Chapter 1254 T-80UD
Forward, forward! Tanks are racing along the highways 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. Generally speaking, they are quite similar to the T-72. However, the front end of its body does not have the special V-shaped structure of the T-72!
This tank is the T-80 tank equipped by the Soviet Union itself and has never been exported!

This unit is also a meritorious unit, the 21st Guards Red Banner Vitebsk Tank Division, which was awarded the Order of Lenin and the Order of Suvorov and was stationed in the 35th Red Banner Army in the Amur Region! After Alaska was liberated, they were stationed in Alaska. From that time on, every soldier in the unit was full of energy, and they looked forward to the day when they could set foot on the evil American empire and liberate the proletariat here.
They watched the Mexicans take action, watched their German companions take action, and now, finally, it was their turn to take action!
The one rushing in the front is the 18th Tank Battalion. A few years ago, they were equipped with T-62 tanks. Later, they upgraded their equipment to the current T-80!
However, the unique howling sound of the gas turbine is gone. This T-80 tank has abandoned the gas turbine and adopted the latest diesel engine!

Gas turbines do have many advantages. They are easy to start, have strong overload resistance, and are not prone to stalling like diesel engines. But at the same time, they also have a disadvantage that cannot be overcome, which is that their fuel consumption is too high!
Historically, after the Soviet Union developed the T-80, it continued to improve it. In 1985, the T-80U officially appeared, which used a new generation of gas turbines GTD-1250. This engine has been greatly improved, using many advanced technologies, such as the radial airflow compressor blade cover and the automatic dust removal system of the high-pressure turbine nozzle assembly, the variable power turbine nozzle assembly, and the built-in reduction gearbox, etc., which increased the power to 1250 horsepower, but it still could not solve the problem of high fuel consumption.
At the same time, other design bureaus were 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 the T-80UD "Birch". Using the 6TD-1 type 6-cylinder multi-fuel two-stroke turbo piston supercharged diesel engine with a power of 1,000 horsepower, the fuel consumption is much lower.

Andrei's time travel sentenced the gas turbine to death in advance, and Soviet tank engineers began to develop the diesel engine version.
Back then, during World War II, Soviet tanks pioneered the use of diesel engines. The B2 series diesel engines at the time were epoch-making. Even the B-46 diesel engine of the later T-72 was based on the B2 diesel engine.
Soviet tank designers were familiar with developing diesel engines, and German engineers also joined in the process.

In terms of industrial technology, the Germans are also very good. The MTU873 diesel engine of the Leopard 2 tank can be said to be the limit of the power of tank diesel engines now! (Huadong Zhixiong is an absolute Leopard 2 fan and has always talked about the Leopard 2 tank with great relish.)
Therefore, when the Soviet Union replaced its equipment, it also planned to directly take the power of the Leopard 2 tank. After all, the advancement of this power system was obvious to all, and the Soviets were ashamed of themselves.
However, after some research, I finally gave up.

Why? Because I can’t let go!
The volume of the MTU873 diesel engine is 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, so this engine cannot be forced in, unless the T-80 body is lengthened and a pair of road wheels are added, which is tantamount to developing a new tank!
So, 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. The Soviet Union was originally developing it, and now, with the participation of German engineers, the project is progressing faster. Using German technology for transformation, this 3.15 cubic meter engine finally reached a power of 1,200 horsepower!
This is not abnormal, the volume of the power transmission room of the M1 tank is as high as 7.6 cubic meters! This is because the power unit uses an axial compressor and heat exchanger and a two-stage air filter, in which the volume of the air filter is about 2 cubic meters!

Although there is still a gap with the 1500 horsepower of the TU873 diesel engine, this engine is quite compact and is the most suitable engine for the power compartment of the T-80! Moreover, although the engine of the Leopard 2 tank is nominally 1500 horsepower, due to the dissipation of the cooling system and the consumption of various hydraulic transmission systems, 400 horsepower of power is wasted, and the power actually transmitted to the track is less than 1000 horsepower. In addition, the Leopard 2 tank weighs up to 60 tons, so in terms of mobility, the current T-80 is incomparably outstanding!
Moreover, after switching to the current diesel engine, the off-road range has doubled!
There are some disadvantages. Once this system is damaged on the battlefield, it is very troublesome to repair. Moreover, the replacement of the entire power pack is somewhat complicated, which 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 the power, the armor has also been updated, using the latest Soviet technology, honeycomb constrained ceramic composite armor. This welded and sealed entire armor structure is made into replaceable armor modules, which is convenient for replacement on the battlefield. As for the protection, the armor used by the Soviets is definitely much stronger than the exported T-72!

In fact, as of now, there is nothing that can stop the attack of the Soviet ground forces! You know, the Soviet Union is the most traditional land power!
At the same time, since the Soviet Union has decided to show its fangs, there is no need to be polite anymore. Just show up what needs to be shown!
Battalion commander Maxim exposed half of his body and looked at the fighter planes flying in the sky.
This time, the Soviets were serious. In order to protect their ground forces, the Soviets dispatched a large number of air force units!
