Qin Zhenhua and Xie Huimin looked at the back of each other's departure, knowing that the other party had no other choice, for the interests of their own company, they could only choose to cooperate with themselves in the end, after all, the Western world is definitely not monolithic, and each company also serves the interests of its own company first.

"Zhenhua, thanks to you this time." Xie Huimin said to Qin Zhenhua: "If we don't have you this time, it is estimated that we will have to be led by the other party's nose again, these foreigners are really hateful." ”

Qin Zhenhua smiled: "We are all under the umbrella of the Northern Company now, coordinated development, and make foreigners' money together, these are all what I should, go, since we are here, let's take a look at the cannons produced by your company." ”

The Second Machine Factory is mainly for making artillery, so Qin Zhenhua came over, of course, to see the progress of artillery.

"Their Western tanks and armored vehicles are not equipped with air conditioning, even if they are not very hot in Europe in summer, it is enough to stay in the tank." While walking, Xie Huimin continued to say that he wondered, what do Westerners do?

"Yes, the temperature in their summer tank is actually not low, but anyway, it's just a short period of time, and it's over after a while." Qin Zhenhua said: "Moreover, they can also use their own vests to dissipate heat. ”

Waistcoat? Xie Huimin, who listened, was curious.

"Yes, they made their vests hollow and added ice cubes to them to cool themselves." Qin Zhenhua said, as soon as these words came out, Xie Huimin couldn't help laughing.

That's too primitive, isn't it?

In fact, the West is making do with what it can in this regard.

Back then, during World War II, Western tanks went to North Africa and found it extremely hot, what should I do? The British army, who were accustomed to driving the Crusaders and Matilda, was later replaced with the American M3 Stuart tank, which was extremely refreshing, because this tank used an aircraft engine, and its sixteen-blade engine cooling fan created a "piercing wind" during the tank's march, effectively reducing the body temperature of the members in the car.

Later, there was a tank that did just that, creating convection in the body, and even making a pipe to blow the wind on the tanker.

However, this is not entirely beneficial, and when entering Africa, the tankers are surprised to find that the air blowing on them is not cold at all, but hot, and it is extremely hot, and it is better not to blow it.

It's the same feeling as blowing the air conditioner outside the big summer.

Therefore, this method was eliminated, and later, in order not to use air conditioning, Westerners thought of a way to use air as a refrigeration working fluid, compress the air and do external work, so that the temperature of the air is reduced, so that the air after the temperature is reduced is directly supplied to the crew compartment, which is very comfortable.

Don't you dislike blowing the air conditioner directly? Let's just blow the cold air like that.

However, it is not easy to compress the air and then let the air do the work externally, and it can only be achieved at a speed of sixty or seventy thousand revolutions, so except for Lao Maozi's T-80U to achieve this function, the others have failed.

Therefore, there is only a liquid-cooled vest, don't be afraid when it's hot, we have ice cubes, that's how direct it is.

The two said and walked into the workshop.

On the production line, in full swing, Rong Qiang skillfully operated the deep hole drill, opening a hole for a long cannon steel, and the fine metal chips constantly flew out of the spiral gap of the drill pipe, as if dancing in the air.

"Rong Qiang, did a good job." Qin Zhenhua looked at the long cannon steel on the production line, and said with a sigh: "This cannon barrel, I'm afraid it's the longest we made, right?" ”

"Yes, Assistant Qin, do you remember me?" Rong Qiang asked Qin Zhenhua strangely, he only remembered that the two had met once.

At that time, Rong Qiang was still an apprentice who had just entered the factory for a year, and he made out the aluminum alloy thermal sheath on the outside of the barrel, and later, did Qin Zhenhua remember him?

"As long as he is a skilled person, he can remember it." Xie Huimin said: "However, Rong Qiang is now our technical backbone, and his technology can only be played in our Second Machine Factory, so if you want to play any tricks to get Rong Qiang away, it won't work." ”

Xie Huimin has always been guarding against Qin Zhenhua, in this era, people with technology have food everywhere, if Rong Qiang leaves the second machine factory and goes to a private enterprise, it will be a big loss for the second machine factory, even if it is to go to the first machine factory.

"Lao Xie, you underestimate people too much." Qin Zhenhua said in protest to Xie Huimin, and then looked at the barrel of the cannon and said, "What kind of cannon is this?" ”

"A 155-mm gun with a lengthened barrel." Xie Huimin said: "When we went to the waterless country to bid, we relied on the advantage of firepower, and later, didn't the Westerners say that their new generation of artillery has reached 52 times the caliber, and we can't lag behind, so let's conduct experiments now and make this kind of artillery with an extended barrel." ”

At present, our own 155 mm gun, which is 45 times the caliber, has completed various shooting experiments, and it can be regarded as a mature weapon system, but if you want to gain an advantage in the competition with the West, you must continue to play what you are good at.

Lengthening the barrel is what you do best, and now, seeing that there will be a disadvantage in the future, of course you have to continue to lengthen it.

First of all, this requires technological support, after all, from 45 times the caliber to 52 times the caliber, the barrel has been lengthened by one meter, after the barrel is lengthened, it also brings other aspects of inconvenience, first of all, the processing, the length of the entire barrel, has reached eight meters, to process such a long barrel, but also to ensure accuracy, it is quite not easy, only the most experienced master can do it.

And Rong Qiang, in the past few years, has become the most proficient master in this aspect of the second machine factory.

Qin Zhenhua nodded: "That's right, it's the most correct thing for us to take precautions, and after lengthening the barrel, not only will it be exported, maybe the army will also be interested, after all, compared to the 152mm gun, the performance of this cannon is estimated to be doubled." ”

The army is a nostalgic branch of the army, holding on to the original 152-mm guns, while the 155-mm guns of the Second Machine Factory can only be satisfied with the army if they are crushed with absolute performance.

"This cannon requires high precision, Rong Qiang is studying it, I hope his hands can successfully build our cannon, but you just said that this is the longest barrel, but it's not, we have a longer barrel over there."
