"The advantage of wheeled vehicles is that they can use a large number of auto parts, the reliability is guaranteed, and the price is cheap." Qin Zhenhua introduced: "After we have introduced Steyr technology, we will take Steyr's WD615 engine and supporting gearbox, any power can be chosen at will, and we have a cooperation intention with Mercedes-Benz, if the army has higher requirements in the future, we can also take the Mercedes-Benz engine, or Deutz engine, to assemble, in short, no matter what requirements the army has, we can meet." ”

"If it's appropriate, it would be better to switch to the Deutz engine." Just when Qin Zhenhua introduced, someone began to study it later.

Why is Deutz good?

Qin Zhenhua knew it in his heart, because Deutz's engine had been assembled on Hanyang's tractor.

At last year's military parade, the towing of the Dongfeng-5 missile was only capable of Hanyang's tractor, which naturally also had the credit of a machine factory, and the Hanyang tractor was mainly equipped with a 320-horsepower BF8L413FC-type 8-cylinder 4-stroke direct-injection air-cooled supercharged diesel engine.

This diesel engine belongs to a real military engine, because it is air-cooled!

The climate of the eastern countries is very different from the north and the south, especially in the north, when it is cold, the outside temperature can reach minus 20 degrees, if it is a water-cooled diesel engine, then you have to remember to release water, and then before starting, it is best to need hot water to warm up the engine.

In this way, in the war, it is inconvenient to operate.

Air-cooled, it is not so particular, the air intake system has a special preheating plug, before starting, open for a few minutes to preheat, and then, you can twist the start knob, this excellent engine, as long as the maintenance is in place, even if it is minus 25 degrees Celsius, it can be started successfully at one time.

In the early days, Hanyang trucks directly used purchased diesel engines, and after the initial use was satisfied, the country has decided to introduce the technology of this engine to produce it itself.

Therefore, compared to the civilian Steyr engine, the troops are more inclined to use air-cooled engines. Moreover, when the troops sometimes need to maneuver long distances in the Gobi and desert terrains, the advantages of air-cooled engines are also reflected.

After the self-production of this engine, it has a wide range of uses, and many military vehicles, including 63 armored vehicles, have been refitted, and they can be regarded as pillars in the army.

"Of course, this is no problem, but we need to coordinate the engine, and we can replace the engine at any time to test." Qin Zhenhua said.

He is also very familiar with this engine, and in terms of purchase price, it is more expensive than Steyr's, and since the army has asked for it, we will agree.

"Well, that's fine." The man who had just proposed the engine nodded in agreement.

"The entire body, welded from thin steel sheets, is built to our current standards to protect against 7.62mm machine gun bullets, as well as the tires."

In later generations, when this infantry fighting vehicle was put into service, there were a lot of objections, many people sprayed it not as an infantry fighting vehicle, and even a 12.7 mm machine gun bullet could not be prevented, what was the use?

This is just a matter of operational thinking, you can't have both, an infantry fighting vehicle, does it pay attention to mobility, or pay attention to protection?

The Israelis pay the most attention to protection, and they even use tanks to transform infantry fighting vehicles, which can easily be thirty or forty tons of full weight, and at this level, fuel consumption will also increase a lot.

For the big countries in the East, the long-distance mobility of the army still relies on cars, or even two-legged, so this kind of wheeled infantry fighting vehicle, no matter how bad the protection is, is better than a truck, right? In the process of the army's transformation from motorization to mechanization, a large number of purchases require a high amount of money, and it is a point that can be saved.

Moreover, on the battlefield, the greatest threat is the AK series rifle, which has now spread all over the world, so it is enough to use the protection of this rifle as an indicator.

There is no need to pursue the highest, just pursue enough, how can it be possible to redress millions of army troops?

Even the Type 63 armored car has such a protective force, and there is no pursuit of higher.

"It also has the ability to sail on the water, with a special propeller at the tail for propulsion on the water. There is a wave guard in front and is propped up when sailing on the water. ”

Seeing that the leaders of the army looked endless, Xie Huimin was there, and finally coughed twice: "Ahem, ahem, leaders, our self-propelled anti-tank gun, the armor-piercing ability has exceeded five hundred and fifty millimeters." ”

As soon as these words came out, all of a sudden, the leaders of the army immediately shifted their interest from 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 Chobham armor of the British, who confidently proclaimed that their protection exceeded 500 millimeters.

However, this is still just a claim, in this era, 500 mm is still an almost insurmountable gap, and their worst enemy, the Soviets, no matter how advanced the tank, will never exceed 500 mm.

In other words, you now have a superweapon?

"When did our 120mm gun have this power?" He Lao said: "In the previous report, wasn't it five hundred millimeters? ”

At the beginning, when selecting the artillery, Xie Huimin's confidence came from the depth of the artillery, which was 500 mm at that time, and it was also reported to everyone present, but in the end it was still defeated by 125 mm, not because of insufficient power, but because it was impossible to engage in an automatic loader!

They would not be willing to fail, and then after a period of sinking, at the suggestion of Qin Zhenhua, they were installed on the self-propelled chassis and turned into a self-propelled anti-tank gun.

However, at that time, it was just said that the barrel was stuffed in, but I didn't expect that the Second Machine Factory not only did this, but also tapped the potential of the 120-mm gun!

Even Qin Zhenhua was a little curious, how did you do it?

For example, the Germans' 120 mm tank gun, currently using the technology imported from Israel, using the overall tungsten alloy as the core, and increasing the length-to-diameter ratio, has only reached this order of magnitude, but what about their own? Of course, the double diameter of their own side is larger, and the 50 times the caliber must exceed the 44 times the caliber, so that the compromise has reached a depth of 500 mm, which is already the strongest.

How is it possible to increase the performance by another 10 percent?
