The 1224 tank belongs to the first domestic tank prototype in line with the West, this tank, in the domestic technological development, is quite forward-looking, it first abandoned the cast turret for the first time, and replaced it with a welded structure.

If it was planned, the 1224 tank should have come out first, and the Storm Tank would have come out first, but in fact, due to the delay in the work of the R&D room, it was the Storm Tank that came out first.

The Storm Tank already has a prototype, which is also a welded turret, but compared with the two welded turrets, it can be found that the welded turret of the 1224 tank has a larger amount of work, and the welded polyhedron far exceeds the structure of the Storm Tank, especially the arc shape at the front, which is simply the first in China.

Thanks to the welded turret, the space inside the turret has become quite spacious, and the additional tail compartment at the tail is also prepared for the automatic loader.

It's just that the automatic loader has not yet been developed.

Qin Zhenhua looked at this tank that was being finally assembled and commissioned, and his heart fluctuated, after several twists and turns, this tank was still born in his own hands, father, did you see it? Son is making your wish come true step by step!

This tank, in fact, is his imagination of the future tank outlined in his father's notebook, and this imagination is finally coming true under his own hands.

Wang Erzhu is there, busy coming and going, as Qin Zhenhua's follower, Wang Erzhu is now able to pick up the girder, at least assemble according to the drawings, and at the same time eliminate some technical problems, he is still familiar with the road.

"Erzhuzi, hard work." Qin Zhenhua said.

"Brother Zhenhua, are you here? Hey, Zhang Gong, you're here too? Wang Erzhu saw Zhang Baolin with a strange look on his face.

Obviously, Wang Erzhu didn't care about what happened recently, after all, this tank was his biggest task at present, and all his thoughts were on this.

At the same time, this tank also embodies the most advanced technology in China, so the most reliable personnel are used, especially since these personnel have been in the factory since they entered the assembly, and even sleep in the temporary dormitory next to it, completely without communicating with the outside world.

If someone tries to spy on the real secrets of a machine factory, they are doomed to failure.

"The engine is in place?" Zhang Baolin asked Wang Erzhu: "What is the difference between this engine and ours?" ”

"It's big." Wang Erzhu said: "Therefore, the space we set aside for the engine compartment is large enough, and at the same time, although it has a large nominal power, it also needs a strong heat dissipation capacity. ”

The space occupied in the back is very large, on the one hand, because this engine is already large, on the other hand, because it requires a large radiator, and on the other hand, unlike the previous tank engine, it uses a longitudinal structure.

Just like a car, the front end of a premium car looks long, why? This is because the front of these cars are longitudinally mounted engines, while the front of ordinary cars is very short, and the engine inside is transverse.

It's the same with tanks.

In the past, tank engines were transverse, quite compact, and could also reduce weight, Soviet tanks have always been smaller than Western tanks, which is due to many reasons, and transverse engines are one of them.

As for the West, longitudinal engines have always been used, and the advantages of this longitudinal position are that it is convenient for the arrangement and replacement of the power pack, easy to maintain, and good service, which is conducive to the replacement of more advanced power packs in the future. The first thing to realize the overall hoisting is the longitudinal engine.

Of course, this is the result of many considerations, for example, the engine of the German Leopard 2 tank, which is probably square, so there is almost no difference between horizontal and vertical layouts.

Some engines are relatively long, and if they are stuffed horizontally, it will be beyond the width of the car body, so at this time, it will have to be longitudinal.

Longitudinal, in the current trend, is still more inclined to longitudinal engine, the introduction of German diesel engine, naturally adopted the longitudinal scheme.

"On the transmission system, we use a hydraulic torque converter with a fixed-shaft gearbox, of course, this is only in the early stage to reduce the difficulty, in the back, we are pre-researching a fully automatic gearbox, after all, this is the trend of the development of the tank power system." Qin Zhenhua said.

1224 tank, in the country is of cross-era significance, this tank in all aspects, has a fundamental change, take the power system as an example, it is intended to gradually become a fully automatic transmission, this is a major breakthrough, when the time comes, do not need to pull the operating lever, become a steering wheel steering, for the tanker, it is simply too friendly.

Even if it is an ordinary looking track, the tank in front of you is also using double-pin ear hook glue, and the track shoes that can be replaced with floor rubber blocks are essentially different from the previous tank. It can walk directly on concrete floors without worrying about damaging the ground.

Will the troops choose this tank as the standard tank of the future? At this time, Qin Zhenhua is still looking forward to it.

Of course, if you want to talk about the shortcomings, there are also shortcomings, this tank uses a 120 mm tank gun, and it is planned to use an automatic loader, but until now, the development of an automatic loader has been difficult.

After all, Qin Zhenhua is not an immortal, and it is impossible to overcome all technical problems, which takes time and accumulation.

Zhang Baolin's envious eyes, staring at the engine at the tail, Qin Zhenhua knew that he was only focusing on the engine now, and nothing else was interested.

Therefore, Qin Zhenhua also talked about the topic of engines.

"How's the progress of your self-developed X150 engine?" Qin Zhenhua asked Zhang Baolin.

After the engine meeting that year, the three families separated, each engaged in their own work, in their hearts, naturally they all thought that their own project was the most suitable. And since it happened today, Qin Zhenhua brought it up.

Among the three plans, the plan of the coal province diesel engine plant is the easiest, that is, it is to modify the existing engine on the basis of the only, I heard that after the plan was finalized, they built a prototype in a year.

Look at a machine factory, so far, it is still carrying out the basic research and development of a single cylinder, and the gap is very large.
