MEASUREMENT PROGRAM TO DETERMINE STATIC ELECTRICITY CHARGING CURRENTS IN HELICOPTER MAIN ROTOR BLADES

Abstract

A SH-3A main rotor blade was electrically insulated from the rotor head and connected to measuring apparatus to determine to what extent the main rotor blades contributed to the electrostatic charges on helicopters. Testing was performed on test stands and on a SH-3A helicopter in various environmental conditions. It was found that in clear-air conditions (no snow, sand, rain, etc.) electrostatic charging current due to main rotor blades is relatively small compared to the helicopter's total current; however, in environmental conditions (snow, sand, rain, etc.) the main rotor blades are the major contributors of electrostatic charging current.
