Precipitation Static Electricity and Swept-Stroke Lightning Effects on Aircraft Transparency Coatings.
Abstract
Swept stroke lightning and static electric discharges on aircraft windshields and canopies will induce large electrical transient currents into the fragile transparent conductive coatings which are used for anti-icing, de-fogging, and radar cross section control of these transparencies. A test program was conducted to study possible detrimental effects of these transient currents. Representative aircraft transparencies were subjected to laboratory simulated swept stroke lightning magnetic fields and static electric charging. Damage assessment methods included visual inspection with normal and polarized light, electrical resistance measurements of the conductive coating, and thermal inspection using a closed circuit infrared television technique.
