Chapter 935 The third generation of tanks did not catch up
The morning time passed, and the representatives of other factories had almost no chance to speak, but only occasionally raised some sporadic questions. At the same time, after this morning's meeting, it was almost certain that the Yimai Factory
The superiors are obviously interested in the three tanks proposed. If nothing unexpected happens, the three chariot arrays in the first three will be fixed like this.
At noon, everyone entered the cafeteria together. Even though they were dining, the topic they discussed was still on equipment.
"Mr. Zhu, you must be very busy during this period." Qin Zhenhua sat next to Mr. Zhu, and while eating, he communicated with Mr. Zhu.
"Yes." Zhu Lao said: "We are watching your second-generation tank project progress smoothly, and our third-generation tanks naturally have to work hard. However, no matter what, it is impossible to catch up with this military parade, which is a pity.
”
If the development of our third-generation tanks is successful, there is no doubt that the third-generation tanks will definitely take the lead. But now, it’s a pity that the progress will definitely not be able to keep up.
I can only look at Qin Zhenhua and the others' performance.
"Yes, our first-machine factory is also looking forward to giving us the third generation of tanks to make them quickly." Qin Zhenhua said.
On this, the first machine factory does not have much resistance. Although it is designed by tank design, the final production and manufacturing will definitely be carried out in the first machine factory. Looking across the country, only the first machine factory can bear this
A glorious and arduous task is coming.
"You can't urge this, either." Zhu Lao said: "We are still anxious. By the way, how is the research and development progress of your factory's 1,200-horsepower diesel engine?"
The third generation of tanks also contributed by the first aircraft factory. In addition to production, they are tank engines.
Since it is going to become a third-generation tank, its weight will definitely be further improved. After all, various parameters have been determined during the design, and this will be a 50-ton tank.
The engine of this level of tank requires at least 1,200 horsepower. In fact, an engine with 1,500 horsepower is the best.
After hearing Mr. Zhu's question, Qin Zhenhua became serious: "Our engine branch has been doing research. If we want to achieve a greater horsepower increase, we need a more efficient turbocharger and higher efficiency.
fuel injection system.”
Since we are planning to increase the power of the engine, we must do various pre-research work. With the maturity of the solution of large cylinder center distance, the problem of heat dissipation of tanks after power increases is no longer a problem, but in other aspects
, it still requires our own unremitting study.
Simply put, to increase the power, you need to bulge more air, inject more fuel, and bulge more air. The engine supercharger is the engine supercharger. The performance improvement of this supercharger has reached a limit, so what is not used.
If processing technology can be improved, new design ideas must be included.
On the other hand, it is the injection system. The higher the fuel injection pressure, the more fuel can be injected and the atomization will be better. A high-pressure fuel pump is not that easy.
"So, do you have a plan?" Zhu asked. If you don't have the right idea yet, once you are dragged down by the engine, it may cause the entire third-generation tank project to be discontinued.
After all, the engine is the heart. Without an advanced engine, everything will definitely be useless.
"We are trying, but if we want to continue to tap into the potential, we believe that the application of high-voltage common rail systems is a route, and now we are carrying out pre-research for corresponding work."
"Common-rail system?" Mr. Zhu immediately frowned: "Are you sure?"
The technology of diesel engines has been developed to this day, and ordinary plunger pumps have been used to pressurize the diesel, and then enter the fuel injector through separate high-pressure oil pipes.
This disadvantage is that when the oil pump is moving, the pressure of the diesel actually changes with the engine running, which leads to the imperfect operation of some cylinders.
Moreover, the faster the engine speed, the greater the pressure of the oil pump, so for old diesel engines, the bigger the throttle, the stronger it is.
The common rail technology can solve this problem. The common rail stores the high-pressure fuel output from the high-pressure oil pump in a pipe close to the fuel injector, and then, which fuel injector is required, it will provide it with which fuel injector.
In this way, the generation and injection process of fuel injection pressure are completely separated from each other. The oil pressure in the common rail pipe is used to ensure that each injector has the same fuel injection pressure. The injection pressure at this time is not affected by the engine speed, thereby ensuring the stability of the engine.
, efficient operation.
In fact, some people have proposed this technology a few years ago, and many companies are doing it, but so far, no qualified products have been released. After all, its fuel switch has become a computer to control, and it will
There are many technical difficulties waiting to be overcome.
However, if this problem is solved, it is conceivable that our engine will definitely be more advanced.
"It's hard to say, we can only do 100% of our efforts." Qin Zhenhua said: "At present, we rack our brains. Maybe it's okay to increase it to 1,200 horsepower, but to achieve a performance improvement of 1,500 horsepower, then
I guess this technology can only be used.”
After talking about the engine problem, Qin Zhenhua continued: "In fact, compared to the engine, the transmission system is more difficult. We do not have a transmission of this level yet, so I suggest that we can introduce it from abroad, such as Zee Germany.
The LSG3000 transmission system of Fu Company is good. Let’s introduce it here, then figure it out yourself and then copy it.”
Advanced tanks must have advanced transmission systems. If you want to use the previous fixed shaft or even the planetary gearbox method, it is too backward. Use a high-level hydraulic transmission system to realize the steering wheel operation.
It's really comfortable.
The tank projects exported by the first machine factory have begun to adopt this method, but they are matched with weak power engines. The stronger the power, the stronger the transmission system required.
My own research may last for a long time. After all, our best in China is surveying and mapping.
"Yes, we are also considering it. By the way, Zhenhua, you have a good relationship with the Germans. Should you leave this matter to you?" Zhu Lao asked.
Qin Zhenhua quickly shook his head: "Forget it, this is the business of your tank design institute. Don't want me to get involved, I'm not available."
As he said that, Qin Zhenhua looked over there. Liu Tiande was talking to several leaders, not knowing what he was talking about.
