Abstract:

Investigators have reported the existence of electric current in the exhaust plumes of rocket engines and have speculated that this current could generate a sufficiently high electrostatic potential on vehicles in space to interfere with or damage electronic subsystems or instrumentation. This paper identifies the source of the observed current, calculates its magnitude as a function of the engine parameters, and demonstrates that the rocket plume itself can discharge a vehicle in space and prevent buildup of dangerous potentials.
