Some Investigations into Coupling of E-Fields into Airframe Wiring
In the EU FULMEN collaborative project a series of experiments based on AEA Technology’s Hawker Hunter airframe have studied coupling of E and dE/dt threats.
Currents and fields were applied using either a low level lightning current simulator to the whole airframe, or by injecting the threats more locally.
Coupling could be measured in two apertures at opposite ends of the airframe, in which cables were routed both parallel and perpendicular to the current paths.
The different configurations for measurement and test allowed the various coupling methods to be separately elucidated.
Likely levels of E-field and d
coupled transients which could couple to internal equipment are discussed in relation to the present consensus of external environments.
