qin Zhenhua smiled and said, "We are now all under the Northern Company. We will develop together and earn foreigners' money together. These are what I deserve. Let's go. Since we are here, let's take a look at the cannons produced by your company."
The Second Machine Factory mainly builds artillery, so when Qin Zhenhua comes here, of course he also needs to see the progress of making artillery.
"They have no air conditioners in the West. Even if they are not very hot in the summer of Europe, staying in the tank is enough." As she walked, Xie Huimin continued to say that she was confused. What should the Westerners do?
of?
"Yes, the temperature inside their summer tanks is actually not low, but it's only a short period of time anyway, so you'll endure it." Qin Zhenhua said: "And they can also use their own vests to
Dissipate heat.”
Vest? Xie Huimin was curious after hearing this.
"Yes, they made their vests hollow and added ice to cool themselves." Qin Zhenhua said, and as soon as they said this, Xie Huimin couldn't help laughing.
This is too primitive.
In fact, the West can do whatever it takes.
Back then, during World War II, Western tanks went to North Africa and found that they were extremely hot. What should I do? I was used to driving the Crusaders and Matilda's British army, and later changed into the US M3 Stuart tank,
It is refreshing because this tank uses an aircraft engine, and its sixteen-leaf engine cooling fan creates a "passing wind" during the tank's progress, effectively reducing the body-sensing temperature of members in the car.
Later, there was a kind of tank that did this, creating convection inside the vehicle body, and even directly building a pipe and blowing the air in front of the tank.
However, this is not entirely beneficial. After entering Africa, the tank hand was surprised to find that the air blowing towards him was not cold at all, but was hot and extremely hot, so it was better not to blow it.
It feels the same as the air conditioning and outdoor unit in the summer.
Therefore, this method was eliminated. Later, in order not to use air conditioners, Westerners thought of another way, using air as a refrigeration work fluid, compressing the air and doing work on the outside, so that the temperature of the air will be reduced, thus reducing the temperature.
The air behind is directly supplied to the passenger compartment, which is very comfortable.
Don’t you dislike the hot air conditioner when you blow the air conditioner? Let’s just blow the cold air like this.
However, it is not easy to compress the air and then let the air do work to the outside world. It can only be achieved at a speed of 60,000 to 70,000 revolutions. Therefore, except for the Russian T-80U that realizes this function, everything else fails.
It's right.
Therefore, we can only use a liquid-cooled vest. Don’t be afraid of it when it is hot. We have ice, which is so primitive and direct.
The two of them said and walked into the workshop.
On the production line, Rong Qiang skillfully operated the deep hole drill, opening a long cannon steel and tiny metal chips kept flying out of the spiral gap of the drill rod, as if in the air.
The dance is average.
"Rong Qiang, what's doing?" Qin Zhenhua looked at the long cannon steel on the production line and sighed: "This cannon barrel is probably the longest we have made, right?"
"Yes, Assistant Qin, do you still remember me?" Rong Qiang asked Qin Zhenhua strangely. He only remembered that the two of them had met once.
At that time, Rong Qiang was an apprentice who had just entered the factory for a year and had tinkered with the thermal sheath of the aluminum alloy outside the barrel. Later, did Qin Zhenhua remember him?
"As long as someone with skills, he can remember it." Xie Huimin said: "However, Rong Qiang is now our technical backbone, and his technology can only be used in our second machine factory, so
What tricks do you want to use to get Rong Qiang away? That won’t work.”
Xie Huimin has always been guarding against Qin Zhenhua. In this era, people with skills can eat anywhere. If Rong Qiang left the Second Machine Factory and went to a private enterprise, it would be a big loss for the Second Machine Factory, even if it was
It's not even possible to go to the first machine factory.
"Old Xie, you underestimate people too much." Qin Zhenhua said in protest to Xie Huimin, then looked at the cannon barrel and said, "What kind of cannon is this made?"
"The 155mm gun with extended barrels." Xie Huimin said: "When we went to Wushui Kingdom to bid, we relied on firepower advantages. Later, didn't the Westerners say that their new generation of artillery has reached 52 times.
We can't fall behind if we have the caliber, so let's do experiments now and make this kind of artillery with a lengthened tube."
Now our 155mm cannon is 45 times the caliber, and all kinds of shooting experiments have been completed. It is a mature weapon system. However, if you want to gain an advantage in competition with the West, you must continue to play.
What you are good at.
Extending the barrel is what we are best at. Now, we see that we will have disadvantages in the future, so of course we need to continue to lengthen it.
First of all, this requires technical support. After all, from 45 times the caliber to 52 times the caliber, the barrel was extended by one meter. After the barrel was extended, it also brought other inconveniences. First, it was processing.
The length of the entire barrel has reached eight meters. It is quite difficult to process such a long barrel and ensure accuracy. Only the most experienced master can do it.
And Rong Qiang, in recent years, has become the most proficient master in this field in the Second Machinery Factory.
Qin Zhenhua nodded: "Yes, it is the most correct thing for us to prepare for the future. Moreover, after extending the barrel, it is not only exported, but the army may also be interested. After all, compared with the 152mm cannon, the performance of this cannon is estimated to be
It can double the increase."
The Army is a nostalgic military, holding the original 152mm cannon, while the 155mm cannon from the Second Machine Factory can only satisfy the army if it is crushed with absolute performance.
"This gun requires very high accuracy. Rong Qiang is studying it. I hope his hand can successfully build our gun. However, you just said that this is the longest barrel, not
