T-90A/S Object 188A1(S) with KE2K

-

 A prototype version of T-90A/S equipped with the KE2K power/air conditioning unit, designed by SPA "Electromashina". KE2K is mounted in the rear of the turret, replacing the spare parts container. This unit was designed to provide the crew with stable temperatures in extreme climates, help cool the gunners thermal imaging sight and act as an APU to provide additional power. 


The power unit-air conditioner, developed and manufactured by SPA "Elektromashina", is intended for;

    - cooling of electronic devices, incl. thermal imager "ESSA"
    - preservation of the resource of the main engine
    - power supply of electrical equipment of the tank (weapons, radio station, etc.) for when the main engine is not used
    - automatic charging of the main storage batteries
    - increasing the efficiency of the crew



Output voltage: 27.5 V

Power produced: 
    - in air conditioner mode - 0.5-4 kW
    - in power unit mode - 6.5 kW

Number of cooling units - 4

Time of continuous operation without refuelling - 8 hours.

Dimensions of the main cooling unit


KE2K was mounted on a T-90S tank for testing in January-February of 2010. The T-90S with KE2K did not get past testing phases and was never put into production.

Modelling AFV detection parameters using thermal imaging reconnaissance

-
Image
In the 1980s, the Soviet Union determined that the widespread use of thermal imaging devices for reconnaissance majorly outperformed the maximum detection ranges of devices based on electro-optical image converters. It was rated that these new thermal imaging systems had ranges of 3km compared to electro-optical image converters with ranges of 1,5k-2km. To mask AFVs from thermal reconnaissance means, it was determined to create algorithms that would compute a thermal imaging result based on variables like thermal emission and background (ambient temperature). The simulated detection process went as follows; search for targets in a specific area, find a target with higher display contrast than the surrounding area and identify the target through a poorly detailed silhouette.  To avoid complexity, the article will not cover the entire computing algorithm.  Algorithm used to form thermal imaging result Thermal imaging result based on the computed algorithm  It is stated that the distance

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 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
