MECHANICAL FUZE WITH SELF-DESTRUCT MECHANISM
A mechanical fuze for aerial ordnance devices having an extendable probe, and impact sensor mounted on the probe, an impact responsive inertia weight operable with an auxiliary firing pin as a backup for the probe sensor, and a self-destruct assembly. The self-destruct assembly includes a percussion primer actuated during extension of the probe and coupled to a thin column of deflagrating material sheathed in a flexible metal and having an explosive charge at its terminal portion for driving a piston against the inertia weight if both the probe sensor and inertia weight remain unactivated when the column burn front reaches the explosive charge, thereby detonating the device through the auxiliary firing pin.
