Chapter 487: Chicken Rib Design

Qin Zhenhua has always emphasized that the potential of the 12150 diesel engine has been tapped, and the biggest problem is the heat dissipation problem caused by the small cylinder heart distance, which is even unsolvable.

Originally, everyone still didn't think so, and didn't go to their hearts, but with the 1000 horsepower diesel engine on the bench, Zhang Baolin has realized that this problem may really be the biggest problem restricting its power improvement.

If it is improved, isn't it the diesel engine project that is currently being developed by a machine factory?

The team led by Zhang Baolin is currently working hard to solve the heat dissipation problem, and after reaching 1000 horsepower, no matter how to increase the radiator, it will be found that the water temperature of the engine will rise quickly, and then it will not be reduced, accompanied by other problems such as bursting cylinder heads, not to mention.

This time I heard that the T-72 tank was brought back, Zhang Baolin was also very excited, hoping to find some experience from this diesel engine and use it to improve his diesel engine, but who would have thought that Qin Zhenhua poured such a basin of cold water on him.

800 horsepower, it is already the limit, look at the Soviets 780 horsepower diesel engine, overheating in the desert, it is already inevitable, you can only reduce the power to operate, how to improve heat dissipation, it is useless!

If this is the case, then there is a problem with their route, and if there is a problem with the route, no matter how much research is studied, it is impossible to make progress.

Zhang Baolin had such an ominous premonition in his heart, but now, his face still couldn't show it, he looked at Qin Zhenhua, Zhang Baolin's face was replaced with confidence, you said no, pour cold water on us, just woke us up, we will continue to study carefully until these problems are solved.

"Only competition will have development, and there is still satisfactory motivation in our industry." Zhang Lao watched the confrontation between the two with a smile on his face: "It's a shame to sit and wait for pie to fall from the sky." ”

Zhang Lao's emotion is still aimed at Qin Zhenhua's words, it seems that Qin Zhenhua's influence is getting bigger and bigger, and his words today also represent those who have already obtained benefits from the drill camp, and it is estimated that they will have to spit out the benefits again.

After all, who would dare not listen to Zhang Lao?

"This engine of the Soviets, another feature, is that it is a multi-fuel hybrid engine." Wang Tianming continued: "Our domestic engine, can we also refer to the design of this engine? ”

Since the Second World War, the diesel engine has shown quite good performance, it is durable, fuel-efficient horsepower, the same fuel tank, the endurance of the diesel engine is several times that of the gasoline engine, so, after World War II, almost all tank engines are diesel engines.

The tank is a monster that drinks oil, and the fuel supply of the tank is a big problem, on the battlefield, if the tank urgently needs to be refueled, but there are only different types of fuel on the scene, what should be done at this time?

At this time, the multi-fuel hybrid engine has an advantage.

The B-46 diesel engine used in the T-72 tank in front of us is a product of this idea, which can burn diesel, kerosene, and gasoline with octane numbers 68 to 78, as well as a mixture of these fuels.

In the driver's position, there is a special runner with the letters Д, К and Б, different positions, different oils are used, and even when it is needed, mixed fuel can be used.

As the overall designer of the tank, I am very interested in this function, and for the engine designer, this means that I have to put in more effort, and I can't even get a diesel engine, and now I want to make it a multi-fuel hybrid engine?

Qin Zhenhua smiled: "Yes, the technology is not complicated, but, as far as I know, whether it is the Soviets or the desert people, the T-72 they are equipped with has not been filled with other fuel once." ”

"Why?"

"Because the tankmen are afraid of trouble." Qin Zhenhua said: "If they fill other fuel, after the training, they have to re-clean the oil circuit, replace various parts such as filters, on the surface it seems to meet the needs of the battlefield, but in practice, it is too complicated, if they have gasoline on hand, they would rather wait for the diesel supply truck, than refill on the spot." ”

"As for us, it's even less practical." Qin Zhenhua continued: "Our army is almost all diesel engines, and the main fuel supplied by the troops is also diesel, so do you have to worry about only gasoline? It should be a 212 jeep, so it's better to think about how to fill up with diesel, right? ”

Everyone suddenly realized.

A lot of things are beautiful to say, and there are many factors to consider when designing, but when you actually use them, it's not like that.

It's like a folding bicycle, it's meant to be small and easy to carry, but when it's really time to use it, how many of them will fold it?

"The deck in front of it is also very interesting." After discussing the engine in the back, everyone looked at the front deck again, and looked at the unique V-shaped structure on it, which was very strange.

For a tank, the deck in front of the hull is also the main armor, except for the gun shield, the thickest place, now, the front deck of this tank is with a V-shaped structure, and on this V-shaped structure, there are also transverse stiffeners.

On previous tanks, almost never seen.

"This is also a chicken rib design." Qin Zhenhua said: "The scientific name of this thing is called a waveproof board. It is meant to stop the water from pouring into the cab. ”

Tanks, how to prevent the influx of water? Tanks turned into ships?

It's really like this, in the test of the tank, there is an aspect of wading, the tank encounters a creek or something, it can drive directly over, as long as the water does not flood the turret, there is no problem.

Of course, there is a way to drown, the tank will have a special snorkel, and even more than ten meters high, the tank groped forward in the water more than ten meters down, this snorkel can ensure the breathing of the members of the body and the use of the engine, and even at the top of the snorkel, there can be a person crawling, there is a command.

Of course, this function is exclusive to any tank soldier, and it belongs to the super VIP chicken ribs among the chicken ribs.

Cross a creek more than a meter deep, and forget it. It's so deep, it's better to wait for the sappers to build a bridge.

If it rains heavily, you can see that the front of the car will push the water to both sides, so the water surface on the engine cover is actually lower than the normal water surface.

This V-shaped wave protection plate is also designed with this concept, its V-shaped design can effectively prevent the front wave phenomenon, and divert the waves to both sides without splashing into the cockpit in the middle of the front of the car. Of course, at this time, the driver is driving with his head exposed, and if the overhead hatch is closed, it doesn't matter.

At the same time, in the interior of this V-shape, those horizontal stiffeners can increase the protective effect, in case the armor-piercing bullet that does not have long eyes hits the stiffeners, the holes that need to be drilled through will be even deeper.

In short, these designs should be taken for granted, some models of the T-64 also have this V-shaped mechanism, but soon, the explosive reactive armor was paved and disappeared.
