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

-

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...

GTD-1000T - Koblenz, Germany

A big thank you to Mande for providing these images of the GTD-1000T that rests in Koblenz.  Having looked at the images, the engine has seen use; this can be noticed by the amount of soot in the exhaust duct. Additionally, there are several critical cracks that formed on the top right of the turbine housing. The lower ventilator that is used to provide fresh air to sub-components of the turbine and cool the engine bay is missing the housing, which seems to have broken off.  Overall, a decent exposition and well-made section cuts to show the inner assembly of the turbine and gearbox drives.

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" -...
