Object 219 engine monobloc compatibility

-
Image
It is important to note that the GTD series of monoblocs, starting with the GTD-1000TF and ending with the GTD-1250, are boosted units of their previous model. This explains why certain monobloc types have 2 different power ratings based on their original power rating output before and after being boosted.  Monobloc types:  Type "R" with an engine power output of 1100 hp - "R-1.1" Type "R" with an engine power output of 1250 hp - "R-1.25" Type "RV" with an engine power output of 1100 hp - "RV-1.1" Type "RV" with an engine power output of 1250 hp - "R-1.25" Type "AS" with an engine power output of 1100 hp - "AS-1.1" Type "AS" with an engine power output of 1250 hp - "AS-1.25" Type "R" - Monoblocs with a transmission oil pump 219-14-sb740, are identified based on the power output:  "R-1.1" - 1100 hp  "R-1.25" - 1250 hp Type "RV" -...

"AGAVA" - "AGAVA-2" and its confusing history

-
Image
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, the Soviet Union now Russia started to field small batches of thermal sights on their tanks, primarily T-80Us and some of the early T-90 variants, which 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 has produced back then.  Close to the mid-1980s, the facility was contracted to develop new thermal sight technology for the Soviet Ministry...

T-80 aerodynamic features - Part 1

-
Image
This article is the first part of a set of articles covering the engineering and methodology used to create the T-80s filtration system alongside aerodynamics to reduce airflow dust/sand contamination.  The T-80 MBT has been fielded in many climate regions. Desert climates pose a variety of variables that directly impact dust presence in the engine air filtration system. Variables include wind speed and direction,  vehicle speed,  depth and soil composition, air intake system design, and contours of the hull and turret.    Historical background:  Long-term trials were conducted in the southern Kara-Kum desert. It was determined that during  1970-1983, the quantity of dust present in the engine filtration system increased due to climate changes and weaker upper soil layers.   During the 1970s to 1980s, the Turkmen Canal underwent Soviet industrialization to build an irrigation canal and other facilities. This build-up of new infras...
