1223 experimental prototype.

"Let's look at its turret first, the turret of this tank, using our existing 69 tank turret, on which a 105 mm tank gun imported from the United Kingdom is installed, and its fire control system also adopts products imported from the United Kingdom, because there is already a modified tank, so in terms of turret and firepower, we should not have too many problems."

It's already the second day, and this day's meeting is the research and development of the second-generation tank, and this project was originally the focus of this meeting, so the estimated time is also the longest, and the report of the first machine factory is also extremely detailed.

Before reporting in detail on yesterday's 1224 project, Qin Zhenhua first reported on the 1223 project.

This project is definitely the most mature solution, because it uses almost everything that can be used now, and there will be no immature technology in it, which means that its research and development will hardly fail due to major problems, and the 1224 project is almost the two extremes.

It is too conservative, conservative is not like a young innovative technician like Qin Zhenhua proposed a project, but like a project proposed by an old man who is about to retire and has worked in the post all his life.

This makes many people have a strange feeling, Qin Zhenhua is playing with words, originally just planned to engage in the second-generation main battle tank, but Qin Zhenhua is here, directly made a series, all kinds of designs, conservative, advanced, safe, leading, so much, how did he push it, and this introduction manual is so real in his hand.

Today, they have brought in several large boxes, and it is already their turn to have one.

"Looking at its chassis next, we still use the research results of the existing 122 tank to use the chassis design of six pairs of load-bearing wheels, which can also have more space." Qin Zhenhua continued: "As for its engine, we plan to use the 537 kilowatt engine developed by the Coal Provincial Diesel Engine Plant. Yesterday, I had already met with the technicians of the Coal Provincial Diesel Engine Plant, and they promised that they would not drop the chain for us, and that they would deliver the qualified engines to us when our tanks were assembled. ”

The 122 tank of the year was a failed project, and it was immature in all aspects, if the only desirable place was the overall design of the chassis, the space was relatively large, so it was easy to match, and it was possible to stuff the German 8V331 engine into it, and it was also possible to stuff the improved model of its own 12150L engine into it.

"Of course, considering that the power of this engine is still not very sufficient, we plan to limit the weight of the entire tank to about 38 tons, so that it can be improved compared with the existing tank." Qin Zhenhua said: "Of course, if the Coal Provincial Diesel Engine Factory can take out the 735 kilowatt engine they planned yesterday, then we will welcome it even more." ”

Yesterday, the Coal Provincial Diesel Engine Plant suffered a loss, originally today everyone thought that in this second-generation tank project, the Coal Provincial Diesel Engine Factory would be in opposition, after all, everyone is within the system, and they all have the right to speak, if they strongly oppose it, that engine factory will also be in trouble.

Where did I think that the 1223 project that Qin Zhenhua briefly introduced in two sentences yesterday has already taken into account the interests of the diesel engine factory in the coal province.

Their diesel engine also has a place for it, and it is also the engine that they are now about to complete their research and development!

"At the same time, when we design, we also left enough leeway, and when we waited for the power to increase and the dead weight could come up, we could hang more armor on the outside of the tank to enhance protection, as for the present, combined with our current situation, when we consider three major factors, the first is firepower, and then mobility, and protection can only be put last."

The three major indicators of tank design, firepower, mobility, and protection, if it is a Western country, these three indicators should be balanced, if they cannot all be met, then, the first thing they focus on is definitely protection, after all, they are afraid of the dead, and their lives are worth their money.

For example, the Challenger tank puts protection first.

As for the firepower, in fact, people have never been bad.

The domestic situation is different, for a long time, the domestic main battle tanks did not even have the ability to tear through the enemy's main armor, and rushed up to it was a bunch of burning sticks, and only by going around to the side or behind would there be a chance, in this case, what maneuvering, protection, can only be placed in the back, and the priority is firepower.

Therefore, in Qin Zhenhua's carefully protected diary, there is a saying that tanks and firepower are king.

Tanks are weapons, and first of all, they need to be able to fight the enemy.

Under this premise, protection and maneuverability will be taken into account, which are closely related to the engine.

The power of the engine is insufficient, the weight of the tank can not be too high, otherwise it will not be able to move, and the engine, which is related to the entire industrial base, has increased the 500 horsepower of the 59 tank engine to the current 730 horsepower, which is already a lot of effort, and such power, it is impossible to push the tank with too much weight, 38 tons is already the limit.

This is a conservative program, but it is the easiest plan to succeed, at this time, this tank program, codenamed 1223, no one has yet realized that it will be finalized, and finally equip the troops, becoming the basic equipment of the second-generation tank in China.

"This model, and yesterday's model, there are a lot of differences, your machine factory, do you have the strength to develop this?" Just after Qin Zhenhua finished introducing the 1223 project, one of the leaders above spoke: "Moreover, will this waste a lot of money?" ”

After all, the country is still poor, in the engine, can only support one model, now, a machine factory has reported two models, whether it is developed together, or only one model, that must be considered clearly.

"Please look here." As if knowing the leader's question, Qin Zhenhua held a slide film in his hand and put it on the slide projector: "This is the design drawing of our 1223 tank project." ”

Then, I took it down and put another one: "This is the blueprint of our 1224 tank project." ”

Then, Qin Zhenhua stacked the two films together and put them on top: "Now, please look at it." ”

The two sheets of film are stacked on top of each other, and you can see that most of the outlines are perfectly overlapped.

"As you can see, in fact, this is just two different configurations of one model, in the words of foreign trends, this is called modularization. Therefore, research and development will not cause repetitive waste at all, and will only make our project research and development more secure. ”
