ABSTRACT:
A single ordnance fuze comprising electronic means to initiate three separate detonation outputs.
The first detonation output being used for round parachute deployment and fuze probe cover release. Simultaneously a mechanical timer is started which delays deployment of a six (6) foot stand-off probe until the parachute has slowed the round almost to its terminal speed.
The second detonation is initiated by depression and closure of a switch in the tip of the probe. This detonation initiates deployment a pair of detonators from the round that serve to ignite fuel that is later distributed to a prearranged site by a third explosive charge.
An automatic electronic timer of short duration is also initiated by the closure of the probe switch.
The third detonation is initiated by the automatic timer.
The third detonation initiates a burster charge for fuel dissemination, thus completing all three of the fuze explosive functions.
