  • Patent number: 6192741
    Abstract: In the improved system for sled-track testing of explosive missiles having tandem warheads and crush switches, time delay boards are placed on the sled to operate in conjunction with the crush switches to detonate the tip charge and the main warhead. The actual detonation is triggered by on-board firesets, one to detonate each warhead, that are optically coupled through an opto-coupler interface board which generates fire pulses in response to inputs received from the crush switch and the time delay board. These fire pulses are, in turn, transmitted to and activate the firesets.
