The more Xie Kai talked, the more excited he became.

The 59 tanks have the most magic modifications in the world.

Xie Jianguo listened very carefully at first, and from time to time he picked up a pen and wrote down in the work notebook he carried with him, which made Xie Kai even more excited.

This made Xie Kai, who had never received approval from his father, unhappy.

Once he started talking, he couldn't hold it back. Xie Jianguo was stunned when he heard it.

"...Based on the 59 tank chassis, self-propelled artillery can be developed and changed into double 37 anti-aircraft guns and double 57 anti-aircraft guns..."

"Ahem, Xie Kai, what about the fire control system..." Seeing his son spitting, Xie Jianguo had to interrupt his thoughts.

"Um... Dad, we are talking about the fire control system."

"The various modifications you mentioned based on the 59 tank technology have nothing to do with fire control, right?" Xie Jianguo wondered whether his son was smart or stupid.

Xie Kai shook his head, "Dad, this is of great concern. In addition to the 627 Factory and the 541 Tank Base in Zhongtiao Mountain, we also have a full set of 59 tank production technology and production capabilities! Have you forgotten?"

The role of this base is not only for research, but also has an important function of combat readiness!

After the relationship between China and the Soviet Union turned sour, the country began to build the third-line project, the 404 base. It was initially a backup for the 404 nuclear power plant in Yumen in the north. After all, the Soviets helped build it and understood the situation.

The relationship between the two families is bad, and the big brother of the Soviet Union still wants to bully others. In this great northwest, it is too far to transport equipment from other places. What's more, the entire north is their attack area.

Later, when the leaders put it all together, they concluded that after all, a sheep is driven, and a group of sheep is also driven. The Qilian Mountains are so big and still in the desert. It will not be easy to find the Soviets after they invade, so they might as well make it bigger.

If the Soviet Union really invades, heavy weapons and equipment can be produced in the northwest...

If it were not for the production of tanks during the war, the scale of Hongqi Machinery Factory would not be so large.

Xie Jianguo was dumbfounded by his son's unbridled ideas.

"I said you are not sleepy? Can't we discuss it tomorrow? I don't even know what time it is. The wake-up call will be blown in a while..." Liu Xu had gone to bed early, and when he got up to drink water, he saw his father and son.

Still discussing.

"You go to bed first." Xie Jianguo said to Liu Xu, and then asked Xie Kai, "Let's talk about using tank chassis to build excavators first. Our base has more than two hundred chassis in reserve. Don't say it just to show off.

go out."

His son said that the fire control system was too far gone, so Xie Jianguo thought it was better to settle the matter at hand first.

"What's there to show off? Most people know that it's hidden in the cave under the Elaeagnus grove to the west of the base..." Xie Kai curled his lips and said.

After all, tank chassis are not weapons and equipment, and most people don't know what they are used for.

No one can move it, and no one is afraid of it being stolen.

There are no guards.

When the relationship between China and the Soviet Union was at its most tense, a batch of chassis would be shipped over every now and then and stored in the underground factory. After some finishing, they could be assembled. There were also reserves in the tank gun base.

As long as China and the Soviet Union go to war, the base will soon be able to assemble hundreds of tanks to support the front line.

Xie Kai and the others often went there to play when they were young.

Xie Jianguo was even more surprised. He thought it was kept secret.

"Actually, I just knew that the base had that thing, so I said we could build an excavator. The excavator is not as complicated as a tank, does not need armor, and does not need a tank gun. The tank engine is under the rotating part, and the upper turret is removed, and the armor

You don’t need all of them, just add the cockpit and the rotating shovel arm of the excavator to the original turret and it will be OK..."

There is a mature plan for converting the 59 tank into an excavator, and Xie Kai does not need to consider it at all.

Of course, he definitely couldn't say that to his father.

This all became his idea.

"But the tank chassis is for military use and is different from the imported excavators on the market." Xie Jianguo's mind kept thinking about removing the turret of the 59 tank and then adding a cockpit and working cantilever.

What do you think, why do you feel weird.

What's more, the tank chassis is a military material, and it is not certain whether the military will agree to it. This may involve confidentiality.

Unlike other excavator chassis, this may not be accepted by others.

"Dad, you can't think like this. The chassis is for military use, and the production of tanks is for military use; if it is used to produce civilian products, is it still for military use? For ordinary people, military industry is a guarantee of quality! Why are domestic people willing to use prices?

A higher-end imported excavator instead of a domestic one? The quality is not good! The efficiency is not good!" Xie Kai couldn't laugh or cry at his father's idea.

This is the tragedy of being out of touch with the market and not understanding the market.

In the entire base, there is probably not a single person who knows anything about the outside market.

Unlike other state-owned units or military-to-civilian units, you can send people to inspect everywhere.

404 is too closed.

Xie Kai knew that no one in the entire base was willing to accept being separated from the ranks of national defense science and technology workers.

This is Dongfeng City!

Dongfeng City has created countless miracles.

"What's more, once it's built, we don't need to sell it to civilian users at all. Doesn't our military have an engineering force? Isn't the engineering force divided into infrastructure, water and electricity, etc.? They are engaged in construction, and there is a huge demand for such products!

"Xie Kai was planning to do this from the very beginning because he was preparing to place orders for the engineering corps.

"Yes, they are the richest troops in our army." Xie Jianguo nodded.

Although these engineering teams are said to be under military management, they can also be said to be enterprises.

Economically conduct independent accounting and be responsible for profits and losses.

Since the beginning of reform and opening up, the country has been engaged in infrastructure construction, and these troops can be said to be the richest troops in the army.

"Which soldier doesn't want to carry a gun or drive a tank? Although ours is just an excavator, the chassis, road wheels, and engine are all the same as the 59... won't the engineering soldiers like it?" Xie Kai smiled proudly.

If you have money and demand, you are naturally not afraid that the engineering troops will not buy it.

Xie Jianguo kept nodding, praising his son's unique vision, which can be regarded as a military product.

He still likes to buy military products, even if they are not for war.

In this way, the resistance of other comrades will also be reduced. You can't discriminate against the engineering corps as not an army, right?

"Actually, when building an excavator, we need to do the least work, the technical difficulty is smaller, and we can achieve results quickly. The most difficult thing is the hydraulic system. When I was in the Shanghai Stock Exchange, I observed the front bucket.

Convert the power of the engine into hydraulic pressure, which acts on the tooth root at the edge of the bucket... Dad, please bring out some drawings. It's hard to explain without pictures..." Xie Kai continued to analyze for his father.

Let Dad figure it out, and then he can arrange it for others to do.

As a chief engineer, he is mainly responsible for overall control, technical guidance, etc. He does everything himself, so he has to be busy to death?

Xie Jianguo took out some pieces of A3 drawing paper, cleared the coffee table, placed it on it, and handed a 2B pencil to Xie Kai.

Xie Kai grabbed the pencil and directly drew a sketch of the excavator's upper arm, lower arm, and hydraulic support rod, and then drew a bucket. That was it.

It's good if you can understand it.

"This is the structure of the working part of the excavator. You see, this is the big arm part. When the hydraulic support rod is retracted, the big arm hangs down, and when it is extended, it stands up. The largest stress-bearing part of the entire working part is this..."

"This is the forearm part. When you retract it, you pull the forearm outward...and then extend it. The forearm is driven inward by the hydraulic support..."

"The bucket is driven by the hydraulic support on the forearm, and the digging force is also determined by the hydraulic force."

Xie Kai pointed at various parts on the sketch and kept explaining it to his father.

Xie Jianguo had never seen an excavator. Xie Kai pointed to the picture and showed it to him, and he understood.

"The design of the hydraulic part is indeed a difficult problem." Xie Jianguo nodded, hoping that his son would tell him how to calculate it.

Xie Kai looked at his father's expectant eyes and rolled his eyes, "Dad, I don't know how to calculate it, otherwise why would we need technicians?"

"By the way, there is also an operating system. This is different from a tank. You need to add a device to control the shovel arm..." After Xie Kai finished speaking, he hit the hatchet.

I looked up at the clock on the wall and saw that it was five o'clock.

"Dad, I can't bear it, I have to go to sleep. Don't think about it. We will organize a meeting tomorrow to discuss. Anyway, the structure of the excavator is just like this, not complicated. Research on the hydraulic system, and the hydraulic and support system of the mining machinery later.

There are also benefits, and it can even be used in the tank's gun stabilization system..." Xie Kai knows how important the hydraulic system will be in the future.

It goes deep into almost all automation fields.

The technical strength of Hongqi Machinery Factory is not bad. If we work hard in this area and accumulate rich experience, the road ahead will be broad.

"Don't rush to sleep. Let's talk about how to deal with the cockpit and combat compartment under the tank!" Xie Jianguo was a little confused. "If only the engine part is retained, the rotating part above will be difficult to place. If it is not removed, it will

Causing leaks..."

Xie Kai could hardly open his eyes.

In the past few days, he couldn't sleep well at all because of what happened with Baicai and how he could make his property safer.

Dad is used to staying up late and working overtime. He can persist without sleeping for several days, but he can't.

In addition, the body is still growing and has a higher need for sleep.

"Dad, how could the engineering Corps leak the secret? Besides, the tank chassis is just a chassis, which means the wheels on both sides plus a plate, and the excess part can be removed. If that doesn't work, put the engine on top of the rotating gear. But that way

I guess the engineers won't like it... Of course, the tank gun and turret, more than ten tons, can be driven by the rotating gear..." Xie Kai squinted and walked towards the room.

When Xie Jianguo heard this, he suddenly slapped his head.

That's true, just put the engine on it.

But then I thought about it, and Xie Kai was right. If the engineering troops don't want it installed, isn't this work in vain?
