Qin Zhenhua didn't pay much attention to this matter, after all, he had a lot of things to do, so he quickly put this matter behind him, began to enter his own work state, and left for a few months, there are many things he needs to ask about in the factory, and there are many things that need to be arranged.

To say that the most urgent of them still belongs to the 155-mm self-propelled howitzer project, this self-propelled howitzer wants to win foreign orders, then it has to be quickly hammered out, especially, in addition to self-propelled howitzers, there are also supporting ammunition supply vehicles, and even, the latter is more important.

This project was handed over to Luo Rongchang to be responsible, and the masters who were in the maintenance workshop of a machine factory back then have now been reused and have become the leaders of various projects, Qin Zhenhua is not embarrassed by this arrangement.

They were originally a group of hard-working teachers, diligent and diligent, and later, after Qin Zhenhua began to give lectures at night, everyone also followed suit, had practice, and had a lot of theoretical knowledge, and quickly grew into qualified expert-level talents.

Then, naturally, you will be able to take charge of various departments.

University student?

That's right, some college students are very powerful, but, some, after thousands of troops crossed the single-plank bridge, they thought it was time to rest, anyway, the future is bright, in short, people who mess around can't live in a machine factory.

On this day, Luo Rongchang came to Qin Zhenhua again.

Now the domestic maturity is the 321 medium-sized universal chassis, so whether it is a self-propelled howitzer or a bomb supply vehicle, this chassis is used, and the self-propelled howitzer has been almost done at the second machine factory, mainly for the bomb supply vehicle.

"The biggest difficulty in the design of this ammunition supply vehicle is not how to automatically reload ammunition." Luo Ronggen said to Qin Zhenhua: "After repeated research, we believe that the most important thing is safety. ”

This point is also easy for many people to ignore, this 155 mm caliber self-propelled howitzer, mainly with grenades, grenade warheads, are high explosives, as well as propellants, are also high-energy, it can be said that a bomb supply vehicle, which can be loaded with ninety warheads and propellants, this is a small ammunition depot.

If the cannon inside malfunctioned and exploded, the consequences would be absolutely unimaginable.

Qin Zhenhua nodded: "That's right, security should be put first." ”

"So, after thinking about it, we decided to carry out special safety settings inside, especially in each compartment, there is a special temperature detection device." Luo Rongchang introduced.

At the time of design, it was planned to dock the vehicle upside down, because of this special ammunition supply vehicle, the ammunition magazine was planned to be set at the rear.

After all, the driving and engine of this 321 universal chassis are vacant in the front, the middle and rear are vacant, and in these compartments it is possible to set up a special cuboid ammunition compartment.

Now, Luo Rongchang has made a special plan with a team.

The front part of the ammunition compartment is the warhead area, and in order to facilitate the automatic and rapid selection and retrieval of ammunition by the ammunition feeder, it is planned to use ten cartridge reusable warhead boxes stacked in the projectile area, and each warhead box can hold 9 warheads. That's exactly ninety.

As a howitzer, it is equipped with different warheads, for example, the current 155 mm howitzer has six warheads, eight charges and four fuses, so it is necessary to carry warheads, propellants and fuses in different proportions according to the battlefield situation in advance.

Moreover, in such a way, it is also convenient to replenish it in the future, and it is enough to directly lift the ammunition box.

As for the propellant packs, they are placed on both sides of the bomb carrier at the rear of the ammunition compartment, and the storage mechanism is a compartment type, and each ammunition is packaged in a compartment.

"It's better to have a computer monitoring device up there." Listening to Luo Rongchang's introduction, Qin Zhenhua said: "This can also show that our equipment is high." ”

Computer monitoring? Luo Rongchang frowned: "In that case, the difficulty of research and development will increase, and the important thing is that the cost will increase a lot." ”

Our export products mainly rely on good quality and low price.

However, this time Qin Zhenhua shook his head: "Our target customers are big financiers, the price issue is secondary, the technology must be advanced, and the products must be high." As for technical matters, please cooperate with our computer center. ”

Different customers, the needs are different, some are cheap, some are performance, this time the exporting country, what is important is the performance, and people are not bad for money.

After flipping the table last time, those college students in the computer center should also be at ease, right? The factory gave them tasks, which was to reuse them, and they would definitely not dare to grind foreign workers anymore.

Luo Rongchang nodded, in this case, it can also be joined, and if it is controlled by a computer, it should be better.

"On the other hand, we plan to replace the original 12150L diesel engine with BF12L.413FC air-cooled supercharged intercooled diesel engine." Luo Rongchang said: "This engine has been able to output more than 500 horsepower, and compared with the original diesel engine, the life has increased by more than ten times. ”

This 321 chassis, in the years of research and development, there is nothing to choose from, can only use the same 12150 diesel engine as the 59 tank, this diesel engine is strong and durable, quite mature, but the life is quite short, five hundred hours need to be overhauled.

Later, a machine factory replaced some parts and increased the service life, but even then, it was only a thousand hours.

They are used to it, it doesn't matter, and even some grassroots units have the ability to overhaul, but foreign users are different, if they know the equipment in their hands, the diesel engine will be scrapped in 1,000 hours, I don't know how they will feel.

Therefore, it must be replaced, and Deutz has exported their air-cooled diesel engine technology to the eastern powers, and in the diesel engine factories of the eastern powers, the manufacturing process has also been completed and has matured.

More importantly, this diesel engine factory was also acquired by a machine factory and became a subordinate enterprise of a machine factory, so it should be done.

Qin Zhenhua nodded: "This is okay, but you must pay attention to the problem of heat dissipation, and you must not drop the chain on this." ”

In terms of heat dissipation, the air-cooled diesel engine is naturally weaker than the water-cooled one, and in the desert area, it is hot inside, and the wind blowing over is hot, this problem is even more serious, if this problem cannot be solved, it will leave a bad impression on the user.

"Don't worry, we have experience." Luo Rongchang said: "We use forced heat dissipation, the original space is large enough, let's make a special heat dissipation air duct, we will be able to properly solve it." ”

As he was talking, the phone rang, Qin Zhenhua picked up the phone, and suddenly his face was happy: "What? Director Zhao is back? And brought in new customers, well, we'll be ready on our side. ”
