Chapter 1983: Small size, high power

Qin Guan felt his eyelids jump a little.
Qin Guan is not worried about gas turbines. Although gas turbines have many advantages, only one disadvantage is enough, which is fuel consumption. Therefore, now that Boris takes the initiative to let him test, there is no need to worry about the fuel consumption of this gas turbine. , Few countries can afford it.
However, this 6TD engine is different. This is the standard configuration of the Khalid tank in the history of parallel time and space.
For tanks, the smaller the size of the engine and 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 of the engine volume in the engine compartment behind. Too big, not high enough to use.
In this way, when the tank turret turns backwards, the downward shooting angle is not as high as the front.
This is also useful. In a tank battle, when you are chased by the enemy, you can only turn the turret backward to hit the opponent. However, your own armor-piercing elasticity is limited and you cannot tear the opponent's main armor. If the downward angle of the barrel is limited, it will be out of reach.
The bear country’s tanks are the same front and back, because the bear country’s tank engines are very small, which is also caused by the different thinking of the two sides.
Take a look at the 1500 horsepower engine currently used by Han Guo. The V12 engine is used. The power is increased in the most conventional way. The displacement is increased to 47 liters, and the speed is increased to 2600 rpm. The power, the quality is stable and reliable, the life is long, the fuel consumption is low, and there is almost no failure, but the volume is huge.
In contrast, Xiong Guo prefers tank engines with small volume and high power density, so they are attracted to two-stroke engines.
The engine has four strokes, the intake is compressed and the exhaust is performed. The ordinary engine is completed in two revolutions, and the piston reciprocates twice.
The two-stroke engine compresses these four strokes into one revolution. The piston reciprocates once and completes the work once. Therefore, under the same displacement, the two-stroke engine theoretically has four Double the power potential of a stroke engine.
Of course, there will be a certain amount of loss in practice, which can only reach about 1.7 times. This also means that under the same volume, the power will be 1.7 times that of the four-stroke, which is very suitable for tanks.
In this case, they developed a 5TD engine. This is a rather 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 to both sides, the composition is strange. The entire displacement is only 13.5 liters, and the maximum speed is 3000 rpm, which reaches 426 kilowatts of power. After that, through the strengthening of the body and the optimization of the compound supercharging device, the power of the 5TDF engine has been increased to 515 kilowatts. It was reduced to 2800 revolutions per minute and became the power system of the T-64.
5TD means 5 cylinders, which has such a large power. Later, in order to provide the engine for the T-80, another cylinder was added to it, which became a 6TD.
Although the T-80 uses a gas turbine, it has been equipped with the army for many years, but from the feedback of the army, the fuel consumption of the gas turbine is quite high, so there is still a demand for diesel engines.
They improved this engine. In addition to adding a cylinder, they also improved the supercharging device. The final 6TD-2 engine's power reached 883 kilowatts, and the engine speed was reduced to 2600 rpm, which was enough power. The size is very good, and the reliability is improved.
Therefore, after repeated comparisons, the Holy Nation finally chose this engine and assembled it on their Khalid tanks. Later, due to the war, the Holy Nation urgently purchased a batch of T-80 tanks, one of which was a large one. The reason is the inheritance of this engine. The same engine helps reduce logistics support.
Right now, Han is developing new tanks for the holy nation, but there is really no suitable engine in terms of engines.
Han Guo's own engine has good power, 1500 horsepower, which is the most powerful, but at the same time, it is also very large, expensive to build, and reduced to 1200 horsepower? Or use your previous engine to increase power?
None of this is realistic.
And now, after the news of the development of a tank for the Holy Nation spread, Boris actually brought this kind of engine. Then, did the Holy Congress choose this kind of engine?
While Qin Guan was thinking about these issues, a forklift had already arrived. Although it was an engine, it was actually an integral power unit, in addition to the engine and the transmission.
"I think it can be tested on our No. 3 prototype. The size of this engine looks very small."
The 79 tank of our own is packed 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 packed in, it will definitely face the problem of incompatibility. This is not a question of adding more water to the noodles and adding water to the noodles.
Prototype 3? After hearing what Zhu Lao said, Qin Guan was stunned again. This time he came to the 6617 factory in Prairie City and saw all new things. What is this No. 3 prototype?
"Mr. Qin, you gave us the design drawings at that time, and our factory produced a prototype car according to the design drawings. Now, the car body should have been built, and it’s just a matter of installing parts inside. These two power units are about the same size, as if they were designed specifically for you." Zhu Lao said to Qin Guan in a low voice.
Qin Guan understood it all at once.
I mentioned the Khalid tank project at the time. When I was excited, I exchanged the information and brought it to the 6617 factory. It was originally for them to have a preparation. When the holy nation came, I could introduce it to them. But, the people here are even more anxious. After they got the information, they actually started construction, and the car body has been built!
They really have a lot of money! With the continuous export of military industry to foreign countries, these domestic military factories are very wealthy, and small coffers are abundant in funds.
"Our guests, please stay in the guest house first." Qin Guan said.
When Zhu Lao talked, it was very soft. After all, Boris is an outsider, and the inside story of this kind of research and development cannot be let Boris know.
Boris came from a long distance and stayed here for a few days. After all, he came uninvited. It's a good idea to discuss it with him. You can also practice and see when you get in the car.
