Now Qin Zhenhua has no other choice.

Our current 59 tanks, 69 tanks, and even even the tanks modified from the L7 tank guns introduced by the replacement, are all first-generation tanks with 5 pairs of load-bearing wheels, which limits the potential for further development of the tank, so it is necessary to use a larger chassis and more advanced engines to meet the needs of the future, which is the second-generation tank.

The 122 tank has been studied for many years, but the above technologies cannot be matured because of their weak industrial base, and their new second-generation tank project needs to be built on the basis of the 122 tank, but it is necessary to use mature technology as much as possible.

Not to mention anything else, take the engine as an example, there is nothing to use at hand now, and the tank engines in our current plan will take many years to really mature, and the second-generation tank project is already imminent.

Are there any other good options?

Even if the 8V331 engine is relatively large, it is still a civilian engine, after all, it is an engine with a power of 1000 horsepower! Now, which domestic engine can compare?

Therefore, after coming back last time, Qin Zhenhua modified his own design plan, specifically for the size of the 8V331 engine, etc., and made adaptive supporting modifications, because this is a civilian model, it is not as ruthless as the squeezing power, and there is no need to have a super radiator, so, in terms of overall volume, it is still acceptable, and it is no problem to stuff it into the butt of its second-generation tank.

And now, seeing that the time is still early, just like a teacher who likes to drag the hall, Qin Zhenhua started his own introduction again.

Actually, this is the content of tomorrow's meeting, but I can't help it today, and I just catch up with this opportunity, so Qin Zhenhua plans to seize everyone's time.

Opportunities are all fought for, when I was in a machine factory, after I went abroad, and now, naturally.

"With German engines, matched to our second-generation tanks?" After hearing Qin Zhenhua's introduction, Xiang Dayang suddenly showed interest, yes, of course he was interested.

At this meeting, the most important thing is the project plan of the second-generation tank, and now, the research and development of the diesel engine just talked about is because this is a short board in China, and it is also a focus of this overseas investigation.

Now, Qin Zhenhua said this, which means that their surveying and mapping imitation project will be more justified, and after it comes out, it will directly match our second-generation tank!

"Yes, it is." Qin Zhenhua replied to Xiang Dayang's words, at this time, this old expert no longer had the kind of dissatisfaction that Qin Zhenhua questioned, it was simply glorious.

"Leaders, can you listen to him first? I'm afraid that after the meeting is dismissed, I still want to ask him, which will be a violation of discipline, and if I don't listen, I won't be able to sleep that night. Xiang Dayang said.

As a veteran in the industry, as soon as he opened his mouth like this, it was still early, and naturally, the leader had no opinion.

"Well, then I'll introduce, we know that in the past, the 122 experimental prototype car was developed." Qin Zhenhua said: "At that time, the index was very high, the three-liquid prototype car, because the technology was not up to par, and finally gave up, and now, we are going to use the existing technology to complete our second-generation tank research and development as soon as possible. ”

With Qin Zhenhua's words, Wang Erzhu vigorously moved a cardboard box under his feet, this box was moved after eating at noon, and everyone didn't pay attention to it at that time, but now, they can see that the door is coming.

Qin Zhenhua had long known that he might lose the bidding for the engine, so the focus of his attention in the afternoon was no longer the engine, but the research and development of the second-generation tank!

Tank research and development can be the business of the tank design institute, or it can be the task of a machine factory, and in the research and development of diesel engines, whether it is dominated by the engine factory or the engine is the focus of the dispute.

Now, Qin Zhenhua is a project that he grabbed from tank design.

Wang Erzhu opened the box and grabbed thick documents from it, and at this time, the service staff in the conference room also helped him and sent the documents inside to the hands of the main leaders.

Minister Zhu took it, there were about 50 pieces of paper in it, which were printed and bound in the printing room, especially the light blue drawings among them, which were neatly folded, so he unfolded the drawings with great interest and spread them on the table, and the overall design of a tank appeared in front of him.

1224 experimental prototype.

The most striking thing is its turret.

At present, the turret of all domestic tanks is cast in the shape of an eggshell, which can form a good bullet-proof shape, but the disadvantage is that composite armor cannot be installed, so the mainstream tanks in the West have begun to use welded turrets.

On the 122 experimental prototype, the traditional cast turret is still used, and now, this 1224 experimental prototype is already a beautiful welded turret.

This turret looks relatively large in size and slightly flattened in shape, compared with the previous hemispherical turret, the internal space can definitely become a lot larger, and the front of the turret is a kind of arc-shaped smooth transition, which looks different from any kind of turret in the world, it seems to be quite painstaking.

This drawing is the most suitable perspective view, and you can also see the interior design, and even all kinds of data are marked on it.

Its chassis, a synthesis of the previous 122 three-liquid prototype, uses six pairs of small-diameter load-bearing wheels, which is in stark contrast to the previous 59 tank chassis, on the whole, this tank has a new look, with a clear Western color.

"For our tank, we plan to use a new turret welded from special steel plates, which not only makes the turret spacious inside, but also has better ergonomics. Moreover, there is room for improvement in many aspects, for example, the rear of the turret has a large enough aft compartment to install an automatic loader, and in the front of the turret, the structure of the unit can be disassembled, and the composite deck can be replaced when needed, so as to enhance the frontal protection..."

Qin Zhenhua introduced, this tank is also a project planned in his father's notebook, and now, it is finally useful.
