FIELD: weapons and ammunition; blasting.

SUBSTANCE: invention relates to aircraft fuses. Fuse includes a housing, an arming unit with an electric igniter and retarder. Latter are integrated by common sealed cavity. Also includes an electric filter, composite reaction striker made in form of a rod, a striker and pressure nut. Furthermore, it comprises an inertial striker with spring-loaded ignition cap and transfer detonator, a spring-loaded firing device, sleeve with pyrotechnic composition, side sleeve, detonator and electric rope with contact unit. Fuse is equipped with an arming indicator and mechanical safety device. Arming indicator is made in form of mounted in sleeve housing with membrane tightly fitted therein and installed with possibility of movement along axis of sleeve stepped rod. One end of rod is made for contact with membrane, wherein its diameter is 0.5÷0.9 diameter of membrane. Second end of rod is arranged in hole made in housing. Mechanical safety device is made in form of mounted in housing a guide bushing installed in sleeve with possibility of longitudinal movement over inertial striker and fork and a sealing gasket. Width of neck of fork of fork-like part exceeds diameter of spring firing device. Furthermore, it comprises pivotally connected with fork a cylindrical part with an annular groove, and a cap. In bottom of cap there is an eight-shaped hole for accommodating bottom of cap in annular groove of cylindrical part of safety device.

EFFECT: higher safety of fuse by preventing random operation of fuse.
