"Old Xie, the management of your second machine factory is not strict enough. There is actually wine and peanuts in your office! You said, if it is spread, what will happen if you drink secretly when you are at work?"
Qin Zhenhua smiled and held the wine glass, put the sip of wine into his stomach, then grabbed the peanuts with his hands and threw them into his mouth, and said while eating.
"I'm not drinking during work. When I work overtime at night, I can't hold on anymore, so I'll take a few sips. Hey, you kid, don't behave like a cheap person. This is Moutai!"
That’s right, there are several bottles of wine in Xie Huimin’s desk. The bottle he took out now is Moutai! When he went abroad and came back, when he got off the plane, everyone would give him a bottle of Moutai and Qin Zhenhua’s bottle.
I drank it all when I came back, and Xie Huimin's bottle has been treasured until now, and I took it out and shared it with Qin Zhenhua, which is enough to reflect my importance to Qin Zhenhua.
Everyone loves to drink on the grassland. After all, it is cold and cold. This drinking is the best way to regulate, to warm the body.
Now, after a glass of wine, it was warm inside. Xie Huimin said, "Okay, you can continue to talk about the overall idea? Our second machine factory is a cannon manufacturer, and we are not very familiar with the whole vehicle."
The second machine factory is mainly responsible for making artillery. If you want to make artillery, they dare to say second, but no one dares to say first, but building a complete vehicle is different. If you want to make a complete vehicle, it is of course the first machine factory’s best.
It's right.
Is it integrated into the chassis of the 59 tank? How to integrate it specifically? Of course, the technician of the First Machine Factory came to speak. In this regard, the First Machine Factory is the most experienced.
"Old Xie, you are so kind of a noble man who forgets the trouble. Have you forgotten the 152mm self-propelled howitzer project? How about that chassis?" Qin Zhenhua said: "It's the 321 chassis!"
In the self-propelled chassis, the country has also experienced some twists and turns. As weapons begin to develop in the direction of self-propelled, various domestic towing artillery have also begun to move closer toward self-propelled.
Self-development is time-consuming. A common practice is to use existing ones to modify them, so it is often called universal chassis. In fact, this is a compromise that some middle-class countries cannot independently develop.
If you need to use self-propelled artillery, let’s take a look at what can meet the needs and use what to develop.
At that time, looking around, the Type 63 armored conveyor vehicle that could be used in China was developed based on this type of armored conveyor vehicle.
However, the Type 63 armored vehicle is a small armored vehicle with only four pairs of heavy wheels. When carrying such a 122mm caliber howitzer immediately turned into a big head, so although it was modified, it was actually not qualified.
.
Especially after the 122mm howitzer project was completed, the country began to develop a 152mm caliber howitzer. This kind of howitzer cannot be assembled on the chassis of the 63 armored vehicle in any case. This requires a special chassis to be developed.
.
That's right, this medium-sized artillery universal chassis code-named 321 was originally developed for the 152mm self-propelled howitzer as a supporting project. This project started in 1970, and the first prototype was also launched in 1978.
Now, four or five years have passed, how could the Second Machine Factory not familiar with this chassis?
In fact, there are many reasons for this. Now, after hearing Qin Zhenhua say this, Xie Huimin couldn't help but start to complain.
Generally speaking, the research and development of normal self-propelled artillery should be mainly based on artillery factories, but it is different in China. The domestic integrated terminal manufacturer of self-propelled artillery systems is not an artillery factory, but a chassis manufacturer!
Therefore, this 152mm self-propelled howitzer was not built in the second machine factory, but was developed in a related factory in Bingcheng.
"The Bingcheng Factory used to develop the Type 62 light tank. A few years ago, after the self-propelled howitzer project was launched, the Bingcheng Factory applied for this project to the country. It has been more than ten years since then, and the chassis they produced, and the problem is that
Continuously, although I have been hearing that it is going to be finalized recently, we really can't feel at ease on the chassis." Xie Huimin said: "This project is still a national key project, with sufficient financial support, and we need to use it ourselves.
This 321 medium-sized chassis requires self-raised funds. After all, the country's military expenditure is tight and it is impossible to allocate funds to this failed project. If we ask us to cooperate with the Ice City Factory, we may have a lot of inconvenience.
"Xie Huimin began to spit.
In the past, all projects were allocated by the state. The Second Machine Factory built guns. This 152mm self-propelled howitzer project actually has nothing to do with the Second Machine Factory. They built howitzers, how to install them, etc.
It is all the people in charge of the Ice City Factory.
The chassis is unreliable. They have heard of it. The project has been experimenting, but it has never been successful. Now, can their 120mm tank gun be installed on that kind of chassis?
Xie Huimin knew the technical strength of the Ice City Factory clearly, so now, when he heard Qin Zhenhua say this, he immediately began to hesitate.
"Unreliable?" Qin Zhenhua was very surprised: "Don't all the chassis use existing finished products? What else is unreliable?"
This medium-sized chassis, code-named 321, actually uses various existing technologies. For example, its engine actually uses a 520-horsepower tank engine!
However, in order to meet the requirements of the use of self-propelled artillery, the engine was not deployed at the back of the vehicle body like an ordinary tank, but was deployed at the front. On the right side of the vehicle body, the engine was arranged and the cab was arranged on the left side.
, the same as the arrangement of the Mekawa tanks in Israel.
In this way, all the problems were solved in the front, and the huge space behind was prepared for self-propelled artillery.
The components are the existing components of domestic tank and armored vehicles, engines, gearboxes, transmission gears, etc., and there is no difference. The only thing is that the driving wheel is in front. Under the body, six pairs of medium-diameter load-bearing wheels are used.
At the same time, a sufficient distance is spaced apart, with three pulleys on it, and thus an elongated car body is formed.
Qin Zhenhua has learned about this chassis. In theory, there is no problem with the overall design. What other technical problems can arise?
"If you want to talk about the country, your machine factory has the strongest R&D strength." Xie Huimin said: "If it were in your hands, this kind of chassis would have matured long ago, but the technology on the Ice City Factory
The strength is too weak, and many small problems will be studied for a long time. If we install a 120mm tank gun on this kind of chassis, we still don’t know the Year of the Monkey and Horse Month.”
