The first thousand three hundred and fifty-six chapters full of mouth running the train
Since industrialization, the great powers of the East have been almost always surveying and mapping, and there is basically no forward research and development. Although the Soviets also surveying and mapping were also surveying and mapping when they started, they have been forward research and development since then. The B-2 engine was created by the Soviets.
, People have already learned this engine thoroughly, so changing only one of them has been improved to this level of power.
In the team, experts who have been studying tank engines for a lifetime were shocked and moved.
It's not possible for us to do it, but the Russians can do it.
Of course, they don't want to change it either.
The cylinder center distance is related to the overall length of the engine. The 85 tanks on our side, or the third generation tank, use longitudinal engines. The engine is longer, but the vehicle body is longer. This is enough. However, the T-72 tank
It is a horizontal engine. If the engine is long, it means that the body of the vehicle needs to be widened.
The Russians don’t want to widen the body of the car, nor do they want to change the layout of the engine, because there are too many things involved, and one change is a major change, which is similar to redesigning a new tank.
In order not to change the tank, we have to toss and try our best to squeeze out the potential of the engine. As for reducing the engine's stroke, this can just reduce the engine's height, so it is useful.
It takes a lot of process to design an engine. At the beginning, of course, you have to choose the technical route. This 1,200-horsepower diesel engine in Kartsev's mouth is of course just a design idea now, but
, Just this idea? Is it quite not simple? It shows that the Russians have this confidence. Without changing the distance between the cylinder cores, the power will be increased to the limit of 1,200 horsepower.
I wonder what Mr. Zhu would feel if he heard it? The 123 tank in China is currently being tested? If he replaces the planned engine of the Russian, the tank body? Maybe it can be shortened by half a meter?
Even one meter, if this is the case, it can save two or three tons of weight, and then increase the weight to the protection of the vehicle body? Wouldn't it be cool?
Of course? Envy is useless. After all, the Soviets have not really started yet, but the domestic ones have already entered the test run stage. From this perspective, solve the problem of existence or not? There is no doubt that it is correct.
.
As for the engine size issue, look at the Western engines? You can know that your own size is actually very small.
"If the cylinder center distance is increased, will the engine volume be increased? We can't put it into the existing engine compartment." Kartsev said: "So, if we continue to plan a new engine? We are really
It's a headache."
The characteristics of the Soviet tank? The engine compartment is very small? The engine must be compact. If it were not for compactness, the T-64 tank would not use twin-cylinder-opposed engines. Moreover, people have now successfully increased the engine's power.
It's over 1,000 horsepower, but there is still a long way to go here.
In the plan, the maximum is 1,200 horsepower. I don’t know how many problems need to be solved, but this has reached its limit after all. Next, it is very troublesome to continue to increase your motivation.
The cylinder center distance needs to be increased, and the engine size cannot be changed. This is simply an unsolvable problem. Are they really going to stop at this power level?
"Don't you have a gas turbine?" Qin Zhenhua mentioned.
Here, the other party can reveal how much it is. In order to obtain enough power in a small engine compartment, the Soviets had already begun to try gas turbines, and the power had already exceeded 1,000 horsepower.
When Kartsev heard Qin Zhenhua mention the gas turbine, he changed his face and was quite unhappy: "That was just Nikola's mistake. It is not suitable for tanks to be equipped with gas turbines."
In fact, the test of gas turbines has been starting long ago. Since 1949, the Leningrad Kirov factory has been tinkering with that set of things. However, after studying for 20 or 30 years, there have been no good results. There are too many shortcomings of gas turbines.
, It was not suitable at all, but at that time, news came that American tanks had to use gas turbines. In the equipment sequence of the Soviet army, the United States had always had whatever the Soviet Union had, so the general design at that time
The division Nikola Sergeevich used the American choice to successfully convince the national leaders to agree to the T-80 tanks that use gas turbines to set up the troops.
Compared with the mass-produced T-64A tank and T-72 tank, this latest numbered tank has not improved much firepower, protection performance and maneuverability, but its fuel consumption has increased significantly and has entered the army for service.
Afterwards, the comparison data is also clear that the fuel consumption of T-80B and T-80BV tanks during marching motorcycles is four times that of T-72B tanks. Moreover, the fuel burns is still aviation fuel!
I really don’t know what those guys think, that clown Nichola did a big bad thing!
Kartsev felt very unhappy when he thought of this, but if you feel disgusted, it must be from the Molozov Design Bureau. The T-64 tank they designed was installed by the Kirov factory.
The gas turbine turned into a T-80 tank, and the Morozov Design Bureau was the most disadvantageous.
Now, his face is not good-looking, it is not just dissatisfaction with Qin Zhenhua, but just dissatisfaction with the gas turbine.
"Increasing the cylinder center distance cannot change the engine size." Qin Zhenhua started to give advice to the other party again: "I said, how about changing it to an X-type engine?"
In order to increase power and improve smoothness, one cylinder is definitely not good. The tractor is a single-cylinder engine, and the noise is loud. If you want to make the engine's power stable output, you must at least have a four-cylinder engine. However, for the tank
The output power of the four-cylinder engine is far from meeting the needs, and it also requires at least eight cylinders, or 12 commonly used cylinders.
If these cylinders are arranged in a straight line, the engine will be super long. Therefore, generally speaking, engines with more than six cylinders use V-shaped structures, with the cylinders tilted to both sides, and the connecting rods are intertwined and connected to the crankshaft.
This can greatly shorten the size of the engine. Now that you use the V12 engine, this is the layout.
The X-shaped engine is equivalent to two V-shaped ones stacked together, and the tips overlap. Looking at the letter, you can understand the shape of this engine. For example, an X12 engine is equivalent to two 120-degree angles.
The V6 engine stacks up and down.
In this way, just like a V-type engine with higher official strength than an inline engine, an X-type engine can also greatly increase the cylinder core distance under a limited volume.
Taking this route is an option.
Qin Zhenhua started running the train again. Wu Ruihua, who was beside him, shook his head helplessly. When did you hear of the X-type engine? It was only used during World War II.
Who would have thought that Kartsev's eyes were really lit: "The X-type engine? It sounds very good."
