ABSTRACT:

DEDICATORY CLAUSE
The invention described herein may be manufactured, used and licensed by or for the Government for governmental purposes without the payment to us of any royalties thereon.
BACKGROUND OF THE INVENTION
Current sled-track testing of missiles that have tip charges and crush switches, such as TOW-2A missiles, requires that off-board (i.e. Off-sled) electronic and mechanical equipment be used to detonate the warheads. Since the equipment used to detonate and time the warheads does not ride on the sled with the warhead, crush switch signals and delayed fire pulses from the missile electronics cannot be easily used to trigger the capacitive discharge units that fire the warheads. To detonate the warheads, special test equipment off-board is used to sense the sled's position with respect to target impact and activate the warheads when the sled reaches a pre-selected relative position. The timing for detonation of tandem warheads is also determined by off-board counters and timers. While this method produces adquate results for determining warhead effectiveness against the target, it does not account for variations in the performances of the crush switch and the time delay board (for tandem warheads) which can have significant effects on the warhead penetration of the target on the battlefield.
SUMMARY OF THE INVENTION
The improved system for sled-track testing of explosive missiles allows the use of the crush switch and the time delay board that are mounted to the sled along with the opto-coupler interface board, fire sets and battery housing. The actual detonation is performed by two on-board firesets, one to detonate each warhead, that are optically coupled through opto-coupler which isolates the time delay board signals from the fire sets. Fire pulses are generated from the crush switch and time delay board. These fire pulses are, in turn, transmitted to and activate the firesets, ultimately resulting in the detonation of the warheads in a manner that is closer to their performance on the battlefield and thereby yielding data that is more descriptive of their capabilities.
