TECHNICS / EQUIPMENT
30 Type ZAB – 2.5T incendiary aerial bomblets
These bomblets are designed to ignite objects
of various types. They have a thin-walled,
steel body, with an AM
-
B head detonator and
a wing stabilizer. The charge is thermite, which
is initiated when the bomb hits the target.
After detonation, it creates one concentrated
focus of fire. It burns for 140 seconds at
a temperature of 2500oC and burns even under
water, burning through sheet metal 4-5 mm
thick.
Weight of Bomblet: 2.5kg, Length: 370mm,
Diameter: 60mm, Weight of Thermite explosive:
1.4kg
Color coding: one red band on the cylindrical
part of the body indicating the caliber, type of
detonator and cartridge used, manufacturer's
code, series and year of manufacture.
30 Anti-tank PTAB-2.5 cumulative
aerial bombs
These items are designed to destroy armored
targets with plating thickness up to 120 mm,
through the cumulative effect of the bomb
charge. When hitting the target, a fragmentation
effect is also created. In the body, with
a wall thickness of 3.5 mm, there is
a cumulative cup and the explosive charge is
a mixture of TNT and hexogen. It has a cylindrical
stabilizer and an ADC type bottom fuse.
Weight: 2.23kg, Length: 362mm, Diameter:
60mm, Explosive Weight: 0.4kg
Color coding: two purple bands on the
cylindrical part of the body. The cylindrical
part of the body is stenciled in black indicating
the type and caliber of the bomb, the type of
fuse and explosive.
Function: – After the submunition is released
from the container, the propeller is unscrewed
and separated from the detonator with the cap.
This unlocks the detonator and is fully ready for
operation. When the bomb hits a soft obstacle,
the membrane inside the detonator is dented,
soil or water enters the detonator hole and
acts on the striking mechanism. The needle
puncture causes the detonator to detonate and
the bomb itself (submunition) to explode. When
it hits a hard target, the impact deforms the
head part of the detonator at its weakest point
and the deformed part of the body then acts as
a striking mechanism and the explosive in the
bomb goes off.
