The RLV-TB round is intended for combined destruction, both by air-blast and thermal emission: of the enemy manpower and equipment located mainly in different types shelters and covered areas, and in the open, as well as of light armoured and unarmoured vehicles.
The 40×46 mm Round RLV-TB consist of Thermobaric Grenade with AF41 fuze and Propellant charge CP-42. At a safe distance 10m, after the grenade has left the barrel, the fuze gets armed. Upon meeting a target, the fuze AF41 gets activated and initiates the bursting charge which, in its turn, disperses the thermobaric composition TBC-2.
The thermobaric composition TBC-2 interacts with the oxygen from the air; an air-fuel composition is generated which detonates from the bursting charge. A zone characterized with over pressure and temperature is created in the area.
The round is designed for use with 40×46 mm Underbarrel Grenade Launcher UBGL-M6 and its modifications, as well as M203; HK 69; etc.
The rounds can be stored in non-heated storerooms for 10 years, but only if they are kept in the original non-opened packing of the manufacturer.
