The Kharkiv Morozov Machine-building Design Bureau (KMDB) is one of the leading enterprises engaged in developing main battle tanks. Side by side with development of new tank designs, the KMDB carries out modernization of the tanks that were manufactured earlier, viz. T-72, T-62, T-55 and T-54 tanks.
The modernization is performed in three main directions:
Modernization can be carried out either in any of the above directions separately or in any of their combinations.
Additional measures are taken to decrease the probability of being detected by the enemy, to increase crew survivability, etc.
Modernization of the power pack compartment of the T-62 tank envisages installation of the 5TDF diesel engine developing 700 hp, side gearboxes, and efficient engine systems.
|Type||Multi-fuel liquid cooled diesel engine with opposed pistons|
|Power output, kW (hp)||515 (700)|
|Number of cylinders||5|
|Placement of cylinders||Horizontal|
|Specific fuel consumption, g/kW.h (g/hp.h)||240 (178)|
|Specific oil consumption at maximum power output, g/kW h (g/hp h)||5,9 (8)|
|Crankshaft rotational speed at maximum power output, rpm||2 800|
|Generator power output, kW||10 or 18|
|Engine weight, kg||1043|
|length, mm||1 413|
|Working ambient temperature range, °C||-40 to +55|
Modernization of the power pack compartment can be carried out at small enterprises in the shops equipped with lifting equipment with capacity of up to 15 t, metal-cutting equipment (plasma cutting or gas cutting)and welding equipment (up to 600 A).
Technological scheme of modernization of the T-62 tank:
In order increase the level of armor protection, the following is installed on the T-62 tank:
Efficiency of increase of armor protection of the upgraded T-62 tank:
The modular design of armoring the frontal part of the hull and turret has the following advantages:
The time required for installation of the removable armor module does not exceed 1 hour.
Modernization of the T-62 tank protection can be carried out at small enterprises in the shops equipped with lifting equipment with capacity of at least 1.5 t, metal-cutting equipment (plasma cutting or gas cutting) and welding equipment (up to 600A).
The tank can be equipped with the additional armor protection array within 20 days by 6 person.
In order to increase of the tank against anti-tank guided weapons (that have either semi-automatic tracer-guided control system or semi-active laser-guided homing heads), the tank can be equipped with the optical/electronic counter-measure system.
The system in question includes an optical/electronic suppression equipment and aerosol screen laying system.
The optical/electronic counter-measure ensures the following:
decoying away incoming anti-tank guided missiles by means of setting light interference within a sector of ±20° relative to the main gun bore in the horizontal plane and ±2° in the vertical plane;
suppression of control systems of laser beam riding anti-tank guided missiles equipped with laser semi-active homing heads by means of setting quickly-generated aerosol screens a sector of ±45° relative to main gun bore.
In order to increase protection of the tank crew against mass destruction weapons, the upgraded T-62 tank is equipped with an NBC protection system intended to ensure air-tightness of the crew compartment, fire/explosion suppression, filtration of the air that comes into the crew compartment. The system comes into action automatically with simultaneous audible and light signaling. When the tank operates under condition of radioactive contamination of terrain, the NBC system enables the crew to carry out measurements of gamma radiation within the range of 0.9 to 150 r/h.
