Abstract : Numerous incidents of severe shock to ground personnel and potential hazards to cargo during external sling load cargo operations have led to extensive research efforts aimed at the dissipation of high electrostatic energy levels present on helicopters. The Model D-03 Electrostatic Discharger is essentially a closed-loop servo system. The report covers its fabrication, mechanical evaluation, environmental testing, and flight testing under both arctic and dusty/high-humidity conditions. Drawings and photographs are included in the report as an aid to a thorough understanding of the system.
