Aircraft and other airborne vehicles naturally acquire electrical charge during flight, due mainly to frictional charging by precipitation particles such as ice, snow, rain, or dust. If not properly managed using precipitation-static dischargers, or p-static wicks, corona discharges can form on the sharp edges of radio antennae, causing communication interference that impairs flight safety. The basic operation of these passive devices of charge control is explained by the onset of a controlled corona discharge at the tip of the wick whenever the aircraft acquires charge beyond the inception threshold of the discharge. Whereas testing standards are in place to quantify the charge dissipation rates of the wicks and their electromagnetic noise, these typically ignore aspects inherent to being airborne, such as sub-atmospheric pressure conditions or wind advection. In this work, wind tunnel experiments are conducted to characterize the behavior of corona discharge from commercial p-static wicks, mounted in standard testing configurations, subjected to DC voltage, and exposed to wind. The results from this experimental campaign reveal the effects of wind speed on the discharge properties, including which discharge mode is being favored (e.g., glow versus streamer corona), the streamer burst pulsation frequency, as well as current characteristics. These observations have implications in terms of the discharging efficiency of p-static wicks as well as their interference frequencies.
