Chapter 1983

Qin Guan felt his eyelids jump.

Qin Guan is not worried about gas turbines. Although gas turbines have many advantages, only one disadvantage is enough, that is, fuel consumption. Therefore, Boris takes the initiative to let his own side test. In fact, there is no need to worry. After all, few countries can afford the fuel consumption of such gas turbines.

However, this 6TD engine is different. This is the standard configuration of Khalid tanks in the history of parallel time and space.

For tanks, the smaller the size of the engine, the greater the power, the better the effect. Look at Western tanks, the front and rear heights are different, and the rear is more than ten centimeters higher, because the engine in the rear engine compartment is too large to be high enough.

In this way, when the tank turret turns back, the downward shooting angle is not as high as that in front.

This is also useful. In a tank battle, if you are pursued by the enemy, you can only turn the turret backward to hit the other party. However, your armor piercing projectile has limited performance and can't tear off the other party's main armor, you have to hit the other party's track. If the downward angle of the gun barrel is limited, you can't reach it.

The tanks of Xiong state are flat in front and back, because the tank engine of Xiong state is very small, which is also caused by the different ideas of both sides.

Look at the 1500 horsepower engine used in the Han Dynasty. The V12 engine is used to increase the power completely through the most conventional way. The displacement is increased to 47 liters, and the speed is increased to 2600 rpm, so as to obtain such power. The quality is stable and reliable, the service life is long, the fuel consumption rate is low, and there is almost no failure. However, the volume is huge.

In contrast, Xiong Guo prefers tank engines with small volume and high power density, so they are interested in two-stroke engines.

The engine has four strokes. The intake air is compressed to do work and exhaust. An ordinary engine is completed in two revolutions, and the piston moves back and forth twice.

The two-stroke engine compresses the four strokes into one circle. The piston reciprocating once is completed, and the work is done once when it rotates once. Therefore, under the same displacement, the two-stroke engine theoretically has the potential of twice the power of the four stroke engine.

Of course, there will be a certain loss in practice, which can only reach about 1.7 times, which also means that under the same volume, the power will be 1.7 times that of four strokes, which is very suitable for tanks.

In this case, they developed 5td engine. This is a unique horizontally opposed 5-cylinder engine. Compared with the 12 cylinders of the V-12 engine, it has only 5 but 10 pistons. Because the pistons move towards both sides, it forms a strange way. The whole displacement is only 13.5 liters, the maximum speed is 3000 rpm, and the power reaches 426 kW, After that, through the strengthening of the engine block and the optimization of the composite supercharging device, the power of 5tdf engine was increased to 515kw and the speed was reduced to 2800 rpm, becoming the power system of t-64.

5td, that is, five cylinders, has such great power. Later, in order to provide the engine for the T-80, another cylinder was added to it to become 6TD.

Although the T-80 uses a gas turbine, which has been equipped and served in the army for many years, the feedback from the army shows that the fuel consumption of gas turbine is quite high, so there is still a demand for diesel engine.

They improved the engine. In addition to adding a cylinder, they also improved the supercharging device. The power of the final 6td-2 engine reached 883 kW, and the engine speed was reduced to 2600 rpm. The power was sufficient, the volume was very good, and the reliability was improved.

Therefore, after repeated comparison, the holy state finally chose this engine and assembled it on their Khalid tanks. Later, due to war, the holy state urgently purchased a batch of T-80 tanks. A big reason is the inheritance of this engine. The same engine helps to reduce logistics support.

Now, the Han state is developing new tanks for the holy state, but there is really no suitable engine.

Han's own engine has good power and 1500 horsepower, which is the strongest. However, at the same time, it is also very large and expensive. Reduce the proportion and change it to 1200 horsepower? Or use your previous engine to improve power?

None of this is realistic.

Now, when the news about the development of tanks for the holy nation came out, Boris actually brought this engine. So, did the holy Congress choose this engine?

While Qin Guan was thinking about these problems, a forklift had come. Although it was an engine, in fact, it was an integral power unit. In addition to the engine, there was also a transmission.

"I think it can be installed on our No. 3 sample car for test. The size of this engine looks very small."

Our own 79 tank is stuffed with a 1500 horsepower engine. The volume of the engine compartment is much larger than that of the T-80. Now if this tank is stuffed, it will certainly face the problem of mismatch. This is not the problem of adding more water and more water.

Sample car 3? After hearing Zhu Lao's words, Qin Guan was stunned again. When he came to plant 6617 in grassland city this time, he saw all new things. What is this sample car No. 3?

"Mr. Qin, at that time, you gave us the design drawings, and our factory produced a sample car according to the design drawings. Now, the car body should be built, and it is difficult to install parts in it. Now it seems that the two power units are almost the same size, just like they are designed for you." Mr. Zhu whispered to Qin Guan.

Qin Guan suddenly understood.

I mentioned the Khalid tank project at that time. When I was excited, I readily exchanged the information and brought it to plant 6617. Originally, I wanted them to be prepared. When the holy people came, I could introduce it to them. However, the people here were more anxious. When they got the information, they actually started construction, and the car body had been worked out!

They really have a lot of money! With the continuous export of military industry to foreign countries, these domestic military factories are very rich, and the small coffers are rich in funds.

"Please our guests to stay in the guest house first," Qin Guan said.

When Zhu Lao just spoke, he was very quiet. After all, Boris is an outsider. Boris can't know the inside story of this research and development.

Boris came from a long way and stayed here for a few days. After all, he came uninvited. It's better for his own side to discuss. You can also practice when you get on the bus.
