"The main function of an infantry fighting vehicle is to provide protection for armored infantry that cooperates with tank operations, and further provide medium and short-range fire support for infantry. In this way, the tank is mainly responsible for attacking long-range large equipment and fortifications, and armored vehicles attacking short-range fortifications and light equipment. Infantry is near-ground combat to protect armored vehicles and tanks. A far, medium and near firepower network is formed on the battlefield..." Liu Yijiu explained to everyone.

He had to change their ideas.

In some aspects, it is best to be integrated and multifunctional, but in some aspects, it must be specialized and subdivided.

This is very contradictory, but the development of weapons and equipment is like this. In this era, the military industry development took many detours, and Liu Yijiu couldn't even understand what it is necessary to equip a large-caliber gun on infantry fighting vehicles.

In urban combat, there are heavy artillery groups in the rear, and the sky has aircraft and missiles that can be supported at any time. Although the tank's penetration ability is very strong, the speed of this thing cannot be accelerated. In close-range street battles, it is easy to be regarded as a target and fall into a trap.

And tanks are more beneficial than tanks in street combat.

In the war in the wild, sometimes tanks will not even be as flexible as infantry fighting vehicles, and their combat capabilities will not be too high.

The planes in the sky cannot be prepared for tanks and cannot run at speed, so they must be protected.

Infantry fighting vehicles will replace tanks in the future and become used for air defense and anti-armor and provide short-range fire support for the squad infantry. He wants to get on the armored vehicles directly, but without more advanced air defense and anti-armor missiles, he cannot maximize the power of the infantry fighting vehicles.

"In addition, if such a war occurs, the ground is far, medium and near firepower network is formed, and if the air is equipped with three-dimensional firepower strikes from helicopters and fighter jets, how many enemies can resist it in such a war situation?" Liu Yijiu's words made everyone think.

"Director Liu, let's do it according to this?" Jiang Ming didn't know how much role the war monster on the drawing in front of him could play after it came down. However, due to the existence of anti-tanks and air defense missiles, this attack power is at least many times stronger than the 59 tanks currently equipped in China.

At the same time, although there are fewer coaxial machine guns, their ability to produce on the battlefield will be much higher.

Air-defense machine guns are mainly air defense, but under the current circumstances, this thing will be transformed into high-level dual-purpose, and they are mainly used to shoot infantry on the ground! If equipped with two thousand bullets...

"The automatic loading mechanism of t72 is used inside to reduce one operator, which will increase a lot of space. In addition, the layout of the ammunition compartment and the crew compartment needs to be modified. This way..." Liu Yijiu said while drawing the layout inside on the drawings.

In the internal layout, he directly adopted the xm1 cockpit and ammunition warehouse layout method, rather than the Su-style type that directly stores the shells under the tank's turret. Once hit, it is easy to explode.

He even planned to change the front-wheel drive to rear-wheel drive, and add a pair of steering wheels to the original steering wheel position in the front, which means turning the original five-wheel pair into six-wheel pairs. Finally, he thought about the solution that it was too difficult to implement. He had to redesign the territory, which was simply unrealistic.

So I had to give up. Although this has great benefits for the flexibility of the tank, it is not very easy for China, which has weak technology to achieve.

"Director Liu, I have another question. If we use the welded turret we currently use, will the strength and protection force be weakened?" Chen Wei always felt a little awkward to abandon the tank that has always used round turrets.

At the beginning, the original circular turret was used on the design drawing, but now when Liu Yijiu was drawing the internal layout, he found that the circular turret would make the space smaller.

I simply changed the circular turret to the design with a large inclination angle of xm1.

"According to our research, the inclined surface with a large incline angle seems to be much higher than the design without a incline..." Cao Feng saw these changes of Liu Yijiu and his eyes were shining brightly.

With this design, it is easier to install reactive armor.

Only by using welded armor can the entire armor be realized more easily. According to their design, there are seven layers of main armor on the front of the turret! The thickness of homogeneous steel armor is only more than 20 cm, mainly to add a layer of carbon fiber with high strength on it... At the same time, the ceramic balls on it will also be embedded in this homogeneous steel armor...

These designs can effectively offset the kinetic energy of the armor-piercing bomb. In fact, two layers of hollow titanium tubes are arranged inside. This is mainly because the hollow tubes have a very big impact on the direction of the jet flow...

Outside, in order to prevent the fence-style shielding device of rockets that have begun to become flooded in the world and have become anti-tank artifacts. Anyway, Liu Yijiu used all the practical, low-cost technologies and designs of the Wujiu Magic Modification. He was too lazy to care whether this thing was beautiful in the end.

War weapons are not for people to use to pick up girls while driving to and from get off work, but for killing people.

The strongest firepower, the highest defense, the most flexible operating performance, and the strongest power system have reached a perfect balance on the territory of this Wujiu tank because of Liu Yijiu, a latecomer.

In the end, it is unknown whether it can become the strongest Wujiu Magic Modification in the world.

Anyway, he felt that no one would be able to surpass him in the future. Even the Soviets who designed the 54/55 series tanks would not work!

These designs are not very difficult to implement, but are based on a lot of research. Most of the technologies are from the late 20th century and early 21st century. This kind of tank after the magical modification is no longer 59, and there is no similarity in everything except the chassis.

This is also the preparation for the next step for Liu Yijiu to independently design a new generation of Republic main battle tanks that can compete with the overlords of the third-generation tanks such as xm1 and Leopard 2.

"You can try this at that time. My example is just a suggestion, not necessarily saying that it should be like this..." Liu Yijiu said with a smile.

Others laughed, and Liu Yijiu always did this. He said that the result was much better than the usual ones, and there was no need to waste time and money to experiment.

"In addition, a pressure relief plate must be installed behind the bullet cabin. When the bullet cabin is hit and causes a death explosion, the pressure of the explosion will be released upward or backward to avoid causing an impact on the front passenger compartment..." The Americans' research results were taken out and used directly.

As for whether the domestic technology is too poor, Liu Yijiu will not care about it. These masters will always come up with some solutions.

"The skirt on this side is not necessary, right? It's still twenty centimeters thick, which is hundreds of kilograms..."

"No, the skirts on the sides and front and back must be included. This can effectively protect the suspension system. At the same time, it can also block some dust. It is connected by threaded fasteners, which will make maintenance more convenient..." Liu Yijiu firmly disagrees to remove the skirts on both sides of the track.

While discussing and modifying it, in the end, if this thing was not for the tracks and 51 times the caliber 105 rifled gun barrel, no one would have thought it was a tank.

Even the 59 tank after the magic modification, according to the current design, has a total height of only 2. meters, which is more than ten centimeters shorter than the 2.4 of the American m1!

However, not many people who discussed with Liu Yijiu know.

"Basically, that's about it. For some other areas that everyone needs to improve, please slowly modify them during the experiment..." When the discussion was almost done, the outside was already lit up.

Another sleepless night.

"Director Xiao Liu, since we are focusing our main energy on this, should we put our armored infantry fighting vehicles in the back first?" He didn't sleep all night, and many things were something he didn't understand. Qian Dayong's spirit was not as excited as these technicians and was very tired.

There is a big difference between tanks and infantry fighting vehicles.

However, at the beginning, because they had no chassis plan, they could only use 59 tanks to design an infantry combat vehicle.

"No, it's completely unnecessary now. The fire control system can use the same one on both sides. As for the cannon, since everyone thinks it's more appropriate to use a 40mm cannon, there's no problem. Most technologies are universal, and even armor is fine, so naturally there's no need." Jiang Ming opposed it without waiting for Liu Yijiu to speak.

This tank will use a lot of new technologies. Although many of them are very difficult for them, Liu Yijiu's explanation made them feel that these things are not very difficult to achieve for the technical reserves in the Ninth Academy base. As for the electronic system, this can only leave room for upgrading in the future.

They currently need to create a prototype car to test firepower, defense, and even maneuver power.

If there is no problem, put the tank directly on the southwest battlefield for actual combat inspection.
