The world's first mass-produced tank gas turbine engine GTD-1000T was created at the Klimov Plant in 1968 for the T-80 main battle tank developed By the special tank design Bureau of the Kirov plant (now JSC "Spetsmash"), which was adopted by the Soviet Army in 1976. Since 1980, a modification of the GTD‑1000TF for T-80B/BV tanks was produced, since 1986 a modification of the GTD-1250 for T-80U tanks. GTD-1250 Engines of the GTD-1250 family as part of the power plants of T-80 tanks are in service with the armies of Russia, Belarus, Cyprus, South Korea, Kazakhstan. Turbine engine GTD-1000T/GTD-1250, which have a large volume-weight capacity and a more favourable traction characteristic compared to diesel engines, provide T-80 tanks with interesting characteristics: - higher operational readiness - easy start-up at low temperatures (up to -40°C) - better cross-country ability on soils with a low load-bearing capacity - best noise and heat-masking qualities - increased ...
When covering Soviet sight technology, there are always some interesting designs and approaches to solving an issue. It is a common fact that the Soviet Union in the 1980s-1990s was quite behind in thermal sight technology. Only in the 1990s, but to be specific in 1992, did the Soviet Union, now Russia, start to field small batches of thermal sights on their tanks, primarily T-80Us and some of the early T-90 variants, which had just recently entered service. Russia's journey through creating its own domestic thermal sight traces back to 1982. The 1980s were quite an important time for the 'Krasnogorsk Factory named after S.A. Zverev', which is still to date, an optical Engineering and optoelectronics factory. The factory is primarily known for making domestic Soviet cameras back in the day. However, that's not the only thing that the factory produced back then. Close to the mid-1980s, the facility was contracted to develop new thermal sight technology for the Soviet M...
One of the effective ways to improve the amphibious capabilities of a tracked propulsion system is to equip it with so‑called turbine blades. The leading edges of the blades face inward toward the track loop, and the trailing edges face the ground, which means they must not protrude beyond the supporting surface of the track. When the track rotates in water, the profiled surface of the blades generates hydrodynamic lift and horizontal thrust, the projection of which provides additional traction force. Such a propulsion system was used in the early 1950s on the American LVTP‑5 vehicle, which demonstrated very high water speed (11.2 km/h) with an 18.9 kW/t (25.7 hp/t) power-to-weight ratio. This speed was achieved thanks to the large width of the turbine blades located in the middle part of the track links. The principle of turbine blades can also be implemented, as done on the tracks of the Swedish IKV‑91 light tank , where small turbine blades were placed on both sides of the track, pr...
