"Our factory has focused on the research and development of tanks. Now, various problems of our third generation tanks are continuing to be solved, and the Khalid tank project of Lao Ba is also developing. We cannot just focus on
In the current situation, there should be enough pre-research. I think there should be new projects in our factory." Qin Zhenhua gathered the staff of the First Machine Factory together and started a meeting.
Although we are in the testing ground now, all the backbone of the First Machine Factory has arrived, so a meeting is held here on site, which is also a key meeting of the First Machine Factory.
"Director Qin, what new project are we going to do?" After hearing Qin Zhenhua's words, everyone present began to flash. For a company, it is necessary to continue to carry out research and development, so that there will be progress and a certain amount of
Only by pre-research can we take a safe path.
Now that Qin Zhenhua said he wanted to do a new project, everyone naturally understood that this was a must, but he didn't know what to do.
"The second generation of medium-sized artillery universal chassis." Qin Zhenhua said.
The second-generation medium-sized artillery universal chassis? When everyone heard this, they were stunned: "Don't we have a 321 medium-sized chassis?"
In fact, the 321 medium-sized chassis was not created by the first machine factory, but was made by other brother units. However, there were a lot of technical problems and they were never mature. Later, in order to be able to successfully launch the 155mm howitzer, the first machine factory successfully launched the 155mm howitzer.
I personally launched the horse, improved the chassis, and finally matured. I sold it with a 155mm howitzer.
The 321 medium-sized chassis has become a trump card in a machine factory. At the same time, it has obtained a lot of applications. Many equipment have chosen this chassis. In theory, this has only been happening for more than ten years and has not yet been developed.
What about the second generation of medium-sized chassis.
"Yes, there is indeed such a chassis, but it is already out of date." Qin Zhenhua said: "When we were doing it, we just drove the ducks to put it on the shelves and solved the problem of whether there is or not. Now it seems that a lot of technical data is
If it is not prominent, for example, it cannot accompany our main battle tanks."
The third-generation tank is about to be in service. Compared with previous tanks, its various indicators have been improved by a level. For example, its maximum speed can reach 70 kilometers per hour, and it can run 50 kilometers off-road.
Every hour, while the tanks used to run fifty kilometers per hour, and when they crossed the road, they were thirty or forty kilometers per hour. This means that the equipment in the past could not keep up, needless to say,
With the tank troops and equipment that undertakes air defense cover capabilities, we must also keep up.
This is of course an inspiration from the Doyle M1. Although the Doyle M1 uses seven load-bearing wheels, in fact, this code-named GM-5955 chassis is actually improved from the Soviet GM-569 medium chassis
The others who came here, except for the different number of load-bearing wheels, were almost the same. This chassis was a general chassis in the Soviet era. This series of vehicles were used in "Doy M1", "Tunguska", "beech",
The air defense systems such as ZSU-23-4 are very famous.
The Russians can develop such a general chassis, and the first-machine factory can do it. Compared with the past generation of chassis, this second-generation medium-sized general chassis must first increase the power of the engine, and look at the Doyle M1.
It uses a 12-cylinder engine with power of 710 horsepower and 840 horsepower.
The Eastern powers also need it. If you want to have an advanced chassis, then the power cannot be lost. Only when the power is enough, vehicles with this chassis can keep up with the pace of the third-generation tanks and provide air defense cover.
"In order to be able to advance with the main battle tank, I think that the engine of this medium-sized chassis must reach at least 800 horsepower." Qin Zhenhua continued.
Eight hundred horsepower! Everyone took a breath of air conditioning. Director Qin, your tone is really big.
The engine of the 59 tank, the main force of the Eastern power, is only 500 horsepower. When it reaches 80 tanks, it has only been increased to 730 horsepower. Now, it still takes 800 horsepower to build a medium-sized general chassis?
Where does the engine come from?
Everyone has this question.
"At present, our main battle tank has an engine of 1,200 horsepower. At the same time, when designing, we are working on modularization. There are 1,200 horsepower and eight cylinders.
It's 800 horsepower, so it's okay for our second-generation medium-sized universal chassis to use a new eight-cylinder engine to achieve a power output of 800 horsepower."
"No problem, and all kinds of faults have been eliminated on the tank. There will be few faults in this 800 horsepower engine, so we are confident." Wu Ruihua spoke.
"As for the transmission system, we need to develop an integrated transmission system." Qin Zhenhua said: "This is to give our next generation tank hydraulic transmission system a low-power test version."
Every generation must be innovative. With the engine, the transmission system cannot be left behind. After all, Qin Zhenhua knows that the double-sided transmission used by the third-generation tanks is just a helpless choice. In the future, you must use a high-end hydraulic transmission system.
, so, it is better to test it on this second-generation medium-sized universal chassis.
"Well, the difficulty is quite high, but since it is a difficult situation that we always have to face, it is OK to start from now on. We have accumulated experience in this and hydraulic transmission of future tanks
The improvement of the system is also very helpful,” said another engineer.
Hydraulic transmission system is the future and must be overcome. Therefore, it should be appropriate to build a hydraulic transmission system with an 800 horsepower engine to reduce the difficulty.
"Also, regarding its suspension system, we need to consider using liquid suspension." Qin Zhenhua continued.
Sure enough, the second-generation medium-sized universal chassis that Qin Zhenhua is going to build is very different from the first-generation chassis, and the entire chassis has been upgraded.
Liquid air suspension is also high-end. I did it on the 122 tank, but the technology failed and a lot of problems arose. Now, decades have passed, and the processing technology and material level of the Eastern powers have very good
A big improvement, so you can also try it.
"For our artillery, there is a lot of recoil when shooting, and the torsion rod suspension will buffer, so that the vibration of the vehicle body will have a great impact on the shooting accuracy. If liquid suspension is used, it can be locked
Stop the stroke, which will improve the shooting accuracy." Qin Zhenhua explained: "Even if we only use liquid air suspension in a few groups, it will be of great benefit."
