Red Soviet Union

Go on, go on! Tanks are running on the highway on the west coast of the United States.

These tanks have the usual low body structure of Soviet tanks, six pairs of road wheels, and a layer of reactive armor on the side of the turret. If you look at it in general, they are quite similar to the T-72, but its car The front end of the body, but it does not have the special V-shaped structure of the t-72!

This tank is the t-80 tank equipped by the Soviets themselves and never exported!

This unit is also a meritorious unit. It is stationed in the Red Banner 35th Army in Amur Oblast and won the Lenin Medal and the Suvorov Medal. After Alaska was liberated, they were stationed in Alaska. Since then, every soldier in the army has been full of enthusiasm. They look forward to the day when they can set foot on the evil American emperor and liberate the proletariat here.

They watched the Mexicans do it, watched their German counterparts do it, and now, they finally waited to do it themselves!

The 18th Tank Battalion rushed to the forefront. A few years ago, they were still equipped with t-62 tanks. Afterwards, the shotguns were replaced with guns, and their equipment became the current t-80!

It's just that the unique howling of the gas turbine is gone. This t-80 tank has given up the gas turbine and adopted the latest diesel engine!

Gas turbines do have many advantages, such as easy start-up, strong overload resistance, and unlike diesel engines, which do not stop at any time, but at the same time, this thing also has a disadvantage that cannot be overcome, that is, the fuel consumption rate is too high!

Historically, after the Soviet Union developed the t-80, it continued to improve. In 1985, the t-80u officially appeared, which used a new generation of gas turbine gtd-1250. This engine has been greatly improved and adopts many advanced technologies, such as the radial flow compressor fan blade cover plate and the automatic dust removal system of the high-pressure turbine nozzle assembly, the variable power turbine nozzle assembly, and the built-in reduction box, etc. Wait, the power has been increased to 1250 horsepower, but it still cannot solve the problem of high fuel consumption.

At the same time, other design bureaus are also improving the t-80. For example, in 1987, the Morozov Design Bureau independently completed the development of the t-80 diesel engine version, called t-80ud Birch. Using a 6td-1 type 6-cylinder multi-fuel two-stroke turbo-piston supercharged diesel engine with a power of 1000 horsepower, the fuel consumption is much smaller.

Andrei's crossing sentenced the gas turbine to death in advance, and the Soviet tank engineers continued to develop the diesel engine version.

At the beginning, during World War II, Soviet tanks pioneered the use of diesel engines. The b2 series diesel engines at that time were of epoch-making significance. Even the b-46 diesel engine of the later t-72 was also based on the b2 diesel engine. of.

The Soviet tank designers were familiar with the development of diesel engines. At the same time, German engineers joined in the process.

In terms of industrial technology, the Germans are also very powerful. The mtu873 diesel engine of the Leopard 2 tank can be said to be the limit of the power of the current tank diesel engine! (The hero of Huadong is an absolute Leopard 2 fan, and he has always talked about the Leopard 2 tank.)

Therefore, when the original equipment was changed, the Soviet Union also planned to directly pack the power of the Leopard 2 tank. After all, the advanced degree of this power system is obvious to all, and the Soviet Union is also ashamed.

However, after some research, I finally gave up.

why? Because I can't let go!

The volume of the mtu873 diesel engine is a full 3.69 cubic meters, while the gas turbine used by the t-80 is only 2.8 cubic meters! In later generations, the improved t-80ud is only 3.15 cubic meters. Therefore, this kind of engine cannot be plugged in. Unless the body of the t-80 is lengthened and a pair of road wheels is added, it is tantamount to Redeveloped a tank!

so,

Looking back, in the end, they chose their own product. This engine is not the b46 engine of the t-72, but the newly developed 6td diesel engine! This diesel engine is a horizontally opposed six-cylinder two-stroke multi-fuel supercharged engine. Originally, the Soviet Union was developing it by itself. Now, with German engineers joining in, the progress of the project has been accelerated. Using German technology for transformation, this engine with a volume of 3.15 cubic meters has finally reached a power of 1,200 horsepower!

This is not abnormal, the volume of the power transmission chamber of the m1 tank is as high as 7.6 cubic meters! That's because the powerplant employs an axial compressor and heat exchanger as well as a two-stage air filter, where the volume of the air filter is about 2 cubic meters!

Although there is still a gap between the 6td diesel engine and the 1500 horsepower of the mtu873 diesel engine, this engine is quite compact, and it is the most suitable engine for the power compartment of the t-80! Moreover, although the engine of the Leopard 2 tank is rated at 1,500 horsepower, due to the dissipation of the cooling system and the consumption of various hydraulic transmission systems, 400 horsepower is wasted in this way, and it is really transmitted to The power on the tracks is less than 1,000 horsepower, and the weight of the Leopard 2 tank is as high as 60 tons, so in terms of mobility, the current T-80 is extremely good!

Moreover, after switching to the current diesel engine, the off-road trip has also doubled!

In terms of shortcomings, there are also some. Once this system is damaged on the battlefield, it will be very troublesome to repair. Moreover, the replacement of the entire power pack is also a bit complicated. It is not as convenient and quick as the overall replacement of the power compartment of the Leopard 2 tank.

At the same time, in addition to power, the armor has also been updated, using the latest Soviet technology, honeycomb-bound ceramic composite armor. This welded and sealed entire armor structure is made into a replaceable armor module, which is convenient for replacement on the battlefield. As for the protection, the armor used by the Soviets is definitely much stronger than that of the exported T-72!

In fact, for now, there is nothing that can stop the attack of the Soviet ground forces! You know, the Soviet was originally the most traditional land power!

At the same time, since the Soviet has decided to show its fangs, there is no need to be polite, and what should be taken out, it should be taken out!

The battalion commander, Maxim, exposed half of his body, and he looked at the fighter planes flying by in the sky.

This time, the Soviet is serious. In order to protect its own ground forces, the Soviet dispatched a large number of aviation units!
