Atmospheric Electricity Hazard (AEH) Assessment of Aircraft Transparencies.

摘要

A literature survey relating to the survivability of aircraft transparencies and electrical circuits embedded within them was performed. The types of materials used in transparencies and their edge construction were identified, the electrical properties of interest were defined along with test methods in use or available, the availability of electrical properties for the materials of interest was determined, the physiological hazards were documented, and analytical methods for evaluation of transparency systems were identified. As a result of this study it was concluded that the electrical parameters of interest are affected by temperature, frequency and exposure and that data for the materials of interest are not generally available over the ranges of interest for these parameters. It was also concluded that insufficient information is currently available for evaluation of the physiological hazards. Finally, analytical models for evaluation of transparency systems in an electromagnetic environment were found available that could be used to analyze transparency designs. However, these methods need to be computerized and validated. Recommendations are made to eliminate existing data gaps by tests and analyses. (Author)
