Before the Soviet Union collapsed, the Soviet Union had been firmly following its own path. Therefore, the weapons in the world were divided into two systems, one was Western and the other was Soviet. The Soviet Union system had many characteristics
For example, it does not pay attention to ergonomic engineering and requires people to adapt to machines. Take fighters as an example. The cockpit remains unchanged and is always the same. In this way, if a pilot wants to change to a new aircraft, it will be
There is no need for training, and when you sit in, you always feel familiar.
The Western ones are different. For the F-16, there is a big difference between the early cockpit and the later cockpit. Therefore, even if it is an aircraft of the same model, the pilot must be trained again before he can become proficient.
Soviet tanks have always paid attention to their low appearance, which can reduce the probability of being hit by the enemy's tanks. As for the small internal space of the tank, they are not what they have to consider. At worst, just find some short guys from Central Asia to drive.
Moreover, this is beneficial. Even if the tank is captured by Western Europe, the tall Europeans will not be able to start the Soviet tanks.
At the same time, in order to pass through various bridges, the Soviet tanks also strictly limited their weight. In the Soviet era, the weight of the tanks could not exceed forty-five tons (there were also breakthroughs, but the heaviest would not exceed five.
Ten tons, compared with the sixty or seventy tons of tanks in the West, there is still a big gap.) This weight limit caused the Soviet tank designers to rack their brains to reduce the tank design. T-
This is how the 64's weird two-stroke diesel engine comes from, and it's best to be mature.
Because of its small weight, tanks in the Soviet era did not require a diesel engine with a large horsepower. For the T-72 tank, if it has a 780-horsepower diesel engine, it can run whizzingly. If it is upgraded to 900-horsepower, it will be a swaying machine.
, that will definitely run at a speed that is against the will of heaven.
However, after the collapse of the Soviet Union, the Soviet military-industry system also collapsed. Many military-industry was gradually following the West. Take tanks as an example. The weight of the big-haired tanks began to grow larger and larger.
, they have to develop larger engines. In fact, this is almost a vicious cycle. When the tank's protection is enhanced, the tank's volume will become larger. Then, the tank's self-weight will become larger, so it will be used even larger.
The powered engine, in fact, the maneuverability of the tank has not improved. The T-72 tank, with a 780-horsepower engine, drives a 41-ton tank. The Challenger, with a 1,200-horsepower power, drives a more than 60-ton tank, so,
The increase in power is completely consumed by the increased weight.
For a long time, Soviet tank engines used B-2 engines to continuously tap potential and improve their power performance. After the collapse of the Soviet Union, Kharkov became a 2-mao man. The gas turbine was too fuel-intensive, so
Damao could only study it on the B-2 engine wholeheartedly.
The original T-34 tank used this engine. When it came to the T-72, it used a supercharger and increased to 780 horsepower. After the collapse of the Soviet Union, they used a turbocharger and passed other
The improvements increased the engine's power to 920 horsepower. After all, after various improvements, the engine's power struggled to increase to 1,200 horsepower. However, the potential of this kind of engine has completely come to an end.
"I remember, when you visited the Soviet Union, you proposed the design ideas for the X-shaped engine for them." Speaking of Damao's tank engine, Nie Qianqian was also excited and continued to introduce to Qin Zhenhua: "In Damao,
Most engine factories are still content with the status quo, but some engine factories have already taken action. Among them, Ural's engine factories have begun to design new X-type engines. We will introduce this engine to the point of
We will still support this engine.”
There is no grudge against Da Mao. Originally, Nie Qianqian wanted to attack Ermao's tank engine, so that Ermao's engine would steal his own business. As for Da Mao, it was just to save it from being too obvious. So, here
In the article, I will definitely express support.
After hearing Nie Qianqian say this, Qin Zhenhua nodded: "I really didn't expect that they actually wanted to build an X-shaped engine. It seems that in the field of engine development, the route that the Russians took is the weirdest."
Other tank engines are almost all normal V-shaped 12-cylinder structures. Look at the old men, the horizontally opposite two-stroke engine is a weird one. Then, there is a more weird X-shaped engine, which is the only one.
ah.
When I visited the Soviet Union, I saw the Soviets' concerns about the improvement of engine power performance. Qin Zhenhua proposed that they would pair the two B-2 engines and change from V-shaped to X-shaped structure.
Unexpectedly, the other party would really do this.
After all, the technology is the least difficult to do. It maximizes the use of existing technology and upgrades, which not only improves power, but also deceives people and sells tanks better. This is the idea that Damao must have been
.
Nie Qianqian introduced this engine: "This kind of engine can be regarded as a V-shaped 120-degree engine with two six-cylinders, upper and lower cylinders. The upper and lower layers are superimposed and become an X-shaped 12-cylinder engine. From the total number
, 12 cylinders, and even the diameter of the piston is 150 mm, but the stroke is increased to 180 mm, thus increasing the displacement, thereby achieving a power output of 1,500 horsepower. At the same time, the cylinder
The distance between the bodies has become larger, so the problem of too small cylinder center distance on the previous B-2 engine has been completely alleviated."
At the beginning, Qin Zhenhua was unintentionally putting up a random idea, and even made more fools. Unexpectedly, the other party really did what he did. At this time, he thought that the other party actually made such a model.
Qin Zhenhua grinned and began to giggle there.
"Director Qin, what are you laughing at?" Nie Qianqian asked Qin Zhenhua strangely.
Qin Zhenhua then realized that he couldn't help but smile, so he quickly put it aside. After all, this kind of thing was a bit unkind. If he acted too proudly, he would seem unkind. However, Qin Zhenhua still
I couldn't help but laughed again.
While laughing, he said, "I ate tofu brain this morning and found that the tofu brain was actually sweet and there was sugar in it. Is it funny if you say this?"
