OVERVIEW Trex Enterprises was contracted to develop a prototype generic Laser Hazard Detection System (gLHDS) for use on a UH-1 Huey helicopter on a very tight schedule. The system is designed to detect small cross-section hazards, including power lines, from a distance of more than 200 yards. Image clarity depends on the beam path length, the spot tolerances of the beam, and the amount of jitter induced during operation. Trex requested ATA’s support on the design of a cooling system to maintain the temperatures of all sensitive electronics in the detector enclosure below allowable limits and also on the design of a vibration isolation system to mount the detector to the helicopter. Trex was required to deliver a prototype less than 14 weeks after contracting ATA’s support. The pro
