The tank started to move back with a rumbling sound. After stopping, there was already one more person on the ground.
That person was not wearing a uniform. After all, those who were in charge of intelligence often had to disguise themselves. Therefore, the few people who came down from the tank were still unclear who the person who came was.
"How do we feel about our tank?" Dulaba asked Wang Erzhu, his eyes full of anticipation.
At the beginning, Wang Erzhu wanted to test drive the T-80, so Dulaba brought them over, which made them feel good. He fired more than a dozen tank guns, and finished all the coaches' bullets.
, If you want to consume, this round trip will cost more than 100,000 yuan.
In this way, you should be satisfied, right?
Wang Erzhu shook his head: "No, although the horsepower of this tank engine is enough, the speed is too slow. This level of opposite engine is indeed not good."
Wang Erzhu actually said this?
Hearing this, Duraba's face suddenly looked a little ugly. Saying these words was simply slapping them in the face of the Morozov Design Bureau. You know, the Morozov Design Bureau relied on this for making a living, and used it
It was equipped with the T-64. Later, after the job was snatched away by the Kirov factory, it snatched back with a diesel engine of 1,000 horsepower. Now, Wang Erzhu actually said that this engine is not good, which is really uncomfortable.
"Erzhuzi, how do you talk?" Qin Zhenhua quickly educated him: "They use a two-stroke engine, which was originally intended to get strong power. I think you must not drive it."
Qin Zhenhua was naturally talking slander. The two of them were so aggressive? So Du Laba's expression became a little dim.
"Yes, this horizontally opposed two-stroke diesel engine is flawed? But? It's already the best choice for the T-80 tank," Duraba explained.
At the beginning, two-stroke engines were used to achieve the need to increase power. At the same time, it was also because the horizontally opposed engines must be two-stroke, otherwise, the valves on the top of the piston could not be arranged at all.
However? This engine has not matured for a long time? It has been malfunctioning continuously? It has become a source of nightmare after the T-64 tank equipment troops.
Two-stroke engine? There are many defects.
During the ventilation process, some of the gas will be consumed. In addition, other reasons will cause its fuel consumption to be much higher than that of four-stroke engines under the same conditions, and will not have the effect of fuel saving.
Of course, compared to gas turbines? It is definitely a waste of money.
Its engine oil is injected with fuel? Will the engine oil be consumed? At the same time, because the cylinders are always in a very hot state, the carbon deposit problem inside the cylinder will become more serious? And so on.
These shortcomings all plague this engine, so for the Morozov Design Bureau, they had actually had thoughts for a long time.
In recent years, they plan to abandon the 6TD engine and develop a new four-stroke engine. They even have a special prototype. However, the size of this engine will increase a lot and cannot be directly stuffed into the T-80.
Go behind the tank.
What's interesting is that their engine also chooses the parameters of cylinder diameter 150 and piston stroke 160, which are exactly the same as the engines developed by the Oriental Power.
Now, although the tank has a prototype, it has no loading target. For the Soviet military R&D system, if there is no qualified loading target, it can only be terminated. They have to continue looking back.
Touch up your own 6TD engine.
Now, of course, I can't talk about the difficulties here. Although I like this son, I cannot ignore the secrets discipline. Besides, my old friends around me are from the KGB, so he must be taboo about these things.
"We are using the 6TD-1 engine now. We are currently developing the 6TD-2 diesel engine. Without changing the volume, the power will be increased to 1,200 horsepower. The performance of this engine will definitely be stronger."
Raba said.
"No, it's useless to change it." Wang Erzhu said: "Its torque is not high, which is determined by congenital factors. I guess its connecting rod is definitely not long enough."
Wang Erzhu doesn't usually speak like this. Why do you always sing against others now? Qin Zhenhua was a little puzzled at this time, but he quickly realized that it was Wang Erzhu who was using this method to vent his dissatisfaction with the other party. After all,
, the other party has not fulfilled his responsibilities as a father.
"Yes, under the same diameter, torque depends on the piston stroke. If the piston stroke is insufficient, it will inevitably lead to insufficient torque. This is its congenital defect." Duraba admitted: "We plan to develop 6TD-after 6TD-2, we plan to develop 6TD--
The 3 engine is expected to increase by about 200 horsepower, but then it is estimated that it can only be solved by increasing the diameter and stroke of the piston, which will increase the torque, but the same will also increase the size of the engine."
After these years, the Molozov Design Bureau suddenly discovered that the most suitable thing for them is to continue to improve this level of opposing engine. It has six cylinders and it is impossible to add one to seven. Therefore, they
It is planned to increase the diameter and stroke of the piston, which will increase the displacement and further increase the power, but in this way, the engine size will be increased again.
In short, that's what happened in the future. Now, the first thing to solve is the maturity of the 6TD-2 engine and the pre-research of the 6TD-3 engine. Then increase the speed slightly, so that you can persist for more than ten years after this.
, As for the situation more than ten years later, who can tell it correctly?
"Is this your old friend?" Qin Zhenhua finally changed the topic. He had seen it. The man just wanted to say hello several times, but Du Laba and Wang Erzhu had not finished talking, and everyone was embarrassed to call him.
After breaking him, now, finally found an opportunity, Qin Zhenhua spoke first.
"Yes, we are good friends, my name is Varisi." The other party stretched out his hand and shook hands at Qin Zhenhua.
The other party spoke Russian, and it was not as convenient for communication as Dulaba, so Nie Qianqian was used as an interpreter.
When translating, he naturally brought some private goods, so Qin Zhenhua understood: "It turned out to be Mr. Warisi. Our investigation today ended here. Now, it's time to find a place to have a drink."
When he said this, Qin Zhenhua felt his heart trembling. He knew that whether the purpose of this trip could be achieved depends on discussion with the other party. Will these people sell everything for the sake of profit?
?
It should be true, otherwise, how could you say you are good friends? Those who do what they do shouldn't have friends.
