Aircraft Cable Parameter Study.
Abstract
This report describes experimental and analytical results obtained from a study of the transmission line properties of multiconductor cables commonly found on aircraft. A method for the complete characterization of multiconductor transmission lines in inhomogeneous media is presented and verified experimentally. Bulk transmission line properties of bundles containing up to 20 closely spaced wires were measured for cases of a bundle near a flat ground plane, near a corner, and in conduit. The results are compared with single wire handbook formulas and discussed. Perturbations on transmission lines caused by bulkheads, cable clamps, and the ribbed interior of aircraft were measured for several cases. It was found that the perturbations could be treated as lumped capacitive loads on an otherwise uniform line. Cable parameter measurements conducted on board an EC-135 aircraft are presented and discussed.
