ABSTRACT:
An infrared safety beacon apparatus used on manned U.S. Army vehicles during live fire training exercises to distinguish them from heated silouette targets when exercise personnel use infrared viewers to observe the accuracy of fired rounds hitting the silouette targets. The apparatus includes a cylindrical shaped heater fixed to a vertical hollow tube attached to the tank. The infrared radiation emittal from the heater toward a viewer is controlled by a rotating cylindrically shaped chopper positioned over the heater. The chopper has openings over about one half of the circumference to provide intermittent flashes of infrared spectrum energy toward the viewer. The flashes are easily distinguishable from the steady infrared spectrum emitted from the silouette targets.
