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

BMP-3 with "Karkas-1"/"Karkas-2" ERA packages

-
Image
  Shown at an exhibition in Omsk in 2001. ERA  blocks are located on the side and frontal parts of the hull and turret together with rubber fabric and lattice screens.  Additional protection significantly increases the survivability of the BMP-3. Advertising information of those years stated that the BMP-3 with the "Karkas-1"/"Karkas-2" was capable of withstanding the impact of HEAT grenades (RPG) with armour penetration up to 550 mm.  Also, reactive armour blocks increase the armour's resistance to damage from bullets of 14.5 mm calibre. Only known image of a BMP-3M swimming with the additional armour package. Further topic on BMP-3 ERA package

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

-
Image
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

BMP-3 ERA topic continuation

-
Image
This post expands on a previously covered topic, being the BMP-3 with ERA . Potentially sealing this topic until later when more information comes to light.  ERA package components:  ERA containers filled with 4S24 ERA elements, containers are mounted on the front and both sides of the hull. Slat armour mounted on the rear of the vehicle protects the engine compartment. Overall package performance:  Protection against AT rocket-propelled grenades (RPG) PG-7V, PG-7VS, PG-7VL, PG-7VM, PG-9S and other types of grenades capable of penetrating up to 600mm RHA within a 180 ° fire arc.  In areas covered by ERA containers, the probability of protection is at least 80%.  In areas covered by slat armour, the probability of protection is at least 50%. Protection against small arms:  Areas covered by ERA containers 12.7mm B-32 rounds at 0m within 180 ° fire arc 14.5mm B-32 rounds at 50 m within 180 ° fire arc Areas covered by slat armour and steel plates 12.7mm B-32 rounds at 35 0m within 180 ° fi
