Hearing Qin Zhenhua's answer, Kartsev's face suddenly had a smile: "It's really you! That international tank ranking list, is it your trick?"
The contrast between the past and after was too big. Qin Zhenhua only felt a slap in his heart, and was shocked. Is this Russian going to cause trouble for me here?
Originally, Qin Zhenhua had a premonition when the other party recognized him, and he recognized him. The next discussion was probably largely about the specific technical aspects of the tank. Qin Zhenhua had already prepared many questions, all of which were
You can study with the other party.
Unexpectedly, the other party actually said this topic, which surprised him very much.
"Cough, cough." Qin Zhenhua coughed twice, and then went to see Nie Qianqian. This matter was completely controlled by Nie Qianqian. Should I push the matter to her? Nie Qianqian knows Russian and has been by her side just now, but now she turns her head
In the past, there was no one else to find, Nie Qianqian had disappeared.
"I'm afraid you have a misunderstanding about this matter." Qin Zhenhua said seriously: "We have also seen the international tank rankings. Overall, I personally think it is quite fair. After all, T-80 and T-72
Tanks only have a small amount of public information. If you compare them based on those information, you should be correct if you get such a list."
Looking at the other person's smile on his face, Qin Zhenhua also knew that the other person did not really take this matter seriously. After all, before the list came out, the relationship between the two countries had not eased? You didn't protest at that time?
, It's just a small complaint? Does Qin Zhenhua insist on the truth? I personally think it's okay.
"For example, take the engine as an example? If the current tank engine does not have a thousand horsepower, I am embarrassed to show it out? The engine used by the T-72 tank is only 780 horsepower, so it is naturally a bad one.
There was a piece of it." What Qin Zhenhua said has made many people look bad? We came here to visit, but we didn't come to slap in the face. What should we do if we quarrel with others in a while?
Qin Zhenhua didn't care and continued, "So, if you want to be on the top of the list? Then you have to come up with new equipment. Is the Soviet Union a big country? A military-industrial power, I don't believe that your 780-horsepower diesel engine has been used for ten times.
How many years have you not changed, now? Needless to say, 800 horsepower? I'm afraid that the 900 horsepower diesel engine has already been available? If you have good things, you can't cherish it yourself. Take it out and let everyone see it."
Not to mention anything else, first of all, from the power aspect, the T-72 is not qualified. Just now, Qin Zhenhua just wanted to use the tanks from the Molozov Design Bureau to put pressure on the other party. Now that the other party has raised this international
Tank rankings, let’s talk about it carefully, what are you embarrassed to take out? Good things, let everyone see!
If not, then I'm sorry, just that motivation, the ranking of you is already very good.
This was a stimulating word. Kartsev's face suddenly became richer. Okay, you little guy came to stimulate us. You students dare to run to the teacher's head.
Have you started to show off? Well, let's see the teacher's real skills.
Kartsev couldn't hold back.
"Of course we have the things you said," Kartsev said. "Wait, go to the engine test workshop, where we have improved the B-84 engine, and the power has been further increased to 840 horsepower."
After the other party said this, everyone else couldn't help but give Qin Zhenhua a thumbs up. The Soviets finally opened up some research and development areas for us to show them.
"This engine is a new supercharger that has improved the engine power to 840 horsepower, and it can also be increased to 880 horsepower if the lifespan is not considered." Kartsev said: "This one is a model that can be increased to 840 horsepower."
If power is used on the T-72 tank, the ton of power has exceeded the 20 horsepower per ton. How about it? Is it enough?"
The T-72 tank mainly uses a 780-horsepower diesel engine, which is also the power of the export version. However, the domestic version has always been improved. Now, by improving the supercharger device, the engine structure is optimized.
, after obtaining this improved engine, the power is nearly 900 horsepower, which is already quite powerful. After all, compared with tanks from other countries, the Soviet tanks did not weigh much.
Facing Kartsev's introduction, Qin Zhenhua still shook his head carelessly: "No, no, I think this is not enough. You have taken the wrong path."
Everyone was stunned again.
In front of us, the most important tank engineer in the Soviet Union! The Soviets were teachers and students. We came here to examine learning experience. Are you here to slap in the face?
"Wrong?" The expression on Kartsev's face was obviously ugly.
"Yes, I'm wrong. I think you have developed to 880 horsepower and the supercharger has also reached its peak. If you want to further increase the power, you have to use exhaust gas turbocharger."
Qin Zhenhua started to give advice and talk about it here.
Mechanical supercharger, for a long time, is the main way for the engine to increase power. It drives a supercharger through a belt on the engine, directly adding more air intake to the engine, which is quite direct, but at the same time, the weakness.
There are also some. Since it is driven by the engine, it will waste power.
Therefore, no matter how powerful the mechanical supercharger is, it is eventually replaced by turbocharger. The turbocharger uses the exhaust gas from the engine exhaust pipe, which is beneficial to improving the engine's power and thermal efficiency.
Therefore, the West has long eliminated mechanical supercharger and entered the turbocharger sequence.
His words were simply stomping on the other party. Everyone thought the other party would be angry. Who would have thought that the other party was solemn, but he didn't look angry: "Exhaust gas turbocharger?" Kartsev murmured
He said: "I didn't expect that the path you choose is better than ours."
This sentence actually echoed Qin Zhenhua!
The Soviet mechanical engineers were also quite capable, so now, they have found that using mechanical supercharger has come to an end. Their B-84 and B-88 engines are already at their limit, representing mechanical supercharger.
The highest level of the engine also represents the end of mechanical supercharger.
In their plan, the development of an exhaust gas turbocharged engine has begun. If the engine's foundation is to be able to be increased to 900 horsepower or even 1,000 horsepower, it can only rely on the turbocharged engine solution.
