Evaluation and mitigation of lightning hazards to the space shuttle Solid Rocket Motors (SRM)The objective was to quantify electric field strengths in the Solid Rocket Motor (SRM) propellant in the event of a worst case lightning strike. Using transfer impedance measurements for selected lightning protection materials and 3D finite difference modeling, a retrofit design approach for the existing dielectric grain cover and railcar covers was evaluated and recommended for SRM segment transport. A safe level of 300 kV/m was determined for the propellant. The study indicated that a significant potential hazard exists for unprotected segments during rail transport. However, modified railcar covers and grain covers are expected to prevent lightning attachment to the SRM and to reduce the levels to several orders of magnitude below 300 kV/m.
