The first thousand three hundred and fifty-seven chapters are not taxable for bragging
It is not easy to achieve the power required by the third generation of tanks, so all kinds of weird designs are endless. The French are taking the road of combining turbine engines and diesel engines, while the islanders take the road of two-stroke engines.
, and the Soviets, later on, actually embarked on the road of X-type engine. Of course, by the time this engine really came out, it was no longer the Soviet Union, but Russia.
However, the design idea of this kind of engine has begun to sprout from now on. After all, the planning for engine power improvement has started very early.
Now, Kartsev heard Qin Zhenhua talk about the X-type engine and began to think about it seriously.
Now, their V-shaped engine has an angle of 60 degrees. For X-shaped engines, the V-shaped upper and V-shaped lower inverted V-shaped lower are both 120 degrees. In this case, it is equivalent to
The two engines are connected together, but the overall height is not much higher than the existing engine. In this way, they should still be installed in the existing engine compartment.
They value this very much. After all, if you want to increase the distance between the cylinder centers without changing the length of the engine, then stacking the engine up and down like this should be the most suitable solution, which is simply perfect
Solve the problem of engine size increasing due to the lengthening of cylinder center distance. As long as the engine volume does not expand, the body can still remain compact. For them? This is crucial? Because it means
After a simple upgrade of existing tanks, they can adapt to future development needs.
"Of course, this layout has some disadvantages. The biggest problem is that after the engine stops running, the oil is poured back to the cylinder below? The problem of burning oil and carbon deposits that ultimately lead to is not impossible to solve?
Besides? For tank engines? These are not problems."
Other engines? Are the cylinder pistons on top? Are the crankshaft and oil shell on bottom? In this way, as long as the oil tank is well ventilated and the internal pressure is not too high, it will not jump to the top. Many turbocharged engines in later generations burn oil?
Is that because the matching problem of supercharged intercooling is not done well? Is the pressure in the crankcase too high? The oil rushed into the inside of the cylinder and burned.
For the current X-type engine, the two cylinders below are upside down, so after stopping operation, the oil under gravity flows downward and flows into the two cylinders below, which is a very serious problem.
.
This problem is difficult to solve, but tank engines can last for hundreds of hours. At worst, overhaul engines will not be a problem. Soviet weapons and equipment have always paid attention to consumables on the battlefield.
A hundred hours are enough.
Anyway, Qin Zhenhua was full of words and said that he was running a train, introducing new concepts to others, fooling others, and satisfying himself. It can be said that there are benefits but no harm. He himself said whatever he wanted, and now Kartsev is obviously
Very interested.
After talking about the advantages and disadvantages, Kartsev nodded to Qin Zhenhua repeatedly: "I really didn't expect that your understanding of tank engines is so deep. Are you studying this X-shaped engine?"
This question made Qin Zhenhua feel a little ashamed. Research? We don’t have that level. We have been working in China for decades, but we are just digging deeper on the basis of the B-2 diesel engine. If we develop a brand new diesel engine
, Where can we have this strength!
"We have this plan, but following the current path, we can already achieve the power demand of 1,200 horsepower. Therefore, we do not have too urgent needs for new power, so it is just pre-research."
Qin Zhenhua continued shamelessly.
We are pre-research, what about the results of pre-research? In my mind, what about the pre-research team? It’s myself. When did it start? It’s just now.
Kartsev nodded and did not continue. However, he was obviously worried.
As a tank designer, he has spent his whole life on tank research and development. Naturally, he can see the achievements made by the great powers of the East over the years. After opening their doors, they learned from the West and studied a lot of things.
Good stuff.
The tour of the engine factory was over, and then he went to the tank assembly plant. At this time, among the crowd, Qin Zhenhua was already walking side by side with Kartsev to give advice.
So far, the sales of T-72 are still very popular. They use it in the Soviet Union and need to be replaced continuously. There are still many orders outside, so their production lines are constantly being produced.
Looking at the chassis with V-shaped waveproof boards, Qin Zhenhua thought of the 123 tank prototype that was currently being tested in China. He felt a little emotional in his heart. Finally, he came to the T-72 tank manufacturer and came here to take a look.
The Soviet tank production line is really not easy.
"We found that the Eastern powers also adopted the caliber of 125mm as the standard for tank guns, which made us a little curious. Why did you not move closer to the West and use the caliber of 120mm, but took our path and used 125mm
Where is the tank gun?" Kartsev continued.
At this time, the atmosphere of the visit is very friendly, but in the friendship, you can also feel some of the purposes it carries.
The Soviets were surprised by the achievements made by the great powers in the years, so they were also talking to the great powers of the great powers. When the tank guns of the great powers were displayed, they reached 500 mm in depth, which surprised the Soviet Union quite a lot.
This is still the foreign trade version, and the version they use for themselves must be even more powerful.
Now, we are coming to the front of a tank that was installed. The turret is slowly lifted through the sky truck above our heads. The barrel on the turret is high and looks very powerful.
If you adopt the same caliber, you can be big or small. If you are small, you are just willing. If I choose, I like it, and if you are big, it is a matter of standing up.
The same caliber is conducive to replenishing ammunition on the battlefield, so the same camp will adopt the same caliber. The Eastern powers abandoned the Western caliber standards and adopted the Soviet caliber standards. What do you think?
"Tanks, firepower is the king." Qin Zhenhua said: "What we like is the cannon barrel. The larger the caliber, the better. Not only 125mm, we are even pre-researching the next generation of 140mm gun barrels."
What's there to say about this? The thicker the barrel, the stronger the performance. Moreover, just like just now, quickly put aside the current equipment situation to prevent leaks, and then talk nonsense.
