GTA-18A/GTA-18M-E APU

-


The GTA-18A gas-turbine-driven electric generator is designed for installation in vehicles to supply them with 18kW DC power without having the need to keep the main engine running. In addition to the standard utilization, the GTA-18A can be used to kick-start the main engine. 

The GTA-18A APU provides a constant supply of power to all onboard electronic devices of a tank. This drastically reduces the overall fuel consumption of the vehicle. 

To minimize the additional operation pressure on the crew, the entire generator pack is fitted with automatic safety devices. These devices monitor the generator and can safely shut it down, whenever one or several key components reach critical operation limits, such as pressure, oil temperature and gas temperatures exceeding recommended limits. 

The entire generator set consists of the GD-40 gas-turbine engine, GS-18MO/GS-18BT starter-generator, fuel system, oil system and electrical equipment. The APU is connected to the vehicle's main fuel system without the need to use external fuel tanks. The main turbine assembly is a multi-fuel single shaft unit fitted with a single-stage centrifugal compressor, single-stage axial-flow turbine, annular combustion chamber and a gear reduction unit. 

In addition to the standard GTA-18A, a modernized version is offered. The GTA-18M-E offers several upgrades that can be mounted. 
  • Increased power output to 24kW
  • Provision of additional fuel and oil systems to increase operation duration for more autonomous performance
  • Installation of a water-to-gas or air-to-gas heat exchanging unit for generating heat
  • Constant air heating up to 250-300 C
  • Equipped with welding equipment

"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-1000 - GTD-1000TF - GTD-1250 Gas Turbine Engines

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 &qu

A new sight for the modernized T-90

  Back in 2018, a new programme was started. This programme's focus is to create domestic equipment for Russian armoured vehicles, specifically optics. This is so that the Russian army can stop depending on the french company "Thales" and their Catherine technology. T-72B3 received new internal components for the Sosna-U sight, phasing out any foreign components. As for the T-90M/T-90MS, something else was done. Previously, the T-90M/T-90MS employed the Sosna-U sight, which featured french components from Thales. However, the internals of the sight was not simply replaced. This time, a completely new domestic sight was created under the name PNM-T. The sight was reportedly made by the PJSC ANPP TEMP-AVIA in 2018 or 2019. The first appearance was in the Telekanal Zvezda show, during the episode about the Proryv-3 (T-90M). In this episode, a new plaque can be seen with the name of the sight. Its first public physical appearance, however, was at the Army-2019 event. The doo
