In Russia, following the resumption of production of T-80 tanks, the production of GTD-1250 gas turbine engines will also be revived. For now, the Kaluga Engine plant is restoring the engines of T-80 tanks, but preparations are already beginning for the production of new engines for tanks. Presenter Alexey Egorov visited the plant and showed the process of creating parts for new engines, casting molds and creating the impeller of the first stage of a gas turbine engine. Now the plant plans to begin producing engines with a capacity of 1,500 hp by 2025. Tankers love to drive T-80 tanks, as they are powerful, easy to start and allow you to quietly get close to the enemy at a distance of 100 to 200 meters, the sound of the tank at the beginning of the video. There are many opponents of the production of gas turbine engines for tanks, but gas turbine engines are also installed on American M1 Abrams tanks. The fact is that with the same power as a diesel engine, a gas turbine engine has less weight, is reliable and less noisy, and starts better at low temperatures. It is also worth noting tens of times less oil consumption. The disadvantages of these engines are high cost, difficulty of maintenance and high fuel consumption. According to test results, the T-80 tank had 60-80% more fuel consumption than the T-64 and T-72 tanks. Since the appearance of the first T-80 tanks in 1976, they were equipped with GTD-1000T engines with a power of 1000 hp; from 1980 to 1986, modifications of the GTD-1000TF engines were produced for the T-80B and T-80BV tanks with a power of 1100 hp .hp, since 1986, the GTD-1250 modification for T-80U tanks with a power of 1250 hp went into production; this modification is now the main one and is installed on all T-80 tanks. There were also GTD-1400 engines, this is the serial GTD-1250 engine with a short-term power boost to 1400 hp. And the GTD-1500 “product 39” engine with a power of 1500 hp, created using the latest materials. In total, more than 10,000 tanks with GTD-1000T/1250 engines were produced
