The first thousand three hundred and fifty-three chapters visit the engine factory
At the beginning, the first machine factory was built from scratch on the grassland, so it was built directly with the drawings of the Soviet tank factory. So, it is not surprising to find a familiar feeling now.
"This is our engine manufacturer." Kartsev led everyone along the factory road. The first thing he walked into was not the assembly workshop, but the engine manufacturer.
It has always been said that the T-72 tank pursues reliability and uses existing production lines as much as possible to produce in large quantities, which can be seen from the tank engine.
Back then, in order to build the T-64 tank, the Soviets took a lot of effort on tank engines. What the tank engine needed was small size and strong power, especially the Soviet tanks, which were originally small.
In order to enable the T-64 tank to obtain qualified power, the Morozov Design Bureau decided to use a two-stroke diesel engine, and it is a unique horizontal opposing structure in the tank industry, which can be said to be the only one.
In order to match the T-64 tank, the engine was developed at the Mareshev factory in Kharkov, and the project even formed a new project headed by Professor Alexey Dmitryevich Caromsk.
The design bureau specially designed 5TD engines and even built a new large workshop for the production of power plants.
It can be said that the investment in this area is quite large, but in the early stage of the 430 engineering prototype, the reliability of these power systems is quite poor.
Instead of following the other party's old path, Kartsev abandoned this impractical power system, but continued to develop on the B-2 series tank engines.
That's right, this is the 12150 series diesel engine of the Eastern Power. It was originally used on the T-34 tank and has been improved bit by bit and has been used until now.
"What you see is our tank engine production line. I guess you will feel very familiar, and it is exactly the same as the production line of the Eastern Power." Kartsev led everyone into the factory and explained to the production line.
: "I wonder if your domestic B-54 engine is still in production now?"
For the Eastern powers, the B-54 engine is a 12150L diesel engine? It is used on the 59 tank. It has only 382 kilowatts of power, which is only barely enough.
The Eastern powers improved this diesel engine by about 10% of its power, and used it in the 69 tank, while the Soviet Union also improved this diesel engine.
"We are still producing this diesel engine." Qin Zhenhua nodded.
There are a large number of 59 tanks in China? These tanks still need to have enough engines to use. Of course, the 59 tanks are no longer the original engine, but the version that has been improved and has increased its lifespan? However, here
No need to mention it, but listen more and watch more. Are you here to learn from the scriptures? It is not here to introduce your own tank.
"The foundation of this engine is quite good? On the basis of this diesel engine, we strengthened oil supply, improved combustion, and strengthened the structure to create a 427-kilowatt B-55 engine." Kartsev said:
However, this improvement is limited after all, and it also reduces the lifespan. So we started to develop a supercharged diesel engine, and first made the engine. At that time, the supercharger was too large, so we improved the supercharger device.
Strengthen the structure and create the current 574-kilowatt B-46 engine."
At this time, after walking through the engine casting workshop, the engine body inside was pouring, and steel splashed, and Kartsev's splashing stars were also splashing. Although he was not young, his body was quite tough.
When the old man was in his 90s, he still had steady steps.
"Compared with the previous B-54 engine, the structure is basically the same. The production workshop does not need to move, and can produce a new engine. We just canceled the eighth main bearing of the original engine crankshaft to make the engine length.
It is basically the same as the B-54 engine. It can be said that if we need it, we can also stuff this engine into the T-55 tank."
When he talked about this, he was still very proud. Compared with the original B-54 engine, the power has increased by 50%!
When the overall parameters of a certain model of engine are determined, if you want to further increase its power, you have to "inject more fuel", "inject more air intake" and "accelerate the circulation rate". "inject more fuel" is limited by the engine cylinder
The combustion efficiency of the combustion efficiency. If there is not enough air inside, the combustion will be incomplete if there is too much fuel injection. It is closely related to "more intake". In order to intake more, the pressure must be supercharged; "accelerating the circulation rate" means increasing the engine
However, this will cause the working conditions of a series of components such as pistons and crankshafts to deteriorate, thus affecting the reliability of the entire machine. Except for the Germans who dared to increase the engine to 2,800 revolutions with their industrial foundation, any country
Don't dare to follow suit.
In fact, after using mechanical supercharge, the B-46 engine reduced the speed to 2,000 rpm, further improving reliability.
Kartsev was quite satisfied with this improvement.
"Mr., please ask," Qin Zhenhua asked his own question in a timely manner: "As the tank continues to be modified, the weight will become larger and larger, and the power will appear to be less and less than enough. So, has your development B-
The next generation of 46 engines? Is there any engine with more power than it? After all, there must be more power in the Mareshev factory, right? Maybe it has reached one thousand horsepower."
Many of the military-industrial enterprises in the Soviet Union are highly confidential. Nie Qianqian can get so much information thanks to her working in the media industry before, she met many friends and collected them everywhere. If you want to say confidential words, you won’t be able to do it.
knew.
But I don't know, it's okay to be fooled. The 5TD tank engine of the Mareshev factory is definitely not the end. Seeing that the T-80 tank used a gas turbine and snatched their limelight, will they not recover it again?
?
Hearing Qin Zhenhua's words, Kartsev frowned. Yes, there is indeed a diesel engine with a diameter of 1,000 horsepower at the Mareshev factory. The engine code-named 6TD was replaced with the T-64, but
,How did the other party know?
"How did you know this little comrade?" Kartsev asked with a frown. Could it be that the secret leaked from the Mareshev factory?
"I guess." Qin Zhenhua said: "Even our Eastern powers have begun to steadily put into production of diesel engines with one thousand horsepower. The Soviet Union is a tank power, so how can it not have a diesel engine with one thousand horsepower?"
Guessing? Kaltsev felt chills. In the inspection team of the Eastern Powers, Qin Zhenhua was relatively young, so Kaltsev didn't care. But now, he found that when Qin Zhenhua was talking, everyone around him was there
Pay attention, does this young man have any identity?
"How did you guess this little comrade? Where do you work?" Kartsev asked.
"One Machine Factory, my name is Qin Zhenhua." Qin Zhenhua said, "I am always embarrassed to say that I am the factory director, right?"
"Qin Zhenhua?" Kartsev raised his eyebrows and suddenly thought of something: "Are you the famous Director Qin of the First Machine Factory? The Director Qin who developed the 85 tank?"
