Abstract

A digital timer fuze (DTF) in subcombination with a digital timer fuze sym. The central element in the fuze system is the aircraft fire-control computer including a fuze setter, which receives input signals from various sensors as required for rocket trajectory computations and, in addition, pilot commands. When the pilot arms the system and selects a firing mode, power is supplied to each fuze in the load. When the firing button (pickle switch) is depressed, timing commands are injected into each fuze in proper sequence and the rocket motors are initiated via circuits and initiators incorporated in the launcher pods. As each rocket moves forward under motor thrust, the lead to its fuze is separated. Physical interruption of this circuit initiates the "run" phase of the digital timer fuze. The digital timer fuze is electrically connected to the fuze setter. A signal from the fuze setter charges a power supply capacitor and causes a counter to count clock pulses for a given period of time and store the count. When the umbilical line connecting the fuze to the fuze setter is severed, the main counter counts down at a given rate. When all of the stored counts have left the counter, the counter gates an SCR which allows the power supply capacitor to actuate the detonator.
