"The advantage of wheeled vehicles is that they can use a large number of automotive parts, guaranteed reliability and cheap prices." Qin Zhenhua introduced: "After we have introduced Steyer technology, we have put Steyer's WD615 in Steyer
The engine and the matching gearbox are all taken over, and any power is chosen at will. Moreover, we have already cooperated with Mercedes-Benz. If the troops have higher requirements in the future, we can also use Mercedes-Benz engines or Daoyi.
Take the engine from Z to assemble. In short, we can meet any requirements of the troops."
"If it's appropriate, it should be better to change the Deutz engine." Just as Qin Zhenhua introduced, someone started to study it later.
Why is Doitz good?
Qin Zhenhua knew in his heart that Deutz's engine had been assembled on Hanyang's tractor.
At last year's military parade, Hanyang's tractor was capable of traction vehicles, and naturally there was also the contribution of a machine factory. Hanyang tractor was mainly equipped with a 320-horsepower BF8L413FC type 8-cylinder 4-stroke
Direct injection air-cooled supercharged diesel engine.
This kind of diesel engine is a real military engine because it is air-cooled!
The climates of major eastern countries vary greatly from north to south, especially in the north. When it is cold, the temperature outside can reach minus 20 degrees Celsius. If it is a water-cooled diesel engine, remember to release water. Then, it is best to need hot water before starting.
Preheat the engine.
In this way, in war, operation will be inconvenient.
Air-cooled, it is not so particular. The air intake system has a heating plug that is specially preheated. Before starting, turn on the preheating for a few minutes, and then you can turn the start knob. This excellent engine is only maintained.
In place, even if it is within minus twenty-five degrees Celsius, it can be successfully started at one time.
In the early days, Hanyang trucks directly used purchased diesel engines. After the initial use was satisfactory, the country had decided to introduce the technology of this engine to produce it itself.
Therefore, compared with civilian Steyr engines, the troops prefer air-cooled engines. Moreover, when the troops sometimes need to maneuver long distances in the Gobi and desert terrain, the advantages of air-cooled engines are reflected.
Come out.
After being produced by itself, this engine has a wide range of uses. Many military vehicles, including 63 armored vehicles, have been replaced, and it is also considered a pillar in the army.
"Of course this is fine. We just need to coordinate the engine, and we can replace the engine at any time to test it." Qin Zhenhua said.
He is also very familiar with this engine. The purchase price is more expensive than Steyr's. Since the army has requested this, we will agree.
"Well, this is OK." The man who just raised the engine nodded and agreed.
"The entire body is welded from thin steel plates. Our current standard is built to prevent 7.62mm machine gun bullets, and the same is true for tires."
In later generations, when this infantry fighting vehicle was put into service, there were many oppositions. Many people criticized it as not called an infantry fighting vehicle, and it could not even be defensive to a 12.7mm machine gun bullet. What's the use?
This is just a matter of combat thinking. You cannot have both fish and bear's paws. Does an infantry fighting vehicle pay attention to maneuver or protection?
The Israelites attached the most importance to protection. They even used tanks to transform infantry fighting vehicles, which were often weighing thirty or forty tons. At this level, fuel consumption would also increase a lot.
For the Eastern powers, the army's long-distance maneuvering currently relies on cars, or even on two legs. Therefore, no matter how poor the protection of this wheeled infantry fighting vehicle is, it is better than that of trucks? In the army, it is from motorcycles.
In the process of transformation from mechanization, a large amount of procurement requires high funds, and it is only possible to save a little.
Moreover, on the battlefield, the most threatening is the AK series rifle. This kind of rifle has now spread all over the world, so it is enough to use the protection of this kind of rifle as an indicator.
You don’t have to pursue the highest level, just pursue enough. How can you change the army with a huge army with millions?
Even the Type 63 armored vehicle has such protective power and no pursuit of higher standards.
"It also has water navigation capabilities, with special propellers at the tail for water propulsion. There are waveproof boards in front, which are supported when sailing on water."
Seeing that the leaders of the army looked endless, Xie Huimin was there and finally coughed twice: "Cough, cough, leaders, our self-propelled anti-tank gun has more than 550 mm armor-piercing capabilities."
As soon as this sentence was said, the leaders of the army immediately shifted their interest from the wheeled infantry fighting vehicles.
This data is of great significance.
Five hundred and fifty millimeters! In this era, the protection of tanks has advanced to the order of 500 millimeters. Just like the British Chobam armor, they are confidently proclaiming that their protection power exceeds five hundred
mm.
However, this is still just a claim that in this era, five hundred millimeters are still an almost insurmountable gap, and the biggest enemy of our side, the Soviets, no matter how advanced the tanks and the protection power are, they will never exceed five.
Hundred millimeters.
In other words, we already have a super weapon?
"When did our 120mm cannon have such power?" said Mr. He: "Isn't it five hundred millimeters in previous reports?"
At the beginning, when selecting the cannon, Xie Huimin's confidence came from the depth of the cannon. At that time, it was 500 mm and reported it to everyone present, but in the end he lost to 125 mm, not because of his power.
Not enough, but because it is impossible to install an automatic loader!
They would not be willing to fail. After a period of destruction, they were installed on the chassis at Qin Zhenhua's suggestion and turned into a self-propelled anti-tank gun.
However, at that time, I just said that the gun barrel was stuffed in. Unexpectedly, the Second Machine Factory not only did these things, but also tapped the potential of the 120mm gun again!
Even Qin Zhenhua was a little curious, how did you do it?
Although it has only been lifted for fifty millimeters, it is not easy to do. For example, the German 120 millimeter tank gun is currently using the technology introduced by Israel, using the overall tungsten alloy as the core, and it has been added.
The aspect ratio has reached this order of magnitude, but what about our side? Our metal smelting level is definitely not as good as an old industrial powerhouse like Germany. Of course, our side's diameter is larger, and the 50-fold diameter must be greater than that of our side.
With a 44-fold diameter, it only takes a little more weight to reach a depth of 500 mm, which is already the strongest.
How could it be that performance is improved by 10%?
