Fig.17 Installation of the AV-1D/U aerial bomb fuse into the bomb in the
nose configuration. The procedure is similar to that for the APUV-1 fuse.
When the MDV-5 arming device (not shown) was used, it released 1.9 ± 0.4
seconds after bomb release.

Purpose:
It is used to initiate AO fragmentation, OFAB high-explosive fragmentation, DAB smoke, and CP practice aerial bombs upon impact with the target.
Specifications:
Mechanical, impact, head, instantaneous, with a detonator (resulting in detonation on impact).
Main Components:
Fuse body (9) with a key slot (3) and a threaded stem with a diameter of 26mm,
Vane (1) with a locking cap (2),
Diaphragm (12),
Pin (4) with a piston (10) and a cap (11),
Plastic housing (8) for the pin,
Washer (5),
Detonator (7) in its housing (6).
Operation:
Upon the release of the bomb, the vane (1)
and its cap (2) are unlocked and unscrewed
by the force of the airflow, thereby arming
the fuse. When the bomb impacts soft ground,
the diaphragm (12), not shown in Fig.16, is
forced inward, and the soil exerts pressure
on the cover (11) and piston (10). This drives
the firing pin (4), guided by the sleeve (8),
into the detonator (7) housed in the casing
(6). Upon impact with hard material, the
fuse deforms at its weakest point, and this
deformed section subsequently acts upon
the cover and piston. If the bomb is dropped
unarmed, the vane (1) remains locked, and
the bomb does not explode upon impact.
