For each previous generation of tanks, the technology is not advanced enough, so tank designers must take care of it, for example, some must pay attention to firepower, as a weapon, of course, the first thing to fight the enemy can do, and some are to pay attention to protection, the life of the soldier is precious, on the battlefield, first protect yourself, in order to destroy the enemy.

Different ideas lead to different effects of tank design, some are more extreme, just like Israel, in order to protect the lives of its fighters, even put the engine in front, becoming an extreme tank that pays attention to protection.

As for focusing only on mobility? In the previous era, due to the limited power of the engine, if you want to maneuver fast, you can only reduce the armor protection, and the result is that it is a thin skin and a big filling, when during World War II, some fast tanks engaged in by the British were in accordance with this line of thinking.

And now, with the continuous development of technology, it is finally possible to consider the three together.

Take the Leopard 2 tank as an example, this kind of tank is a good compromise, because of the 1500 horsepower engine, super power, so that this tank can have a high enough weight, in the case of sufficient weight, it is natural to have enough armor protection, plus the advanced tank gun smelted by Germany's advanced industrial base, it can be said that the three have been effectively compromised, and the three indicators are balanced.

Now, if the French want to innovate, they have to build on these three elements and then improve, what is this improvement? What the French put forward is synthesis, integrating the needs of many infantry ground vehicles into a tank and becoming a comprehensive tank, which is naturally a step further than a tank that only has three major indicators of protection, firepower and mobility, which can be called a fourth-generation tank.

The French proudly began to introduce their vision that the French must be the most dazzling and charismatic in any place.

Qin Zhenhua's face at this time was holding back a smile, he had long known that the French liked to be amorous the most, and the same is true now, they took a future tank on paper to compare it with the current German tank and the tank of the Eagle Country, and belittled other people's tanks as worthless, which simply made people laugh off their big teeth.

To be honest, if you look at tanks, you really have to look at Germany, even if you look at the United States, you will never think of France, and now there is nothing that France can handle on the ground weapons!

Qin Zhenhua secretly thought in his heart, however, he came here mainly to learn more, and he would be less involved in this kind of dispute.

Being a listener is even better.

While he was thinking, he was thinking about looking around, Wang Xiaoyu, his wife, was holding a pen at this time, rustling on the paper to record, she cherished this opportunity to go abroad, and now this opportunity for academic exchanges, naturally she will not let go, what the other party says, she will remember.

It can be said that the wife who works seriously looks more charming, full of the unique charm of oriental women, how to look at it, how to like it.

Qin Zhenhua, you kid, you're lucky to have such a beautiful woman as a mother-in-law, so in the future, you must treat others well.

As if he knew what Qin Zhenhua was thinking in his heart, Wang Xiaoyu suddenly raised his head and glanced at Qin Zhenhua, his eyes were also full of love, which instantly made Qin Zhenhua's heart melt.

"The concept they said seems to make a lot of sense." At this moment, Huang Lao on the side whispered.

Qin Zhenhua focused his attention on the other party's speech, since the French want to claim that their tanks are fourth-generation tanks, they must come up with a new concept, and now, they are talking about a new concept.

"The engine must be compact, if there is no compact engine, it will bring unnecessary burden to the design of the entire tank, take it now, the tank we designed, the volume of the engine, only half of the Leopard-2 tank engine, so that the length of the entire hull, at least one meter of distance, this meter of length, and will lead to the weight of the hull, at least five tons, everyone, even if you all like large tanks, but, in the case of the same protection capacity, save a certain weight, Isn't it good? ”

The French are proud, and these ideas, when they say it, really make sense.

The Leopard-2 tank is good, but there are still criticisms, that is, the engine in the back, the volume of this engine is too large, especially with the addition of a radiator, it is even bigger, as a result, the tail of this tank is raised high, and at the same time, the weight of the tank has also increased a lot because of the volume of the engine.

Why is that?

Of course, it's the length.

The length of the back of the tank is for the engine, and the smaller the volume of the engine, the smaller the length of the back, as the French say, a reduction in length of one meter saves at least five tons of weight!

So, how can you reduce the length of the car body? It can only be achieved with a small engine! The compact engine is an important solution to reduce the length of the vehicle!

Qin Zhenhua's mind was also thinking rapidly, in fact, this also involved another aspect, that is, the layout of the longitudinal engine and the transverse engine.

For a long time, the Soviet tanks have a transverse engine layout, which gives the tank a relatively compact volume, while the Western engines are longitudinal layout, so the engine compartment is very large. Horizontal, or vertical?

Just like a sedan, the engine of an economical sedan is horizontally mounted and front-wheel drive, so it looks like the engine compartment is very short, while a luxury sedan is a longitudinal engine and rear-wheel drive, so the front of the car looks very long, of course, there are also strange things, such as a certain self-da, which is obviously a transverse engine, so you have to get a big front car, and the interior space is very narrow, and the engine compartment is empty.

It seems that you need to explore these by yourself, and other people's plans are just what people think is the most suitable, not necessarily suitable for themselves.

The engine of the Leopard-2 tank is basically a cube, and it makes no difference if you want to be placed horizontally and vertically, and the French see this flaw, so they deliberately take it out and criticize it, and the French have been targeting the German tanks, and it is clear that the French have grievances.
