Chapter 1942: Test decision

"In order to adapt to your bridges and other restrictions, the total weight of this tank is 48 tons. It has a good balance of firepower, mobility and protection." Qin Guan began to introduce.
The first indicator of a tank is its own weight, and everything starts under this premise.
For example, Western tanks are always 60 or 70 tons. This kind of weight has a fairly good protection capability and the space is large enough. However, this type of tank has high requirements on the road. These bridges have a weight limit of 50 tons, so they cannot be crossed. They need to be reinforced by engineers, and time will be wasted.
From a global perspective, the self-weight of tanks is constantly increasing. After all, for tankers, the stronger the steel box, the better. However, for tank designers, it must be balanced.
For the holy country, no more than 50 tons is the best. The current design is 48 tons. That is to leave a margin of 2 tons in case of future improvement. Qin Guan took all this into consideration.
With this indicator, you can continue. For example, if the self-weight does not exceed 50 tons, then six pairs of road wheels are enough. Many Western tanks have seven pairs of road wheels because their own weight is too large and there are few road wheels. It’s not enough, and the torque is too large for the torsion bar.
"Let's talk about its firepower first. This 125mm tank gun can be the same model as the Azira tank just mentioned. In this way, when you operate, it can greatly reduce the difficulty of logistics supply." Qin Guan said , Even Qin Guan just thought of this advantage. Originally, he planned to put 105mm guns on 59 tanks, so there are more types of logistical shells. Now they are all 125mm guns, and the tank guns are exactly the same. , In this way, logistics supplies can be reduced, which is really an unexpected benefit.
Balaj nodded: "That's right, in the future, our tanks will have a uniform caliber of 125 mm, and it will be much less difficult to supply logistics."
"Of course, this tank gun can also use the same semi-automatic loader as the Azira tank just mentioned, and it also has the option of automatic loading. It depends on the requirements of the specifications. Our domestic tanks, the test result is Very stable, but in the high temperature environment here, it still needs to be retested."
As Qin Guan said, he pointed to the round of shells in the turret. In fact, this Khalid tank originally used an automatic loader. This is an imitation of the automatic loader of the T-72 tank. However, because the domestic electronic technology and so on are more advanced, the processing accuracy is also high, so the reliability of the prototype automatic loader, etc. are solved. It can be said that this automatic loader is already very mature.
As for how to choose, it's their business, and it's just that we provide these equipment.
"Continuing to talk about its power system, for a 48-ton tank, the 1200 horsepower engine is enough. We have this kind of suitable engine in China. At the same time, you can also find out through procurement bidding. Western engines are used for testing, and we finally choose the most suitable one from them." Qin Guan said.
The domestically-made tank engines are already very good. At least on the 80 tanks ordered by the date palm country, the domestically-made engines are used. However, for the brothers of the holy country, Qin Guan is very generous. Let them choose by themselves. There are many options.
When ordering warships, people were able to get LM2500 gas turbines from Eagle Country, and they were free of money. It was completely military aid. If they could get a free engine from abroad, of course it would be better. Just responsible for integration.
When Qin Guan said this, Balaj raised his own question: "Now, Xiong Country and Ying Country are all starting to build gas turbine tanks. Is this kind of engine better?"
Xiong Guo’s T-80 uses a GTD-1250 gas turbine with a rated speed of 3300 per minute and a maximum power of 920KW. The AGT-1500 gas turbine used by Eagle Country on the M-1 tank has a rated speed of 3000 per minute and a maximum power of 1119KW.
Both are gas turbines with three-shaft structure, very similar, except that AGT-1500 is equipped with intercooling and recuperation devices in order to pursue higher energy utilization.
Since the Eagle Country and the Bear Country are the most advanced in technology, their choice represents a direction. Therefore, since they want to build a new tank, even General Balaj has this idea. Can we get a gas turbine?
Facing the other party’s question, Qin Guan said,
Well, let’s try it. I think we can get the T-80 gas turbine from some channels, and the power is just enough and the size is good. "
If it was before, Qin Guan would immediately make a decision, gas turbine? Is it affordable? That is a must-have for local tyrants. There is no oil field at home, so dare you use that stuff?
But now, Qin Guan’s thinking has changed a bit. After all, this thing still has some advantages. Compared with the diesel engine, its biggest feature is that it will not stall. You can operate it, and the engine will not stall. At the same time , Which also means that its torque is extremely powerful, and the acceleration is quite good.
As for the others, don't say anything about fast startup, high power density, etc.
In the past, Qin Guan didn’t do it because he knew that this kind of thing burned too much oil and it was definitely inappropriate in the country. So when the country developed, he directly rejected it, but it’s different now. Develop it for the Holy Nation. Since they want to use it, they can test it out. Anyway, if they have the time, energy, and atmosphere for this kind of research, they can treat it as a scientific research project, and let domestic tank experts. Let's see if this gas turbine is reliable or not.
After the test, the Holy Nation estimated that it would not purchase it. After all, they have limited funds. After several tests, they found that drinking oil is just like drinking water, and it will definitely be put on the shelf.
In fact, this is mainly because this thing is weird, idling and high speed, fuel consumption is the same.
Ordinary diesel engines consume very low idling fuel, so some drivers are reluctant to burn fuel, and almost all of them are idling during the whole drive. They think that they have saved a lot. A 150-horsepower machine has only used 30 horsepower. In fact, carbon deposits and the like will cause the engine to be scrapped earlier, but fuel saving is indeed fuel saving.
But the gas turbine is different. Idle speed and high-speed operation have the same fuel consumption rate. Especially when it is on standby, it has been idling, and the fuel has been consumed. When it is needed, the result cannot go up. This is T-80 The saddest scene in the bear country's civil war.
Of course, there is also a solution, which is to add an auxiliary power unit and not start the gas turbine. Now that we are talking about it, we also have time and money to carry out these tests and pre-research.
Firepower and maneuvering are all finished, and the rest is protection.
