Abstract:

This report documents the results of four separate lightning simulation tests on a specially designed test bed aircraft. The simulation techniques used are low-level swept continuous wave, low-level fast rise pulse, moderate-level pulse, and shock-excitation. The test bed is made up of advanced composite materials with built-in lightning protection and electrical equipment installations. This configuration is electrically and geometrically representative of a general aviation heavy single engine aircraft. Comparative data was developed to determine the effectiveness of the four test methods and used to quantify differences between them. Analysis necessary to extrapolate the results of the tests to the severe lightning environment is discussed. Predicted values from computer models are compared with test results. Keywords Research aircraft Electromagnetic interference Atmospheric electricity hazards Aviation safety Composite materials Electronic equipment Simulation Lightning protection.
