Helicopters in flight or hover accumulate a change of static electricity which, when discharged, could cause harm to personnel or ignite fuel. The project was established to study the charge and discharge characteristics of static electricity on the UH-2A helicopter and to evaluate the preproduction dynasciences model DO-3 discharger system. Flight tests were conducted during summer conditions when the available charging current and helicopter static voltages were low. The maximum charging current measured on the UH-2A helicopter was one microampere. The discharger system reduced a 20-kilovolt helicopter static voltage to a level between 0 to -800 volts in 0.5 second. The predicted maximum charging current for the UH-2A helicopter is 30 microamperes. The dynasciences model DO-3 discharger system provides an effective means to discharge static electricity from the UH-2A helicopter. Recommendations are made for redesign to adapt the discharger system to the UH-2A helicopter. (Author)
