Evaluation of Current Conductivity of Composite Wiring Integrated Assembly for use on Bell / Agusta 609 Tiltrotor Aircraft 2001-01-2916

Electrical characteristics of composite Wiring Integrated Assembly (WIA) chassis’s when subjected to lightning environment are studied. The wiring architecture of the Bell Agusta Tiltrotor civil aircraft designated as Model BA609 includes WIAs that are shielded junction boxes. The WIAs are required to maintain wire bundle shield continuity to ground when exposed to the effects of a lightning event. Test results demonstrate that the composite WIAs having copper and nickel plating can withstand lightning currents up to 20 KA. A description of the WIAs, as well as lightning test procedure and results using waveforms 5A and 5B are presented.
