The Estimation of Induced-Voltage Peak Magnitude and Energy Level Under LTA/EMP Excitation of Low-Loss Aircraft Cabling

The important vulnerability parameters of peak voltage transient magnitude and voltage transient energy are estimated for the LTA/EMP induction problem. Using basic linear system theory, straightforward expressions are derived to estimate these two survivability parameters. The derived model is quite general including cable characteristics, varying terminating impedances , and varying points of cable excitation. Using the developed model, a comparison of the LTA and EMP cases is made. An iliustrative example involving the yaw-damper circuit of the USAF f-l11 is also included.
